Description:FIELD OF THE INVENTION

[0001] The present invention relates to a system for targeted agricultural resource dispensing for crop plantations that enables automatic detection of soil conditions, in order to identify the specific requirements of crops, which helps to ensure that the right type and amount of nutrients are delivered where needed.

BACKGROUND OF THE INVENTION

[0002] In traditional agricultural practices, farmers often apply water, fertilizers, and other resources uniformly across entire fields without considering the specific needs of different crop areas. This approach leads to inefficient use of resources, increased operational costs, and potential environmental harm due to over-application. Moreover, variations in soil composition, moisture levels, and nutrient deficiencies across different parts of the field are often overlooked, resulting in uneven crop growth and reduced yield. Manual monitoring and dispensing are labor-intensive, time-consuming, and prone to human error. These challenges highlight the need for a system that detect localized soil conditions and deliver precise amounts of agricultural resources to targeted crop areas, ensuring optimal crop health and sustainable farming practices.

[0003] Existing agricultural devices, such as automated sprayers, drip irrigation systems, and drone-based monitoring tools, offer some level of precision in resource application. However, most of these systems lack the capability to analyze real-time soil conditions at the micro-level for individual crops. They typically rely on pre-set schedules or generalized field data, which do not reflect localized variations. Many devices are limited to either irrigation or fertilization, without integration for both, and require significant manual intervention for adjustments. Additionally, some systems are costly, complex to operate, or not scalable for small to medium-sized farms. These limitations reduce overall efficiency, increase resource wastage, and fail to ensure crop-specific enrichment tailored to the actual needs of each plant.

[0019] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a system for targeted agricultural resource dispensing for crop plantations that ensures timely and efficient placement of nutrients and moisture agents in the soil to support improved crop growth. In addition, the system disclosed herein helps to maintain optimal growing environments, enhancing crop yield while minimizing resource waste and reducing the need for manual intervention.

[0022] Referring to Figure 1, an isometric view of a system for targeted agricultural resource dispensing for crop plantations is illustrated, comprising a body 101 designed to house multiple chambers 102, a plurality of legs 103 attached with a motorized wheel 104 is installed underneath the body 101, a container 105 located beneath the chambers 102 and equipped with a suction unit 106, a mixer 107 is mounted on an inner wall of the container 105, a motorized slidable flap 108 mounted underneath the container 105, a primary conveyer belt 109 attached with the container 105, a compartment 110 positioned at a lower end of the primary conveyer belt 109, a motorized iris lids 111 carved onto a base portion of the compartment 110, a hydraulic ram 112 mounted on a ceiling portion of the body 101.

[0023] Figure 1 further illustrates, a blade 113 is installed underneath the compartment 110 by means of an extendable shaft 114, a secondary conveyer belt 115 is arranged underneath the compartment 110, a receptacle 116 arranged on a base portion of the body 101, a (Selective Compliance Articulated Robot Arm) SCARA 117 is installed on the body 101, a hollow cylindrical duct 118 is attached with the body 101 and linked with a vessel 119, a motorized iris operated lid 120 is installed at a lower side of the vessel 119, an electronically controlled nozzle 121 is mounted on a lower portion of the body 101, a multi-sectioned vessel 122 is configured with the nozzle 121, an air blower 123 is disposed along length of the second conveyer belt and a speaker 124 is mounted on the body 101.

[0024] The system disclosed in the present invention comprises of a body 101 configured to house multiple chambers 102 for storing various raw materials, with a plurality of legs 103 installed underneath and each leg equipped with a motorized wheel 104, enabling the body 101 to remain stable and navigate efficiently across the ground surface of an agricultural field for effective material transport and field operation.

[0025] To activate the system, the user manually presses a push button which is installed on the body 101. Upon pressing the button, the circuits within the system gets close, allowing electric current to flow. The push button has an outer casing and an inner mechanism, including a spring and metal contacts. When the button is pressed, the spring-loaded mechanism inside is pushes down on. In the default state, the internal contacts are apart, so the circuit is open and no electricity flows. Pressing the button makes the contacts touch each other, closing the circuit and allowing electricity to flow, which activates an inbuilt microcontroller that regulates the further options of the system.

[0026] Upon activation of the system, the microcontroller activates an inbuilt communication module for establishing a wireless connection between the microcontroller and a computing unit that is inbuilt with a user-interface and accessed by the user for enabling the user to give input commands regarding soil enrichment for a specific crop type and the location of the crop. The user interacts with the interface through a touch screen, keyboard, or other input methods available on the computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet.

[0027] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the system is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data exchange, interfaces with microcontrollers through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity.

