Description

Technical Field

[0001] This invention relates to the field of seeder technology, specifically to a seed planter for pasture grass. Background Technology

[0002] Currently, most film-laying seeders can complete multiple complex operations in one go, such as leveling the land, laying the film, seeding on the film, and covering the seed holes with soil. However, in the operation of existing film-laying seeders, when the seeding tube is inserted into the soil layer, the soil can easily block the bottom of the seeding tube, making it difficult for the seeds inside the seeding tube to fall into the soil layer, which may lead to seeding failure. Furthermore, when covering the edges of the film with soil, factors such as wind or uneven film edges may cause the film edges to roll up, affecting the quality of the soil covering. If the wind is strong after covering the film edges with soil, it may even lift the film. Summary of the Invention

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a forage seed hill-seeder. When the hill-seeding tube is inserted into the soil, a soil-dispersing hill-seeding plate seals the bottom of the tube. When the tube reaches its maximum insertion depth, the seed drop control component opens the seed release hole to release the forage seeds. At this time, the soil-dispersing hill-seeding plate also opens the bottom of the tube, creating a space in the soil to accommodate the forage seeds. This prevents the bottom of the tube from being blocked by soil, thus avoiding sowing failure and ensuring that the forage seeds are sown into the soil. Before mulching, furrows are prepared in advance. After mulching, the mulch is not only pressed flat onto the ground by a mulch-laying component, but also pressed into the furrows by a conical edge-pressing wheel, ensuring stable soil covering and fixing of the mulch edges. This improves the quality of soil covering and prevents the mulch from being lifted by excessive wind after mulching, effectively solving the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a forage seed hill-planter, comprising a tractor mounting mechanism, wherein the tractor mounting mechanism includes a mounting longitudinal beam, and further comprising: The multi-functional bracket includes a parallelogram height-following component and a U-shaped frame. Two U-shaped frames are provided on the right side of the mounting longitudinal beam, and the top of each U-shaped frame is connected to the mounting longitudinal beam through two parallelogram height-following components. The hole-seeding mulching auxiliary mechanism is installed on the bottom left side of the U-shaped frame; The film-coating and edge-pressing mechanism is installed on the bottom right side of the U-shaped frame; The forage seed sowing mechanism includes a movable support frame, a rolling sowing component, and a seed drop control component. The right side of the film pressing mechanism is connected to two movable supports. The bottom of each movable support frame is equipped with a rolling sowing component, and the seed drop control component is installed on the rolling sowing component. The soil-adding and film-pressing mechanism is installed on the right side of the film-covering and edge-pressing mechanism.

[0005] The mounting beam is used to install at the rear of the tractor. The parallelogram height-following component allows the U-shaped frame to move up and down relative to the mounting beam, enabling the hill-sowing and mulching auxiliary mechanism, mulching edge pressing mechanism, forage seed hill-sowing mechanism, and soil-adding and mulching mechanism to operate close to the ground. The hill-sowing and mulching auxiliary mechanism performs pre-mulching work, mainly by leveling the ground and pre-drilling trenches at the corresponding film edges to facilitate deep burial of the film edges, improve the quality of soil covering at the film edges, and prevent strong winds from lifting the film. The mulching edge pressing mechanism releases the film, bringing the main body of the film close to the ground, allowing the film edges to extend into the pre-drilled trenches. The tractor lays the seed in the trench and covers the edges of the film with soil to secure it. The movable bracket is used to install the rolling seeding component, which also helps to keep the rolling seeding component close to the ground for seeding. The rolling seeding component rolls on the ground as the tractor moves to the left. During rolling, the seed drop control component allows the forage seeds to be seeded on both sides of the film through the rolling seeding component. The film is laid first and then the seeding is done. During seeding, the rolling seeding component passes through the film and implants the forage seeds into the soil layer. The soil adding and film pressing mechanism adds soil to the middle of the film as the tractor moves. A small pile of soil is pressed on the middle of the film at intervals to prevent the film from bulging and being torn open by strong winds.

[0006] Furthermore, the movable support includes a reinforcing support beam, a support shaft, a movable sleeve, and a seeding bending frame. The reinforcing support beam is fixedly connected to the film-coating and edge-pressing mechanism. The front and rear ends of the support shaft are fixedly connected to the right side of the reinforcing support beam. Two seeding bending frames are provided on the right side of the support shaft. Two movable sleeves are fixedly connected to the top of each seeding bending frame. The movable sleeves are rotatably sleeved on the support shaft.

[0007] Furthermore, the rolling seeding assembly includes side supports, mounting cylinders, a hollow seeding roller, seeding boxes, seeding tubes, an inclined surface, and seed release holes. Two mounting cylinders are rotatably connected to the middle of both sides of the hollow seeding roller, and the two mounting cylinders are fixedly connected to two side supports. The two side supports are fixedly connected to the bottom ends of a seeding bend frame. Seeding boxes are arranged in a circular array on the outer periphery of the hollow seeding roller, and seed release holes are opened in a circular array on the outer periphery of the hollow seeding roller. The seed release holes connect the seeding boxes and the interior of the hollow seeding roller. Each seeding box is connected to a seeding tube on the side away from the hollow seeding roller, and an inclined surface is provided on the end of the seeding tube away from the seeding box.

[0008] Furthermore, the seed falling control assembly includes a control seat, a movable bolt, an adjusting plate, wear-resistant rollers, a seeding shaft, a valve plate, a control swing shaft, and a torsion spring. The control seat is connected to the bottom of the side fixed seat on one side of the hollow seeding roller. The top of the adjusting plate is fixedly connected to the groove at the bottom of the control seat by the movable bolt. Two wear-resistant rollers are rotatably connected to the bottom of the adjusting plate. The adjusting plate is connected to the control seat through a rotation angle adjustment assembly. Seeding shafts are rotatably connected to one side of each seeding box near the hollow seeding roller. The seeding shafts are fixedly connected to one side of the valve plate. The end of the seeding shaft near the adjusting plate passes through the through groove on the side of the seeding box and connects to one end of the control swing shaft. The other end of the control swing shaft is bent. A torsion spring is sleeved on the part of the seeding shaft located in the through groove. One end of the torsion spring is connected to the control swing shaft and the other end is connected to the seeding box.

