Description:FIELD OF THE INVENTION

[0001] The present invention relates to a mulching sheet laying device that is capable of laying the mulching sheet by using the bamboo sticks for improving the crop yield and determining the type of sheet to be laid based on the forecast of the surrounding and the soil type thereby enhancing the agricultural efficiency.

BACKGROUND OF THE INVENTION

[0002] Laying a mulching sheet is essential in agriculture. The laying of the mulching sheet plays a crucial role in improving soil health, conserving moisture, and enhancing crop yield. By covering the soil, the mulching sheet reduces water evaporation, ensuring that plants receive adequate moisture for longer periods, which is especially beneficial in dry and arid regions. The sheet laying also suppresses weed growth by blocking sunlight, minimizing competition for nutrients and reducing the need for chemical herbicides. Additionally, the sheet helps regulate soil temperature, protecting crops from extreme heat or cold, thereby promoting healthier plant growth. Furthermore, mulching sheets reduce direct contact between fruits or vegetables and the soil, preventing rot and improving crop quality. Overall, using a mulching sheet enhances productivity, reduces labor costs, and promotes sustainable farming practices.

[0003] The traditional method of laying a mulching sheet involves manual labor, where farmers spread the sheet over the soil and secure using soil, stones, or wooden pegs. Additionally, adjustments for wind resistance and moisture control are done manually, making the method less efficient and labor-intensive. The traditional method of laying a mulching sheet is labor-intensive, time-consuming, and prone to errors such as uneven coverage and poor tensioning. Manual placement often results in improper soil contact, reducing effectiveness in weed control and moisture retention. Additionally, securing the sheet with soil or stones is inconsistent, making the sheet vulnerable to wind displacement. Frequent adjustments increase workload, reducing overall farming efficiency.

[0004] JP2009291125A discloses an operating machine for laying a mulching sheet working as follows: laying an upper sheet on top of a lower sheet to be laid in contact with the surface of a farm field; and putting soil on both sides of the sheets in a laying direction to be fixed to the surface of the farm field so as to facilitate heat retention of the surface of the farm field and prevention of evaporation of a disinfectant, and enable the upper sheet to be easily peeled. The operating machine for laying a mulching sheet includes a mulching part 10 comprising: a mulching extending part 8 which unwinds the mulching sheet to the running machine to be laid; and a mulching fixation part 9 which is fixed by putting soil on both sides of the mulching sheet. The operating machine supports a lower roll sheet 3a of the lower sheet 3 laid on the side of the farm field and an upper roll sheet 4a of the upper sheet 4 superimposed on the lower sheet 3 to the mulching extending part 8, and is fixed to both sides of the lower sheet 3 laid over the surface of the farm field and the upper sheet 4 superimposed on the lower sheet 3 by putting the soil via the mulching sheet fixing part 9 to be fixed.

[0005] JP2013176314A discloses a mulching sheet material capable of preventing agricultural environmental contamination due to pesticides and a method of laying a mulching sheet material. Solution: A mulching sheet material MS is used to cover soil E in a paddy field and is composed chiefly of high-strength plastics. The mulching sheet material includes a pesticide adsorption material composed chiefly of activated charcoal or low-temperature fired fly ash or their mixture, and a light-blocking black paint. The mulching sheet material has circular through holes with microscale diameters.

[0006] Conventionally, many devices have been developed for laying of the mulching sheet but they lack in detecting the moisture level of soil in the field for determining the suitable height at which the sheet is to be laid. They also lack in determining the type of sheet to be laid based on the forecast of the surrounding and the soil type.

[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 laying a mulching sheet by using the bamboo sticks for improving the crop yield and reducing the manual labor. The device should also be capable of detecting the moisture level of soil in the field for determining the suitable height at which the sheet is to be laid and determining the type of sheet to be laid based on the forecast of the surrounding and the soil type.

