Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and more specifically, to a corn fertilization device and method. Background Technology

[0002] Corn fertilization and planting equipment is a key agricultural equipment for achieving precise and efficient corn planting. Its performance is directly related to the emergence rate, fertilizer utilization rate and final yield.

[0003] Currently, traditional corn planting mainly uses the seeding wheel for spot sowing. However, this equipment still has shortcomings in its use. First, during the process of dropping the seeds after they leave the seeding wheel, they are easily affected by field airflow and soil surface protrusions, causing them to bounce and roll, resulting in seeds deviating from the planting hole, causing missed sowing and uneven plant spacing.

[0004] Secondly, the seeder reel itself has a single function, only capable of seeding. In actual operation, it must be used in conjunction with a separate hole-opening device to first open seed holes on the soil surface, and then the seeder reel is used to place the seeds. In addition, a separate fertilization device is required to apply fertilizer next to the seed holes. This step-by-step mode of opening holes, sowing seeds, and then fertilizing not only increases the complexity and manufacturing cost of the equipment, but also, due to misalignment between the equipment, leads to deviations in the distance between the fertilization point, the seed hole point, and the sowing point, affecting the fertilization effect and even causing the risk of seedling burn. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a corn fertilization device and method that uses a measuring cylinder to directly insert seeds into the soil, avoiding the seed-dropping process. The seeds are protected within the measuring cylinder until they fall directly into the sowing hole, eliminating external interference, preventing missed sowing and uneven plant spacing, reducing equipment parts, lowering complexity and manufacturing costs, and ensuring consistent distances between the fertilization point, seed hole, and sowing point through mechanical linkage, avoiding fertilization deviations and the risk of seedling burn.

[0006] The present invention proposes the following technical solution: a corn fertilization device, including a fixing plate, an insert tube installed inside the fixing plate, a fertilizer tube fixedly connected to the inner wall of the fixing plate, the bottom of the insert tube having a semi-circular structure, and a through sliding hole opened at the bottom of the inner wall of the insert tube;

[0007] A measuring cylinder is slidably connected to the inner wall of the sliding hole, and at least one feed hole is opened on the outer circumference of the measuring cylinder.

[0008] The measuring cylinder is provided with a tray, and a rubber ring is fixedly connected to the outer circumference of the tray. The outer circumference of the rubber ring is in sliding contact with the inner wall of the measuring cylinder.

[0009] A flipping assembly is installed on the inner wall of the cannula;

[0010] Initially, the axis of the tray is perpendicular to the axis of the measuring cylinder, keeping the measuring cylinder open. As the insert moves into the soil, the bottom of the measuring cylinder contacts and is compressed, causing the insert to penetrate the soil and form a sowing hole. Simultaneously, the measuring cylinder slides along the sliding hole into the insert, and the flipping component rotates the tray until its axis is parallel to the axis of the measuring cylinder, closing the measuring cylinder until the feed hole moves into the insert. As the measuring cylinder moves into the insert, its top compresses the corn seeds inside, promoting the seeds to enter the measuring cylinder through the feed hole and fall onto the tray. When the insert is pulled out of the soil, the measuring cylinder slides along the sliding hole outwards, and the flipping component rotates the tray, opening the measuring cylinder and completing the sowing process.

[0011] Preferably, the flipping assembly includes a connecting block, which is fixedly connected to the top of the tray. A connecting shaft is fixedly connected to the inner wall of the connecting block. A first torsion spring is sleeved on the outer circumference of the connecting shaft. The connecting shaft passes through the connecting block and is fixedly connected to it. A fixing block is rotatably connected to the outer circumference of the connecting shaft. A first adjusting gear is fixedly connected to the end of the connecting shaft. A first protrusion is fixedly connected to the outer circumference of the connecting shaft. A first baffle is fixedly connected to the outer wall of the fixing block. One end of the first torsion spring is fixedly connected to the connecting block, and the other end of the first torsion spring is fixedly connected to the fixing block.

