Three-configuration metamorphic tree pruning and chopping machine with three-DOF (degree of freedom) transformation function

Abstract

A three-configuration metamorphic tree pruning and chopping machine with a three-DOF (degree of freedom) transformation function comprises a wood chopping combined mechanism, a crawler walking system, a rack, a driving linkage, a transmission linkage, an output connecting rod, pins, a hydraulic cylinder and a hook joint, wherein the rack is mounted on the crawler walking system, the driving linkage, the transmission linkage and the output connecting rod are mutually connected through the pins, the driving linkage and the transmission linkage are mounted on the rack, the wood chopping combined mechanism is mounted at one end of the output connecting rod through the hydraulic cylinder and the hook joint and comprises a saw mechanism, a lower clamping mechanism, rollers, an upper clamping mechanism and a branching knife. During working, flexible metamorphism of three-DOF and three-configuration transformation is realized, and large space operation is realized through overlaying of movement spaces; the tree pruning and chopping machine comprises full rod pieces and is lower in manufacturing cost, long in service life and simple to maintain. The tree pruning and chopping machine can prune, trim and chop trees and perform sectional wood cutting operation in severe and rugged forest.

Description

technical field [0001] The invention relates to the field of tree pruning and felling machines, in particular to a three-configuration metamorphic tree pruning and cutting machine with three degrees of freedom transformation. Background technique [0002] Chinese patent 201610396453.X discloses a logging robot, through the movement of four driving wheels, the positioning of cutting is realized, the working accuracy and flexibility are low, the movement space is small, and only the logging task can be realized; Chinese patent 201610419380.1 discloses a robot for The full hydraulic automatic logging device of the logging machine. This logging device is composed of full hydraulic components. The hydraulic components require high precision, the hydraulic system has high manufacturing costs, the working life is not long, oil leakage is easy, and the logging task can only be realized; Chinese patent 201210335835.3 Disclosed is an all-in-one tree felling and cutting machine, which ...
