Description

Technical Field

[0001] This invention relates to the field of agricultural power machinery technology, specifically a seed-planting machine for seed research and cultivation. Background Technology

[0002] Seeding machines, also known as hill seeders, are an indispensable seed research and cultivation method in modern facility agriculture. They are commonly used machines for sowing in modern intelligent agricultural power machinery. By sowing seeds into the holes of a substrate-filled seed tray, they provide seedlings with a uniform water, fertilizer, air, and heat environment, thereby significantly improving germination rate and seedling uniformity.

[0003] When sowing seeds using a seed-spotting machine, soil is first placed in the seed tray, and planting holes are pressed out of the soil by the protrusions. Then, the seeds are placed into the pressed-out planting holes by the seed-spotting structure, and finally, the soil is covered to complete the seed-spotting operation.

[0004] In mechanized automatic seeding operations, the seeding steps are: pressing out planting holes—sowing—covering with soil. However, placing seeds into the holes after pressing out the planting holes is a process that requires extremely high timing coordination. When there is a dynamic mismatch between the seed dispensing speed and the conveyor belt speed, whether the seed dispensing is too fast and the conveyor belt is lagging behind, or the conveyor belt is ahead and the seed dispensing is slow, the seed landing point will deviate from the preset hole center, causing the seeds to fall on the hole wall, outside the hole, or even between two holes, ultimately resulting in missed sowing (empty holes) or double sowing (multiple seeds piled up), which seriously affects the sowing quality and the consistency of subsequent seedling cultivation. Moreover, the operation steps are cumbersome and require the use of corresponding mechanical equipment.

[0005] In addition, the current method of feeding the seed trays still mainly relies on manual labor to place the seed trays one by one on the conveyor belt. This method is not only labor-intensive and inefficient, but also makes it difficult to ensure that the spacing between each placement is uniform and consistent. The lateral positioning of the seed trays on the conveyor belt is also often inaccurate.

[0006] Based on this, the present invention provides a seed-planting machine for seed research and cultivation to solve the above problems. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides a seed-planting machine for seed research and cultivation. The present invention has a novel structure and ingenious design, and effectively solves the technical problems of seed drop deviation caused by speed inconsistency and low efficiency of manual tray placement.

[0008] A seed-planting machine for seed research and cultivation includes a frame. Two supports are fixedly connected to the top of the frame. A cylinder capable of lifting and rotating is arranged between the two supports. Multiple suction nozzles communicating with the inside of the cylinder are fixedly connected to the surface of the cylinder. A ventilation pipe is fixedly connected inside the ventilation cylinder. A support plate is fixedly connected to the bottom of the ventilation pipe. The support plate has ventilation holes. The ventilation pipe cooperates with the suction nozzles through the ventilation holes on the support plate. Rotating rings are fixedly connected to both ends of the cylinder. Multiple rotating rods are fixedly connected to one side of each of the two rotating rings. Support blocks are fixedly connected to the sides of the two supports that are close to each other. Each of the two rotating rings cooperates with the support block through the rotating rods on one side.

[0009] Preferably, each of the two supports is provided with a sliding groove, and a ventilation cylinder that can be raised and lowered is provided in the two sliding grooves. A cylinder body is rotatably connected to the ventilation cylinder, and the ventilation cylinder and the cylinder body are connected.

[0010] Preferably, a fixed seat is slidably connected inside the slide groove, the ventilation duct is fixedly connected to the fixed seat, and a limiting rod that slides on the slide groove is fixedly connected to the top of the fixed seat, with a main spring sleeved on the limiting rod.

[0011] Preferably, a driven sprocket is fixedly connected to the rotating ring, and a driving sprocket is provided on one side of the bracket. The driving sprocket and the driven sprocket are connected by a chain and a swing sprocket.

[0012] Preferably, a feeding hopper is fixedly connected to one side of each of the two supports, a guide hopper is fixedly connected to one side of the feeding hopper, and a conveying cylinder is fixedly connected to the bottom of the guide hopper.