[0028] Based on the input commands from the user, the microcontroller access a database linked to a processing unit of the computing in order to detect the exact location of the crop. Upon detecting the location of the crop, the microcontroller activates a GPS (Global Positioning module) installed on the body 101 for tracking real-time location of the body 101. The GPS module receives signals from multiple satellites in the GPS constellation. Each satellite transmits a signal that includes the position of the body 101 and the precise time of the signal. The GPS module uses these signals to calculate the distance from each satellite based on the time it took for the signal to reach the module. By receiving signals from multiple satellites, the module performs trilateration and calculates the exact position (latitude, longitude, and altitude) of the body 101. The microcontroller receives the GPS coordinates and process them as needed.

[0029] In case, the location of the body 101 is detected to be far away from the crop, the motorized wheels 104 are actuated by the microcontroller for translating the body 101 in proximity of the crop. The motorized wheels 104 function by using the rotational power of a DC motor to drive the rollers of the wheel 104, which are positioned at a 45-degree angle to the central axis of the wheel 104. As the DC motor rotates the wheel 104, each roller moves independently to generate forces in multiple directions. The combination of these forces allows the wheel 104 to move the body 101 smoothly in any direction, including forward, backward, or sideways, without changing the orientation of the wheels 104.

[0030] As the body 101 is positioned in close proximity of the crop, the microcontroller activates a sensing module including a soil pH sensor, a moisture sensors and a nutrient detection sensors (NPK), installed in the wheels 104 for detecting quality of soil in close proximity to the specified crop. The soil pH sensor measures the hydrogen ion concentration in the soil to determine its pH level using two electrodes to create an electrical circuit. The sensing electrode contains a substance with a known electric potential which is inserted into the soil that is being tested. The measuring electrode is made of a pH-sensitive glass that reacts to the hydrogen ion concentration in the soil. The glass membrane's buffer solution allows hydrogen ions to enter the membrane, creating a voltage potential that is measured by the sensor to calculate the pH value of the soil.

[0031] The nutrient detection sensors operate by identifying the concentration of Nitrogen, Phosphorus, and Potassium in the soil through chemical or electrical interactions with soil ions. Ion-selective electrodes embedded in the sensors are sensitive to specific ions—Nitrate (NO₃⁻), Phosphate (PO₄³⁻), and Potassium (K⁺). When these sensors come in contact with the soil, the target ions interact with their respective electrodes, generating electrical signals proportional to their concentration. These signals are transmitted to a processing unit, which uses calibration data to convert the signals into nutrient level readings.

[0032] The determined data from the sensing module is sent to the microcontroller, where the data is compared with a pre-saved data about quality of the soil, in a database. Based on which the microcontroller evaluates an appropriate amount of raw materials required to form pallets.

[0033] Based on the required amount of raw material to form pallets, a suction unit 106 is actuated by the microcontroller to extract the evaluated amount of raw material from the chambers 102. The suction unit 106 consists of a pump that operates by creating a vacuum to draw raw material from the chambers 102. When the pump is activated, it draws the air in through an intake. Inside the pump, a rotating impeller moves to reduce the pressure within the pump chamber. This reduction in pressure creates a vacuum effect, which generates suction and draw the raw material from the chambers 102.

[0034] The drawn raw material is transferred to a container 105 arranged in the body 101, located beneath the chambers 102 through a plurality of conduit connected to each chamber. As the raw material is dispensed in the container 105, the microcontroller actuates a mixer 107 mounted on an inner wall of the container 105 for blending the dispended materials to form a mixture of optimal consistency. The mixer 107 operates by using an electric motor to drive a rotating shaft 114, which is equipped with a paddle. The motor's rotational force is transmitted through the shaft 114 to the paddle, which grinds the raw material for forming the mixture.

[0035] Upon successful blending of the raw material, the microcontroller activates a motorized slidable flap 108 mounted underneath the container 105 to get translated for opening the container 105 to dispense the blended mixture. The slideable flap 108 consist of a sliding rail and a motorized slidable member connected to the sliding rail. The motorized slidable member is attached to the flap 108 and sliding rail on both sides to make the flap 108 slide. The slidable member is attached to a motor which provides movement to the flap 108 in a bi-directional manner in order to open the container 105 in order to dispense the mixture over a primary conveyer belt 109 attached with the container 105.

[0036] The primary conveyer belt 109 is equipped with a plurality of touch sensors to detect the presence of the mixture over the primary conveyer belt 109. The touch sensor consists of a conductive surface connected to an electronic circuit that measures the change in capacitance. When the conductive surface comes in contact with the mixture, the capacitance in the electric circuit changes, and a signal is generated that reflect the presence of the mixture over the primary conveyer belt 109.

