摘要：
A combine harvester is provided with a threshing system, a preparation arrangement and cleaning arrangement. The preparation arrangement comprises multiple preparation stages, each of said stages being configured to transport said mixture over a given distance between a front edge and a rear edge of the stage, with an air gap being present between each pair of consecutive stages. The preparation arrangement further comprises a blower, separate from the main blower, said blower configured to direct air towards at least one of said air gaps, to thereby blow at least a portion of said mixture towards the rear of the combine harvester. The preparation arrangement comprises a plate provided with fins mounted transversally with respect to the longitudinal direction of the harvester, each fin representing one of said preparation stages, the plate further comprising one or more openings between at least one pair of consecutive fins.
