TECHNICAL FIELD
Present disclosure relates to a field of automobiles. Further aspects of the present disclosure relates to an apparatus for dislodging material from a vehicle structure. Particularly, embodiments relates to, the apparatus and a method to dislodge material accumulated on a surface of vehicle structure of the vehicle.
BACKGROUND OF THE DISCLOSURE
In general, heavy duty transport vehicles such as a dumper or tipper trucks have a carrier portion to carry and store materials such as soil, gravel, sand, debris, coal, crushed stones, and other flowable particulate matter. It is well known that these carriers are pivotable by any hydraulic or pneumatic lifting mechanisms installed within the vehicles, to unload the material from the vehicle, using gravity. Sometimes, there is a scenario of accumulation of material within the carrier because of clogging of material due to moisture content and type of the material. Even after lifting the carrier to a considerable lifting angle, there exists a problem of accumulation of material on a surface of the carrier. Moreover, there exists a limitation in the lifting angle of the carrier, in order to maintain stability of the vehicle and to avoid overturing. Thus, complete unloading of the material from the vehicle is not always possible, and this necessitates manual removal of the accumulated material, where a person has to climb on the carrier and then manually shovel or remove the material stuck to walls of the carrier.
Additionally, an inner surface of the carriers in conventional vehicles are provided with coating, liners, and mechanical shovel type arrangements to dislodge and remove the accumulated material. However, coatings and liners are unlikely to be durable and their effectiveness may reduce, as they require frequent replacement and continuous maintenance. Moreover, provision of mechanical shovel arrangements requires additional mechanism to operate, thereby increasing overall weight and cost of manufacture.
The present disclosure is directed to overcome one or more above limitations stated above or any other limitation associated with the prior arts.

Heavy duty vehicles including dumper or tipper truck have vessel or carriers to store and transport materials. These vessels and carriers are pivotable by lifting mechanisms installed within the vehicles, to unload the material from the vehicle, using gravity. Sometimes, accumulation of material occurs within the carrier because of hang up and clogging of material due to moisture content and type of the material. Even after lifting the carrier to a considerable lifting angle, there exists a problem of accumulation of material on a surface of the carrier. Conventionally, an inner surface of the carriers are provided with coating, lines or mechanical mechanism such as shovel

mechanisms to force dislodging of accumulated materials. However, these coatings and mechanism are not durable, due to frequent replacement and maintenance. Thus, increasing operational costs. Accordingly, an apparatus to dislodge accumulated material from a surface of a vehicle structure of a vehicle of the present disclosure is configured to overcome the problems associated with the conventional mechanisms. The apparatus of the present disclosure comprises a frame coupled to the surface of the vehicle structure. A plurality of vents defined on the frame are fluidly connected to at least one fluid supply line to selectively supply pressurized fluid. Further, at least one acoustic emitter unit is arranged within the frame to selectively radiate acoustic wave pulses to the panel. The radiated acoustic wave pulses is emitted in conjunction with the pressurized fluid. Therefore, the apparatus of the present disclosure aids in dislodging accumulated material from the surface of the vehicle structure.
Referring to Figures 1 to 2 which are exemplary embodiments of the present disclosure illustrating an apparatus to dislodge accumulated material (100) [interchangeably referred as “apparatus (100)”] from a surface of a vehicle structure (210) of the vehicle.
The apparatus (100) comprises a frame (10a) coupled to the surface of the vehicle structure (210). Further, the frame (10a) is configured to receive a panel (10) therein. Further, the frame (10a) is provided along an entire periphery of the panel (10) thereby. The panel (10) within the frame (10a) is having a top surface and a bottom surface. The frame (10a) is designed such that, a plurality of vents (20) are defined at predetermined locations within the frame (10a). In an embodiment, the plurality of vents (20) may be disposed in an array formation on the top portion. The plurality of vents (20) may be a hole, a slot provided on a portion or completely on the panel (10). The panel (10) may be mounted to the surface of vehicle structure (210), such that the plurality of vents (20) is in contact with the material stuck to it or accumulated at a portion of the vehicle structure (210). The vehicle structure (210) may be at least one of carrier, vessel of a tipper/ dumper vehicle which is configured to store and transport the material. The material is accumulated or stuck to an inner surface of the vehicle structure (210) due to presence of moisture or type of material that needs to be dislodged.
The present disclosure further includes at least one fluid supply line [not shown in figure] fluidly connected to each of the plurality of vents (20). The at least one fluid supply line is configured to

