[0002] Agricultural machinery is an important part of modern agricultural production, and its application scope covers multiple links such as planting, fertilizing, irrigation, and harvesting. With the progress of technology, agricultural machinery is gradually developing towards intelligence and automation.

The material distribution box is connected to the bottom of the storage box. A controller is installed on the outer wall of the storage box, and grips are fixed on both sides of the controller on the outer wall of the storage box. The seeding mechanism is composed of a feeding component, a depth adjustment component, and a material distribution component; The feeding component is movably arranged at the bottom inside the protective box. The material distribution component is installed inside the material distribution box for uniform distribution of seeds. The depth adjustment component is connected to the material distribution component, and the depth adjustment component is used to control the seeding depth of the feeding component and the distribution ratio of the material distribution component. The controller is electrically connected to the depth adjustment component.

[0007] Specifically, in this technical solution, the blanking component includes an insertion block. A blanking guide groove is formed inside the insertion block. A return plate is fixed to the top of the insertion block. The outer wall of the return plate fits against the inner wall of the protective box. Support springs are fixed to both sides of the lower surface of the return plate. A receiving hose is provided at the center of the top of the insertion block. The bottom end of the receiving hose is communicated with the top end of the blanking guide groove.

[0008] Specifically, in this technical solution, the bottom end of the insertion block penetrates through the bottom of the protective box. The bottom end of the blanking guide groove is located on the side wall of the bottom of the insertion block and is communicated with the outside. The outer walls of the return plates are all slidably connected to the inner wall of the protective box. The return plate is located below the fixing plate.

[0009] Specifically, in this technical solution, the depth adjustment component includes a bidirectional motor and a laser distance sensor. The bidirectional motor is fixed to one side of the lower surface of the mounting plate by screws. A threaded rod is flange-connected to one output end of the bidirectional motor. A square sleeve is sleeved on the threaded rod. The bottom outer wall of the square sleeve penetrates through the fixing plate and is slidably connected to the contact part. The bottom end of the square sleeve matches the upper surface of the return plate provided in the blanking component.

[0010] Specifically, in this technical solution, the other output end of the bidirectional motor penetrates through the mounting plate and is flange-connected to a rotating shaft. A driving bevel gear is fixedly installed on the rotating shaft. The laser distance sensor is embedded in the return plate provided in the blanking component. The laser distance sensor is connected to the controller through a transmission line. The bidirectional motor is connected to the controller through a wire.

[0011] Specifically, in this technical solution, a circular cavity is formed in the material distribution box. Feeding holes and discharging holes are respectively formed at the center of the top and bottom of the material distribution box. The feeding hole and the discharging hole are both communicated with the circular cavity. The bottom end of the storage tank is communicated with the feeding hole.

[0012] Specifically, in this technical solution, a feeding pipe penetrates through the center of the fixing plate. The top end of the feeding pipe is communicated with the discharging hole. The top end of the receiving hose provided in the blanking component is connected to the bottom end of the feeding pipe.

[0013] Specifically, in this technical solution, the material distribution component includes a rotating wheel. The rotating wheel is movably arranged in the circular cavity. Storage grooves are symmetrically formed on the outer edge of the rotating wheel. The feeding hole and the discharging hole both match the storage grooves.

[0014] Specifically, in this technical solution, the rotating wheel is rotationally connected to the inner wall of the circular cavity through a shaft rod. A transmission shaft is fixedly connected to one shaft rod of the rotating wheel. The transmission shaft penetrates through the material distribution box and is rotationally connected to the inner wall of the protective box.