[0013] Preferably, the top two sides of the feeding hopper are fixedly connected to a frame, and each frame is equipped with a support shaft that can be raised and lowered. A guide wheel is fixedly connected to the support shaft, and a rotating shaft is rotatably connected inside the feeding cylinder. A spiral blade is fixedly connected to the rotating shaft.

[0014] Preferably, a material tray is fixedly connected to the frame, four limiting frames are fixedly connected to the top of the material tray, a limiting frame is fixedly connected to the top of the material tray, and a lower partition plate and an upper partition plate are slidably connected inside the limiting frame.

[0015] Preferably, a main slide rod is fixed at the lower end of the material tray, a main slide seat slides on the main slide rod, a secondary slide rod is fixed at the lower end of the main slide seat, a secondary slide seat slides on the secondary slide rod, a push frame is fixed on the secondary slide seat, and a push plate is fixed on the push frame.

[0016] Preferably, a fixed shaft is fixedly connected to one side of the push frame, a rotating seat is rotatably connected to the fixed shaft, a sliding rod is fixedly connected to the rotating seat, the sliding rod is slidably fitted with a rotatable sliding seat, and an auxiliary spring is sleeved on the sliding rod.

[0017] The present invention has the following technical effects.

[0018] 1. This invention uses a main spring, rotating ring, rotating rod, and support block to drive the cylinder to rise smoothly and descend rapidly during rotation. This causes the suction nozzle on the cylinder to press planting holes into the soil of the seedling tray. The suction nozzle, ventilation cylinder, ventilation pipe, and support plate adsorb the seeds and carry them down with the suction nozzle to contact the seedling tray. As the seeds fall onto the seedling tray, the suction nozzle presses them down to form planting holes, completing the sowing operation. In addition, it can effectively clean the residue in the suction nozzle channel, ensuring the stability and reliability of subsequent seed adsorption, and simplifying the sowing operation steps, eliminating the need for cumbersome corresponding tools.

[0019] 2. This invention uses a feeding hopper, a guide hopper, and a guide wheel to transport seeds to one side of the guide hopper and allow them to slide down, continuously supplying the rotating suction nozzle with seeds, thereby improving the suction nozzle's adsorption effect on seeds. Through a feeding cylinder, a rotating shaft, and spiral blades, seeds that are not adsorbed and fall into the feeding cylinder are transported out, realizing the recycling of seeds and avoiding waste.

[0020] 3. This invention uses a limiting frame, a lower partition plate, an upper partition plate, and an electric push rod to separate the stacked cavities layer by layer, facilitating subsequent retrieval. Through the main slide rod, secondary slide rod, push frame, and push plate, the separated cavities slide sequentially onto the conveyor belt via the guide plate on one side of the tray, achieving an orderly and continuous tray feeding process, improving the efficiency of cavity tray transportation, reducing labor intensity, and ensuring uniform spacing for each placement.

[0021] 4. This invention uses a hopper, screening frame, baffle and buffer sleeve to screen the soil, effectively removing clumps and larger impurities to obtain uniform and fine qualified soil. This soil is then filled into the seed trays to provide good substrate conditions for the sowing operation, which is beneficial to seed growth. Attached Figure Description

[0035] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 11The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0036] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0037] This invention relates to a seed-planting machine for seed research and cultivation, comprising a frame 1, with two supports 3 fixedly connected to the top of the frame 1, and a cylindrical body 10 capable of lifting, lowering, and rotating between the two supports 3. Multiple suction nozzles 11 are fixedly connected to the surface of the cylindrical body 10, the shape of which is the same as the shape of the planting holes to be pressed into the seedling tray. All suction nozzles 11 are connected to the interior of the cylindrical body 10. A filter screen is installed inside the air intake channel of the suction nozzles 11. A ventilation pipe 9 is fixedly connected inside a ventilation cylinder 5, and a support plate 17 is fixedly connected to the bottom of the ventilation pipe 9. The other side of the support plate 17 passes through the ventilation cylinder 5 and slides against the inner wall of the cylindrical body 10. Multiple ventilation holes are provided on the support plate 17, and the ventilation pipe 9 engages with the suction nozzles 11 through the ventilation holes on the support plate 17.

