Abstract
An apparatus for loading materials from a hopper into a storage container includes a holding chamber formed in part by a movable first panel which forms the floor of the holding chamber. Communication between the holding chamber and the hopper is opened by withdrawing the first panel, thereby allowing materials in the holding chamber to empty into the hopper. As the first panel is subsequently moved to again close communication between the holding chamber and the hopper, materials in the hopper are expelled by a wall which advances in the hopper as the first panel moves. Preferably, the first panel is repeatedly oscillated or cycled opened and closed within a predetermined time period to efficiently move large volumes of materials from the holding chamber, into the hopper, and out into the associated storage container.
