Abstract: A method and an apparatus for separating a crop flow on at least one conveying and cleaning unit, particularly a top sieve, of a combine harvester, wherein the conveying and cleaning unit is excited to a longitudinal oscillation and a transverse oscillation. The transverse oscillation is controlled depending on at least one state, wherein least one state for controlling the transverse oscillation is the inclination of the combine harvester, wherein at least one further state for controlling the transverse oscillation is the grain purity, particularly the grain purity of a main crop flow. The transverse oscillation is pre-controlled depending on the inclination of the combine harvester and fine-tuned depending on the grain purity.

Abstract: A self-propelled combine harvester has at least one tilting mechanism for the uniform distribution of a harvested material on an oscillating conveying and cleaning unit, in particular a top sieve. The tilting mechanism has elements for defining a swiveling direction of the conveying and cleaning unit which are arranged between the conveying and cleaning unit and a machine housing. The tilting mechanism has an actuator for continuous adjustment of at least one component part of the elements from an initial position to an adjusting position. The position of the at least one component part decisively defines the swiveling direction. An electric control unit controls the actuator depending on a state of the combine harvester and/or harvested material and the initial position of the at least one component part of the tilting mechanism.

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.
