Description

Technical Field

[0001] This invention relates to the field of tree planting technology, and in particular to a soil compaction device for windbreak and sand-fixing forest afforestation. Background Technology

[0002] Windbreak and sand-fixing forests are a type of protective forest created to prevent wind erosion and desertification and to stabilize shifting sand. Their main function is to resist wind and sand erosion, protect farmland, pastures, railways, highways, canals, reservoirs, and other facilities, and prevent the expansion of desertification. Windbreak and sand-fixing forests typically use trees, shrubs, and perennial herbaceous plants to form patches, strips, or blocks of artificial vegetation. Sometimes, sand barriers are added to change the near-surface aerodynamic conditions and protect the plants. These protective forests can effectively reduce wind speed, intercept sand particles, and trap surface sand particles through plant roots, thereby achieving the purpose of stabilizing shifting sand.

[0003] In afforestation efforts for sand fixation in arid and semi-arid regions, newly planted seedlings have unstable root systems and are highly susceptible to wind erosion and sand burial. Compacting the backfill soil around the seedling roots is one of the key steps to improve seedling survival rates.

[0004] Traditional or existing compaction equipment or methods typically employ a simple up-and-down pressing method during operation. This method has the following technical drawbacks: low compaction efficiency, and vertical pressing tends to cause sand and soil to disperse around the sapling rather than converge towards the center, which makes it ineffective in creating a supporting mound for the sapling, especially in shaping it to facilitate sand fixation and water collection. Secondly, after compaction, the surface of sandy soil tends to have irregular bumps and depressions. This uneven surface is not only aesthetically unappealing, but more importantly, it has poor water retention, making it unable to effectively guide rainwater or condensation to the roots of the seedlings. Summary of the Invention

[0005] This application provides a soil compaction device for windbreak and sand-fixing forest afforestation, solving the problems of low compaction efficiency in existing technologies. Furthermore, vertical compaction often causes sand to disperse around the seedlings rather than converging towards the center, resulting in poor effectiveness in creating supportive mounds for the seedlings, particularly in shaping them for sand fixation and water collection. After compaction, the sand surface tends to exhibit irregular bumps and depressions. This uneven surface is not only aesthetically unappealing but, more importantly, has poor water retention, failing to effectively guide rainwater or condensation towards the seedling roots. This system utilizes a tilted telescopic rod to drive an arc-shaped pressure plate, which not only compacts the sand but also effectively gathers the sand around the seedling towards the center. This solves the problem of traditional top-and-bottom pressing methods that result in sand scattering in all directions and poor central gathering. It also helps prevent wind and sand, protecting the seedling roots. Its sloping structure facilitates the collection of rainwater and dew to the seedling roots, improving water utilization. The pressure plate can be rotated slightly by an electric slide, allowing for micro-leveling of the soil surface, making it smooth, aesthetically pleasing, and with better water retention. It also helps regulate the even distribution of sand around the seedling.

[0006] This application provides a soil compaction device for afforestation of windbreak and sand-fixing forests, including a compaction component, which includes an outer frame, a pressure plate, a telescopic rod, and an electric sliding table; Both the outer frame and the pressure plate are curved, and the pressure plate has a right-angled triangle cross-section. The electric slide table is fixed to the inner wall of the outer frame, and one end of the telescopic rod is fixed to the slider of the electric slide table. The pressure plate is located at the end of the telescopic rod furthest from the electric slide table; The telescopic rod is set at an angle, and the electric slide is arc-shaped; There are two compaction components, and the outer frames inside the two compaction components fit together to form a ring; The two pressure plates inside the two compaction components fit together to form a ring; The telescopic rod extends and retracts, causing the pressure plate to tilt downwards and press down on the sand around the sapling; The electric slide is used to drive the telescopic rod and pressure plate to rotate in an arc, leveling the sand around the seedling.

[0007] As an improvement, the outer frames inside the two compaction components fit together to form a cylindrical shape that runs through their axis. With the pressure plate tightly attached to the sandy soil around the sapling, the axis of the pressure plate and the axis of the outer frame are on the same straight line; When the telescopic rod moves the pressure plate up and down, the axis of the pressure plate is parallel to the axis of the outer frame; When the electric slide table drives the pressure plate to rotate in an arc, the rotation axis of the pressure plate and the axis of the outer frame are on the same straight line. When the telescopic rod is at the center of the electric slide, the electric slide drives the pressure plate to rotate clockwise and counterclockwise by an angle of 0 to 30 degrees.

