BACKGROUND OF THE INVENTION

[0002] The cotton industry has long relied on manual labor and basic machinery for the harvesting of cotton balls. This traditional process is often labor-intensive, time-consuming, and prone to inconsistencies in quality control. The sorting of harvested cotton based on key quality parameters such as fiber length, strength and micronaire reading typically requires additional steps that involve specialized equipment and skilled labor.

[0003] Furthermore, existing systems do not offer an efficient, automated solution for determining cotton grades, pricing, and providing users with a streamlined method for selecting cotton based on their desired quality. With the growing demand for precision and efficiency in the cotton harvesting process, there is a need for an innovative solution that automate both the harvesting and sorting process, while simultaneously providing real-time feedback on the quality of the cotton. This would allow for greater accuracy, reduced labor costs and an optimized approach to cotton harvesting.

[0004] CN201355934Y discloses about a machine for picking cotton, in particular to a cotton picker, wherein the front portion of a cotton-picking passage of a cotton picking head is provided with a cotton plant gathering machine, and the two sides of the cotton picking head are provided with cotton picking rollers, moreover, the cotton picking head is also provided with a transmission mechanism of the cotton picking rollers and a cotton conveying mechanism for conveying seed cotton. The cotton picker is characterized in that a plural of cotton picking rollers with picking spindles and vertical axis are evenly arranged at the periphery of the cotton picking rollers, the axis of the picking spindles is vertical to the axis of the cotton picking rollers and revolves around the axis of the cotton picking rollers, the picking spindle located at the side of the cotton picking passage and in cotton picking state rotates, other picking spindles are disengaged from a component which leads the picking spindle to rotate, and the motion form is realized by the transmission mechanism, furthermore, the cotton conveying mechanism is located at the outer side of the cotton picking rollers. The cotton picker based on the technical solution of the utility model is high in cotton picking efficiency, low in the percentage of the trash content of picked cotton, excellent in fireproof performance and compact in structure.

[0005] CN104871732A discloses about a cotton-picking device. The cotton-picking device comprises a cylindrical casing, wherein square openings are formed in front and back sides of the cylindrical casing respectively, a plurality of clamp mounting panels are mounted in the cylindrical casing, a plurality of clamps are mounted on each clamp mounting panel, a spring restraining device is also mounted in the cylindrical casing, and a power transmission device is connected onto the clamps to drive the clamps to rotate on the clamp mounting panels. The center of each clamp mounting panel is fixed on the fixing shaft, a circle of arc-shaped groove is formed in the surface of each round panel, two ends of each arc-shaped groove are connected through a vertical groove in the radius direction, and the clamps rotate along the corresponding grooves. During rotation of the clamps, springs of the clamps are gradually extended or contracted so as to control clamp plates to gradually open, due to the connection position of the two ends of each arc-shaped groove, the clamps can perform quick clamping and then gradually open to release cotton, the steps are sequentially repeated, the whole process from cotton picking to cotton releasing can be realized, and cotton picking and releasing integration is realized.

[0006] Conventionally, many devices have been developed to aid in the harvesting and processing of cotton, but these devices lack the capability to efficiently sort cotton based on quality parameters such as fiber length, strength, and micronaire reading. Most existing devices also fail to integrate an automated pricing means based on the selected cotton grade, leaving much of the process still reliant on manual effort and inconsistent results.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that not only requires to automate harvesting process, but also accurately sort cotton based on key quality parameters, including fiber length, strength and micronaire reading. Furthermore, the developed device needs to enable users to select cotton according to their desired grade with the price being determined based on the cotton grade chosen.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[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 cotton ball harvesting and dispensing device that is capable of harvesting cotton balls from a cotton field and sorting the cotton balls according to quality parameters such as fiber length, strength and micronaire reading for enabling a user to choose cotton based on their preferred grade with the price determined by the selected grade.

[0022] Referring to Figure 1, an isometric view of a cotton ball harvesting and dispensing device is illustrated, comprising a cuboidal housing 101 having four perpendicularly installed telescopic rods with motorized omnidirectional wheels at the ends, attached underneath the housing 101, a LIDAR (light detection and ranging) sensor 103 embedded in the housing 101, an articulated L-shaped telescopic link 104 disposed on the housing 101 and having a motorized cutting blade, a pair of articulated L-shaped telescopic grippers 105 incorporated on the housing 101, a chamber 106 disposed in the housing 101.

[0023] Figure 1 further illustrates an artificial intelligence-based imaging unit 107 installed on the housing 101, a robotic arm 108 mounted on the housing 101, a thermal camera 109 integrated on the housing 101, an articulated L-shaped telescopic bar 110 having a nozzle connected with a pesticide tank 111 provided in the housing 101, a touch enabled display unit 112 mounted on the housing 101, a sorter conveyor 113 disposed in the housing 101, a robotic link 115 located in the housing 101 and a Peltier unit 117 configured in the chamber 106.

