Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and more specifically, to an agricultural sowing device. Background Technology

[0002] Agricultural seeding devices are a new type of agricultural machinery that replaces traditional manual seeding operations. Some of these are general-purpose seeders that can be used for sowing multiple crops. To adapt to different soil textures and the sowing depth requirements of various crops, they are equipped with a plowshare. The plowshare can open appropriate furrows on different plots of land and then sow seeds according to the sowing parameters corresponding to the crop being sown. They are widely used in large-scale farmland where cultivation is relatively extensive. When agricultural seeding devices encounter severely compacted soil, they first use a plowshare to vibrate and till the soil to create furrows. However, existing plowshares can usually only vibrate up and down. This method is limited by soil hardness and structure, especially in dry, compacted soil or soil with many roots. When the plowshare vibrates up and down while tilling the soil, the soil is not broken up sufficiently. Sometimes the soil is only compacted downwards, resulting in a "plow pan" phenomenon, which hinders water penetration, air circulation, and the downward growth of crop roots. Furthermore, the angles on both sides of the plowshare in existing technologies are fixed and lack flexible adjustment capabilities. This makes it difficult to meet the different cultivation requirements of various crops based on soil conditions. It is impossible to use large-angle tillage for deep-rooted crops (such as carrots and sweet potatoes) or to reduce the angle for shallow-rooted crops (such as wheat and corn).

[0003] To solve the above problems, the inventors proposed an agricultural seeding device. Summary of the Invention

[0004] To solve the above-mentioned technical problems, an agricultural seeding device is provided, and this technical solution solves the problems mentioned in the background art. To achieve the above objectives, the present invention can be implemented using the following technical solutions: The present invention provides an agricultural sowing device, including a sowing vehicle, a support fixedly connected to the sowing vehicle, a sowing mechanism provided on the side of the support away from the sowing vehicle, and a support column fixedly connected to the support. The support frame is equipped with a vibration assembly, which includes a motor fixedly connected to a support column. The output shaft of the motor is fixedly connected to a synchronous pulley 1. The synchronous pulley 1 is connected to a synchronous pulley 2 via a synchronous belt drive. A connecting rod disc is fixedly connected to the synchronous pulley 2. An eccentric column is fixedly connected to the eccentric position of the connecting rod disc away from the synchronous pulley 2. Two support plates are fixedly connected to the inner side wall of the support frame. Two limiting frames are symmetrically fixedly connected to one of the support plates. The two limiting frames are slidably connected to a cross rod. A striking hammer is provided on the cross rod. Two sliding plates are symmetrically fixedly connected to the inner side wall of the support frame. The two sliding plates are slidably connected to a buffer plate. Multiple springs are fixedly connected between the buffer plate and the support frame. A frame is provided between the buffer plate and the cross rod. Four plow frames are fixedly connected at equal intervals at the bottom of the frame.

[0005] Preferably, the vibration assembly further includes a disc fixedly connected to the output shaft of the motor, the disc being rotatably connected to the support column, a short connecting rod being rotatably connected to an eccentric position on the side of the disc away from the motor, a slider being rotatably connected to the end of the short connecting rod away from the disc, the slider having a sliding groove, the sliding groove being slidably connected to the frame, and a guide rail being fixedly connected to the side of the support column near the disc, the guide rail being slidably connected to the slider.

[0006] Preferably, one of the support plates is rotatably connected to the synchronous pulley, the other support plate is rotatably connected to the connecting rod disc, the cross rod is adapted to the eccentric column, and the cross rod is provided with three striking hammers made of rubber.

[0007] Preferably, each of the plow frames is provided with an adjustment assembly, the adjustment assembly including a plowshare head fixedly connected to the plow frame, each plow frame having three square holes equidistantly opened, each plowshare head having two angle-adjusting blades rotatably connected to the side near the square holes, each angle-adjusting blade having a connecting rod rotatably connected to the side near the plow frame, the ends of the two connecting rods away from the angle-adjusting blades being rotatably connected to a cavity block, a pin being slidably connected to the inner cavity of the cavity block, and a compression spring and a stop bar being fixedly connected to the inner cavity of the cavity block, with two compression springs and two stop bars symmetrically arranged.

