[Action]

 With this configuration, the processed products that have undergone threshing in the handling room and the processed products that have been discharged into the processing chamber from the dust outlet that opens in the culvert in the handling room and that have been subjected to the threshing action are on the rocking sorter. The No. 1 item is taken out of the machine from the No. 1 trough and the No. 2 item is collected by the No. 2 trough. The dust is re-sorted by the swing sorter, etc., and the dust is sucked from the suction ports on both the left and right sides of the suction dust fan and discharged from the discharge port to the rear toward the outside of the machine.

In that case, since the right suction port of the suction dust collecting fan faces the side portion of the receiving chamber of the processing chamber and is located at a short distance from the receiving network, the swing sorting body is removed from the receiving network. The dust discharged to the crocodile is immediately sucked out of the machine by the suction port on the right side, and the suction / dust suction fan displaces the processing chamber toward the crocodile. If the left suction port of the saw is made large, the suction force to the left suction port becomes strong, and the other side of the swinging sorter pulls the processed material from the processing chamber to the saw and the sort on the swinging sorter is pulled. In addition to making the layer thickness uniform, the dust on the other side of the rocking sorter floating in a wide range with respect to the suction / dust fan is sucked and discharged from the left suction port.
