A large number of ventilation pores 14 provided with 3 are opened (see FIG. 4).

[0005] Adjacent to either the left or right side plate (7b in the figure) of the sorting wire mesh 4, a remaining rice discharging wire mesh 16 which is inclined forward and low like the sorting wire mesh 4 is provided.
Is provided. As shown in FIG.
A large number of ventilation holes 29 are opened on a flat board surface. By making the vent hole 29 oval, it is possible to prevent the grain R from dropping and to increase the opening area. The guide plate 15 is erected on the other side of the remaining rice discharging wire netting 16,
Is integrally surrounded with the rear end of the sorting wire net 4. As shown in FIG. 4, a plurality of remaining rice outlets 11 are opened in the side plate 7 b of the sorting wire net 4 looking into the stone gathering portion 8, and the remaining rice outlet 11 is provided with a remaining rice discharging shutter 12 that opens and closes in conjunction therewith. , Respectively, to the remaining rice discharge wire netting 16. The windmill box 18 is provided with a wind tunnel section 20 having a windmill 19 at the lower front portion, a partition plate 17 extending in the front-rear direction from the wind tunnel section 20 to the wind guide path 21, and the wind of the windmill 19 is sorted by the wire mesh 4 and the remaining rice is discharged. It is configured to be divided and blown out to the wire net 16. Further, between the partition plate 17 and both side surfaces of the air guide passage 21, the ventilation holes 14 and the ventilation holes 29 are provided.
A plurality of rectifying plates 22 are attached so that the gust blast blows rearward on the sorting wire mesh 4 side and blows forward on the remaining rice discharging wire mesh 16 side.

The oscillating mechanism B has a pair of support plates 23 erected along the side surface of the machine frame 1, and between the support plates 23, a windmill rotation shaft 19 a of a windmill 19 and a crank rotation shaft 24 a of a swing crank 24. Are supported in parallel, and the electric motor 26, the windmill rotating shaft 19a and the crank rotating shaft 24a are respectively connected via pulleys.
Are connected by one belt, and the windmill 19 and the swing crank 24 are simultaneously rotated. One end of each of a pair of support rods 25 is rotatably supported at two front and rear positions on the upper portion of the support plate 23,
The other ends of these support rods 25 are rotatably attached to the side wall of the windmill box 18 of the sorting unit A. By the rotation of the swinging crank 24, the tip of the swinging crank 24 pushes up the wind tunnel portion 20 about the windmill rotating shaft 19 a, and the support rod 25 pivots about the support point of the support plate 23, and the separation wire 4 The rice discharge wire mesh 16 is swung in the front-back direction.

[0007] Here, the grain R mixed with the stone S is supplied from the tank 3 to the sorting wire net 4 through the grain feeding port 2, and the rocking of the sorting wire mesh 4 and the blowing wind blown out from the ventilation holes 14 cause the grain R to flow. , FIG.
As shown in FIG. 5, the stones S having a large specific gravity sink in the lower layer, and the grains R having a small specific gravity float on the upper layer of the sorting wire net 4. The upper grain R slides downward by its own weight along the inclination of the sorting wire net 4 by swinging and drops down by its own weight, and is discharged from the grain discharge port 6. The lower grain S is cut and raised and shaken by the tongue piece 13. Then, the stones gather at the stone gathering section 8 and periodically open the stone discharge shutter 10 to discharge the stones S from the stone discharge port 9 and discharge the stones to the outside by the stone discharge chute 27.

[0008] When the supply of the grains R from the tank 3 is completed, the operation is continued after that, the grains R remaining in the sorting wire net 4 are sorted, and the grains S are collected in the stone gathering section 8 and the stones are collected. It is discharged from the discharge port 9. With the stones S almost recovered,
The remaining rice discharge shutter 10 is opened, a plurality of remaining rice outlets 11 provided on the side plate 7b are simultaneously opened, and the grains R are sequentially transferred to the remaining rice discharge wire net 4 from the remaining rice outlet 11. Here, since the remaining rice outlet 11 is opened in a plurality along the slope of the remaining rice discharging wire mesh, the remaining grains R dispersed and sorted in the sorting wire mesh 4 are not shaken far to the vicinity of the stone gathering portion 8, and are nearby. Remaining rice outlet 11
Can be transferred to the remaining rice discharging wire net 16 in a relatively short time. Further, by flattening the remaining rice discharging wire mesh 16 and providing the ventilation holes 29 on the surface thereof, the transferred grains R are swung by the remaining rice discharging wire mesh 16 and the blast blowing out from the ventilation holes 29,
Send to the remaining US exit 28 promptly. When the amount of the grains R remaining on the sorting wire mesh 4 decreases, the blast generated by the windmill 19 flows more toward the sorting wire mesh 4 having less resistance to the ventilation of the grains R, so that the blowing quantity of the remaining rice discharging wire mesh 16 decreases. However, in this case, since the surface of the remaining rice discharging wire mesh 16 is smooth, the remaining rice discharging wire mesh 16 does not have the swinging action unlike the sorting wire mesh 4. Therefore, even if the blast is reduced, the remaining rice quickly slides down to the low remaining rice outlet 28 along the inclination of the sorting wire net 4 due to vibration.

[0009]

As described above, after the supply of the sorting object from the tank to the sorting wire net is completed, the remaining rice outlet is opened, the remaining rice of the sorting wire mesh is transferred to the remaining rice discharging wire mesh, and the remaining rice outlet at the lower end thereof. According to the first aspect of the present invention, since the remaining rice discharging wire mesh has a flat surface, even if the amount of air blowing up the remaining rice discharging wire mesh decreases, the remaining rice discharging wire mesh flows over the remaining rice discharging wire mesh. It slides down along the slope and can be quickly collected from the low remaining rice outlet 28. According to the second aspect of the present invention, since the plurality of remaining rice outlets 11 are arranged and opened along the inclination of the remaining rice discharging wire mesh, the grains R dispersed and remaining in the sorting wire mesh 4 are far away to the vicinity of the stone gathering section 8. It is possible to transfer the remaining rice discharging wire net 16 from the nearby remaining rice discharging opening 11 to the remaining rice discharging wire net 16 in a short time without swinging up. The residual rice discharge port 11 can be opened widely by slightly moving the residual rice discharge shutter, and the residual rice can be quickly transferred from the sorting wire net to the residual rice discharge wire net 16.