[0008] Preferably, the cavity block is slidably connected to the plow frame, the pin is adapted to the square hole, a handle is fixedly connected to the pin, and every two compression springs are fixedly connected to the adjacent pin.

[0009] Preferably, the frame is provided with a perforation assembly, the perforation assembly includes a fixing frame fixedly connected to the frame, the outer wall of the fixing frame has a circular hole, a plurality of circular holes are symmetrically arranged, two cavity blocks are symmetrically slidably connected to the fixing frame, the two cavity blocks are jointly fixedly connected to a T-shaped plate, and a plurality of spikes are uniformly fixed on the T-shaped plate.

[0010] Preferably, the perforation assembly further includes a pin two slidably connected to the inner cavity of each cavity block two, and a combination block is fixedly connected to the side of the pin two away from the circular hole. The combination block is composed of a rectangular plate and a cylinder. A compression spring two is fixedly connected to the inner cavity of the cavity block two, and a limit hole is formed on the outer wall of the cavity block two.

[0011] Preferably, the second pin is adapted to the round hole, and a handle is fixedly connected to the assembly block.

[0012] As described above, the advantages of the present invention are: Through the reciprocating movement of the crossbar and the cooperation between the spring and the buffer plate, the adjustable-angle plowshare formed by the plowshare head and the angle-adjusting blade can vibrate laterally when tilling the soil. Compared with the existing plowshares that can only vibrate up and down, this device uses the plowshare head and the angle-adjusting blade to move up and down, in coordination with the hammer on the crossbar to reciprocate and strike the frame, so that the plowshare head and the angle-adjusting blade can vibrate up and down and laterally. The lateral vibration of the plowshare head and the angle-adjusting blade further breaks down the soil through shearing and lateral disturbance, which can more effectively break up large soil clods and improve the fineness of hard soil. In this way, the formation of "plow pan" is prevented, ensuring that the plowshare of the agricultural seeding device can open furrows smoothly.

[0013] By moving the cavity block, the opening and closing angles of the angle-adjusting blades on both sides of the plowshare head can be adjusted, thus forming an adjustable-angle plowshare. Compared with the existing technology where the plowshare is fixedly installed on both sides, this device can adjust the opening and closing angles of the plowshare head according to the needs of sowing crops, thus solving the problem that the existing technology, which uses fixed installation on both sides of the plowshare, cannot adjust the opening and closing angles according to the specific needs of sowing crops, resulting in a single working effect when tilling the soil. In addition, the cooperation and fixation between the pin, the spring and the square hole ensures that the plowshare remains stable after the angle is adjusted, which can further meet the needs of the plowshare for precise furrowing of different seeds.

[0014] By moving the spikes up and down, the soil is perforated before sowing. Compared to existing technologies that sow directly after tilling, this device utilizes an adjustable-angle plowshare formed by the plowshare head and adjustable blades. During tilling, the plowshare vibrates both up and down and laterally, driving the spikes to penetrate the soil. The lateral vibration during penetration creates tiny air-permeable spaces, enhancing soil respiration and improving the ventilation and water permeability of deeper soil layers. This promotes healthy root growth and improves the ecological properties of the sowing layer. The soil around the seeds becomes more permeable and aerated after sowing, solving the problem of low nutrient absorption efficiency for seeds in the "plow pan" when sowing directly after tilling. This allows agricultural machinery to produce additional benefits, thereby improving the ecological properties of the soil. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] The embodiments provided by the present invention will be described in detail below: An agricultural seeding device, such as Figure 1 As shown, it includes a seeding vehicle 1, a support 2 fixedly connected to the seeding vehicle 1, and a seeding mechanism set on the side of the support 2 away from the seeding vehicle 1. The seeding mechanism is a known existing technology and usually consists of a seed box, a seeder, etc. The seed box is used to store seeds, and the seeder is responsible for sowing the seeds into the soil at a set depth and spacing. A support column 21 is fixedly connected to the upper surface of the support 2. like Figures 2 to 4As shown, a vibration assembly is installed on the support 2. The vibration assembly includes a motor 31 fixedly connected to the support column 21. The output shaft of the motor 31 is fixedly connected to a synchronous pulley 32. The synchronous pulley 32 is connected to a synchronous pulley 33 via a synchronous belt. A shaft extends from the center of the synchronous pulley 33 on the side away from the motor 31. The other end of the shaft is coaxially fixedly connected to a connecting rod disc 34. An eccentric column 35 is fixedly connected to the eccentric position of the connecting rod disc 34 on the side away from the synchronous pulley 33. Two support plates 36 are provided on the inner side wall of the support 2 near the synchronous pulley 33 and the connecting rod disc 34. One of the support plates 36 is located on the side of the synchronous pulley 33 away from the connecting rod disc 34, and the synchronous pulley 33 is rotatably connected to the support plate 36. The other support plate 36 is located on the side of the connecting rod disc 34 near the shaft. The shaft passes through the support plate 36 and is rotatably connected. Two limiting frames 37 are symmetrically fixedly connected to one side of the eccentric column 35. The two limiting frames 37 are slidably connected to a cross rod 38. The limiting frames 37 are used to restrict the movement direction of the cross rod 38, so that the cross rod 38 can only slide laterally. The cross rod 38 has a groove structure in the vertical direction. The eccentric column 35 is slidably set inside the groove structure. A hammer is fixedly connected to one end of the cross rod 38 that passes through one of the limiting frames 37. Two symmetrical sliding plates 39 are fixedly connected to the inner wall of the bracket 2 away from the support plate 36. The two sliding plates 39 are slidably connected to a buffer plate 310. Multiple springs 311 are fixedly connected between the buffer plate 310 and the bracket 2. The springs 311 are arranged in a rectangular equidistant pattern. A frame 312 is set between the buffer plate 310 and the cross rod 38. Multiple plow frames 313 are fixedly connected at equal intervals on the bottom surface of the frame 312. In this embodiment, four plow frames 313 are provided.