[0021] The present invention relates to a mulching sheet laying device that is capable of laying a mulching sheet by using the bamboo sticks for improving the crop yield and reducing the manual labor. Moreover, the developed device is capable of determining the type of sheet to be laid based on the forecast of the surrounding and the soil type thereby enhancing the agricultural efficiency.

[0022] Referring to Figure 1, an isometric view of a mulching sheet laying device is illustrated, comprising a rectangular frame 101 installed with a plurality of motorized rollers 102 each via a set of telescopically operated links 103, a platform 104 attached with the frame 101 and mounted with a chamber 105, a primary telescopically operated gripper 106 arranged on the platform 104, an inverted V-shaped member 107 mounted on the platform 104, an artificial intelligence-based imaging unit 108 mounted on the platform 104, a primary robotic arm 109 assembled on the platform 104, a cutting unit 110 equipped with the primary arm 109, a heating unit 111 configured with the platform 104, a plurality of telescopically operated pushers 112 installed around the member 107.

[0023] Figure 1 further illustrates a pair of secondary robotic arms 113 assembled on the frame 101 via a pair of motorized sliders 114 and each equipped with a shovel 115, a pair of secondary telescopically operated grippers 116 arranged on the sliders 114, a pair of motorized clippers 117 installed on the frame 101 via a pair of motorized sliding units 118, a cylindrical body 119 installed with the frame 101 via an L-shaped telescopically operated bar 120, a tertiary robotic arm 121 is configured with the frame 101, a blade 122 equipped with the tertiary robotic arm 121, a pair of tertiary telescopically operated grippers 123 are configured with the frame 101, a container 124 attached on the frame 101, a vessel 125 is housed in the body 119, a motorized iris lid 126 configured with the body 119.

[0024] The device disclosed herein employs a rectangular frame 101 positioned on an agricultural field. This frame 101 is typically constructed from materials that include but not limited to high-strength materials such as reinforced steel or durable aluminum alloys, which provide a robust and resilient enclosure capable of withstanding physical impacts and environmental stressors.

[0025] For activating the device, the user needs to press a push button which is arranged on the frame 101 which in turn activates all the related components for performing the desired task. After pressing the button, a closed electrical circuit is formed and current starts to flow that powers an inbuilt microcontroller to allow all the linked components to perform their respective task upon actuation.

[0026] The frame 101 is installed with a plurality of motorized rollers 102. Each roller 102 is mounted via a set of telescopically operated links 103 and each of the rollers 102 are installed with mulching sheets of different colors. The motorized rollers 102 function through a combination of electric motors to ensure controlled movement and adaptability. When actuated, the electric motors drive the rollers 102, rotating them at controlled speed.

[0027] A user-interface inbuilt in a computing unit that is wirelessly linked with the mirocontroller for enabling a user to give input details regarding seed to be sown in the field. The user input commands through the keyboard or touch interactive display panel of the computing unit that is transmitted to the microcontroller through a communication module. 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.

[0028] The microcontroller processes the input details to determine one of the sheet to be laid over the field, along with one of the rollers 102 wrapped with the determined sheet. Accordingly, the microcontroller actuates one of the set of links 103 to retract for positioning the determined roller 102 in proximity to the frame 101. The telescopically operated links 103 operate using a telescopic arrangement that allows the change in length dynamically while maintaining structural integrity. The link 103 typically consists of interlocking segments that slide within each other. The link 103 utilizes a pneumatic unit for the extension and retraction. The pneumatic unit for extension and retraction operates using compressed air to drive a piston inside a cylinder. When air is supplied to one side of the piston, it creates pressure that pushes the piston rod outward, causing extension. To retract, air is supplied to the opposite side while the initial chamber is vented, pulling the piston rod back. Hence, the determined roller 102 is placed in proximity to the frame 101.

