There's a bomb in front of you. It asks you to use a wide range of DTH Drill. Do you know? The dive drill can be used to drill the rock anchor hole, bolt hole, blasting hole and grouting hole in the construction of urban construction, railway, highway, river and hydropower project.
Wide use of submersible drill
The DTH Drill is driven by a motor through a high performance reducer, and the cylinder is used as propulsion power. The hydraulic system is omitted, so the mechanical efficiency is high, the cost is low, and the performance is stable. It has anti card protection. When the drilling tool is stuck, the motor is not easy to burn down and the reducer is not easy to damage. Light and easy to move, the weight of the DTH Drill is less than 500Kg, and it can be decomposed into three pieces. The rolling trailer is used, and the track is not easy to wear. The downhole drill adopts semi-automatic dismantling drill pipe and has high efficiency.
The DTH drilling tool consists of drill pipe, ball bit and impactor. When drilling, two drill rods are used to drill the rod. The rotary air supply mechanism is composed of a rotary motor, a rotary reducer and an air supply gyration device.
