Description

Technical Field

[0001] The utility model relates to a pit digging device, in particular to a tree planting pit digging device, belonging to the technical field of gardening. Background Art

[0002] As is known to all, in the prior art, a pit digging device is required to dig a pit when planting trees, and then the roots of the trees are inserted into the planting pits and filled with soil to complete the planting of the trees. In order to solve the problem that a small pit digging device is relatively wasteful when moving over a long distance, a Chinese patent publication (publication number: CN219577804U) discloses a pit digging device for tree planting, the technical solution of which is as follows: it comprises a fixed plate, a power assembly is fixedly installed on the upper side of the fixed plate, and a drill rod connected to the power assembly is arranged on the lower side of the fixed plate, and a pair of power assemblies are rotatably installed on both sides of the fixed plate. The supporting bracket is locked and fixed with the fixing plate in the horizontal state, and the bracket can be rotated downward at a right angle. Travel wheels are provided on the front and rear sides of the bracket near one end, and a handle which can be unfolded and folded is provided on the fixing plate. The two brackets are convenient for the operator to support when digging a pit. When the pit digging equipment is moved over a long distance, the brackets on both sides are rotated downward at a right angle to make it in a vertical state. At this time, the travel wheels are supported on the ground, and then the position can be moved by dragging the handle, which makes the long-distance movement of the pit digging equipment easier and more labor-saving.

[0003] However, the technical solution of the above patent still has shortcomings: since the prior art lacks a structural setting for fixing the walking wheels, the bracket is insufficiently stable when placed, which easily leads to the safety hazard of accidental sliding of the digging equipment during placement and thus causing collision; for this reason, a tree planting digging equipment is proposed.
