Description

Technical Field

[0001] This invention relates to the field of transplanting machinery technology, and in particular to a transplanting device that can automatically control the transplanting depth. Background Technology

[0002] Transplanting, also known as transplanting, refers to the process of uprooting or digging up seedlings sown in seedbeds or paddy fields and planting them in the field. This process is commonly used in agriculture and horticulture to move seedlings from one environment to another to promote their growth and development. In the process of transplanting, especially in the transplanting of trees, it is necessary to first dig at the transplanting site, then place the seedling in a deep pit, and then fill it in to complete the overall transplanting operation. The overall operation is simple.

[0003] However, in actual transplanting, the transplanting depth mainly depends on the height of the excavated pit and cannot be adjusted according to the actual working conditions. After the tree is placed in the pit, multiple people need to work together. This involves staff determining the tree's position to reduce the possibility of it tilting, and quickly filling the pit with soil. The overall work is quite cumbersome. During the filling process, attention must be paid to the weight of the soil each time. If the weight of the soil is too large, it may damage the tree when it comes into contact with the soil, affecting its normal growth. At the same time, during the filling process, manual trampling is required to improve the stability between the sapling and the soil after filling. This is time-consuming, labor-intensive, and involves a large workload. Therefore, a transplanting device that can automatically control the transplanting depth is needed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a transplanting device that can automatically control the transplanting depth.

[0005] The present invention adopts the following technical solution:

[0006] A transplanting device capable of automatically controlling transplanting depth includes a fixing plate, a hook lock installed on the front side of the fixing plate, a first hydraulic rod fixedly connected to the lower side of the fixing plate, a ball ring fixedly connected to the output end of the first hydraulic rod, a limit component installed inside the ball ring, the limit component including two sliding grooves opened inside the ball ring, a sliding plate slidably connected in the two sliding grooves, a first spring fixedly connected between the sliding plate and the sliding groove, an arc-shaped plate fixedly connected to the side of the sliding plate away from the sliding groove, multiple triangular plates fixedly connected to both sides of the sliding plate, two locking blocks slidably connected to the side wall of the sliding groove, a second hydraulic rod fixedly connected inside the ball ring, a connecting ring fixedly connected to the output end of the second hydraulic rod, multiple baffles slidably connected to the side wall of the connecting ring, and a control component for releasing the limit component installed inside the ball ring.

[0007] Preferably, the control component includes a motor fixedly installed inside a ball ring; multiple square rods are circumferentially rotatably connected to the upper side of the connecting ring; second gears are fixedly connected to the outer sides of the multiple square rods; multiple second racks are slidably connected to the sidewall of the connecting ring; the second racks mesh with the second gears; each second rack is fixedly connected to a baffle; a third spring is fixedly connected between the baffle and the connecting ring; multiple transmission rods are rotatably installed inside the ball ring; one of the transmission rods is fixedly connected to the output end of the motor; a third gear is fixedly connected to the outer side of each transmission rod; adjacent third gears mesh with each other; a deep groove is formed on the lower side of each transmission rod, the deep groove being opposite to the square rod; two fourth connecting plates are fixedly connected inside the connecting ring; a fourth connecting rod is fixedly connected to the upper side of the two fourth connecting plates; a first connecting plate is fixedly connected to the upper side of the fourth connecting rod; one end of the first connecting plate extends into a sliding groove; and the first connecting plate is fixedly connected to a locking block.

[0008] Preferably, a compaction assembly is installed on the outer side of the ball ring. The compaction assembly includes multiple reciprocating screws rotatably installed inside the ball ring. The position and number of the multiple reciprocating screws are opposite to the transmission rod. Each reciprocating screw is connected to the transmission rod via a pulley assembly. A movable plate is threaded onto the outer side of each reciprocating screw. The movable plate is slidably connected to the ball ring. A second connecting plate is fixedly connected to the lower side of the movable plate. A second connecting rod is sleeved inside the second connecting plate. Both ends of the second connecting rod are fixedly connected to cylinders. A first gear is fixedly connected to the outer side of the second connecting rod. A first rack is fixedly connected inside the second connecting plate. The first rack and the first gear mesh. Two collars are rotatably sleeved on the outer side of the second connecting rod. A fourth spring is fixedly connected between the two collars and the movable plate.

