[specific embodiment] the utility model is described in further detail below in conjunction with accompanying drawing:

Referring to accompanying drawing, on walking chassis 1, be provided with slew gear 2, on slew gear 2, be provided with platform 3, on platform 3, be provided with drivers' cab 8, the diesel powered system, hydraulic system 5 and operation control system 7, be hinged with swing arm 9 on the platform 3, boom cylinder 10, be hinged with hydraulic drill rig frame 12 at swing arm 9 front ends, on swing arm 9, be provided with the hinged drilling cramp of hydraulic drill rig and face upward the oil cylinder 11 of bowing, it is hinged with drilling cramp 12 to face upward the oil cylinder 11 of bowing, drilling cramp 12 is provided with oil cylinder wire rope propulsion system 13, rotary motive power head 14, drilling rod 15, guider 16, dust extractor cover 18 and drill bit 17, the rig hydraulic part is connected with described hydraulic system 5, facing upward oil cylinder 11 back cavities of bowing links to each other with the ante-chamber of boom cylinder 10, back jib lubbing mechanism triangle Δ ABC and preceding parallel moving mechanism triangle Δ A ' B ' C ' are axis of symmetry in same plane and with the swing arm, as shown in Figure 1, preceding parallel moving mechanism triangle Δ A ' B ' C ' is installed in swing arm 9 tops, back jib lubbing mechanism Δ ABC is installed in swing arm 9 belows, back jib lubbing mechanism triangle Δ ABC is similar all the time with preceding parallel moving mechanism triangle Δ A ' B ' C ', and back jib lubbing mechanism triangle Δ ABC and preceding parallel moving mechanism triangle Δ A ' B ' C ' form error free parallel moving mechanism jointly.Be provided with the air compressor machine dreg removing system 6 that is connected with described dust extractor cover 18 at platform 3.
