Working Principle:

GD70 electric drilling rig is the equipment that converts the electric energy and compressed air into  mechanical energy to break rock. After electrify, the drilling tool is driven by the torque produced by  cycloidal reducer through the intake seat. Compressed air are divided into two way after going through oil mist device and pneumatic valve: one way enters into the cavity of promoting cylinder, which  produces an axial force drives the drilling tool to promote or elevate through the cylinder piston and  guide rod; the other way enters into the impactor through the intake seat, so as to achieve impact  drilling.
