Description

Technical Field

[0001] The utility model relates to the technical field of breaker hammer cores, in particular to a breaker hammer core capable of increasing striking force. Background Art

[0002] Hydraulic breaker is also known as "breaker" or "breaker". The power source of hydraulic breaker is the pressure provided by excavator, loader or pump station. It can break stones and rocks more effectively during construction and improve work efficiency.

[0003] For example, a breaker hammer movement with patent number CN211816549U includes an upper cylinder body, a sealing gasket is arranged on the top of the upper cylinder body, a cylinder cover is arranged on the top of the sealing gasket, a stepped cavity is arranged inside the upper cylinder body, a piston is arranged inside the stepped cavity, a plurality of oil paths are opened on the side wall of the stepped cavity, and the oil paths extend to the outer surface of the upper cylinder body, a connecting cylinder is connected to the bottom end of the upper cylinder body, a lower cylinder body is arranged at the bottom end of the connecting cylinder, a drill rod is arranged inside the lower cylinder body, and a limit pin is symmetrically arranged on the top of the drill rod. The above-mentioned document still has shortcomings. When in use, a balance cavity is arranged to cooperate with an airbag, so that when the piston moves to the top dead center, the piston compresses the balance cavity. The hydraulic oil in the cylinder squeezes the air bag to absorb the kinetic energy of the piston, so as to balance the piston and reduce the impact of the piston on the cylinder body. At the same time, the load of the breaker hammer movement is increased. By setting the end of the drill rod to a quadrangular pyramid structure, the quadrangular pyramid section has increased impact force and penetration force compared with the traditional cylindrical drill rod in actual use, so as to achieve better crushing effect. However, when applying force to the drill rod, if the striking position is harder, a larger pressure will be required, which has certain requirements on the driving mechanism. During use, it is not convenient to increase the striking force. At the same time, the drill rod will have certain wear during use, and it is not convenient to replace the drill rod during use.
