JRC300 Good price RC reverse circulation soil sampling drilling rig machine for rock
The reverse circulation drilling rig(rc drilling rig)upgrades and optimizes the operating table, the running parts, the hydraulic system, the propulsion beam, and the turret, with the aim of maximizing the function of the rig. The walking parts use a plunger motor, which greatly extends the life of the pneumatic down-the-hole drilling rig. In particular, the improvement of the console has been changed from the original two-person operation to one-person operation, which has improved the work efficiency and reduced the cost, fully considering the market demand.
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.