[0038] Both ends of the cylinder 10 are fixedly connected to rotating rings 12. Multiple rotating rods 13 are fixedly connected to one side of each of the two rotating rings 12. The multiple rotating rods 13 are evenly distributed on the rotating rings 12 and correspond to the position of the suction nozzle 11. Support blocks 15 are fixedly connected to the sides of the two supports 3 that are close to each other. Both support blocks 15 are right-angled triangles. Both rotating rings 12 cooperate with the support blocks 15 through the rotating rods 13 on one side. The upper edge of the support block 15 is located in the middle of the support 3, so that when the rotating rod 13 is separated from the support block 15, the suction nozzle 11 faces downward.

[0039] Both supports 3 are provided with sliding grooves 4, and ventilation cylinders 5 that can be raised and lowered are provided in the two sliding grooves 4. A cylinder body 10 is rotatably connected to the ventilation cylinder 5. The cylinder body 10 is located between the two supports 3. Multiple ventilation holes are provided between the connection position of the ventilation cylinder 5 and the cylinder body 10, so that the cylinder body 10 and the ventilation cylinder 5 are in a connected state.

[0040] It should be noted that an air pump is connected to one side of the ventilation duct 5 to draw air into the ventilation duct 5, and an air pump is connected to one end of the ventilation pipe 9 to fill the ventilation pipe 9 with air. The air pump and the air pump are existing technologies, so they are not described in detail in this article.

[0041] In this embodiment, during use, the rotating ring 12 is driven to rotate, which in turn drives the cylinder 10 to rotate synchronously. At the same time, multiple rotating rods 13 move accordingly. During the rotation of the rotating rods 13, one of the rotating rods 13 on the rotating ring 12 first contacts the lower position of the top of the support block 15. As the rotating ring 12 continues to rotate, the rotating rod 13 gradually rises along the top surface of the support block 15, thereby driving the ventilation cylinder 5 and the cylinder 10 to rise synchronously. While the ventilation cylinder 5 rotates and rises, the air pump draws air from the inside of the ventilation cylinder 5. Since the ventilation cylinder 5 and the cylinder 10 are interconnected, a negative pressure state is synchronously formed inside both, thereby adsorbing and fixing the seeds through the suction nozzle 11 on the cylinder 10.

[0042] When the rotating rod 13 moves to the highest position of the support block 15, a row of suction nozzles 11 on the cylinder 10 aligns with the seed tray below. At this time, the air supply pipe on the cylinder 10 that connects to the suction nozzles 11 is aligned with the ventilation hole on the support plate 17. The air pump blows air to this position through the ventilation pipe 9. The gas is sprayed out through the ventilation hole to the suction nozzles 11, blowing the seeds down into the seed tray. At the same time, the internal channels of the suction nozzles 11 are blown clean. After the rotating rod 13 passes the support block 15, the ventilation cylinder 5 drives the cylinder 10 to fall quickly, so that the suction nozzles 11 contact the top of the seed tray and press down on the seeds. While pressing out the planting hole, the seeds are simultaneously pressed into the planting hole, thus completing the sowing operation.

[0043] As an example, a fixed seat 6 is slidably connected in both slide grooves 4, and the two sides of the two ventilation cylinders 5 are respectively fixedly connected to the two fixed seats 6. A limit rod 7 is fixedly connected to the top of both fixed seats 6. The two limit rods 7 are slidably connected to the top of the slide grooves 4. A main spring 8 is sleeved on both limit rods 7. The main spring 8 is located between the top of the fixed seat 6 and the top of the slide groove 4.

