JRC300 Multi-purpose hydraulic DTH crawler reverse circulation RC drilling machine


RC drilling obtains cuttings samples, not cores. The principle of drilling is to use a pneumatic hammer to drive a tungsten steel drill bit to break the rock formation. A pneumatic reciprocating piston repeatedly called a hammer, which in turn drives a tungsten steel drill bit that is used to break hard rock. When the compressed air is blown out, the pressure deviation will produce a reverse circulation, so that the cuttings will enter the inner tube upward. When the cuttings reach the ground, they are connected to the cyclone separator through a hose for sample reduction, and then the sample falls into the sample bag from the bottom opening. These sample bags are marked with the location and depth of the collected samples and can be transported directly to the laboratory for analysis.
