Cedar branch pruning device for forestry

Abstract

The invention belongs to the technical field of forestry equipment and particularly relates to a cedar branch trimming device for forestry. To solve the problem that an existing pruning tool cannot prune branches dozens of meters high, the following scheme is provided: the device comprises a groove-shaped plate seat which is vertically arranged, the groove-shaped plate seat comprises two side protection plates and a middle plate, roller holes are formed in the upper and lower ends of the two side protection plates, roller driving boxes are arranged on the sides, close to the roller holes, of the opposite sides of the two side protection plates correspondingly, driving wheels are rotatably connected to the positions, close to the roller holes, of the roller driving boxes correspondingly, two parallel vertical plates are fixed to the edge of one side protection plate, and the same rotating shaft is rotatably connected between the two vertical plates. When the device is used, the device can drive a plain-end knife to rapidly make contact with small branches outside tree trunks when rapidly rushing upwards, and strong kinetic energy is matched with sharp knife edge support to smoothlycut off side branches.

Description

technical field [0001] The invention relates to the technical field of forestry equipment, in particular to a forestry fir branch pruning device. Background technique [0002] Many trees need to be pruned every year to ensure scientific and reasonable growth. The traditional pruning method is to prune by climbing a ladder or tie a knife with a bamboo pole. For example, pruning by climbing a ladder is difficult because of the complex environment in the woods. The moving ladder caused not only laborious but also time-consuming in the process of pruning; for pruning by binding knives on bamboo poles, because it is simply to bind tools such as knives on bamboo poles, it is necessary to cut off many thicker branches. It is a very strenuous thing. After a long time of operation, it is easy to cause blisters in the palm of the hand, and it is easy to cause fatigue in the arms and shoulders.
