Description

Technical Field

[0001] This application relates to the field of turf transplantation technology in high-altitude areas, and in particular to a soil preparation device for turf transplantation in high-altitude areas. Background Technology

[0002] Currently, many environmental protection engineering methods and technologies have been adopted for the maintenance, transplantation, and restoration of vegetation in high-altitude and cold environments to better protect the ecological environment. For the purpose of protecting vegetation, construction currently mainly adopts the following method: before construction, the turf near the construction site is transplanted; after construction is completed, the transplanted turf is then laid back on the original planting site, thereby protecting the vegetation in the original planting area and preventing the vegetation from being affected by construction.

[0003] Currently, before re-laying transplanted turf, the soil at the turf re-laying site is usually loosened and prepared to facilitate the growth of the transplanted turf. In actual operation, for high-altitude areas above 3800 meters, large machinery such as soil loosening machines are difficult to access the work site. Therefore, manual soil loosening is often the only option, where operators use hand tools to turn the soil. This manual operation is physically demanding and has low efficiency. Summary of the Invention

[0004] In order to improve the problems existing in the above-mentioned technology, this application provides a soil preparation device for high-altitude turf transplantation.

[0005] The soil preparation device for high-altitude turf transplantation provided in this application adopts the following technical solution: A soil preparation device for high-altitude turf transplantation includes a support base, a first driving member on the support base, a soil loosening seat detachably connected to the first driving member, the first driving member driving the soil loosening seat to move along the length direction of the support base; a soil loosening roller is rotatably connected to the soil loosening seat, a second driving member is provided on the soil loosening seat to drive the soil loosening roller to rotate, and soil loosening blades are provided on the soil loosening roller along the circumferential and axial directions.

[0006] By adopting the above technical solution, when it is necessary to loosen and prepare the soil on the turf back-laying base surface, the support base is installed on the base surface, and the loosening base is connected to the first driving component, so that the loosening base is located above the base surface; then the first driving component drives the loosening base to move along the length direction of the support base, and the movement of the loosening base drives the loosening roller to move. At the same time, the second driving component drives the loosening roller to rotate, and the loosening roller thereby drives the loosening blade to rotate while moving. The loosening blade thereby turns over the soil on the base surface to complete the loosening of the base surface.

[0007] Because the loosening seat and the first drive component are detachably connected, the loosening seat and the support seat can be separated when the device is transported and placed, thereby reducing the overall space required by the device so that the device can be transported to the work site. During the process of loosening the soil on the base surface using the device, there is no need for manual hand tools to turn the soil, thereby improving the loosening efficiency and reducing the intensity of manual operation.

[0008] Optionally, the soil loosening blade includes a fixed part disposed on the soil loosening roller, and a movable part is hinged to the end of the fixed part away from the soil loosening roller. The end of the movable part away from the hinge axis is sharp-edged, and a placement groove is provided on the fixed part for the movable part to be rotatably inserted.

[0009] By adopting the above technical solution, the loosening blade is composed of a fixed part and a movable part. The outer end of the movable part is sharp, which allows the movable part to better turn over the soil for loosening when the loosening blade rotates with the loosening roller. However, when transporting and placing it, the outer end of the movable part is exposed and is easily touched by the operator, thus causing injury. Therefore, a placement groove is opened on the fixed part. When using the device for loosening and sorting operations, the movable part is turned out so that the outer end of the movable part can contact the soil. After the device is used, the movable part is rotated in the direction close to the fixed part, so that the movable part is rotated into the placement groove, thereby avoiding the outer end of the movable part being exposed.

[0010] Optionally, the groove opening of the placement slot is provided with two opposing cleaning seats, which can respectively fit against the two sides of the movable part, and a channel is formed between the two cleaning seats for the movable part to rotate and be inserted into the placement slot.

[0011] By adopting the above technical solution, after the device is used up, the movable part is rotated in the direction close to the fixed part. During the process of the movable part rotating into the placement groove, the two sides of the movable part will fit against the cleaning seat. As the movable part rotates, the two cleaning seats will clean the two sides of the movable part to prevent soil from adhering to the movable part and entering the placement groove with the movable part. After the soil enters the placement groove and dries, it will be difficult for the movable part to rotate out.