[0044] A method for rotating the cylinder 10 is provided:

[0045] A driven sprocket 14 is fixedly connected to the rotating ring 12. A driving sprocket 16 is provided on one side of the bracket 3. The driving sprocket 16 and the driven sprocket 14 are connected by a chain and a swing sprocket. The chain drives the driving sprocket 16, the driven sprocket 14, the swing sprocket, and the spring to rotate. The swing sprocket is a movable tension wheel, and a spring assists in its reset when it moves. When the driven sprocket 14 changes displacement, the swing sprocket swings to adjust the displacement and realize the normal transmission of the driving sprocket 16 and the driven sprocket 14.

[0046] It should be noted that a geared motor is connected to the frame 1, and the drive sprocket 16 is connected to the end shaft of the geared motor. The geared motor is connected to a power supply and a controller. The geared motor, power supply and controller are existing technologies, so they are not described in detail in this article.

[0047] In this embodiment, during the planting operation, the reduction motor starts, driving the drive sprocket 16 to rotate. The drive sprocket 16 drives the driven sprocket 14 to rotate via the chain and the swing sprocket, which in turn drives the rotating ring 12 to rotate. The rotating ring 12 drives the rotating rod 13 to rotate synchronously until the rotating rod 13 contacts the lower position of the top of the support block 15. As the rotating ring 12 continues to rotate, the rotating rod 13 gradually slides and rises along the top surface of the support block 15, thereby driving the ventilation duct 5 and the cylinder 10 on it to rise synchronously. When the cylinder 10 rises, the swing sprocket moves to adjust, so as to ensure the normal transmission of the drive sprocket 16 and the driven sprocket 14.

[0048] During the upward movement of the ventilation cylinder 5, the fixed seats 6 at both ends move upward synchronously within the two sliding grooves 4. The limiting rod 7 on the fixed seat 6 slides upward along the top of the sliding groove 4, while compressing the main spring 8 located between the fixed seat 6 and the top of the sliding groove 4, causing the main spring 8 to undergo elastic deformation and generate a downward rebound thrust. When the rotating rod 13 moves to the highest point of the support block 15 and passes the support block 15, the two fixed seats 6 are only subjected to the downward elastic force of the main spring 8 and gravity, pushing the ventilation cylinder 5 and the cylinder body 10 to descend rapidly, so that the suction nozzle 11 on the cylinder body 10 can smoothly press out the planting hole on the seedling tray.

[0049] As an example, a mounting bracket 18 is fixedly connected to one side of each of the two brackets 3, and a feeding hopper 19 is fixedly connected between the two mounting brackets 18. A guide hopper 20 is fixedly connected to one side of the feeding hopper 19. The guide hopper 20 is inclined from top to bottom toward the cylinder 10, with the inclination angle being optimally between 15 and 30 degrees. A conveying cylinder 25 is fixedly connected to the bottom of the guide hopper 20, and a feed inlet is opened at the top of the conveying cylinder 25. The feed inlet is aligned with the working surface of the guide hopper 20.

[0050] As an example, the top two sides of the feeding hopper 19 are fixedly connected to a frame 21, and the top of the frame 21 is threaded with a fixing bolt. Each of the two frames 21 is provided with a support shaft 22 that can be raised and lowered. Both sides of the support shaft 22 are rotatably connected to a bearing seat. The bottom of the fixing bolt is rotatably connected to the top of the bearing seat on the support shaft 22. A guide wheel 23 is fixedly connected to the support shaft 22. The guide wheel 23 cooperates with the bottom of the inner wall of the feeding hopper 19. A rotating shaft 26 is rotatably connected inside the conveying cylinder 25. The rotating shaft 26 and the support shaft 22 are linked by a pulley and a belt 24. A spiral blade 27 is fixedly connected to the rotating shaft 26. The spiral blade 27 is located inside the conveying cylinder 25.

[0051] It should be noted that one end of the rotating shaft 26 is connected to a geared motor, which is connected to a power supply and a controller. The geared motor, power supply, and controller are existing technologies and therefore are not described in detail in this article.

