Combine harvester with top-located cleaning arrangement

摘要

In a combine harvester the cleaning arrangement is placed above the threshing and separation system so that the sieves of the cleaning arrangement can be wider than the distance between the front wheels or tracks of the harvester. A supply such as one or more auger beds are provided underneath the threshing and separation system, for gathering the grain/residue mixture in a single location. From that location, an elevator transports the grain/residue mixture up towards the cleaning arrangement, where it is distributed over the width of the cleaning arrangement.
