PURPOSE: To prevent the jet of sludge from occurring and to promote cut-off efficiency. ;CONSTITUTION: An earth-moving gate 22 provided to an earth-moving port 21 of a screw conveyer 20 seals sludge between a spherical valve 23 and a valve sheet 24. The spherical valve 23 is pushed with a spherical seat pushing jack, and it is resisted against pressure of sludge in the valve sheet 24. A space or a contact state between the surface of the spherical valve 23 and valve sheet 24 is adjusted by a spherical seat adjusting bolt, and biting of earth and sand in a sealed surface is prevented to promote cut-off efficiency.;COPYRIGHT: (C)1996,JPO
