The invention relates to the technical field of
geological exploration, and particularly discloses an integrated air reverse circulation drilling
machine driven by an automobile engine. The drilling
machine comprises an automobile
chassis, a drilling
machine assembly, an
air compressor set and a
power output mechanism, all parts are integrally installed on a carrying frame of the automobile
chassis, an engine serves as a power source of the drilling machine and is connected with a first power
takeoff and a second power
takeoff through a
transfer case and a gearbox, and then a first hydraulic
oil pump and a second hydraulic
oil pump of the
power output mechanism are driven through a universal shaft. Hydraulic power is provided for actions of power
head rotation, pressurized lifting, mast posture adjustment and the like; the
air compressor unit and the drilling machine
assembly work cooperatively, the
cyclone separation mechanism achieves purification circulation of gas and
solid (rock debris /
rock sample) separation, and the operation mechanism completes centralized control of the operation process. Through the vehicle-mounted integrated integration and power reuse design, the transition efficiency of the drilling machine is greatly improved, the damage of the crawler belt to the
road surface is avoided, the equipment structure is simplified, and the overall weight and
energy consumption are reduced.
