Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and specifically discloses an intelligent agricultural sowing device and method. Background Technology

[0002] In agricultural sowing operations, wheeled sowing equipment is widely used. Among intelligent agricultural power machinery, rice seed sowing is a key step in mechanized rice seedling raising. Before sowing, rice seeds need to be soaked and germinated. When the seed buds break through the bud and the length is controlled to about 1 mm, they are then spread out to dry until they are "moist inside and dry outside, not sticky to the touch" before being loaded into the seed box for sowing. At present, mechanical seed metering wheel is generally used as the core sowing component. The seed metering wheel rotates in the seed box to pick up seeds, realizing quantitative distribution of seed buds. It is widely used in rice seedling tray sowing operations.

[0003] For wheel-type seeding equipment, single or quantitative seed feeding is usually achieved by rotating the wheel to scrape the seeds. During operation, most of the seedlings accumulate in the seed box, with the seedlings at the bottom bearing greater pressure. The continuous squeezing between the seeds leads to frequent breakage of the tender shoots or detachment of the embryo, directly affecting the uniformity of seedling emergence and the success rate of planting. Retrieving seeds from the accumulated seedlings results in damage to the seedlings before they enter the seed metering device. During the feeding stage, the seedlings are prone to arching and clogging at the seed box outlet, often requiring manual tapping or auger assistance for feeding, which further exacerbates the detachment of the embryo. During the seed retrieval stage, the seed-scooping wheel rotates to scoop the seedlings from the accumulated seedlings, and the seedlings squeeze each other and rub against the parts, causing the tender shoots to break or be damaged. During the feeding stage, the seedlings rely on gravity to fall freely, and the landing point is easily deviated due to airflow disturbance, affecting the uniformity of plant spacing.

[0006] The V-shaped plate is connected to a seeding mechanism on one side corresponding to multiple discharge ports. The seeding mechanism is used to transport the seeds discharged from the discharge ports to the soil.

[0007] The seeding mechanism includes a connecting cylinder, inside which a rotating cylinder is rotatably connected.

One end of each of the two movable plates extends through to one side of the corresponding housing and is connected to both ends of the baffle.

[0013] Preferably, one side of the connecting cylinder is connected to one side of the V-shaped plate via a connecting block. A guide frame is connected to one side of the connecting cylinder at multiple feeding ports. One end of each guide frame is connected to one side of the V-shaped plate. Seed-taking grooves are circumferentially connected to the outer wall of the rotating cylinder. One side of several seed-taking grooves corresponds to one end of each guide frame. A seed-dropping port is opened on one side of the connecting cylinder at one side of several seed-taking grooves. One end of each seed-dropping tube is located at one of the multiple seed-dropping ports on one side of the connecting cylinder.

[0014] Preferably, there are two sets of mounting plates and five sets of vent pipes. The five vent pipes are distributed circumferentially inside the rotating drum. Ventilation slots are provided on one side of the inner wall of the rotating drum corresponding to the multiple seed-taking slots. Mounting pipes are connected to one side of the multiple vent pipes corresponding to the multiple vent slots. One end of the multiple mounting pipes is inserted into the vent slot. The seed-taking slot and the vent slot are connected through a filter block, so that gas is introduced into the seed-taking slot through the vent slot.

[0015] Preferably, the ventilation mechanism includes connecting pipes, and the connecting pipes of the two ventilation mechanisms are respectively connected to one side of the two mounting plates. Each connecting pipe has an air supply pipe connected to its outer surface. There are five sets of air supply pipes, and the five air supply pipes of the two ventilation mechanisms are respectively connected to both ends of the five air supply pipes.

Filter screens are embedded on one side of the first and second mounting boxes to facilitate air intake and exhaust.

[0017] A smart agricultural sowing method includes the following steps:

[0018] S1: Load rice seedlings into the seed storage box, open the discharge valve, and the seedlings fall into the V-shaped plate and are evenly distributed. Two winding motors drive the winding rollers and the pulling cloth to keep the selection plate horizontal, and the seedlings fall into the selection holes. Each selection hole can hold two or three seedlings.

