Track type dive hole rig job Shi can place do overall rotary movement, take soil Shi, relies on with drill pipe and bit weight cut soil, oblique to bucket tooth in drill bucket Rotary of when cut Xia clods to bucket within advance and completed drill take soil; met hard soil of when, weight force insufficient of when is to makes bucket tooth cut soil, at can through pressure oil cylinder on drill pipe pressure, forced of will bucket tooth cut soil in the, completed drilling take soil. Fill the bucket of soil from crane lifting drill pipe and drill into the ground, pull the bucket can open doors at the end of the switching on, bucket of Earth relies on gravity discharge the decentralization of drill pipe to aggressive door is closed, and then return to the next bucket of mining hole. Hole should be continuous without interruption.

Above is the presentation on crawler DTH drill rig, hoping to give you some idea.
