Working Principle
LD70 electric drilling rig is the equipment that converts the electric energy andcompressed air into mechanical energy to break rock. After electrify, the drilling tool isdriven by the torque produced by cycloidal reducer through the intake seat. Compressedair are divided into two way after going through oil mist device and pneumatic valve: oneway enters into the cavity of promoting cylinder, which produces an axial force drives thedrilling tool to promote or elevate through the cylinder piston and guide rod; the other wayenters into the impactor through the intake seat, so as to achieve impact drilling