[0009] Furthermore, the forage seed hole-sowing mechanism also includes a connecting rod and a soil-dispensing hole-sowing plate. Each inclined surface is movably connected to one end of the soil-dispensing hole-sowing plate near the hollow hole-sowing roller. The middle of the side of the soil-dispensing hole-sowing plate near the hole-sowing tube is movably connected to one end of the connecting rod, and the other end of the connecting rod is movably connected to the middle of the corresponding valve plate.

[0010] Furthermore, the seeding and mulching auxiliary mechanism includes a ground light compaction and leveling component and a trenching component. The ground light compaction and leveling component is installed on the bottom left side of the U-shaped frame, and two trenching components are respectively arranged on the front and rear sides of the bottom of the U-shaped frame. The two trenching components are located on the right side of the front and rear ends of the ground light compaction and leveling component. The ground light compaction and leveling component is used to level the ground, preventing uneven ground from affecting subsequent mulching work and preventing uneven ground from easily damaging the membrane. The trenching component digs trenches at the corresponding two edges of the membrane, making it easier to press the membrane edges into the trenches, preventing the membrane edges from lifting, and improving the quality of soil covering the membrane edges.

[0011] Furthermore, the film-coating and edge-pressing mechanism includes support rods, a film-coating release component, a film-coating ground-adhering component, and an edge-covering soil component. Two support rods are fixedly connected to the front and rear sides of the right end of the U-shaped frame, and a film-coating release component is installed between the left sides of the middle of the two support rods. A film-coating ground-adhering component is installed on the bottom right side of the U-shaped frame, and two edge-covering soil components are installed at the front and rear ends of the bottom right side of the U-shaped frame, respectively. The two edge-covering soil components are located to the right of the front and rear ends of the film-coating ground-adhering component.

[0012] Furthermore, the film-covering and edge-pressing mechanism also includes a longitudinal support column, a rotating sleeve, a movable pressing arm, and a conical pressing wheel. The top of the film-covering and ground-attaching component is fixedly connected to the longitudinal support column, and two rotating sleeves are rotatably sleeved at both ends of the longitudinal support column. One end of two movable pressing arms is fixedly connected to the right side of the two rotating sleeves, and two conical pressing wheels are rotatably connected to the other end of the two movable pressing arms. Each conical pressing wheel is located between the end of the film-covering and ground-attaching component and the edge soil-covering component.

[0013] Furthermore, the soil filling and pressing mechanism includes a disassembly support frame, a soil filling and pressing roller, a soil outlet, a roller ground clearance control component, a soil shoveling and loosening disc, and a soil shoveling and buffer support component. Two disassembly support frames are respectively connected to the right side of the two support rods, and a soil filling and pressing roller is rotatably connected between the right ends of the two disassembly support frames. A soil outlet is opened on the middle side of the soil filling and pressing roller. The roller ground clearance control component is installed on the two disassembly support frames, and two soil shoveling and loosening discs are respectively installed on the two disassembly support frames through two soil shoveling and buffer support components. The two soil shoveling and loosening discs correspond to the bottom ends of the soil filling and pressing roller.

[0014] Furthermore, the soil-filling and film-pressing mechanism also includes rolling protrusions and soil-carrying spiral blades. Rolling protrusions are arranged in a circular array on the outer periphery of both ends of the soil-filling and film-pressing roller, and soil-carrying spiral blades are arranged in a circular array on the inner periphery of both ends of the roller. The rolling protrusions increase the friction between the end of the soil-filling and film-pressing roller and the ground, ensuring stable rolling of the roller as it travels, causing a fixed small mound of soil to form evenly distributed in the middle of the film. The soil-carrying spiral blades, as the roller rolls counterclockwise, spirally transport the soil at the end of the roller to the middle of the roller, allowing the soil inside to be smoothly and stably discharged from the outlet.

[0015] Compared with existing technologies, the beneficial effects of this forage seed planter are: 1. The hill-planting seed planter has a hill-planting and mulching auxiliary mechanism for assisting in the mulching process. This mainly involves leveling the ground and pre-drilling trenches at the corresponding edges of the film to facilitate deep burial of the film edges, improve the quality of soil covering the film edges, and prevent strong winds from lifting the film. The mulching and pressing mechanism is used to release the film, bringing the main body of the film close to the ground, allowing the film edges to extend into the pre-drilled trenches, and fixing the film edges with soil.

[0016] 2. This forage seed hill-seeder features a movable support frame for mounting the rolling hill-seeding component, which also facilitates the rolling hill-seeding component to be close to the ground for hill-seeding. The rolling hill-seeding component rolls on the ground as the tractor moves to the left. During rolling, the seed drop control component allows the forage seeds to be hill-seeded on both sides of the film. The film is covered first, followed by hill-seeding. During hill-seeding, the rolling hill-seeding component passes through the film and implants the forage seeds into the soil layer. The soil-adding and film-pressing mechanism adds soil to the middle of the film as the tractor moves, pressing a small pile of soil at intervals in the middle of the film to prevent the film from bulging inside and being torn open by strong winds.

[0017] 3. This forage seed planter features a soil-pulling planting plate that seals the bottom of the planting tube when it is inserted into the soil. When the planting tube reaches its maximum insertion depth, the seed release control component opens the seed release hole to release the forage seeds. At this time, the soil-pulling planting plate also opens the bottom of the planting tube, creating a space in the soil to accommodate the forage seeds. This prevents the bottom of the planting tube from being blocked by soil, thus ensuring that the forage seeds are sown into the soil. Before mulching, furrows are prepared in advance. After mulching, the mulch is not only pressed flat onto the ground using the mulch-adhering component, but also pressed into the furrows using conical edge-pressing wheels. This ensures that the mulch edges are stably covered with soil, improving the quality of the mulch coverage and preventing the mulch from being lifted by excessive wind after mulching.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1 to 11 This embodiment provides a technical solution: a forage seed hole planter, including a tractor mounting mechanism 1. The tractor mounting mechanism 1 includes a mounting longitudinal beam 11, longitudinal beam U-shaped clamps 12, a fixed beam 13, and a trailing arm 14. The middle left side of the mounting longitudinal beam 11 is fixedly connected to the right side of the fixed beam 13 by four longitudinal beam U-shaped clamps 12. The trailing arm 14 is mounted on the top of the fixed beam 13. With the help of the fixed beam 13 and the trailing arm 14, the mounting longitudinal beam 11 can be mounted on the rear bracket of the tractor.

