Abstract
A clean grain evacuation device for a grain harvester having a threshing system configured to separate grain harvested by the harvester from crop residue and direct a flow of the grain to a cleaning system disposed within the harvester including at least two sieves disposed and configured to sequentially clean the grain. The evacuation device is disposed for receiving a portion of the flow of the clean grain from a first of the sieves, and is configured to evacuate the received clean grain away from the cleaning system. The evacuation device can include a conveyor disposed for directing the evacuated grain directly to a desired location such as a clean grain receiving system on the harvester. The evacuation device can also be located in an air flow path to the sieves.