[0019] Furthermore, such as Figure 2 and Figure 5 As shown, the vibration assembly also includes a disc 314 fixedly connected to the output shaft of the motor 31. The disc 314 is located on the side of the support column 21 away from the synchronous pulley 32. The disc 314 is rotatably connected to the support column 21. A short connecting rod 315 is rotatably connected to the eccentric position of the disc 314 away from the motor 31. A slider 316 is rotatably connected to the end of the short connecting rod 315 away from the disc 314. A groove 317 is provided on the outer wall of the slider 316 away from the support column 21. The groove 317 is slidably connected to the frame 312. The frame 312 can move laterally along the trajectory of the groove 317. A guide rail 318 is fixedly connected to the side of the support column 21 near the disc 314. The guide rail 318 is located directly below the disc 314. The guide rail 318 is slidably connected to the slider 316. The slider 316 can move vertically along the guide rail 318.

[0020] Furthermore, such as Figure 2As shown, one of the support plates 36 is rotatably connected to the synchronous wheel 33, and the other support plate 36 is rotatably connected to the connecting rod disc 34. The sliding groove structure of the cross rod 38 is adapted to the eccentric column 35. When the connecting rod disc 34 rotates, the eccentric column 35 performs circular motion, thereby driving the cross rod 38 to reciprocate laterally. The cross rod 38 and the buffer plate 310 are both located on the path of the frame 312 moving up and down. Three hammers are provided on the cross rod 38 and the material is rubber. Through the elasticity and flexibility of the rubber material, the reaction force of the frame 312 on the hammers and the cross rod 38 is reduced when the hammers reciprocate laterally and strike the frame 312.

[0021] Furthermore, such as Figures 6 to 8 As shown, each plow frame 313 is equipped with an adjustment assembly, which includes a plowshare head 41 fixedly connected to the plow frame 313. Each plow frame 313 has three square holes 42 equidistantly spaced. Two angle-adjusting blades 43 are rotatably connected to the side of each plowshare head 41 near the square holes 42. Each angle-adjusting blade 43 is rotatably connected to a connecting rod 44 near the side wall of the plow frame 313. The ends of the two connecting rods 44 away from the angle-adjusting blades 43 rotate together. A cavity block 45 is connected, and a pin 46 is slidably connected to the inner cavity of the cavity block 45. The part of the pin 46 away from the inner cavity of the cavity block 45 is located inside the square hole 42. A compression spring 47 is fixedly connected between the inner cavity of the cavity block 45 and the pin 46. The compression spring 47 is in a compressed state. A stop bar 48 is fixedly connected to the inner cavity of the cavity block 45. The stop bar 48 is used to restrict the movement of the pin 46. There are two symmetrically arranged compression springs 47 and stop bars 48.

