Abstract
An inclined conveyor for a combine harvester has two drive elements which define a conveying direction and revolve in a conveying duct. Conveying duct is divided into an overshot return duct and an undershot conveying duct by a separating element situated between the upper run and the lower run of the drive element. Drive element is interconnected by carriers situated transversely with respect to conveying direction that convey harvested crop in undershot conveying duct. The difference in speed between the carrier bars and harvested crop stream is eliminated, and at least reduced, by additional acceleration of harvested crop stream. Carrier bars serve as carriers, and as acceleration elements for the harvested crop. That is because the cross section of each of the carrier bars viewed in conveying direction, occupies at least 30% of the smallest internal cross section of undershot conveying duct.
