Description

Technical Field

[0001] The present invention belongs to the technical field of seedling transplanting, and particularly relates to a seedling transplanting device and method. Background Art

[0002] A seedling transplanting device is a tool or equipment specifically designed to assist in the transplanting operation of seedlings. Common seedling transplanting devices include different forms such as transplanting shovels, transplanting buckets, and transplanting hanging baskets. The patent with the Chinese patent publication number CN220211294U discloses a seedling transplanting device applied to forestry, which relates to the technical field of forestry seedling planting, and includes a main body of the forestry seedling transplanting device. The main body of the forestry seedling transplanting device includes a seedling transplanting frame structure and a seedling fixing structure. This device can complete the three steps of shoveling, transporting, and transplanting seedlings at one time as a whole, and has the advantages of simple structure and convenient use, greatly improving the transplanting efficiency of forestry seedlings.

[0003] The problems existing in the prior art are as follows: When the existing device clamps, releases, and places the seedlings, it is necessary to manually adjust the threaded rods on both sides, which is cumbersome to operate, time-consuming, and inefficient. In addition, since the roots of the seedlings do not take root in the soil during transplanting and watering is required for the seedlings, the stability of the seedlings is poor. After transplanting, the entire device is removed, so the stability of the seedlings in the initial stage of transplanting cannot be guaranteed. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a seedling transplanting device, which has the advantages of automatically clamping, soil-digging, lowering, supporting, and limiting the seedlings, improving the seedling transplanting efficiency and automation degree, and solving the problems of cumbersome operation and low efficiency of the existing seedling transplanting device and the inability to guarantee the stability of the seedlings in the initial stage of transplanting.

[0005] The present invention is implemented as follows. A seedling transplanting device includes a fixed frame. At the front ends of both sides of the fixed frame, soil-digging components are rotatably installed. At the rear ends of both sides of the fixed frame, inserting rods are fixedly connected. At the upper end of the fixed frame, a fixing mechanism is fixedly connected. The fixing mechanism is arranged on one side of a clamping mechanism. The clamping mechanism is fixedly installed at the output end of a hydraulic cylinder. The hydraulic cylinder is fixedly installed on a trolley. The clamping mechanism includes a motor and an air pump. The output end of the motor is connected to a transmission component. Side plates are arranged at both ends of the transmission component. One end of the air pump is connected to a clamping component. The clamping component fixedly clamps the seedling body.

[0006] Preferably, an opening is provided at one end of the fixed frame away from the fixing mechanism. The soil-digging component is composed of a shovel and a rod body. The rod body is rotatably connected to the fixed frame. The bottoms of the two shovels are in contact. The roots of the seedling body are supported on the two shovels.

[0007] Preferably, the fixing mechanism includes two outer frames and clamping blocks. One side of one of the outer frames is hinged with a baffle, and one side of the baffle is clamped on the other outer frame. First limiting grooves are formed on the side walls of the two outer frames, and one side of each of the two clamping blocks is slidably connected in the first limiting grooves.

[0008] Preferably, second limiting grooves are formed on the inner side walls of the two clamping blocks. A threaded sleeve and a spring are fixedly connected to one side of each of the two clamping blocks. The spring is sleeved outside the threaded sleeve, and one end of the spring away from the clamping block is fixedly connected to the inner wall of the outer frame. The threaded sleeve slidably penetrates through the outer frame, and a screw rod is threadedly connected in the threaded sleeve.

[0009] Preferably, the clamping mechanism further includes a box body and a guiding cover. One side of the box body is fixedly connected with a mounting plate, and the mounting plate is fixedly connected to the output end of a hydraulic cylinder. The guiding cover is fixedly connected to the upper surface of the box body. A connecting frame is fixedly connected to the bottom of the box body, and first insertion blocks are fixedly connected to both ends of the connecting frame. The two first insertion blocks are respectively inserted into one side of the two rod bodies.

[0010] Preferably, both the motor and the air pump are fixedly installed on the top of the box body. The transmission assembly includes a gear, a rack, a rotating shaft, a worm and a worm gear. The top end of the rotating shaft is fixedly connected to the output end of the motor, and the bottom end of the rotating shaft is rotatably installed on the inner bottom wall of the box body. The gear is located above the box body and fixedly sleeved on the rotating shaft. The worm is fixedly sleeved on the middle shaft body of the rotating shaft. The worm gear is located on one side of the worm and meshed with it. The gear is meshed with the racks on both sides.

