【The invention's effect】
Since it comprised as mentioned above, this invention has the following effects.
Since the swinging body of the swing sorting device is made of synthetic resin, the swinging body is made of synthetic resin to reduce the weight, simplify the structure, make manufacturing easier, and reduce costs. In addition, since the left and right side plates at the approximate center in the front-rear direction of the swinging body located below the rear part of the handling cylinder are connected by a connecting body, there is an adverse effect on the selection at a position where the leakage amount of the threshed straw is small. Without giving, the rigidity of the central part of the swinging body could be increased.
Further, since the swing support shaft arranged at the front of the swing body made of synthetic resin is horizontally mounted on the side plate portion of the swing body 51, the lower portion of the swing body can be reinforced, and the swing support shaft Does not protrude inside the side plate, does not interfere with sorting, and does not interfere with other parts.
