PROBLEM TO BE SOLVED: To provide a post-processing device of a combine harvester that can more uniformly separate cut waste straws to right and left when the cut waste straws cut by a cutting unit and falling are separated by a horizonal diffusing spiral to right and left.SOLUTION: A post-processing device of a combine harvester includes a cutting unit 24 for cutting grain culm thrashed and made into waste straws. A horizontal diffusing spiral 26 for diffusing the cut straws cut by the cutting unit 24 is disposed below the cutting unit 24. A guide member 27 for receiving and guiding the cut straws falling from the cutting unit 24 so that the straws remain on the diffusing spiral 26 side is disposed below the diffusing spiral 26 with a space S secured between them. The guide member 27 is so formed that in the space S between the diffusing spiral 26 and the guide member 27, the guided side of the cut straw on the tip side is narrower than the guided side of the cut straw on the root side. |
