EARTH DRILL SYSTEM
Document Type and Number:
Japanese Patent JP3225309
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To discharge chips and water continuously and to collect the chips without leaving in a drilled hole or a pipe.
SOLUTION: A drill cutter 31 at a drill cutter mechanism section 5 is turned by means of a high output hydraulic motor 4 to drill an object. A thrust mechanism imparts a thrust to a thrust shaft 3 thus thrusting the drill cutter mechanism section 5 and high output hydraulic motor 4. Drill chips are delivered rearward by the water flow from high output hydraulic motor 4 and sucked utilizing a negative pressure produced by a jet flow accelerated through a jet pump 6A before being delivered by increasing the pressure.
