DTH drilling

 Drilling machine equipment development to the present through a long process, the formation of many free, some of these categories according to use different, some are classified according to the different ways of working. Among them, the drill hole is the most critical one category, but that is due to the limited use of such equipment, a lot of people have strangeness, but I believe that by introducing small-scale drilling equipment plant experts you'll eliminate some strangeness: Drilling machines a hollow shaft (hollow drill pipe), mud (discharge pumps), power head (gearbox) and mud pump discharge pipe, which is connected to the upper end of the hollow shaft power head and lower mud pump disposed within the hollow shaft side, the lower end of the discharge pipe mud pump and mud pump is connected to an outlet. To achieve a boom automatic positioning, saving on-site marking and positioning time, improve the working efficiency, so the operator can concentrate on monitoring the process of drilling. At the same time, pay more attention to environmental protection and the improvement of safety and human relations. The impact of high-speed rotation in the hole, it is by individual Rotary, that is, from the outside of the hole or pneumatic rotary motor means connected to the impact by the rear end of the drill pipe to achieve. Rock dust generated during drilling, a mixture of Feng Shui gas flushed out of the hole, carpet mixed gas is injected from the discharge pink organizations impactor drill through the center, and then the gas tank on the impactor cylinder into the bottom of the hole. DTH drilling rotary drilling rig is impact, its internal structure and general drilling machine is different, the valve and piston reciprocating mechanism is independent, that is, the impactor. Its front end directly coupled drill, drill pipe connection to the backend. When drilling impactor latent manhole, through valve means (valve), so (the hammer) the impact of the reciprocating piston inside against the solder tail, making rock drill an impact on the bottom of the hole.