[0052] In this embodiment, the worker places the seeds to be sown into the feeding hopper 19. After starting the reduction motor, the reduction motor drives the rotating shaft 26 to rotate, and drives the support shaft 22 to rotate synchronously through the belt 24. The support shaft 22 then drives the guide wheel 23 to rotate. The guide wheel 23 transfers the seeds on the feeding hopper 19 to the guide hopper 20. At the same time, during the conveying process, the accumulated seeds are limited and flattened, so that the seeds fall evenly onto the guide hopper 20. The seeds falling into the guide hopper 20 slide down its surface, thereby providing material for the suction nozzle 11. During the sowing process, when the suction nozzle 11 rotates to one side of the guide hopper 20, the seeds detach from the guide hopper 20 and are adsorbed onto the suction nozzle 11, completing the material feeding operation. The seeds that are not adsorbed continue to slide down along the guide hopper 20 and enter the conveying cylinder 25. When the rotating shaft 26 rotates, it drives the spiral blade 27 to rotate, conveying the seeds that fall into the conveying cylinder 25 and discharging them from one side of the conveying cylinder 25 for reuse.

[0053] As an example, two fixed frames 28 are fixedly connected to the frame 1, and a material tray 29 is fixedly connected to the two fixed frames 28. A guide plate 31 is fixedly connected to one side of the material tray 29. The height of the guide plate 31 gradually decreases from the position of the material tray 29 to the position away from the material tray 29. Four limiting frames 30 are fixedly connected to the top of the material tray 29. The four limiting frames 30 are all "L" shaped to limit the placement of the cavity tray. A limiting frame 32 is fixedly connected to the top of the material tray 29. Two moving slots are opened on the limiting frame 32. A lower partition plate 33 and an upper partition plate 34 are respectively in the two moving slots. The lower partition plate 33 is located below the upper partition plate 34. The side of the upper partition plate 34 near the cavity tray is a right-angled triangle. A bracket 35 is fixedly connected to one side of the material tray 29. Two electric push rods 36 are fixedly connected to the bracket 35. The output ends of the two electric push rods 36 are fixedly connected to one side of the lower partition plate 33 and the upper partition plate 34, respectively.

[0054] It should be noted that both electric actuators 36 are connected to a power supply and a controller. The power supply and controller are existing technologies and therefore are not described in detail in this article.

[0055] In this embodiment, during use, the operator places the acupuncture tray to be used between four limiting frames 30. The limiting frames 30 limit the acupuncture tray. The acupuncture tray enters the guide plate 31 through the slit on one side of the upper end of the material tray 29 at the lower end of the limiting frame 30. First, the output end of the electric push rod 36 on one side of the lower partition plate 33 extends, pushing the lower partition plate 33 to insert itself between the bottommost acupuncture tray and the second acupuncture tray below it. Then, the output end of the electric push rod 36 on one side of the upper partition plate 34 extends, driving the upper partition plate 34 to further insert itself between the two acupuncture trays along the lower partition plate 33. The upper partition plate 34 has a right-angled triangular structure on one side, which, in conjunction with the lower partition plate 33, can lift the second acupuncture tray and all the acupuncture trays above it upwards, separating them from the bottommost acupuncture tray for easy retrieval. When the last acupuncture tray is separated, the two electric push rods 36 are set to retract synchronously, driving the lower partition plate 33 and the upper partition plate 34 to retract and reset together, preparing for the subsequent separation operation of the acupuncture trays.

[0056] As an example, the bottom of the material tray 29 has two working slots 37, which are rectangular. A main slide rod 39 is fixedly connected to the bottom of the material tray 29. A main slide seat 40 is slidably connected to the main slide rod 39. A secondary slide rod 41 is fixedly connected to the bottom of the main slide seat 40. A secondary slide seat 42 is slidably connected to the secondary slide rod 41. A pusher frame 43 is fixedly connected to the secondary slide seat 42. The pusher frame 43 is shaped like a "U". Pusher plates 38 are fixedly connected to both sides of the top of the pusher frame 43. Anti-slip blocks are provided on the top of the two pusher plates 38. The two pusher plates 38 cooperate with the two working slots 37 respectively.

