overview

The reverse circulation series multi-functional drilling rig is a new, efficient, environmentally friendly and multi-functional crawler drilling rig. It adopts the latest foreign RC drilling technology and uses a double-wall drill pipe. After the slag is discharged from the inner tube, it is collected through a cyclone collector. The slag can be used for sampling and analysis work in the geological exploration department. It is the preferred equipment for geological exploration sampling drilling.

Features of the reverse circulation drilling rig

1. High-performance reverse circulation impactor down-the-hole operation The air compressor supplies air and slag discharge, and can be equipped with various impactors and drill bits according to the size of the working hole.

2. Adopt standard modular design Each series of drilling rig modules can be installed on a crawler chassis or truck, making them easy to move.

3. The rotation of the drilling rig adopts the motor of an American wholly-owned enterprise. Two-point drive, low failure rate, small model and large torque. The rotation speed can be adjusted according to different working conditions, effectively improving the impactor footage efficiency.

4. Drilling and lifting adopt oil cylinder plate chain structure, which is safe and reliable. The drilling axial pressure and drilling speed can also be adjusted according to different working conditions, effectively improving the impactor footage efficiency.

5. The hydraulic system is equipped with an independent hydraulic oil radiator Ensure that the drilling rig can work continuously under outdoor high-temperature climate conditions.

6. Multifunctional hydraulic jack The drilling rig can be leveled when working and can be loaded and unloaded by itself during transportation, without the need for hoisting.
