Anti-vibration pole pruning saw

Abstract

The invention discloses an anti-vibration pole pruning saw. The anti-vibration pole pruning saw comprises a screw, a cutting pedestal and a cutting assembly. The cutting assembly comprises two support blocks and a rotating shaft, each support block comprises a lower part, an upper part and an elastic component, the rotating shaft is arranged on two upper parts through bearings in a rotary manner, and the head of one end of the rotating shaft is provided with a bevel gear. The anti-vibration pole pruning saw also comprises a hanging arm component, the hanging arm component comprises a hanging arm rod installed on the sidewall of the cutting pedestal and an inverted-J shaped hanging arm head, the upper end of the hanging arm rod is provided with a second accommodating groove which is concave inwards, the lower end of the vertical part of the hanging arm head is arranged in the second accommodating groove, and a first torsion spring fixedly connected with the vertical part of the hanging arm head is fixedly connected with the interior of the second accommodating groove. According to the invention, each upper part is movably connected with the corresponding lower part through one elastic component, thus, when the upper parts are under the acting force generated by a gear blade, the upper parts are pressed down, the elastic components are continuously compressed or recover from deformation, and therefore side-effect brought by vibration of the gear blade is eliminated.

Description

technical field [0001] The invention relates to a garden pruning device, in particular to an anti-vibration high-branch saw. 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.
