Description:FIELD OF THE INVENTION

[0001] The present disclosure relates to a dust collector. More particularly, the present disclosure relates to a fragmented projectile extraction system and a coupling assembly thereof.

BACKGROUND

[0002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.

[0003] Generally, transportation of solid materials is done along with an air stream in a controlled environment during industrial processes, to ensure handling of bulk solid materials, while preventing any degradation thereof.

[0004] Conventionally, there exist systems and techniques that are used for transportation of solid materials along with an air stream in a controlled pressure environment and at high velocity through conduits, to ensure efficient transfer of solid material. Such techniques are for instance, without limiting thereto, used in bullet training through bullet proof traps (BPTs) for extracting debris from bullet impact, fragments of bullets, and the like. It is necessary to extract debris created from bullet, since a large fragment created upon bullet impact may enter the respiratory organs of a user causing health issues. There exist techniques that suggest removal of a protective material from the bullet during bullet training through BTPs. Even though removal of the protective layer from the bullet ensures that lesser creation of debris, however, there exists certain issues with the existing techniques of removal of debris at the time of firing the bullet. Due to removal of the protective layer, a firearm through which the bullet without the protective layer is fired can be malfunctioned and create a hazard by being directed at certain areas in the BPTs creating a hotspot through continuous direction of incoming bullet without a protective layer. Correspondingly, in an instance, an incoming bullet can stuck at the hotspot and cause ricochet. As a result, the user firing the bullet and other users in the BPT may be at risk of an injury and accidents in case bullets are fired after protective layer is removed.

[0005] Further, there also exist techniques that suggest that the high velocity speed of such a combined stream of solid materials, such as the bullet along with air steam in the controlled pressure environment creates force, thereby causing the combined stream to be passed through the conduits. However, for efficient transfer of the solid materials through the combined stream, it is necessary for the conduits to remain sealed and that the pressure and velocity of the combined stream is maintained. In case the pressure and velocity are not maintained, the conduits can be impacted, such that the conduits can be clogged and even leakage of the combined stream can take place through the conduits. In bullet training facilities, without limiting the scope thereto, buckets are used as containers to collect solid materials passed from such conduits.

[0006] Therefore, it is desirable to provide a fragmented projectile extraction system that can address one or more limitations associated with the existing art.

[0007] The drawbacks/difficulties/disadvantages/limitations of the conventional techniques explained in the background section are just for exemplary purposes and the disclosure would never limit its scope only such limitations. A person skilled in the art would understand that this disclosure and below mentioned description may also solve other problems or overcome the other drawbacks/disadvantages of the conventional arts which are not explicitly captured above.

SUMMARY

[0008] This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention nor is it intended for determining the scope of the invention.

[0009] The present disclosure relates to a fragmented projectile extraction system. The fragmented projectile extraction system includes a collection funnel, a coupling assembly, and a collection bin. The coupling assembly coupled to the collection funnel includes a first plate, a second plate and a coupler. The second plate is coaxially placed with respect to the first plate and fastened to the first plate, where the second plate includes a predefined cut adapted to form a locking chamber. The coupler includes a body, a header, and a plurality of fasteners. The header includes a predefined profile, where the header is adapted to releasably couple to the locking chamber. The plurality of fasteners adapted to fasten the first plate to the second plate, and adapted to change tautness between the first plate and the second plate to enable and disable a rotation of the header in the locking chamber. Further, the collection bin coupled to body of the coupler.

[0010] In another embodiment, a coupling assembly is disclosed. The coupling assembly coupled to the collection funnel includes a first plate, a second plate and a coupler. The second plate is coaxially placed with respect to the first plate and fastened to the first plate, where the second plate includes a predefined cut adapted to form a locking chamber. The coupler includes a body, a header, and plurality of fasteners. The header includes a predefined profile, where the header is adapted to releasably couple to the locking chamber. The plurality of fasteners adapted to fasten the first plate to the second plate, and adapted to change tautness between the first plate and the second plate to enable and disable a rotation of the header in the locking chamber. In one example, the plurality of fasteners may include a minimum of three fasteners. Further three fasteners may be needed to provide a greater range in the tautness adjustment between the first plate and the second plate.