[0029] For detecting the moisture level of soil in the field, a plurality of moisture sensors is arranged with the frame 101. The moisture sensors integrated with the frame 101 operate by measuring the soil's electrical properties to determine the moisture content. Each sensor consists of two conductive probes inserted into the soil, which function as electrodes. When activated, the sensor applies a small voltage across these probes and measures the resulting electrical resistance. Since, the water enhances soil conductivity, lower resistance indicates higher moisture levels, while higher resistance suggests drier soil. The collected data is then transmitted to the microcontroller, which processes and analyzes the moisture readings from multiple sensors across the field. Based on the detected moisture, the microcontroller determines a suitable height at which the sheet is to be laid.

[0030] If the soil moisture is low (indicating a dry environment), the device installs the sheet elevated above the soil to prevent excessive evaporation and maintain moisture levels. If the soil moisture is high (indicating a wet environment), the device installs the sheet in direct contact with the soil to enhance water retention and prevent weed growth.

[0031] A platform 104 is attached with the frame 101 and mounted with a chamber 105 that is stored with multiple bamboo sticks. The platform 104 is preferably made up of but not limited to stainless steel or aluminum which provides stability and resistance to corrosion. The microcontroller actuates a primary telescopically operated gripper 106 arranged on the platform 104 for gripping and placing pre-set number of sticks from the chamber 105 and aligning the sticks underneath an inverted V-shaped member 107 mounted on the platform 104, in a successive manner.

[0032] The primary telescopically operated gripper 106 functions by using the telescopic assembly. The telescopically operated gripper 106 utilizes the pneumatic unit for the operation as explained above. When activated by the microcontroller, the pneumatic unit extends or retracts the telescopic arm, adjusting the gripper’s reach. The gripper 106 consists of a set of motorized jaws, which opens and closes upon receiving signals from the microcontroller. Once the gripper 106 extends and reaches the chamber 105, the gripper 106 securely grips a pre-set number of sticks. The gripper 106 then retracts and moves the sticks for positioning underneath the inverted V-shaped member 107 on the platform 104.

[0033] Upon positioning the sticks underneath the member 107, the length of the sticks is detected. For detecting the length of the sticks, an artificial intelligence-based imaging unit 108 that is paired with a processor is mounted on the platform 104 that works in sync with an ultrasonic sensor. The imaging unit 108 comprises of an image capturing arrangement including a set of lenses that captures multiple images in vicinity of the sticks, and the captured images are stored within a memory of the imaging unit 108 in form of an optical data. The imaging unit 108 also comprises of the 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. The microcontroller processes the received data and detects the presence of the stick.

[0034] The ultrasonic sensor operates by emitting high-frequency sound waves toward the stick and measuring the time taken for the echo to return. Upon receiving a trigger from the microcontroller, the sensor’s transmitter emits a pulse that travels through the air until it strikes the end of the stick, then reflects back to the receiver. By calculating the time delay between the pulse emission and the echo reception, and knowing the speed of sound in air, the sensor accurately determines the distance to the stick's tip. So, the length of the sticks is detected.

[0035] Based on the detected length of the sticks, the microcontroller directs a primary robotic arm 109 that is assembled on the platform 104 for cutting the sticks via a cutting unit 110 equipped with the primary arm 109, in required length for laying the sheet at the height. The robotic arm 109 consists of linked segments connected by joints, which are powered by motors to enable movement in all directions. The rotary joints of the arm 109 enable rotational motion around a fixed axis, while prismatic joints allow for linear, sliding movement. The arm 109 is activated by the microcontroller to move the cutting unit 110.

[0036] The cutting unit 110 for cutting the sticks operates by using an electric motor to drive a sharp rotating blade, enabling precise and efficient cutting. When powered, the motor converts electrical energy into mechanical motion, which moves the cutting element at high speed. The cutting unit 110 features adjustable speed settings, automated controls, or guided tracks for enhanced accuracy in cutting the stick.

