ABSTRACT:
A rotary conveyor includes a cylindrical housing forming part of a centering auger having opposite ends respectively mounted for in a pair of supports for rotation about a horizontal axis. A finger assembly is mounted in a central portion of the housing between auger flighting secured to opposite end portions of the housing. The finger assembly includes a crankshaft having a cranked central portion that is eccentric to and located in the central portion of the housing. Fingers are mounted for pivoting about the cranked central portion of the crankshaft and are slidably received in openings provided in the housing. Opposite ends of the crankshaft are supported in the pair of supports for rotating about said horizontal axis. One end portion of the crankshaft extends through one of the supports and has a retainer fixed thereto. A flange is releasably fixed to the one support just inwardly of the retainer and carries a rib extending arcuately about the crankshaft and having opposite ends defining a pair stops located in the path of movement of the retainer. Resistance of crop engaged by the end sections of the fingers projecting through the openings in the housing causes the crankshaft to be rotated to move the retainer from one stop to the other when the direction of rotation of the housing is reversed, as when a jam occurs in the flow of crop material through the conveyor.
