AI Technical Summary
During operation, the bottom and sides of the drill bit overheat due to friction with the rock, which affects work efficiency and requires frequent stops to cool down.
A heat dissipation pipe is installed on the inner wall of the drill body and connected to a water storage tank. Water is injected through the connection port for heat dissipation. A feed chute is opened on the outer side of the drill body to discharge stone material. Combined with the first and second drain outlets, all-round heat dissipation is achieved.
It effectively solves the problem of overheating caused by friction in the tubular drill, improves work continuity and efficiency, and avoids difficulties in movement caused by stone accumulation.