[0012] Optionally, a damper is provided at the hinge shaft of the movable part, and a limiting plate is provided on the fixed part to limit the rotation range of the movable part.

[0013] By adopting the above technical solution, the damper is set at the hinge shaft of the movable part to improve the stability of the movable part during rotation. When the movable part rotates away from the fixed plate to abut against the limit plate, the continued rotation of the movable part in the same direction is restricted, thereby improving the stability of the movable part during the rotation of the loosening roller and preventing the movable part from rotating in the direction closer to the fixed part due to external resistance.

[0014] Optionally, the loosening roller has a receiving cavity, and the second driving component includes a first motor disposed in the receiving cavity. A driving rod is disposed on the output shaft of the first motor, and the end of the driving rod away from the first motor is connected to the inner wall of the loosening roller.

[0015] By adopting the above technical solution, the first motor operates to drive the output shaft to rotate, which in turn drives the drive rod to rotate. The rotation of the drive rod drives the loosening roller to rotate, which in turn drives the loosening blade to rotate to loosen the soil. Since the first motor is located inside the receiving cavity, the loosening roller can protect the first motor during its operation, preventing the first motor from being directly exposed to the outside and from being splashed by soil when it is turned over, thus avoiding damage to the first motor. In addition, the way the first motor is located inside the receiving cavity can further reduce the size of the device, making the overall structure of the device more compact and more conducive to the transportation and placement of the entire device.

[0016] Optionally, the loosening seat is provided with a leveling plate on the rear side along the moving direction, and the bottom of the leveling plate is provided with multiple leveling teeth.

[0017] By adopting the above technical solution, when the first driving component moves the loosening seat, the loosening seat moves the flat plate, and the flat plate moves multiple leveling teeth synchronously. The leveling teeth tidy up the base surface after it has been turned over and loosened by the loosening blade, so as to ensure the flatness of the base surface, thereby facilitating the subsequent re-laying of transplanted turf and ensuring the flatness of the transplanted turf re-laid into the base surface.

[0018] Optionally, the first driving component is provided with a plug rod, and the loosening seat is provided with a slot for inserting the plug rod, and an anti-slip pad is provided in the slot.

[0019] By adopting the above technical solution, when installing the soil loosening seat, the insertion rod is inserted into the slot, thereby connecting the soil loosening seat and the first driving component. The connection method is simple and easy to operate. The anti-slip pad set in the slot is used to improve the stability of the insertion rod when it is in the slot, and to prevent the insertion rod from sliding unstablely in the slot, thereby improving the stability of the soil loosening seat when it moves.

[0020] Optionally, a positioning pin is inserted into the insertion rod, and the positioning pin is also inserted into the loosening base.

[0021] By adopting the above technical solution, after the insertion rod is inserted into the slot, the positioning pin is simultaneously inserted into the insertion rod and the loosening base to fix the insertion rod again, thereby improving the stability of the insertion rod when it is in the slot.

[0022] Optionally, the support base includes a support portion and a sliding portion, the first driving member is disposed on the sliding portion, and the support portion is provided with a third driving member for driving the sliding portion to slide along the length direction of the support portion.

[0023] By adopting the above technical solution, when the support base is installed, the support part is installed on the base surface, and the sliding part is located above the support part. The soil loosening seat is driven to move by the first driving member, thereby loosening and tidying the soil within the coverage area of ​​the sliding part. After the soil within the coverage area of ​​the sliding part is loosened and tidyed, the sliding part can be driven to slide by the third driving member, thereby enabling the soil loosening seat to loosen and tidy the soil in a more distant range without moving or reinstalling the support base, thus improving the convenience of the device during use.

[0024] Optionally, the bottom of the support base is provided with a grounding rod for insertion into the base surface.

