Abstract
An apparatus for removing relatively dense particulate or viscous sedimentary waste material from a storage container, transporting the material to a selected location, and depositing the material at that location in a selected manner. A wheeled carriage supports a rotatably mounted elongate holding tank having an axis of rotation parallel to the axes of rotation of the carriage wheels and an elongate aperture extending from end to end thereof. A cover having an inlet for feeding waste material into the tank and an outlet connected to a vacuum pump for reducing air pressure within the tank is supported by a pair of upright standards such that the cover may be sealingly pressed against the tank over its aperture when the aperture is oriented to open upwardly, or lifted up away from the tank to permit the tank to be rotated once it is full. A crank, connected to the tank by a chain, enables the tank to be rotated to place the aperture in any angular position for emptying the tank, thereby enabling the material within the tank to be controllably emptied through the aperture and to be entirely removed from the tank. A baffle placed along one side of the tank directs waste material down…
