Abstract
In a combine harvester, the chaff discharged from the cleaning shoe is funneled towards the downwardly directed inlet of a pneumatic conveyor and transferred, by the conveyor, to the inlet of a rear mounted straw chopper. In this way, the relatively light chaff material is mixed with heavier straw helping to spread the chaff more widely and uniformly. The upward intake or ingestion at the conveyor inlet aerodynamically screens out undesirably heavy material, allowing it to fall to the ground.
