摘要：
The present invention is related to a combine harvester comprising a driving shoe arrangement. The driving shoe includes a preparation pan and one or more sieves, coupled to a drive mechanism for driving a reciprocating movement of the pan and sieves. The stroke of the reciprocating movement of the pan and/or sieves is adjustable in a combine according to the invention, through the application of a drive mechanism including one or more pivotably mounted support arms for supporting the pan or sieve, and a drive arm connected to one of said support arms through an adjustable connection means. According to a preferred embodiment, the adjustable connection means comprises a variable length actuator whose length determines the stroke of the pan or sieve. The stroke of said pan or sieve can be adjusted during a harvesting run of the combine harvester, thereby allowing a fast adjustment to changing external conditions such as the slope of the terrain. Adjustment of the stroke can be done manually and/or automatically through sensors and control means.
