ABSTRACT:
An apparatus is provided for receiving, separating, distributing, and conveying mixture of materials, such as a mixture of grain, straw and chaff, in a manner that separates small particles of one kind, such as grain, from the rest of the mixture. Inner and outer co-axially aligned cylinders are mounted about a central longitudinally extending drive shaft. The inner cylinder has a generally solid wall and the outer cylinder is foraminous with a plurality of spiral guides mounted on its interior and exterior surfaces. A plurality of discs are mounted at spaced intervals along the shaft within the inner cylinder with the plane of each disc oriented at a non-right angle with respect to the axis of the shaft. A ring is mounted on the periphery of each disc and is adapted for rotation relative thereto. Tines project at circumferentially spaced locations from each ring through elongated apertures in the inner cylinder into the annular space defined between the exterior of the inner cylinder and the interior of the outer cylinder. The drive shaft may be rotated by a suitable drive means and the inner and outer cylinders may also be rotated in the same or opposite directions by the same or different drive means. In operation, the material, such as a mixture of grain, straw and chaff, is fed into the annular space between the inner and outer cylinders and conveyed axially therealong between the two cylinders where it is agitated by the projecting tines whereby the grain particles fall through the holes in the foraminous outer cylinder and whereby the chaff and straw are retained within the outer cylinder until they are discharged from the cylinder at the end opposite the feed end. The grain particles passing through the foraminous cylinder are collected in a suitable collecting trough which is spaced from, and partially or completely encloses, the outer cylinder.