[0022] Furthermore, such as Figure 7 and Figure 8 As shown, the cavity block 45 is slidably connected to the outer surface of the plow frame 313. By moving the position of the cavity block 45, the opening and closing angles of the two angle adjustment blades 43 can be adjusted. The pin 46 is adapted to the square hole 42. A handle is fixedly connected to one side of the pin 46 that protrudes from the cavity block 45. The pin 46 can be moved by the handle. Every two compression springs 47 are fixedly connected to the adjacent pin 46.

[0023] Furthermore, such as Figures 9 to 11 As shown, a perforation assembly is provided on the frame 312. The perforation assembly includes a fixing frame 51 fixedly connected to the frame 312. The fixing frame 51 is located on the side of the frame 312 away from the slider 316. A circular hole 52 is opened on the outer wall of the fixing frame 51. Multiple circular holes 52 are symmetrically arranged. Two hollow blocks 53 are symmetrically slidably connected to the outer surface of the fixing frame 51. An inverted T-shaped plate is fixedly connected to the two hollow blocks 53. Multiple spikes 54 are evenly fixed on the T-shaped plate. The spikes 54 are used to pierce the soil after it has been turned over.

[0024] Furthermore, such as Figure 10 and Figure 11 As shown, the perforation assembly also includes a pin 2 55 slidably connected to the inner cavity of each cavity block 2 53. The pin 2 55 is used to fix the cavity block 2 53. By adjusting the position of the cavity block 2 53, the depth of the spike 54 piercing the soil can be adjusted. A combination block 56 is fixedly connected to the side of the pin 2 55 away from the circular hole 52. A compression spring 2 57 is fixedly connected to the side of the inner cavity of the cavity block 2 53 away from the pin 2 55. The compression spring 2 57 is sleeved on the outside of the combination block 56. The combination block 56 is composed of a rectangular plate and a cylinder. A limiting hole 58 is opened on the outer wall of the cavity block 2 53. The limiting hole 58 is connected to the inner cavity of the cavity block 2 53, and the rectangular plate in the combination block 56 is located in the limiting hole 58.

[0025] Furthermore, such as Figure 11 As shown, the second pin 55 is adapted to the round hole 52. The part of the second pin 55 that is away from the inner cavity of the second cavity block 53 is located inside the round hole 52. The end of the assembly block 56 that protrudes from the second cavity block 53 is fixedly connected to a handle, and the second pin 55 can be moved by the handle.

[0026] During work: The angle-adjusting blades 43 on both sides of the plowshare head 41 in this device can adjust the angle, and the plowshare head 41 can vibrate laterally while vibrating vertically. The detailed steps are as follows: When sowing is required, first adjust the depth of the spike 54 penetrating the soil: The worker holds one of the hollow blocks 53 by hand and then pulls the handle on the assembly block 56 outward. This causes the assembly block 56 and the second pin 55 to move along the limiting hole 58 towards the side away from the circular hole 52. When the rectangular plate in the assembly block 56 is completely separated from the inner cavity of the hollow block 53 and the limiting hole 58, the cylinder in the assembly block 56 remains within the limiting hole 58. At this point, the second pin 55 has completely left the circular hole 52 and is completely positioned within the inner cavity of the hollow block 53. In the middle, and the compression spring 57 is in the compressed state, the operator then turns the handle 90 degrees, causing the assembly block 56 and the pin 55 to rotate 90 degrees together with the handle. Then the operator releases the handle, and the compression spring 57 in the compressed state causes the assembly block 56 to move towards the side closer to the round hole 52. However, since the rectangular plate in the assembly block 56 has already rotated 90 degrees, it cannot pass through the limiting hole 58 and is stuck on the outside of the limiting hole 58, thus keeping the assembly block 56 and the pin 55 stationary.

[0027] The above steps are then repeated for the other cavity block 53. After the pins 55 in both cavity blocks 53 are disengaged from the round holes 52, the operator can push or pull the cavity block 53 upward or downward along the outer surface of the fixing frame 51, so that the cavity block 53 drives the spike 54 to move vertically upward or downward, thereby adjusting the depth of the spike 54 into the soil as needed. When the spike 54 is adjusted to a suitable height, the pins 55 are aligned with the round holes 52. Then, the operator reverses the handle on the assembly block 56 in turn, so that the assembly block 56 and the pins 55 rotate 90 degrees together with the handle. With the help of the spring 57 in the compressed state, the pins 55 are inserted into the round holes 52, thereby fixing the spike 54 in this position. In this way, the depth of the spike 54 into the soil can be adjusted by moving the position of the cavity block 53.

