ABSTRACT:
The invention refers to a screen for a cleaning device of a harvester-thresher, with a screen frame, on which several screen metal sheets are supported so they can rotate around an axis, and with at least one air conducting surface, which protrudes downward beyond the screen frame, to deflect an air flow present below the screen during operation upward to the screen metal sheets. The air conducting surface may be movable jointly with the screen metal sheets.
