Description

Technical Field

[0001] The utility model relates to a forestry insect-proof peeling and pruning device, belonging to the technical field of forestry insect-proofing. Background Art

[0002] The main hazards to forests are diseases and pests, so it is necessary to use control measures to carry out protective treatment against diseases and pests. Usually, the branches at the location of the disease and pests are peeled, and then the location is treated. The purpose of tree peeling is to improve the quality of the trees and prevent diseases and pests. At the same time, peeling can also destroy the living environment of diseases and pests on the surface and inside of the trees, reducing the occurrence and spread of diseases and pests.

[0003] The existing patent number is CN216358088U, which is a forestry insect-proof pruning and peeling device. This device can drive the peeling cutter to perform circular cutting on the branches by rotating the support ring, and can push the movable rod to drive the peeling cutter to move, so that the cutting depth can be adjusted, which not only increases the convenience of bark cutting, but also ensures the integrity of the incision. However, in this device, the support ring is only rotated and opened by means of a magnet block. This connection method is not stable enough. It is easy to cause the support ring to open due to the expansion effect during the process of peeling and pruning the branches, affecting the stability of peeling and pruning. Moreover, the method of driving the peeling cutter to move only by pushing the movable rod is not accurate enough, and it is difficult to accurately adjust the depth according to the thickness of the branch. In addition, the movable rod needs to be continuously pressed during the peeling process, and it is difficult to rotate the device as a whole, which makes it difficult to operate when used by one person.
