Abstract: A method for the operation of a combine harvester includes processing a harvested material flow by at least one axial separator and ejecting a residual material flow formed in this way from the combine harvester by at least two ejection devices. The axial separator is formed by a movable vane element by means of which the residual material flow exiting from the axial separator is distributed on a work member downstream of the axial separator. In order to further improve the distribution of the residual material flow on the field, an actual distribution of the residual material flow on the two ejection devices is detected, wherein, when a deviation of the actual distribution from a predetermined reference distribution is detected, the vane element is readjusted so that the actual distribution is at least approximated to the reference distribution.

Abstract: A separating device for a combine harvester that operates according to the principle of axial flow includes a housing with a separating grate arrangement and a cover arrangement that jointly form a hollow cylinder. A separating rotor is accommodated in the hollow cylinder in a rotatably supported manner such that an intermediate space (Z1) is defined between the housing and the separating rotor for conveying crop circumferentially and along a longitudinal axis (LA) of the separating rotor. Crop stream engagement means provided on an inner surface of the cover arrangement facing the separating rotor engages radially, in a ramp-type manner around the circumference of the separating rotor, into a crop stream that circulates in the intermediate space. The crop stream engagement means are adjustable to change a radial engagement depth. Drive means connected to the crop stream engagement means are activated from outside the housing to drive the adjustment.

Abstract: A combine harvester operates with an axial separating device for separating a crop flow picked up by the combine harvester into a plurality of partial flows. A partial flow composed of grain and non-grain components is fed by a separation surface of the axial separating device to a cleaning unit disposed downstream. The axial separating device is configured to manipulate a local concentration gradient of the partial flow that is output by the axial separating device caused by a tilt of the combine harvester. The extent of the manipulation is controlled individually depending on the tilt of the combine harvester.
