The mixed rice supplied to the rocking sorting plates 21, 21, ... Is unbalanced due to the grain size, the specific gravity, the friction coefficient, and the like.
Paddy rice, which has a larger and lighter specific gravity than brown rice, drifts to the swaying side 25, and unmixed paddy rice and brown rice that do not separate flow to the middle part, which is the discharge side of the rocking sorting plates 21, 21 ,. Two
Grains flowing down from 3 are brown rice partition plate 39 and paddy partition plate 4.
Partitioned by 0, brown rice is taken out from the brown rice outlet 41, mixed rice from the mixed rice outlet 42, and paddy rice from the paddy rice outlet 43, respectively.

The brown rice thus taken out is taken out of the machine through the brown rice passage 38 and the brown rice frying machine 20, and the paddy rice passes through the paddy rice passage 45 and the paddy grain section of the fried grain conveying section 5 to hull. It is returned to part 1 and hulled again.
The mixed rice flows down through the mixed rice passage 46 to the mixed rice fried portion of the fried food conveying section 5, and the swinging selection plates 21 and 2 are again in the mixed rice fried portion.
The configuration is such that it is supplied to 1, ...

In this way, the paddy-feeding control valve 11 is selected by hulling and sorting, but when the grains in the mixed rice hopper 29 decrease and move upward, the interlocking members 14, 14 made of wires or the like cause the paddy-feeding control valve 11 to move. And the bottom plate portion 9b of the diffuser 9c is adjusted in relation to the opening side, the amount of hulling in the hulling portion 1 is increased and adjusted, and conversely, the grains of the mixed rice hopper 29 are increased and the mixed rice hopper 29 is lowered. When moved, the interlocking members 14 and 14 adjust the paddy supply control valve 11 and the bottom plate portion 9b of the diffuser 9c to the closed side, and the paddy amount in the paddy portion 1 is adjusted to be reduced. As described above, when the sliding amount of the hulling rolls 7 and 7 increases, the opening of the bottom plate portion 9b of the diffuser 9c is adjusted so that the slidable rice is slid from the entire width of the hulling rolls 7 and 7 to the slidable rice wind selection path 15. It is possible to diffuse and fall into the whole area, equalize the amount of fall in the entire width of the scraped rice wind selection path 15, and improve the wind selection accuracy. In addition, in the conventional device in which the bottom plate 9b is not opened and closed, when the amount of slid rice is increased, the amount of drop from both left and right sides of the diffuser 9c is increased, and the amount of drop in the entire width of the slid rice wind selection path 15 is even. Although it has a drawback that it is not realized, such a drawback can be solved.

During the hulling / sorting operation, the mixed rice hopper 2 is used.
The grain supply state of No. 9 is observed by the grain sensor 33, and it is judged up to how many sheets of the swing sorting plates 21, 21, ... If it is appropriate to perform the sorting with 21, ..., The adjustment plate 34 is moved and adjusted to open the distribution passages 32, 32, ... corresponding to only the three swing sorting plates 21, 21 ,. And then supply the grain,
The other distribution passages 32, 32, ... Are closed so as not to supply the grains to the other swing selection plates 21, 21 ,.
Since the sorting can be performed, it is possible to prevent the grain having less than the sorting ability from being supplied to the unit swing sorting plate 21, and to eliminate the swing sorting plate 21 having poor sorting, thereby improving the sorting accuracy. Can be planned. In this embodiment, the adjusting plate 3
4 is manually adjusted, but the adjustment plate 34 may be automatically adjusted according to the detection result of the grain sensor 33.

Next, FIG. 5 will be described. 47 is
The paddy storage tank is provided with an opening / closing valve 48 and an opening / closing adjustment motor 49 at the lower outlet of the paddy storage tank 47, and is supplied to the paddy hopper 6 of the paddy sorting machine via the communication passage 50. Although the structure of the hulling / sorting machine is not shown in the drawings, it is well known that the gap between the hulling rolls 7 and 7 can be adjusted and controlled by the removal rate of the slid rice or the load current value of the hulling rolls 7 and 7. It is a type. In the subsequent process of the brown rice lifting machine 20 of the hulling and sorting machine, a known grain sorting device 51 for sorting small rice from brown rice.
, And the refined brown rice sorted by the grain sorting device 51 is supplied to the brown rice storage tank 53 via the brown rice lifting machine 52. At the lower end of the paddy storage tank 47, a grain sensor 54 capable of detecting that the amount of paddy remains low.
When the grain sensor 54 detects that the amount of paddy in the paddy storage tank 47 has become less than or equal to a predetermined amount, the signal is sent to the control box (not shown) of the paddy hull sorting machine. The configuration is such that the gap adjustment between the hulling rolls 7 and 7 from the control box is stopped, and the hulling work is performed with the gap between the hulling rolls 7 and 7 being fixed. Therefore, a large number of straw debris and the like are often mixed in the grain finally supplied from the paddy storage tank 47 to the paddy sorting machine, and when the removal rate control or the load current control is performed, the paddy is removed. Although there is a drawback that the hulling work is not stable because the rolls 7 and 7 are frequently adjusted to be wide or narrow, this drawback can be solved.

Further, the control box is constructed so that data such as the farmer name of the grain during the hulling operation, the paddy variety, the water content, etc. are artificially input and stored. When the work is resumed, if the grain name of the grain stored in the brown rice storage tank 53, the paddy variety, the water content, etc. are the same, the operation is resumed immediately, but if some or all of them are different,
An abnormal alarm device (not shown) is activated, and a valve (not shown) at the inlet of the brown rice storage tank 53 is configured so as not to open, and the brown rice fried machine 52 lifts it to another brown rice storage tank (not shown). After switching to be grained, the hulling and sorting work is started.
