Abstract
A self-propelled combine harvester has an axial-flow separating device including a chopping device with supporting rings which carry impact teeth. The main body of each separating rotor is equipped with several positioning profiles, which are rigidly connected to the main body and extend spirally around it. The supporting rings are provided with corresponding grooves. As a result, a form-locking connection is made between the supporting rings and the main body. The positioning profiles are toothed at the longitudinal edge leading in the direction of rotation of the separating rotor, so that the regions of the supporting rings adjoining the recesses engage in the tooth gaps are prevented from sliding axially. A locking ring is releasably mounted on the rear end of the main body. The number of parts is minimized and the construction of the supporting rings carrying the impact teeth and the main body of the separating rotor minimize the assembly time.
