Abstract:
In a crop residue chopping and distributing arrangement for a combine harvester (10) with a straw chopper (60) and two discharge blowers (100), a guide element (150) distributes the crop residue stream over the two discharge blowers (100) is arranged between said blowers. Passages (162) remain between the guide element (150) and the discharge blowers (100) such that the crop residues can be rearwardly discharged onto the field by the straw chopper (60) through said passages. Outer guide elements (141) are provided between the straw chopper (60) and the discharge blowers (100) in order to deflect the outer regions of the crop residue stream inward. The straw chopper housing (19) may feature a curved bottom (112) that axially conveys the crop residues to the discharge blowers (100) at an angle, wherein a flat crop residue guide element (112) is arranged between the straw chopper housing (90) and the discharge blowers (100).
