1.The brief introduction of KQZ-100 full pneumatic DTH Drill
KQZ-100 pneumatic down-the-hole 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 etc.
KQZ-100 pneumatic down-the-hole drilling rig is an impact rotary
drilling rig. Its internal structure is different from that of the
general drilling machine. Its gas distribution and piston
reciprocating mechanism are independent, that is, the impactor. The
front end is directly connected to the bit, and the back end is
connected to the drill pipe. when diving the hole, the impactor
drill in 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.

Small volume, light weight, suitable for large and medium-sized
drilling rig can not workplace, convenient and flexible.