[0021] It is also equipped with a multi-functional support 3, a hole-sowing and mulching auxiliary mechanism 4, a mulching and edge-pressing mechanism 5, a pasture seed hole-sowing mechanism 6, and a soil-adding and mulching mechanism 7.

[0022] The multi-functional bracket 3 includes a parallelogram height-following component and a U-shaped frame 36. Two U-shaped frames 36 are provided on the right side of the mounting beam 11. For clarity, Figure 1 Only one U-shaped frame 36 is shown on the front side of the mounting longitudinal beam 11. The opening of the U-shaped frame 36 faces to the right. The top of each U-shaped frame 36 is connected to the mounting longitudinal beam 11 by two parallelogram height follower components.

[0023] The parallelogram height-following component includes a clamp 31, a clamp 32, a swing rod 33, a swing rod movable seat 34, and a vertical rod 35. Two vertical rods 35 are fixedly connected to the front and rear ends of the upper middle section of each U-shaped frame 36. The top and middle parts of each vertical rod 35 are movably connected to two swing rod movable seats 34 via pin 1. The two swing rod movable seats 34 are fixedly connected to the right ends of two swing rods 33. The left ends of two swing rods 33 are movably connected to the upper and lower ends of a clamp 32 via pin 2. The two swing rods 33 are arranged in parallel, and the right side of the clamp 32 is parallel to the vertical rod 35. The clamp 32 is fixedly connected to the corresponding position of the mounting beam 11 via two clamps 31. The two swing rods 33, the clamp 32, and the vertical rod 35 form a movable parallelogram. The U-shaped frame 36 will descend under gravity, allowing the components at the bottom of the U-shaped frame 36 to contact the ground and begin operation.

[0024] The seeding and mulching auxiliary mechanism 4 is installed on the bottom left side of the U-shaped frame 36.

[0025] The seeding and mulching auxiliary mechanism 4 includes a ground light compaction and leveling component and a trenching component. The ground light compaction and leveling component is installed on the bottom left side of the U-shaped frame 36, and two trenching components are respectively set on the front and rear sides of the bottom of the U-shaped frame 36. The two trenching components are located on the right side of the front and rear ends of the ground light compaction and leveling component. The ground light compaction and leveling component is used to level the ground to avoid uneven ground affecting subsequent mulching work and to prevent uneven ground from easily damaging the membrane. The trenching component digs trenches at the corresponding two edges of the membrane, making it easier to press the membrane edges into the trenches, preventing the membrane edges from lifting, and improving the quality of soil covering the membrane edges.

[0026] The ground light compaction and leveling assembly includes a reinforcing longitudinal beam 41, roller seats 42, and a ground compaction roller 43. Two roller seats 42 are installed at the front and rear ends of the bottom left side of each U-shaped frame 36. A longitudinal ground compaction roller 43 is rotatably connected between the two roller seats 42. The bottom of the ground compaction roller 43 contacts the ground. As the tractor moves, the ground compaction roller 43 flattens the ground. The front and rear ends of the reinforcing longitudinal beam 41 are fixedly connected to the top of the U-shaped frame 36 at the positions corresponding to the two roller seats 42. The reinforcing longitudinal beam 41 reinforces the connection between the U-shaped frame 36 and the roller seats 42, and also improves the strength of the U-shaped frame 36 itself.

[0027] The trenching assembly includes a round base 44, a telescopic rod 45, a horizontal rod 46, and a trenching disc 47. The round base 44 is fixedly connected to the bottom of the U-shaped frame 36 at the position corresponding to the upright 35. The round base 44 is fixedly connected to the top of the telescopic rod 45 by disassembly bolts. After the telescopic rod 45 is extended or retracted, its length can be locked by screws. The bottom of the telescopic rod 45 is fixedly connected to the trenching disc 47 through the horizontal rod 46. The bottom of the trenching disc 47 is inserted into the soil layer. As the tractor moves to the left, a trench is dug on the ground. This trench corresponds to the end of the ground flattening roller 43, which is used to extend the edge of the membrane into the trench for subsequent covering and fixing with soil. The excavated soil moves away from the side of the U-shaped frame 36.

[0028] The film-coating and edge-pressing mechanism 5 is installed on the bottom right side of the U-shaped frame 36.

[0029] The membrane covering and pressing mechanism 5 includes support rods 51, a membrane release component, a membrane grounding component, and an edge soil covering component. Two support rods 51 are fixedly connected to the front and rear sides of the right end of the U-shaped frame 36. The membrane release component is installed between the left sides of the middle of the two support rods 51. The membrane grounding component is installed on the bottom right side of the U-shaped frame 36. Two edge soil covering components are installed at the front and rear ends of the bottom right side of the U-shaped frame 36, respectively, located to the right of the front and rear ends of the membrane grounding component. The support rods 51 are used to install the membrane release component. Simultaneously, two support rods 51 are fixedly connected to the front and rear ends of the reinforcing support beam 61 to secure it. The membrane release component is used to install the membrane roll and release the membrane. The membrane grounding component presses the membrane released by the membrane release component close to the ground. The edge soil covering component covers the membrane edges with soil. Since the membrane edges are within the pre-dug trench, covering the membrane edges with soil provides better fixation.

