[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1, as Figures 1-8 As shown, a self-soil-collecting and backfilling device for transplanting garden trees includes a movable support 1. The top of the movable support 1 is provided with a transplanting passage hole. The movable support 1 is provided with a lifting ring 3 that can be raised and lowered. The lifting ring 3 is provided with a soil-collecting and backfilling component. The soil-collecting and backfilling component includes a support ring 4 that is rotatably installed in the lifting ring 3. The bottom of the support ring 4 is annularly hinged with several swing frames 6, with 3-4 sets. The swing frames 6 can swing. The swing frames 6 are composed of a vertical part and an inclined installation part. A fourth hydraulic cylinder 7 is fixedly installed on the top of the inclined installation part. An outer shovel 8 is fixedly installed on the telescopic end of the fourth hydraulic cylinder 7. Several outer shovels 8 can form a complete conical outer bucket. The vertical part has a sliding groove 61 inside, and an inner shovel 9 is slidably connected inside the sliding groove 61. Several inner shovels 9 can form a complete conical inner bucket. The taper of the inner bucket is smaller than that of the outer bucket. Both sides of the inner shovel 9 are provided with dividing guards 92. When the inner bucket is fully inserted into the outer bucket, the dividing guards 92 are in close contact with the outer shovel 8.

[0023] Digging the hole: Move the movable support 1 directly above the digging position. At this time, the outer shovel blades 8 are at the top, with the outer shovel blades 8 moving away from each other and the inner shovel blades 9 coming together to form an inner bucket. Then start the equipment. The lifting ring 3 drives the support rotating ring 4 to descend, and the support rotating ring 4 drives the swing frame 6 to descend. The swing frame 6 drives the outer shovel blades 8 to descend vertically through the fourth hydraulic cylinder 7. When the tip of the outer shovel blades 8 descends to the surface of the soil, the descent stops. Then control several fourth hydraulic cylinders 7 to operate simultaneously. The fourth hydraulic cylinders 7 drive the outer shovel blades 8 to insert into the soil at an angle downwards. When multiple outer shovel blades 8 come together at an angle downwards, they form an outer bucket. The soil scooped in the outer bucket only occupies half the depth of the outer bucket. Then control the lifting ring 3 to rise. The lifting ring 3 drives the outer bucket to rise, and the outer bucket drives the soil inside it to rise, forming a cone-shaped transplanting pit at the transplanting position.

[0024] Splitting soil: control multiple inner spade pieces 9 to descend at the same time, the inner spade pieces 9 form an inner spade bucket, the inner spade bucket is inserted into the soil in the outer spade bucket, as the inner spade bucket continues to descend, the inner spade head extrudes the soil from the middle to the outside, when the inner spade bucket is fully inserted into the outer spade bucket, the split baffle 92 is attached to the inner wall of the outer spade bucket, at this time, the inner spade piece 9, the outer spade piece 8 and the two split baffles 92 form independent soil storage buckets, the soil in the outer spade bucket is divided into multiple parts, because the taper of the inner spade bucket is smaller than the taper of the outer spade bucket, therefore the inner space of the soil storage bucket is large enough, at the same time, the soil in the outer spade bucket only occupies half of the depth of the outer spade bucket, therefore after the soil is extruded, it will not overflow the soil storage space. Finally, control the swing frame 6 to swing outward, the swing frame 6 drives the soil storage bucket to swing outward, multiple soil storage buckets move away from each other, and the soil splitting is completed.

[0025] Transplanting: insert the transplanted trees from the transplanted through hole into the device, the transplanted trees fall into the transplanting pit through the support swivel 4, then control the inner spade piece 9 in one of the soil storage buckets to slide along the chute opening 61, the inner spade piece 9 moves away from the outer spade piece 8, at the same time, the support swivel 4 rotates, the support swivel 4 drives the soil storage bucket to rotate, and the soil is circularly scattered in the transplanting pit. After filling the soil once, manually sprinkle fertilizer and water, then tamp, then control the other soil storage buckets in turn to open, and perform layered soil filling. Through layered scattering and tamping, the close combination between the tree roots and the soil can be effectively promoted, the adhesion and stability of the roots are enhanced, which helps the tree to better adapt to the new environment after transplanting and improves the survival rate.

[0026] In summary, the device for transplanting trees can automatically dig holes, and the dug soil will not pollute the surrounding lawn, the overall transplanting process is clean, and the soil can be automatically and uniformly split, and the soil is layered after splitting, which greatly improves the survival rate of transplanted trees.
