DTH drilling rig and impactor QC70/80/90 series impactor is developed by our company on the base of the defect of stuck situation occurred to tradiontal products. It matches the linker, conictiy, reducing to the whole, and can be used in energy, transportation, smelting and construction material production industry for drilling. These new machine's design can reduce the users' expense in two aspects. First, the design of trinity can link the drill directly to reduce the users' cost. Second, when it is blocked and need to be lifted, the design of the drill can lessen the nowelwhat decrease the accidents. When the machine is working, to protect the powder from cantaminating the parts, the machine also applies special craft of micro programmed control tempering. What is for adding a little high-pressure water to the compressed air to wet the stock for the workers' health.