[0019] S2: The winding motor alternately winds up the pulled cloth on both sides, driving the selection plate to swing back and forth so that the buds enter the selection holes in an orderly single layer;

[0020] S3: When the selection plate swings to the preset tilt angle, the blocking mechanism opens the selection hole, allowing the seed to fall into the seed-taking groove of the seed-laying mechanism; by controlling the air path, negative pressure is provided to absorb the seed when the seed-taking groove receives the seed, and positive pressure is provided to blow it out when the seed is placed, thus completing the sowing.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention, by setting a V-shaped plate and a selection plate with selection holes, enables the seedlings to be distributed in a single layer in an orderly manner before entering the seed metering device. Each selection hole can only hold two or three seedlings, avoiding the bottom compression damage caused by the accumulation of seedlings in the seed box of traditional seeders. For rice seedlings, it effectively prevents the embryos from breaking and falling off due to prolonged pressure. At the same time, the selection plate is driven to swing by alternating left and right pulling and rolling of the cloth, replacing the scraping and cleaning method of the traditional rigid seed scraper. During the swing, the buffer spring absorbs the impact, allowing the seedlings to complete the posture adjustment and separation of excess seedlings in a state of no collision and no compression. From the source to the seed cleaning process, flexible protection of seedlings is achieved, which greatly reduces mechanical damage.

[0023] This invention achieves a contactless transition from seed collection to sowing by alternately opening and closing air supply valves on both sides, allowing the seed collection trough to adsorb seeds under negative pressure in the adsorption zone and to blow seeds off under positive pressure in the sowing zone. The negative and positive pressures are supplied by independent air sources and do not interfere with each other. The mechanical linkage between the rotation position of the rotating drum and the opening and closing of the valves ensures adsorption stability and sowing reliability. After being sorted through the selection holes, the seeds fall directly into the seed collection trough and are then blown off to the sowing tube under positive pressure. Throughout the process, the seed movement trajectory is controllable and the landing point is precise. Compared with the traditional gravity free fall method, this effectively reduces the impact of airflow disturbance on the landing point and ensures uniform plant spacing and consistent sowing depth.

[0035] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0037] like Figures 1-10 The intelligent agricultural seeding device shown includes a bracket 1. A moving mechanism is connected to the middle of one side of the bracket 1. The moving mechanism is used to drive the device to move. Support plates 6 are connected to both sides of the upper end of the bracket 1. A seed storage box 7 is connected to the upper part between the two support plates 6. A V-shaped plate 9 is connected to the lower part of the seed storage box 7. A feeding port 10 is evenly opened on one side of the V-shaped plate 9.

[0038] The V-shaped plate 9 adopts an inclined structure design, which facilitates the automatic gathering of the seeds to a lower position under the action of gravity and discharge through the discharge port 10. The seeds in the seed storage box 7 fall into the V-shaped plate 9 through the discharge pipe 8, and then gather towards the center along the inner wall of the V-shaped plate 9. They are then guided to the discharge port 10 by the guide plate 11, realizing the initial centralized feeding of the seeds.

[0039] A sorting mechanism is connected above the V-shaped plate 9. The sorting mechanism is located directly below the discharge pipe 8. The sorting mechanism includes a winding motor 12. The output ends of the two winding motors 12 are connected to winding rollers 13. The outer walls of the two winding rollers 13 are wrapped with tension cloth 14. The lower ends of the two tension cloths 14 are connected to the sorting plate 15.

[0040] The winding motor 12 is a servo motor, which can precisely control the rotation angle and speed of the winding roller 13, thereby adjusting the tension of the tension cloth 14. When the two winding motors 12 rotate synchronously in opposite directions, one side winds up and the other side releases, driving the sorting plate 15 to swing left and right around its axis, realizing the shaking of the seed into the hole and the separation of excess seed.

