A harvesting machine comprising a transversely extending threshold mechanism having a threshing cylinder cooperable with a threshing concave for threshing a layer of crop material fed therebetween and a separating mechanism having a separator rotor cooperable with a separator housing including a separator concave and disposed parallel to the threshing mechanism. Crop layer dividing means are foreseen on the separator rotor for dividing the layer of crop material received from the threshing mechanism into two portions. Separator means extend lengthwise of the separator rotor and are arranged spirally to convey said portions of the layer received from the threshing mechanism around said rotor in opposite directions to the opposite ends of the separating mechanism while submitting the crop material to a separating action.

A combine harvester comprising: a transversely extending threshing mechanism having a threshing cylinder cooperable with a threshing concave for threshing a layer of crop material fed therebetween; a separating mechanism having a separator rotor cooperable with a separator housing including a separator concave and disposed parallel to the threshing mechanism; crop layer dividing means on the separator rotor for dividing the layer of crop material received from the threshing mechanism into two portions and separator means extending lengthwise of the rotor and arranged spirally to convey said portions of the crop layer received from the threshing mechanism around said rotor in opposite directions to the opposite ends of the separating mechanism while submitting the crop material to a separating action; the crop layer dividing means being formed by crop layer divider blades disposed in pairs around the circumference of the separator rotor and at opposed angles relative to the direction of rotation in a manner defining V-shapes having their apexes facing in the direction of rotation; and the leading edges as seen in the direction of rotation of the rotor of each pair of crop layer divider blades are transversely spaced apart.
