Feed beater directional vanes and scraper vanes

A combine harvester comprising:

• a transverse threshing drum which rotates on a transverse axis and which conveys crop material rearwardly in a generally longitudinal direction in an arcuate path from an inlet to an outlet;
• a feed beater arranged downstream of the threshing drum and which rotates on an axis parallel to said transverse axis of the threshing drum;
• a pair of axial separating rotors each extending side-by-side within respective housings in a longitudinal direction and serving to separate grain from straw, and,
• scraper apparatus;
• wherein the feed beater is located in front of the separating rotors to direct a crop flow rearwardly under the feed beater, the feed beater comprising directional vanes which direct the crop flow away from a central zone of the beater and toward respective crop streams associated with the two rotors, the scraper apparatus comprising stationary vanes provided above the beater, wherein crop material which back feeds over the top of the beater is scraped free of the beater and directed outwardly by the stationary vanes so that the scraped material is re-fed under the beater away from the central zone.
