ABSTRACT:
A bunker discharge apparatus, especially for bulk material. The apparatus includes conveyor elements having a ladder form or shape and extending parallel to each other and movable back and forth, by way of a drive, in the conveying or feeding direction. The elements include rungs or crossbars arranged transverse to the conveying direction and wedge-shaped in cross section. The crossbars have a stroke or pusher surface at right angles in the conveyor direction to shear and push bulk material to discharge; counter to the conveying direction, the crossbars have a flat-inclined wedge surface which returns to starting location with minimum displacement of bulk material. A drop-out or discharge connection or connecting piece having a conveying element and arranged at right angles is provided below the ladder-formed conveying elements. At one end, the conveying elements are connected to hydraulic cylinders arranged in pairs, and at the opposite end they are guided directly or indirectly by diverting rollers, whereby at any given time, one-hydraulic cylinder is engaged completely by a timing member providing a cycle of operation, and the other hydraulic cylinder is only partially engageable therewith. Accordingly, all push or stroke forces are convertible into pulling forces, so that the conveyor elements, in operation, are continuously under tension or pulling stress which is adjustable to advance bulk material to discharge from the apparatus.
