Features:
1. Small size, light weight and easy installation.
2. It consists of three major parts, the main machine, the pump station, and the operation console.
3. It can be put into production in the original transportation and exploration roadway, which plays a role in protecting the
overall structure of the mine. It can also be used for surface 0-90 degree drilling.
4. The drilling rig is arranged flexibly, and the drill pipe can be twisted and unloaded mechanized, which reduces the labor
intensity of workers and improves work efficiency.
5. The drilling rig adopts box feed frame, the gripper is tightened, the power head rotates for drilling, and the oil cylinder
pulls the drilling tool, which can save the heavy drilling tower.
6. With linkage function, centralized control through the operation console, simple and safe, and stepless speed regulation.
7. Hollow shaft design, the length of the drill pipe is not limited by the given stroke of the drill. It can drill at any
inclination angle of 360°.
8. Good disintegration, convenient relocation and transportation. φ43-φ55.5-φ71 drill pipes can be used in the same machine, and the replacement only takes 15 minutes.
9. Centralized console for oil pump, water pump and power supply.
10. The pull-out column is suitable for roadways with different heights. There are two kinds of columns: 1.8m-3m and 3m-4.5m.
11. The drill pipe is made of China advanced materials, processed with high precision and quenched to increase the service life of the drill pipe.
12. The 60 mm hole and 75 mm hole can obtain 360 degree wireline coring, the working efficiency is nearly twice that of ordinary double pipe, and the manual strength is reduced.
13. The imported oil gauge line can bear high and soft pressure, reduce the impulse of high-pressure oil pulse, make the pointer of hydraulic oil gauge more stable, and timely find the changes of stratum and rock in the hole.
14. Special customized oil temperature cooler and copper pipe in oil tank, fast cooling of high-pressure oil and low-temperature use, which can protect the service life of motor, oil pump and rubber seal.
15. The drill rig can be equipped with crawler.
16. Two people in a shift can operate skillfully in 2-5 days.
