る。EFFECTS OF THE INVENTION The known sorting plate uses wind because it guides scrap rice to the swaying side. When blown by the wind, light scrap rice emerges, but heavy brown rice does not emerge. The scrap rice that has surfaced can be made to drift to the swaying side with a gradient. In such a sorting plate, it is necessary to evenly distribute the scrap rice in the left-right direction, but the conventional one is not always sufficient because the sorting net itself has a slight wave, and the distribution is uneven. However, according to the present invention, the wind tunnel 2 having the wind turbine 3 provided in the fixed case 1 for blowing the wind upward, the swing frame 12 provided at the upper portion of the wind tunnel 2, and the swing frame 12 are stretched. It is composed of a sorting net 18 through which the wind blows upward, a supply device 31 for supplying scrap rice onto the sorting net 18, and a swinging mechanism for reciprocally swinging the sorting net 18 vertically and horizontally. The sorting net 18 has a substantially quadrangular shape with one side in the front-rear direction, the other side, the discharge side 20, the one side in the left-right direction on the upper side 21 and the other side on the lower side 22, and the supply side. 19 is higher than the discharge side 20 and the rocking side 21 is higher than the rocking side 22 and is inclined in both directions. On the surface of the sorting net 18, a plurality of elongated strips are arranged in the left-right direction at predetermined intervals in the front-rear direction. Debris on which a dam plate 34 such as a rail of a fitting, an L-shaped steel, or a strip steel is mounted and fixed Since in is obtained by a sorting device for taking out the rice from, the movement to the discharge side 20, weir plate 3 disposed at a predetermined distance on the upper surface of the sorting network 18
Since the flow is blocked by No. 4, it becomes slow and becomes a grain layer of several layers. Therefore, even if waves are formed on the sorting net 18 and it becomes uneven, it is widely dispersed without spots and has an effect of being well sorted. . Further, the present invention is a sorting device for taking out unpolished rice from the scrap rice in which a gap 35 is formed on the left and right sides of the dam plate 34 in the sorting device, and therefore, it is easy to clean.