[0011] Preferably, the two racks are respectively slidably connected to both sides inside the guiding cover. Side plates are respectively fixedly connected to the ends of the two racks. Two second insertion blocks are fixedly connected to one side of the box body, and the two second insertion blocks are respectively inserted into the two outer frames.

[0012] Preferably, the clamping assembly includes an I-shaped shaft and two air bags. The I-shaped shaft is rotatably installed in the box body. The worm gear is fixedly sleeved on the middle of the I-shaped shaft. One end of each of the two air bags is wound around both ends of the I-shaped shaft. The other ends of the two air bags are both fixedly connected with limiting blocks. The two limiting blocks are respectively slidably connected with the two second limiting grooves. After the two air bags are inflated by the air pump, the seedling body is clamped.

[0013] The present invention also provides a using method of the seedling transplanting device, which specifically includes the following steps: Seedling loading: Open the baffle and place the seedling body between the two clamping blocks, with its roots positioned on the two shovels. Then start the air pump to inflate the airbag. During the inflation process of the airbag, the clamping blocks gradually compress the spring under the push of the airbag until one end of the clamping block abuts against the second insertion block, fixing the position of the clamping block. As the airbag continues to inflate and expand, the clamping of the seedling body is achieved, completing the loading; Initial fixation: Move the device to the transplanting site by the trolley. Then start the hydraulic cylinder to drive the fixing frame, fixing mechanism, clamping mechanism, soil-digging component and the seedling body to move downward, so that the bottom of the insertion rod first inserts into the soil to fix the fixing frame. Subsequently, the bottoms of the two shovels insert into the soil partially; Seedling lowering: Deflate the airbag through the air pump. Then start the motor to drive the transmission component to work. The motor drives the gear to rotate, causing the two racks to drive the side plates closer. The two side plates simultaneously push the rod body inward, causing the soil-digging component to flip. The two shovels push the soil outward. After the airbag is deflated, the worm drives the I-shaped shaft to rotate, winding up the airbag so that it disengages from the outer frame, thus loosening the seedling body. Subsequently, under the action of gravity, the seedling body falls downward and lands in the middle of the dug soil, completing the lowering; Seedling limiting: During the flipping process of the rod body, the screw rod is squeezed inward. The screw rod drives the threaded sleeve and the clamping block to move inward, moving the clamping block to a position close to the seedling body to prevent the seedling body from tilting during the soil filling process. Then soil filling is carried out. When filling the soil, the soil simultaneously covers the roots of the seedling body and the bottoms of the shovels. If the soil-digging component is not required to fix the seedling body subsequently, there is no need to fill the soil for the shovels.

[0014] Device separation: Move the hydraulic cylinder and the clamping mechanism outward, so that the second insertion block disengages from the outer frame and the first insertion block disengages from the rod body, realizing the separation of the clamping mechanism from the fixing mechanism and the soil-digging component. If it is necessary to fix the seedling body, leave the soil-digging component and the fixing frame. During the subsequent growth process of the seedling body, the screw rod can be rotated to drive the threaded sleeve to drive the clamping block to move outward, expanding the space in the middle of the clamping block, which is beneficial to the growth of the seedling body. If it is not necessary to fix the seedling body, open the baffle, pull out the fixing frame upward, and remove the fixing frame, fixing mechanism and soil-digging component from around the seedling body.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the insertion rod to insert into the soil first, the device can be initially fixed, improving the stability of subsequent operations. By setting two soil-digging components, it can play a role in supporting and protecting the roots of the seedling body before transplantation, avoiding damage to the roots caused by impact. During transplantation, by inserting the soil-digging component into the soil and then flipping it outward, the soil can be pushed outward, facilitating the seedling body to fall into the dug pit, realizing automatic soil digging and greatly reducing the labor intensity of workers.

[0016] The present invention can limit the position of the seedling body by pushing the clamping block inward through the soil-digging component so that it approaches the seedling body, avoiding tilting during the subsequent soil filling process. After transplantation, soil is filled around the seedling body to fix it. Whether to use the fixing mechanism and the soil-digging component to support and fix it can be selected according to the situation of the seedling. If needed, soil is filled around the soil-digging component. The clamping block is pushed by the soil-digging component to limit the position of the seedling body, and the two sides of the seedling body are supported by the soil-digging component. If not needed, the device is separated and removed. Therefore, it can be selected according to the specific usage scenario, with high flexibility. The removed components can be reused, saving costs.

