[0001] The present invention mainly relates to the technical field of agricultural machinery, and specifically to an agricultural machinery sowing device and method based on intelligent control. Background Art

[0002] Agricultural machinery is an important part of modern agricultural production. Its application scope covers planting, fertilizing, irrigation, harvesting and other links. With the advancement of science and technology, agricultural machinery is gradually developing towards intelligence and automation. When sowing peanuts, agricultural machinery can achieve uniform sowing.

[0004] Although the above technology can evenly sow peanuts, achieving the effects of fast sowing speed, saving time and reducing manpower, it cannot dynamically adjust the sowing depth according to different soil conditions (such as hardness and humidity), resulting in inconsistent sowing depth, affecting the germination rate and growth quality of the seeds. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an agricultural machinery sowing device and method based on intelligent control to solve the technical problems raised in the above background technology.

A mounting plate and a fixing plate are fixed in sequence inside the protective box. A square through-slot is formed on the mounting plate. A material distribution box is fixed in the square through-slot. The material distribution box is connected to the bottom of the material storage box. A controller is installed on the outer wall of the material storage box. Handles are fixed to the outer wall of the material storage box on both sides of the controller. The sowing mechanism consists of a feeding assembly, a depth adjustment assembly, and a material distribution assembly.

[0008] The feeding assembly is movably arranged at the bottom of the protective box, the dividing assembly is installed in the dividing box for uniform distribution of seeds, the depth adjustment assembly is connected to the dividing assembly, and the depth adjustment assembly is used to control the sowing depth of the feeding assembly and the distribution ratio of the dividing assembly, and the controller is electrically connected to the depth adjustment assembly.

[0009] Specifically, the present technical solution comprises a plug block, a material discharge guide groove is provided inside the plug block, a circular plate is fixed to the top end of the plug block, the outer wall of the circular plate is in contact with the inner wall of the protective box, support springs are fixed on both sides of the lower surface of the circular plate, a material connection hose is provided at the center of the top end of the plug block, and the bottom end of the material connection hose is connected to the top end of the material discharge guide groove.

[0010] Specifically, the bottom end of the insert block passes through the bottom of the protective box, the bottom end of the discharge guide groove is located on the bottom side wall of the insert block and is connected to the outside, the outer walls of the circular plate are slidably connected to the inner wall of the protective box, and the circular plate is located below the fixed plate.

[0011] Specifically, the depth adjustment component includes a bidirectional motor and a laser ranging sensor. The bidirectional motor is fixed to one side of the lower surface of the mounting plate by screws. One output end flange of the bidirectional motor is connected to a threaded rod. A square sleeve is sleeved on the threaded rod. The bottom outer wall of the square sleeve passes through the fixed plate and is slidably connected to the contact part. The bottom end of the square sleeve matches the upper surface of the circular plate set in the blanking component.

[0012] Specifically, the other output end of the bidirectional motor passes through the mounting plate and is flange-connected to the rotating shaft. An active bevel gear is fixedly mounted on the rotating shaft. The laser ranging sensor is embedded in the circular plate provided in the blanking assembly. The laser ranging sensor is connected to the controller through a transmission line, and the bidirectional motor is connected to the controller through a wire.

[0013] Specifically, a circular cavity is provided in the distribution box, and a feed hole and a discharge hole are respectively provided at the center of the top and bottom ends of the distribution box. The feed hole and the discharge hole are both connected to the circular cavity, and the bottom end of the storage box is connected to the feed hole.

[0014] Specifically, the center of the fixed plate is provided with a feed pipe, the top end of the feed pipe is connected to the discharge hole, and the top end of the material receiving hose provided in the discharge assembly is connected to the bottom end of the feed pipe.

[0015] Specifically, the material dividing assembly includes a rotating wheel, which is movably arranged in a circular cavity. The outer edge of the rotating wheel is symmetrically provided with a material storage trough, and the material inlet and outlet holes are matched with the material storage trough.

[0016] Specifically, the rotating wheel is rotatably connected to the inner wall of the circular cavity through a shaft, and one shaft of the rotating wheel is fixedly connected to a transmission shaft. The transmission shaft passes through the distribution box and is rotatably connected to the inner wall of the protective box. A driven bevel gear is fixedly installed on the transmission shaft, and the driven bevel gear is meshed with the active bevel gear provided in the depth adjustment assembly.

