Abstract

A drive unit for a grain elevator, in particular for agricultural machines, has a drive wheel operatively connected to a screw conveyor for conveying crop into the grain elevator. The drive wheel is provided with retainer means which may be engaged in a positive locking and/or friction-type connection with a continuous tension means of the grain elevator provided with one or more paddles so as to drive the continuous tension means. Several openings are provided in the drive wheel between the arms holding the retainer means in such a way that this allows or facilitates crop conveyed by the screw conveyor into the grain elevator along a direction of conveyance to flow through the drive wheel.
