Claim 8:
9. 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 that is excited to a longitudinal oscillation and a transverse oscillation, comprising:
one or more first sensors configured for determining grain purity, and
a control unit configured for controlling the transverse oscillation depending on at least one state, wherein the at least one state for controlling the transverse oscillation is the inclination of the combine harvester,
wherein the control unit is configured for controlling the transverse oscillation depending on at least one further state comprising the grain purity,
wherein the control unit is configured to pre-adjust to a transverse oscillation reference value depending on the inclination of the combine harvester and subsequently, depending on the at least one further state, generate a control command signal with which the transverse oscillation of the conveying and cleaning unit is adjusted so that the grain purity lies within a defined tolerance range.
