Hydraulically-powered rotary digging device for small-type tree mover capable of protecting roots and conserving soil

Abstract

The invention provides a hydraulically-powered rotary digging device for a small-type tree mover capable of protecting roots and conserving soil. The device comprises a down tree digging member and an upper spiral arm rotary conveying member which is fixedly connected with the down tree digging member; the down tree digging member comprises a deep digging arm; a moving arm, a down deep digging arm and a deep digging shovel which are symmetrically arranged at left side and right side of the deep digging arm; the moving arm is slidingly clamped in a transverse slideway of the deep digging arm; a mounting seat is connected to the middle part of the deep digging arm; a hydraulic clamping cylinder is connected between the moving arm and the mounting seat; the moving arm is connected with a holding hoop sleeve through a hydraulic holding cylinder; the down deep digging arm is mounted at an end part of the moving arm; the down deep digging arm is provided with a dovetail slideway in longitudinal direction; the deep digging shovel is inwardly and obliquely downwards installed on a spacing slide block; the deep digging shovel is slidingly matched with the dovetail slideway through the spacing slide block whose upper part is fixedly connected to the deep digging shovel, and the deep digging shovel is controlled to lift up and down by a deep digging hydraulic cylinder which is mounted on the deep digging arm. The device of the invention has simple structure and is efficient and reliable to operate; automatic control is convenient to realize; root protection and soil conservation are fulfilled and survival rate of trees is increased.

Description

technical field [0001] The invention relates to equipment for tree digging construction, in particular to a hydraulically driven small tree digging machine rotary digging device capable of protecting roots and soil. Background technique [0002] In recent years, as people pay more attention to the living environment, "big trees into the city" has become an important means to rapidly increase the urban green area. When a big tree is transplanted, it must first be excavated, because ordinary excavators and other equipment can easily damage the roots of the big tree and reduce the survival rate of the transplant. Therefore, the work of digging trees is all done manually at present. The work efficiency is low, and it is easy to damage the roots of the trees in the process of digging the trees. At the same time, in order to improve the survival rate of the excavated trees, a mound should be made for their roots. This process must be done manually, which is very time-consuming a...
