Abstract
A crop residue distributor assembly for a combine harvester. The crop residue distributor includes a straw distributor hood, below which a number of adjustable vanes is arranged on both sides of a longitudinal median plane of the crop residue distributor assembly. A flow divider is arranged adjacent to the longitudinal media plane with diverging walls. The flow divider is coupled to the vanes in such a way that the flow divider moves together with the vanes when the vanes are adjusted.

A crop residue distributor assembly for a combine harvester comprising:
- a straw distributor hood, below which a number of adjustable vanes is arranged on both sides of a longitudinal medial plane of the crop residue distributor assembly, and
- a flow divider with diverging walls rigidly connected to each other and adjacent to the longitudinal medial plane, wherein the flow divider is coupled with the vanes in such a way that the flow divider moves together with the vanes when the vanes are adjusted.
A combine harvester comprising:
- a straw chopper;
- and
- a crop residue distributor assembly mounted downstream of the straw chopper, wherein the straw chopper includes a straw distributor hood, below which a number of adjustable vanes is arranged on both sides of a longitudinal medial plane of the crop residue distributor assembly, and a flow divider with diverging walls rigidly connected to each other and adjacent to the longitudinal medial plane, wherein the flow divider is coupled with the vanes in such a way that the flow divider moves together with the vanes when the vanes are adjusted.
A method of distributing crop residues of a combine harvester with a crop residue distributor, the method comprising:
- delivering the crop residues to the crop residue distributor;
- adjusting a position of distributor vanes with respect to a distribution hood;
- and
- moving a flow divider, having diverging walls rigidly connected to each other, together with the adjusting the position of the distributor vanes in order to deflect the crop residues in a desired direction and to achieve an even distribution of the crop residues on a field.