[0015] According to the above technical solution, a method for using an agricultural machinery sowing device based on intelligent control will also be provided, including the following steps: Step 1, sowing preparation: The operator pours peanut seeds into the storage bin. Some seeds enter the distribution bin through the feeding hole and fall into the storage tank. Then, the operator holds the handle and makes the protective box perpendicular to the ground. Step 2, sowing depth adjustment: The operator starts the bidirectional motor through the controller. The bidirectional motor controls the rotation of the threaded rod and the rotating shaft. The threaded rod controls the downward movement of the square sleeve and pushes the spring plate downward. The spring plate pushes the insertion block downward, so that the bottom end of the insertion block inserts into the soil to a predetermined depth. The laser distance sensor monitors the distance from the fixed plate in real time and transmits the data to the controller to ensure that the insertion block is stably inserted to the predetermined depth. Step 3, sowing execution: The rotating shaft drives the driven bevel gear through the driving bevel gear, driving the rotating wheel to rotate, so that the storage tank containing peanut seeds rotates to the discharge hole. The seeds fall into the predetermined position in the soil under the action of gravity through the conveying pipe, the connecting hose and the feeding chute, completing the sowing. Step 4, reset and repetition: After sowing, the controller controls the bidirectional motor to reset the feeding assembly to the initial position, reconfirm the sowing depth and position to ensure consistency, and then continue the next round of sowing operations until the sowing task of the entire area is completed.

[0016] In summary, the present invention mainly has the following beneficial effects: By driving the threaded rod and the square sleeve with a bidirectional motor, the insertion depth of the insertion block is dynamically adjusted to ensure that the seeds are always implanted into the soil at a predetermined depth, and in cooperation with the laser distance sensor, the sowing depth can be monitored in real time and accurately controlled, solving the problem of inconsistent depth caused by differences in soil conditions in the prior art, and improving the germination rate and growth quality of seeds; At the same time, when adjusting the insertion depth of the insertion block, the rotating wheel is driven to move. The rotating wheel rotates driven by the transmission shaft, and the seeds are evenly distributed through the storage tank and accurately put into the soil through the conveying pipe and the connecting hose, ensuring that the seeds are put at the accurate depth, avoiding missed sowing or repeated sowing caused by asynchronous depth adjustment and material distribution, and ensuring the uniformity of seed distribution; The bidirectional motor forms a "pressure sensing - power compensation" mechanism through the threaded rod and the support spring, which can adapt to various soil conditions such as clay, sandy soil, and wet soil without manual intervention. The controller processes the laser ranging data in real time, automatically adjusts the motor speed and steering, realizes the dynamic self - adaptation of the sowing depth, significantly reduces the labor intensity of the operator, and improves the operation efficiency.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0020] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0021] In this embodiment, please refer to Figures 1-5As shown, an agricultural mechanical sowing device based on intelligent control includes a protective box 1, a material storage box 2 on the top, and a sowing mechanism 3 for controlling the sowing depth and uniform feeding inside, wherein a mounting plate 101 and a fixing plate 102 are fixed in sequence inside the protective box 1, a square through groove 1011 is opened on the mounting plate 101, a material distribution box 103 is fixed in the square through groove 1011, and the material distribution box 103 is connected to the bottom of the material storage box 2, a controller 201 is installed on the outer wall of the material storage box 2, and handles 202 are fixed on the outer wall of the material storage box 2 on both sides of the controller 201, and the sowing mechanism 3 is composed of a feeding component 4, a depth adjustment component 5 and a material distribution component 6; wherein rollers can also be installed on both sides of the bottom of the protective box 1 to facilitate movement and adjustment of position and improve operation flexibility.

[0022] The feeding component 4 is movably arranged at the bottom of the protective box 1, and the dividing component 6 is installed in the dividing box 103 for uniform distribution of seeds. The depth adjustment component 5 is connected to the dividing component 6, and the depth adjustment component 5 is used to control the sowing depth of the feeding component 4 and the distribution ratio of the dividing component 6, and the controller 201 is electrically connected to the depth adjustment component 5.

