Mining hard rock portable borehole drilling mahine

GD series drilling machine 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. Besides, borehole drilling rig can drill hole in the vertical and horizontal direction.

Down the hole drilling equipment is mainly used to drill blasting holes like small to medium mining projects, national defense projects, irrigation projects, road construction and etc. And it is also the indispensable drilling equipment open-air mine drilling for open pit mining in early stage, especially suitable for rugged terrain where other drilling rig can’t operate normally.

It has the below obvious feature:

Compact structure;

Convenient operation;

High efficiency;

Good detachability for easy moving.
