KQZ-100 pneumatic DTH drilling rig
1.Brief introductions of KQZ-100 pneumatic DTH drilling rig
KQZ-100 pneumatic DTH drilling rig is a new type of high efficient
rock drilling equipment designed for water conservancy projects and
building materials sites. It is widely used for drilling in all
kinds of rock stratum and drill hole. For example, water
conservancy and construction slope treatment .
KQZ-100 pneumatic DTH drilling rig is an impact rotary drilling
rig. Its internal structure is different from the general drilling
machine. Its gas distribution and piston reciprocating mechanism
are independent with each other. The front end is directly
connected to the bit, and the back end is connected to the drill
pipe. When driving the hole, the impactor will rotate in the hole.
The piston (hammer body) in the impactor is made reciprocating to
strike the drill tail through the valve, making the drill produce a
kind of gyration force to the rock bottom.
2. Features of KQZ-100 pneumatic DTH drilling rig
Small volume, light weight, suitable for large and medium-sized
drilling rig can not workplace, convenient and flexible.
