Description:FIELD OF THE INVENTION

[0001] The present invention relates to an automated organic fertilizer spreading device for agricultural fields that is capable of assessing soil condition of an agricultural field to prepare organic fertilizer that enhances soil quality for improved plant cultivation and features a facility for automatically spreading fertilizer within the user-defined perimeter of the field along with ability to create furrows in the soil, ensuring the optimal distribution of fertilizers for effective soil enhancement.

BACKGROUND OF THE INVENTION

[0002] Spreading fertilizer over soil is an essential agricultural practice aimed at enhancing soil fertility and promoting healthy plant growth. Fertilizers provide vital nutrients such as nitrogen, phosphorus, and potassium, which are critical for plants' metabolic processes, including photosynthesis, root development, and overall plant health. Over time, soils can become depleted of these essential nutrients due to repeated cropping, erosion, and leaching. Without replenishment, soil quality deteriorates, leading to lower yields and poor plant health. Fertilizing the soil ensures that plants receive a consistent supply of nutrients, improving their growth rate, resistance to disease, and overall productivity. Moreover, the effective distribution of fertilizers is crucial. Uneven application can lead to nutrient imbalances, where certain areas of the field may receive too much fertilizer, causing plant toxicity or nutrient runoff, while other areas may be under-fertilized, resulting in poor growth. Spreading fertilizers evenly across the soil helps optimize nutrient uptake by plants and prevents wastage. Automated systems for fertilizer distribution have become increasingly important in modern agriculture, as they provide precise, efficient, and uniform application, minimizing human error, labor costs, and environmental impact. These systems also allow farmers to target specific areas in need of nutrients, ensuring more sustainable and productive agricultural practices.

[0003] Fertilizer spreaders are essential agricultural equipment used to evenly distribute fertilizers over soil to enhance crop growth. There are several types of fertilizer spreaders, including broadcast spreaders, drop spreaders, and liquid sprayers. Broadcast spreaders scatter fertilizer in a wide pattern across the soil, while drop spreaders release fertilizer in a more precise manner directly beneath the machine. Liquid sprayers are used for applying liquid fertilizers and can cover large areas quickly. These machines can be manual, tractor-mounted, or self-propelled, depending on the scale of operation. Despite their usefulness, these spreaders have several drawbacks. Broadcast spreaders, while efficient for large areas, can lead to uneven fertilizer distribution, causing areas of over-fertilization and under-fertilization, which can harm plant growth and pollute the environment. Drop spreaders provide more accuracy but are slower and require more labor-intensive operation for large fields. Liquid sprayers, though precise, can be expensive and require proper calibration to avoid wastage or inconsistent application. Moreover, improper handling and over-application can cause runoff, contaminating water sources. Furthermore, all types of spreaders require regular maintenance to ensure they function properly, and they may not be suitable for uneven or narrow areas, limiting their versatility in certain agricultural settings.

[0004] US3749321A discloses a fertilizer spreading mechanism in the rear portion of a vehicle body. A scraper belt on the floor of the vehicle conveys fertilizer in incremental steps towards a pair of helical rollers which are rotatably mounted on vertically disposed axes. The rollers spread the fertilizer conveyed to the rear of the vehicle by the scraper belt. The helical rollers are provided with a plurality of teeth on the edges thereof which disengage the fertilizer from the mass in the vehicle. The mechanism spreads the fertilizer alternately towards and away from each of the rollers by means of oscillating members located between and/or on both sides of the spreading rollers.

[0005] CN201846601U discloses a fertilizer spreading device belonging to an agricultural implement, which mainly solves the problem that as fertilizers are directly fetched by hands in general during spreading, the hands are easily hurt. The fertilizer spreading device comprises a handle and a fertilizer barrel, wherein the fertilizer barrel is fixed at the tail end of the handle, and the top end of the handle is also provided with a rubber sleeve; the bottom of the fertilizer barrel is provided with a plurality of small holes and also provided with a turntable which is fixed at the bottom of the fertilizer barrel through a shaft, through holes corresponding to the small holes at the bottom of the fertilizer barrel are arranged on the turntable, and the top of the fertilizer barrel is provided with an end cover, and one end of the end cover is fixed on the fertilizer barrel through a hinge. As a plurality of small holes are arranged on the fertilizer barrel, fertilizers can be conveniently spread, and due to the turntable at the bottom of the barrel, the fertilizer spreading device solves the problem of controlling the spreading amount of the fertilizers and is very convenient to use.