[0012] Preferably, a second positioning plate is fixedly connected to the top of the inner wall of the measuring cylinder, and a second adjusting toothed plate is fixedly connected to the outer wall of the second positioning plate.

[0013] Preferably, a fixing rod is fixedly connected to the top of the fixing block, the top of the fixing rod passes through the measuring cylinder and is slidably connected to it, the bottom of the fixing rod is fixedly connected to the fixing block, a support plate is fixedly connected to the inner wall of the insertion tube, the support plate is fixedly connected to the fixing rod, a limit ring is fixedly connected to the outer circumference of the fixing rod, a return spring is sleeved on the outer circumference of the fixing rod, two guide rods pass through and are slidably connected to the support plate, the bottom of the guide rods is fixedly connected to the measuring cylinder, one end of the return spring is fixedly connected to the limit ring, and the other end of the return spring is fixedly connected to the measuring cylinder.

[0014] Preferably, when the measuring cylinder slides into the insertion tube, it simultaneously slides along the fixed rod and compresses the return spring. The second adjusting toothed plate drives the first adjusting gear to rotate until the second adjusting toothed plate separates from the first adjusting gear. At this time, the measuring cylinder is in the closed state. Under the torque of the first torsion spring, the connecting shaft drives the first protrusion to contact the first baffle. The first baffle limits the first protrusion. The measuring cylinder slides out of the insertion tube along the sliding hole. The second adjusting toothed plate pushes the first adjusting gear to rotate in the opposite direction, so that the measuring cylinder is in the open state.

[0015] Preferably, the bottom of the insertion tube is provided with a groove, the sliding hole communicates with the groove, a support ring is fixedly connected to the top of the outer circumference of the measuring cylinder, and a ring plate is fixedly connected to the bottom of the measuring cylinder, the ring plate being slidably connected to the groove.

[0016] Preferably, a rotating shaft is rotatably connected to the inner wall of the feed hole, a material feeding plate is fixedly connected to the outer circumference of the rotating shaft, a second adjusting gear is fixedly connected to the outer circumference of the rotating shaft, a second torsion spring is sleeved on the outer circumference of the rotating shaft, a second protrusion is fixedly connected to the outer circumference of the rotating shaft, a second baffle is fixedly connected to the inner wall of the measuring cylinder, at least one through hole is opened in the inner wall of the support ring, at least one first positioning plate is fixedly connected to the bottom of the support plate, the bottom of the first positioning plate passes through the through hole and extends to below the support ring, a first adjusting toothed plate is fixedly connected to the outer wall of the first positioning plate, one end of the second torsion spring is fixedly connected to the measuring cylinder, and the other end is fixedly connected to the material feeding plate.

[0017] Preferably, when the measuring cylinder slides into the insertion tube, the first adjusting toothed plate pushes the second adjusting gear to rotate, causing the rotating shaft to drive the material-pulling plate to rotate into the measuring cylinder and disengage from the obstruction of the feed hole. When the measuring cylinder slides out of the insertion tube, the first adjusting toothed plate separates from the second adjusting gear, and at the same time, the material-pulling plate flips in the opposite direction to pull out the corn seeds stuck in the feed hole.

[0018] Preferably, the insertion tube is rotatably connected to the fixed plate, and a plurality of crushing rods are fixedly connected to the outer circumference of the insertion tube. The plurality of crushing rods are arranged in a spiral disc. A gear ring is fixedly connected to the outer wall of the insertion tube. A motor is fixedly connected to the top of the fixed plate. The output end of the motor passes through the fixed plate and extends below it. A drive gear is fixedly connected to the output end of the motor. The drive gear meshes with the gear ring. A sealing cover is rotatably connected to the top of the inner wall of the insertion tube. A conveying pipe is fixedly connected to the inner wall of the sealing cover.

[0019] A method for using a corn fertilization device includes the following steps:

[0020] S1. The equipment is in its initial state, with the tray axis of the measuring cylinder perpendicular to the axis of the measuring cylinder, so that the measuring cylinder is in the open state; corn seeds are supplied into the insertion tube through the conveying pipe.

