Therefore, in the present invention, in order to achieve the object described in the preceding paragraph, in the threshing machine described at the beginning, the opposite side of the sorting dust chamber from the feed chain is widened. At the same time, the rear side of the swinging / sorting body installed in the sorting / dusting chamber from the culm side of the handling chamber is bulged into the widening of the sorting / dusting chamber, and the sorted material on the swinging / sorting body is bulged to the expanded portion. It was constructed by sloping the leveling plate that was transferred to the saw. Moreover, it is preferable that the bulging portion of the rocking sorting body extends below the processing chamber.

[0005]

With this configuration, the threshing materials threshed in the handling room are dropped on the rocking sorting body and sorted by being sent backward by the rocking movement, and processed from the dust outlet on the culm side of the handling room. What is delivered to the chamber is processed in this processing chamber, and the processed product falls into the bulging portion of the rocking sorting body and is sorted. At this time, the leveling plate transfers the sorted materials to the wales at the bulging portion and disperses them to evenly distribute the layer thickness and effectively utilize the sorting surface for accurate sorting. The processed products from swelling can be efficiently sorted by the expanded sorting surface of the swing sorting body, and the sorted first product is taken out by the fried cylinder, and the second product is shaken by the reducing cylinder. It is returned to the dynamic sorter.