[0023] When sowing peanuts, the operator pours the peanut seeds into the storage box 2, and some of the seeds enter the distribution box 103 through the feed hole 1032 and fall into the storage tank 602 at the top. Then, the operator holds the handle 202 to push the device forward. After reaching the sowing area, it is perpendicular to the ground. The controller 201 starts the depth adjustment component 5, and the depth adjustment component 5 accurately adjusts the feeding component 4 and the distribution component 6 respectively, so that the actuator of the feeding component 4 (the insert block 401 in the text) can be inserted to the predetermined depth. At the same time, the actuator of the distribution component 6 (the rotating wheel 601 in the text) rotates at a uniform speed, so that the two storage tanks 602 are interchanged, the storage trough 602 containing the peanut seeds is rotated downward, and the peanut seeds enter the feeding assembly 4 through the discharge hole 1033 and the feeding pipe 7, and then fall into the soil, realizing precise sowing, so that the sowing depth can be monitored and accurately controlled in real time, solving the problem of inconsistent depth caused by differences in soil conditions in the prior art, improving the germination rate and growth quality of seeds, ensuring that seeds are placed at a precise depth, avoiding missed sowing or re-sowing due to asynchronous depth adjustment and material distribution, ensuring uniformity of seed distribution, and realizing dynamic adaptation of sowing depth, significantly reducing the labor intensity of operators and improving work efficiency.

[0024] See also Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown in the figure, the blanking component 4 includes an insertion block 401. A blanking guide groove 4011 is formed inside the insertion block 401. A return plate 403 is fixed to the top end of the insertion block 401. The outer wall of the return plate 403 is in contact with the inner wall of the protective box 1. Support springs 4031 are fixed on both sides of the lower surface of the return plate 403. A receiving hose 402 is provided at the center of the top end of the insertion block 401. The bottom end of the receiving hose 402 is communicated with the top end of the blanking guide groove 4011. The bottom end of the insertion block 401 passes through the bottom of the protective box 1. The bottom end of the blanking guide groove 4011 is located on the side wall of the bottom of the insertion block 401 and is communicated with the outside. The outer walls of the return plate 403 are slidably connected to the inner wall of the protective box 1. The return plate 403 is located below the fixing plate 102; The depth adjustment component 5 includes a bidirectional motor 501 and a laser distance sensor 505. The bidirectional motor 501 is fixed to one side of the lower surface of the mounting plate 101 by screws. A threaded rod 502 is flange-connected to an output end of the bidirectional motor 501. A square sleeve 503 is sleeved on the threaded rod 502. The outer wall of the bottom of the square sleeve 503 passes through the fixing plate 102 and is slidably connected to the contact part. The bottom end of the square sleeve 503 matches the upper surface of the return plate 403 provided in the blanking component 4. The other output end of the bidirectional motor 501 passes through the mounting plate 101 and is flange-connected to a rotating shaft 504. A driving bevel gear 5041 is fixedly installed on the rotating shaft 504. The laser distance sensor 505 is embedded in the return plate 403 provided in the blanking component 4. The laser distance sensor 505 is connected to the controller 201 through a transmission line. The bidirectional motor 501 is connected to the controller 201 through a wire.

[0025] When the controller 201 starts the bidirectional motor 501, the two output ends of the bidirectional motor 501 respectively control the rotation of the threaded rod 502 and the rotating shaft 504. At this time, the square sleeve 503 moves downward following the rotation of the threaded rod 502. The bottom end of the moving square sleeve 503 contacts the upper surface of the return plate 403 and pushes it downward. The return plate 403 drives the insertion block 401 to move downward and compresses the support spring 4031. When the insertion block 401 moves downward, its bottom end will be inserted into the soil, and the originally bent receiving hose 402 will be straightened. During the downward movement, the laser distance sensor 505 real-time monitors the distance between the return plate 403 and the fixing plate 102, and the detected data is sent to the controller 201, so that the operator can understand the depth change of the blanking component 4 in real time; When the support spring 4031 is compressed to the maximum, that is, when the return plate 403 reaches the predetermined position, the controller 201 sends a stop signal, the bidirectional motor 501 stops rotating, and the square sleeve 503 and the return plate 403 maintain their current positions to ensure that the insertion block 401 is stably inserted into the soil; When performing a reset, the controller 201 reversely starts the bidirectional motor 501, the threaded rod 502 and the rotating shaft 504 rotate reversely, the square sleeve 503 and the U-shaped plate 403 move upward accordingly, the support spring 4031 gradually returns to its original state, the insertion block 401 is pulled out of the soil, and the material receiving hose 402 returns to its bent state until the U-shaped plate 403 returns to its initial position. The controller 201 issues a stop signal again to complete the reset operation.

