Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seeding, in particular to an ice grass seeding device capable of adjusting seeding depth. BACKGROUND

[0002] With the progress of science and technology, agricultural production gradually develops from traditional manual labor to mechanization and automation. As an important part of agricultural mechanization, seeding machines are constantly innovated and improved in technology, providing a technical basis and reference for the research and development of ice grass seeding machines. For example, the precision seeding technology and automatic control technology commonly used in modern seeding machines can be applied to ice grass seeding machines to improve the precision and efficiency of ice grass seeding.

[0003] Because the seed size, germination characteristics and root growth habits of different crops are different, there are specific requirements for the plowing depth. The existing seeding machine cannot automatically adjust the seeding depth, and needs to be disassembled manually for adjustment. This structure and mode of adjustment are troublesome, not only consuming labor and time, but also making the structure unstable after disassembly and assembly several times. SUMMARY

[0004] To achieve the above purpose, the present application is realized by the following technical scheme: an ice grass seeding device capable of adjusting seeding depth, comprising a body, a connecting block fixedly connected to the rear end of the body;

[0005] An adjusting assembly is fixedly connected to the end of the connecting block away from the body, and the end of the adjusting assembly away from the connecting block is fixedly connected with a shell;

[0006] A discharging assembly is fixedly installed at the top of the adjusting assembly, near the end of the shell;

[0007] A flattening assembly is fixedly connected to the end of the shell away from the discharging assembly.

[0008] The adjustment component includes a fixed block, which is fixedly connected to a connecting block. A support block is fixedly connected to the top of the fixed block, and a hydraulic cylinder is fixedly connected inside the support block. An annular groove is formed on the outer side of the fixed block, and a fixed rod is slidably connected to the inner wall of the annular groove. The output end of the hydraulic cylinder is fixedly connected to the fixed rod, and a slotted assembly is fixedly connected to the outer shell of the fixed rod. During use, the main body moves, allowing the equipment to travel on both sides of the soil ridge. At this time, the seeder is used for sowing on the soil ridge. Since different crops have different seed sizes, germination characteristics, and root growth habits, there are specific requirements for the tillage depth. The hydraulic cylinder adjusts the fixed rod to slide up and down inside the annular groove, causing the round rod on the fixed rod to move downward inside the round hole. Thus, the round rod drives the pointed shovel to move through the connecting rod. This allows for adjustment of the sowing depth. By adjusting the sowing depth appropriately, the crop roots can be distributed more evenly and rationally in the soil, making full use of the nutrients and water in different soil layers. At the same time, a reasonable sowing depth helps to disrupt the living environment of pests and diseases, reducing their occurrence. The fixed block has a circular groove on the side near the feeding component. The support block has an L-shaped design, with two support blocks symmetrically arranged at both ends of the fixed block. The annular groove runs through the fixed block. The top of the fixed block has multiple circular holes evenly distributed. The circular rod is located inside the circular holes. The annular groove is set perpendicular to the circular holes. A trapezoidal block is fixedly connected to the bottom of the fixed block away from the connecting block. The trapezoidal block has a sliding groove on the side near the fixed block.

