    Crawler Type Blasthole Drilling Rig for Fully Mechanized Mining Face Crossing the Fault

    • Aiming at the problem of low efficiency and high labor intensity of the traditional construction method of fully mechanized mining face crossing the fault, a crawler type blasthole drilling rig suitable for fully mechanized mining face crossing the fault is developed according to the drilling requirements of fully mechanized mining face with 3 m mining height. The hydraulic system of the drilling rig is simple, easy to operate and maintain. The feeding device with impact power head adopts the mechanism of double distance and double speed, the device has advantages of high efficiency and light weight. The new luffing device can realize the large angle and large range adjustment. Feeding device, luffing device, motor pump set, oil tank, control table and other parts are integrated on the tracked vehicle body, which is compact in structure and small in volume.