[0030] Specifically, the film release assembly includes a side seat 52 and a film roll 53. Two side seats 52 are fixedly connected to the middle left side of the two support rods 51 on the U-shaped frame 36, and a film roll 53 is rotatably connected between the two side seats 52. A film roll can be installed on the film roll 53 to provide film. When the film is pulled, the film roll 53 rotates relative to the side seat 52 to release the film from the film roll.

[0031] The film-covered ground assembly includes a base support plate 56, a film pressing seat 57, and a film pressing roller 58. Two base support plates 56 are fixedly connected to the front and rear ends of the bottom right side of the U-shaped frame 36, respectively. Two film pressing seats 57 are fixedly connected to the inner sides of the two base support plates 56, respectively. A longitudinal film pressing roller 58 is rotatably connected between the two film pressing seats 57. After the film is released from the film-covering roll, it passes around the bottom of the film pressing roller 58. The film pressing roller 58 presses the film onto the ground, which is beneficial for subsequent soil covering operations on the film and hole sowing operations by puncturing the film.

[0032] The edge covering component includes a square base 513, an extension rod 514, and a membrane edge covering plate 515. Two square bases 513 are fixedly connected to the top of the two bottom support plates 56, and the left ends of the two extension rods 514 are fixedly connected to the two square bases 513. The right ends of the two extension rods 514 are inclined to the lower right, and the right ends of the two extension rods 514 are fixedly connected to the two membrane edge covering plates 515. The two membrane edge covering plates 515 refill the soil turned up during trenching back into the trench. Since the membrane has been laid at this time, and the membrane edge is in the trench opened by the trenching component, the soil is refilled into the trench to press and fix the membrane edge, thus completing the covering operation of the membrane edge.

[0033] A membrane release limiting assembly is also provided, which includes a limiting seat 54 and a membrane limiting shaft 55. Two limiting seats 54 are fixedly connected to the left side of the two support rods 51 on the U-shaped frame 36, and two membrane limiting shafts 55 are rotatably connected between the two limiting seats 54. The two membrane limiting shafts 55 are arranged vertically and vertically. After the membrane is released from the coating roll, it passes between the two membrane limiting shafts 55, which can limit the membrane and prevent the part of the membrane between the coating roll and the pressing roller 58 from becoming loose or wrinkled due to lack of limiting, thereby improving the flatness of the membrane during use.

[0034] The film covering and pressing mechanism 5 also includes a longitudinal support column 59, a rotating sleeve 510, a movable pressing arm 511, and a conical pressing wheel 512. The top of the film covering and grounding assembly is fixedly connected to the longitudinal support column 59. Two rotating sleeves 510 are rotatably sleeved at both ends of the longitudinal support column 59. One end of two movable pressing arms 511 is fixedly connected to the right side of the two rotating sleeves 510. Two conical pressing wheels 512 are rotatably connected to the other end of the two movable pressing arms 511. Each conical pressing wheel 512 is located between the end of the film covering and grounding assembly and the edge covering and soiling assembly. Because of the height difference between the trench and the membrane body, the edge of the membrane will not be at the bottom of the trench. When covering the edge of the membrane with soil, it may not be possible to stably compact the edge of the membrane, which may easily cause the membrane to be blown away by strong winds. Therefore, a conical edge pressing wheel 512 is set. As the tractor moves to the left, the conical edge pressing wheel 512 presses the edge of the membrane and moves to the left, ensuring that the edge of the membrane is stably located at the bottom of the trench before the soil is fixed. This is conducive to compacting and fixing the soil around the edge of the membrane and improving the quality of membrane covering.

[0035] The forage seed sowing mechanism 6 includes a movable support, a rolling sowing component and a seed drop control component. The right side of the film covering and pressing mechanism 5 is connected to two movable supports. The bottom of each movable support is equipped with a rolling sowing component, and the seed drop control component is installed on the rolling sowing component. The movable support frame includes a reinforcing support beam 61, a support shaft 62, a movable sleeve 63, and a seeding bending frame 64. A longitudinal reinforcing support beam 61 is fixedly connected between the two support rods 51 in the film-coating and edge-pressing mechanism 5. The right side of the reinforcing support beam 61 is fixedly connected to the front and rear ends of the support shaft 62 via two protrusions. Two seeding bending frames 64 are located on the right side of the support shaft 62. Two movable sleeves 63 are fixedly connected to the top of each seeding bending frame 64, and the movable sleeves 63 are rotatably fitted onto the support shaft 62. The seeding bending frame 64 is movably connected to the support shaft 62 via the movable sleeves 63, allowing the seeding bending frame 64 to move around the support shaft 62. Due to the influence of the weight of the seeding bending frame 64 and the rolling seeding assembly, the rolling seeding assembly at the bottom of the seeding bending frame 64 can remain close to the ground, ensuring stable operation of the rolling seeding assembly during leftward movement.