[0008] As an improvement, the hypotenuse of the right triangle is located below the pressure plate; After the pressure plates in the two compaction components are pressed together and pressed against the sand around the sapling, the sand around the sapling forms a frustum shape.

[0009] As improvements, a walking vehicle and a robotic arm are also included; There are two robotic arms, and each robotic arm corresponds to one of the two compaction components. Two robotic arms are symmetrically fixed on the traveling vehicle; The vehicle is a tracked vehicle; The compaction component is fixed to the output end of the robotic arm, and the outer ring of the outer frame is fixed to the output end of the robotic arm; Both the traveling vehicle and the robotic arm are used to adjust the pressing position of the compaction component.

[0010] As an improvement, the compaction assembly also includes an observation port; An observation port is provided on the side of the outer frame, and the observation port extends through the outer frame. The electric slide is located above the observation port.

[0011] As an improvement, the compaction assembly also includes a tension membrane and an exhaust mesh; Both the tension membrane and the exhaust net are arc-shaped. The lower end of the tension membrane is fixed to the inner wall of the outer frame, the lower end of the exhaust net is fixed to the upper end of the tension membrane, and the upper end of the exhaust net is fixed to the outer wall of the pressure plate.

[0012] As an improvement, it also includes bonding components, of which there are two, each corresponding to one of the two compaction components; The bonding assembly includes a mounting plate, a second tension membrane, a second exhaust mesh, a fixing rod, a positioning plate, and a fixing bladder; The mounting plate is arc-shaped and is fixed to the upper side of the pressure plate. The mounting plate is located at the arc-shaped opening of the pressure plate. The lower end of the second tension membrane is fixed to the side of the mounting plate, and the lower end of the second exhaust net is fixed to the upper end of the second tension membrane. The positioning plate is a cylindrical shape that runs through its axis, and the upper end of the exhaust mesh is fixed to the lower side of the positioning plate. There are two fixing rods, which are symmetrically fixed on both sides of the positioning plate. The end of the fixing rod away from the positioning plate is fixed to the inner wall of the outer frame. The fixation bladder is fixed to the inner ring of the positioning plate.

[0013] As an improvement, both exhaust mesh one and exhaust mesh two are made of non-woven fabric. Both the first and second stretch membranes are made of rubber. The lower end of the stretch membrane is fixed below the observation port; When the two pressure plates in the two compaction components are pressed together, the two tensile membranes can be pressed together to form a ring; When the two pressure plates in the two compaction components are in contact with each other, the two exhaust screens can be in contact with each other to form a ring; When the two pressure plates in the two compaction components are in contact with each other, the two mounting plates can be in contact with each other to form a hollow frustum shape along its axis, and the axis of the mounting plate and the axis of the pressure plate are on the same straight line; When the two pressure plates in the two compaction components are pressed together, the two tensile membranes can be pressed together to form a ring; When the two pressure plates in the two compaction components are in contact with each other, the two exhaust screens can be in contact with each other to form a ring; When the two pressure plates in the two compaction components are in contact with each other, the two positioning plates can be in contact with each other to form a hollow cylinder along its axis; When the two positioning plates within the two fitting components are fitted together, the two fixing bladders are fitted together; The axis of the positioning plate and the axis of the outer frame are on the same straight line.

[0014] As an improvement, auxiliary components are also included. There are two auxiliary components, each corresponding to one of the two compaction components. The auxiliary components include an airbag and an air pump. Airbag 1 is arc-shaped and fixed below the pressure plate. Airbag 1 is fixed on the inclined side of the pressure plate section. Air pump 1 is fixed on the pressure plate, and the output end of air pump 1 is connected to air bag 1.