[0037] Based on the detected presence of the mixture, the primary belt 109 is actuated by the microcontroller for translating the mixture towards a compartment 110 positioned at a lower end of the primary conveyer belt 109. The primary conveyor belt works by using two motorized pulleys that loop over a long stretch of thick and durable material. The motor drives the pulley at the same speed and spin in the same. As the pulley turns, it pulls the belt along its path. The belt moves over a series of rollers, which reduce friction and support the belt. As the belt moves, the mixture over the primary belt 109 is transported towards the compartment 110.

[0038] In synchronization with the primary belt 109, a plurality of motorized iris lids 111 with a plurality of holed, carved onto a base portion of the compartment 110 is actuated by the microcontroller for adjusting size of the hole as per a pre-defined size of pellets. The iris lid 111 is an adjusting circular aperture comprised of an actuation ring and a plurality of blades according to the size of the lid 111. The blades are engraved with the protrusions through which the actuation ring is affixed to each blade. The actuation ring is connected to a control arrangement, such as a motor, which helps in the movement of the actuation ring leading to the movement of blades inward or outward to change the size of the opening. When the blades close, the aperture becomes smaller, closing the lid 111. When the blades open, the aperture widens, opening the lid 111. The adjustment of the blades allows the iris lid 111 to control the dispensing of the mixture through the holes.

[0039] As the lids 111 are opened, a hydraulic ram 112 mounted on a ceiling portion of the body 101 is actuated by the microcontroller to apply a compressive force upon the mixture for extruding the mixture through the iris holes, to form elongated tubes. The hydraulic ram 112 extend / retract through a hydraulic pump in which fluid moves from a reservoir into the hydraulic cylinder. The hydraulic cylinder is a sealed tube with a piston inside. When the pump sends fluid into the cylinder, it fills one side of the piston. The fluid pressure pushes against the piston, causing it to move. Because the piston is attached to the hydraulic ram 112, this movement extends the ram 112 outward from the cylinder. The ram 112 continues to extend as long as fluid is being pumped into the cylinder. When the ram 112 reaches the desired height, the pump stops, and the fluid remain in the cylinder for holding the ram 112 in place. To retract the ram 112, the hydraulic fluid is directed out of the cylinder and back to the reservoir. This causes the piston to move back into the cylinder, retracting the ram 112. This way the ram 112 extends/retracts to push the mixture.

[0040] Upon pushing the mixture through the holes in the form of tubes, an extendable shaft 114 is actuated to extend a blade 113 installed with the shaft 114 for cutting the tubes in the required pellet forms. The shaft 114 is powered through the hydraulic pump associated with the system. The extension/retraction of the shaft 114 works in the similar manner as mentioned above. As the blade 113 is extended a gear rack assembly integrated with the blade 113 is actuated by the microcontroller to provide controlled movement to the blade 113 for cutting the tubes.

[0041] The gear rack assembly converts rotational motion into linear motion using two main components: a pinion gear and a linear rack. The rack is a straight bar with evenly spaced teeth, while the pinion is a circular gear that meshes with these teeth. When the pinion rotates, its teeth push against the teeth on the rack, causing the rack to move in a straight line. The direction of the pinion's rotation determines the direction of the rack’s movement clockwise for forward and counterclockwise for backward. The assembly provides smooth, controlled back-and-forth motion, making the it ideal for moving blade 113 for cutting.

[0042] The formed pallets are dispended on a secondary conveyer belt 115 arranged underneath the compartment 110, which is actuated by the microcontroller for translating the pellets towards a receptacle 116 arranged on a base portion of the body 101. The secondary conveyer belt 115 work in the similar manner as mentioned above.

[0043] Upon dispensing the pellets over the secondary conveyer belt 115, the microcontroller actuates an air blower 123 coupled with a temperature sensor, disposed along length of the second conveyer belt to blow air onto the formed pellets. The air blower 123 works by using a motor to drive a fan, which generates a flow of air. The motor is typically powered by electricity and is connected to a fan blade that spins at high speed. As the fan blades rotate, they create a pressure difference that pulls air into the blower 123 and forces the pulled air out through an outlet. The direction and intensity of the airflow is controlled by the microcontroller.

[0044] In synchronization with the temperature sensor, the microcontroller activates the temperature sensor to monitor the temperature of the pellets. The temperature sensor operates by using a temperature-sensitive element, such as Resistance Temperature Detector (RTD), which changes its electrical resistance with temperature variations. As the temperature rises or falls, the resistance of the element changes accordingly. This change in resistance is converted into an electrical signal by the sensor's circuitry, which then processes the signal to determine the temperature. Based on the detected temperature the microcontroller regulates the actuation of the air blower 123 to maintain the consistency of the pellets.