[0036] The rolling seeding assembly includes side bases 65, mounting cylinders 66, disassembly clamps 67, a hollow seeding roller 68, seeding boxes 69, seeding tubes 610, inclined surfaces 611, and seed release holes 622. Two mounting cylinders 66 are rotatably connected to the middle of both sides of the hollow seeding roller 68 via bearings. The two mounting cylinders 66 are fixedly connected to two side bases 65, and the two side bases 65 are fixedly connected to the bottom ends of a seeding bend frame 64. Specifically, the bottom ends of the seeding bend frame 64 are fixedly connected to the two side bases 65 via two disassembly clamps 67. Seeding boxes 69 are arranged in a circular array on the outer periphery of the hollow seeding roller 68. In this embodiment, each hollow seeding roller 68 is equipped with... There are nine seeding boxes 69. The planting density of forage grass can be adjusted according to the number of seeding boxes 69. Seed release holes 622 are arranged in a ring array on the outer periphery of the hollow seeding roller 68. There are also nine seed release holes 622. As needed, some seed release holes 622 can be blocked with sealing plugs, such as blocking six of them. The remaining three are distributed at equal angles on the hollow seeding roller 68, which can increase the planting spacing. The seed release holes 622 connect the seeding boxes 69 and the interior of the hollow seeding roller 68. Each seeding box 69 is connected to a seeding tube 610 on the side away from the hollow seeding roller 68. The end of the seeding tube 610 away from the seeding box 69 is provided with an inclined surface 611. The mounting cylinder 66 is fixed to the bottom of the seeding bending frame 64 via the side fixing seat 65. The hollow seeding roller 68 can rotate freely relative to the two mounting cylinders 66. Forage seeds to be sown can be added to the hollow seeding roller 68 through one mounting cylinder 66. When the tractor moves to the left, the rolling seeding assembly is pulled to the left by the U-shaped frame 36, the reinforcing support beam 61, and the seeding bending frame 64. Due to its own weight, the seeding tube 610 can penetrate the film and insert into the soil layer. The inclined surface 611 further facilitates the insertion of the seeding tube 610 into the soil layer. As the tractor moves to the left... From a frontal view, the hollow seeding roller 68 rotates counterclockwise, and the forage seeds inside the hollow seeding roller 68 fall through the seed release hole 622 into the seeding box 69 located at the bottom of the seed release hole 622. The forage seeds in the seeding box 69 enter the soil layer through the seeding tube 610, which can complete the seeding of forage seeds. During the actual seeding, the seed falling control component needs to control the seed release hole 622 to prevent the forage seeds from being discharged from the bottom of the seeding tube 610 before it pierces the film and is inserted into the soil layer.

[0037] The seed drop control assembly includes a control base 612, a movable bolt 613, an adjusting plate 614, wear-resistant rollers 615, a seeding shaft 618, a valve plate 619, a control swing shaft 620, and a torsion spring 621. The control base 612 is integrally formed and connected to the bottom of a side mounting base 65 on one side of the hollow seeding roller 68. The top of the adjusting plate 614 is fixedly connected to a groove at the bottom of the control base 612 via the movable bolt 613. Two wear-resistant rollers 615 are rotatably connected to the bottom of the adjusting plate 614. The adjusting plate 614 is connected to the control base 612 via a rotation angle adjustment assembly. Each seeding box 69 is located near the hollow seeding roller 618. One side of the 8 is rotatably connected to a seeding shaft 618. The seeding shaft 618 is fixedly connected to one side of the valve plate 619. The end of the seeding shaft 618 near the adjustment plate 614 passes through the through groove on the side of the seeding box 69 and is connected to one end of the control swing shaft 620. The other end of the control swing shaft 620 is bent and parallel to the side of the hollow seeding roller 68. The part of the seeding shaft 618 located in the through groove is fitted with a torsion spring 621. One end of the torsion spring 621 is connected to the control swing shaft 620 and the other end is connected to the seeding box 69. The torque of the torsion spring 621 causes the valve plate 619 to block the corresponding seed release through hole 622.

[0038] The rotation angle adjustment assembly includes a tension spring 616 and an adjustment shim 617. One side of the control seat 612 is fixedly connected to one end of the tension spring 616 by a rivet, and the other end of the tension spring 616 is fixedly connected to one side of the adjustment plate 614 by a rivet. An adjustment shim 617 is provided between the control seat 612 and the adjustment plate 614. The adjustment shim 617 is located behind the tension spring 616. Loosening the movable bolt 613 allows the adjustment plate 614 to move left and right relative to the movable bolt 613. Adjusting the position of the wear-resistant roller 615 at the bottom of the adjustment plate 614, and then... An adjusting shim 617 of appropriate thickness is placed between the control base 612 and the adjusting plate 614. The tension of the tension spring 616 temporarily clamps the adjusting shim 617 between the adjusting plate 614 and the control base 612. At this time, the position of the adjusting plate 614 is relatively stable but not completely fixed. Then, the movable bolt 613 is tightened to help fix the adjusting plate 614. When the seed falling control component works, the adjusting plate 614 will be pressed by the pressure of the seed falling control component, pressing the adjusting shim 617 even tighter. The adjusting plate 614 will not move due to the operation of the seed falling control component. To make the adjusting plate 614 more stable, an adjusting shim 617 can also be set on the other side between the adjusting plate 614 and the control base 612.

[0039] Viewed from the front, the hollow seeding roller 68 rotates counterclockwise. At the same time, each seeding box 69 also rotates counterclockwise around the center of the hollow seeding roller 68. The control pivot 620 on the side of the seeding box 69 located below the hollow seeding roller 68 encounters resistance from the wear-resistant roller 615 at the bottom of the adjusting plate 614 during counterclockwise rotation. The bent portion of the control pivot 620 near the wear-resistant roller 615 acts as a guide, causing the control pivot 620 to rotate counterclockwise around the seeding shaft 618 at a certain angle (within...). Figure 9 From a visual perspective, this means the control pivot 620 rotates clockwise around the seeding shaft 618, typically by 50 to 80 degrees. At this point, the torque of the torsion spring 621 is overcome, increasing its torque. This causes the control pivot 620 to also drive the valve plate 619 to rotate counter-clockwise via the seeding shaft 618. Figure 11 From a certain perspective, the valve plate 619 rotates clockwise, which opens the seed release hole 622. The seed release hole 622 releases the pasture seeds from the hollow seeding roller 68. The pasture seeds fall into the seeding box 69 and are then discharged through the seeding tube 610. Since the seeding tube 610, located below the hollow seeding roller 68, pierces the membrane and inserts into the soil layer, the pasture seeds fall into the soil, completing the seeding operation. This continues until the bent end of the control shaft 620 completely passes the wear-resistant... Since the wear-resistant roller 615 no longer applies pressure to the control swing shaft 620 as the hollow seeding roller 68 moves counterclockwise, the torque of the torsion spring 621 drives the seeding shaft 618, valve plate 619 and control swing shaft 620 to reset, allowing the valve plate 619 to block the corresponding seed release hole 622 again. As the hollow seeding roller 68 rolls to the left on the ground, the next set of seeding boxes 69 and seeding tubes 610 will be directly below the hollow seeding roller 68, and the above seeding control steps will be repeated.

