JRC300 Full Hydraulic rc reverse circulation down the hole track
mounted drilling rig
The reverse circulation rig(rc drilling machine) is a
cost-effective, environmentally safe, energy-saving and efficient
split-type down-the-hole drilling rig widely used in various open
pit mines, quarries, engineering sites, etc. With a hole diameter
ranging from 90 to 110 mm, the down hole drilling rig has a low
body and a new casing design, which makes the product more stable
and aesthetically pleasing than similar machines.

Characteristics
1: Diesel engine mounted hydraulic system,all the system include
the walking,rotation,feed,lifting,Leg,lifting, compensation
system,rod change is hydraulic.
2: Reverse circulation system working together with DTH
technology,air compressor provice pressed air for impact and dust
collect.
3. During working,use the reverse circulation hammer,double
tube,pressed air enter between two tube and dust out from the inner
tube.
4. Also it’s available to positive circulation use normal drilling
tool.
5. The working system composed of feed system,guide(mast),rotary
head, compensation system, centralizer,rod exchange cystem, winding
and so on.
6. Axes pressure,feed speed,rotary speed is adjustable.
7. The walking system is a self-walking system,convient for
moving,wich could install four hydraulic leg,when load on truck,it
doesn’t need hiking up,it can load on truck directly.
8. Four hydraulic leg use for keep the balance of the drilling
during working.
Aplication
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.