[0011] In view of the above, the coupling assembly of the fragmented projectile extraction system may effectively be coupled with the collection funnel and the collection bin. Accordingly, the coupling assembly may ensure that there may be no leakage and consequently, no changes in pressure or speed of dust air stream passing therethrough may be caused. The second plate may be coaxially placed with respect to the first plate and fastened to the first plate to form a locking chamber, such that the header of the coupler may be removably coupled to the locking chamber. The plurality of fasteners may be adapted to fasten the first plate to the second plate, such that the plurality of fasteners may one of fasten and unfasten to change degree of tautness between the first plate and the second plate.

[0012] In this regard, when the plurality of fasteners may be fastened to create high degree of tautness between the first plate and the second plate, the header coupled at the locking chamber may be locked. In such an instance, the rotation of the header in the locking chamber may be disabled because of the high degree of tautness between the first plate and the second plate. Correspondingly, the sealing through the coupling assembly in such an instance, may be high, such that pressure and speed may be maintained therebetween. Further, the coupling assembly may also prevent any leakage therethrough when the plurality of fasteners may fasten to increase the degree of tautness the first plate and the second plate. In this manner, the implementation of the coupling assembly may effectively couple the collection funnel and the collecting bin, while maintaining sealing and preventing and leakage therebetween.

[0013] Further, without limiting the scope of the present disclosure, in an instance of bullet training at BPTs, the fragmented projectile extraction system of the present disclosure may through the sealing through the coupling assembly may extract large fragments, such as lead that may be created after the bullet impact and prevent any leakage therethrough.

[0035] Embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings.

[0036] Figures 1 to 3 illustrate different orientations of a fragmented projectile extraction system 100 and have been explained in conjunction with each other.

[0037] Figure 1 illustrates an isometric view of a fragmented projectile extraction system 100, according to an embodiment of the present disclosure. Figure 2 illustrates a sectional view of the fragmented projectile extraction system 100, in accordance with an embodiment of the present disclosure. Figure 3 illustrates an exploded view of the fragmented projectile extraction system 100, in accordance with an embodiment of the present disclosure.

[0038] The fragmented projectile extraction system 100 of the present disclosure may be adapted to be used in bullet training facilities using bullet proof traps (BPTs) for extracting dust, such as debris, bullet fragments, lead and the like, to ensure health, safety, cleanliness and regulatory compliance for such bullet training. The fragmented projectile extraction system 100 of the present disclosure may receive fragmented elements in projectile motion, and may be adapted to extract the fragmented elements.

[0039] The fragmented projectile extraction system 100 of the present disclosure includes a collection funnel 102, a coupling assembly 104 and a collection bin 106.

[0040] The collection funnel 102 may be adapted to be positioned in proximity to a bullet trap, such that the collection funnel 102 may receive dust air stream. The dust air stream may include, but is not limited to, air flow and dust. In an example, the dust may include, but not limited to, dust particles, bullet fragments, bullet residue, and the like. In an example, the bullet residue may include, not limited thereto, gunpowder, lead residue, and the like.

[0041] The collection funnel 102 of the present disclosure, as illustrated in Figures 1-3, may have a funnel-shaped body having a first funnel end 102-1 and a second funnel end 102-2 distal to the first funnel end 102-1. The second funnel end 102-2 may have a circular-shaped funnel flange 104 extending radially therefrom. The collection funnel 102 may be coupled with the coupling assembly 104 through the circular-shaped funnel flange 104, as will be explained later.