[0009] Preferably, the grooving assembly includes a round rod, which is fixedly connected to a fixed rod. A connecting rod is provided at the bottom of the round rod, and a pointed shovel is fixedly connected to the end of the connecting rod away from the round rod. The pointed shovel has a triangular design. During the operation of the seeder, the triangular pointed shovel is brought into the soil as the seeder moves forward. Due to its sharp tip, it can easily cut into the soil. Even when encountering hard clods of soil or crop residues, it can break or push them apart due to its sturdy structure and the wedging effect of the triangle, creating favorable conditions for subsequent sowing and fertilization. Furthermore, as the triangular pointed shovel moves forward in the soil, it compresses the soil to both sides, forming a trench with the required width and depth. The rod is rotatably connected, and a guide plate is fixedly connected to the outer side of the connecting rod near the pointed shovel. When the triangular pointed shovel cuts into the soil, the inclined guide plate allows the soil to flow to both sides at a certain angle along its surface. Due to soil loosening and machine vibration, some soil may flow back into the already dug trench. At this time, the guide plate can also act as a barrier to reduce soil backflow, keeping the trench's outline clear, which is beneficial for subsequent sowing and covering operations. There are two guide plates, symmetrically arranged around the connecting rod. A connecting rod is fixedly connected to the outer side of the connecting rod near the round rod. The end of the connecting rod away from the connecting rod is rotatably connected to a middle rod. A slider is fixedly connected to one end of the connecting rod. The slider is located inside the chute, and the slider and chute are slidably connected. A compression spring is fixedly connected to the side of the slider near the middle rod. During the use of the equipment, the pointed shovel will continuously come into contact with the soil and be impacted. The compression spring can buffer and dampen the impact force transmitted from the pointed shovel to other parts of the seeder, thereby reducing the wear and tear on various parts and extending the service life of the seeder. At the same time, when the pointed shovel encounters hard objects such as stones or tree roots, the compression spring is compressed, causing the connecting rod and connecting rod to rotate. At this time, the connecting rod drives the pointed shovel to fold, avoiding hard collisions with hard objects that could damage the pointed shovel. This effectively protects the pointed shovel and related components of the seeder, reducing maintenance costs and downtime. The round rod drives the connecting rod and slider to move downwards, and the pointed shovel moves downwards. As the depth of the pointed shovel into the soil increases, the volume and area of ​​soil in contact with the pointed shovel also increase accordingly. The friction and normal pressure of the soil on the pointed shovel will increase with the increase of depth. At the same time, the slider slides on the trapezoidal block, causing the compression spring to compress. At this time, the elastic force of the folding is adjusted, and the pressure value of the folding rotation is adjusted according to the tillage depth. The end of the compression spring away from the slider is fixedly connected to the connecting rod. The top of the middle rod is fixedly connected to the middle plate, and one end of the middle plate is fixedly connected to the end of the round rod near the connecting rod.

[0010] Preferably, the flattening component includes gears located at the end of the housing away from the adjusting component. A rotating shaft is fixedly connected to the outer side of the gears. There are multiple gears, symmetrically arranged around the rotating shaft. A circular plate is fixedly connected to the outer side of the rotating shaft. There are multiple circular plates, and a limiting rod is fixedly connected to the outer side of the circular plates. The main body drives the housing to move through connecting blocks and fixing blocks, causing the housing to drive the circular plates to rotate. During the rolling process, the circular plates compact the soil surface with their own weight, which can compact and flatten the relatively loose and uneven soil surface after tilling, providing a relatively flat bed surface for subsequent sowing, which is conducive to uniform sowing and covering of seeds and improves sowing quality. There are multiple limiting rods, evenly distributed on the circular plates around the rotating shaft. A limiting component is fixedly connected to the outer side of the rotating shaft. There are multiple limiting components, and multiple circular plates and limiting components are alternately arranged. A cleaning component is provided on the outer side of the circular plates, and the two ends of the cleaning component are fixedly connected to the two ends of the rotating shaft.

[0011] Preferably, the limiting component includes a positioning plate, which is fixedly connected to the rotating shaft. The positioning plate is located at the interval between two adjacent circular plates. A square hole is opened on the outer side of the positioning plate. When the circular plates rotate, the edge limiting rod will also rotate. During its rotation, the soil can be further turned over and stirred. At the same time, the rotating shaft drives the pressure plate to rotate, so that it comes into direct contact with the soil. Using its own weight and the elastic force of the return spring, the soil becomes more compact. By combining the action of the limiting rod, the pressure plate and the return spring, the soil can be mixed more evenly, the soil structure can be improved, the soil aeration and permeability can be increased, and better soil conditions can be created for plant growth. This provides a good soil foundation for subsequent sowing or other agricultural operations. There are multiple square holes, which are evenly distributed around the rotating shaft. A return spring is fixedly connected to the inner wall of the square hole. The end of the return spring away from the square hole is fixedly connected to the pressure plate, and the pressure plate is slidably connected to the square hole.