[0041] A blocking mechanism is connected below the selection plate 15. A seeding mechanism is connected to one side of the V-shaped plate 9 corresponding to multiple feeding ports 10. The seeding mechanism is used to transport the seeds discharged from the feeding ports 10 to the soil. The seeding mechanism includes a connecting cylinder 24. A rotating cylinder 26 is rotatably connected inside the connecting cylinder 24. Intelligent auxiliary mechanisms are connected to both ends of the rotating cylinder 26. The intelligent auxiliary mechanisms prevent the seeds from having hard friction with the inner wall of the connecting cylinder 24.

[0042] Multiple seed-taking grooves 27 are evenly distributed around the outer wall of the rotating drum 26. The shape of the seed-taking grooves 27 matches the shape of the buds. Each seed-taking groove 27 can only hold two or three buds. When the rotating drum 26 rotates, the seed-taking grooves 27 pass under the guide frame 25 to receive the buds in sequence, and then rotate to the seed outlet to release the buds, thus realizing the transportation of the buds.

[0043] The intelligent auxiliary mechanism includes mounting plates 28, two mounting plates 28 are respectively mounted to both ends of the rotating drum 26, and a vent pipe 29 is connected between the two mounting plates 28. A venting mechanism is connected to both ends of the two mounting plates 28.

[0044] The ventilation pipe 29 is distributed along the axis of the rotating drum 26 and is connected to the ventilation groove 31 on the back of each seed collection groove 27. Negative or positive pressure gas is introduced into the ventilation pipe 29 through the ventilation mechanism, so that the seed collection groove 27 generates an adsorption force or a blowing force, thereby achieving stable adsorption of the buds and precise seeding.

[0045] A seeding tube 43 is evenly connected to one side of the lower end of the connecting tube 24. One side of the seeding tube 43 is connected to one side of the moving mechanism through the mounting frame 44. A stabilizing wheel 45 is rotatably connected to one side of the mounting frame 44.

[0046] The stabilizing wheel 45 remains in contact with the ground as the device moves, providing stable support for the seeding tube 43, preventing the seeding tube 43 from shaking during the sowing process, and ensuring that the seeds fall accurately into the sowing furrow.

[0047] like Figure 1 As shown: The moving mechanism includes a pulling frame 2, one end of which is connected to the middle of one side of the bracket 1. Rollers 3 are rotatably connected to both sides of the bracket 1. A support frame 4 is connected to one side of the bracket 1. One side of the support frame 4 is connected to multiple mounting brackets 44. Guide rods are evenly connected to one side of the support frame 4. Guide wheels 5 are rotatably connected to one side of the two guide rods.

[0048] The traction frame 2 is used to connect with the traction equipment, and the traction device moves as a whole. The roller 3 has good shock absorption performance and can absorb the vibration caused by uneven ground, ensuring the stability of the sowing device when operating in the field. The guide wheel 5 rolls along the sowing direction to keep the device balanced during the movement.

[0049] like Figures 2-4 As shown: The lower end of the seed storage box 7 is connected to the discharge pipe 8, and the lower end of the discharge pipe 8 is connected to the discharge valve;

[0050] The discharge valve is an electric butterfly valve. By controlling its opening and closing timing and opening degree, the seed storage box 7 can be quantitatively fed to the V-shaped plate 9, avoiding excessive feeding at one time and causing seed accumulation in the V-shaped plate 9.

[0051] V-shaped plate 9 is located between two support plates 6. The lower end of the inner wall of V-shaped plate 9 is connected to a guide plate 11 on the side corresponding to the feeding port 10. There are two guide plates 11 at each feeding port 10. The two guide plates 11 are arranged in a V-shape to guide the seedlings to the feeding port 10.

[0052] The V-shaped structure of the guide plate 11 forms a constricted channel, allowing the seeds to converge towards the center along the inner wall of the guide plate 11 under the action of gravity and fall precisely into the discharge port 10, thus preventing the seeds from accumulating and remaining at the bottom of the V-shaped plate 9.

