[0002] With the development of society, the application of landscaping is becoming more and more extensive. Landscaping is a beautiful natural environment and recreation area created by using engineering techniques and artistic means in a certain area through means such as transforming the terrain, planting trees and flowers, building buildings and arranging garden paths. Among them, when planting trees and flowers, it is necessary to dig pits for planting. At present, manual shovels are used to dig the ground, but traditional manual pit digging wastes physical strength, and it is not easy to control the depth and size.

[0003] In the prior art, for the pit digging device for landscaping with the patent number CN219612527U, it includes a trolley, a first support frame and a second support frame. The outer side of the upper end of the trolley is fixedly connected with the first support frame. The upper end of the first support frame is rotatably connected with a synchronous screw rod. The outer side of the synchronous screw rod is spirally connected with a lifting support plate. The middle position of the upper end of the lifting support plate is fixedly connected with a driving motor. The lower end of the output shaft of the driving motor is fixedly connected with a digging screw rod. In the utility model, through the synchronous screw rod, the soil protection frame and the worm gear, by rotating the worm gear, the worm wheel can rotate, so that the synchronous screw rods at the left and right ends can rotate simultaneously, so that the digging screw rod moves up and down, and by rotating the driving motor, the digging screw rod can continuously dig deeper, reducing the labor intensity of manual work. At the same time, through the function of the soil protection frame provided, it can avoid the scattered soil dug out, so as to facilitate the backfilling of the soil.

[0004] In the above device, after the tree pit is dug, workers need to carry the tree to the position of the tree pit. After the transfer, the tree needs to be vertically sent into the pit to ensure the vertical growth of the tree, and then the soil is backfilled. In the process of transferring the tree, the traditional manual method will consume more physical strength, and it is not easy to keep the tree vertically into the pit. Content of the Utility Model

The first support frame 3 is fixedly arranged on the upper surface of the first U-shaped bracket 1, and the first support rod 11 is fixedly arranged at the middle position between the two first U-shaped brackets 1, at a certain height from the ground, so that a spade can pass through, and then the turned soil can be backfilled.

[0022] Refer to Figure 1 , universal wheels 2 are symmetrically arranged on the lower surface of the first U-shaped bracket 1. The universal wheels 2 are of the prior art and can be purchased on the market according to the required size and model, and then fixed to the first U-shaped bracket 1 through bolts.

[0023] Refer toFigures 1-2 Inside the support frame 1 - 3, a lead screw 1 - 31 is rotatably arranged. On the surface of the lead screw 1 - 31, two sliders 1 - 32 are symmetrically threaded. The sliders 1 - 32 are slidably arranged inside the support frame 1 - 3. On the outer side surface of the support frame 1 - 3, a motor 1 - 311 is fixedly arranged. The output shaft of the motor 1 - 311 is fixed to one end of the lead screw 1 - 31. By driving the rotation of the lead screw 1 - 31 with the motor 1 - 311, the two sliders 1 - 32 can slide synchronously inside the support frame 1 - 3.

[0024] Reference Figure 1 Between the two support frames 1 - 3, a support frame 2 - 4 and a support rod 2 - 5 are symmetrically arranged. Each support frame 2 - 4 and support rod 2 - 5 corresponds to one slider 1 - 32 and is fixed to it.

[0025] Reference Figures 2-3 On the outer side surface of the support rod 1 - 11, a chute 1 - 2 is provided. On the lower outer side surfaces of the support frame 2 - 4 and the support rod 2 - 5, a sliding block 1 - 412 and a sliding block 2 - 511 are respectively fixedly arranged. The sliding block 1 - 412 and the sliding block 2 - 511 are both slidably arranged inside the chute 1 - 2 to improve the stability when the support rod 2 - 5 and the support frame 2 - 4 move.

[0026] Furthermore, the motors 1 - 311 on the outer side surfaces of the two support frames 1 - 3 drive the rotation of the two lead screws 1 - 31 synchronously, enabling the four sliders 1 - 32 to drive the support frame 2 - 4 and the support rod 2 - 5 to move synchronously.

[0027] Reference Figure 1 Inside the support frame 2 - 4, a lead screw 2 - 41 is rotatably arranged. On the surface of the lead screw 2 - 41, a slider 2 - 42 is threaded. The slider 2 - 42 is slidably arranged inside the support frame 2 - 4. At the upper end of the support frame 2 - 4, a motor 2 - 411 is fixedly arranged. The output shaft of the motor 2 - 411 is fixed to one end of the lead screw 2 - 41. Between the two sliders 2 - 42, a support plate 1 - 43 is fixedly arranged. On the upper surface of the support plate 1 - 43, a motor 3 - 44 is fixedly arranged. The output shaft of the motor 3 - 44 penetrates the surface of the support plate 1 - 43 and a spiral digging rod 4 - 5 is fixedly arranged on its lower end surface.

[0028] Furthermore, the motors 2 - 411 at the upper ends of the two support frames 1 - 3 drive the rotation of the lead screws 2 - 41 on both sides synchronously, enabling the sliders 2 - 42 on both sides to drive the support plate 1 - 43 to move up and down. Then, by driving the rotation of the spiral digging rod 4 - 5 with the motor 3 - 44, as the support plate 1 - 43 descends, the spiral digging rod 4 - 5 can dig holes in the land. By controlling the rotation of the lead screw 2 - 41, the depth of the holes dug by the spiral digging rod 4 - 5 can be effectively controlled, so that the holes are more suitable for the size and variety of the trees to be planted.

[0029] Reference Figure 4, symmetrically fixed between the two support rods II (5) is a support plate II (52). Symmetrically fixed on the outer side surface of the support plate II (52) are telescopic cylinders (51). Fixed to the outer end of the piston rod of the telescopic cylinder (51) is a clamping plate (53). The clamping plate (53) is slidably arranged on the outer side surface of the support plate II (52), and a number of rubber strips (531) are fixedly arranged on the outer surface of the clamping plate (53). The rubber strips (531) are used to protect the surface of the tree from being damaged by the clamping of the clamping plate (53).

[0030] Further, after the tree is brought close to the outer side surface of the support plate II (52), the telescopic cylinder (51) starts to drive the clamping plate (53) to fixedly clamp the tree. At this time, the upper surface and the lower surface of the tree are synchronously clamped by the two clamping plates (53), which can prevent the tree from tilting during the clamping process.

[0031] Further, after the planting hole is dug, by synchronously driving the rotation of the two lead screws I (31) through the motors I (311) on the outer side surfaces of the two support frames I (3), the spiral digging rod (45) can be moved away. At the same time, the clamped tree moves to the position of the hole. Then, the clamping of the clamping plate (53) on the tree is released, so that the tree vertically falls into the hole. Then, manually use a spade to cover the hole.