[0057] As an example, a mounting plate 49 is fixedly connected to the bottom of the material tray 29. A servo geared motor 50 is fixedly connected to one side of the mounting plate 49. A drive shaft 51 is fixedly connected to the output end of the servo geared motor 50. A sliding seat 47 is fixedly connected to the other end of the drive shaft 51. A fixed shaft 44 is fixedly connected to one side of the push frame 43. An "L"-shaped rotating seat 45 is rotatably connected to the fixed shaft 44. A sliding rod 46 is fixedly connected to the other side of the rotating seat 45. The sliding seat 47 is slidably connected to the sliding rod 46. An auxiliary spring 48 is sleeved on the sliding rod 46.

[0058] In this embodiment, for the cavity tray falling onto the material tray 29, the servo reduction motor 50 is started, driving the drive shaft 51 to rotate. The drive shaft 51 then drives the sliding seat 47 to rotate synchronously. When the sliding seat 47 rotates, it drives the sliding rod 46 to move. The push frame 43 and its fixed shaft 44 on one side rotate and engage with the rotating seat 45, causing the push plate 38 at the top of the push frame 43 to enter the working groove 37. When the top of the push plate 38 gradually contacts the bottom of the cavity tray, it engages the rotating seat 45 and the sliding seat. The auxiliary spring 48 between 47 is compressed, causing the auxiliary spring 48 to generate a reverse force. As the drive shaft 51 continues to drive the sliding seat 47 to rotate, the reverse force of the auxiliary spring 48 pushes the rotating seat 45, the push frame 43 on one side, and the push plate 38 above to move to one side. Through the friction between the anti-slip block on the top of the push plate 38 and the bottom of the cavity tray, the main sliding seat 40 is driven to slide on the main sliding rod 39. Through the push plate 38, the cavity tray is driven to slide on the material tray 29, so that it moves to the guide plate 31.

[0059] After the pusher plate 38 pushes the cavity tray to the predetermined position, the drive shaft 51 continues to drive the rotating seat 45 to rotate. The pusher frame 43 and its secondary sliding seat 42 slide on the secondary sliding rod 41, causing the pusher plate 38 to separate from the pushed cavity tray until it contacts the bottom of the new cavity tray again after one rotation, and then pushes it again. During the pushing process, the subsequent cavity trays push the cavity trays that are already located on the guide plate 31 in front, so that the cavity trays are arranged in sequence and move one by one to the conveying mechanism 2.

[0060] It should be noted that the servo geared motor is connected to a power supply and a controller, which are existing technologies and therefore not described in detail in this article.

[0061] As an example, a hopper 52 is fixedly connected to the frame 1, and a driven shaft 53 is rotatably connected to the hopper 52. The driven shaft 53 is located on the top side of the hopper 52, and a screening frame 54 is fixedly connected to the driven shaft 53. The screening frame 54 is located inside the hopper 52, and an adjustment groove is opened on the other side of the hopper 52. The screening frame 54 is placed at the bottom of the adjustment groove on the hopper 52. An outlet is opened at the lower end of the hopper 52 for the screened soil to slide out. One end of the driven shaft 53 passes through the hopper 52 and is fixedly connected to a baffle 55. A drive shaft 56 is rotatably connected to one side of the hopper 52, and a drive blade 57 is fixedly connected to the drive shaft 56. The drive blade 57 cooperates with the baffle 55. A buffer sleeve 58 is rotatably connected to the bottom of the screening frame 54, and the other end of the buffer sleeve 58 is rotatably connected to one side of the hopper 52.

[0062] As an example, a threaded cylinder 59 is fixedly connected to one side of the hopper 52. A threaded rod 60 is threadedly connected to the inside of the threaded cylinder 59. A slab plate 61 is rotatably provided at the bottom end of the threaded rod 60. The slab plate 61 is in the shape of "<" and is used to spread the soil that falls on the seed tray.

[0063] It should be noted that a material hopper 52 is also provided on the other side of the cylinder 10 to cover the pressed planting holes with soil. Since it is the same structure, it is not described in detail in the figure and text. A geared motor is also connected to one end of the drive shaft 56. The geared motor is connected to a power supply and a controller. The geared motor, power supply and controller are existing technologies, so they are not described in detail.