[0053] There are two sets of winding motors 12. The two winding motors 12 are connected to one side of one of the support plates 6. The output ends of the two winding motors 12 extend through to the corresponding support plate 6. The winding motors 12 are servo motors, which can precisely control the rotation angle and speed of the winding roller 13. The two sets of winding motors 12 are controlled independently to meet the swing requirements under different working conditions.

[0054] The sorting plate 15 is located above the V-shaped plate 9. The upper end of the sorting plate 15 is provided with sorting holes 16 above multiple feeding ports 10. The diameter of the sorting holes 16 is slightly larger than the particle size of the seed, ensuring that each sorting hole 16 can hold two or three seedlings.

[0055] like Figures 2-5 As shown: The two ends of the selection plate 15 are respectively located between two support plates 6 and rotate. The middle of each end of the two selection plates 15 is connected to a rotating rod. The two ends of the two rotating rods extend through to one side of the corresponding support plate 6. The rotating rods are rotatably connected to the support plate 6 through bearings to ensure the flexibility and stability of the selection plate 15 when swinging. The two rotating rods are connected to a buffer mechanism. The two buffer mechanisms are respectively fixed to one side of the two support plates 6. The buffer mechanism is used to absorb the impact energy when the selection plate 15 swings to the extreme position to prevent the selection plate 15 from having a rigid collision with the support plate 6. At the same time, it provides auxiliary elastic force for the selection plate 15 to reset. The buffer mechanism includes a buffer plate 17, which is fixed to the outer wall of the rotating rod. The support plate 6 is connected to the buffer plate 17 through a fixed block with a buffer ring 18. The upper and lower ends of the buffer plate 17 slide along the outer wall of the buffer ring 18. The outer wall of the buffer ring 18 is fitted with a buffer spring 19. There are four sets of buffer springs 19, which are respectively connected to the upper and lower sides of the buffer plate 17 to buffer the buffer plate 17.

[0056] When the selection plate 15 swings to the left, the buffer plate 17 rotates counterclockwise with the rotating rod, compressing the upper buffer spring 19, which stores energy. When the selection plate 15 swings to the right, the buffer plate 17 compresses the lower buffer spring 19. The elasticity of the buffer spring 19 causes the selection plate 15 to experience gradually increasing resistance during the swing, achieving flexible buffering and avoiding impact damage to the buds.

[0057] like Figures 4-6 As shown: The blocking mechanism includes a baffle 20, which slides below the selection plate 15. The baffle 20 blocks multiple selection holes 16. Below the selection plate 15, at both ends of the baffle 20, there are housings 21 connected. One side of the inner wall of each housing 21 is connected to an electric telescopic rod 22. One end of each electric telescopic rod 22 is slidably connected to a moving plate 23. One end of each moving plate 23 extends through to one side of the corresponding housing 21 and is connected to both ends of the baffle 20.

[0058] The baffle 20 is in close contact with the lower surface of the selection plate 15. When the baffle 20 is in the closed position, the lower end of the selection hole 16 is closed and the seed is temporarily stored in the selection hole 16. When the baffle 20 is opened, the seed falls from the lower end of the selection hole 16 under the action of gravity and enters the guide frame 25.

[0059] When it is necessary to release the seedlings, the electric telescopic rod 22 extends, pushing the moving plate 23 to slide the baffle 20 and open the selection hole 16. When it is necessary to close, the electric telescopic rod 22 retracts, and the baffle 20 resets and closes. The stroke of the electric telescopic rod 22 matches the opening width of the selection hole 16, which can achieve a rapid response and ensure that the timing of seedling release is precisely synchronized with the position of the seed-taking groove 27 of the rotating drum 26.

