The integrated surface DTH drilling rig can drilling vertical, inclined and horizontal holes, mainly used for open-pit mine, stonework blast holes and pre-splitting holes. It is driven by the Cummins diesel engine and the two-terminal output can drive the screw compression system and hydraulic transmission system. The drill rig is equipped with the automatic rod handling system, drilling rod floating slide module, drill pipe lubrication module, drill pipe sticking prevention system, hydraulic dry dust collection system, air conditioning cab, optional drilling angle and depth indication function, etc. The drill rig is characterized by excellent integrity, high automation, efficient drilling, environment-friendliness, energy conservation, simple operation, flexibility and travelling safety, etc