[0021] S2. Drive the insertion tube to rotate and move it toward the soil, using its semi-circular structure at the bottom and the breaking rod to cut into the soil to form a seeding hole; during this process, the fertilizer tube applies fertilizer to the side of the seeding hole.

[0022] S3. During the process of inserting the tube into the soil, the bottom of the measuring cylinder is squeezed by the soil and slides into the tube along the sliding hole. The flipping component drives the tray to flip so that its axis is parallel to the axis of the measuring cylinder, so that the measuring cylinder turns to the closed state. At the same time, the sliding top of the measuring cylinder presses the corn seeds in the tube, causing the seeds to enter the closed measuring cylinder through the feed hole and fall onto the tray, thus completing the seed collection.

[0023] S4. Pull the insertion tube out of the soil. Under the action of the return spring, the measuring cylinder slides out of the insertion tube along the sliding hole. During this process, the feeding plate is flipped in the opposite direction by the linkage between the first adjusting tooth plate and the second adjusting gear, and the seeds stuck in the feeding hole are pulled out.

[0024] S5. As the measuring cylinder slides outward to reset, the flipping component drives the tray to flip back to its initial state, causing the measuring cylinder to open and the seeds inside to fall into the sowing hole, thus completing the sowing.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. In traditional seeders, seeds are easily affected by airflow and soil surface during the sowing process, causing them to bounce and roll. This invention uses a measuring cylinder to directly insert the seeds into the soil, avoiding the seed-throwing process. The seeds are protected inside the measuring cylinder until they fall directly into the sowing hole, eliminating external interference and preventing missed sowing and uneven plant spacing. Traditional seeders require separate hole-opening, sowing, and fertilization devices, resulting in complex equipment, high costs, and easy deviations in coordination. In this invention, the insert, measuring cylinder, and fertilization tube are integrated into one unit. The insert directly enters the soil to form the sowing hole, while the measuring cylinder simultaneously picks up and sows the seeds, and the fertilization tube applies fertilizer at the same time, achieving simultaneous hole opening, sowing, and fertilization. This design reduces equipment components, lowers complexity and manufacturing costs, and ensures consistent distances between the fertilization point, seed hole, and sowing point through mechanical linkage, avoiding fertilization deviations and the risk of seedling burn.

[0027] 2. Compared with the fixed-shape holes on traditional seeding wheels, the seeds in this invention enter the measuring cylinder through the feed hole under the action of extrusion pressure. It has better tolerance for slightly irregularly shaped corn seeds and reduces the risk of seed jamming or missed sowing caused by differences in seed shape.

[0028] 3. During the sowing process, the seeds are supported and transported by the tray inside the measuring cylinder, avoiding direct contact with high-speed rotation or impact. In particular, the rubber ring can make flexible contact with the inner wall of the measuring cylinder when the tray is flipped, further reducing the probability of mechanical damage to the seeds.

[0029] 4. The friction and vibration of the rubber ring can be transmitted to the surface of the vibrating plate, so that the seeds on the vibrating plate are evenly dispersed, avoiding the accumulation of seeds due to moisture or shape differences, and ensuring that the seeds are evenly distributed when falling into the seed hole, thus improving the uniformity of germination.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] like Figures 1-5 As shown, a corn fertilization device includes a fixing plate 1, an insertion tube 2 installed inside the fixing plate 1, a fertilizer tube 6 fixedly connected to the inner wall of the fixing plate 1, the bottom of the insertion tube 2 has a semi-circular structure, and a through sliding hole 202 is opened at the bottom of the inner wall of the insertion tube 2.

[0042] A measuring cylinder 24 is slidably connected to the inner wall of the sliding hole 202, and at least one feed hole 2401 is opened on the outer circumference of the measuring cylinder 24.

[0043] The measuring cylinder 24 is provided with a tray 22, and a rubber ring 23 is fixedly connected to the outer circumference of the tray 22. The outer circumference of the rubber ring 23 is in sliding contact with the inner wall of the measuring cylinder 24.

