Abstract

A harvesting machine comprising a transversely extending threshing 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 first and a second separating component, operable to submit the layer of crop material received from the threshing mechanism to a first and a second separating action. The first component comprises a separator cylinder cooperable with a separator concave and has a plurality of beater means transversely spaced apart on the width thereof. The beater means are arranged to impact on sections of the layer of crop material received from the threshing mechanism, thus submitting said material to said first separating action and conveying it to the second component. The second component comprises at least one separator rotor cooperable with a separator housing including a separator concave. The separator rotor carries at least one separator means which extends lengthwise of the rotor and which is arranged spirally to convey crop material received from the first separator component around the rotor to one of its ends while submitting it to said second separating …
