Abstract

See full text

A spreader for a harvesting machine includes a pair of counter-rotating spreader units each having an impeller and a fan supported on a common shaft. A plenum routes at least part of the airflow from a first fan to merge with chaff exiting the opposite impeller and at least a part of the airflow from the opposite fan to merge with chaff exiting the impeller on the machine side of the first fan. In one embodiment all airflow from a fan is ducted to an impeller on the opposite side, while a second embodiment commingles airflow from both fans in a plenum from which portions of the mixed airflows is directed to the chaff exiting each impeller exit. In a third, embodiment an established airflow receives chaff from the impeller on the side on which that airflow is generated.
