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.

Application
JRC300 reverse circulation drilling rig is a new multi-purpose, high-efficiency, environmental protection, multi-track-type rig, which uses the latest foreign gas lift reverse circulation drilling technology, rock dust can be effectively collected through a dust collector to avoid environmental pollution.You can also collect slagging cyclone separator can be used in geological prospecting department of sampling analysis.It is a geological exploration drilling, drilling wells, monitoring wells, ground source heat pump air-conditioning and other deep hole of choice for equipment.
The drilling rig can be used in a variety of compressed air on the ground hole reverse circulation drilling. The lifting system,guide compensation, drill pipe loading and unloading, rotation and feed, legs, winch, walking and other system to achieve all of the hydraulic system to significantly reduce the labor intensity and improve the efficiency and quality of construction.
