The Working Principle of Rock Drill Machine

The rock drill machine's work adhere to the principle of impact crushing. When the high frequency piston reciprocating motion, continue to impact drill tail. The impact force under the action of a wedge shaped rock bit will be crushed and a certain depth into the chisel, forming a dent. 

After the piston back, drill rod rotates a certain angle, the piston moves forward, once again the impact of shank, and the formation of a new dent. Horizontal component of fan rock between two dent is by bit on the shear broken. Piston continually impacting drill tail, and from the center hole of the drill rod continuous input compressed air or pressure water, rock slag discharging hole, that is, the formation of a certain depth of a circular borehole
