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.
