The process begins with the rig's high-torque hydraulic motor, which delivers immense, consistent power to rotate a string of drill pipes tipped with diamond-impregnated core bits.

This hydraulic system provides superior control over rotational speed and downward pressure (feed force), allowing it to efficiently penetrate the hardest rock formations, including granite, quartzite, and deep basalt layers.

A critical feature for maintaining borehole stability and sample integrity at such depths is the use of a drilling fluid (mud) system, which cools the bit, removes cuttings, and reinforces the borehole walls.
1. with oil pressure automatic feed structure, mechanical transmission, improve drilling efficiency, reduce workers physical labor intensity.
2. using the ball card holding structure instead of chuck, can achieve non-stop rod, handle concentration, easy to operate, safe and reliable.
3. equipped with hole bottom pressure gauge to indicate the pressure, easy to grasp the situation in the hole.
4.can be used to move the hole, or open the rotary to open the hole.
5. the structure is tight, the drill, water pump and diesel engine are installed on the same base, occupying a small area.
6. light weight, strong decomposition, easy to move, suitable for plain and mountain construction.