[0024] The proposed device herein comprises of a cuboidal housing 101 developed to be positioned on a ground surface, particularly in a cotton field. The housing 101 is configured with four perpendicular telescopic rods 102 attached with motorized omnidirectional wheels for maneuvering the housing 101 on ground surface. The housing 101 is made up of but not limited to durable materials such as high-grade aluminum alloy, stainless steel or reinforced polymer composites. These materials ensure structural integrity, corrosion resistance and lightweight properties for ease of mobility.

[0025] A user is required to press a push button integrated with the device, such that when the user presses the push button, it initiates an electrical circuit mechanism. Inside the push button, there is a spring-loaded contact mechanism that, under normal circumstances, maintains an open circuit. When the button is pressed, it compresses the spring, causing the contacts to meet and complete the circuit. This closure then sends an electrical signal to an inbuilt microcontroller associated with the device to either power up or shut down. Conversely, releasing the button allows the spring to return to its original position, breaking the circuit and sending the signal to deactivate the device.

[0026] Upon activation, the microcontroller engages a LIDAR (Light Detection and Ranging) sensor 103 embedded in the housing 101 to scan the surrounding surface contours and identifies available pathways. The LIDAR sensor 103 include a laser emitter, a photodetector and a scanner. The laser emitter generates short pulses of light that travel to a target surface and reflect back. The photodetector captures these reflected pulses and measures the time of flight to calculate the distance to the target. The scanner, typically a rotating mirror or prism, directs the laser pulses across a wide area to capture a detailed map of the environment. The data is then sent to the microcontroller, which processes the information to detect surface contours and available pathways. Based on this data, the microcontroller actuates the telescopic rods 102 and motorized wheels, enabling the housing 101 to navigate across the terrain while effectively avoiding obstacle.

[0027] An artificial intelligence-based imaging unit 107 is installed on the housing 101 and operates in synchronization with a proximity sensor embedded within the housing 101 to identify the presence of a cotton plant near the housing 101. The imaging unit 107 comprises of an image capturing arrangement including a set of lenses that captures multiple images of the surroundings, and the captured images are stored within a memory of the imaging unit 107 in form of an optical data. The imaging unit 107 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller.

[0028] Simultaneously, the microcontroller activates the proximity sensor, which operates based on its core components, including an emitter, a receiver, and a signal processor. The emitter sends out electromagnetic waves, such as infrared or ultrasonic signals, toward the surrounding area. When these waves encounter an object, such as a cotton plant, they are reflected back to the receiver. The signal processor calculates the distance to the object based on the time it takes for the waves to return. The proximity sensor's output data, along with the processed optical data from the imaging unit 107, are synchronized and transmitted to the microcontroller. This combined information enables the microcontroller to accurately detect the presence and location of a cotton plant in proximity to the housing 101.

[0029] After the housing 101 is positioned in proximity to the cotton plant, the microcontroller activates an articulated L-shaped telescopic link 104 installed on the housing 101 and equipped with a motorized cutting blade to cut cotton balls from the plants. The telescopic link 104 is powered by a pneumatic unit, including an air compressor, air cylinders, air valves and piston which works in collaboration to aid in extension and retraction of the link 104. The pneumatic unit is operated by the microcontroller. Such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the link 104 and due to applied pressure, the link 104 extends and similarly, the microcontroller retracts the link 104 by closing the valve resulting in retraction of the piston. Thus, the microcontroller regulates the extension/retraction of the link 104 in order to position the cutting blade towards the plants.

[0030] The microcontroller then actuates the cutting blade to cut cotton balls from the plants. The blade is powered by a DC (direct current) motor that is capable of converting the electric current provided from an external force into mechanical force for providing the required power to the blade, thus cutting the cotton balls from cotton plants that is gripped by means of a pair of articulated L-shaped telescopic grippers 105 incorporated on the housing 101.

[0031] The telescopic gripper 105 is linked to a pneumatic unit, including an air compressor, air cylinders, air valves and piston which works in collaboration to aid in extension and retraction of the gripper 105 to grip the cotton plants during the cutting process. After the cotton balls are cut, the microcontroller actuates a robotic arm 108 mounted on the housing 101 to place the cotton ball in the chamber 106. The robotic arm 108 is able to perform the designated task with high efficiency and accuracy, wherein the robotic arm 108 consists of mechanical joints and actuators, which are controlled by the microcontroller. The actuators allow various degrees of freedom and movement and the joints are actuated by a DC (Direct Current) motor, providing the necessary force and motion to grip and place the cotton balls within the chamber 106.

