The feed-back cylinder which rotates in the direction and flips up the one reaching the terminal end of the sorting body to the upper rear side, and a return path leading to the second trough between the feeding cylinder and the swinging sorting body terminal end. Since a dust drop path is formed between the feeding cylinder and the rear wall of the dust chamber, fine dust of the dust is sucked into the suction dust fan. The grains that have been ejected to the outside of the machine and reached the end of the rocking sorter in a state where they are contained in the dust are diffused by the rewinding cylinder that rotates counterclockwise and are splashed backward and upward. The waste is separated from the waste and falls into the return channel and is collected in the second trough. In addition, large pieces such as broken stems and husks in the waste are diffused by the feeding cylinder. By the action and the suction wind of the suction dust exhaust fan, it is sent to the dust fall path side and discharged to the outside of the machine, so that the shell grains and dust particles are reliably separated and the grain particles are mixed in the dust particles. It does not scatter to the outside of the machine, and the large dust particles are sent to the dust drop path side and discharged outside the machine as described above, so the sorting condition of the 2nd product is good. It has a versatility in that it is compatible with various grain removals such as soybeans and buckwheat as well as rice and wheat. Than it is seen the implementation of the sorting device.

Further, as described in claim 2 of the utility model registration, a switch guide plate that can be opened and closed is provided in the dust drop path, and the one that is sent to the dust drop path side by the feed cylinder is located below the feed cylinder. By constructing so that it can be returned to the second gutter through the reducing path, it becomes possible to cover the processing state when the shedding action is insufficient, and good results are obtained.