[0060] like Figures 7-8 As shown: One side of the connecting cylinder 24 is connected to one side of the V-shaped plate 9 via connecting blocks. A guide frame 25 is connected to multiple feeding ports 10 on one side of the connecting cylinder 24. One end of each guide frame 25 is connected to one side of the V-shaped plate 9. The guide frame 25 has a funnel-shaped structure, with its upper end aligned with the feeding port 10 of the V-shaped plate 9 and its lower end aligned with the seed-taking groove 27 on the outer wall of the rotating cylinder 26. The inner wall of the guide frame 25 is smooth to ensure smooth seed bud drop and prevent jamming. Seed-taking grooves 27 are circumferentially connected to the outer wall of the rotating cylinder 26, with several seed-taking grooves 27 connected to multiple guide frames on one side. Corresponding to one end of 25, the seed-taking grooves 27 are evenly distributed around the circumference of the rotating drum 26, and their number matches the number of the feeding ports 10. The cross-sectional shape of the seed-taking grooves 27 is semi-circular, and the size is adapted to the seed particle size. Each seed-taking groove 27 can hold two or three seed particles. When the rotating drum 26 rotates, the seed-taking grooves 27 pass under the guide frame 25 in sequence and receive the seed particles falling from the feeding ports 10. The connecting cylinder 24 has a seed-feeding port on one side corresponding to one side of several seed-taking grooves 27. One end of multiple seed-feeding tubes 43 is located at multiple seed-feeding ports on one side of the connecting cylinder 24.

[0061] The seed inlet is located at the bottom of the connecting cylinder 24, corresponding to the rotation trajectory of the seed taking groove 27. When the seed taking groove 27 rotates to the seed inlet position carrying the seed, the seed falls out of the seed taking groove 27 under positive pressure and falls into the seed inlet tube 43. After being guided by the seed inlet tube 43, it falls into the sowing furrow.

[0062] like Figure 9 As shown: There are two sets of mounting plates 28 and five sets of vent pipes 29. The five vent pipes 29 are distributed circumferentially inside the rotating drum 26. The five sets of vent pipes 29 are arranged parallel to each other along the axis of the rotating drum 26. Each set of vent pipes 29 corresponds to the circumferential position of a seed-taking groove 27. Ventilation grooves 31 are opened on one side of the inner wall of the rotating drum 26 corresponding to the multiple seed-taking grooves 27. Installation pipes 30 are connected to one side of the multiple vent pipes 29 corresponding to the multiple ventilation grooves 31. One end of the multiple installation pipes 30 is inserted into the ventilation groove 31. The seed-taking groove 27 and the ventilation groove 31 are connected through a filter block, so that gas is introduced into the seed-taking groove 27 through the ventilation groove 31.

[0063] The cross-sectional area of ​​the ventilation groove 31 is smaller than the bottom area of ​​the seed collection groove 27, so that the gas is concentrated on the bottom of the seed, improving the efficiency of adsorption or blowing. The filter block is made of porous metal with a pore size smaller than the seed particle size, which can prevent the seed from being sucked into the ventilation groove 31 while ensuring smooth gas flow.

[0064] like Figures 8-10 As shown: The ventilation mechanism includes a connecting pipe 32. The connecting pipes 32 of the two ventilation mechanisms are respectively connected to one side of the two mounting plates 28. The outer surface of the connecting pipe 32 is connected to an air supply pipe 33. There are five sets of air supply pipes 33. The five air supply pipes 33 of the two ventilation mechanisms are respectively connected to both ends of five ventilation pipes 29. An air supply valve 34 is connected to one side of the outer wall of the multiple air supply pipes 33.

[0065] Connecting pipe 32 serves as the main gas collection pipe, distributing gas from the external gas source to five gas delivery pipes 33, which then send the gas into each ventilation pipe 29. The gas delivery valve 34 is a solenoid valve used to control the opening and closing of the gas path in the corresponding ventilation pipe 29. When the left gas delivery valve 34 is open and the right is closed, the negative pressure on the left is transmitted to the seed collection trough 27 through the ventilation pipe 29 to adsorb the buds. When the right gas delivery valve 34 is open and the left is closed, the positive pressure on the right is transmitted to the seed collection trough 27 through the ventilation pipe 29 to blow off the buds. By alternately opening and closing the gas delivery valves 34 on both sides, the gas pressure switching of the seed collection trough 27 at different work positions can be achieved.