[0006] Conventionally, many devices have been developed to spread fertilizer in soil of a field, however these existing devices mentioned in the prior arts have limitations pertaining to preparation of organic fertilizer in accordance to soil condition of the field and optimal distribution over the soil for maximum soil benefit.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of evaluating soil conditions of an agricultural field and, in response, to prepare organic fertilizer to improve soil quality and support better plant growth. In addition, the developed device also needs to feature automatic distribution of the fertilizer across the field as per the user-defined boundaries and also should be capable of creating furrows in the soil to facilitate even application and integration of fertilizers for enhanced soil health.

[0022] Referring to Figure 1, an isometric view of an automated organic fertilizer spreading device for agricultural fields is illustrated, comprises of a cuboidal body 101 housed with a plurality of chambers 102, a plate 103 installed with the body 101 via an L-shaped telescopically operated rod 104 and equipped with plurality of primary pins 105, a sensing module 106 equipped with the pins, a motorized iris lid 107 configured with each of the chambers 102, a mesh 108 equipped in a rectangular member 109 positioned on a cylindrical container 110, placed underneath the chambers 102, a plurality of pneumatic pushers 111 configured with the member 109, a plurality of motorized sliders 112 installed between the member 109 and pins, a motorized stirrer 113 configured in the container 110, a platform 114 attached with the body 101 and equipped with a motorized disc 115, an electric pump 116 configured with the container 110.

[0023] Figure 1 further illustrates a conduit connected with the pump 116 and the disc, plurality of motorized omnidirectional wheels 117 configured underneath the body 101, an elongated structure 118 configured with the body 101 via an L-shaped telescopically operated bar 119 and equipped with plurality of secondary pins 120, an AI-based imaging unit 121 mounted within the body 101, a pair of robotic arms 122 assembled in the body 101, a vessel 123 arranged in the body 101, an electronic nozzle 124 configured with the container 110, a receptacle 125 connected with the nozzle 124, a motorized blade 126 configured with the member 109, a vibrating unit 127 configured with the mesh 108, and a Peltier unit 128 configured with the container 110.

[0024] The present invention includes a body 101 preferably in portable cuboidal shape incorporating various components associated with the device, developed to be positioned on an agricultural field. The bottom portion of the body 101 is configured with plurality of motorized omnidirectional wheels 117 for maneuvering the body 101 over the field as per requirement. The body 101 is equipped with a plurality of chambers 102. Different type of manures and biodegradable materials are stored within the chambers 102 for preparing of fertilizer for the field. The different type of manures includes, but not limited to cow dung, poultry manure, while the biodegradable materials include, but not limited to wheat straw, green waste and egg shells.

[0025] A user is required to access and presses a push button arranged on the body 101 to activate the device for associated processes of the device. The push button when pressed by the user, closes an electrical circuit and allows currents to flow for powering an associated microcontroller of the device for operating of all the linked components for performing their respective functions upon actuation. The microcontroller, mentioned herein, is preferably an Arduino microcontroller. The Arduino microcontroller used herein controls the overall functionality of the linked components.

[0026] After the activation of the device, the user accesses a user interface which is installed in a computing unit linked with the microcontroller wirelessly by means of a communication module. The user interface enables the user to provide input regarding preparing and spreading of organic fertilizer in the field, along with selecting perimeter of the field. The communication module includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The Wi-Fi module contains transmitters and receivers that use radio frequency signals to transmit data wirelessly to the microcontroller. The wireless module typically includes components such as antennas, amplifiers, and processors to facilitate communication and further connected to networks such as Wi-Fi, Bluetooth, or cellular networks, allowing devices to exchange information over short or long distances for communication of wireless commands to facilitate operations of the device.

[0027] Upon receiving of the user input, the microcontroller generates a command to activate an artificial intelligence-based imaging unit 121 integrated on the body 101 for capturing multiple images in a vicinity of the field to generate a 3-dimensional (3D) map of surrounding of the field. The imaging unit 121 incorporates a processor that is encrypted with an artificial intelligence protocol. The artificial intelligence protocol operates by following a set of predefined instructions to process data and perform tasks autonomously. Initially, data is collected and input into a database, which then employs protocol to analyze and interpret the captured images. The processor of the imaging unit 121 via the artificial intelligence protocol processes the captured images and sent the signal to the microcontroller.

[0028] The evaluated 3-dimensional map of the surrounding of the field is displayed over the computing unit to enable the user for providing input selection of the perimeter of the field for spreading of fertilizer. A GPS (Global Positioning System) module is integrated within the microcontroller for detecting real-time location of the body 101. The GPS (Global Positioning System) module working in sync with a magnetometer provides enhanced positioning and orientation information of the body 101. The GPS module receives signals from multiple satellites in orbit around the Earth. These satellites transmit precise timing and position information of the body 101. The GPS module receives these signals and uses the time delay between transmission and reception to calculate the distance between the GPS module and each satellite. By triangulating the distances from multiple satellites, the GPS module determines its own position on the Earth's surface. This position is typically given in latitude and longitude coordinates.

