ZYJ-800/190 tunnel drilling rig for coal seam infusion and grounting and water gas explortation

the ZYJ series trestle hydraulic rotary drilling rig is applied to drilling of caving blast holes, drain holes, gas drainage hole, grouting hole, geological exploration holes and other projects holes, is an ideal drilling equipment for coal mine as well as other mines.

Compact and reasonable structure, light weight, high stability, high precision drilling;

Small footprint, suitable for underground narrow operating environment
It can also attached to the side of the road header to save space.

the post can be tightly fixed in the roadway through the lifting of cylinder of the post, and the stability of the drilling rig in the drilling process is enhanced by the bracket. and the safety performance is improved. the track of the propeller makes a structure with the post and the propeller makes a reciprocating actions along the slide rail by multi-stage cylinder. Cycloid hydraulic motor under the action of the high pressure oil drives the drilling rod and drilling bit to make the drilling through the rotating device of the output shaft.

the double sections gear pump is used to control the normal operation of the components. in order to ensure the cleanness of the oil, air filters are used for in and out oil.

the operating panel is composed of a three valve, and the oil from the power pack is conveyed to the control valve through a rubber hose and then is distributed to the hydraulic system of the drilling rig.

the operating panel is provided with a speed regulating valve, an overflow valve, a hydraulic control one-way valve, a hydraulic lock, etc., so as to ensure the safe operation of the whole system. the drilling rig can connected with the air or water to cool the system or discharge the slag.