[0017] By setting the clamping mechanism, the present invention can clamp and lower the seedling body during transplantation, and realize automatic soil digging and support and limitation by driving the soil-digging component and the fixing mechanism to move, greatly reducing the manual labor intensity, improving the automation degree, and also ensuring the stability of the seedling during and after transplantation.

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail with reference to the accompanying drawings as follows.

[0021] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1 to 10 shown, a seedling transplanting device provided by an embodiment of the present invention includes a fixed frame 1. Soil-scraping assemblies 4 are rotatably installed at the front ends of both sides of the fixed frame 1. Insert rods 11 are fixedly connected to the rear ends of both sides of the fixed frame 1. A fixing mechanism 2 is fixedly connected to the upper end of the fixed frame 1. The fixing mechanism 2 is arranged on one side of a clamping mechanism 3. The clamping mechanism 3 is fixedly installed at the output end of a hydraulic cylinder 5. The hydraulic cylinder 5 is fixedly installed on a trolley. The clamping mechanism 3 includes a motor 33 and an air pump 34. The output end of the motor 33 is connected with a transmission assembly. Side plates 39 are arranged at both ends of the transmission assembly. One end of the air pump 34 is connected with a clamping assembly 314. The clamping assembly 314 fixedly clamps the seedling body 6.

[0023] Furthermore, an opening is arranged at one end of the fixed frame 1 away from the fixing mechanism 2. The soil-scraping assembly 4 consists of a shovel 41 and a rod body 42. The rod body 42 is rotatably connected to the fixed frame 1. The bottoms of the two shovels 41 are in contact. The root of the seedling body 6 is supported on the two shovels 41.

[0024] Specifically, in the initial state, the two soil-digging components 4 are in a V shape, and the root of the seedling body 6 is located between the two shovels 41. The two shovels 41 first support the root of the seedling body 6, and then turn over under the drive of the clamping mechanism 3 to push the soil outward, facilitating the transplanting of the seedling body 6. After turning outward, the seedling body 6 is limited by the extrusion fixing mechanism 2 to prevent the seedling body 6 from tilting, and the seedling body 6 is supported from both sides to improve the stability during the growth process of the seedling body 6. If subsequent support for the seedling body 6 is not required, the fixing frame 1, the fixing mechanism 2, and the soil-digging components 4 can also be removed, which can be selected according to the specific usage scenario, with high flexibility, and the removed components can be reused to save costs.

[0025] Further, the fixing mechanism 2 includes two outer frames 21 and clamping blocks 23. One side of one outer frame 21 is hinged with a baffle 22, and one side of the baffle 22 is clamped on the other outer frame 21. First limiting grooves 2101 are formed on the side walls of the two outer frames 21. One side of the two clamping blocks 23 is respectively slidably connected in the first limiting grooves 2101. Second limiting grooves 2301 are formed on the inner side walls of the two clamping blocks 23. One side of each of the two clamping blocks 23 is fixedly connected with a threaded sleeve 26 and a spring 25. The spring 25 is sleeved outside the threaded sleeve 26. The end of the spring 25 away from the clamping block 23 is fixedly connected with the inner wall of the outer frame 21. The threaded sleeve 26 slidably penetrates through the outer frame 21, and a screw rod 24 is threadedly connected in the threaded sleeve 26.

[0026] Specifically, the two outer frames 21 are respectively fixedly installed at the two upper ends of the fixing frame 1. By providing the openable baffle 22, it is convenient to move the seedling body 6 between the two clamping blocks 23 or move it out therefrom. By providing the first limiting grooves 2101, one end of the clamping block 23 is slidably connected in the first limiting grooves 2101, which can limit the clamping block 23 and enable the clamping block 23 to move horizontally in the outer frame 21. In the initial state, one end of the two clamping blocks 23 is located in the middle of the first limiting grooves 2101, and the clamping block 23 can move inward or outward along the first limiting grooves 2101.

[0027] During use, after the seedling body 6 is placed, the airbag 302 is inflated to push the clamping block 23 outward until one end of the clamping block 23 abuts against the second insertion block 313. When continuously inflating, the position of the clamping block 23 remains unchanged, and the airbag 302 squeezes the seedling body 6 inward to clamp the seedling body 6. After deflating, the seedling body 6 drops, and the clamping block 23 moves inward to reset but does not contact the seedling body 6. The soil-digging component 4 turns inward and pushes the clamping block 23 to move to a position close to the seedling body 6 with a small distance, which can effectively prevent the seedling body 6 from tilting.