[0044] A flipping assembly is installed on the inner wall of cannula 2;

[0045] Initially, the axis of tray 22 is perpendicular to the axis of measuring cylinder 24, keeping measuring cylinder 24 in the open state. When the insertion tube 2 moves into the soil, the bottom of measuring cylinder 24 contacts and is squeezed into the soil, causing the insertion tube 2 to be inserted into the soil to form a sowing hole. At the same time, measuring cylinder 24 slides into the insertion tube 2 along the sliding hole 202. The flipping component drives tray 22 to flip until its axis is parallel to the axis of measuring cylinder 24, keeping measuring cylinder 24 in the closed state, until the feed hole 2401 moves into the insertion tube 2. When measuring cylinder 24 moves into the insertion tube 2, its top squeezes the corn seeds in the insertion tube 2, promoting the corn seeds to enter measuring cylinder 24 through feed hole 2401 and fall onto tray 22. When the insertion tube 2 is pulled out of the soil, measuring cylinder 24 slides out of the insertion tube 2 along the sliding hole 202. The flipping component drives tray 22 to flip, keeping measuring cylinder 24 in the open state, completing the sowing.

[0046] By integrating the structure of the insertion tube 2, measuring cylinder 24, and flipping assembly, the hole opening, seed collection, and sowing are integrated into one unit, replacing the traditional separate steps of hole opening, seeding wheel, and fertilization. This reduces the complexity of the equipment and manufacturing costs. When the insertion tube 2 is inserted into the soil, a sowing hole is formed simultaneously, avoiding the impact of airflow and soil protrusion during seed drop, thus solving the problems of missed sowing and uneven plant spacing. Compared with existing equipment, this improves sowing accuracy.

[0047] The measuring cylinder 24 has a fixed volume, which, combined with the seed-taking design of the feed hole 2401, reduces the error in the number of seeds sown each time.

[0048] During sowing, the seeds are supported and transported within the measuring cylinder 24 by the tray 22, avoiding direct contact with high-speed rotation or impact. In particular, the rubber ring 23 allows for flexible contact with the inner wall of the measuring cylinder 24 when the tray 22 is flipped, further reducing the probability of mechanical damage to the seeds.

[0049] Compared to the fixed-shape holes on traditional seeding wheels, in this invention, seeds enter the measuring cylinder 24 through the feed hole 2401 under the action of extrusion pressure. This has better tolerance for slightly irregularly shaped corn seeds and reduces the risk of seed jamming or missed sowing caused by differences in seed shape.

[0050] like Figure 2 , Figure 5 and Figure 6 As shown, the flipping assembly includes a connecting block 19, which is fixedly connected to the top of the tray 22. A connecting shaft 16 is fixedly connected to the inner wall of the connecting block 19. A first torsion spring 17 is sleeved on the outer circumference of the connecting shaft 16. The connecting shaft 16 passes through the connecting block 19 and is fixedly connected to it. A fixing block 15 is rotatably connected to the outer circumference of the connecting shaft 16. A first adjusting gear 18 is fixedly connected to the end of the connecting shaft 16. A first protrusion 20 is fixedly connected to the outer circumference of the connecting shaft 16. A first baffle 21 is fixedly connected to the outer wall of the fixing block 15. One end of the first torsion spring 17 is fixedly connected to the connecting block 19, and the other end of the first torsion spring 17 is fixedly connected to the fixing block 15.

[0051] The meshing transmission between the first adjusting gear 18 and the second adjusting gear plate 31 ensures that the flipping angle of the tray 22 is fixed, avoiding the measuring cylinder 24 from being poorly sealed or unable to be opened due to over- or under-flipping; the first torsion spring 17 can provide the power for reset, and together with the limiting of the first protrusion 20 and the first baffle 21, ensures that the position of the tray 22 is fixed after flipping.

[0052] A second positioning plate 30 is fixedly connected to the top of the inner wall of the measuring cylinder 24, and a second adjusting toothed plate 31 is fixedly connected to the outer wall of the second positioning plate 30.

