PUMP WATER WELL DRILLING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a pump water well drilling machine which absorbs sediment by wind pressure.;SOLUTION: A pump water well drilling machine includes a screw socket 1, a pipe 2, a sediment receiving part 3, a sediment excavation metal fitting 4, and an air discharge port 5. When wind pressure from an exhaust port of an internal combustion engine of a vehicle, for example, is supplied to the machine by use of a hose, the wind pressure from the air discharge port 5 pushes up the sediment loosened by the sediment excavation metal fitting 4 into water, to store the falling sediment in the sediment receiving part 3.;COPYRIGHT: (C)2015,JPO&INPIT
