In particular, the conveying system comprises a motion transmission assembly which ensures synchronism between the advancement of a first conveying device and the advancement of a second conveying device, so as to optimize the transfer of items carried by the first to the second conveying device and allow the items to be transferred in the smoothest possible way.

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 a retainer which may be engaged in a positive locking and/or friction-type connection with a continuous tension device of the grain elevator provided with one or more paddles so as to drive the continuous tension device. Several openings are provided in the drive wheel between the arms holding the retainer 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.
