Driving device for cycle motion of tree digging cutter

Abstract

The invention discloses a driving device for cycle motion of a tree digging cutter. The device is composed of a first retractable component, a first C-shaped slewing supporting component, two low-speed large-torque hydraulic motors, two first gears, two first clamping components, a second retractable component, a second C-shaped slewing supporting component, two second clamping components, a thirdretractable component, an amplitude-variation hydraulic oil cylinder, a fourth retractable component, a plate-type cantilever beam and two laser displacement sensors. A cylinder body of the amplitude-variation hydraulic oil cylinder is provided with double lugs, and a piston rod is provided with a single lug; the diameter at breast height of a tree trunk can be automatically measured, and the diameter and taper angle of soil balls can be automatically and conveniently adjusted; the cutter can be supported and conduct circular motion of different diameters and taper angles, and the soil ballsof different diameters and taper angles are cut; intelligent control and automatic operation are easily achieved, and the driving device for cycle motion is convenient to operate and high in working efficiency.

Description

technical field [0001] The invention relates to a tree-digging machine, in particular to a drive device for the rotary motion of a tree-digging tool. Background technique [0002] In the process of urban greening and garden landscape construction, it is necessary to dig out a large number of seedlings of different sizes from the nursery and transplant them to the city streets or in the garden landscape. In order to improve the survival rate of seedling transplanting, it is necessary to cut out standardized soil balls. Manual work is not only labor-intensive, but also has low efficiency and high cost, and the quality of seedling soil balls is difficult to guarantee. Contents of the invention [0003] The object of the present invention is to provide a driving device for the revolving motion of the tree-digging tool. [0004] The present invention consists of a first telescopic assembly, a first C-shaped slewing bearing assembly, two low-speed high-torque hydraulic motors, ...