[0028] Then, the opening and closing angles of the angle-adjusting vanes 43 on both sides of the plowshare head 41 are adjusted: The worker holds the hollow block 45 with their hand and pulls the handle on the pin 46 outwards, causing the handle to move the pin 46 away from the square hole 42. When the pin 46 contacts the stop bar 48, the pin 46 is completely disengaged from the square hole 42. At this time, the compression spring 47 is compressed. Then, the worker can push the hollow block 45 along the outer surface of the plow frame 313, causing the hollow block 45 to move along the outer surface of the plow frame 313 towards the plow head 41. During the movement of the hollow block 45 along the outer surface of the plow frame 313, the adjusting vane 43 rotates around the rotational connection point with the plow head 41 as an axis, away from the plow frame 313, through the connecting rod 44. The worker can choose which square hole 42 the hollow block 45 should move to according to the needs of the soil conditions for sowing crops.

[0029] After the worker moves the cavity block 45 to the position of the square hole 42, he releases the handle on the pin 46. With the help of the spring 47 in the compressed state, the pin 46 is inserted into the square hole 42, thereby fixing the opening and closing angle of the angle-adjusting blades 43 on both sides of the plowshare head 41. This makes the plowshare head 41 and the angle-adjusting blades 43 more stable after the angle is adjusted. Furthermore, the plowshare head 41 and the angle-adjusting blades 43 on both sides combine to form an adjustable-angle plowshare. In this way, by adjusting the opening and closing angle of the angle-adjusting blades 43 on both sides of the plowshare head 41, the adjustable-angle plowshare can meet the needs of different crop sowing soil conditions. For example, a large angle of cultivation can be used for deep-rooted crops such as carrots and sweet potatoes, while a smaller angle of cultivation can be used for shallow-rooted crops such as wheat and corn.

[0030] In the above process, the opening and closing angles of the angle-adjusting blades 43 on both sides of the plowshare head 41 are adjusted by the movement of the cavity block 45, thus forming an adjustable-angle plowshare. Compared with the existing technology that uses a fixed installation method on both sides of the plowshare, this device utilizes three square holes 42 on the plow frame 313. When the cavity block 45 moves to different positions of the square holes 42, the angle-adjusting blades 43 are pushed and pulled by the connecting rod 44, so that the opening and closing angles of the angle-adjusting blades 43 on both sides of the plowshare head 41 are different. The opening and closing angles of the plowshare head 41 can be adjusted according to the needs of sowing crops, forming an adjustable-angle plowshare. This solves the problem of the existing technology where the plowshare is fixed on both sides, making it impossible to adjust the opening and closing angle according to the specific needs of sowing crops, resulting in a single working effect when tilling the soil. In addition, the cooperation and fixation between the pin 46, the compression spring 47 and the square hole 42 ensures that the plowshare remains stable after the angle is adjusted. In this way, the plowshare can further meet the needs of precise furrowing for different seeds.

[0031] When tilling and sowing are required, the operator enters the cab of the sowing vehicle 1 and drives it slowly, causing the plowshare formed by the plow head 41 and the angle-adjusting blade 43 to cut into the soil for tilling. At the same time, the sowing mechanism is started for sowing, and the motor 31 is started by the controller, causing the output shaft of the motor 31 to rotate forward. When the output shaft of the motor 31 rotates forward, it drives the disc 314 to rotate forward together with the output shaft of the motor 31. During the forward rotation of the disc 314, the short connecting rod 315 pushes and pulls the slider 316 back and forth, causing the slider 316 to move up and down along the guide rail 318. The slider 316 drives the frame 312 and the plow head 41 and the angle-adjusting blade 43 to move up and down together, so that the adjustable-angle plowshare formed by the plow head 41 and the angle-adjusting blade 43 vibrates up and down during the tilling process.