selectively supply pressurised fluid to the frame (10a) and thereby to the plurality of vents (20). Further, the at least one fluid supply line is in fluid communication with an air supply unit (not shown). The fluid supply unit is configured to selectively generate and supply pressurised fluid to the frame (10a) via the plurality of vents (20). The fluid supply unit may be a fluid compressor that is configured to generate pressurised air as per application requirement. In an embodiment, the at least one fluid supply line includes one or more conduits that is in fluid communication with the fluid supply unit. In an embodiment, the fluid supply unit may be an air supply unit. The air supply unit may include air compressor that sends out pressurized air through the plurality of vents (20), however the same shall not be considered as limitation. The air supply unit is provided in proximity of the vehicle structure (210) and to the panel (10). As an example, the air supply unit may be configured to a chassis of the vehicle. A pressure of the air to be supplied to the frame (10a) can be altered depending on the requirement, the air supply unit is actuated to supply the predetermined pressurised fluid into the panel (10) and to the plurality of vents (20), thereby by making the accumulated material on the surface of the vehicle structure (210) to vibrate due to contact of the panel (10) with vehicle structure (210). In an embodiment, the plurality of vents () may be protected with a cover member having low friction material enabling smooth sliding once the pressurised fluid flows from each of the vents (20). Further, a flow rate and the pressure of the fluid by the fluid supply unit can be varied as per application requirement.
The apparatus (100) further comprises at least one acoustic emitter (30) arranged within the frame (10a) to selectively radiate acoustic wave pulses towards the surface of vehicle structure (210). In an embodiment, each of the acoustic emitters (30) is arranged proximal to each of the plurality of vents (20). The radiated acoustic wave pulses in conjunction with supplied pressurized fluid, aids in amplifying the acoustic wave pulses. This amplified acoustic wave pulses along with pressurised fluid dispensed from the panel (10) contacts the accumulated material on the vehicle structure (210) via the plurality of vents (20) respectively, which causes the accumulated material to agitate and vibrate thereby dislodging the accumulated material from the surface of vehicle structure (210).

The present disclosure further discloses a vehicle comprising a chassis and a vehicle structure (210) connected to the chassis. The vehicle structure (210) is configured to selectively tilt from a first position (FP) to a second position (SP). In an embodiment, a tilting mechanism is mounted on the chassis and coupled to a bottom portion of the vehicle structure (210), to selectively tilt

from the first position (FP) to the second position (SP) for unloading the material from the vehicle structure (210). The second position (SP) may be an elevated position of the vehicle structure when the tilting mechanism is actuated. The frame (10a) along with the panel (10) of apparatus (100) of the present disclosure is mounted to at least a portion of the vehicle structure (210). Further, an array of panels (10) may be mounted to the vehicle structure (210). The vehicle structure (210) may be defined with walls (210b) [i.e. side walls] extending upwardly from a periphery of a base or may be a cylindrical shaped container. The frame (10a) may be provided on any portion of the base (210a), walls or surface of the cylindrical shaped container of the vehicle. The number of frames (10a) may be chosen based on the requirement and size of the vehicle structure (210). The positioning of the frame (10a) can be varied as per application requirements. In an embodiment, the apparatus (100) for dislodging the accumulated material may be selectively actuated by the control unit. For example, if the material is accumulated only at a portion of wall of the vehicle structure (210), the panels (10) mounted to the walls only can be activated to dislodge the accumulated material. Similarly, if the material is accumulated only to the base of the vehicle structure (210), then the panel (10) associated to the base can be activated to dislodge the accumulated material.

Initially, the vehicle structure (210) is tilted from a first position (FP) to the second position (SP), i.e., from a lower position to an elevated position at a predetermined angle using a tilting mechanism. Later, one or more sensors are configured to determine the material accumulated on a surface of the vehicle structure (210) and generate at least one a signal. The one or more sensors are provided on the frame (10a) of at least one apparatus (100) to dislodge the accumulated material. The control unit in fluid communication with acoustic generator is selectively actuated to generate and supply radiating acoustic wave pulses, to acoustic emitters (30) mounted to the frame (10a). The radiated acoustic wave pulses in conjunction with pressurized fluid, impacts the surface of the vehicle structure (210) and dislodges the material accumulated on the frame (10a) due to continuous vibrations.

In an embodiment, the apparatus (100) according to present disclosure provides a cost-effective solution for dislodging accumulated material from the surface of the vehicle structure (210).
In an embodiment, the size, configuration of the components of apparatus (100) may be varied according to the application requirement.
In an embodiment, the present disclosure provides the apparatus (100) that is simple, robust, and compact.
In an embodiment, the apparatus (100) of the present disclosure eliminates need of frequent maintenance of the vehicle structure (210) due to accumulation of types of material and protects the vehicle structure (210) from further damage due to ambient conditions [such as corrosion, erosion etc.,] as the material is completely removed from the vehicle structure (210).
In an embodiment, the apparatus (100) of the present disclosure employs the acoustic emitters (30) and pressurized fluid to dislodge the material which reduces unloading time of the material from the vehicle structure (210) at reduced tilting/ tipping angles of the vehicle structure (210).

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.).
