ZDY4000L crawler type full hydraulic drilling machine product structure：
The tunnel drilling rig of ZDY4000L coal mine adopts integral arrangement. The whole machine consists of four parts: main engine, pump station, control console and crawler body. The parts are connected by hoses. The structure is compact and easy to relocate and transport. Area.
The full hydraulic drilling rig is mainly used for drilling gas drainage holes, drainage holes, grouting fire extinguishing holes, coal seam water injection holes, outburst relief holes, geological exploration holes and other engineering holes.
It is applicable to all kinds of coal and rock strata with rock firmness coefficient f ≤ 10. It is required that the section of roadway and drilling field shall be greater than 6.5 ㎡, height ≥ 2.5 m, and width ≥ 2.8 m.
The multi way reversing valve group is composed of five valves, which respectively control the forward and reverse rotation of the power head, the forward and backward movement of the normal amount of the feed oil, the fast forward and backward movement, the clamping or loosening of the hydraulic chuck and the gripper, and the inclination adjustment of the drilling rig. When the drill is working, the feed speed of the drill can be changed by adjusting the handle of the throttle valve (fine adjustment) to change the flow of the feed cylinder.
All products strive to provide the highest operation efficiency with the lowest maintenance cost.The console is mainly composed of the bench, multi-channel reversing valve group, throttle valve, pressure gauge, rubber hose, quick change connector, etc.
The console is used to distribute the pressure oil provided by the pump station to each hydraulic actuating element through the multi way directional valve group to realize various functions of the drilling rig.