[0015] As an improvement, the auxiliary components also include airbag two and air pump two; Airbag 2 is arc-shaped and fixed to the inner ring of the mounting plate. Air pump 2 is fixed to the outer ring of the mounting plate, and the output end of air pump 2 is connected to airbag 2.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: Firstly, the inclined telescopic rod drives the arc-shaped pressure plate to press down, which not only compacts the sand but also effectively gathers the sand around the seedling towards the center. This solves the problem of traditional top-and-bottom pressing causing the sand to disperse in all directions and have poor central gathering effect. It can also prevent wind and sand, protecting the seedling roots. Its sloping structure is conducive to collecting rainwater and dew to the seedling roots, improving water utilization. The pressure plate can be rotated slightly by an electric slide, which can micro-level the surface of the soil mound, making the surface smooth and beautiful with better water retention, and can also adjust the even distribution of sand around the seedling.

[0017] Secondly, a tension membrane 1, an exhaust net 1, a tension membrane 2, and an exhaust net 2 are installed between the pressure plate and the outer frame to form a retractable sealed cavity. When the pressure plate moves up and down to compact the sand, the internal air can be discharged through the exhaust net 1 and the exhaust net 2, but the smoke and dust are effectively intercepted to prevent them from escaping into the air and causing secondary pollution. When the two compaction components are closed, the internal fixing bladders can fit together and tightly wrap the trunk of the sapling to straighten it. When the pressure plate compacts and the rotating sand vibrates, it can firmly fix the sapling to prevent it from shaking, tilting, or falling over, thus ensuring the quality of tree planting.

[0018] Thirdly, when dealing with small areas of sand or needing to shape truncated cones of specific sizes, the first airbag can be inflated to increase the effective area and pressure of the compaction surface, flexibly adapting to the compaction needs of different sized mounds and improving the equipment's versatility. An second airbag is installed inside the mounting plate at the arc-shaped opening above the pressure plate. The second airbag gently conforms to the seedling, preventing direct collision damage from mechanical parts. The second airbag further compacts the sand at the arc-shaped opening of the pressure plate, ensuring that all areas around the seedling's roots are compacted, making the seedling more firmly and reliably fixed. By controlling the inflation pressure of the first and second airbags, the compaction degree at different locations of the mound can be finely adjusted. When encountering small, hard objects or stones, the first and second airbags deform, distributing the pressure more evenly across the surrounding sand, preventing shearing or crushing damage to the seedling roots.

[0021] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Example 1: As Figures 1-10 As shown, this application discloses a soil compaction device for afforestation of windbreak and sand-fixing forests, including a traveling vehicle 100, a robotic arm 200, and a compaction component 300. The compaction assembly 300 includes an outer frame 310, an observation port 311, a pressure plate 320, a telescopic rod 330, and an electric slide table 340; Both the outer frame 310 and the pressure plate 320 are arc-shaped, and the cross-section of the pressure plate 320 is a right-angled triangle; The hypotenuse of the right triangle is located below the pressure plate 320; The electric slide table 340 is fixed to the inner wall of the outer frame 310, and one end of the telescopic rod 330 is fixed to the slider of the electric slide table 340. The pressure plate 320 is located at the end of the telescopic rod 330 away from the electric slide table 340; The telescopic rod 330 is inclined, and the electric slide 340 is arc-shaped; There are two compaction components 300, and the outer frames 310 inside the two compaction components 300 are fitted together to form a ring; After the outer frames 310 inside the two compaction components 300 are attached to each other, they form a cylindrical shape that runs through their axis. The two pressure plates 320 inside the two compaction components 300 are fitted together to form a ring; The telescopic rod 330 extends and retracts, causing the pressure plate 320 to tilt downwards and press down on the sand around the sapling; After the pressure plates 320 inside the two compaction components 300 are attached to each other and pressed down on the sand around the sapling, the sand around the sapling forms a frustum shape.

[0025] Specifically, first adjust the positions of the two compaction components 300 so that they are symmetrically placed on both sides of the sapling, and make the outer frames 310 inside the two compaction components 300 fit together, and the two pressing plates 320 inside the two compaction components 300 fit together to form a ring, completely wrapping the sapling; then, by repeatedly extending and retracting the telescopic rod 330, the pressing plates 320 are tilted towards the sand around the sapling to press it down. Because the telescopic rod 330 is inclined, when the telescopic rod 330 drives the pressure plate 320 to extend and retract, it can gather the sand around the seedling towards the center, making it easy to pile up a truncated cone-shaped mound of soil around the seedling to support and fix its position. In areas with frequent wind and sand activity, the truncated cone-shaped mound of soil can play a certain role in preventing wind and sand, reducing the direct erosion of the seedling's root collar by wind speed, and fixing the sand around the roots to prevent the seedling from being blown over by the wind or its roots from being exposed. The sloping structure of the truncated cone shape can effectively collect smaller amounts of rainwater, dew, or snowmelt into the planting hole at the base of the seedling, increasing the water supply to the root area.