[0040] Loosening the movable bolt 613 allows the adjusting plate 614 to swing left and right relative to the control seat 612, changing the left and right position of the wear-resistant roller 615 at the bottom of the adjusting plate 614. At this time, the timing of the control swing shaft 620 encountering the wear-resistant roller 615 can be adjusted, which can fine-tune the timing of opening the valve plate 619 to release the forage seeds. Then, the angle adjustment component is used to better stabilize the angle between the adjusting plate 614 and the control seat 612. By retightening the movable bolt 613, the relative positions of the adjusting plate 614 and the control seat 612 are locked again, allowing for fine-tuning of the timing of the forage seed release.

[0041] The forage seed hole-sowing mechanism 6 also includes a connecting rod 623 and a soil-dispensing hole-sowing plate 624. Each inclined surface 611 is movably connected to one end of the soil-dispensing hole-sowing plate 624 near the hollow hole-sowing roller 68. The middle of the side of the soil-dispensing hole-sowing plate 624 near the hole-sowing tube 610 is movably connected to one end of the connecting rod 623. The other end of the connecting rod 623 is movably connected to the middle of the corresponding valve plate 619. When the valve plate 619 blocks the corresponding seed release through hole 622, the soil-dispensing hole-sowing plate 624 also blocks the bottom of the corresponding hole-sowing tube 610. When the valve plate 619 opens the corresponding seed release through hole 622, the soil-dispensing hole-sowing plate 624 also opens the bottom of the corresponding hole-sowing tube 610.

[0042] Specifically, the forage seed hole-sowing mechanism 6 also includes a movable seat 1 625 and a movable seat 2 626. The movable seat 1 625 is located in the middle of the side of the soil-dispensing hole-sowing plate 624 near the hole-sowing insertion tube 610. The movable seat 1 625 is movably connected to one end of the connecting rod 623 through a movable column 1. The movable seat 2 626 is located in the middle of the valve plate 619. The movable seat 2 626 is movably connected to the other end of the connecting rod 623 through a movable column 2.

[0043] When the seeding tube 610 is inserted into the soil, soil may enter the bottom of the tube, potentially clogging it and interfering with the smooth falling of forage seeds into the soil. Therefore, a connecting rod 623 and a soil-dispensing seeding plate 624 are installed. The connecting rod 623 links the soil-dispensing seeding plate 624 and the valve plate 619. Before the seeding tube 610 is inserted downwards into the soil, the valve plate 619 blocks the seed release hole 622. At this time, the soil-dispensing seeding plate 624 also blocks the bottom of the seeding tube 610. The soil-dispensing seeding plate 624 is flush against the inclined surface 611, preventing the bottom of the seeding tube 610 from piercing the laid film or hindering its insertion into the soil. When controlled by the seed falling control component, the valve plate 619 opens. After the seed release hole 622 is opened, the valve plate 619 will also push the soil-dispersing hole-sowing plate 624 through the connecting rod 623. The soil-dispersing hole-sowing plate 624 will dissipate the soil near the slope 611 at the bottom of the hole-sowing tube 610, and at the same time open the bottom of the hole-sowing tube 610. The forage seeds fall into the hole-sowing box 69, and then are discharged through the hole-sowing tube 610 and fall into the space opened by the soil-dispersing hole-sowing plate 624 in the soil layer. As the hollow hole-sowing roller 68 rolls to the left, the hole-sowing tube 610 leaves the planting area. The valve plate 619 will block the corresponding seed release hole 622, and the soil-dispersing hole-sowing plate 624 will also block the bottom of the corresponding hole-sowing tube 610. The soil on the upper layer of the forage seed planting area will cover the hole-sowing position due to gravity, and cover the forage seeds.

[0044] The forage seed sowing mechanism 6 also includes a forage seed adding box 627 and a lid 628. The mounting cylinder 66 in the middle of one side of the hollow sowing roller 68 is connected to the bottom of the forage seed adding box 627. The lid 628 is installed on the top of the forage seed adding box 627. When the lid 628 is opened, forage seeds are put into the forage seed adding box 627. The forage seeds will enter the hollow sowing roller 68 through the mounting cylinder 66, thus completing the forage seed adding work.

[0045] The soil-adding and film-pressing mechanism 7 is installed on the right side of the film-covering and edge-pressing mechanism 5.

[0046] In use, the mounting beam 11 is installed at the rear of the tractor. The parallelogram height-following component allows the U-shaped frame 36 to move up and down relative to the mounting beam 11, thus allowing the hill-sowing and mulching auxiliary mechanism 4, the mulching edge pressing mechanism 5, the pasture seed hill-sowing mechanism 6, and the soil-adding and mulching mechanism 7 to work close to the ground. The hill-sowing and mulching auxiliary mechanism 4 is used to perform auxiliary work before mulching, mainly to level the ground and dig trenches at the corresponding film edges in advance, so as to bury the film edges deeply, improve the soil covering quality of the film edges, and prevent strong winds from lifting the film. The mulching edge pressing mechanism 5 is used to release the film, bringing the main body of the film close to the ground, allowing the film to... The edge extends into the pre-dug trench, and the edge of the film is covered with soil to fix it. The movable bracket is used to install the rolling seeding component, which also facilitates the rolling seeding component to be close to the ground for seeding. The rolling seeding component rolls on the ground as the tractor moves to the left. During rolling, the seed drop control component can make the forage seeds be seeded on both sides of the film through the rolling seeding component. The film is covered first and then seeded. During seeding, the rolling seeding component passes through the film and implants the forage seeds into the soil layer. The soil adding and film pressing mechanism 7 adds soil to the middle of the film as the tractor moves. A small pile of soil is pressed on the middle of the film at intervals to prevent the inside of the film from bulging and to prevent it from being torn open by strong winds.

