Air Driven DTH Drilling Machine Dia 50 - 90mm Portable SKQ70 Drill Rig For Slope Support

Air driven DTH drilling machine dia 50-90mm portable SKQ70 drill rig for slope support

This drilling rig uses compressed air as power source. The power for drill tools rotary is from pneumatic motor, Torque of the pneumatic and impact force of the hammer are from compressed air. When pneumatic motor in working condition, it changes the compressed air into rotary torque transmit to the reducer ,makes the drill rod on the output shaft of the reducer rotated.

The alloy bit in the front of the hammer impact and crush rock constantly. The high pressure compressed air discharged the drilling cuttings from drill bit exhaust vent to the ground. The shaft force from the propulsion cylinder feeding drill tools to drill hole, then draw back the drill tools.

Application

SKQ70 pneumatic DTH drilling rig is designed for these highway, railway, water conservancy, mine construction engineers which road inconvenient in the earlier projects stage.

It is suitable for the slope support and other projects. So the machine is a kind of portable and economic models.

Structure and usage

KSQ70 DTH drill rig is consist of supporting mechanism ,speed reducer,pneumatic motor,propulsion mechanism ,drilling system,atomized lubricator and pneumatic control valve.

supporting mechanism

supporting mechanism includes mast and support leg. The mast is welded from box iron. It is not only the sliding rail for the sliding plate, but also the crossbeam of the drilling rig.

Sliding plate, air cylinder and hammer holder is installed on the mast. Speed reducer slides back and forth following with the sliding plate on the mast. The supporting part is used to support mast. The inclination angle of the mast can be controlled by adjusting the length of rear support legs, then changing the angle of drill hole.

Performance advantages:
1. Safe and stable traveling system
Low gravity, great ground clearance, make cars easily make drill through rugged road.The advanced automatic balance system, not only makes drilling stable, also greatly reduced the impact of the car, and ensure the safe driving.
2. Centralized operating system of Mobile Drilling Rig Drill carriage designed with advanced hydraulic system and completely functional gas circuit system.
3. Powerful feeding and rotating system of Mobile Drilling Rig
Promote reducer drives adopt turbine and worm, which have a big push- pull effort and can reliaze self-locking.
4. Adjustable boom
Adopt adjustable boom, the dip angle of hole and Level hole height can adjust by control the oil tank stretch out and draw back.
