In the 2nd century BC, China has used manpower and used bamboo bow elastic force to make the cone drill bit impact the ground to drill. Later, it was used in rural China for a long time. It was not...
Working principle
Rock drills work according to the principle of impact crushing. During operation, the piston undergoes high-frequency reciprocating motion, continuously impacting the drill tail...
The air-leg rock drill relies on compressed air to drive the piston to reciprocate. During the stroke, the piston strikes the shank tail, and during the return stroke, the piston drives the drill t...
The rock drill works according to the principle of impact crushing.
When working, the piston makes high-frequency reciprocating motion, constantly impacting the shank.
Under the action of the impac...
