Geological Core Exploration Drill Rigs With Mechanical Transmission
Description:
Our GXY-2B core drilling machine is a kind of vertical shaft rotary drill rig that is designed with mechanical transmission and hydraulic feeding mode. And it is mainly applicable to engineering geological investigation, general survey and exploration of solid deposits, dam grouting, and ventilating and draining of tunnel.
According to different strata (ground), the drilling bit of the core drilling machine can be types of tungsten carbide, steel grit, spiral, etc. And the trough-hole of vertical shaft is 8.
Advantages:
1. More suitable rotating speed and bigger torque have been designed for its vertical shaft.
2. More rational range of rotating speed is available, and its rotating speed has 8 grades.
3. Centralized speed adjusting, mutual self locking and low-speed torque are utilized for this kind of core drilling rig.
4. Two different kinds of reverse speeds make it easy to deal with different machine faults.
5. Self-centering hydraulic chuck makes it convenient to clamp and loosen drill rods.
6. The oil-pressure feed mechanism has strengthened its pressurizing and lifting capacity.
7. Enough instruments (or meters) are used to get enough information about the situations of holes.
8. Less manipulation (control) handles have been equipped for this core drilling rig.
9. Dual normally closed friction clutch is flexible to close, open, adjust and operate.
10. Being light, compact-structured and convenient to disassemble, this kind of GXY-2B core drilling machine is quite suitable for drilling work in hilly or mountainous areas.