[0026] Please refer to Figures 5-7 As shown, a circular cavity 1031 is provided in the material distribution box 103. Feeding holes 1032 and discharging holes 1033 are respectively provided at the centers of the top and bottom ends of the material distribution box 103. The feeding holes 1032 and the discharging holes 1033 are both communicated with the circular cavity 1031. The bottom end of the storage box 2 is communicated with the feeding hole 1032. A material conveying pipe 7 is provided through the center of the fixing plate 102. The top end of the material conveying pipe 7 is communicated with the discharging hole 1033. The top end of the material receiving hose 402 provided in the material discharging assembly 4 is connected to the bottom end of the material conveying pipe 7; The material distribution assembly 6 includes a rotating wheel 601. The rotating wheel 601 is movably arranged in the circular cavity 1031. Storage grooves 602 are symmetrically provided on the outer edge of the rotating wheel 601. The feeding holes 1032 and the discharging holes 1033 are both matched with the storage grooves 602. The rotating wheel 601 is rotationally connected to the inner wall of the circular cavity 1031 through a shaft rod 604. A transmission shaft 603 is fixedly connected to one shaft rod 604 of the rotating wheel 601. The transmission shaft 603 passes through the material distribution box 103 and is rotationally connected to the inner wall of the protection box 1. A driven bevel gear 6031 is fixedly installed on the transmission shaft 603. The driven bevel gear 6031 is meshed with the driving bevel gear 5041 provided in the depth adjustment assembly 5.

[0027] When the bidirectional motor 501 is working, its rotating shaft 504 drives the driving bevel gear 5041 to rotate. The rotating driving bevel gear 5041 drives the meshed driven bevel gear 6031 to rotate. The driven bevel gear 6031 drives the transmission shaft 603 and the rotating wheel 601 to rotate synchronously, so that the two storage grooves 602 are alternately aligned with the feeding hole 1032 and the discharging hole 1033, realizing continuous conveying and distribution of materials, ensuring the uniformity and efficiency of sowing. With the precise rotation of the rotating wheel 601, the peanut seeds smoothly enter the material receiving hose 402 through the material conveying pipe 7 and finally accurately fall into the soil through the material discharging guide groove 4011.

[0028] Please refer to Figures 1-9 As shown, according to the above embodiments, a method used for an agricultural machinery sowing device based on intelligent control will also be provided, including the following steps: Step 1. Sowing preparation: The operator pours peanut seeds into the storage bin 2. Some seeds enter the distribution bin 103 through the feeding hole 1032 and fall into the storage groove 602. Then, the operator holds the handle 202 and makes the protective box 1 perpendicular to the ground. Step 2. Sowing depth adjustment: The operator starts the bidirectional motor 501 through the controller 201. The bidirectional motor 501 controls the rotation of the threaded rod 502 and the rotating shaft 504. The threaded rod 502 controls the downward movement of the square sleeve 503 and pushes the clip-shaped plate 403 downward. The clip-shaped plate 403 pushes the insertion block 401 downward, so that the bottom end of the insertion block 401 is inserted into the soil to a predetermined depth. The laser distance sensor 505 monitors the distance from the fixed plate 102 in real time and transmits the data to the controller 201 to ensure that the insertion block 401 is stably inserted to the predetermined depth. Step 3. Sowing execution: The rotating shaft 504 drives the driven bevel gear 6031 through the driving bevel gear 5041, driving the rotating wheel 601 to rotate, so that the storage groove 602 containing peanut seeds rotates to the discharge hole 1033. The seeds fall into the predetermined position in the soil under the action of gravity through the feed pipe 7, the connecting hose 402 and the feeding chute 4011, completing the sowing. Step 4. Reset and repeat: After sowing is completed, the controller 201 controls the bidirectional motor 501 to reset the feeding component 4 to the initial position, and reconfirms the sowing depth and position to ensure consistency. Then, continue the next round of sowing operations until the sowing task for the entire area is completed.

