ABSTRACT:
There is disclosed a flexible, hollow, tubular member for conducting a fluid therethrough to cause the tubular member to move in a whip-like manner inside a container. The conduction of fluid therethrough causes the tubular member to move in a generally upward direction through material in the container while producing whip-like motions of the tubular member to agitate compacted portions of the material and cause the material to discharge from the container. The container may include a passageway covered by an entry/sealing means which includes a one way flap or a flexible tubular housing to permit insertion of the tubular member enclosed by a tubular housing into the container, while preventing the escape of material from the container when the tubular member/housing has been removed. Retraction of the tubular housing relative to the flexible tubular member providing a substantially exposed section of the tubular member to allow for the random, whip-like movement of the tubular member in the container. The entry/sealing means are located at various portions of the container to permit selected insertion of the housing/tubular member into the container. A portion of the tubular housing may be angled at one end thereof such that rotation of the tubular housing displaces the angled end portion within the container. In addition, the flexible tubular member may be engaged by a rotary motor to cause the tubular member to be displaced radially through 360.degree. of rotation. Air is conducted through the hollow tubular member to impart to the tubular member a whip-like motion wherein the movement of the tubular member within the container is defined by the combination of the radial displacement and the whip-like motion.