[0026] Furthermore, during the pressing process, the electric slide table 340 can drive the pressure plate 320 to perform a small-amplitude rotation operation to perform a micro-leveling operation on the soil pile. When there is more sand on one side of the sapling and less sand on the other side, after the outer frames 310 of the two compaction components 300 are attached to each other, the two pressure plates 320 are not attached to each other and a distance is left between them. By rotating the pressure plates 320, the soil pile is pushed and dispersed so that it can be evenly distributed on all four sides of the sapling. Then the normal pressing operation is carried out.

[0027] With the pressure plate 320 pressed tightly against the sandy soil around the sapling, the axis of the pressure plate 320 and the axis of the outer frame 310 are on the same straight line. When the telescopic rod 330 drives the pressure plate 320 to move up and down, the axis of the pressure plate 320 is parallel to the axis of the outer frame 310. The electric slide 340 is used to drive the telescopic rod 330 and the pressure plate 320 to rotate in an arc, leveling the sand around the seedling.

[0028] When the electric slide table 340 drives the pressure plate 320 to rotate in an arc, the rotation axis of the pressure plate 320 and the axis of the outer frame 310 are on the same straight line. When the telescopic rod 330 is at the center of the electric slide table 340, the electric slide table 340 drives the pressure plate 320 to rotate clockwise and counterclockwise by an angle of 0 to 30 degrees.

[0029] There are two robotic arms 200, and each robotic arm 200 corresponds to one of the two compaction components 300. Two robotic arms 200 are symmetrically fixed on the traveling vehicle 100; The 100-type vehicle is a tracked vehicle; The compaction component 300 is fixed to the output end of the robotic arm 200, and the outer ring of the outer frame 310 is fixed to the output end of the robotic arm 200. Both the traveling vehicle 100 and the robotic arm 200 are used to adjust the pressing position of the compaction component 300.

[0030] An observation port 311 is provided on the side of the outer frame 310, and the observation port 311 is set through the outer frame 310. The electric slide 340 is located above the observation port 311.

[0031] Specifically, the device adjusts its position using a walking vehicle 100, which is a tracked vehicle that can move and operate normally in the sand. The position of the compaction component 300 is adjusted by the robotic arm 200 to compact the sand around multiple seedlings. Furthermore, during the pressing process, observation can be performed through the top of the outer frame 310 and the observation port 311.

[0032] The walking vehicle 100, robotic arm 200, telescopic pole 330 and electric slide 340 are all existing technologies and will not be described in detail here.

[0033] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: The inclined telescopic rod 330 drives the arc-shaped pressure plate 320 to press down, which not only compacts the sand but also effectively gathers the sand around the seedling towards the center. This solves the problem of traditional up-and-down pressing causing the sand to disperse in all directions and have poor central gathering effect. It can also prevent wind and sand, protecting the seedling roots. Its inclined structure is conducive to collecting rainwater and dew to the seedling roots, improving water utilization. The pressure plate 320 can be rotated slightly by the electric slide table 340, which can micro-level the surface of the soil mound, making the surface smooth and beautiful and with better water retention, and can also adjust the even distribution of sand around the seedling.

[0034] Example 2: During use, the above-mentioned device presses the sand by moving the pressure plate 320 up and down. During operation, the pressing generates vibrations, and the rotation causes the sand to shift, resulting in the saplings shaking and tilting. Furthermore, the pressing process generates a large amount of dust, causing serious air pollution. If the saplings are planted but the surrounding sand is not compacted, they may be blown away by the wind and tilt. Therefore, improvements are made to the solution in Example 1, such as... Figures 2-8 As shown: The compaction assembly 300 also includes a tension membrane 350 and an exhaust net 360; Both the stretch membrane 350 and the exhaust net 360 are arc-shaped. The lower end of the stretch membrane 350 is fixed to the inner wall of the outer frame 310, the lower end of the exhaust net 360 is fixed to the upper end of the stretch membrane 350, and the upper end of the exhaust net 360 is fixed to the outer wall of the pressure plate 320.

