RC Mining Drilling Rig Equipment Machine

    An RC drill rig, short for Reverse Circulation drill rig, is a specialized drilling machine that uses compressed air to lift rock cuttings from the drill hole through a reverse air flow system. Unlike traditional drilling methods, the RC drill rig employs a dual-walled drill pipe: air flows down the outer pipe and cuttings are returned up through the inner pipe, ensuring rapid and uncontaminated sample retrieval.


Introduction of Rc Mining Drilling Rig 

Introduction to RC Full - hydraulic Air Reverse Circulation Drill Rig:
The reverse circulation drilling rig adopts a crawler chassis loading, diesel power configuration and a fully hydraulic drive mode.
The rotary power head is driven by a hydraulic motor and achieves two-speed change of high and low through oil circuit switching.
The power head has the functions of lateral movement to open the hole opening and forward tilting to flip (up to 40 degrees).
The feeding mechanism adopts a double-cylinder direct push type and is embedded in the mast.
The hole opening device (hydraulic clamp type) is installed together with the power head on the mast and can drill inclined and vertical holes.
A hydraulic pipe tightening machine mechanism can also be added to the orifice.
The power is provided by a Cummins 6BTA diesel engine and is equipped with a high-pressure three-pump.
The hydraulic operating system adopts an open system, with multiple sets of multi-way valves arranged in zones.
The outriggers can be extended outward for extension and retraction.
Set up the winch for lifting tools.
