KQZ-70D Air Pressure and Electricity Joint-action DTH Drilling Rig
The brief introductions of KQZ-70Dair and electric drilling machine
KQZ-70DDTH drilling rig is a new type of high efficient drilling rock equipment designed for water conservancy projects and construction sites. It is widely used for drilling in all kinds of rock strata in open pit, water conservancy and construction slope treatment.
The KQZ-70D DTH drilling rig is a percussive rotary drilling rig. Its internal structure is different from that of a general jackdrill. Its valve train and reciprocating piston mechanism are independent, that isimpactor.