[0047] Example 2, please refer to Figures 1 to 11 This embodiment provides a technical solution: a pasture seed hill-planter. This embodiment is a further explanation of the structure of Embodiment 1. The soil filling and pressing mechanism 7 includes a disassembly support frame, a soil filling and pressing roller 711, a soil outlet 713, a roller ground lifting control component, a soil shoveling and loosening disc 727, and a soil shoveling and buffer support component. Two disassembly support frames are connected to the right sides of the two support rods 51 respectively. The soil filling and pressing roller 711 is rotatably connected between the right ends of the two disassembly support frames. The two ends of the soil filling and pressing roller 711 are open. A soil outlet 713 is opened on the middle side of the soil filling and pressing roller 711. The roller ground lifting control component is installed on the two disassembly support frames. Two soil shoveling and loosening discs 727 are installed on the two disassembly support frames through two soil shoveling and buffer support components respectively. The two soil shoveling and loosening discs 727 correspond to the bottom ends of the soil filling and pressing roller 711 respectively.

[0048] Specifically, the disassembly support frame includes a hollow extension rod 71, a reinforcing rod 72, a fastening bolt 73, an extension rod 74, a short rod 75, a connecting beam 76, a bending rod 77, a roller frame 78, a roller shaft 79, and spokes 710. Two support rods 51 on the U-shaped frame 36 are horizontally inserted and fixedly connected to two horizontally extending hollow rods 71. The left ends of the two extending hollow rods 71 ​​are fixedly connected to two corresponding uprights 35. The bottoms of the two extending hollow rods 71 ​​are fixedly connected to the top of the right ends of the U-shaped frame 36 via two reinforcing rods 72. The right ends of the two extending hollow rods 71 ​​are horizontally slidably connected to the left ends of two extension rods 74. The top right ends of the two extending hollow rods 71 ​​are threadedly connected to fastening bolts 73, with the bottom ends of the fastening bolts 73 abutting against the extension rods. On the upper side of rod 74, the extended hollow rod 71 and the extension rod 74 are locked. Loosening the fastening bolt 73 allows the extension rod 74 to be adjusted left and right relative to the extended hollow rod 71. Two short rods 75 are fixedly connected to the top right end of the two extension rods 74 respectively. A connecting beam 76 is fixedly connected between the top of the two short rods 75. Two rod seats are respectively provided at the front and rear ends of the top of the connecting beam 76. The two rod seats are movably connected to the left end of two bent rods 77 through rod seat shafts. The bottom of the bend of the two bent rods 77 is fixedly connected to the top of two roller frames 78 respectively. The bottom of the two roller frames 78 is rotatably connected to two roller shafts 79 respectively. Each roller shaft 79 is fixedly connected to the inner end of the soil-filling and pressing roller 711 through three spokes 710 distributed in a ring array.

[0049] The roller ground-lift control assembly includes a control beam 715, a control ring 716, a central rod 717, a movable column 718, and a control pin 719. The right ends of two bent rods 77 are fixedly connected to the front and rear ends of the control beam 715, respectively. A control ring 716 is located in the middle of the control beam 715. The bottom end of the central rod 717 is fixedly connected to the upper side of the middle section of the connecting beam 76. The top end of the central rod 717 is movably connected to one end of the movable column 718 via a rod shaft. The other end of the movable column 718 passes through the control ring 716. The movable column 718 has pin holes spaced evenly at one end near the control beam 715. Control pins 719 are inserted into the pin holes on both sides of the control ring 716. The control pins 719 can be removed to allow the control beam 715, the soil filling and pressing roller 711, and the bending rod 77 to move relative to the rod seat shaft, so that the soil filling and pressing roller 711 is moved away from or closer to the ground, and the height of the soil filling and pressing roller 711 can be adjusted. Then the control pins 719 are reinserted. With the help of the movable column 718, the control ring 716, and the control pins 719, the height position of the soil filling and pressing roller 711 is locked. When the soil filling and pressing roller 711 is not needed, it can be moved away from the ground and locked.

[0050] The soil-moving buffer support assembly includes a sliding rod 720, angle steel 721, sliding guide post 722, wing nut 723, movable seat three 724, soil-loosening movable arm 725, movable seat four 726, retaining sleeve 728, and compression spring 729. Two sliding rods 720 are laterally slidably connected to the inner right ends of two extension rods 74. The sliding rods 720 are fixedly connected to their corresponding extension rods 74 using locking screws. The top right ends of the two sliding rods 720 are fixedly connected to the left sides of two angle steels 721 via two supporting short rods. At the ends, two sliding guide posts 722 are respectively inserted into the through holes at the right ends of the two angle steels 721. The diameter of the through holes is larger than the diameter of the sliding guide posts 722, allowing the sliding guide posts 722 to tilt relative to the angle steels 721. The right end of each sliding rod 720 is movably connected to a movable seat 724 via a movable pin. Each movable seat 724 is fixedly connected to the left end of the loosening arm 725. The right end of the loosening arm 725 is fixedly connected to the soil loosening disc 727. The upper middle part of the loosening arm 725 is fixedly connected to... There is a movable seat 726, which is movably connected to the bottom end of the corresponding sliding guide post 722 via a movable pin 2. Two retaining sleeves 728 are fitted onto the portion of the sliding guide post 722 between the angle steel 721 and the movable seat 726. A compression spring 729 is fitted onto the portion of the sliding guide post 722 between the two retaining sleeves 728. A wing nut 723 is threaded onto the top of the sliding guide post 722. A conical washer is fitted onto the portion of the sliding guide post 722 between the wing nut 723 and the angle steel 721. The elastic force of the compression spring 729 provides a certain buffering force between the soil shovel and loosening disc 727 and the ground. As the terrain undulates, the soil shovel and loosening disc 727 moves up and down, and the right end of the loosening arm 725 also swings up and down. At this time, the sliding guide post 722 will slide up and down relative to the angle steel 721. The compression spring 729 will buffer the up and down movement of the soil shovel and loosening disc 727. By turning the wing nut 723, the compression force of the compression spring 729 can be adjusted in advance, which can change the buffering force on the up and down movement of the soil shovel and loosening disc 727.