[0029] The working principle of the present invention is as follows: When carrying out the sowing operation of peanuts, the operator pours peanut seeds into the storage bin 2. Some seeds enter the distribution bin 103 through the feeding hole 1032 and fall into the storage groove 602 at the top. Then, the operator holds the handle 202 and pushes the device forward. After reaching the sowing area, it is perpendicular to the ground. The controller 201 starts the bidirectional motor 501. The two output ends of the bidirectional motor 501 respectively control the rotation of the threaded rod 502 and the rotating shaft 504. At this time, the square sleeve 503 moves downward following the rotation of the threaded rod 502. The bottom end of the moving square sleeve 503 contacts the upper surface of the clip-shaped plate 403 and pushes it downward. The clip-shaped plate 403 drives the insertion block 401 to move downward and squeezes the support spring 4031. The bottom end of the insertion block 401 moves downward and will be inserted into the soil, and will straighten the originally bent connecting hose 402. During the downward movement, the laser distance sensor 505 monitors the distance between the clip-shaped plate 403 and the fixed plate 102 in real time, and the detected data is sent to the controller 201, so that the operator can understand the depth change of the feeding component 4 in real time. When the compression of the support spring 4031 reaches the maximum, that is, when the return plate 403 reaches the predetermined position, the controller 201 issues a stop signal, the bidirectional motor 501 stops rotating, and the square sleeve 503 and the return plate 403 maintain their current positions to ensure that the insertion block 401 is stably inserted into the soil. Meanwhile, the rotating shaft 504 drives the rotation of the driving bevel gear 5041. The rotating driving bevel gear 5041 drives the engaged driven bevel gear 6031 to rotate. The driven bevel gear 6031 drives the transmission shaft 603 and the rotating wheel 601 to rotate synchronously, enabling the two storage bins 602 to alternately align with the feed hole 1032 and the discharge hole 1033, realizing the continuous conveying and distribution of materials, ensuring the uniformity and efficiency of sowing. With the precise rotation of the rotating wheel 601, the peanut seeds smoothly pass through the feed pipe 7 into the receiving hose 402 and finally accurately fall into the soil through the blanking chute 4011 to complete single-point sowing.

An agricultural machinery sowing method based on intelligent control, characterized in that, A method used for an agricultural machinery seeding device based on intelligent control according to any one of claims 1-9 includes the following steps: Step 1, seeding preparation. The operator pours peanut seeds into the storage box (2). Some seeds enter the material distribution box (103) through the feeding hole (1032) and fall into the storage groove (602). Then, the operator holds the handle (202) to make the protection box (1) perpendicular to the ground. Step 2, seeding depth adjustment. The operator starts the bidirectional motor (501) through the controller (201). The bidirectional motor (501) controls the rotation of the threaded rod (502) and the rotating shaft (504). The threaded rod (502) controls the downward movement of the square sleeve (503) and pushes the U-shaped plate (403) to move downward. The U-shaped plate (403) pushes the insertion block (401) to move downward, so that the bottom end of the insertion block (401) is inserted into the soil to a predetermined depth. The laser distance sensor (505) monitors the distance from the fixed plate (102) in real time and transmits the data to the controller (201) to ensure that the insertion block (401) is stably inserted to the predetermined depth. Step 3: Sowing execution. The rotating shaft (504) drives the driven bevel gear (6031) through the driving bevel gear (5041), driving the rotating wheel (601) to rotate, so that the storage tank (602) containing peanut seeds rotates to the discharge hole (1033). The seeds fall into the predetermined position in the soil under the action of gravity through the material conveying pipe (7), the receiving hose (402) and the blanking guide groove (4011), completing the sowing. Step 4: Reset and repeat. After sowing is completed, the controller (201) controls the bidirectional motor (501) to reset the blanking assembly (4) to the initial position, reconfirm the sowing depth and position to ensure consistency, and then continue the next round of sowing operations until the sowing task for the entire area is completed.