[0042] The first funnel end 102-1 may be adapted to receive the dust air stream, such that the funnel-shaped body may allow dust-air stream to enter therefrom. A diameter of the second funnel end 102-2 may be lesser than a diameter of the first funnel end 102-1. In this regard, as the dust air stream passes through the funnel-shaped body, the dust air stream may be guided through the second funnel end 102-2 towards the coupling assembly 104.

[0043] As shown in Figure 3, the coupling assembly 104 may include a first plate 108, a second plate 110 and a coupler 112.

[0044] The first plate 108 may be circular-shaped plate having a hole 111 provided therebetween. The first plate 108 may have a first portion 108-1 and a second portion 108-2 opposite to the first portion 108-1. The first portion 108-1 of the first plate 108 may be coupled with the second funnel end 102-2 to be coaxially placed with respect to each other. In an example, the first plate 108 may be coupled with the collection funnel 102 through fastening elements, such as screw, bolts, and the like. The first plate 108 may have a plurality of internal ridges 114 provided about the hole 111. The plurality of internal ridges 114 may be designed in a manner to allow coupling with the coupler 112 through the second plate 110, as will be explained later.

[0045] The second plate 110 may be circular-shaped plate having a predefined cut 126. The second plate 110 may have a first surface 110-1 and a second surface 110-2 opposite to the first surface 110-1, as shown in Figure 3. The second plate 110 may be fastened with the first plate 108, such that the first surface 110-1 of the second plate 110 may be fastened with the second portion 108-2. The plurality of fasteners 116 may be adapted to fasten the first plate 108 and the second plate 110 with respect to each other. In the illustrated example, the plurality of fasteners 116 may include three fasteners. Even though the illustrated embodiment shows the plurality of fasteners 116 including three fasteners, however, the implementations of the present disclosure are not limited thereto and may number of fasteners may vary based on the requirement of coupling and extraction of fragments. In one example, the plurality of fasteners 116 may be a wing-nut, as will be explained later.

[0046] Corresponding to the first plate 108, the second plate 110 may have a hole corresponding to the hole 111 of the first plate 108, when the second plate 110 may be co-axially aligned and fastened with respect to each other. In this regard, the hole of the second plate 110 may correspond to the hole 111. Accordingly, a locking chamber 124 may be formed through the predefined cut 126 between the first plate 108 and the second plate 110, where the plurality of internal ridges 114 provided about the hole 111 may provide space and volume for the locking chamber 124.

[0047] In an example, a sealing member 125 may be disposed on an inner surface of the first plate 108. The sealing member 125 may be adapted to be disposed in the locking chamber 124 to aid in effective sealing and maintain low pressure and high speed for the dust air stream passing therethrough as will be explained later.

[0048] The coupler 112 may include a header 118 and a body 120. The header 118 may have a predefined profile 122. The body 120 of the coupler 112 may have a hole corresponding to the hole 111 of the first plate 108, when co-axially aligned with the first plate 108 and the second plate 110. In this regard, the hole of the coupler 112 may correspond to the hole 111. The predefined profile 122 may include at least three flanges extending radially at a distance from one another. The predefined profile 122 may include at least three flanges extending radially from the hole of the coupler at a distance from one another. The predefined profile 122 may correspond to the predefined cut 126. Accordingly, the coupler 112 may be releasably coupled to the locking chamber 124 through the header 118. In other words, the predefined profile 122 having a design corresponding to the predefined cut 126 may aid in releasably coupling of the coupler 112 in the locking chamber 124, as will be explained later.

[0049] The body 120 of the coupler 112 may include a circular flange 121 extending from a bottom end 120-1 of the body 120 thereof, where the bottom end 120-1 may be distal to the header 118. Further, the body 120 of the coupler 112 may be coupled to the collection bin 106. In an example, the body 120 of the coupler 112 may be coupled through the circular flange 121 to the collection bin 106 through fastening elements.

[0050] The first plate 108, the second plate 110 and the body 120 of the coupler 112 may include the hole 111 coaxially aligned to define a conduit 128, such that the dust air stream may be allowed to pass through the conduit 128.

