Self-propelled pickup device for picking up materials lying on the bottom of the sea

摘要: The device comprises an undercarriage extending transversely of the working direction device, and supported, at its opposite ends, by respective pairs worms with each pair rotating in directions. A cantilever bracket is mounted on forward side undercarriage, considered direction. plurality conveyor troughs are mounted, for pivoting about a horizontal axis, edge hydraulic actuators connected between trough bracket, so that troughs, which inclined rearwardly upwardly, may be adjusted respect to their angular orientation. Struts from connect third driving unit comprise either oppositely having axes or two laterally spaced worms. endless scraper chain extends along trough, has cutting tool lower end. At upper rearward end cut material discharged into conveyors convey upwardly belt covered cover belt. delivers classifying screen above there arranged pressure water supply. undesired drops through while desired slides over hopper leading elevator. several provide essentially three-point support device.
