Cutting device for high tree branches

Abstract

The invention discloses a cutting device for high tree branches. The cutting device comprises a screw rod, a cutting base, a cutting assembly and a hanging arm assembly; the cutting assembly comprises two supporting block and a rotating shaft; and the hanging arm assembly comprises a short hanging arm rod, a long hanging arm rod, a first hanging arm head, a second hanging arm head and an arc-shaped anti-slipping block, and the widths of the first hanging arm head and the second hanging arm head in the axis directions of bending portions of the first hanging arm head and the second hanging arm head are both smaller than the width of the anti-slipping block in the corresponding axial directions. By installing a spring and a first torsional spring, branch cutting work of the cutting assembly can be better achieved due to the fact that the elastic deformation of the spring and the torsional spring gives way to gear saw blades, and particularly, when the positions of a residual part and a cutting part are slightly mismatched, cutting requirements can be met by the way that external force is applied to the long hanging arm rod, and thus the long hanging arm rod rotates on a small scale relative to the second hanging arm head under the effect of the elastic deformation of the first torsional spring.

Description

technical field [0001] The invention relates to a garden pruning device, in particular to a cutter for high-altitude tree branches. Background technique [0002] At present, it has become a common phenomenon for distribution lines to cross streets and alleys, but the tree-line contradiction between distribution lines and trees used for urban beautification is deepening day by day, especially the trees on the lower side of distribution lines. Therefore, the pruning of trees on the lower side of distribution lines is the key to the safe operation of urban lines. If they are allowed to grow freely, the growth of trees is likely to touch the lines, causing damage to the lines or directly causing phase-to-phase short circuits. , Not only will the power supply of most of the urban area be interrupted, but it may also cause a fire in severe cases. In addition, the high-voltage current on the tree body will hurt passing pedestrians, and pose a huge threat to the personal safety of ...

AI Technical Summary

Problems solved by technology

The traditional treatment method is to manually use tools such as knives to trim branches or trees on the distribution line before laying the line, but this method is dangerous to operate and the personal safety of the staff cannot be guaranteed; The aerial work vehicle is modified. This method is simple to operate and has a high safety factor. However, the use cost of the aerial work vehicle is high and the applicable environment is limited.