[0066] A frame 35 is connected to one side of the upper end of the connecting cylinder 24. A drive motor 36 is connected to one side of the inner wall of the frame 35. A gear 37 is connected to the output end of the drive motor 36. A gear ring 38 is meshed with the lower end of the gear 37. The gear ring 38 is connected to the outer wall of one of the connecting pipes 32. A slide rod 42 is connected to one side of the outer wall of the other connecting pipe 32. A slip ring 41 is connected to the outer wall of the connecting cylinder 24 at the locations corresponding to the multiple slide rods 42. The multiple slide rods 42 slide inside the slip ring 41 respectively.

[0067] Driven by the drive motor 36, the meshing transmission of the gear 37 and the gear ring 38 drives the connecting pipe 32 and the mounting plate 28, the vent pipe 29 and the rotating drum 26 fixed thereto to rotate synchronously, so as to realize the continuous rotation of the rotating drum 26; the slide rod 42 and the slide ring 41 form a rotational sliding fit, so that the connecting pipe 32 on the other side can maintain the connection with the fixed pipe 40 when the rotating drum 26 rotates.

[0068] One end of each of the connecting pipes 32 of the two ventilation mechanisms is connected to a rotary joint 39, and one end of each of the two rotary joints 39 is connected to a fixed pipe 40. One end of each of the two fixed pipes 40 extends through to both ends of the connecting cylinder 24. A negative pressure pump 46 is connected to the upper part of one side of one of the support plates 6 through a first mounting box. The output end of the negative pressure pump 46 is connected to one end of one of the connecting pipes 32. An air pump 47 is connected to the upper part of the other support plate 6 through a second mounting box. The output end of the air pump 47 is connected to one end of the other connecting pipe 32. Filter screens are embedded on one side of the first mounting box and the second mounting box to facilitate air intake and exhaust.

[0069] The rotary joint 39 allows the connecting pipe 32 to maintain airflow communication with the fixed pipe 40 while rotating. The fixed pipe 40 is fixedly connected to the end of the connecting cylinder 24 as a static interface for the airflow. The negative pressure pump 46 provides adsorption force to the left ventilation mechanism, and the air pump 47 provides blowing force to the right ventilation mechanism. The negative pressure pump 46 and the air pump 47 work independently and do not interfere with each other, ensuring the stability of the adsorption and seeding process.

[0070] A smart agricultural sowing method includes the following steps:

[0071] S1: Load rice seedlings into seed storage box 7, open the discharge valve, and the seedlings fall into V-shaped plate 9 and are evenly distributed. Two winding motors 12 drive winding rollers 13 and pulling cloth 14 to keep the selection plate 15 horizontal, and the seedlings fall into selection holes 16. Each selection hole 16 can hold two or three seedlings.

[0072] S2: The winding motor 12 alternately winds up the pulling cloth 14 on both sides, driving the selection plate 15 to swing back and forth so that the buds enter the selection hole 16 in an orderly single layer.

[0073] S3: When the selection plate 15 swings to the preset tilt angle, the blocking mechanism opens the selection hole 16, allowing the seed to fall into the seed-taking groove 27 of the seed-laying mechanism; by controlling the air path, negative pressure is provided to absorb the seed when the seed-taking groove 27 receives the seed, and positive pressure is provided to blow it out when the seed is placed, thus completing the sowing.

[0074] The device is equipped with a mobile power supply, which is electrically connected to the winding motor 12, electric telescopic rod 22, drive motor 36, negative pressure pump 46 and air pump 47, etc., to provide working power for each electrical device in the device, so that the device does not need an external power supply when operating in the field, and can achieve independent power supply and flexible operation.

[0075] It should be noted that the specific circuit connections and control methods of the actuators and controllers, such as the winding motor 12, electric telescopic rod 22, drive motor 36, negative pressure pump 46, air pump 47, air supply valve 34, and related controllers involved in the embodiments of the present invention, are all conventional technical means in the field and belong to the scope of the prior art.