[0053] The cooperation between the second adjusting toothed plate 31 and the first adjusting gear 18 forms a conversion from linear sliding to rotary transmission, ensuring that the tray 22 flips synchronously when the measuring cylinder 24 moves upward, without the need for additional driving components, thus simplifying the structure.

[0054] A fixing rod 12 is fixedly connected to the top of the fixing block 15. The top of the fixing rod 12 passes through the measuring cylinder 24 and is slidably connected to it. The bottom of the fixing rod 12 is fixedly connected to the fixing block 15. A support plate 10 is fixedly connected to the inner wall of the insertion tube 2. The support plate 10 is fixedly connected to the fixing rod 12. A limit ring 13 is fixedly connected to the outer circumference of the fixing rod 12. A reset spring 14 is sleeved on the outer circumference of the fixing rod 12. Two guide rods 11 pass through and are slidably connected to the support plate 10. The bottom of the guide rod 11 is fixedly connected to the measuring cylinder 24. One end of the reset spring 14 is fixedly connected to the limit ring 13. The other end of the reset spring 14 is fixedly connected to the measuring cylinder 24.

[0055] When the measuring cylinder 24 slides into the insertion tube 2, it also slides along the fixed rod 12 and compresses the return spring 14. The second adjusting tooth plate 31 drives the first adjusting gear 18 to rotate until the second adjusting tooth plate 31 separates from the first adjusting gear 18. At this time, the measuring cylinder 24 is in the closed state. Under the torque of the first torsion spring 17, the connecting shaft 16 drives the first protrusion 20 to contact the first baffle 21. The first baffle 21 limits the first protrusion 20. The measuring cylinder 24 slides out of the insertion tube 2 along the sliding hole 202. The second adjusting tooth plate 31 pushes the first adjusting gear 18 to rotate in the opposite direction, so that the measuring cylinder 24 is in the open state.

[0056] The fixed rod 12 and the guide rod 11 together provide sliding guidance for the measuring cylinder 24, preventing the measuring cylinder 24 from tilting when it moves.

[0057] The seed-dispensing plate 35 first cleans the seeds, and then the tray 22 opens. This prevents uncleaned, sticky seeds from falling into the sowing holes along with the normal seeds, further reducing the risk of over-sowing.

[0058] like Figure 8 As shown, in some embodiments, a vibratory plate 2201 may also be provided on the top of the tray 22. A vibration gap is left between the vibratory plate 2201 and the tray 22. The vibratory plate 2201 is sleeved on the connecting block 19 and is fixedly connected to the connecting block 19 at two points through the connecting rod 2202. The rubber ring 23 is fixed on the outer peripheral wall of the vibratory plate 2201.

[0059] The friction and vibration of the rubber ring 23 can be transmitted to the surface of the vibrating plate 2201, so that the seeds on the vibrating plate 2201 are evenly dispersed, avoiding the accumulation of seeds due to moisture or shape differences, so that the seeds are evenly distributed when falling into the seed hole, and improving the uniformity of seedling emergence.

[0060] like Figures 2-5 As shown, the bottom of the insertion tube 2 is provided with a groove 201, and the sliding hole 202 communicates with the groove 201. The top of the outer circumference of the measuring cylinder 24 is fixedly connected with a support ring 26, and the bottom of the measuring cylinder 24 is fixedly connected with a ring plate 25, which is slidably connected to the groove 201.

[0061] The sliding fit between the ring 25 and the groove 201 reduces the amount of soil particles entering the insertion tube 2 when the measuring cylinder 24 slides, thus preventing seed contamination or component jamming; the support ring 26 limits the top of the measuring cylinder 24 to ensure that seeds can enter the measuring cylinder 24 when taking seeds, thus preventing missed seeds.

