ABSTRACT:
An apparatus for unloading bulk material from a storage space includes an upward conveyor (14), in particular a screw conveyor. For scraping the bulk material to the inlet end (22) of the upward conveyor (14), there is a scraper conveyor (27, 28) which is pivotally movable up and down and is telescopically extensible. The scraper conveyor is pivotally connected to a protective tube (24) which is rotatable and extends about the upward conveyor (14). The protective tube is located within a pressure-absorbing pipe which prevents the bulk material from impeding the rotational movement of the protective tube. This arrangement makes it possible for the scraper conveyor to remove bulk material from different regions of the storage space, including corners.