[0012] Preferably, the cleaning component includes a ring, which is fixedly connected to a rotating shaft. A limiting block is fixedly connected to the outer side of the ring, and a protective shell is fixedly connected to the top of the limiting block. A slot is formed on the inner wall of the protective shell, and a locking block is provided on the inner wall of the slot. The locking block is L-shaped and elastic. There are two locking blocks, which are symmetrically arranged. The protective shell engages with the scraper through the cooperation between the slot and the locking block. As the circular plate and the positioning plate rotate with the rotating shaft, the scraper and the cleaning brush clean the outer side of the circular plate and the positioning plate to prevent soil from accumulating on the circular plate and to ensure that the surface of the circular plate is clean, so that it can continuously and effectively compact and turn the soil. A scraper is fixedly connected to the end of the locking block away from the slot, and the scraper contacts the outer side of the circular plate. A cleaning brush is fixedly connected to the side of the scraper closer to the positioning plate.

[0013] Preferably, the feeding assembly includes a housing, which is fixedly connected to the top of a fixed block. A motor is fixedly connected to the outer side of the housing, and a rotating rod is rotatably connected to the inner wall of the housing. The output end of the motor passes through the housing and is fixedly connected to the rotating rod. A spiral plate is fixedly connected to the outer side of the rotating rod. The rotating plate is located inside a circular frame and a circular groove, forming a circle. Seeds are placed inside the housing. The motor, powered by an external power source, drives the rotating shaft to rotate, which in turn drives the spiral plate to rotate, causing the seeds to be evenly distributed on the bottom inner side of the housing. Subsequently, the seeds fall through a through-hole at the bottom into the groove on the rotating plate. The rotating plate, driven by the rotation of a transmission wheel, causes the seeds to leave the housing. Simultaneously, the circular frame restricts any excess seeds in the groove, allowing a fixed quantity of seeds to move to the top of the circular tube. The seeds are discharged from the circular tube under the influence of gravity and then sown. By sowing a fixed amount of seeds, the problem of overly dense or sparse seedlings caused by too much or too little sowing is avoided, providing a good population structure for crop growth and helping to improve crop yield and quality. A circular frame is fixedly connected to the bottom of the outer shell. A transmission wheel is set inside the circular frame. A rotating shaft is fixedly connected to the outer side of the transmission wheel. The transmission wheel is symmetrically arranged around the rotating shaft. The transmission wheel and the gear are connected by a transmission belt. A rotating plate is fixedly connected to the outer side of the rotating shaft. The outer side of the rotating plate has a slot. There are multiple rotating plates, which are evenly distributed on the rotating shaft. A circular tube is fixedly connected to the bottom of the circular frame and communicates with the circular frame. A through hole is opened at the bottom of the outer shell, and the through hole and the rotating plate are located on the same vertical plane.

[0014] This invention provides an ice grass seeding device with adjustable seeding depth. It has the following beneficial effects:

[0015] I. This adjustable seeding depth ice grass seeding device can make the crop roots more evenly and rationally distributed in the soil by adjusting the planting depth, making full use of the nutrients and water in different soil layers. At the same time, the reasonable planting depth helps to destroy the living environment of pests and diseases and reduce the occurrence of pests and diseases.

[0016] Second, this ice grass sowing device with adjustable sowing depth features a triangular shovel design. When the seeder is in operation, the triangular shovel is brought into the soil as the seeder moves forward. Due to its sharp tip, it can easily cut into the soil. Even if it encounters hard clods of soil or crop residues, it can break or push them away with its sturdy structure and the wedge-like action of the triangle, creating favorable conditions for subsequent sowing and fertilization.

