EARTH-AND-SAND AGITATING APPARATUS USING HIGH PRESSURE WATER, FOR EARTH-AND-SAND FORCE-FEEDING MACHINE
Document Type and Number:
Japanese Patent JP3650589
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide an earth-and-sand agitating apparatus using high pressure water, for an earth-and-sand force feeding machine, which can stably force-feed earth and sand by improving or maintaining the fluidity of the earth and sand charged in a hopper of the piston-type earth-and-sand force-feeding machine.
SOLUTION: According to the earth-and-sand force-feeding machine, a piston is withdrawn from the hopper portion into which earth and sand are charged, and the earth and sand are sucked into a cylinder, followed by connecting an opening of the cylinder to a discharge pipe by a valve switching means, to thereby force-feed the earth and sand by the piston. The earth-and-sand force-feeding machine has a water feeding pipe at a bottom of the hopper portion, and a predetermined quantity of water is injected into the hopper portion to agitate the earth and sand.
