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.