[0017] Third, this ice grass sowing device with adjustable sowing depth allows the soil to flow to both sides at a certain angle along its surface through the inclined guide plate. Due to the loosening of the soil and the vibration of the machine, some soil may flow back into the trenches that have been dug. At this time, the guide plate can also play a blocking role, reducing the phenomenon of soil backflow, keeping the trenches with a clear outline, which is beneficial to subsequent sowing and covering operations.

[0018] IV. The ice grass sowing device with adjustable sowing depth moves downward by the pointed shovel. As the depth of the pointed shovel into the soil increases, the volume and area of ​​the soil in contact with the pointed shovel also increase accordingly. The friction and normal pressure of the soil on the pointed shovel will increase with the increase of depth. At the same time, the slider slides on the trapezoidal block, which compresses the compression spring. At this time, the elastic force of the folding is adjusted, and the pressure value of the folding rotation is adjusted according to the sowing depth. Attached Figure Description

[0030] 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.

[0031] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: an ice grass sowing device with adjustable sowing depth, including a body 1, and a connecting block 2 fixedly connected to the rear end of the body 1;

[0032] Adjustment component 6 is fixedly connected to the end of the connecting block 2 away from the main body 1, and the end of the adjustment component 6 away from the connecting block 2 is fixedly connected to the housing 3;

[0033] The feeding component 4 is fixedly installed on the top of the adjusting component 6 near one end of the housing 3;

[0034] Flattening component 5 is fixedly connected to the end of housing 3 away from feeding component 4.

[0035] The adjusting component 6 includes a fixed block 61, which is fixedly connected to the connecting block 2. A support block 64 is fixedly connected to the top of the fixed block 61, and a hydraulic cylinder 63 is fixedly connected inside the support block 64. An annular groove 66 is formed on the outer side of the fixed block 61, and a fixed rod 67 is slidably connected to the inner wall of the annular groove 66. The output end of the hydraulic cylinder 63 is fixedly connected to the fixed rod 67, and a slotting component 69 is fixedly connected to the outer shell of the fixed rod 67. During use, the main body 1 moves, allowing the equipment to travel on both sides of the soil ridge. At this time, the seeder is used for sowing on the soil ridge. Since the seed size, germination characteristics, and root growth habits of different crops vary, there are specific requirements for the tillage depth. The hydraulic cylinder 63 works to move the fixed rod 67 up and down inside the annular groove 66, causing the round rod 691 on the fixed rod 67 to move downward inside the round hole 610. Thus, the round rod 691 drives the pointed shovel 693 through the connecting rod 692. The planting depth can be adjusted by moving the plant to allow the crop roots to be distributed more evenly and rationally in the soil, making full use of the nutrients and water in different soil layers. At the same time, a reasonable planting depth helps to destroy the living environment of pests and diseases and reduce their occurrence. The fixed block 61 has a circular groove 62 on the side near the feeding component 4. The support block 64 is designed in an L shape and there are two support blocks 64. The two support blocks 64 are symmetrically arranged at both ends of the fixed block 61. The annular groove 66 passes through the fixed block 61. The top of the fixed block 61 has a circular hole 610. There are multiple circular holes 610 evenly distributed. The circular rod 691 is located inside the circular hole 610. The annular groove 66 is set perpendicular to the circular hole 610. The bottom of the fixed block 61 away from the connecting block 2 is fixedly connected to a trapezoidal block 65. The trapezoidal block 65 has a sliding groove 68 on the side near the fixed block 61.

