PROBLEM TO BE SOLVED: To provide a combine which improves conveyance efficiency of grains between a first screw conveyor and a second screw conveyor, and reduces wear of a case part by means of suppressing a surface pressure due to an ejection blade causing grains to press on a case part.SOLUTION: A plate-like first ejection blade 147 is arranged continuously to a horizontal blade 143b at downstream end of a first conveyor 143. A plate-like second ejection blade 148 is arranged at a position facing the first ejection blade 147. The second ejection blade 148 is formed to be smaller than the first ejection blade 147 and is arranged such that a distance d1 from a case part 161 when the second ejection blade 148 is closest to the case part 161 is larger than a distance d2 between the first ejection blade 147 and the case part 161 when the first ejection blade 147 is closest to the case part 161. |
