Description

TECHNICAL FIELD

[0001] The utility model relates to a tree pruning device, belongs to the tree pruning device field. BACKGROUND

[0002] Tree pruning is an important horticultural activity that involves pruning, thinning or other treatment of tree branches to maintain the health, beauty and safety of trees. Tree pruning can promote the healthy growth of trees, improve fruit yield and quality, beautify tree shape, coordinate the proportion of trees and environment, adjust tree vigor and maintain ecological environment. In the prior art, different direction and angle branches grow on the trunk. Some branches are distributed relatively concentratedly. When using the tree pruning device to prune the bifurcation branches growing on the trunk, the cutting disc is driven to ascend and descend along the trunk by the power of the guide wheel, and then the output motor drives the gear to rotate so that the cutting disc rotates 360 degrees along the trunk. However, when the branches are distributed relatively densely, the cutting disc angle does not rotate in time, which can easily lead to missed branches that are not cut and pruned, thereby blocking the forward direction of the guide wheel and affecting the pruning progress of the branches. Therefore, it is necessary to design a tree pruning device that can increase the pruning efficiency of the cutting disc. SUMMARY