[0029] The magnetometer of the GPS module measures the strength and direction of the magnetic field in its vicinity. The magnetometer detects the Earth's magnetic field, which is approximately aligned with the Earth's geographic north-south axis. By utilizing the magnetometer's measurements, the GPS module determine the band heading or orientation relative to magnetic north. The magnetometer provides information about the direction of the Earth's magnetic field, which is compared with the band position information obtained from the GPS module. The outputs of the GPS module and the magnetometer are combined and processed by the microcontroller in order to determine the location of the body 101.

[0030] In accordance to the detected location of the body 101 and the user defined perimeter, the microcontroller then powers an associated direct current (DC) motor connected with the wheels 117, in sync with the imaging unit 121. The wheels 117 have small discs or rollers around the circumference of the wheel that are powered by the motor, enabling the wheels 117 to move in required direction, which provide the body 101 with the required movement for maneuvering over the field within the user-selected perimeter, in a sequential manner.

[0031] An L-shaped telescopically operated rod 104 is configured with the body 101. The rod 104 is integrated with a plate 103 as an end effector. A pneumatic arrangement is associated with the device for providing extension/retraction of the rod 104 as per requirement. The plate 103 is integrated with plurality of primary pins 105 suspending vertically downwards form the plate 103. The ends of the primary pins 105 are equipped with a sensing module 106.

[0032] During the maneuvering over different locations of the field, the microcontroller actuates an air compressor and air valve associated with the pneumatic arrangement consisting of an air cylinder, air valve and piston which works in collaboration to aid in extension and retraction of the rod 104. The air valve allows entry/exit of compressed air from the compressor. Then, the valve opens and the compressed air enters inside the cylinder thereby increasing the air pressure of the cylinder. The piston is connected to the rod 104 and due to the increase in the air pressure, the piston extends. For the retraction of the piston, air is released from the cylinder to the air compressor via the valve. Thus, providing the required extension/retraction of the rod 104 for positioning and inserting the pins into the soil for soil analysis by the sensing module 106 to monitor condition of the soil. All the pneumatically operated components associated with the device comprises of the same type of pneumatic arrangement.

[0033] The sensing module 106 includes a first moisture sensor, pH sensor, NPK sensor, and salinity sensor for detecting moisture level, pH, nutrient level, and salinity level of the soil. The first moisture sensor of the sensing module 106, detects the moisture content of the soil, ensuring the soil is neither too dry nor overly saturated, thus aiding in maintaining optimal soil conditions for plant growth.

[0034] Additionally, the pH sensor measures the acidity or alkalinity of the soil, providing valuable data to determine whether the soil's pH is within the suitable range for cultivation of plants. The NPK sensor assesses the levels of essential nutrients in the soil, specifically nitrogen (N), phosphorus (P), and potassium (K), which are vital for plant health and growth. This helps in determining whether any nutrient deficiencies exist, allowing for precise adjustments in fertilizer application. Lastly, the salinity sensor measures the salt concentration in the soil, which is important for ensuring that the soil remains within the ideal salinity range to prevent damage to plants.

[0035] The microcontroller evaluates the collected data of the sensing module 106 to determine type of the manures and biodegradable materials along with the quantity to be used for preparing organic fertilizer, in view of improving overall soil health and crop yield.

[0036] In accordance to prepare fertilizer as per the detected soil condition, the different type of manures and biodegradable materials are required to be mixed to form customized organic fertilizer for improving the soil condition. The bottom portion of each of the chambers 102, is integrated with a motorized iris lid 107 for dispensing materials over a rectangular member 109 positioned on a cylindrical container 110, placed underneath the chambers 102.

[0037] The microcontroller actuates the iris lids 107 of respective chamber 102 to dispense evaluated amount of manure and biodegradable materials over the member 109. Each of the motorized iris lid, mentioned herein, consists of a ring in bottom configured with multiple slots along periphery, multiple number of blades and blade actuating ring on the top. The blades are pivotally jointed with blade actuating ring and the base plate 103 are hooked over the blade. The blade actuating ring is rotated clock and antilock wise by a DC motor embedded in ball actuating ring which results in opening of the holes to dispense evaluated amount of manure and materials for fertilizer making over the member 109.