[0032] A hyperspectral sensor is mounted on the housing 101 and operates in synchronization with a thermal camera 109 mounted on the housing 101 to detect cotton balls exhibiting defects, such as fungal infections and damage caused by pests. The microcontroller activates the hyperspectral sensor which consists of a light source, a diffraction grating and an array of detectors. The light from the environment is passed through the grating, which disperses the light into its component wavelengths. The detectors capture the reflected or transmitted light across multiple narrow bands, allowing the sensor to detect specific materials based on their unique spectral signatures. These signatures help identify characteristics such as fungal infections or pest damage on cotton balls by analyzing the subtle differences in the reflected wavelengths.

[0033] Simultaneously, the microcontroller activates the thermal camera 109 that detects infrared radiation emitted by objects, translating heat patterns into visual data. It is made up of an infrared sensor, a lens and a detector array. The infrared sensor captures the emitted thermal radiation from cotton balls and surrounding objects. The lens focuses the infrared radiation onto the detector array, which converts the radiation into temperature readings. The temperature variations detected by the thermal camera 109 indicate abnormalities such as fungal growth or pest damage, as these conditions often result in heat patterns that differ from healthy cotton balls.

[0034] The data from both the hyperspectral sensor and the thermal camera 109 are synchronized by the microcontroller. The microcontroller processes the spectral data from the hyperspectral sensor and the thermal data from the camera 109, combining both sources of information to detect cotton balls exhibiting defects, such as fungal infections and damage caused by pests.

[0035] Based on this synchronized data, the microcontroller activates the robotic arm 108 to carefully transfer the cotton balls exhibiting signs of disease or damage into the designated partition of the chamber 106 specifically reserved for defective cotton balls. Meanwhile, the healthy and matured cotton balls are placed in a separate partition within the chamber 106 for proper storage. This process ensures that damaged or infected cotton balls are isolated from the healthy ones, preventing cross-contamination and preserving the quality of the cotton.

[0036] An articulated L-shaped telescopic bar 110 configured with a nozzle is connected to a pesticide tank 111 installed within the housing 101 that is actuated by the microcontroller to spray disinfectant into the section of the chamber 106 containing infected cotton balls helping to protect the cotton from further damage. The telescopic bar 110 is linked to a pneumatic unit, including an air compressor, air cylinders, air valves and piston which works in collaboration to aid in extension and retraction of the bar 110 to position the nozzle in proximity to the cotton balls.

[0037] The nozzle used herein is preferably an electronic nozzle that operates through precise control facilitated by a solenoid valve actuated by the microcontroller. When the microcontroller sends an electrical signal to the solenoid coil, it generates a magnetic field that moves the valve's armature, allowing to spray disinfectant into the section of the chamber 106 containing infected cotton balls, thus helping to protect the cotton from further damage.

[0038] The user accesses a touch enabled display unit 112 mounted on the housing 101 to provide touch input regarding dispensing specific quantity of cotton balls. The display unit 112 consists of multiple layers, including a transparent conductive layer such as indium tin oxide (ITO) coated glass, which forms the surface that users directly touch. Beneath the layer lies a grid of electrodes, typically made of a conductive material like copper or silver, arranged in rows and columns. When the user touches the display unit 112, it creates a measurable change in capacitance at the point of contact, altering the electrical field between the electrodes. This change is detected by the controller circuitry embedded within the display unit 112, which interprets the position and intensity of the touch. The controller then converts this data into digital signals representing user inputs, which are further processed by the microcontroller.

[0039] Upon processing the user’s input, the microcontroller actuates a sorter conveyor 113 disposed in the housing 101 to dispensed cotton balls from the chamber 106 into a box 114 provided within the housing 101. The sorter conveyor 113 works by using motorized pulleys that loop over a long stretch of thick belt made upon of high durable material. When motors in the pulleys operate at the same speed and spin in the same direction, the belt moves between the pulleys. Thus, the conveyor 113 works and translate the cotton balls into a box 114 provided within the housing 101.

[0040] A robotic link 115 is located in the housing 101 that is activated by the microcontroller to remove foreign material from the cotton balls before dispensing. The robotic link 115 is able to perform the designated task with high efficiency and accuracy, wherein the microcontroller actuates the robotic link 115 to extend towards the conveyor 113 to remove foreign material from the cotton balls before dispensing.

[0041] After the removal of foreign material from the cotton balls, the microcontroller actuates a sliding unit 116 installed within the housing 101 and mounted with the box 114 to enable translation of the box 114 from an end of the conveyor 113 towards an outwards region of the housing 101. The sliding unit 116 include sliding rack and rail, such that the box 114 is mounted over the racks that are electronically operated by the microcontroller for moving over the rails.