[0062] like Figure 5 and Figure 7 As shown, a rotating shaft 32 is rotatably connected to the inner wall of the feed hole 2401. A material-pulling plate 35 is fixedly connected to the outer circumference of the rotating shaft 32. A second adjusting gear 36 is fixedly connected to the outer circumference of the rotating shaft 32. A second torsion spring 34 is sleeved on the outer circumference of the rotating shaft 32. A second protrusion 33 is fixedly connected to the outer circumference of the rotating shaft 32. A second baffle 37 is fixedly connected to the inner wall of the measuring cylinder 24. At least one through hole 27 is opened in the inner wall of the support ring 26. At least one first positioning plate 28 is fixedly connected to the bottom of the support plate 10. The bottom of the first positioning plate 28 passes through the through hole 27 and extends to the bottom of the support ring 26. A first adjusting toothed plate 29 is fixedly connected to the outer wall of the first positioning plate 28. One end of the second torsion spring 34 is fixedly connected to the measuring cylinder 24, and the other end is fixedly connected to the material-pulling plate 35.

[0063] When the measuring cylinder 24 slides into the insertion tube 2, the first adjusting tooth plate 29 pushes the second adjusting gear 36 to rotate, causing the rotating shaft 32 to drive the material-pulling plate 35 to rotate into the measuring cylinder 24, thus disengaging from the obstruction of the feed hole 2401. When the measuring cylinder 24 slides out of the insertion tube 2, the first adjusting tooth plate 29 separates from the second adjusting gear 36, and at the same time, the material-pulling plate 35 flips in the opposite direction to pull out the corn seeds stuck in the feed hole 2401.

[0064] The cooperation between the feed plate 35 and the second adjusting gear 36 removes the obstruction to the feed hole 2401 when picking up seeds, and reverses to clean up stuck seeds after sowing, thus solving the problem of seeds getting stuck and missing in the hole in traditional seeding wheels.

[0065] The fixed connection between the first positioning plate 28 and the first adjusting toothed plate 29 makes the first adjusting toothed plate 29 stationary synchronously with the support plate 10, and forms a relative motion with the second adjusting gear 36 driven by the measuring cylinder 24, thereby realizing the automatic flipping of the feeding plate 35.

[0066] like Figure 1 As shown, the insertion tube 2 is rotatably connected to the fixed plate 1. Multiple crushing rods 3 are fixedly connected to the outer circumference of the insertion tube 2. The multiple crushing rods 3 are arranged in a spiral disc. A gear ring 9 is fixedly connected to the outer wall of the insertion tube 2. A motor 7 is fixedly connected to the top of the fixed plate 1. The output end of the motor 7 passes through the fixed plate 1 and extends to its lower part. A drive gear 8 is fixedly connected to the output end of the motor 7. The drive gear 8 meshes with the gear ring 9. A sealing cover 4 is rotatably connected to the top of the inner wall of the insertion tube 2. A conveying pipe 5 is fixedly connected to the inner wall of the sealing cover 4.

[0067] When the spiral crushing rod 3 rotates, it can reduce the resistance of the insertion tube 2 into the soil and increase the speed of opening the hole; at the same time, the crushing rod 3 mixes the soil, making the soil around the sowing hole loose, which is conducive to seed germination.

[0068] When the multiple spirally arranged breaking rods 3 rotate to open the holes, the insertion tube 2 will form a slight compaction effect on the inner wall of the sowing hole, reducing the amount of soil particles falling back into the hole and avoiding the problem of different seed coverage depths caused by the collapse of the hole shape after traditional hole opening.

[0069] The fertilizer tube 6 extends parallel to the insertion tube 2, and its bottom fertilizer outlet section bends outward and downward towards the insertion tube (2).

[0070] As a key preferred embodiment, the shortest distance between the fertilizer outlet of the fertilizer tube 6 and the outer wall of the insertion tube 2 on the horizontal plane is set to 5 cm. When the insertion tube 2 is inserted into the soil to form a planting hole, the fertilizer discharged from the fertilizer tube 6 will fall into an independent fertilizer hole that is spatially separated from the planting hole. By rigidly connecting the fertilizer tube 6 and the insertion tube 2 to the same fixed plate 1, the distance fluctuation caused by the misalignment of the traditional split-type equipment is eliminated. Whether it is lateral offset or longitudinal depth difference, this device can ensure that the relative position of the planting hole and the fertilizer point remains unchanged in each operation, solve the problem of fertilizer point drift mentioned in the background technology, prevent seedling burn, and improve the fertilization effect.