[0036] The grooving assembly 69 includes a round rod 691, which is fixedly connected to a fixed rod 67. A connecting rod 692 is provided at the bottom of the round rod 691. A pointed shovel 693 is fixedly connected to the end of the connecting rod 692 away from the round rod 691. The pointed shovel 693 has a triangular design. When the seeder is operating, the triangular pointed shovel is carried into the soil as the seeder moves forward. Due to its sharp tip, it can easily cut into the soil. Even if it encounters hard soil clods or crop residues, it can break or push them away with its sturdy structure and triangular wedging action, creating good conditions for subsequent sowing and fertilization. Furthermore, the triangular pointed shovel 693 moves forward continuously in the soil, squeezing the soil to both sides to form a grove with the required width and depth. The round rod 691 and the connecting rod 692 rotate. The connecting rod 692 is fixedly connected to a guide plate 694 near the outer side of the pointed shovel 693. When the pointed shovel 693 cuts into the soil, the inclined guide plate 694 allows the soil to flow to both sides at a certain angle along its surface. Due to soil loosening and machine vibration, some soil may flow back into the already dug trench. At this time, the guide plate 694 can also act as a barrier to reduce soil backflow, keeping the trench clear and facilitating subsequent sowing and covering operations. There are two guide plates 694, symmetrically arranged around the connecting rod 692. A connecting rod 695 is fixedly connected to the outer side of the connecting rod 692 near the round rod 691. The end of the connecting rod 695 away from the connecting rod 692 is rotatably connected to a middle rod 69. 6. A slider 697 is fixedly connected to the end of the intermediate rod 696 away from the connecting rod 695. The slider 697 is located inside the slide groove 68, and the slider 697 and the slide groove 68 are slidably connected. A compression spring 698 is fixedly connected to the side of the slider 697 near the intermediate rod 696. During the use of the equipment, the pointed shovel 693 will continuously come into contact with the soil and be impacted. By setting the compression spring 698, it can play a role in buffering and shock absorption, reducing the impact force transmitted by the pointed shovel 693 to other parts of the seeder, thereby reducing the wear of various parts and extending the service life of the seeder. At the same time, when the pointed shovel 693 encounters hard objects such as stones or tree roots, the compression spring 698 is compressed, causing the connecting rod 692 and the connecting rod 695 to rotate. At this time, the connecting rod 692 drives the connecting rod 695 to rotate. The folding of the pointed shovel 693 prevents it from colliding with hard objects and causing damage, thus effectively protecting the shovel 693 and related components of the seeder, reducing maintenance costs and downtime. The round rod 691 drives the connecting rod 692 and the slider 697 downwards, causing the pointed shovel 693 to move downwards. As the depth of penetration increases, the volume and area of ​​soil in contact with the shovel also increase, leading to increased friction and normal pressure from the soil. Simultaneously, the slider 697 slides on the trapezoidal block 65, compressing the compression spring 698. This adjusts the folding elasticity, adjusting the pressure value of the folding rotation according to the planting depth. The end of the compression spring 698 furthest from the slider 697 is fixedly connected to the connecting rod 695.An intermediate plate 699 is fixedly connected to the top of the intermediate rod 696, and one end of the intermediate plate 699 is fixedly connected to the end of the round rod 691 near the connecting rod 692.

[0037] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 8 As shown, the flattening component 5 includes a gear 51 located at the end of the housing 3 away from the adjusting component 6. A rotating shaft 52 is fixedly connected to the outer side of the gear 51. There are multiple gears 51, which are symmetrically arranged around the rotating shaft 52. A circular plate 53 is fixedly connected to the outer side of the rotating shaft 52. There are multiple circular plates 53. A limit rod 55 is fixedly connected to the outer side of the circular plate 53. The main body 1 drives the housing 3 to move through the connecting block 2 and the fixing block 61, so that the housing 3 drives the circular plates 53 to rotate. During the rolling process, the circular plates 53 rely on their own weight to flatten the soil surface. The surface is compacted to flatten and level the loose and uneven soil surface after tilling, providing a relatively flat seedbed for subsequent sowing. This facilitates even sowing and covering of seeds, improving sowing quality. There are multiple limiting rods 55, which are evenly distributed on the circular plate 53 with the rotating shaft 52 as the center. Limiting components 54 are fixedly connected to the outside of the rotating shaft 52. There are multiple limiting components 54, and the circular plates 53 and limiting components 54 are alternately arranged. Cleaning components 56 are provided on the outside of the circular plate 53, and the two ends of the cleaning components 56 are fixedly connected to the two ends of the rotating shaft 52.

