Abstract

The invention relates to a drill rod for a hydraulic crushing hammer, and belongs to the technical field of hydraulic crushing hammers. The drill rod comprises a drill rod body, a buffering structureand a drill rod head, the drill rod body is detachably connected with the buffering structure through bolts, and the buffering structure is detachably connected with the drill rod head through bolts.Compared with the prior art, the drill rod for the hydraulic crushing hammer has the advantages that the production cost is reduced, the buffering and damping effects are excellent, and the service life of each part of the hydraulic crushing hammer is prolonged.

Description

technical field [0001] The invention relates to the technical field of hydraulic breakers, in particular to a drill rod for hydraulic breakers. Background technique [0002] The hydraulic breaker is referred to as "breaker" or "breaker". The power source of the hydraulic breaker is the pressure provided by the excavator, loader or pump station. It can break stones and rocks more effectively during engineering construction and improve work efficiency. The principle of choosing a hydraulic breaker is to choose the most suitable hydraulic breaker according to the model of the excavator and the working environment. The drill rod of the existing hydraulic breaker is often formed integrally with steel, causing unnecessary waste during use. How to design a new type of drill rod for hydraulic breakers is an urgent problem to be solved in the industry. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned p...