[0051] The coupling assembly 104 may couple the collection funnel 102 with the collection bin 106. The collection funnel 102, the collection bin 106 and the coupling assembly 104 may be co-axially coupled with another to allow effective passing of the dust air stream.

[0052] The coupling assembly 104 of the present disclosure may be designed to guide the dust air stream from the collection funnel 102 towards the collection bin 106, while maintaining the pressure and speed of the dust air stream passing therethrough. The coupling assembly 104 may provide effective sealing between the collection funnel 102 and the collection bin 106, such that there is no leakage, backflow, clogging issues and damage to the fragmented projectile extraction system 100 and its components. The coupling assembly 104 may be designed in a manner to maintain the low pressure and high velocity of dust air stream constantly throughout the transmission by providing effective sealing between the collection funnel 102 and the collection bin 106, as will be explained later.

[0053] The collection bin 106 may be a cylindrical-shaped container coupled to the coupling assembly 104. The collection bin 106 may be adapted to collect the dust from the dust air stream.

[0054] Figures 4 and 5 include components of the coupling assembly 104 and have been explained in conjunction with each other.

[0055] Figure 4 illustrates an isometric view of a first plate 108 and a second plate 110 of the coupling assembly 104 assembly forming the locking chamber 124, in accordance with an embodiment of the present disclosure. Figure 5 illustrates an isometric view of a coupler 112 of the coupling assembly 104, in accordance with an embodiment of the present disclosure.

[0056] The coupling assembly 104 of the present disclosure, as illustrated above, may be employed to provide an effective sealant between components, such as the collection funnel 102 and the collection bin 106 of the fragmented projectile extraction system 100. Even though the coupling assembly 104 has been explained with respect to the fragmented projectile extraction system 100 that may be employed in bullet training facilities using bullet proof traps (BPTs), however, the implementations of the coupling assembly 104 are not limited thereto. The coupling assembly 104 may be employed in industries and facilities that require to transfer air stream containing solid matter in a controlled pressure and speed. The coupling assembly 104 may be employed in industries and facilities that require to transfer air streams containing solid matter while maintaining low pressure and high velocity of the air stream containing solid matter. In an example, the coupling assembly 104 may be employed in, without limiting the scope of implementation thereto, pharmaceutical processing, food processing, agricultural industry, construction industry, and the like.

[0057] In this regard, even though the coupling assembly 104 has been explained with respect to the fragmented projectile extraction system 100 that may be employed in bullet training facilities using bullet proof traps (BPTs), the implementations of the coupling assembly 104 are not limited thereto. The coupling assembly 104 may be employed in any facility, system, unit, that require effective sealing to transfer air stream containing solid matter while maintaining low pressure and high velocity of the air stream containing solid matter.

[0058] As stated above, the first plate 108 and the second plate 110 may be fastened with each other through the plurality of fasteners 116. In an example, the plurality of fasteners 116 may include three wing nuts arranged in a circular fashion on a top surface 402 of the coupler 112. The plurality of fasteners 116 may be adapted to change tautness between the first plate 108 and the second plate 110 to one of enable and disable a rotation of the header 118 in the locking chamber 124. This enablement and disablement of rotation of header 118 may correspond to the coupling of the coupler 112 with the first plate 108 and the second plate 110.

[0059] In instance, the plurality of fasteners 116 may be unfastened to reduce degree of tautness therebetween, may allow the predefined profile 122 to be moved in the locking chamber 124 and be one of coupled and released. As shown in Figure 3, the hole on the second plate 110 may correspond to the hole 111 of the first plate 108. The predefined cut 126 provided on the second plate 110 and the plurality of internal ridges 114 may have similar pattern, design and dimensions, however, the first plate 108 and the second plate 110 may be fastened in a manner that the predefined cut 126 may not align with the plurality of internal ridges 114, as shown in Figure 4. The space corresponding to the plurality of internal ridges 114 in the first plate 108, may provide sufficient volume for the coupler 112 through the predefined profile 122 of the header 118 to be one of be accommodated and released into the locking chamber 124. In one instance, in order to couple, the header 118 through the predefined profile 122 may be inserted through the predefined cut 126 and may be rotated towards the space corresponding to the plurality of internal ridges 114 in the first plate 108 to be coupled therein. In another instance, in order to release, the header 118 through the predefined profile 122 may be rotated in the space corresponding to the plurality of internal ridges 114 in the first plate 108 to be released through the predefined cut 126.