[0028] During subsequent use, as the seedling body 6 grows, the position of the clamping block 23 can be adjusted. When adjusting, the upper end of the rod body 42 abuts against one side of the screw rod 24. By rotating the screw rod 24, the threaded sleeve 26 can be driven to move outwards, and the threaded sleeve 26 drives the clamping block 23 to move outwards, expanding the internal accommodation space, so as to better adapt to the growth of the seedling body 6.

[0029] Furthermore, the clamping mechanism 3 further includes a box body 31 and a guide cover 32. One side of the box body 31 is fixedly connected with a mounting plate 51, and the mounting plate 51 is fixedly connected to the output end of the hydraulic cylinder 5. The guide cover 32 is fixedly connected to the upper surface of the box body 31. The bottom of the box body 31 is fixedly connected with a connecting frame 35. Both ends of the connecting frame 35 are fixedly connected with a first insertion block 36, and the two first insertion blocks 36 are respectively inserted into one side of the two rod bodies 42.

[0030] Specifically, the hydraulic cylinder 5 is fixedly installed on a trolley, and a mobile power source is loaded on the trolley to supply power to electrical equipment, which is convenient for outdoor mobile use. By starting the hydraulic cylinder 5 to drive the device to move downwards, the insertion rod 11 is preferentially inserted into the soil, and then the bottom of the shovel 41 is inserted into the soil to realize the preliminary fixation of the device. By arranging the first insertion block 36 to be inserted into the rod body 42, the strength and stability of the rod body 42 can be improved.

[0031] Furthermore, the motor 33 and the air pump 34 are both fixedly installed on the top of the box body 31. The transmission assembly includes a gear 37, a rack 38, a rotating shaft 310, a worm 311 and a worm gear 312. The top end of the rotating shaft 310 is fixedly connected to the output end of the motor 33, and the bottom end of the rotating shaft 310 is rotatably installed on the bottom inner wall of the box body 31. The gear 37 is located above the box body 31 and fixedly sleeved on the rotating shaft 310. The worm 311 is fixedly sleeved on the middle shaft body of the rotating shaft 310. The worm gear 312 is located on one side of the worm 311 and meshed with it. Both sides of the gear 37 are meshed with a rack 38, and the two racks 38 are respectively slidably connected to both sides inside the guide cover 32. Two side plates 39 are respectively fixedly connected to the ends of the two racks 38. Two second insertion blocks 313 are fixedly connected to one side of the box body 31, and the two second insertion blocks 313 are respectively inserted into the two outer frames 21.

[0032] Specifically, the transmission assembly can realize the retraction of the airbag 302 and the movement of the two side plates 39. The air pump 34 is connected to the two airbags 302 through two hoses respectively, and the airbags 302 can be inflated and deflated. When inflating, the airbag 302 clamps the seedling body 6 without causing damage to the seedling body 6. When deflating, the seedling body 6 becomes loose and falls under the action of gravity. Then, the airbag 302 is pulled out of the outer frame 21 through the transmission assembly, which is convenient for the subsequent detachment of the device.

[0033] When in use, the motor 33 is started to drive the rotating shaft 310 and the worm 311 to rotate, and the meshing connection between the worm 311 and the worm wheel 312 makes the worm wheel 312 drive the I-shaft 301 and the airbag 302 to rotate synchronously, so that the limit block 303 slides in the second limit groove 2301 until it slides to the end of the second limit groove 2301. After separation, the limit block 303 automatically disengages from the second limit groove 2301, and drives the gear 37 to rotate through the rotating shaft 310. The gear 37 drives the two racks 38 to move inward at the same time, thereby driving the side plates 39 on both sides to move inward, and the soil-moving components 4 on both sides rotate, and the soil is pushed to both sides, so that the roots of the seedling body 6 fall into the pushed soil.

[0034] Furthermore, the clamping assembly 314 includes an I-beam shaft 301 and two air bags 302. The I-beam shaft 301 is rotatably installed in the box body 31. The worm gear 312 is fixedly sleeved on the middle part of the I-beam shaft 301. One ends of the two air bags 302 are respectively wrapped around the two ends of the I-beam shaft 301. The other ends of the two air bags 302 are fixedly connected to the limiting blocks 303. The two limiting blocks 303 are respectively slidably connected to the two second limiting grooves 2301. The two air bags 302 are inflated by the air pump 34 to clamp the seedling body 6.

