AI Technical Summary

Technical Problem

When drilling through rock and soil layers, existing geological exploration drilling equipment suffers severe wear on the drill bit due to friction with debris, affecting its service life and drilling efficiency.

Method used

The drill bit adopts a reciprocating vibration structure, which uses a conveying ring and a conical ring to transport crushed stone to the ground, reducing drill bit friction and improving drilling efficiency.

Benefits of technology

It reduces drill bit wear, improves drilling efficiency, facilitates the sampling of crushed stone samples, and enhances the practicality of the equipment.
