  In a normal combine threshing device, the crops thrown into the handling chamber try to stay near the lower end of the receiving net due to its own weight, but the processed material is rotated by the rotating handling cylinder, thereby lowering the lower end of the receiving net. The crop is likely to stay in a region located on the lower side in the barrel rotation direction than the portion near the portion.

  In the above-described conventional configuration, the receiving net is provided in a state where the end on the lower side in the handling cylinder rotation direction and the end on the upper side in the handling cylinder rotation direction are positioned at the same or substantially the same height. The region from the vicinity of the lower end of the armor to the lower edge of the barrel rotation direction is shorter along the barrel rotation direction, and as a result, for example, the amount of crops to be introduced has increased. In such a case, in the region located on the lower side in the barrel rotation direction than the position near the lower end of the receiving net, there is a possibility that the threshing processing of a large amount of the processed material may not be sufficiently performed, and the threshing processing capacity is reduced.