[0035] When in use, the limit block 303 is moved to one end of the second limit groove 2301 close to the baffle 22, and then the seedling body 6 is placed between the two air bags 302, and the air pump 34 is started to inflate the air bags 302. The air bags 302 first push the clamping block 23 outward until one end of the clamping block 23 abuts against the second plug block 313. After the position of the clamping block 23 is fixed, the air bag 302 continues to expand and clamps the seedling body 6 inward to fix the seedling body 6. After the air bag 302 is deflated and retracted, the clamping block 23 is first reset to the middle of the second limit groove 2301 under the elastic force of the spring 25, and then approaches the seedling body 6 under the push of the soil-moving assembly 4. When the clamping mechanism 3 is separated, the second plug block 313 is separated from the outer frame 21. In this state, the clamping block 23 can move outward a larger distance, thereby further increasing the space in the middle.

[0036] like Figures 1 - 10 As shown, a method for using a seedling transplanting device provided in an embodiment of the present invention comprises the following steps: For seedling loading, the baffle 22 is opened to place the seedling body 6 between the two clamping blocks 23 so that its root is located on the two shovels 41, and then the air pump 34 is started to inflate the airbag 302. During the inflation of the airbag 302, the clamping block 23 gradually compresses the spring 25 under the push of the airbag 302 until one end of the clamping block 23 abuts against the second plug 313, so that the position of the clamping block 23 is fixed. As the airbag 302 continues to inflate, the seedling body 6 is clamped, and the loading is completed; After initial fixation, the device is moved to the transplanting site by a trolley, and then the hydraulic cylinder 5 is started to drive the fixing frame 1, the fixing mechanism 2, the clamping mechanism 3, the soil-moving assembly 4 and the seedling body 6 to move downward, so that the bottom of the insertion rod 11 is first inserted into the soil, so that the fixing frame 1 is fixed, and then the bottoms of the two shovels 41 are partially inserted into the soil; When the seedlings are lowered, the air bag 302 is deflated by the air pump 34, and then the motor 33 is started to drive the transmission assembly to work. The motor 33 drives the gear 37 to rotate, so that the two racks 38 drive the side plates 39 to approach each other, and the two side plates 39 simultaneously push the rod body 42 inward, so that the soil-moving assembly 4 is turned over, and the two shovels 41 move the soil outward. After the air bag 302 is deflated, the worm gear 312 drives the I-shaped shaft 301 to rotate, and the air bag 302 is rolled up, so that it is separated from the outer frame 21, so that the seedling body 6 is loosened, and then falls downward under the action of gravity, falls to the middle of the soil that has been moved, and the lowering is completed; The seedlings are limited in position. During the flipping process of the rod body 42, the screw 24 is squeezed inward, and the screw 24 drives the threaded sleeve 26 and the clamping block 23 to move inward, so that the clamping block 23 moves to a position close to the seedling body 6, to prevent the seedling body 6 from tilting during the soiling and watering process. Then the soiling is carried out, and the soil covers the roots of the seedling body 6 and the bottom of the shovel 41 at the same time. If the soil-moving assembly 4 is not needed to fix the seedling body 6 later, there is no need to add soil to the shovel 41.

[0037] The device is separated, and the hydraulic cylinder 5 and the clamping mechanism 3 are moved outward to disengage the second plug block 313 from the outer frame 21, and the first plug block 36 is disengaged from the rod body 42, thereby realizing the separation of the clamping mechanism 3 from the fixing mechanism 2 and the soil-moving assembly 4. If it is necessary to fix the seedling body 6, the soil-moving assembly 4 and the fixing frame 1 are left behind. In the subsequent growth process of the seedling body 6, the threaded sleeve 26 can be driven by rotating the screw 24 to drive the clamping block 23 to move outward, thereby expanding the middle space of the clamping block 23, which is beneficial to the growth of the seedling body 6. If it is not necessary to fix the seedling body 6, the baffle 22 is opened, the fixing frame 1 is pulled out upward, and the fixing frame 1, the fixing mechanism 2 and the soil-moving assembly 4 are removed from around the seedling body 6.

