1. DTH Drilling Meaning Dth drilling machine are impact rotary blast hole drill. Mining drill rigs uses the impactor and drill bit that dive into the bottom of the hole to impact and crush the rock, so it is called a down-the-hole mining drilling machine. DTH drill machine is composed of impactor and drill bit, rotary mechanism, lifting mechanism, pressurizing device, traveling mechanism, slag discharge system, drilling frame and drill pipe. The drilling tools of the surface drilling rig include drill pipe, DTH hammer and drill bit. The surface drill rigs uses the drill rod to drive the DTH hammer and the drill bit to rotate together, and uses the piston of the DTH hammer to impact the drill bit to break the ore rock.This dth drill rig uses the compressed air output by the screw air compressor as the power to impact rock drilling and flush the blasthole. It can be divided into integrated type and separated type mine drilling machine. The integrated type mine drilling rig is installed with the air compressor and the blast hole drilling machine, and the separated type quarry driller is separated from the air compressor. The quarry drilling machine adopts crawler walking, drilling tool rotary propulsion, drilling frame jacking compensation, and quarry drill rig leveling are all driven by hydraulic pressure.
2. Hengwang DTH Drilling Rig Hengwang's pneumatic rock drill rig are slightly superior in terms of shape design and working performance. This model is equipped with a dual-motor rotary head and a multi-way valve with adjustable rotary speed. The rotary torque can reach 2200N.m, which meets the needs of 76mm drill pipes and 130 bores. The rotation speed can reach up to 150 revolutions, which meets the needs of some customers for high-speed drilling in soft rock formations. At the same time, this blast hole drilling rig series models are equipped with engineering tracks and plunger motors as standard, which increase the leveling function, improve the climbing and cross-country performance of the equipment, and can adapt to complex terrain conditions. Vertical holes can be drilled for slopes to meet the needs of different working conditions.Compared with other rock drills, the Hengwang top hammer drill rig does not increase the impact energy loss with the lengthening of the drill pipe. It can drill deep holes with large diameters. The working noise of the dth rig is greatly reduced, the drilling speed is fast, and the degree of mechanization is high. The auxiliary operation time is less, the operation efficiency of the pit drilling machine is improved, the flexibility of the blast hole rig is good and the drilling quality is high, which greatly improves the progress of the project.
