Device for cutting trees

Abstract

The invention discloses a device for cutting trees. The device comprises a threaded rod, a cutting base and a cutting assembly. The cutting assembly comprises two supporting blocks and a rotary shaft. The rotary shaft is sleeved with a gear saw web. The upper end of the threaded rod penetrates through the cutting base, and the tip of the upper end of the threaded rod is provided with a bevel gear located above the cutting base. The tip of one end of the rotary shaft is provided with a conical gear matched with the bevel gear. The device further comprises a hanger assembly which comprises a hanger rod and a hanger head. A containing groove is formed in the upper end of the hanger rod. The lower end of the vertical part of the hanger head is placed in the containing groove. A first torsional spring is fixedly connected in the containing groove. A sliding groove is formed in the lower end of the bent part of the hanger head. The device further comprises an anti-skid block. A sliding strip is arranged at the upper end of the anti-skid block. According to the device, when the position of a residual part and the position of a cut part are staggered slightly, external force can be applied to the hanger rod so that the hanger rod can rotate in a small range relative to the hanger head under the elastic deformation action of the first torsional spring, and thus the cutting demand is met.

Description

Technical field [0001] The invention relates to a gardening pruning device, in particular to a device for cutting trees. 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 the trees used for urban beautification is getting deeper, especially the trees on the lower side of the distribution lines. Therefore, the pruning of the trees on the lower side of the distribution line becomes the key to the safe operation of the urban line. If it is allowed to grow freely, the tree's own growth is likely to come into contact with the line, causing damage to the line or directly causing a short circuit between phases. , Not only will cause most of the power supply in the city to be suspended, but also may cause a fire in severe cases. In addition, the high-voltage current carried on the tree will injure passing pedestrians and pose a huge threat to the p...

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.
