Abstract

The invention relates to a breaking hammer drill rod, and belongs to the technical field of breaking hammers. The breaking hammer drill rod comprises a drill rod main body, a buffer structure and a drill rod head; the drill rod main body is detachably connected with the buffer structure through bolts; and the buffer structure is detachably connected with the drill rod head through bolts. Compared with the prior art, the production cost is lowered, the breaking hammer drill rod has the excellent shock absorption effect and the service lives of various components of the breaking hammer are prolonged.

Description

technical field [0001] The invention relates to the technical field of breaking hammers, in particular to a breaking hammer chisel. Background technique [0002] The power source of the breaker is the pressure provided by the excavator, loader or pump station, which can more effectively break stones and rocks in engineering construction and improve work efficiency. The principle of choosing a breaker is to choose the most suitable breaker according to the model of the excavator and the working environment. The drill rod of the existing breaking hammer is often formed integrally with steel, causing unnecessary waste during use. How to design a new type of breaker drill rod 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 shortcomings of the above-mentioned prior art and provide a breaker drill rod. [0004] In order to achieve the above object, the present invention proposes a bre...
