Abstract:
An apparatus for directing granular material through a container, said apparatus comprising:a converging transition portion defining an input opening which converges to an output opening, said output opening having a first transverse opening dimension (x1); an elongated chimney portion coupled to said converging transition portion adjacent said output opening, said elongated chimney portion having a second transverse opening dimension (x2), said first transverse opening dimension (x1) being smaller than said second transverse opening dimension (x2), whereby as the granular material passes through said output opening having said first transverse opening dimension (x1) into said elongated chimney portion having said second transverse opening dimension (x2), relief of outward pressures created in the converging transition portion is provided to minimize bridging of the granular material within the container; and a rotatable coupling mechanism disposed between said converging transition portion and said elongated chimney portion, said rotatable coupling mechanism operable to enable 360Â° rotation of said elongated chimney portion relative to the container to adjustably direct said granular material out of the container.
