Branch pruning mechanical arm

Abstract

A branch pruning mechanical arm consists of a base, a bottom cover, a rotary table, a big bevel gear, a small bevel gear, a motor, a vertical seat, a lifting oil cylinder, a lower arm, a flexible arm, a rotary head, a tilt angle oil cylinder, a disc saw flexible oil cylinder, a mechanical claw driving oil cylinder, a mechanical claw, a disc saw, a hydraulic motor and the like. The rotary table is driven by the motor to rotate by 360 degrees. The lifting oil cylinder is controlled to stretch, so that the mechanical arm can stand up. The flexible arm is driven by a traction wire rope or a gear rock to extend or retract node by node. A pruning mechanism can rotate by 360 degrees around the axis thereof by controlling the working head tilt angle oil cylinder and the rotary head. By controlling the oil cylinder to retract, the mechanical claw reliably clamps a to-be-pruned branch. The hydraulic motor drives the disc saw to rotate at a high speed, and controls the flexible oil cylinder to extend out at the same time, so that the disc saw gradually cuts off the to-be-pruned branch. By controlling the oil cylinder, the flexible arm and the rotary table, the pruned branches are reliably conveyed back to the ground, so that the branches are pruned.

Description

technical field [0001] The invention relates to a mechanical arm for pruning branches, belonging to the technical field of machinery. Background technique [0002] With the development of urbanization in China, the green areas of cities and towns are increasing. Every year before the typhoon season comes and in autumn, the trees need to be pruned to control the tree shape, and a large number of branches need to be pruned. However, it is more difficult to prune the higher branches. At present, the pruning is carried out by a branch pruning worker holding a cutting tool mainly by means of a movable lifting tool. Pruning branches is bigger to the labor intensity of workman like this, efficient is not high, and there is certain potential safety hazard during workman's operation. In addition, when the garden department trims branches on urban roads, since the pruned branches do not have clamping tools, when the larger branches are cut off, they will fall to the road. In order t...

Problems solved by technology

However, it is more difficult to prune branches with higher heights. At present, the pruning is mainly carried out by a branch pruning worker holding a cutting tool with the help of movable lifting tools

Pruning the branches like this is relatively labor-intensive to the workers, and the efficiency is not high, and there is a certain potential safety hazard during the workers' operations.

In addition, when the garden department trims branches on urban roads, since the pruned branches do not have clamping tools, when the larger branches are cut off, they will fall to the road. In order to avoid accidentally injuring passers-by and passing vehicles, they must Barricades are set up within the range of tree branch pruning, which will cause a lot of trouble to urban traffic