[0060] In another instance, the plurality of fasteners 116 may be fastened to increase tautness between the first plate 108 and the second plate 110. Accordingly, in case the header 118 may be coupled therebetween, any movement of the header 118 may be restricted until degree tautness may be changed.

[0061] The change in tautness between the first plate 108 and the second plate 110 through the plurality of fasteners 116, may correspond to the sealing between the components coupled with the coupling assembly, such as the collection funnel 102 coupled with the first plate 108 and the collection bin 106 coupled with the coupler 112. In an instance, when the degree of tautness may be increased, the sealing between the components coupled with the coupling assembly 104 may be increased. In another instance, when degree tautness may be decreased, the sealing between the components coupled with the coupling assembly 104 may also be removed.

[0062] Further, in order to more effectively seal the components coupled with the coupling assembly 104, the sealing member 125 may be provided in the inner surface of the first plate 108. In this instance, when the header 118 may be inserted in through the predefined cut 126 for coupling in the locking chamber 124, the sealing member 125 may be adapted to abut a top surface 402 of the header 118. A degree of tautness that may have been caused by at least one of fasteners 116 may correspondingly affect the state of the sealing member 125. State of the sealing member 125 may be at least one of an uncompressed state and a compressed state. In instance, when the degree of tautness may be increased, the sealing member 125 may be caused to be in the compressed state and abutting on the top surface 402 of the header 118. In this regard, the increase of degree of tautness caused by the fastening through the plurality of fasteners 116 along with the sealing by the sealing member 125 in compressed state, may increase the sealing, such that any leakage of dust air stream through the conduit 128 may be prevented while the pressure and speed of the dust air stream may be maintained. The sealing member 125 in the compressed state may lock the rotation of the header 118 inside the locking chamber 124.

[0063] In another instance, when the plurality of fasteners 116 may be unfastened to reduce the degree of tautness, in such an instance, the sealing member 125 may be moved to uncompressed state. In this instance, the sealing member 125 in the uncompressed state may unlock the rotation of the header 118 inside the locking chamber 124. In view of the above, the sealing member 125 may be in of one of an uncompressed state and a compressed state based on the degree of tautness between the first plate 108 and the second plate 110.

[0064] In view of the above, the adjustment of degree of tautness through the plurality of fasteners 116 between the first plate 108 and the second plate 110 along with the sealing member 125 may aid in effectively controlling the sealing in the coupling assembly 104. Accordingly, any leakage of dust air stream through the conduit 128 may be prevented while the pressure and speed of the dust air stream may be maintained.

[0065] Figure 6 illustrates an exploded view of a coupling assembly 104 of the fragmented projectile extraction system 100, in accordance with an embodiment of the present disclosure. Figure 7 illustrates a sectional view of the coupling assembly 104 in an unlocked state, in accordance with an embodiment of the present disclosure. Figure 8 illustrates a sectional view of the coupling assembly 104 in a locked state, in accordance with an embodiment of the present disclosure.

[0066] As stated above, the coupling assembly 104 may aid in sealing and preventing any leakage of the dust air stream in the fragmented projectile extraction system 100 while maintaining the pressure and the speed of the dust air stream entering therein.

