Description

Technical Field

[0001] The present invention relates to the technical field of garden construction excavation devices, and in particular to a garden construction excavation device and a use method thereof. Background Art

[0002] Landscape architecture is the creation of a beautiful natural environment and recreational space by using engineering technology and artistic means in a certain area, by transforming the terrain (or further building mountains, stacking stones, and managing water), planting trees, flowers, and plants, creating buildings, and arranging garden paths. Landscape architecture includes courtyards, residential gardens, small gardens, flower gardens, parks, botanical gardens, zoos, etc. With the development of landscape architecture, it also includes forest parks, scenic spots, nature reserves or national parks, and recreational resorts. When planting trees in landscape architecture, pits are usually dug using a pit digging device, and then the seedlings are placed in the pits for cultivation.

[0003] Among them, the pit digger is the main machine. The pit digger frees people from heavy physical labor and is widely used in afforestation. It is time-consuming and laborious to dig pits manually, and the efficiency is low. In addition, when planting trees, it is necessary to manually hold the trees, which takes up more human resources. Then other people fill the pit with soil, which is still time-consuming and laborious when filling the soil manually. The existing pit digging device for landscaping is generally composed of a pit digging motor, a spiral blade rod and a handrail frame. The overall structure is simple, lacks mobile and fixed structures, and generally requires manual support to complete. The labor intensity is large and the work efficiency is low. In addition, because manual support is required, the overall equipment has great hidden dangers when in use, and the equipment use height will also be limited, which will lead to the limitation of the pit digging depth, affecting the actual use effect. The soil pile formed by digging the pit is often piled up near the pit. When the excavation gradually goes deeper, the soil pile on the outside is easy to fall back into the pit, affecting the pit digging efficiency. Summary of the invention

When the lifting seat (31) descends, the limit rod (16) located at one end of the lifting seat (31) moves downward synchronously, so that the connecting seat (41) and the support plate (11) are in close contact, and at this time, the soil accumulation channel (45) in the cleaning component (4) is in close contact with the ground, and the cleaning drive device (42) drives the cleaning disc to rotate, so that a plurality of cleaning brushes (44) push the soil brought out by the digging rod along the direction of the soil accumulation channel (45); S4, the digging is finished, the torque output device (21) outputs in the reverse direction, drives the threaded rod (23) to rotate in the reverse direction, the lifting seat (31) moves upward, and the digging rod (35) is separated from the tunnel along with the rising of the connecting seat (41). When the lifting seat (31) moves upward, the limit rod (16) at one end of the lifting seat (31) moves upward synchronously, pulls up the connecting seat (41), and moves the soil accumulation channel (45) and the cleaning brush (44) close to the ground away from the ground; S5. The staff member grabs the push rod and pushes it, the push plate (6) rotates around the rotating interface (61), the connecting block (62) at the lower end of the push plate (6) moves away from the tilting block (54), the second spring (52) retracts to drive the stop plate (51) to rise, and the stop nail (53) is separated from the ground.