[0038] The limiting component 54 includes a positioning plate 541, which is fixedly connected to the rotating shaft 52. The positioning plate 541 is located at the interval between two adjacent circular plates 53. A square hole 542 is provided on the outer side of the positioning plate 541. When the circular plates 53 rotate, the edge limiting rod 55 also rotates accordingly. During its rotation, it can further turn and stir the soil. At the same time, the rotating shaft 52 drives the pressure plate 544 to rotate, so that it directly contacts the soil. Using its own weight and the elastic force of the return spring 543, the soil is made more compact. The limiting rod 55 and the pressure plate 544 and the return spring 543 are used to make the soil more compact. The combined effect of spring 543 can make the soil mix more evenly, improve the soil structure, increase the soil aeration and permeability, create better soil conditions for plant growth, and provide a good soil foundation for subsequent sowing or other agricultural operations. There are multiple square holes 542, which are evenly distributed around the rotating shaft 52. The inner wall of the square hole 542 is fixedly connected to a return spring 543. The end of the return spring 543 away from the square hole 542 is fixedly connected to a pressure plate 544, and the pressure plate 544 is slidably connected to the square hole 542.

[0039] The cleaning component 56 includes a ring 561, which is fixedly connected to a rotating shaft 52. A limit block 562 is fixedly connected to the outer side of the ring 561, and a protective shell 563 is fixedly connected to the top of the limit block 562. A slot 564 is formed on the inner wall of the protective shell 563, and a locking block 565 is provided on the inner wall of the slot 564. The locking block 565 is L-shaped and elastic. There are two locking blocks 565, which are symmetrically arranged. The protective shell 563 interacts with the scraper 5 through the cooperation between the slot 564 and the locking blocks 565. 66 is engaged. As the circular plate 53 and the positioning plate 541 rotate with the rotating shaft 52, the scraper 566 and the cleaning brush 567 clean the outer side of the circular plate 53 and the positioning plate 541 to prevent soil from accumulating on the circular plate 53 and ensure that the surface of the circular plate 53 is clean, so that it can continuously and effectively compact and turn the soil. The end of the locking block 565 away from the locking groove 564 is fixedly connected to the scraper 566, which contacts the outer side of the circular plate 53. The side of the scraper 566 near the positioning plate 541 is fixedly connected to the cleaning brush 567.

[0040] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 10As shown, the feeding assembly 4 includes a housing 41, which is fixedly connected to the top of the fixing block 61. A motor 48 is fixedly connected to the outer side of the housing 41, and a rotating rod 411 is rotatably connected to the inner wall of the housing 41. The output end of the motor 48 passes through the housing 41 and is fixedly connected to the rotating rod 411. A spiral plate 49 is fixedly connected to the outer side of the rotating rod 411. The rotating plate 45 is located inside the circular frame 42 and the circular groove 62, which form a circle. Seeds are placed inside the housing 41. The motor 48 is powered by an external power source and drives the rotating shaft 44 to rotate. The rotating shaft 44 drives the spiral plate 49 to rotate, so that the seeds are evenly distributed on the inner bottom of the housing 41. Then, the seeds fall into the slot 46 on the rotating plate 45 through the through hole 410 at the bottom. The rotating plate 45, driven by the rotation of the transmission wheel 43, moves the seeds away from the housing. At the same time, the circular frame 42 restricts the excess seeds in the slot 46, so that a certain amount of seeds move to the circle. The seeds are discharged from the top of the tube 47 under the action of gravity, and then sown. By sowing seeds quantitatively, the problem of seedlings growing too densely or too sparsely due to too much or too little sowing is avoided, providing a good population structure for crop growth, which is conducive to improving crop yield and quality. The bottom of the outer shell 41 is fixedly connected to a circular frame 42. The inside of the circular frame 42 is equipped with a transmission wheel 43. The outer side of the transmission wheel 43 is fixedly connected to a rotating shaft 44. The transmission wheel 43 is symmetrically arranged with the rotating shaft 44 as the center. The transmission wheel 43 is connected to the gear 51 through a transmission belt. The outer side of the rotating shaft 44 is fixedly connected to a rotating plate 45. The outer side of the rotating plate 45 has a slot 46. There are multiple rotating plates 45, which are evenly distributed on the rotating shaft 44. The bottom of the circular frame 42 is fixedly connected to a circular tube 47, which communicates with the circular frame 42. The bottom of the outer shell 41 has a through hole 410, which is located on the same vertical plane as the rotating plate 45.