[0009] Preferably, an auxiliary landfill assembly is installed inside the cylinder. The auxiliary landfill assembly includes a frustum slidably installed inside the cylinder. A second spring is fixedly connected between the frustum and the cylinder. Multiple inclined grooves are evenly opened circumferentially on the side wall of the frustum. A sliding rod is slidably connected in each inclined groove. A third connecting plate is fixedly connected to the outside of the sliding rod. The third connecting plate is slidably connected to the cylinder. Two third connecting rods are fixedly connected to the outside of the frustum. Both third connecting rods slide through the cylinder. A ring is fixedly connected to the side of the two third connecting rods away from the cylinder. Two round rods are symmetrically fixedly connected to the outside of the second connecting plate. Two contact switches are also fixedly connected to the outside of the second connecting plate.

[0010] Preferably, both the inner wall of the ring and the outer side of the rod are smooth.

[0011] Preferably, the baffle is fixedly fitted with a rubber pad.

[0012] Preferably, a plurality of brackets are fixedly installed on the lower side of the fixing plate, and omnidirectional wheels are fixedly installed on the lower side of the plurality of brackets.

[0013] The beneficial effects of this invention are:

[0014] 1. First, during the transplanting process, the tree to be transplanted is placed inside the ball ring, and then the device is pushed to the upper side of the pit. The position of the transplanted tree in the pit is adjusted by the first hydraulic rod until the position of the transplanted tree in the pit meets the working requirements, thereby completing the control operation of the transplanting depth.

[0015] 2. Secondly, during the transplanting process, especially when filling the deep pit with soil manually, when the soil in the deep pit moves to the bottom of the cylinder, the cylinder and the soil come into contact, which will cause the soil to be squeezed and knocked, reducing the amount of work that workers need to do by stepping on the soil.

[0016] 3. Furthermore, when the cylinder and the soil come into contact, the third connecting plate will extend out from inside the cylinder. When the cylinder rotates, the cylinder will drive the third connecting plate to rotate. The third connecting plate will come into contact with the soil pressed on the underside of the cylinder, thereby causing the soil on the underside to move towards the trees, which can further reduce the workload of workers.

[0017] 4. Then, when all the cylinders and the contact switch are in contact, it indicates that there is a lot of soil on the underside of all the cylinders. At this time, the first hydraulic rod is activated to move the ball ring upward until there is a large gap between the cylinder and the soil. The soil filling operation is carried out again until all the cylinders are in contact with the soil again. The above operation is repeated until the soil filling meets the work requirements. The degree of automation and intelligence is high. Attached Figure Description

[0032] See Figures 1-13 A transplanting device capable of automatically controlling transplanting depth includes a fixing plate 1. A hook lock 5 is installed on the front side of the fixing plate 1. A first hydraulic rod 4 is fixedly connected to the lower side of the fixing plate 1. A ball ring 7 is fixedly connected to the output end of the first hydraulic rod 4. A limit component is installed inside the ball ring 7. The limit component includes two sliding grooves 10 opened inside the ball ring 7. A sliding plate 11 is slidably connected to the two sliding grooves 10. A first spring 13 is fixedly connected between the sliding plate 11 and the sliding grooves 10. An arc-shaped plate 12 is fixedly connected to the side of the sliding plate 11 away from the sliding grooves 10. Both sides of the sliding plate 11 are fixedly connected to... There are multiple triangular plates 14, two locking blocks 15 are slidably connected to the side wall of the slide groove 10, a second hydraulic rod 43 is fixedly connected inside the ball ring 7, a connecting ring 34 is fixedly connected to the output end of the second hydraulic rod 43, multiple baffles 20 are slidably connected to the side wall of the connecting ring 34, a control component for releasing the limit component is installed inside the ball ring 7, multiple brackets 2 are fixedly installed on the lower side of the fixed plate 1, universal wheels 3 are fixedly installed on the lower side of the multiple brackets 2, and rubber pads are fixedly fitted to the baffles 20 to improve the friction of the baffles 20, thereby enabling better placement of trees;

[0033] First, during transplanting, the device can be installed at the end of a power device (such as a tractor) using the hook lock 5. The power device can then be used to move the entire device. Second, in the initial state, the distance between the multiple baffles 20 is small. Third, when transplanting is required, the control component moves the locking block 15 upward, disconnecting the connection between the locking block 15 and the triangular plate 14, thus removing the restriction between the triangular plate 14 and the sliding plate 11. The tree to be transplanted is placed on the upper side of the baffle 20. At this time, under the action of the first spring 13, the arc plate 12 abuts against the tree. Then, the control component again locks the sliding plate 11 to push the entire device, aligning the tree to be transplanted with the dug pit. At this time, the caster wheel 3 is locked, and then the first hydraulic rod 4 is activated. The first hydraulic rod 4 moves the ball ring 7 downward, which in turn moves the tree downward, moving the tree to be transplanted into the pit until the position of the transplanted tree in the pit meets the working requirements. Then, the first hydraulic rod 4 is closed, filler soil is added to the pit, and the transplanting operation begins.