[0051] The support frame is removed to install the soil-filling and film-pressing roller 711 and the roller ground-lift control assembly. When not in use, the roller ground-lift control assembly can lift the soil-filling and film-pressing roller 711 away from the ground. When in use, the soil-filling and film-pressing roller 711 is brought into contact with the ground. As the tractor moves to the left, the soil-filling and film-pressing roller 711 rolls counterclockwise on the ground. The soil-shoveling buffer support assembly causes the soil-shoveling and loosening disc 727 to make buffer contact with the ground. As the tractor moves to the left, the soil-shoveling and loosening disc 727 scoops up the soil located on both sides of the film and feeds it into the soil-filling area. Inside the pressing roller 711, when the pressing roller 711 rotates once, some of the soil inside will be discharged through the soil outlet 713, forming a fixed small mound of soil at equal intervals in the middle of the film, fixing the film at equal intervals, and preventing the film from expanding and bulging excessively and being easily blown away by strong winds. Since each reinforcing support beam 61 is equipped with two hole-sowing bending frames 64 and two rolling hole-sowing components on the right side, two rows of pasture seeds will be planted on both sides of each film. Adding small mounds of soil in the middle of the film will not interfere with the growth of the two rows of pasture planted on both sides of the film.

[0052] The soil filling and film pressing mechanism 7 also includes rolling protrusions 712 and soil conveying spiral blades 714. Rolling protrusions 712 are arranged in a circular array on the outer periphery of both ends of the soil filling and film pressing roller 711, and soil conveying spiral blades 714 are arranged in a circular array on the inner periphery of both ends of the soil filling and film pressing roller 711. The rolling protrusions 712 increase the friction between the end of the soil filling and film pressing roller 711 and the ground, ensuring stable rolling of the soil filling and film pressing roller 711 as it travels, causing a fixed small mound of soil to form evenly distributed in the middle of the film. The soil conveying spiral blades 714, as the soil filling and film pressing roller 711 rolls counterclockwise, spirally transport the soil at the end of the soil filling and film pressing roller 711 to the middle of the inner part of the soil filling and film pressing roller 711, allowing the soil inside the soil filling and film pressing roller 711 to be smoothly and stably discharged from the soil outlet 713.

[0053] Example 3, please refer to Figure 1 and Figure 7 This embodiment provides a technical solution: a pasture seed hole planter. This embodiment is structurally similar to Embodiment 2, with the difference being: It is also equipped with a travel support mechanism 2, which includes a support wheel stable ground contact component and a power transmission component.

[0054] The support wheel stable ground contact assembly includes a beam end U-shaped clamp 21, a fixed seat 22, a bent arm 23, a movable cylinder 24, a support swing arm 25, a wheel axle 26, a traveling support wheel 27, a support 213, a buffer slide 214, an end shaft 215, an anti-detachment pin 216, a support buffer spring 217, and a movable shaft 218. Fixed seats 22 are respectively provided on the left side of the front and rear ends of the mounting longitudinal beam 11. Each fixed seat 22 is fixedly connected to the corresponding end of the mounting longitudinal beam 11 by two beam end U-shaped clamps 21. Two bent arms 23 are fixedly connected to the left side of each fixed seat 22. A longitudinal movable cylinder 24 is rotatably connected between the two bent arms 23. The bottom of the movable cylinder 24 is fixedly connected to the top of the support swing arm 25. A longitudinal wheel axle 26 is rotatably connected to the bottom of the support swing arm 25. A traveling support wheel 27 is fixedly connected to the wheel axle 26. In the middle of 7, a support 213 is fixedly connected to the bottom left side of the support arm 25. The support 213 is movably connected to the bottom end of the buffer slide column 214 through the movable shaft 218. A longitudinal end shaft 215 is rotatably connected between the left ends of the two bent arms 23. The sliding hole on the end shaft 215 is slidably connected to the buffer slide column 214. The column section of the buffer slide column 214 located between the support 213 and the end shaft 215 is fitted with a support buffer spring 217. An anti-detachment pin 216 is provided at the top of the buffer slide column 214 to prevent the top of the buffer slide column 214 from detaching from the end shaft 215. The buffer slide column 214, the bent arm 23 and the support arm 25 form a movable triangle. The compression force of the support buffer spring 217 makes the traveling support wheel 27 at the bottom of the support arm 25 stick to the ground, so that the traveling support wheel 27 has sufficient friction with the ground.

[0055] The power transmission assembly includes a driven sprocket 28, a chain 29, a drive shaft 210, a drive sprocket 211, and a drive sprocket 212. The driven sprocket 28 is fixedly connected to the axle 26. The side of the curved arm 23 is rotatably connected to one end of the drive shaft 210 via a bearing. The drive sprocket 211 is fixedly connected to the drive shaft 210. The drive sprocket 211 is connected to the driven sprocket 28 via the chain 29. The drive sprocket 212 is installed at the end of the drive shaft 210. The drive sprocket 212 can be connected to the sprocket on an external power motor via an additional chain. The axis of the drive shaft 210 is aligned with the center of the movable cylinder 24. Even if the movable cylinder 24 and the support swing arm 25 move, it will not affect the power transmission of the driven sprocket 28, chain 29 and drive sprocket 211. The drive sprocket 212 and the drive shaft 210 are powered by an external power motor. The drive shaft 210 can provide power for the rotation of the wheel axle 26 and the traveling support wheel 27 through the transmission of the driven sprocket 28, chain 29 and drive sprocket 211. Since the traveling support wheel 27 has sufficient friction with the ground, it can be used to assist in driving the seeder. An additional drive path can be added by the power transmission components and the external power motor.

[0056] In other embodiments, please refer to Figure 5 It is also equipped with a drip irrigation tape release mechanism 8, which includes a long shaft 81 and a drip irrigation tape roll 82. The long shaft 81 is rotatably connected between the tops of the two support rods 51. The drip irrigation tape roll 82 is set in the middle of the long shaft 81. The drip irrigation tape is wound on the drip irrigation tape roll 82. When covering the film, the drip irrigation tape can be laid on the lower middle part of the film. The drip irrigation tape can be used to drip irrigate the two rows of pasture under the film.
