AI Technical Summary
Technical Problem
When using existing directional core sampling drills for metal mines, core samples are easily stuck in the drill bit, leading to increased sampling difficulty and reduced exploration efficiency.
Method used
An anti-jamming drill bit structure was designed. By setting grooves inside the drill rod to reduce the coefficient of friction, and by using water pumps and air pumps to create water pressure and negative pressure, supplemented by sealed bearings and solenoid valves, the core can be successfully extracted.
Benefits of technology
This technology enables core samples to be quickly removed from the drill pipe without the need for hammering, improving sampling convenience and exploration efficiency, and ensuring the smooth progress of borehole core sampling.