[0017] According to the above technical solution, a method used by an agricultural machinery sowing device based on intelligent control is also provided, comprising the following steps:

[0018] Step 1: Preparation for sowing: The operator pours peanut seeds into the storage box. Some seeds enter the distribution box through the feeding hole and fall into the storage trough. Then, the operator holds the handle and places the protective box vertically on the ground.

[0019] Step 2: Adjust the sowing depth. 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 square sleeve to move downward and pushes the circular plate downward. The circular plate pushes the insert downward so that the bottom end of the insert is inserted into the soil to the predetermined depth. The laser ranging sensor monitors the distance to the fixed plate in real time and transmits the data to the controller to ensure that the insert is stably inserted into the predetermined depth.

[0020] Step 3: Sowing is executed. The rotating shaft drives the driven bevel gear through the active bevel gear, which drives the rotating wheel to rotate, so that the storage trough containing peanut seeds moves to the discharge hole. Under the action of gravity, the seeds fall into the predetermined position of the soil through the feeding pipe, the receiving hose and the discharge guide trough, completing the sowing.

[0021] Step 4: Reset and repeat. After sowing is completed, the controller controls the bidirectional motor to reset the blanking assembly to the initial position, reconfirm the sowing depth and position to ensure consistency, and then continue the next round of sowing operation until the sowing task of the entire area is completed.

[0022] In summary, the present invention has the following major beneficial effects: a bidirectional motor drives the threaded rod and square sleeve to dynamically adjust the insertion depth of the insert, ensuring that the seeds are always implanted in the soil at a predetermined depth. Combined with a laser ranging sensor, the sowing depth can be monitored and precisely controlled in real time, solving the problem of inconsistent sowing depth caused by differences in soil conditions in the prior art and improving the germination rate and growth quality of seeds.

[0023] At the same time, when adjusting the insertion depth of the plug, the rotating wheel is driven to move. The rotating wheel rotates under the drive shaft, evenly distributes the seeds through the storage trough, and accurately drops them into the soil through the feeding pipe and the receiving hose, ensuring that the seeds are dropped at a precise depth, avoiding missed or repeated sowing caused by the lack of synchronization between depth adjustment and material distribution, and ensuring uniform seed distribution;

[0024] The bidirectional motor forms a "pressure sensing-dynamic compensation" mechanism through threaded rods and support springs, which can adapt to various soil conditions such as clay, sand, and wet soil without human intervention. The controller processes laser ranging data in real time, automatically adjusts the motor speed and direction, and achieves dynamic adaptation of the sowing depth, significantly reducing the labor intensity of the operator and improving work efficiency.

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] In this embodiment, please refer to Figure 1-Figure 5 As shown, an agricultural mechanical sowing device based on intelligent control includes a protective box 1, a storage box 2 above, and a sowing mechanism 3 for controlling the sowing depth and uniform feeding inside. The interior of the protective box 1 is fixed with a mounting plate 101 and a fixing plate 102 in sequence, and a square through groove 1011 is provided on the mounting plate 101. A distribution box 103 is fixed in the square through groove 1011, and the distribution box 103 is connected to the bottom of the storage box 2. A controller 201 is installed on the outer wall of the storage box 2, and handles 202 are fixed on the outer wall of the storage box 2 on both sides of the controller 201. The sowing mechanism 3 consists of a feeding component 4, a depth adjustment component 5 and a distribution component 6; rollers can also be installed on both sides of the bottom of the protective box 1 to facilitate movement and adjustment of position, thereby improving operation flexibility.

[0038] 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. The controller 201 is electrically connected to the depth adjustment component 5.

[0039] When sowing peanuts, the operator pours peanut seeds into the storage box 2, and some seeds enter the distribution box 103 through the feeding hole 1032 and fall into the storage trough 602 at the top. Then, the operator pushes the device forward by holding the handle 202. 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 constant speed, so that the two storage troughs are 602 are interchanged, and the storage trough 602 containing peanut seeds is rotated downward, and the peanut seeds enter the discharge assembly 4 through the discharge hole 1033 and the feed pipe 7, and then fall into the soil, realizing precise sowing, thereby being able to monitor and accurately control the sowing depth 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 uniform seed distribution, and realizing dynamic adaptation of sowing depth, significantly reducing the labor intensity of operators and improving work efficiency.