[0034] like Figure 6 , Figure 12The control assembly includes a motor 16 fixedly installed inside a ball ring 7. Multiple square rods 39 are rotatably connected to the upper side of a connecting ring 34. Second gears 40 are fixedly connected to the outer sides of the square rods 39. Multiple second racks 41 are slidably connected to the sidewalls of the connecting ring 34, meshing with the second gears 40. Each second rack 41 is fixedly connected to a baffle 20. A third spring 42 is fixedly connected between the baffle 20 and the connecting ring 34. Multiple transmission rods 17 are rotatably installed inside the ball ring 7, one of which is connected to the motor 16. The output end of 6 is fixedly connected. A third gear 44 is fixedly connected to the outside of each transmission rod 17. Two adjacent third gears 44 mesh with each other. A deep groove 6 is opened on the lower side of each transmission rod 17. The deep groove 6 is opposite to the square rod 39. Two fourth connecting plates 35 are fixedly connected inside the connecting ring 34. A fourth connecting rod 36 is fixedly connected to the upper side of the two fourth connecting plates 35. A first connecting plate 37 is fixedly connected to the upper side of the fourth connecting rod 36. One end of the first connecting plate 37 extends into the slide groove 10. The first connecting plate 38 is fixedly connected to the locking block 15.

[0035] First, both the deep groove 6 and the square rod 39 are regular polygons. Second, the number of second gears 40 is twice the number of second racks 41. The connection between the second racks 41 and the second gears 40 is as follows: Figure 12As shown, during the soil backfilling process, the backfilling is mainly divided into two parts. The first part is filling the pit after the location of the transplanted tree is determined, ensuring that the height inside the filled pit meets the work requirements, so that the tree placed in the filled pit is at a suitable transplanting depth. The second part is burying the roots of the transplanted tree after it is placed in the pit, completing the fixing operation of the transplanted tree. The above two work processes are carried out sequentially. First, the depth of the transplanted tree is confirmed, and then the pit is filled. At this time, motor 16 is started. 16 drives the transmission rod 17, which is fixedly connected to its output end, to rotate counterclockwise. The transmission rod 17 drives all transmission rods 17 to rotate through the third gear 44. Among them, the transmission rods 17 with baffles 20 on their lower side rotate counterclockwise, and the transmission rods 17 without baffles 20 on their lower side rotate clockwise. Therefore, it can be ensured that all second gears 40 meshing with the second rack 41 are rotating counterclockwise. Then, during the rotation of the transmission rod 17, when there is too much filling soil under the ball ring 7, that is, when the first part of the soil filling is just completed, The second hydraulic rod 43 will automatically activate (the structure and reason for the automatic activation of the second hydraulic rod 43 are explained below). The second hydraulic rod 43 drives the connecting ring 34 to move upward. The connecting ring 34 drives the square rod 39 to move upward and enter the deep groove 6 on the lower side of the transmission rod 17. The rotating transmission rod 17 will drive the square rod 39 to rotate. The square rod 39 drives the baffle 20 to move through the second gear 40 and the second rack 41, causing the baffle 20 to move away from the other side. The baffle 20 compresses the third spring 42 until the transplanted tree is no longer restricted by the baffle 20. At the same time, the connecting ring 34 will also drive the first connecting plate 37 to move upward through the fourth connecting plate 35 and the fourth connecting rod 36. The first connecting plate 37 will drive the locking block 15 to move upward through the first connecting rod 38. The locking block 15 and the triangular plate 14 will be disconnected, causing the sliding plate 11 to lose its restriction, thereby releasing the limiting component from the limiting operation of the transplanted tree, so that the tree can be transplanted into the deep pit. After the tree is moved into the filled deep pit, the first part of the soil filling operation has been completed, and the second part of the soil filling operation, that is, the root burying operation of the transplanted tree, will begin.