[0067] In the case of the fragmented projectile extraction system 100, as shown in Figure 6, the first plate 108 may be coupled to the collection funnel 102 and the coupler 112 may be coupled to the collection bin 106. As stated above, the header 118, may through the predefined profile 122, may engage with the predefined cut 126 to be coupled in the locking chamber 124. Figure 7 illustrated a state when the header 118 may be engaged with the locking chamber 124 but may not have been locked and the coupling assembly 104 may be in unlocked state. In order to effectively move the coupling assembly 104 to a locked state, the header 118 may be caused to rotate in the space in the locking chamber 124 i.e., the space corresponding to the plurality of internal ridges 114 of the first plate 108. In this regard, as shown in Figure 8, the coupling assembly 104 may be moved to the locked state.

[0068] To further enhance the sealing and locking in the coupling assembly, the plurality of fasteners 116 may be fastened to increase the degree of tautness between the first plate 108 and the second plate 110 with the header 118 coupled in the locking chamber 124. In such an instance i.e., when the degree of tautness may be increased, the sealing member 125 may be caused to move to compressed state, thereby abutting against the top surface 402 of the header 118. In this instance, the coupling assembly 104 may be in locked state, such that the dust air stream entering through the containing funnel 102 may be passed through the conduit 128, while the pressure and speed of the dust air stream may be maintained. The effective sealing caused by increase of degree of tautness between the first plate 108 and the second plate 110, along with the sealing member being in compressed state may effectively seal the coupling assembly 104.

[0069] The coupling assembly 104 of the present disclosure may also provide protection from any inadvertent movement that may cause leakage. In an instance, in the locked state i.e., when the degree of tautness may be high and the sealing member 125 may be in compressed state abutting on the header 118 of the coupler 112 that may be connected to the containing bin 106. In case, the containing bin 106 may be inadvertently caused to move because of external pressure, the header 118 may not be actuated or rotated in the locking chamber 124. The high degree of tautness between the first plate 108 and the second plate 110 along with the sealing member 125 in compressed state, both may lock the header 118 in the locking chamber 124 thereby providing more protection from any leakage.

[0070] Figures 9 and 10 illustrate another embodiment of the coupling assembly 104 that may include a coupler adapted to couple to a locking chamber in a single orientation and correspondingly, decoupling in an orientation opposite to the single orientation. Figure 9 illustrates a sectional view of the coupling assembly in an unlocked state, in accordance with another embodiment of the present disclosure. Figure 10 illustrates a sectional view of the coupling assembly in a locked state, in accordance with another embodiment of the present disclosure. In this regard, Figures 9 and 10 have been explained in conjunction with each other.

[0071] In the illustrated embodiment, the first plate 900, the second plate 902 and the coupler 904 may have similar features and correspond to the first plate 108, the second plate 110 and the coupler 112 illustrated above, except for the predefined profile of the header, the plurality of internal ridges of the first plate and the predefined cut of the second plate. The first plate 900, the second plate 902 and the coupler 904 may couple in a similar manner as illustrated above the same has not been repeated herein again for the sake of brevity. Additionally, change in tautness between the first plate 900 and the second plate 900 through the plurality of fasteners 116, the sealing by the sealing member 125 and the locking chamber 124 may be similar to as illustrated above and the same has not been repeated herein again for the sake of brevity.

[0072] In the present embodiment, the predefined profile 904-1 of the coupler 904 may include at least three flanges i.e., a first flange 906, a second flange 908 and a third flange 910 extending radially from the hole of the coupler 904 at a distance from one another.

[0073] In the illustrated embodiment, the first flange 906 and the second flange 908 may have similar profile and, the third flange 910 may have different profile than the first flange 906 and the second flange 908. In an example, the third flange 910 may be smaller in size than the first flange 906 and the second flange 908. In another example, the third flange 910 may be bigger in size than the first flange 906 and the second flange 908. In yet another example, the third flange 910 may be designed to have any of a different pattern or shape than the first flange 906 and the second flange 908. Even though the illustrations herein have been explained with respect to the coupler 904 having at least three flanges, the coupler 904 may have any number of flanges based on the requirement of coupling. Further, even though in the illustrations the third flange 910 may have different pattern or shape than the first flange 906 and the second flange 908 however, the implementations of the present disclosure are not limited thereto and any of the flanges from the predefined profile 904-1 may be different from other of the flanges to allow easy and secure coupling in one orientation and decoupling in an orientation opposite to the one orientation of coupling.