[0041] In use, the seeds are placed inside the outer casing 41. The motor 48 is powered by an external power source. The motor 48 drives the rotating shaft 44 to rotate, which in turn drives the spiral plate 49 to rotate, so that the seeds are evenly distributed on the inner bottom of the outer casing 41. Then, the seeds fall through the through hole 410 at the bottom into the slot 46 on the rotating plate 45. The rotating plate 45, driven by the rotation of the transmission wheel 43, drives the seeds to leave the outer casing. At the same time, the circular frame 42 restricts the excess seeds in the slot 46, so that a certain amount of seeds move to the top of the circular tube 47. Thus, the seeds are discharged from the circular tube 47 under the action of gravity, and then sown.

[0042] The main body 1 moves, allowing the equipment to travel on both sides of the soil ridge. At this time, the seeder is used for sowing on the soil ridge. Since the seed size, germination characteristics and root growth habits of different crops are different, there are specific requirements for the sowing depth. The hydraulic cylinder 63 works to adjust the fixed rod 67 to slide up and down inside the annular groove 66, which causes the round rod 691 on the fixed rod 67 to move downward inside the round hole 610. Thus, the round rod 691 drives the pointed shovel 693 to move through the connecting rod 692, thereby adjusting the sowing depth.

[0043] During operation, the pointed shovel 693 continuously contacts and impacts the soil. The compression spring 698 acts as a buffer, reducing the impact force transmitted from the pointed shovel 693 to other parts of the seeder, thus reducing wear and tear and extending the seeder's lifespan. Furthermore, when the pointed shovel 693 encounters hard objects such as stones or tree roots, the compression spring 698 compresses, causing the connecting rod 692 and connecting rod 695 to rotate. At this time, the connecting rod 692 causes the pointed shovel 693 to fold, preventing direct contact with hard objects and thus reducing stress. Damage to the pointed shovel 693 effectively protects the pointed shovel 693 and related components of the seeder, reducing maintenance costs and downtime. The round rod 691 drives the connecting rod 692 and the slider 697 to move downwards, and the pointed shovel 693 moves downwards. As the depth of the pointed shovel 693 into the soil increases, the volume and area of ​​soil in contact with the pointed shovel 693 also increase accordingly. The friction and normal pressure of the soil on the pointed shovel 693 will increase with the increase of depth. At the same time, the slider 697 slides on the trapezoidal block 65, causing the compression spring 698 to be compressed. At this time, the elastic force of the folding is adjusted.

[0044] When the circular plate 53 rotates, the edge limiting rod 55 also rotates. During its rotation, the soil can be further turned over and stirred. At the same time, the rotating shaft 52 drives the pressure plate 544 to rotate, so that it comes into direct contact with the soil. Using its own weight and the elastic force of the return spring 543, the soil becomes more compact. By combining the action of the limiting rod 55 with the pressure plate 544 and the return spring 543, the soil can be mixed more evenly.
