ジ４３により勾配を微妙に調節して加減される。The scrap rice b on the sorting net 18 slightly floats when it receives wind, and the brown rice a does not float so much even when it receives wind because it is heavy. The slightly lifted scrap rice b does not come into contact with the wire net 23 that swings in the direction of the arrow W below that much, and therefore is not subjected to the swinging force of the sorting net 18, so the swinging side 22 side due to the gradient and the wind. To the discharge side 20 due to the gradient and wind. The flow to the swaying side 22 at this time is adjusted by finely adjusting the gradient by the adjusting screw 43.

To do. The movement to the discharge side 20 is delayed because the flow is blocked by the dam plate 34 arranged at a predetermined interval on the upper surface of the sorting net 18, and thus becomes a layer.
Disperses widely in the left and right directions. Further, since the weir plate 34 is welded to the upper surface of the wire net 23 of the sorting net 18 by the spot 34c, the wire net 23 that was undulating when unfolded.
Is corrected to be flat, so uneven distribution due to the unevenness of the wire net 23 is corrected. Further, as shown in FIG. 8, when the L-shaped steel 34d is brought into contact with the lower position of the punched perforated plate 25 and welded by the spot 34c, it becomes flatter.

ット３４ｃは各別に行なうので、製造容易である。EFFECTS OF THE INVENTION The above-mentioned known selection net utilizes wind for the purpose of guiding the 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 net, it is necessary to distribute the scrap rice evenly in the left and right directions.However, the conventional sorting net cannot be flat, and when it is spread, waves are created and stretched in an uneven state. In some cases, there were spots on the surface, resulting in poor sorting. 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 is
One side in the front-rear direction is a supply side 19, the other side is a discharge side 20, one side in the left-right direction is a swing side 21 and the other side is a swing side 22, and the supply side 19 is the discharge side 20. The rocking upper side 21 is higher than the rocking side 22 in both directions, and has a double structure in which a wire mesh 23 made of a woven mesh is adhered and polymerized on a punched perforated plate 25. Is mounted with a weir plate 34 such as rails 34a of a plurality of fittings elongated in the left-right direction at predetermined intervals in the front-rear direction, L-shaped steel 34b, or strip steel.
And the punched perforated plate 25 together with the wire net 23 made of the woven net as a sorting device for picking unpolished rice from the scrap rice that has been welded by the spot 34c. And because the weir plate 34 blocks the flow of waste rice into layers, it is evenly distributed on the left and right,
Select well. Further, in the present invention, in the sorting device, an L-shaped steel 34d is brought into contact with a position below the punched perforated plate 25 provided with the dam plate 34, and the dam plate 34 and the wire net 23 including the woven mesh and the Perforated Perforated Plate 25 and L-Shaped Steel 3
The wire net 23 becomes flatter because it is a sorting device for picking brown rice from the scrap rice that has been welded together with 4d by spot. Further, 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 on 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 upper side 21 is higher than the lower side 22 and is inclined in both directions, and has a double structure in which a wire mesh 23 made of a woven mesh is closely polymerized on a punched perforated plate 25, On the surface of the wire net 23, there are a plurality of joinery rails elongated in the left-right direction with a predetermined interval in the front-rear direction. A weir plate 34 such as 34a or an L-shaped steel 34b or a strip steel is placed, and an L-shaped steel 34d is brought into contact with a lower position of the punched perforated plate 25 provided with the weir plate 34, The dam plate 34 and the wire net 23
Are welded together by a spot 34c, and the punched perforated plate 25
And L-shaped steel 34d are welded together by a spot 34c,
Since the wire net 23 is superposed on the punched perforated plate 25 and the brown rice is taken out from the scrap rice welded by the spot 34c, the weir plate 34 and the wire net 23 are spots 34c and the punched porous plate. Since the spots 34c of the plate 25 and the L-shaped steel 34d are formed separately, the manufacturing is easy.