[0064] In this embodiment, during use, the worker places the soil required for planting on the screening frame 54. After starting the reduction motor, the reduction motor drives the drive shaft 56 to rotate, and the drive blades 57 on the drive shaft 56 rotate synchronously. When one of the drive blades 57 rotates to contact the baffle 55, it drives the baffle 55 and the driven shaft 53 to rotate, and the screening frame 54 rotates synchronously. At the same time, it stretches the buffer sleeve 58 below the screening frame 54. When the drive blade 57 rotates to disengage from the baffle 55, the buffer sleeve... 58 utilizes its own elastic restoring force to drive the screening frame 54 and driven shaft 53 to rotate in the opposite direction on the hopper 52 to reset. By driving the blades 57 to periodically contact and disengage from the baffle 55, the screening frame 54 rotates continuously to screen the soil on the screening frame 54, removing and separating the soil that is clumped or contains large impurities, thereby providing fine soil that meets the requirements for subsequent planting operations. Large pieces of soil enter the collection box, while small pieces of soil fall from below the screening frame 54 onto the hopper 52 and enter the seed tray.

[0065] As an example, the frame 1 is provided with two conveying mechanisms 2, and there is a gap between the two conveying mechanisms 2.

[0066] In this embodiment, the seedling tray is transported by two conveying mechanisms 2, and excess soil falling on the conveying mechanism 2 is discharged through the gap between the two conveying mechanisms 2, which facilitates subsequent use.

[0067] The conveyor is equipped with corresponding sensors, which work in conjunction with the controller to start and stop the acupuncture trays during operation. This is existing technology and will not be described in detail here.

[0068] Working principle of this invention:

[0069] In use, the stacked cavity trays are placed between the four limit frames 30. The electric push rod 36 drives the lower partition plate 33 and the upper partition plate 34 to be inserted between the bottommost cavity tray and the second cavity tray below, respectively, so that the bottommost cavity tray is separated from the stacked cavity trays. The separated cavity trays fall onto the material tray 29. The servo reduction motor 50 drives the pusher plate 38 to push them, so that the cavity trays on the material tray 29 move to the guide plate 31. Each cavity tray is pushed in turn, so that they fall onto the conveying mechanism 2 one by one for conveying.

[0070] The seedling tray moves to the bottom of the hopper 52 first with the conveying mechanism 2. The drive blade 57 on the drive shaft 56 moves the baffle 55 to rotate and is reset by the pulling action of the buffer sleeve 58, thereby driving the driven shaft 53 to rotate back and forth, causing the screening frame 54 to swing back and forth to screen the placed soil. The screened soil falls from the bottom of the hopper 52 onto the seedling tray, and then the soil is leveled by the spreading plate 61 on one side of the hopper 52. The leveling height can be adjusted by rotating the threaded rod 60 on the threaded cylinder 59.

[0071] After the soil filling is completed, the seedling tray continues to move with the conveying mechanism 2 to the bottom of the cylinder 10. The staff places the seeds to be planted on the upper hopper 19. The seeds are pushed to the guide hopper 20 by the guide wheel 23 and slide down along the guide hopper 20. At this time, the cylinder 10 is evacuated so that the suction nozzle 11 can adsorb and fix the seeds. When the suction nozzle 11 rotates to the position directly below and is aligned with the ventilation hole on the support plate 17, air is blown into the ventilation pipe 9 so that the seeds are blown from the suction nozzle 11 onto the seedling tray.

[0072] After the seeds fall into the seedling tray, the cylinder 10 falls rapidly, the suction nozzle 11 contacts the seeds and applies downward pressure, pressing the seeds into the planting holes on the seedling tray at the same time. After pressing, the cylinder 10 rises again, realizing the synchronous operation of pressing holes and sowing. After sowing is completed, the seedling tray continues to move to the bottom of the subsequent material bin 52, and another layer of soil is covered on the planting holes, thus completing all sowing operations.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
