Abstract
A threshing and separating apparatus particularly for use in a combine harvester includes a threshing rotor having a generally conical outer surface cooperating with a generally conical inner surface of a stator so that crop material fed to the narrower end of the rotor moves between the surfaces to provide a threshing action. At the discharge end of the annular channel between the rotor and stator is provided a separating sleeve which is rotated around the rotor separately from the rotor and stator. The sleeve is perforated to allow radial escape of seeds under a centrifugal force and a fan generates an air flow entering the sleeve from the feed end and pulled out of the sleeve from the discharge end so that lighter materials such as chaff are drawn through the space of the discharge end while the seeds escape outwardly.
