Further, the mute pad is detachably connected with the inner side of the shell, so that the mute pad can be detached and replaced.

Further setting, the silence strip is dismantled and connected to the casing both sides, can promote the silence effect.

Further, a window is formed in the surface of the shell, the window is covered by a small cover plate connected to the shell through screws, and one of the small cover plates penetrates through the all-rubber block, so that the noise reduction effect can be improved.

Further setting, the adapter is passed through bolted connection to casing one end, can realize adapter's adaptation, dismantlement and change.

Further, the mute pad is detachably connected between the shell and the center of the conversion head, so that the integral noise reduction effect of the crusher can be improved.

Further, the shell and the upper cylinder body are connected through a bolt in a penetrating mode, and the overall stability of the low-noise crusher can be improved.

Compared with the prior art, the utility model provides a low noise quartering hammer has following beneficial effect:

the utility model provides a low noise quartering hammer adopts through the silence quartering hammer be conservative two eccentric horizontal structure, adopts the shock attenuation of full block rubber, and under the certain circumstances of engine power, old-fashioned quartering hammer becomes the noise to some energy and has given off. While silent breakers use almost the full power of the engine on the object being crushed. And repeated stressing at very high frequencies (39 Hz) allows the target to crack itself, which is a typical four and two jack practice. High efficiency and reasonable conditions. From the construction effect, the advantage of the equipment for replacing the traditional breaking hammer is obvious. The technical problem of traditional quartering hammer noise is great is solved.