[0042] The sliding unit 116 is powered by a DC (direct current) motor that is actuated by the microcontroller by providing required electric current to the motor. The motor comprises of a coil that converts the received electric current into mechanical force by generating magnetic field, thus the mechanical force provides the required power to the rack to provide sliding movement to the box 114 towards the outward region of the housing 101 for convenient access and further processing of the cotton balls.

[0043] Each section of the chamber 106 is equipped with a hinged lid that is easily opened to allow the cotton balls to be moved from the chamber 106 to the conveyor 113. The hinge lid is configured with a motorized hinge joint comprises of a pair of leaf that is screwed with the surfaces of the lid. The leaf is connected with each other by means of a cylindrical member integrated with a shaft coupled with a DC (Direct Current) motor to provide required movement to the hinge joint. The rotation of the shaft in clockwise and anti-clockwise aids in opening and closing of the hinge joint respectively. Hence the microcontroller actuates the hinge joint that in turn provides movement to the lid for efficient transfer of cotton balls to the conveyor 113.

[0044] Plurality of iris holes are provided underneath the chamber 106 for draining of disinfectant after soaking of the infected cotton balls in the disinfectants. The iris holes consist of a flexible, circular element with a series of overlapping segments that expand or contract to adjust the diameter of the opening. When the cotton balls are soaked in disinfectant, the diaphragm contracts, reducing the size of the hole and preventing excess liquid from escaping. Conversely, when the cotton balls need to be drained, the diaphragm expands, allowing disinfectant to flow out through the iris hole. This mechanism ensures controlled drainage, preventing overflow and ensuring that only the necessary amount of disinfectant is drained from the chamber 106, while the remaining liquid stays contained.

[0045] The microcontroller also activates a Peltier unit 117 integrated within each section of the chamber 106 to heat the soaked cotton balls in order to dry the cotton balls. The The Peltier unit 117 operates based on the Peltier effect, a thermoelectric phenomenon where heat is transferred between two different types of semiconductor materials. The Peltier unit 117 consists of alternating n-type and p-type semiconductor elements, which are arranged in a series. When an electric current is applied to these elements, heat is absorbed from one side of the unit and transferred to the other, resulting in a cooling effect on one side and a heating effect on the opposite side. This heating side is used to dry the soaked cotton balls by raising their temperature and removing excess moisture.

[0046] Further, the LIDAR sensor 103 in synchronization with the imaging unit 107, categorizes the cotton balls based on parameters such as fiber length, strength and micronaire reading. This data is used to grade the cotton balls and are stored in separate sections of the chamber 106 according to their quality. The microcontroller processes the grading information and assigns a price to the dispensed cotton balls based on their grade. A QR (Quick Response) code corresponding to the price is generated and displayed on the touch-enabled display unit 112 for allowing the user to scan the code for payment, facilitating seamless transactions for the dispensed cotton balls.

[0047] The device is associated with a battery for providing the required power to the electronically and electrically operated components including the microcontroller, electrically powered sensors, motorized components and alike of the device. The battery within the device is preferably a lithium-ion-battery which is a rechargeable battery and recharges by deriving the required power from an external power source. The derived power is further stored in form of chemical energy within the battery, which when required by the components of the device derive the required energy in the form of electric current for ensuring smooth and proper functioning of the device.

[0048] The present invention works best in the following manner, where the cuboidal housing 101 as disclosed in the invention is developed to be positioned on the ground in proximity to cotton plants. Upon activation, the microcontroller triggers the LIDAR sensor 103 which detects the terrain's surface contours and available pathways while avoiding obstacles to actuate motorized omnidirectional wheels and telescopic rods 102 to allow the housing 101 to move through the cotton field. Simultaneously, the imaging unit 107 is synchronized with the proximity sensor that captures images of nearby cotton plants to identify those suitable for harvesting. Once the cotton plant is detected, the microcontroller actuates articulated L-shaped telescopic grippers 105 to grasp the plant while the telescopic link 104 with the motorized blade cuts the cotton balls from the plants. These cotton balls are stored in the partitioned chamber 106 within the housing 101. The hyperspectral sensor and thermal camera 109 are integrated into the device to detect any defects in the cotton balls, such as fungal infections or pest damage. The microcontroller directs the robotic arm 108 to separate the damaged cotton balls and store them in the dedicated section. The pesticide spraying mechanism using the nozzle connected to the tank 111 further ensures that the infected cotton balls are treated to prevent further deterioration. After harvesting, the cotton balls are processed and sorted based on their quality, with the LIDAR and imaging unit 107 working together to categorize the cotton according to fiber length, strength, and micronaire reading. The price is then determined based on the cotton's grade and the QR code is displayed for user payment. The entire system is automated, from navigation to harvesting, sorting and dispensing, providing an efficient, seamless solution for cotton farming.