[0037] The platform 104 is equipped with a heating unit 111 that is actuated by the microcontroller for heating the platform 104 which results in heating of the sticks. The heating unit 111 operates as an electrically controlled thermal arrangement managed by the microcontroller. Internally, the heating unit 111 consists of resistive heating elements, typically made from nichrome wire, embedded within the platform surface. When actuated by the microcontroller, electrical current is supplied to these elements, causing them to generate heat due to electrical resistance. Hence, the heat is provided to the platform 104 which is again transmitted to the sticks.

[0038] The microcontroller actuates a plurality of telescopically operated pushers 112 that is positioned around the member 107 in a semi-circular arrangement. These pushers 112 extend for applying a pressure over the sticks to bend the sticks in U-shape. The telescopically operated pushers 112 consist of nested cylindrical segments that slide within one another, enabling a telescopic extension and retraction motion. These segments are driven by the pneumatic unit which functions in the similar manner as explained above. When actuated by the microcontroller, a synchronized extension or retraction sequence is achieved. The pusher 112 applies pressure on the sticks to bend the sticks in U-shape.

[0039] A pair of secondary robotic arms 113 is assembled on the frame 101 via a pair of motorized sliders 114. Each of the secondary robotic arms 113 is equipped with a shovel 115. The microcontroller actuates the secondary arms 113 for digging holes in the soil by means of the shovel 115 in synchronization with actuation of the sliders 114 to translate the secondary arms 113 along entire length of the frame 101 to dig holes along entire length of the frame 101. The secondary robotic arms 113 work in the similar manner as the primary robotic arm 109 explained above. The sliders 114 installed in the frame 101 consist of a sliding rail and a motorized slidable member connected to the sliding rail. The motorized slidable member is attached to the frame 101 and sliding rail on both sides to make the secondary robotic arm 113 slide. The slidable member is attached to a motor which provides movement in a bi-directional manner.

[0040] The sliders 114 provide movement to the secondary robotic arm 113 for digging the hole in the soil by using the shovel 115. The holes are dug in the soil for the installation of the bent sticks via a pair of secondary telescopically operated grippers 116. These secondary telescopically operated grippers 116 are arranged on the sliders 114 for inserting the bent sticks in the holes in an equidistant manner. The secondary telescopically operated grippers 116 work in the similar manner as the primary telescopically operated gripper 106 for inserting the bent sticks in the holes made in the soil.

[0041] A pair of motorized clippers 117 is mounted on the frame 101 via a pair of motorized sliding units 118. The microcontroller actuates the clippers 117 for gripping the free-ends of the determined sheet followed by the actuation of the sliding units 118 to translate the clippers 117 for unwrapping the sheet and laying the sheet over the installed bent sticks. The motorized clippers 117, function as precision gripping and handling devices controlled by the microcontroller. Each clipper 117 consists of two opposing jaws driven by a small electric motor to facilitate controlled opening and closing. When actuated, the microcontroller sends electrical signals to the clipper motors, causing the jaws to close around the free ends of the determined sheet, ensuring a secure grip.

[0042] Once the sheet is secured, the microcontroller then actuates the motorized sliding units 118, which translate the clippers 117 along predefined paths. The sliding units 118 works in the similar manner as the sliders 114 for providing the translation. This movement allows the gradual unwrapping and stretching of the sheet over the installed bent sticks in a controlled manner.

[0043] Upon laying of the sheet over the bent sticks, the holes are cut through the sheet in an equidistant manner for sowing seeds. For cutting holes through the sheet, a cylindrical body 119 is installed with the frame 101 via an L-shaped telescopically operated bar 120. The body 119 is having sharp ends. The microcontroller actuates the bar 120 to retract for cutting holes through the sheet. The L-shaped telescopically operated bar 120 utilizes the pneumatic unit in the similar manner as explained above for the retraction, enabling the cutting of the holes through the sheet by using the cylindrical body 119.