[0032] While the output shaft of motor 31 rotates forward, it drives synchronous pulley 32 to rotate forward together with the output shaft of motor 31. Synchronous pulley 32 drives synchronous pulley 33 to rotate together with synchronous pulley 32 through synchronous belt. Synchronous pulley 33 drives connecting rod disc 34 to rotate together. During the forward rotation of connecting rod disc 34, the eccentric column 35 on the surface of connecting rod disc 34 performs circular motion, thereby pushing and pulling cross rod 38 back and forth. This causes cross rod 38 to move back and forth laterally along limit frame 37, further causing the rubber hammer on cross rod 38 to repeatedly strike frame 312.

[0033] During the process of the hammer on the cross bar 38 striking the frame 312, the frame 312 is impacted by the hammer and moves along the slide groove 317 towards the side closer to the buffer plate 310. When the frame 312 contacts the buffer plate 310, it is still in a moving state and will further push the buffer plate 310, causing the buffer plate 310 to compress the spring 311. When the cross bar 38 and the hammer return to their original positions, the rebound force of the spring 311 pushes the frame 312 along the slide groove 317 towards the side away from the buffer plate 310. When the frame 312 moves to its initial position, it will be subjected to... When the hammer strikes, the crossbar 38 moves back and forth laterally, causing the hammer to strike the frame 312 back and forth. This causes the frame 312 to move back and forth laterally along the groove 317. As a result, the frame 312 drives the plowshare 41 and the angle-adjusting blade 43 at the bottom to move laterally while moving vertically. This makes the adjustable-angle plowshare formed by the plowshare 41 and the angle-adjusting blade 43 vibrate not only vertically but also laterally when tilling the soil. The lateral vibration introduces an additional horizontal breaking effect, causing the forces on the soil in two directions to be superimposed, which significantly improves the soil breaking effect.

[0034] In the above process, through the reciprocating movement of the crossbar 38 and the cooperation between the spring 311 and the buffer plate 310, the adjustable-angle plowshare formed by the plowshare head 41 and the angle-adjusting blade 43 can vibrate laterally when tilling the soil. Compared with the existing plowshares that can only vibrate vertically, this device utilizes the vertical movement of the plowshare head 41 and the angle-adjusting blade 43, in conjunction with the reciprocating movement of the hammer on the crossbar 38, to strike the frame 312, causing the plowshare head 41 and the angle-adjusting blade 43 to vibrate both vertically and laterally. The lateral vibration of the plowshare head 41 and the angle-adjusting blade 43 further breaks down the soil through shearing and lateral disturbance, which can more effectively break up large soil clumps and improve the fineness of hard soil. This solves the problem in the existing technology where the plowshare can only vibrate up and down. In dry, compacted or root-rich plots, the soil is not broken up sufficiently and is only compacted downwards, thus forming a "plow bottom" during tillage, which is the phenomenon that the bottom layer of soil is compacted rather than effectively broken up. This prevents the formation of the "plow bottom" and ensures that the plowshare of the agricultural seeding device can open furrows smoothly.

[0035] When the frame 312 moves vertically along the guide rail 318 and laterally along the chute 317, the plowshare 41 and the angle-adjusting blade 43 vibrate up and down and laterally during tilling. This causes the spikes 54 fixed on the frame 312 to repeatedly pierce the soil as the frame 312 moves up and down, thereby perforating the soil. During the process of piercing the soil, the spikes vibrate laterally as the frame 312 moves laterally. By perforating the soil and vibrating laterally during the perforation process, the ventilation and permeability of the soil are improved.

[0036] In the above process, the up-and-down movement of the spikes 54 perforates the soil before sowing. Compared with the existing technology of sowing directly after tilling, this device uses the plowshare head 41 and the angle-adjusting blades 43 to vibrate up-and-down and laterally during tilling, which drives the spikes 54 to penetrate the soil. During the penetration process, the lateral vibration creates tiny air-permeable spaces, enhancing soil respiration and improving the ventilation and water permeability of deep soil. This promotes healthy root growth and improves the ecological properties of the sowing layer soil, making the soil around the seeds more permeable and aerated after sowing. This solves the problem of low nutrient absorption efficiency of seeds in the "plow layer" when sowing directly after tilling in the existing technology. In this way, agricultural power machinery can produce additional effects, thereby improving the ecological properties of the soil.

[0037] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
