AI Technical Summary

Technical Problem

Traditional drilling equipment tends to exacerbate dust generation during slag removal, worsening the working environment and having limited cooling effects, thus affecting drilling efficiency and equipment stability.

Method used

The system employs a gas-water mixed spiral slag discharge structure, which gradually removes drill cuttings from the borehole through the rotation of the spiral sleeve. It also utilizes gas and water holes to provide gas and water flow for staged auxiliary movement and cooling, thus preventing dust diffusion and drill bit overheating.

Benefits of technology

It achieves efficient slag removal, dust suppression, and precise cooling, maintaining stable drill bit temperature, preventing drill bit damage and rock plasticization, and improving drilling efficiency and equipment performance.
