Abstract
A cleaning element for a combine harvester having a plurality of cleaning element frames pivotable about parallel longitudinal axes. Each of the cleaning elements has a plurality of pivotal louvers connected to a longitudinal actuating element extending coaxially through the longitudinal pivoting axis of the cleaning frame. A ball joint connects the actuating element with an actuator so that pivoting of the louvers is accomplished independent of the pivoting of the cleaning element frame.