[0025] By adopting the above technical solution, when the support base is installed, the grounding rod is inserted into the base surface, thereby establishing a connection between the support base and the base surface, and improving the stability of the support base on the base surface.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When loosening the soil on the turf backfilling base surface, the support base is installed on the base surface, and the loosening seat is connected to the first drive component, so that the loosening seat is positioned above the base surface. Then, the first drive component drives the loosening seat to move along the length of the support base. The movement of the loosening seat drives the loosening roller to move. Simultaneously, the second drive component drives the loosening roller to rotate, which in turn drives the loosening blade to rotate while moving. The loosening blade thus turns over the soil on the base surface to complete the loosening. Because the loosening seat and the first drive component are detachably connected, the loosening seat and the support base can be separated during transportation and placement, thereby reducing the overall space required for the device and allowing it to be transported to the work site. Furthermore, during the entire process of loosening the base surface using this device, there is no need for manual labor to turn the soil with hand tools, thus improving loosening efficiency and reducing the intensity of manual operation. 2. The loosening blade consists of a fixed part and a movable part. The outer end of the movable part is pointed, which allows the movable part to better turn over the soil for loosening when it rotates with the loosening roller. However, during transportation and placement, the outer end of the movable part is exposed and easily touched by the operator, which may cause injury. Therefore, a placement groove is opened on the fixed part. When using the device for loosening and sorting operations, the movable part is rotated out so that the outer end of the movable part can contact the soil. After the device is used, the movable part is rotated in the direction close to the fixed part so that the movable part is rotated into the placement groove, thereby avoiding the outer end of the movable part being exposed. 3. When installing the support base, the support is installed on the base surface, and the sliding part is located above the support. The soil loosening seat is moved by the first driving component, thereby loosening and tidying the soil within the coverage area of ​​the sliding part. After the soil within the coverage area of ​​the sliding part is loosened and tidyed, the sliding part can be moved by the third driving component, so that the soil loosening seat can loosen and tidy the soil in a more distant range without moving or reinstalling the support base, thereby improving the convenience of the device during use.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a soil preparation device for high-altitude turf transplantation. (Refer to...) Figure 1 and Figure 2 The soil preparation device for high-altitude turf transplantation includes a support base 1, a first driving component 2 is provided on the support base 1, a loosening seat 3 is detachably connected to the first driving component 2, the first driving component 2 is used to drive the loosening seat 3 to move along the length direction of the support base 1; a loosening roller 4 is rotatably connected to the loosening seat 3, a second driving component 5 is provided on the loosening seat 3 to drive the loosening roller 4 to rotate, and the loosening roller 4 is provided with multiple rows of loosening blades 6 along the circumference.

[0031] Reference Figure 1 and Figure 3 There are two support bases 1, and each support base 1 has multiple insertion rods 18 fixed to its bottom for insertion into the base surface. The two support bases 1 are respectively located at both ends of the loosening base 3. The first driving component 2 includes a second motor 201 installed on one of the support bases 1. The output shaft of the second motor 201 is coaxially fixedly connected to a first lead screw 202, which is rotatably connected to this support base 1. A slide rod 19 parallel to the first lead screw 202 is fixed on the other support base 1. A first slider 24 is fixed on the lead screw nut of the first lead screw 202, and a second slider 25 is slidably connected to the slide rod 19. The loosening base 3 includes two loosening rods 301 rotatably located at both ends of the loosening roller 4. The two loosening rods 301 correspond to the first slider 24 and the second slider 25, respectively. Figure 1 and Figure 4 The first slider 24 and the second slider 25 are both fixed with insert rods 15. The loosening rod 301 is provided with a slot 16 for the corresponding insert rod 15 to be inserted. The slot 16 is provided with an anti-slip pad. The insert rod 15 is provided with a positioning pin 17, which is also inserted into the loosening rod 301.

[0032] When installing the support base 1, the insertion rod 18 is inserted into the base surface, thereby establishing a connection between the support base 1 and the base surface. When installing the loosening base 3, the two insertion rods 15 are inserted into the corresponding slots 16 respectively, and the positioning pins 17 are simultaneously inserted into the insertion rods 15 and the corresponding loosening rods 301, fixing the insertion rods 15 in the corresponding slots 16. This connects the two loosening rods 301 to the first slider 24 and the second slider 25 respectively, thereby establishing a connection between the loosening roller 4 and the first slider 24 and the second slider 25. The first slider 24 and the second slider 25 work together to provide support for the loosening roller 4. After this, the second motor 201 is driven to operate, and the operation of the second motor 201 drives the first lead screw 202 to rotate, thereby driving the first slider 24 to slide. The loosening rods 301 then drive the loosening roller 4 to slide synchronously with the first slider 24.