[0074] Correspondingly, in order to couple the coupler 904 with the first plate 900 and the second plate 902, the predefined cut 902-1 at the second plate 902 may correspond to the predefined profile 904-1 on the coupler 904 and the plurality of internal ridges 900-1 may be designed in a manner to allow coupling with the coupler 904 through the second plate 902.

[0075] Accordingly, the predefined profile 904-1 and the predefined cut 902-1 may be designed to be corresponding to each other that may aid in releasably coupling the coupler 904 in the locking chamber between the first plate 900 and the second plate 902. In an example, the predefined cut 902-1 provided on the second plate 902 and the plurality of internal ridges 902 may have similar pattern, design and dimensions, however, the first plate 900 and the second plate 902 may be fastened in a manner that the predefined cut 902-1 may not align with the plurality of internal ridges 900-1, as shown in Figure 9. The space corresponding to the plurality of internal ridges 900-1 in the first plate 900, may provide sufficient volume for the coupler 904 through the predefined profile 904-1 to be one of be accommodated and released into the locking chamber.

[0076] In the case of the fragmented projectile extraction system 100, as shown in Figure 6, the first plate 900 may be coupled to the collection funnel 102 and the coupler 904 may be coupled to the collection bin 106. As stated above, the header of the coupler 904 may through the predefined profile 904-1 may engage with the predefined cut 902-1 to be coupled in the locking chamber. The predefined profile 904-1 of the present embodiment, through the different profile and shape of the third flange 910 than the first flange 906 and the second flange 908 in the same predefined profile 904-1, may aid in effectively engaging the predefined profile 904-1 with the predefined cut 902-1.

[0077] Figure 9 illustrated a state when the coupler 904 may be engaged with the second plate 902 at the locking chamber but may not have been locked and the coupling assembly may be in unlocked state. In order to effectively move the coupling assembly 104 to a locked state, as shown in figure 10, the coupler 904 may be caused to rotate in the space between the first plate 900 and the second plate 902 in the locking chamber 124 i.e., the space corresponding to the plurality of internal ridges 900-1 of the first plate 900. In this regard, as shown in Figure 10, the coupling assembly may be moved to the locked state.

[0078] In view of the above, the coupling assembly 104 of the fragmented projectile extraction system 100 may effectively be coupled with the collection funnel and the collection bin. Accordingly, the coupling assembly 104 may ensure that there may be no leakage and consequently, no changes in pressure or speed of dust air stream passing therethrough may be caused. The second plate 110 may be coaxially placed with respect to the first plate and fastened to the first plate to form the locking chamber 124, such that the header 118 of the coupler 112 may be removably coupled to the locking chamber 124. The plurality of fasteners 116 may be adapted to fasten the first plate to the second plate 110, such that the plurality of fasteners 116 may be one of fasten and unfasten to change degree of tautness between the first plate and the second plate 110.

[0079] In this regard, when the plurality of fasteners 116 may be fastened to create high degree of tautness between the first plate and the second plate 110, the header 118 coupled at the locking chamber 124 may be locked. In such an instance, the rotation of the header 118 in the locking chamber 124 may be disabled because of the high degree of tautness between the first plate 108 and the second plate 110. Correspondingly, the sealing through the coupling assembly 104 in such an instance, may be high, such that pressure and speed may be maintained therebetween. Further, the coupling assembly 104 may also prevent any leakage therethrough when the plurality of fasteners 116 may fasten to increase the degree of tautness the first plate and the second plate 110. In this manner, the implementation of the coupling assembly 104 may effectively couple the collecting funnel and the collecting bin, while maintaining sealing and preventing and leakage therebetween.
