Operation of the Embodiment Next, the operation will be described. In general, brown rice that has been hulled by a hulling device has 10 to 20% of the waste rice removed by a rotary scrap rice sorting device, and is marketed as finished rice. However, since the removed scrap rice contains about 20% or more of brown rice, conversely, a device for extracting the brown rice from the scrap rice is required. Although the present invention is capable of general grain sorting, it is effective when sorting brown rice from scrap rice. Therefore, as an example thereof, the opening / closing valve of the non-lightweight grain hopper 44 below the non-lightweight grain extraction port 28 will be described. 48 and lightweight grain outlet 30
Keep the open / close valve 49 of the light weight grain hopper 46 at the bottom of both of them closed, and move the knob 26a to the left and the knob 27a to the right so that the non-lightweight grain hopper 44 and the light weight grain hopper 46 are maximized and the non-lightweight grain hopper is increased. Hopper 4
4 a non-lightweight grain container 50 at the bottom of the lightweight grain hopper 46
When the light weight grain containers 51 are arranged in the lower part of each, the switch 15 is turned on and the motor 15 is energized, the pulley 7 and the pulley 11 are rotated via the belt 17, the wind turbine shaft 6 and the drive shaft 8 are rotated, and the wind turbine shaft 6 is rotated. The fixed wind turbine 3 is rotated to blow air from the outlet 5, and the swing frame 12 is swung by the eccentric wheel 9 and the rod 10 provided on the drive shaft 8.
The swing frame 12 is fixed to the fixed frame 1 by the tilt swing support rods 14, 14.
Since it is attached to, it will tilt and swing in the W direction when swinging.

In this state, when the mixed grain of the non-lightweight grain (brown rice) a and the light grain (blown rice) b is supplied to the sprue 36,
The grain is fried by the feeding device 31 and flows down on the scrap rice sorting net 37 in the supply trough 32, and at this time, the waste rice c of extremely small grain having no utility value is separated by the scrap rice sorting net 37 and the lower net 38 is also separated. As is the case, the mixture of non-lightweight grain a and light weight grain b, which has flowed on the waste rice flow plate 39 below and taken out to the extraction trough 42, flows down on the waste rice sorting net 37 and is selected from the supply port 33. It is supplied to the rocking side 22 of the net or plate 18.

However, at the initial stage of supply, the light-weight grain b is not sorted out and the light-weight grain b is discharged to the non-lightweight grain extraction port 28 and the non-lightweight grain a is mixed to the light-weight grain extraction port 30.
Since both are closed, they are not discharged, and a fixed amount is stored without being sorted. However, since the non-lightweight grain hopper 44 and the lightweight grain hopper 46 are made to be the largest size, they are generally sorted well by the time when they are stored in them, but the partition bodies 26 and 27 are merely umbrella-shaped. In this shape, the highest upper end is formed to be lower in height than the sorting net or the plate 18, so that the grain overflowing the non-lightweight grain extraction port 28 and the light weight grain extraction port 30 is the intermediate rice in the adjacent portion. It automatically flows into the outlet 29 and is returned to the supply device 31 through the trough 47. After a while, the sorting on the sorting net or the plate 18 becomes good, and at that time, when a small separate container is applied to the lower part of the opening / closing valve 48 to open the opening / closing valve 48, the non-lightweight grain hopper 44 is opened. Since a certain amount of poorly sorted rice that has accumulated in it is taken out into a container, it can be returned to the supply device 31 through the trough 47 if it is in the intermediate rice taking hopper 45.
In the same manner, by opening the opening / closing valve 49, a certain amount of unsorted rice accumulated in the light weight grain hopper 46 can be taken out, and this is opened in the intermediate rice taking hopper 45 and returned to the feeding device 31. After that, since the on-off valves 48 and 49 are still open, the non-lightweight grain container 50 installed at the lower position
And the waste rice container 51 is taken out, respectively.
