Aloft pruning apparatus

Abstract

The invention discloses an aloft pruning apparatus comprising a threaded rod, a cutting base and a cutting assembly. The cutting assembly comprises two supporting blocks and a rotating shaft. The rotating shaft is sleeved with a gear saw web. The upper end of the threaded rod penetrates the cutting base, wherein a bevel gear located above the cutting base is installed on the tip of the upper end of the threaded rod. A tapered gear matched with the bevel gear is installed on the tip of one end of the rotating shaft. A hanging arm assembly comprises two hanging arm rods which have unequal lengths and are each in a reversed-J shape. Vertical parts of two hanging arm rods are both installed on the side wall of the cutting base. The aloft pruning apparatus further comprises antiskid blocks. In the aloft pruning apparatus, the hanging arm assembly is hung through the two hanging arm rods, stable clamping of branches and trunks is achieved, and therefore the cutting assembly can further stably do work for the branches and the trunks.

Description

technical field [0001] The invention relates to a gardening pruning device, in particular to a high-altitude pruning device. 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 the sta...

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.
