Vorrichtung zum Abtragen der in Sickerbecken von Wassergewinnungsanlagen sich ablagernden Sinkstoffe

摘要

A machine for removing sedimentary material from filter beds of water supply installations. The machine has a chassis running on endless tracks and supporting a displaceable front frame carrying an inclined elevated conveyor arrangement with a plurality of circulated buckets. A rotatable drum with projecting paddles or bars serves to project material in a trough which feeds the buckets of the inclined conveyor arrangement. An inclined plate also carried by the frame serves to skim a layer of material from the bed as the machine advances and the drum picks up the material from the plate. A further conveyor extends transversally of the chassis and receives material from the inclined conveyor for subsequent discharge from the machine.