[0038] The member 109 is equipped with a mesh 108 for filtering content to sieve into the container 110. The periphery portion of the member 109 is arranged with multiple motorized sliders 112. Multiple pneumatic pushers 111 are configured with the member 109 via the sliders 112. The extension/retraction of the pushers 111, is powered by the pneumatic arrangement. The working of the extension/retraction of the pushers 111 is similar to the working of the rod 104 as mentioned above.

[0039] The dispensed manure and the materials are in form of large chunks. The microcontroller actuates the pushers 111 via the pneumatic arrangement to work in conjunction with the motorized sliders 112 for breaking large chunks of manure and biodegradable material into fine particles. The smaller particles facilitate in easy mixing to form a uniform fertilizer.

[0040] Each of the slider 112 is associated with a pair of sliding rails fabricated with grooves in which the wheel of the slider 112 is positioned that is further connected with a bi-directional motor via a shaft. The microcontroller actuates the bi-directional motor to rotate in a clockwise and anti-clockwise direction that aids in the rotation of the shaft, wherein the shaft converts the electrical energy into rotational energy for allowing movement of the wheel to translate over the sliding rail by a firm grip on the grooves. The movement of the slider 112 results in the translation of the pushers 111 over the mesh 108 for providing required to-and-fro movement to the pushers 111 in view of breaking large chunks of manure and biodegradable material into fine particles.

[0041] The fine particles, post breaking of chunks, are sieved through the mesh 108 plate 103 into the container 110 by means of the activation of a vibrating unit 127 configured with the mesh 108. The vibrating unit 127 subjects the mesh 108 to the action of moving or causing to move back and forth or from side to side very quickly leading to controlled and reproducible mechanical vibration. The produced vibrations result in providing vibrations to facilitate in sieving of the manure and biodegradable materials.

[0042] In case green waste like leaves are required to be chopped, the microcontroller actuates a motorized blade 126 configured with the member 109 for chopping green waste like leaves. The blade 126 is attached with the member 109 by means of a hinge joint. The microcontroller actuates a direct current (DC) motor associated with the hinge joint such that tilt the blade 126 by revolving along the longitudinal axis. The tilting movement of the blade 126 chops the dispensed green waste for preparing the organic mix of fertilizer.

[0043] The microcontroller via the imaging unit 121 detects presence of unwanted materials including plastic, metal, on the mesh 108. In case the microcontroller detects presence of unwanted materials, the microcontroller actuates a pair of robotic arms 122 assembled in the body 101 for collecting the unwanted materials.

[0044] Each of the robotic arm 122 comprises, motor controllers, arm 122, end effector and sensors. All these parts are configured with the microcontroller. The elbow is at the middle section of the arm 122 that allows the upper part of the arm 122 to move the lower section independently. Lastly, the wrist is at the tip of the upper arm 122 and attached to the end effector thereby the end effector works as a hand to collect and discard the unwanted materials in a vessel 123 arranged in the body 101.

[0045] Post collection of the fine particles into the container 110, the microcontroller actuates a motorized stirrer 113 configured in the container 110 for mixing the manure with the biodegradable materials to obtain the organic fertilizer. The motorized stirrer 113 comprises a rod that is configured with multiple propellers. The rod is rotated by the means of a DC (Direct Current) electric motor in order to provide motion to the propeller to mix up the ingredients of the fertilizer and create a homogeneous mixture.

[0046] The container 110 is embedded with a secondary moisture sensor for detecting level of the fertilizer. The working of the secondary moisture sensor is similar to the working of the primary moisture sensor as mentioned above, to enable the microcontroller to determine moisture content in the prepared fertilizer.

[0047] The container 110 is integrated with a receptacle 125 for storing water. In case the microcontroller evaluates the detected level of moisture recedes a threshold value pre-fed in the linked database, the microcontroller actuates an electronic nozzle 124 configured with the receptacle 125 for dispensing water into the container 110 for maintain moisture level in the prepared fertilizer.

[0048] The electronic nozzle 124, used herein, is a short tube with a taper integrated with fine-tuned valve or orifice that is electronically regulated to speed up or regulate the flow of the water. The valve controls flow of the water by varying the size of the flow passage as directed by a signal from the microcontroller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, and water level in view of dispensing the water as per the determined requirement to maintain moisture of the prepared fertilizer.

[0049] The temperature of the prepared fertilizer is monitored by a temperature sensor embedded in the container 110. The temperature sensor used herein, is composed of two type of metal wire joint together when the sensor experiences a heat then a voltage is generated in the two terminal of the temperature sensor that is proportional to the temperature and the signal is sent to the microcontroller. The microcontroller calibrates the voltage in terms of temperature from the received signal of the temperature sensor in order to monitor the temperature of the fertilizer of the container 110.