[0076] Working principle: The device is connected to the traction equipment through the pulling frame 2 and moves forward smoothly under the support of the roller 3 and guide wheel 5. When the operation starts, the discharge valve at the lower end of the discharge pipe 8 is opened, and the rice sprouts in the seed storage box 7, which have been soaked, germinated and dried to the state of "wet inside and dry outside, not sticky to the touch", fall above the selection plate 15.

[0077] Two sets of winding motors 12 operate alternately. When the left winding motor 12 winds up and the right winding motor 12 releases, the left pulling cloth 14 tightens and the right pulling cloth 14 relaxes, driving the selection plate 15 to tilt to the left. Conversely, when the right side winds up and the left side releases, the selection plate 15 tilts to the right. During the swinging process, the buds enter the selection hole 16, and the excess buds slide down the upper surface of the selection plate 15 into the V-shaped plate 9 to continue circulating, shaking off the excess buds in the hole that exceed the set number, so that each selection hole 16 stably holds two to three buds.

[0078] The buffer plate 17 on the outer wall of the rotating rod slides along the buffer ring 18 as the selection plate 15 swings, compressing the buffer spring 19 on the corresponding side. The spring force absorbs the swing impact, making the selection plate 15 move smoothly and gently. Through alternating left and right swings, the retained buds complete the posture adjustment without collision or compression under the flexible protection of the pulling cloth 14.

[0079] When the selection plate 15 tilts to the right to the set angle, the electric telescopic rod 22 extends, pushing the moving plate 23 to slide the baffle 20, opening the lower end of the selection hole 16. Groups of buds fall from the selection hole 16 under the action of gravity and fall into the V-shaped plate 9. After being guided by the guide plate 11, they are evenly distributed to each discharge port 10 and guided by the guide frame 25 to fall into the seed trough 27 on the outer wall of the rotating drum 26.

[0080] At this time, the left gas supply valve 34 is opened and the right gas supply valve 34 is closed. The negative pressure generated by the negative pressure pump 46 is transmitted to the seed collection trough 27 through the left connecting pipe 32, gas supply pipe 33, ventilation pipe 29, installation pipe 30 and ventilation groove 31, adsorbing the group of buds into the seed collection trough 27. The filter block between the seed collection trough 27 and the ventilation groove 31 prevents the buds from being sucked into the air path, ensuring stable and reliable adsorption.

[0081] The drive motor 36 drives the gear ring 38 to rotate through the gear 37, which drives the connecting pipe 32, the mounting plate 28, the ventilation pipe 29 and the rotating drum 26 to rotate synchronously. The seed collection trough 27, which adsorbs the group of buds, rotates with the rotating drum 26. When it rotates to the seed inlet position at the lower end of the connecting drum 24, the left air supply valve 34 closes and the right air supply valve 34 opens. The positive pressure generated by the air pump 47 is transmitted to the ventilation trough 31 through the right connecting pipe 32, the air supply pipe 33, the ventilation pipe 29 and the mounting pipe 30, and positive pressure gas is introduced into the seed collection trough 27 to blow the group of buds off.

[0082] After being guided by the seeding tube 43, the blown-down group of buds falls precisely into the sowing furrow. The stabilizing wheel 45 on one side of the mounting frame 44 remains in contact with the ground as the device moves, providing stable support for the seeding tube 43, preventing it from shaking, and ensuring accurate landing position.

[0083] The rotating drum 26 rotates continuously, and the seed picking trough 27 goes through a cycle of receiving, adsorbing, rotating, and sowing in sequence. The sorting plate 15 swings continuously under the drive of the winding motor 12, constantly queuing and cleaning the seedlings. The baffle 20 opens and closes synchronously with the rotating drum 26 under the drive of the electric telescopic rod 22, realizing the orderly connection of the entire process from queuing to sowing of seedlings. Throughout the process, the seedlings are always in a single layer of orderly state, with two to three seeds sown in each hole. There is no accumulation or squeezing, no mechanical scraping, and no rigid collision. This ensures low-damage sowing and improves the planting success rate through group sowing, realizing efficient, precise, and reliable intelligent sowing operations.

[0084] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
