KQD70 Portable DTH Rock Drill/Small Electric Water Well Drilling Machine

KQD Series are mainly used for water well drilling rig and blast hole drill, This series electric drilling
rig is to transfer the motor power and compressed air power into mechanical power for rock crushing.
When energized, the torque generated by the motor through gear reducer parts to drive the rotation of drill.
Compressed air lubricated after the pneumatic valve is divided into two roads, one is through the air valve
come into the front and back chamber of push cylinder, which produces an axial force through the cylinder
piston rod and guide rod to advance or promote the rods, another way is through the intake seat reducer
and other components into the impactor inside, so as to realize impact drilling.

The Ultimate combination of performance and economy. Our DTH system delivers the highest-possible
drilling performance at low running cost. Our DTH used in varity heavy industry. It is used to drill blasting
holes lije small to medium mining projects, national defense project, irrigation projects, road construction
and so on. Our down-the-hole drill is ideal equipment for down-hole blasting.

Advantage:
1. Forward, turn, and the impact of all the compressed air as power, structure simple, power, relocation facilities.
2. In the single-top, double top, bearing-type three supporting structures to choose fom, can adapt to any geological features.
3. Centralized control mechanism, easy to operate.
4. Unique dual muffler, muffler effect, reducing environmental pollution.