[0050] The microcontroller evaluates the detected temperature of the prepared fertilizer mismatches with a threshold value pre-fed in the linked database, the microcontroller actuates a Peltier unit 128 configured with the container 110 for maintaining temperature of the fertilizer. The Peltier unit 128 is based on the Peltier effect that stated that the cooling of one junction and the heating of the other when electric current is maintained in a circuit of material consisting of two dissimilar conductors. The Peltier effect related to production or absorption of heat at the junction of two metals on the passage of a current, thereby providing heating/cooling effect to maintain an optimum temperature of the organic fertilizer as per the detected condition of soil.

[0051] A platform 114 is attached with the body 101 and equipped with a motorized disc. The container 110 is connected with the disc 115 via a conduit. An electric pump 116 is configured with the container 110 for transferring the organic fertilizer over the disc 115 via the conduit connected with the pump 116.

[0052] Post preparation of the organic fertilizer, the microcontroller activated the pump 116 to transfer the content of the container 110 to the disc. The electric pump 116 is used to induce flow or raise the pressure of the fertilizer. The working principle of pump 116 involves imparting energy to the fertilizer by means of a centrifugal force developed by the rotation of an impeller that has several blades or vanes. The impeller of the pump 116 is rotated by an electric DC (Direct Current) motor. The fertilizer in the specified portion enters the impeller’s eye and translates through the outlet conduit to the disc 115 in order to spread the fertilizer in the user-specified perimeter of the field.

[0053] Synchronously, the microcontroller actuates a direct current (DC) motor associated with the disc 115 such that rotates an integrated hub of the disc. The rotation of the hub of the disc 115 consequently results in rotation of the disc 115 for applying for spreading the fertilizer on the soil. The peripheral position of the disc 115 is equipped with wholes which directs the received fertilizer from the container 110 towards the soil. Simultaneously, the microcontroller regulates the actuation of the wheels 117 for maneuvering the body 101 under the specified perimeter, thereby spreading the fertilizer in the soil for improving the soil condition.

[0054] The body 101 is incorporated with an elongated structure 118 by means of an L-shaped telescopically operated bar 119. The extension/retraction of the bar 119 is powered by the pneumatic arrangement. The working of the extension/retraction of the bar 119 is similar to the working of the rod 104 as mentioned above. The microcontroller actuates the bar 119 via the pneumatic arrangement to position the structure 118 in contact with soil. The bottom portion of the structure 118 is integrated with plurality of secondary pins 120. During the movement of the body 101 on the field, the structure 118 via the secondary pins 120 creates furrows in the soil, in order to allow optimum distribution of the fertilizers within the soil.

[0055] A battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0056] The present invention works best in the following manner, where the cuboidal body 101 as disclosed in the invention is placed on the agricultural field, which houses several chambers 102 containing different types of manures and biodegradable materials. The body 101 is wirelessly linked to the user-interface embedded within the computing unit, allowing users to input commands to spread organic fertilizer and select the perimeter of the field. The plate 103 with primary pins 105, attached via the L-shaped telescopic rod 104, is extended into the soil by the microcontroller, enabling the sensing module 106 to monitor soil conditions. Based on this input, the microcontroller determines the appropriate types of manures and biodegradable materials to be used for fertilizer production. Each chamber 102 has the motorized iris lid 107 that opens to dispense the selected manures and biodegradable materials onto the mesh 108 positioned in the rectangular member 109 beneath the cylindrical container 110. The Pneumatic pushers 111 and motorized sliders 112 then break the material into fine particles, which are sieved through the mesh 108 and collected in the container 110. The motorized stirrer 113 mixes the materials to create the organic fertilizer.

[0057] In continuation, the fertilizer is transferred from the container 110 to the motorized disc, which spreads it onto the soil, while the GPS module guides motorized omnidirectional wheels 117 to move the device within the user-defined perimeter. Additionally, the device uses the L-shaped telescopic bar 119 with secondary pins 120 to create furrows in the soil for optimal fertilizer distribution. The sensing module 106 monitor moisture, pH, nutrient levels, and salinity, while the imaging detects and removes unwanted materials, ensuring high-quality fertilizer is used. The secondary moisture sensor and the Peltier unit 128 regulate the fertilizer temperature, and the member 109 also includes the motorized blade 126 for chopping green waste, the vibrating unit 127 to aid in sieving, while the nozzle 124 integrated with the body 101 to dispense water as needed for maintaining moisture content of the fertilizer.

[0058] Although the field of the invention has been described herein with limited reference to specific embodiments, this description is not meant to be construed in a limiting sense.
