A machine that converts compressed air into mechanical energy to break rocks. After the compressed air passes through the air-water separation, oil mist device, and pneumatic control valve, it is divided into two paths; one path enters the front and rear chambers of the propulsion cylinder. Chamber, the axial force generated by it drives the drilling tool to advance or lift through the cylinder piston, and the other path enters the impactor through the wind and water pipe in the reducer to achieve rock drilling operations. It is mainly suitable for blasting holes or direct crushing of rocks.