[0033] Reference Figure 1 and Figure 2 The support base 1 includes a support part 101 and a sliding part 102. A grounding rod 18 is fixed to the bottom end of the support part 101. A first lead screw 202 and a sliding rod 19 are respectively disposed on the corresponding sliding parts 102. A third driving member is disposed on the support part 101 to drive the sliding parts 102 to slide along the length direction of the support part 101. A roller 22 that can contact the base surface is rotatably disposed at one end of the sliding part 102. The third driving member includes a third motor 20 mounted on the support part 101. A second lead screw 21 is coaxially fixedly connected to the output shaft of the third motor 20. The second lead screw 21 is disposed along the length direction of the support part 101 and parallel to the first lead screw 202. The second lead screw 21 is rotatably connected to the support part 101. The lead screw nut of the second lead screw 21 is fixedly connected to the bottom end of the sliding part 102.

[0034] When the support base 1 is installed, the support part 101 is installed on the base surface, and the sliding part 102 is located above the support part 101. The second motor 201 is operated to drive the loosening rod 301 to move, and the loosening roller 4 loosens and arranges the soil within the length coverage area of ​​the sliding part 102. After the soil within the length coverage area of ​​the sliding part 102 is loosened and arranged, the third motor 20 is operated to drive the sliding part 102 to slide. During the sliding process, the roller 22 contacts the base surface and rolls, so the sliding part 102 can be stably unfolded, thereby allowing the loosening roller 4 to loosen and arrange the soil in a more distant range without moving or reinstalling the support base 1, thereby improving the convenience of the device during use.

[0035] Reference Figure 3 and Figure 4Two loosening rods 301 are each fixed with a connecting rod 23. A flat plate 13 is fixedly connected between the two connecting rods 23. Multiple leveling teeth 14 are fixed at the bottom of the flat plate 13. When the second motor 201 operates to drive the loosening rods 301 to move, the loosening rods 301 drive the flat plate 13 to move. The flat plate 13 then drives the multiple leveling teeth 14 to move synchronously. The leveling teeth 14 tidy up the base surface after it has been turned over and loosened by the loosening blades 6, so as to ensure the flatness of the base surface, thereby facilitating the subsequent re-laying of transplanted turf and ensuring the flatness of the transplanted turf re-laid into the base surface.

[0036] Reference Figure 3 and Figure 4 The loosening roller 4 has a receiving cavity 10. The second driving component 5 includes a first motor 501 disposed within the receiving cavity 10. A driving ring 11 is fixed to the output shaft of the first motor 501. Multiple driving rods 12 are fixed circumferentially on the driving ring 11. The end of each driving rod 12 away from the driving ring 11 is fixed to the inner wall of the loosening roller 4. The driving ring 11 is rotatably connected to one of the loosening rods 301. The first motor 501 operates to drive the output shaft to rotate, thereby rotating the driving rods 12. The rotation of the driving rods 12 drives the loosening roller 4 to rotate. 4. This drives the loosening blade 6 to rotate and loosen the soil. Since the first motor 501 is located inside the receiving cavity 10, the loosening roller 4 can protect the first motor 501 during its operation, preventing it from being directly exposed to the outside and from being splashed by soil when it is turned over, which could damage the first motor 501. In addition, the way the first motor 501 is located inside the receiving cavity 10 can further reduce the size of the device, making the overall structure of the device more compact and more conducive to the transportation and placement of the device.

[0037] Another tack rod 301 is fixedly connected to the middle of the end of the first motor 501 away from the output shaft. This tack rod 301 is hollow, and the wire for supplying power to the first motor 501 is located in this tack rod 301. A mating ring 28 is fixed on the tack rod 301, and multiple mating rods 29 are fixed circumferentially on the mating ring 28. The end of the mating rod 29 away from the mating ring 28 is attached to the inner wall of the tack roller 4 and slides with the tack roller 4. A storage battery for supplying power to the first motor 501 is installed inside the second slider 25. The storage battery is connected to the wire. A solar panel 27 connected to the storage battery is installed on the top of the second slider 25. The solar panel 27 operates by converting solar energy into electrical energy using the good sunlight conditions in the high-altitude area. The storage battery stores the electrical energy and uses it to supply power to the first motor 501 so that the first motor 501 can operate. A clearance hole for the power supply wire to pass through is opened in the middle of the insertion rod 15 connected to the second slider 25.

