INTEGRATED DRILLING UNIT FOR DRILLING WITH WATER DRAINAGE FOR ANCHOR SOLES PRODUCTION Russian patent published in 2017 - IPC E21B21/00 E21D20/00 

FIELD: mining.

SUBSTANCE: device comprises a cylinder (7) of the charge air, the engine (8), the lever (9), the control knob (11), torque and the muffler (12). The front end of the motor (8) is connected with a mechanism (17) of the optimum water circulation via a regulator (11) of torque. The mechanism (17) comprises a water circulation optimal transmission shaft and filtered water circulation pump mounted on the coupling by means of the transmission shaft. The circulation pump comprises a filtered water conduit (3) collecting the rock powder. Filter mesh is installed on one side of the box (3) for collecting the rock powder. Suction and pressure pump is mounted under the filter mesh. Channel of pure water, which communicates with the release of the suction and pressure pump, is mounted on the other side of the box (3) for collecting the rock powder. Hole of external water pipe is installed on site channel inlet for pure water. The front end of the transmission shaft is provided with an internal annular groove, the inner wall of which is provided with inlet openings for clean water. The rear end of the transmission shaft is provided with a cylindrical inner recess, the inner wall of which is provided with waste water-absorbing holes. Suction and pressure pump pumps the slurry into the storm bore and produces sludge in the sludge chamber through the drain hole of absorbing water. The separated water is pumped into the duct for clean water for reuse.

EFFECT: water resource is saved, as well as the rock powder in a storm hole is promptly collected, improving drilling efficiency.