[0035] It also includes bonding components 400, of which there are two, and the two bonding components 400 correspond one-to-one with the two compaction components 300; The bonding assembly 400 includes a mounting plate 410, a second tension membrane 420, a second exhaust mesh 430, a fixing rod 440, a positioning plate 450, and a fixing bladder 460; The mounting plate 410 is arc-shaped and is fixed to the upper side of the pressure plate 320. The mounting plate 410 is located at the arc-shaped opening of the pressure plate 320. The lower end of the second tension membrane 420 is fixed to the upper side of the mounting plate 410, and the lower end of the second exhaust net 430 is fixed to the upper end of the second tension membrane 420. The positioning plate 450 is a cylindrical shape that runs through its axis, and the upper end of the exhaust net 430 is fixed to the lower side of the positioning plate 450. There are two fixing rods 440, which are symmetrically fixed on both sides of the positioning plate 450. The end of the fixing rod 440 away from the positioning plate 450 is fixed to the inner wall of the outer frame 310. Both exhaust mesh 1 (360°) and exhaust mesh 2 (430°) are made of non-woven fabric. Both the 350 tension membrane and the 420 tension membrane are made of rubber. Specifically, by pulling the membrane 350, the exhaust net 360, the membrane 420, and the exhaust net 430 up and down pressing the sand on the pressure plate 320, the four sides of the sapling are intercepted and covered. As the pressure plate 320 tilts downward, the excess gas inside is discharged through the exhaust net 360 and the exhaust net 430. Since the exhaust net 360 and the exhaust net 430 are both made of non-woven fabric, they can also intercept smoke and dust while venting. When the pressure plate 320 rotates, since both the first tension membrane 350 and the second tension membrane 420 are made of rubber, they can withstand a certain degree of deformation and adapt to the rotation of the pressure plate 320. After the pressure plate 320 is reset, the first tension membrane 350 and the second tension membrane 420 can return to their normal state.

[0036] Since the positioning plate 450 is fixed in position by the fixing rod 440, when the pressure plate 320 tilts and moves to press, only the mounting plate 410 will move, and the resulting tension will cause the tension membrane 350, the exhaust net 360, the tension membrane 420 and the exhaust net 430 to deform.

[0037] The fixation bladder 460 is fixed to the inner ring of the positioning plate 450.

[0038] Specifically, when the two compaction components 300 approach each other, the sapling is first positioned between the two fixing pockets 460. After the two compaction components 300 are fully attached, the sapling is positioned within the two positioning plates 450. The fixing pockets 460 completely enclose the sapling, and the position of the sapling is restricted by the fixing pockets 460. During the pressing and rotating of the sand by the pressing plate 320, the position of the sapling will not move and will always remain vertical.

[0039] When dealing with saplings that have been blown down or tilted by the wind, the position of the sapling can be adjusted by the clamping and moving of the fixing bag 460, which helps to keep the sapling upright and compact the surrounding sand. Furthermore, by attaching the fixing bag 460 to the sapling, the positioning plate 450 is sealed to prevent the generated smoke and dust from escaping from above.

[0040] The lower end of the stretch membrane 350 is fixed below the observation port 311; When the two pressure plates 320 inside the two compaction components 300 are pressed together, the two tension films 350 can be pressed together to form a ring. When the two pressure plates 320 inside the two compaction components 300 are in contact with each other, the two exhaust nets 360 can be in contact with each other to form a ring. When the two pressure plates 320 in the two compaction components 300 are in contact with each other, the two mounting plates 410 can be in contact with each other to form a hollow frustum shape along its axis, and the axis of the mounting plate 410 and the axis of the pressure plate 320 are on the same straight line. When the two pressure plates 320 inside the two compaction components 300 are pressed together, the two tension membranes 420 can be pressed together to form a ring. When the two pressure plates 320 inside the two compaction components 300 are in contact with each other, the two exhaust nets 430 can be in contact with each other to form a ring. When the two pressure plates 320 inside the two compaction components 300 are in contact with each other, the two positioning plates 450 can be in contact with each other to form a hollow cylinder along its axis. When the two positioning plates 450 within the two fitting components 400 are fitted together, the two fixing bladders 460 are fitted together. The positioning plate 450 axis and the outer frame 310 axis are on the same straight line.

