Abstract

PURPOSE:To improve working efficiency by providing a pair of mud pressure- feed tanks to supply compressed air alternately and a hopper having an open and close function to supply there with mud by a valve means and providing a pressure tube and one way valve means for the supply of mud to the inside of a sealed casing. CONSTITUTION:The mud excavated by a bucket 34(a) is fed continuously to a hopper 42 and a mud feeding tube 43 at a pressure feed section 44 by means of pressure, and is ground by an oscillating screen 46 to make it drop into the hopper 45. And, the bottom of the hopper 45 is formed into a shape of the reverse trapezoid and is connected to the mud pressure feed tanks 49 and 50 of the pressure feed section 44 in a mud pressure feed unit 39, and the mud discharge tubes 58 and 59 is extended backward to connect to a mud pressure feed distributor 60. And, the first and the second check valves 62 and 63 are housed into one end of a sealed container 61 and the mud feeding tube 43 is connected to the other end of the container 61, and a pressure air tube 64 for compressed air penetrating of one end of the wall surface of the container 61 is mounted. Accordingly, the mud can be continuously fed to the remote area through the pressure feedimg tube by pressure.