[0038] Reference Figure 4and Figure 5 The tack blade 6 includes a fixed part 601 fixed on the tack roller 4. A movable part 602 is hinged to one end of the fixed part 601 away from the tack roller 4. The movable part 602 is pointed at one end away from the hinge axis. A placement groove 7 is provided on the fixed part 601 for the movable part 602 to be inserted into the hinge axis. A damper is provided at the hinge axis of the movable part 602. A limiting plate 9 is integrally formed on the fixed part 601 to limit the rotation range of the movable part 602.

[0039] When the device is used for soil loosening, the movable part 602 is rotated away from the fixed part 601. When the movable part 602 rotates to abut against the limiting plate 9, the continued rotation of the movable part 602 in the same direction is restricted. After that, the first motor 501 drives the loosening roller 4 to rotate in the opposite direction to the above-mentioned rotation direction of the movable part 602. As a result, when the loosening roller 4 drives the loosening blade 6 to rotate, the movable part 602 will remain in contact with the limiting plate 9, thereby improving the stability of the movable part 602 in the process of rotating with the loosening roller 4 and preventing the movable part 602 from rotating in the direction closer to the fixed part 601 due to external resistance. Because the outer end of the movable part 602 is blade-shaped, it can better turn over the soil for loosening when it rotates with the loosening roller 4. However, when transporting and placing it, the outer end of the movable part 602 is exposed and is easily touched by the operator, which may cause injury to the operator. Therefore, a placement groove 7 is opened on the fixed part 601. When the device is used for loosening and sorting operations, the movable part 602 is turned out so that the outer end of the movable part 602 can contact the soil. After the device is used, the movable part 602 is rotated in the direction close to the fixed part 601, so that the movable part 602 is rotated into the placement groove 7, thereby avoiding the outer end of the movable part 602 being exposed.

[0040] Reference Figure 5 Each row of loosening blades 6 has a connecting rod 26 connecting each pair of movable parts 602. The combined action of multiple connecting rods 26 connects the loosening blades 6 in the same row into a whole. When it is necessary to rotate the movable part 602, the corresponding movable part 602 of the loosening blade 6 in the same row can be rotated synchronously through the cooperation of multiple connecting rods 26.

[0041] Reference Figure 5Two opposing cleaning seats 8 are provided at the opening of the placement groove 7. The cleaning seats 8 have clearance grooves for the connecting rod 26 to rotate into. The two cleaning seats 8 can respectively fit against the two sides of the movable part 602. The two cleaning seats 8 form a channel between them for the movable part 602 to rotate and insert into the placement groove 7. After the device is used, the movable part 602 is rotated in the direction close to the fixed part 601. During the process of the movable part 602 rotating into the placement groove 7, the two sides of the movable part 602 will fit against the cleaning seats 8. As the movable part 602 rotates, the two cleaning seats 8 will clean the two sides of the movable part 602 to prevent soil from adhering to the movable part 602 and entering the placement groove 7 with the movable part 602. After the soil enters the placement groove 7 and dries, it will be difficult for the movable part 602 to rotate out.

[0042] The implementation principle of the soil preparation device for high-altitude turf transplantation in this application embodiment is as follows: When it is necessary to loosen and prepare the soil on the turf back-laying base surface, the support part 101 is installed on the base surface, and the two loosening rods 301 are connected to the first slider 24 and the second slider 25 respectively, so that the loosening roller 4 is located above the base surface; then the second motor 201 operates to drive the loosening roller 4 to move along the length direction of the sliding part 102. At the same time, the first motor 501 operates to drive the loosening roller 4 to rotate. The loosening roller 4 thereby drives the loosening blade 6 to rotate while moving. The loosening blade 6 thereby turns over the soil on the base surface to complete the loosening of the base surface.

[0043] Since the two loosening rods 301 are detachably connected to the first slider 24 and the second slider 25 respectively, the loosening roller 4 and the support seat 1 can be separated when the device is transported and placed, thereby reducing the overall space required by the device so that the device can be transported to the work site. In the process of using the device to loosen the soil on the base surface, there is no need for manual hand tools to turn the soil, thereby improving the loosening efficiency and reducing the intensity of manual operation.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