[0041] Specifically, when the two pressure plates 320 within the two compaction components 300 are in contact with each other, the two tension membranes 350, the two exhaust nets 360, the two mounting plates 410, the two tension membranes 420, the two exhaust nets 430, and the two positioning plates 450 can be in contact with each other to intercept the generated smoke and dust.

[0042] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: Between the pressure plate 320 and the outer frame 310, a tension membrane 350, an exhaust net 360, a tension membrane 420, and an exhaust net 430 are installed to form a retractable sealed cavity. When the pressure plate 320 moves up and down to compact the sand, the internal air can be discharged through the exhaust net 360 and the exhaust net 430, but the smoke and dust are effectively intercepted to prevent them from escaping into the air and causing secondary pollution. When the two compaction components 300 are closed, the internal fixing bladders 460 can fit together and tightly wrap the trunk and sapling of the tree. When the pressure plate 320 compacts and rotates the sand, it can firmly fix the sapling, prevent it from shaking, tilting or falling over, and ensure the quality of tree planting.

[0043] Example 3: The above solution cannot adapt to pressing soil mounds of any size during use; as the pressing plate 320 tilts and descends, sand will protrude from the arc-shaped opening of the pressing plate 320, causing the sand to protrude between the two mounting plates 410. The sand between the two mounting plates 410 cannot be pressed, resulting in a loose contact between the sapling and the sand; furthermore, when there are gravel pieces in the sand, the rigid pressing plate 320 may forcefully press down on the stones, damaging the underlying root system; therefore, the solution in Example 2 is improved, such as... Figure 3 , Figure 4, Figure 7 As shown: It also includes auxiliary components 500, of which there are two, and each of the two auxiliary components 500 corresponds one-to-one with a compaction component 300; The auxiliary component 500 includes an airbag 510, an air pump 520, an airbag 530, and an air pump 540. Airbag 510 is arc-shaped and is fixed below pressure plate 320. Airbag 510 is fixed on the inclined side of the cross section of pressure plate 320. Air pump 520 is fixed on pressure plate 320, and the output end of air pump 520 is connected to airbag 510.

[0044] Specifically, when pressing and piling up sand and soil in a small area into a frustum shape, the airbag 510 expands inward to press the soil pile, adapting to soil piles of any size for pressing operations.

[0045] Airbag 2 530 is arc-shaped and is fixed to the inner ring of mounting plate 410. Air pump 2 540 is fixed to the outer ring of mounting plate 410 and the output end of air pump 2 540 is connected to airbag 2 530.

[0046] Specifically, the expansion of the airbag 530 allows it to fit snugly against the sapling, preventing damage to the sapling even as the pressing plate 320 moves up and down to press the sand. During the up-and-down movement of the pressing plate 320, the airbag 530 presses the sand around the sapling.

[0047] By controlling the inflation pressure of airbag 510 and airbag 530, the compaction degree of different locations on the soil pile can be finely adjusted.

[0048] Airbag 1 510 and Airbag 2 530 can avoid pressing down hard on rocks in sandy areas.

[0049] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: When dealing with small areas of sand or needing to shape truncated cones of specific sizes, airbag 510 can be inflated to increase the effective area and pressure of the compaction surface, flexibly adapting to the compaction needs of different sized mounds and improving the equipment's versatility. Airbag 530 is installed inside the mounting plate 410 at the arc-shaped opening above the pressure plate 320. Airbag 530 gently conforms to the seedling, preventing direct collision damage from mechanical parts. Airbag 530 further compacts the sand at the arc-shaped opening of the pressure plate 320, ensuring that the sand around the seedling's roots is compacted, making the seedling more firmly and reliably fixed. By controlling the inflation pressure of airbags 510 and 530, the compaction degree at different locations of the mound can be fine-tuned. When encountering small, hard objects or stones, airbags 510 and 530 deform, distributing the pressure more evenly across the surrounding sand, preventing shearing or crushing damage to the seedling roots.