[0041] The depth adjustment component 5 includes a bidirectional motor 501 and a laser ranging sensor 505. The bidirectional motor 501 is fixed to one side of the lower surface of the mounting plate 101 by screws. One output end of the bidirectional motor 501 is flange-connected to a threaded rod 502. A square sleeve 503 is sleeved on the threaded rod 502. The bottom outer wall of the square sleeve 503 passes through the fixed plate 102 and is slidably connected to the contact part. The bottom end of the square sleeve 503 matches the upper surface of the circular 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 the rotating shaft 504. An active bevel gear 5041 is fixedly installed on the rotating shaft 504. The laser ranging sensor 505 is embedded in the circular plate 403 provided in the blanking component 4. The laser ranging sensor 505 is connected to the controller 201 through a transmission line, and the bidirectional motor 501 is connected to the controller 201 through a wire.

[0042] The controller 201 starts the bidirectional motor 501. The two output ends of the bidirectional motor 501 control the rotation of the threaded rod 502 and the rotating shaft 504 respectively. 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 circular plate 403 and pushes it to move downward. The circular plate 403 drives the plug block 401 to move downward and squeezes the support spring 4031. The plug block 401 moves downward and its bottom end is inserted into the soil, and the originally bent material connection hose 402 is straightened.

[0043] When the support spring 4031 is compressed to the maximum, that is, the circular 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 circular plate 403 maintain their current positions, ensuring that the insert 401 is stably inserted into the soil;

[0044] When resetting, the controller 201 starts the bidirectional motor 501 in reverse, the threaded rod 502 and the rotating shaft 504 rotate in the opposite direction, the square sleeve 503 and the circular plate 403 move up accordingly, the support spring 4031 gradually returns to its original state, the plug block 401 is pulled out of the soil, and the material connecting hose 402 returns to its bent state until the circular plate 403 returns to its initial position. The controller 201 sends a stop signal again to complete the resetting operation.

[0045] See also Figure 5-Figure 7 As shown, a circular cavity 1031 is provided in the distribution box 103, and a feed hole 1032 and a discharge hole 1033 are respectively provided at the center of the top and bottom ends of the distribution box 103, and the feed hole 1032 and the discharge hole 1033 are both connected to the circular cavity 1031, and the bottom end of the storage box 2 is connected to the feed hole 1032, and a feeding pipe 7 is passed through the center of the fixed plate 102, and the top end of the feeding pipe 7 is connected to the discharge hole 1033, and the top end of the material receiving hose 402 provided in the discharge assembly 4 is connected to the bottom end of the feeding pipe 7;

[0046] The material distribution component 6 includes a rotating wheel 601, which is movably arranged in the circular cavity 1031. The outer edge of the rotating wheel 601 is symmetrically provided with a material storage trough 602, and the material inlet hole 1032 and the material outlet hole 1033 are both matched with the material storage trough 602. The rotating wheel 601 is rotatably connected to the inner wall of the circular cavity 1031 through an axis rod 604. One axis rod 604 of the rotating wheel 601 is fixedly connected to a transmission shaft 603, and the transmission shaft 603 passes through the material distribution box 103 and is rotatably connected to the inner wall of the protective box 1. A driven bevel gear 6031 is fixedly installed on the transmission shaft 603, and the driven bevel gear 6031 is meshed with the active bevel gear 5041 provided in the depth adjustment component 5.

[0047] When the bidirectional motor 501 is working, its rotating shaft 504 will drive the active bevel gear 5041 to rotate, and the rotating active bevel gear 5041 will drive the meshing driven bevel gear 6031 to rotate, and the driven bevel gear 6031 will drive the transmission shaft 603 and the rotating wheel 601 to rotate synchronously, so that the two storage troughs 602 are alternately aligned with the feed hole 1032 and the discharge hole 1033, realizing continuous transportation and distribution of materials, ensuring the uniformity and efficiency of sowing, and 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 fall accurately into the soil through the discharge guide groove 4011.

[0048] See also Figures 1-9 As shown, according to the above embodiment, a method used by an agricultural machinery sowing device based on intelligent control is also provided, comprising the following steps:

[0049] Step 1: Preparation for sowing: The operator pours peanut seeds into the storage box 2. Some seeds enter the distribution box 103 through the feeding hole 1032 and fall into the storage trough 602. Then, the operator holds the handle 202 and holds the protective box 1 vertically to the ground.