[0038] In summary, for the seedling transplanting device, by inserting the insertion rod 11 into the soil first, the device can be initially fixed, improving the stability of subsequent operations. By providing two soil-dialing components 4, it can support and protect the roots of the seedling body 6 before transplantation, avoiding damage to the roots caused by impacts. During transplantation, by inserting the soil-dialing components 4 into the soil and then turning them outwards, the soil can be dialed outwards, facilitating the seedling body 6 to fall into the dug pit, realizing automatic soil dialing, greatly reducing the labor intensity of workers. Moreover, by pushing the clamping block 23 to move inwards by the soil-dialing component 4 to make it close to the seedling body 6, it can limit the position of the seedling body 6, preventing it from tilting during subsequent soil filling and watering processes. After transplantation, soil is filled around the seedling body 6 to fix it. Whether to use the fixing mechanism 2 and the soil-dialing component 4 to support and fix it can be selected according to the situation of the seedlings. If needed, soil is filled around the soil-dialing component 4. The soil-dialing component 4 pushes the clamping block 23 to limit the position of the seedling body 6, and the soil-dialing component 4 supports both sides of the seedling body 6. If not needed, the device is separated and removed. Thus, it can be selected according to the specific usage scenario, with high flexibility. The removed components can be reused, saving costs. By providing the clamping mechanism 3, the seedling body 6 can be clamped and lowered during transplantation. By driving the soil-dialing component 4 and the fixing mechanism 2 to move, automatic soil dialing and support limiting are realized, greatly reducing the labor intensity of workers, improving the degree of automation, and also ensuring the stability during and after the seedling transplantation process.

9. A method of a seedling transplanting device, characterized in that: A seedling transplanting device according to any one of claims 1 to 8, comprising the following steps: Seedling loading: Open the baffle (22) and place the seedling body (6) between the two clamping blocks (23) so that its root is located on the two shovels (41). Then start the air pump (34) to inflate the air bag (302). During the inflation process of the air bag (302), the clamping block (23) gradually compresses the spring (25) under the push of the air bag (302) until one end of the clamping block (23) abuts against the second insertion block (313) to fix the position of the clamping block (23). As the air bag (302) continues to inflate and expand, the clamping of the seedling body (6) is realized to complete the loading; Preliminary fixation: Move the device to the transplanting site by a trolley. Then start the hydraulic cylinder (5) to drive the fixing frame (1), the fixing mechanism (2), the clamping mechanism (3), the soil-digging component (4) and the seedling body (6) to move downward so that the bottom of the inserting rod (11) is first inserted into the soil to fix the fixing frame (1). Then the bottoms of the two shovels (41) are inserted into the soil for a certain part; Lower the seedlings. Deflate the airbag (302) through the air pump (34). Then start the motor (33) to drive the transmission component to work. The motor (33) drives the gear (37) to rotate, causing the two racks (38) to drive the side plates (39) closer to each other. The two side plates (39) simultaneously push the rod body (42) inward, causing the soil-digging component (4) to flip. The two shovels (41) push the soil outward. After the airbag (302) is deflated, the worm gear (312) drives the I-beam shaft (301) to rotate, winding up the airbag (302) so that it disengages from the outer frame (21), thereby loosening the seedling body (6). Then, under the action of gravity, it falls downward and lands in the middle of the dug soil to complete the lowering; Limit the seedlings. During the flipping process of the rod body (42), it squeezes the screw rod (24) inward. The screw rod (24) drives the threaded sleeve (26) and the clamping block (23) to move inward, causing the clamping block (23) to move to a position close to the seedling body (6) to prevent the seedling body (6) from tilting during soil cultivation. Then, soil cultivation is carried out. When cultivating the soil, the soil simultaneously covers the root of the seedling body (6) and the bottom of the shovel (41). If the soil-digging component (4) is not required to fix the seedling body (6) subsequently, there is no need to cultivate the soil for the shovel (41).

10. The method of the seedling transplanting device according to claim 9, characterized in that, Including the following steps: Separate the device. Move the hydraulic cylinder (5) and the clamping mechanism (3) outward so that the second insert block (313) disengages from the outer frame (21) and the first insert block (36) disengages from the rod body (42), realizing the separation of the clamping mechanism (3) from the fixing mechanism (2) and the soil-digging component (4). If it is necessary to fix the seedling body (6), leave the soil-digging component (4) and the fixing frame (1). During the subsequent growth process of the seedling body (6), the threaded sleeve (26) can be driven to move the clamping block (23) outward by rotating the screw rod (24) to expand the space in the middle of the clamping block (23), which is beneficial to the growth of the seedling body (6). If it is not necessary to fix the seedling body (6), open the baffle (22), pull out the fixing frame (1) upward, and remove the fixing frame (1), the fixing mechanism (2), and the soil-digging component (4) from around the seedling body (6).