[0036] like Figure 6 , Figure 7 , Figure 8 , Figure 9A tamping assembly is installed on the outside of the ball ring 7. The tamping assembly includes multiple reciprocating screws 18 rotatably installed inside the ball ring 7. The position and number of the multiple reciprocating screws 18 are opposite to the transmission rod 17. Each reciprocating screw 18 is connected to the transmission rod 17 via a pulley assembly 19. A moving plate 8 is threadedly sleeved on the outside of each reciprocating screw 18. The moving plate 8 is slidably connected to the ball ring 7. A second connecting plate 21 is fixedly connected to the lower side of the moving plate 8. A second connecting rod 25 is sleeved inside the second connecting plate 21. Both ends of the second connecting rod 25 are fixedly connected to cylinders 9. A first gear 26 is fixedly connected to the outside of the second connecting rod 25. A first rack 27 is fixedly connected to the second connecting plate 21. The first rack 27 and the first gear 26 mesh with each other. Two collars 45 are rotatably sleeved on the outside of the second connecting rod 25. A fourth spring 46 is fixedly connected between the two collars 45 and the moving plate 21. The inner wall of the ring 30 and the outer side of the rod 24 are both smooth.

[0037] At the start of the first part of the soil filling, motor 16 is started. Motor 16 drives transmission rod 17, which is fixedly connected to its output end, to rotate counterclockwise. Transmission rod 17 drives reciprocating screw 18 to rotate via pulley assembly 19. Since reciprocating screw 18 is threadedly connected to moving plate 8, and moving plate 8 is slidably connected to ball ring 7, the rotating reciprocating screw 18 will drive moving plate 8 to move up and down. Moving plate 8 drives second connecting rod 25 to move up and down via second connecting plate 21 and fourth spring 46. Second connecting rod 25 drives cylinder 9 to move up and down. During the soil filling process, that is, when the first part of the soil filling is just completed, the depth of the soil in the pit moves to the bottom of cylinder 9. When the cylinder 9 comes into contact with the soil, it will compress and beat the soil, reducing the amount of work that workers need to do by stepping on the soil. When the cylinder 9 comes into contact with the soil, the resistance of the soil will cause the cylinder 9 to move upward relative to the moving plate 8, which will in turn cause the second connecting rod 25 to move upward relative to the moving plate 8. Under the action of the first rack 27 and the first gear 26, the cylinder 9 and the second connecting rod 25 will rotate as a whole, which can improve the compression and beating of the soil. Then, during the subsequent filling of the second part of the soil, the soil in the deep pit will come into contact with the cylinder 9 again, and the same work will happen, which can again compress and beat the soil.

[0038] like Figure 8 , Figure 10 , Figure 11An auxiliary landfill assembly is installed inside the cylinder 9. The auxiliary landfill assembly includes a frustum 28 slidably installed inside the cylinder 9. A second spring 29 is fixedly connected between the frustum 28 and the cylinder 9. Multiple inclined grooves 32 are evenly opened circumferentially on the side wall of the frustum 28. A slide rod 31 is slidably connected in each inclined groove 32. A third connecting plate 22 is fixedly connected to the outside of the slide rod 31. The third connecting plate 22 is slidably connected to the cylinder 9. Two third connecting rods 33 are fixedly connected to the outside of the frustum 28. Both third connecting rods 33 slide through the cylinder 9. A ring 30 is fixedly connected to the side of the two third connecting rods 33 away from the cylinder 9. Two round rods 24 are symmetrically fixedly connected to the outside of the second connecting plate 21. Two contact switches 23 are also fixedly connected to the outside of the second connecting plate 21. The inner wall of the ring 30 and the outer side of the round rods 24 are smooth.