[0050] Step 2: Adjusting the sowing depth. The operator activates the bidirectional motor 501 through the controller 201. The bidirectional motor 501 controls the threaded rod 502 and the rotating shaft 504 to rotate. The threaded rod 502 controls the square sleeve 503 to move downward and pushes the circular plate 403 downward. The circular plate 403 pushes the insert 401 downward so that the bottom end of the insert 401 is inserted into the soil to a predetermined depth. The laser ranging sensor 505 monitors the distance to the fixed plate 102 in real time and transmits the data to the controller 201 to ensure that the insert 401 is stably inserted into the predetermined depth.

[0051] Step 3: Sowing is executed. The rotating shaft 504 drives the driven bevel gear 6031 through the active bevel gear 5041, driving the rotating wheel 601 to rotate, so that the storage trough 602 containing the peanut seeds moves to the discharge hole 1033. Under the action of gravity, the seeds fall into the soil at a predetermined position through the feeding pipe 7, the receiving hose 402 and the discharge guide trough 4011, completing the sowing.

[0052] Step 4: Reset and repeat. After sowing is completed, the controller 201 controls the bidirectional motor 501 to reset the blanking component 4 to the initial position, reconfirm the sowing depth and position to ensure consistency, and then continue the next round of sowing operation until the sowing task of the entire area is completed.

[0053] The working principle of the present invention is:

[0054] When sowing peanuts, the operator pours peanut seeds into the storage box 2. Some seeds enter the distribution box 103 through the feeding hole 1032 and fall into the storage trough 602 at the top. Then, the operator pushes the device forward by holding the handle 202. After reaching the sowing area, the device 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 square sleeve 503 contacts the upper surface of the circular plate 403 and pushes it downward. The circular plate 403 drives the plug 401 to move downward and squeezes the support spring 4031. The plug 401 moves downward and its bottom end is inserted into the soil, and the originally bent material hose 402 is straightened. During the downward movement, the laser ranging sensor 505 monitors the distance between the circular plate 403 and the fixed plate 102 in real time, and sends the detected data to the controller 201, so that the operator can understand the depth change of the blanking component 4 in real time.

[0055] When the support spring 4031 is compressed to the maximum, that is, the circular 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 circular plate 403 maintain their current positions, ensuring that the insert 401 is stably inserted into the soil;

[0056] At the same time, the rotating shaft 504 will drive the active bevel gear 5041 to rotate, and the rotating active bevel gear 5041 will drive the meshed driven bevel gear 6031 to rotate, and the driven bevel gear 6031 will drive the transmission shaft 603 and the rotating wheel 601 to rotate synchronously, so that the two storage troughs 602 are alternately aligned with the feed hole 1032 and the discharge hole 1033, realizing continuous transportation and distribution of materials, ensuring the uniformity and efficiency of sowing, and 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 fall accurately into the soil through the discharge guide groove 4011, completing single-point sowing.

A method for an agricultural machinery seeding device based on intelligent control according to any one of claims 1 to 6, characterized in that: The following steps are involved: Step 1: Preparation for sowing: The operator pours peanut seeds into the storage box (2); some seeds enter the distribution box (103) through the feeding hole (1032) and fall into the storage trough (602); then the operator holds the handle (202) and places the protective box (1) vertically on the ground; Step 2: Adjusting the sowing depth. The operator starts the bidirectional motor (501) through the controller (201). The bidirectional motor (501) controls the threaded rod (502) and the rotating shaft (504) to rotate. The threaded rod (502) controls the square sleeve (503) to move downward and pushes the circular plate (403) to move downward. The circular plate (403) pushes the plug (401) downward so that the bottom end of the plug (401) is inserted into the soil to a predetermined depth. The laser ranging sensor (505) monitors the distance to the fixed plate (102) in real time and transmits the data to the controller (201) to ensure that the plug (401) is stably inserted into the predetermined depth. Step 3: Sowing is performed. The rotating shaft (504) drives the driven bevel gear (6031) through the active bevel gear (5041), driving the rotating wheel (601) to rotate, so that the storage tank (602) containing peanut seeds is rotated to the discharge hole (1033). Under the action of gravity, the seeds fall into the predetermined position of the soil through the feeding pipe (7), the receiving hose (402) and the discharge guide groove (4011), completing the sowing. Step 4: Reset and repeat. After the sowing is completed, the controller (201) controls the bidirectional motor (501) to reset the feeding assembly (4) to the initial position, confirm the sowing depth and position again to ensure consistency, and then continue the next round of sowing operation until the sowing task of the entire area is completed.