[0071] Working principle: The fixing plate 1 is installed on the seeder. The fixing plate 1 is driven by the hydraulic cylinder installed on the seeder to move up and down. The fertilizer pipe 6 is pre-connected with fertilizer and connected to the fertilizer mechanism on the seeder.

[0072] Corn seeds are injected into the insertion tube 2 through the feed pipe 5. In the initial state, the axis of the tray 22 of the measuring cylinder 24 is perpendicular to the axis of the measuring cylinder 24, the measuring cylinder 24 is in the open state, and the feed hole 2401 is located below the insertion tube 2.

[0073] The hydraulic cylinder drives the fixed plate 1 to move downwards, and the seeder intermittently moves to the sowing area. The motor 7 is started, and the output end of the motor 7 drives the drive gear 8 to rotate. The drive gear 8 drives the insertion tube 2 to rotate around its own axis through the gear ring 9. The crushing rod 3 on the outer wall of the insertion tube 2 rotates and cuts the weeds and clumps in the soil, making the soil loose. At the same time, the insertion tube 2 is inserted into the loose soil to form a sowing hole. During the insertion of the insertion tube 2 into the soil, the ring plate 25 at the bottom of the measuring cylinder 24 first contacts the soil and is squeezed, causing the measuring cylinder 24 to slide along the sliding hole 202 into the insertion tube 2. On the one hand, the measuring cylinder 24 slides along the fixed rod 12 and compresses the return spring 14. On the other hand, the second adjusting tooth plate 31 on the inner wall of the measuring cylinder 24 meshes with the first adjusting gear 18, driving the connecting shaft 16 to rotate, so that the tray 22 flips so that its axis is parallel to the axis of the measuring cylinder 24. The measuring cylinder 24 switches to the closed state, the first torsion spring 17 stores power, and the first protrusion 20 contacts the first baffle 21 to achieve a limit, ensuring that the second adjusting tooth plate 31 can mesh with the first adjusting gear 18 again.

[0074] During the upward movement of the measuring cylinder 24, its top and the support ring 26 squeeze the corn seeds in the insertion tube 2, causing the corn seeds in the insertion tube 2 to peristalse. At the same time, the first adjusting tooth plate 29 pushes the second adjusting gear 36 to rotate, causing the feeding plate 35 to flip inside the measuring cylinder 24, releasing the obstruction to the feeding hole 2401. The seeds enter the measuring cylinder 24 through the feeding hole 2401 and fall onto the tray 22, completing the quantitative seed collection. At this time, the fixed plate 1 stops moving, the motor 7 runs, and the fertilizer tube 6 delivers fertilizer to the side of the sowing hole when the fixed plate 1 descends to the lowest point, realizing the synchronization of hole opening, seed collection and fertilization.

[0075] After the insertion tube 2 completes the hole opening, the hydraulic cylinder drives the fixing plate 1 to move upward, and the insertion tube 2 is pulled out of the soil; the reset spring 14 releases its elastic force, pushing the measuring cylinder 24 to slide out of the insertion tube 2 along the sliding hole 202, the first adjusting tooth plate 29 separates from the second adjusting gear 36, the second torsion spring 34 drives the material-pulling plate 35 to flip in the opposite direction, and pulls out the seeds stuck in the feed hole 2401, avoiding over-sowing and causing the measuring cylinder 24 to get stuck; at the same time, the second adjusting tooth plate 31 separates from the first adjusting gear 18, the first torsion spring 17 drives the connecting shaft 16 to rotate in the opposite direction, the tray 22 flips to the initial open state, and the seeds in the measuring cylinder 24 fall into the sowing hole; after the measuring cylinder 24 is completely reset, the ring plate 25 returns to the groove 201, and the next working cycle begins.