[0039] First, the contact switch 23 on the outside of the second connecting plate 21 is electrically connected to the control circuit of the second hydraulic rod 43, and the multiple contact switches 23 are in series. That is, when all contact switches 23 are activated, the second hydraulic rod 43 will automatically start. Second, in the initial state, the third connecting plate 22 is located inside the cylinder 9 and will not move out of the cylinder 9. Furthermore, the ring 30 is not in contact with the rod 24 or the contact switches 23. When the cylinder 9 is obstructed by the soil, the ring 30 will move upward relative to the second connecting plate 21. Figure 10 As can be seen, the inner ring of the ring 30 has a chamfer. That is, when the inner wall of the ring 30 abuts against the rod 24, the rod 24 will cause the ring 30 to move relative to the cylinder 9. Figure 11Based on the direction, the left ring 30 moves to the left and the right ring 30 moves to the right. Taking the right ring 30 as the basis for analysis, the right ring 30 drives the frustum 28 to move to the right through the third connecting rod 33. The frustum 28 compresses the second spring 29. Since the third connecting plate 22 and the cylinder 9 are slidably connected, under the action of the inclined groove 32 and the sliding rod 31, the third connecting plate 22 will move away from the cylinder 9 relative to the cylinder 9. The third connecting plate 22 extends out from inside the cylinder 9. When the cylinder 9 rotates, the cylinder 9 drives the third connecting plate 22 to rotate. The third connecting plate 22 abuts against the soil pressed on the lower side of the cylinder 9, thereby causing the soil on the lower side to move towards the trees, which can further reduce the workload of workers. In the process of the cylinder 9 moving upward relative to the moving plate 8, when all the rings 30 abut against the contact switch 23, it indicates that there is a lot of soil on the lower side of all the cylinders 9. When the first part of the soil filling is just completed, the second hydraulic rod 43 is activated until the transplanted trees are no longer restricted by the baffle 20. At this point, the first hydraulic rod 4 is activated, causing the ball ring 7 to move upward until there is a large gap between the cylinder 9 and the soil. At this point, the cylinder 9 is no longer restricted by the soil, which causes the ring 30 to disconnect from the contact switch 23. The second hydraulic rod 43 is then closed again, causing it to move the connecting ring 34 downward, returning the connecting ring 34 to its original position relative to the ball ring 7. At this point, the square rod 39 and the transmission rod 17 are disconnected, the baffle 20 comes into contact with the trees, and the sliding plate 11 is locked again. The second part of the soil filling begins. During the second part of the soil filling, when all the cylinders 9 come into contact with the soil again, the first hydraulic rod 4 is activated again, and the above operation is repeated until the soil filling meets the work requirements. At this point, the second part of the soil filling is also completely completed.

[0040] In this invention, when transplanting is required, the second hydraulic rod 43 is activated first, causing the connecting ring 34 to move upward. The connecting ring 34 drives the first connecting plate 37 to move upward via the fourth connecting plate 35 and the fourth connecting rod 36. The first connecting plate 37 drives the locking block 15 to move upward via the first connecting rod 38, causing the locking block 15 and the triangular plate 14 to be misaligned and the arc plate 12 to move away from each other. The arc plate 12 drives the sliding plate 11 to move, and the sliding plate 11 compresses the first spring 13. At this time, the tree to be transplanted is placed on the upper side of the multiple baffles 20. Then, the arc plate 12 is released. Under the action of the first spring 13, the arc plate 12 and the tree abut against each other. The second hydraulic rod 43 is activated again, causing the connecting ring 34 to return to its original position relative to the ball ring 7. At this time, the locking block 15 and the triangular plate 14 abut against each other again, locking the sliding plate 11, thereby completing the positioning operation of the tree.

[0041] Push the entire device so that the tree to be transplanted is aligned with the dug pit. At this time, lock the caster wheel 3, then activate the first hydraulic rod 4. The first hydraulic rod 4 drives the ball ring 7 to move downward, and the ball ring 7 drives the tree downward, so that the tree to be transplanted is moved into the pit until the position of the transplanted tree in the pit meets the working requirements. Then close the first hydraulic rod 4, thus completing the operation of fixing the position of the transplanted tree.

[0042] After the location of the transplanted tree is fixed, soil is added to the pit. The soil filling process consists of two main parts: first, filling the pit to ensure the pit's depth meets the work requirements, allowing the tree to be placed at the appropriate transplanting depth; second, burying the roots of the transplanted tree after it has been placed in the pit, thus securing the tree. These two processes are performed sequentially.