[0045] As the pellets are translated in the receptacle 116, a motorized hinged door associated with the receptacle 116 is for opening and allowing easy access to the collected pellets. The motorized hinged door typically involves the use of an electric motor to control the movement of the door. The hinge provides the pivot point around which the movement of the door occurs. The motor is the core component responsible for generating the rotational motion. The motor converts the electrical energy into mechanical energy, producing the necessary torque that drives the hinge. As the motor rotates, the hinge orients the door to open.

[0046] Upon opening the door, the microcontroller actuates a (Selective Compliance Articulated Robot Arm) SCARA 117 installed on the body 101, in close proximity to the receptacle 116 for collecting and positing the pellets in the soil. The (Selective Compliance Articulated Robot Arm) SCARA 117 consists of two parallel rotary joints that provide compliance in the X-Y plane but rigid vertical (Z-axis) movement. The arm has a base that allows rotational motion, followed by a second rotating link, enabling the end effector to reach various positions within its working envelope. A vertical linear actuator moves the arm up and down for Z-axis operations.

[0047] As the pellet is placed over the soil, a weight block is attached to the body 101 through an electromagnetic spring to apply pressure onto the weight block for pressing the pellet into the soil at an optimal depth. The electromagnetic spring consists of a coil of wire, a ferromagnetic core, and a mechanical spring. When an electric current flows through the coil, it creates a magnetic field around the coil. This magnetic field attracts the ferromagnetic core, pulling it towards the coil. The mechanical spring is connected to the core and positioned in such a manner that it either compresses or extends as the ferromagnetic core moves in response to the magnetic field. When the current is off, the magnetic field disappears and the spring returns the core to its original position due to its restoring force.

[0048] In case, the detected moisture of the soil recedes below a pre-defined threshold value, the microcontroller actuates a motorized iris operated lid 120 installed at a lower side of the receptacle 116 to dispense the hydrogel through a hollow cylindrical duct 118 attached with the body 101 into the soil. The motorized iris operated lid 120 work in the similar manner as mentioned above.

[0049] In case, the soil requires fertilization, an electronically controlled nozzle 121 mounted on a lower portion of the body 101 is activated by the microcontroller for spraying an optimum quantity of liquid fertilizers stored in a multi-sectioned vessel 122 onto the soil. The electronic nozzle 121 comprises of a gate and a magnetic coil which uses electricity from microcontroller to generate the force to control the opening/closing of gate to control the flow of the liquid fertilizer through a small aperture of the nozzle 121, allowing for precise control of the flow of the liquid fertilizer on the soil.

[0050] In order to notify the user regarding the operation of the system, a speaker 124 is mounted on the body 101 is actuated by the microcontroller for issuing audio alerts, guidance, or status updates to the user during operation. The speaker 124 works by converting the electrical signal into the audio signal. The speaker 124 consists of a cone known as a diaphragm attached to a coil-shaped wire placed between two magnets. When the electric signal is passed through the voice coil, a varying magnetic field is generated by the coil that interacts with the magnet causing the diaphragm to move back and forth. The movement of the diaphragm pushes and pulls air creating sound waves just like the electrical signal received and used to notify the user.

[0051] Moreover, a battery is associated with the system to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes known as a cathode and an anode. A voltage is generated between the anode and cathode via oxidation/reduction and thus produces the electrical energy to provide to the system.

[0052] The present invention, works best in the following manner, where the body 101 mounted on legs 103 with motorized wheels 104, enabling mobility across agricultural fields. Activation of the system begins with a push button that initiates internal circuitry and activates the communication module, preferably a Wi-Fi module, to establish wireless connectivity with the computing unit for receiving user commands on crop location and enrichment type. The GPS module detects the body’s position, and the motorized wheels 104 navigate the body 101 near the crop. Soil analysis is conducted using soil pH sensors, moisture sensors, and nutrient detection sensors (NPK) embedded in the wheels 104. The collected data is evaluated against stored soil quality data to determine the required raw material. The suction unit 106 extracts materials from the chambers 102, which are mixed in the container 105 by the mixer 107 to form a blend. The slidable flap 108 dispenses the blend onto the primary conveyor belt, which transfers the mixture to the compartment 110. Motorized iris lids 111 adjust hole sizes, and the hydraulic ram 112 compresses the mixture through the holes into tubes. The gear rack assembly guides the blade 113 to cut tubes into pellets. The secondary conveyor belt moves the pellets to the receptacle 116, where the SCARA 117 places them in soil. The electromagnetic spring presses the pellet, and additional systems manage hydrogel dispensing, fertilizer spraying, and speaker-based alerts.

[0053] 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.
