Description

Technical Field

[0001] The utility model relates to the technical field of gardening and greening, in particular to a pit digging device for gardening and greening. Background Art

[0002] Landscaping is the creation of a beautiful natural environment and recreational space in a certain area by using engineering technology and artistic means, transforming the terrain, planting trees and flowers, constructing buildings, and arranging garden paths. This is called a garden. When planting trees in landscaping, pits are usually dug using a pit digging device, and then the saplings are placed in the pits for cultivation.

[0003] Most of the pit digging devices perform the drilling and pit digging operations by rotating the drill rod, which moves downward into the soil. However, during the drilling and pit digging operation, the drill rod will discharge the soil upward, and the discharged soil will be scattered and accumulated around the surface of the pit. After the subsequent drilling and taking out, the accumulated soil is close to the pit mouth and is easily affected by the external environment and scattered into the pit, causing the pit depth to become shallower, affecting the subsequent seedling cultivation operations.