[0043] During the first phase, motor 16 is started, driving transmission rod 17, which is fixedly connected to its output end, to rotate counterclockwise. Transmission rod 17, via third gear 44, drives all transmission rods 17 to rotate. Transmission rods 17 with baffles 20 on their lower sides rotate counterclockwise, while those without baffles 20 rotate clockwise. During this rotation, transmission rod 17 drives reciprocating screw 18 via pulley assembly 19. Since reciprocating screw 18 is threadedly connected to moving plate 8, and moving plate 8 is slidably connected to ball ring 7, the rotating reciprocating screw 18 drives moving plate 8 up and down. Moving plate 8, via second connecting plate 21 and fourth spring, drives second connecting rod 25 up and down. Second connecting rod 25 drives cylinder 9 up and down. During the backfilling process, when the soil in the pit moves to the lower side of cylinder 9, cylinder 9 comes into contact with the soil, causing compression and impact. The operation reduces the amount of work that workers need to do by trampling on the soil. When the cylinder 9 comes into contact with the soil, the resistance of the soil causes the cylinder 9 to move upward relative to the moving plate 8, which in turn causes the second connecting rod 25 to move upward relative to the moving plate 8. Under the action of the first rack 27 and the first gear 26, the cylinder 9 and the second connecting rod 25 will rotate as a whole, which can improve the squeezing and hammering of the soil. When the cylinder 9 stops moving due to the resistance of the soil, the ring 30 will move relative to the cylinder 9. Under the action of the inclined groove 32 and the sliding rod 31, the third connecting plate 22 will move away from the cylinder 9. The third connecting plate 22 extends out from the inside of the cylinder 9. When the cylinder 9 rotates, the cylinder 9 drives the third connecting plate 22 to rotate. The third connecting plate 22 comes into contact with the soil pressed on the lower side of the cylinder 9, which in turn moves the soil on the lower side and smooths the soil, which can further reduce the workload of workers.

[0044] During the above process, the transplanted tree is always located above the baffle 20, and the buried soil does not come into contact with the tree. As more and more soil is added, the bottom of the pit gradually rises. When all the rings 30 are in contact with the contact switch 23, it indicates that the height inside the pit is relative to the transplanting depth. At this time, the second hydraulic rod 43 is activated, which drives the connecting ring 34 to move upward. The connecting ring 34 drives the square rod 39 to move upward and enter the deep groove 6 below the transmission rod 17. At this time, the rotating transmission rod 17 drives the square rod 39 to rotate. The square rod 39 drives the baffle 20 to move through the second gear 40 and the second rack 41, causing the baffle 20 to move away from the other side. The baffle 20 compresses the third spring 42 until the transplanted tree is no longer restricted by the baffle 20. At the same time, the connecting ring 34 will also move through the fourth connecting plate 35 and the fourth connecting rod 3 6 drives the first connecting plate 37 to move upward. The first connecting plate 37 drives the locking block 15 to move upward through the first connecting rod 38. The locking block 15 and the triangular plate 14 are disconnected, causing the sliding plate 11 to lose its restraint. This allows the tree located on the upper side of the baffle 20 to fall to the bottom of the filled pit. At this time, the first hydraulic rod 4 can be manually activated to drive the ball ring 7 to move upward until there is a large gap between the cylinder 9 and the soil. At this time, the cylinder 9 loses the restraint of the soil, which causes the ring 30 to disconnect from the contact switch 23. The second hydraulic rod 43 is closed again, which causes the second hydraulic rod 43 to drive the connecting ring 34 to move downward, so that the connecting ring 34 returns to its original position relative to the ball ring 7. At this time, the square rod 39 and the transmission rod 17 are disconnected, the baffle 20 and the tree abut against each other, and the sliding plate 11 is locked again, which restricts the tree again, thus completing the filling of the pit and the placement of the transplanted tree.

[0045] Continue filling the soil. During this process, the second part of the work begins, which is the process of burying the roots of the transplanted trees. When all the cylinders 9 are in contact with the soil again, the second hydraulic rod 43 is automatically activated again, causing the locking block 15 and the triangular plate 14 to disconnect, and the sliding plate 11 to lose its restraint. At this time, the first hydraulic rod 4 can be activated again, causing the ball ring 7 to move upward a certain distance until there is a large gap between the cylinders 9 and the soil. This process is repeated until the soil filling in the pit meets the work requirements. During the above work, the control system of the first hydraulic rod 4 can be adjusted so that the distance the first hydraulic rod 4 moves upward with the ball ring 7 is equal each time it is manually activated. This results in layered filling during the soil filling process, and the soil is compacted each time it is filled, which can greatly improve the soil compaction effect and improve the transplanting quality.
