ZDY4000LP(A) type coal mine underground crawler full hydraulic drilling rig belongs to the crawler self-propelled, high torque type drilling rig. It can be drilled regular by ordinary outer flat drill pipe, and can also be drilled by spiral drill pipe. It can be constructed across belt conveyor. It is mainly used for the construction of deep gas drainage boreholes in this coal seam and adjacent layers in coal mines. It has the characteristics of convenient relocation and large adjustment range of opening azimuth and pitch angle. Features of drilling rig 1. The main engine, pump station and console are arranged on the self-propelled crawler body, which is convenient for relocation. 2. The chuck and the clamp can cooperate to realize the mechanization of the drilling tool and reduce the labor intensity of the workers. Drill

Drill Features
1. The main engine, pump station and console are arranged on the self-propelled crawler body, which is convenient to move.
2. The chuck and the clamp can cooperate to realize the mechanization of the drilling tool and reduce the labor intensity of the workers. A variety of linkage functions are set on the drilling rig to improve work efficiency.
3. The ability of feeding and pulling-out drilling tools is large, which improves the ability of drilling rig to deal with sticking accidents.
4. Adopt double pump system, rotary parameters and feed parameters can be adjusted independently. The combination of variable oil pump and variable oil motor, the speed and torque can be adjusted steplessly in a large range, which improves the adaptability of the drilling rig.
5. The main shaft of the gyrator is a through-hole structure, and the length of the drill pipe is not limited by the feed stroke of the drill. Take out the retainer slips, which can enlarge the diameter of the through hole, so as to facilitate the lifting of the thick diameter drilling tool.
6. The hydraulic components adopt imported or domestic advanced stereotyped products, with stable performance, strong versatility and reliable quality.
