The Rock Drill works according to the principle of impact crushing.When working, the piston makes high frequency reciprocating motion, continuously impinge the drill bit tail.Under the action of impact force, the rock is crushed and cut into a certain depth by a wedge shaped drill head, forming a concave mark.When the piston returns, the solder rotates at a certain Angle, and the piston moves forward.The fan shaped block between the two notches is sheared by the horizontal force produced by the drill head.The piston continuously impinges on the end of the drill and continuously inputs compressed air or pressure water from the core hole of the drill to discharge the rock slag out of the hole, which is to form a circular hole with a certain depth Pneumatic Rock Drill,Pneumatic Rock Hammer Drill,Pneumatic Manual Rock Drill,Pneumatic Air Rock Drill Jining Dongda Electromechanical Co.,Ltd. , http://www.coal-mine-equipment.com
