Abstract
An auger housing assembly for converging material along a path has a conduit within which is located a rotary auger. The conduit has at its lower side an elongate slot through which it may pass. Such slot normally is closed by a split sleeve member carried by the conduit and which is rotatable from a first position in which it covers the slot to a second position in which the slot is uncovered.
Claims7
Apparatus for feeding material along a conduit having an inlet, and an outlet at a discharge end axially spaced from said inlet;
- a rotary auger extending along said conduit adjacent its bottom for moving material along said conduit toward the outlet at its discharge end, said bottom of said conduit having an uninterrupted, elongate slot therein extending axially of said conduit and through which material from said conduit may pass;
- a cover member;
- and means mounting said cover member on said conduit for rotary and axial movements relative to said conduit, said cover member having an uninterrupted passage therein extending the entire length of said cover and through which material discharged through said slot may pass when said cover is rotatably adjusted to a position in which said passage registers with said slot, said cover having a length greater than that of said slot thereby enabling said cover to be extended axially beyond the discharge end of said conduit and effectively extend the length of said conduit when said cover occupies a position in which said passage is out of register with said slot.