[0044] The microcontroller actuates a tertiary robotic arm 121 that is configured with the frame 101 for cutting the unwrapped sheet via a blade 122 equipped with the tertiary robotic arm 121. The tertiary robotic arm 121 works in the similar manner as the primary robotic arm 109. The blade 122, integrated with the tertiary robotic arm 121, functions as a precision cutting assembly controlled by the microcontroller. Internally, the blade 122 is mounted on a high-speed rotary motor for providing the cutting action. When actuated, the microcontroller sends electrical signals to the motor, controlling the speed and torque to ensure an efficient and clean cut through the unwrapped sheet.

[0045] A pair of tertiary telescopically operated grippers 123 are configured with the frame 101 via the sliders 114. These grippers 123 are actuated by the microcontroller to work in collaboration for gripping metal wire pieces from a container 124 attached on the frame 101. The gripped metal wire pieces are tied with the sticks for securing the sheet with the sticks. The tertiary telescopically operated grippers 123 work in the similar manner as the primary telescopically operated gripper 106 as mentioned above.

[0046] For storing the seeds to be sown, a vessel 125 is housed in the body 119. Post cutting the holes through the sheet, the microcontroller actuates a motorized iris lid 126 configured with the body 119 to open for dispensing seeds for sowing. The iris lid 126 operates using a series of interlinked, overlapping blades that open and close in a circular motion. The motor in the iris lid 126 drives a mechanical linkage that synchronously moves the blades apart, creating an opening for the seeds to pass through for sowing.

[0047] The type of sheet used also depends on the weather forecast of surroundings, as determined by a weather module installed on the frame 101 and type of soil, as determined by the imaging unit 108. The weather module, functions as an environmental sensing arrangement that collects real-time weather data to assist in selecting the appropriate sheet type.

[0048] Internally, the weather module consists of multiple sensors, including a temperature sensor to measure ambient temperature, a humidity sensor to assess moisture levels, and a barometric pressure sensor to predict weather trends. The temperature sensor measures ambient temperature to assist in selecting the appropriate sheet type. The sensor typically functions based on resistive temperature detection (RTD). In an RTD, temperature changes cause a predictable variation in electrical resistance, which is measured by the sensor and converted into a corresponding temperature value.

[0049] The humidity sensor measures ambient humidity levels to assist in selecting the appropriate sheet type. The sensor typically operates based on capacitive sensing principles. In a capacitive humidity sensor, two conductive plates with a hygroscopic dielectric material between them detect changes in capacitance as the material absorbs or releases moisture from the air. This change is converted into an electrical signal proportional to the relative humidity. So, the moisture level is detected.

[0050] The barometric pressure sensor mentioned herein above helps predict weather trends, aiding in the selection of the appropriate sheet type. The sensor typically operates using microelectromechanical systems (MEMS). In a MEMS-based sensor, a tiny diaphragm flexes in response to changes in atmospheric pressure, causing variations in capacitance, which are then converted into an electrical signal. The sensor continuously transmits pressure readings to the microcontroller, which processes the data to identify weather patterns. Based on this analysis, the microcontroller determines the most suitable sheet type, ensuring optimal performance based on environmental conditions.

[0051] For crops such as beans or cucumbers, which thrive in warmer conditions, dark or black mulches will be installed to retain heat and promote growth. In colder climates, a thicker layer of mulch can help insulate the soil and protect plant roots from frost.

[0052] For supplying power to electrical and electronically operated components, a battery is associated with the device. The battery powers electrical and electronic components by converting stored chemical energy into electrical energy. The battery’s terminals provide a voltage difference, allowing current to flow through circuits that supplies consistent energy to actuate and operate components like motors, sensors and microcontrollers, ensuring seamless functionality.

[0053] The present invention works best in the following manner, where the rectangular frame 101 installed with the plurality of motorized rollers 102, each via the set of telescopically operated links 103 where each of the rollers 102 are installed with mulching sheets of different colors.
