ABSTRACT:
A rotary grain distribution system includes a distributor having a grain filling chute and an air exhausting chute rotatably positioned within a housing and each terminating at one end in an annular cover and indexing ring. The indexing ring is positioned in proximity with the open ends of a plurality of chutes extending from the lower end of the distributor to grain storage bins below for selectively coupling the grain filling and exhaust chutes to one of a plurality of storage bins while sealing off the remaining bins. A ratchet and pawl drive mechanism coupled between the housing and the indexing ring provides a positive drive for accurately aligning the indexing ring and grain and exhaust chutes to the chutes extending to the storage bins. A cyclone precipitator has an intake coupled to the exhausting chute for evacuating air from a grain bin as it is being filled and collecting and returning the particulate matter to the supply of grain.
