(effect) Next, we will discuss the effect.

Paddy rice is stored in the paddy supply tank 1, the opening/closing shutter 3 is opened, and the paddy supply conveyor 4 is released from the discharge port 2.
When the unhulled rice is dropped, it is supplied to the loading port 7 by the rotation of the motor 5, ascends within the unhulled rice elevator 6, and is supplied to the unhulled paddy storage tank 9 through the discharge gutter 8. When the amount stored in the paddy storage tank 9 reaches a fixed amount, the rice husks are gradually supplied to the hulling section of the hulling machine 10 to be hulled, and the rice husks are sucked by the suction blower 12 from the chaff outlet 11 and discharged outside the machine. The immature rice is taken out from the immature grain outlet 13, and the mixed rice is supplied to the distribution device 16 from the mixed rice outlet 14, distributed to the sorting plates of each stage of the paddy shaking sorter 15, and shaken sorted.

The unhulled rice discharged from the unhulled rice take-out port 17 of the unhulled rice vibrating sorter 15 is returned to the return hopper 18 of the unhusked rice elevator 6, rises again inside the unhusked rice elevator 6, and is sent to the unhulled rice through the unhulled paddy storage tank 9 from the discharge gutter 8. The rice reaches the machine 10 and undergoes circular hulling.

Brown rice is taken out from the brown rice take-out port 19 of the paddy shaking sorter 15, and the brown rice is taken out from the loading port 22 of the brown rice elevator 21.
and flows into the switching valve 24 from the discharge gutter 23. The switching valve 24 is automatically switched by a color sensor 20 attached to the brown rice outlet 19, and when unhulled rice is mixed in the brown rice flowing out from the brown rice outlet 19, the color sensor 2 is switched.
0, the switching valve 24 is automatically switched to allow the flow to flow into the return tank 26.

A flow path switching valve 2 is also provided at the discharge part of the return tank 26.
7 is attached, and the flow path switching valve 27 is connected to the color selection sensor 38 provided in the return tank 26.
Switch by. That is, when the amount of unhulled rice is large, it is returned to the return hopper 18, and when the amount of unhulled rice is small, it is switched so that it is returned to the unhulled rice shaking sorter 15.

When the brown rice flowing out from the brown rice outlet 19 does not contain unhulled rice, the color sensor 20 switches the switching valve 24 in the direction of the grain sorter 25, and the brown rice flows from the switching valve 24 into the grain sorter 25 to be sorted. . The grain sorting machine 25 is a rice sorting machine, and a vertical line rice sorting machine, a rotary rice sorting machine, etc. are used. The waste rice taken out from the waste rice outlet 28 of the grain sorter 25 flows into the loading port 30 of the waste rice elevator 29 and is stored in the storage tank 37 via the discharge gutter 36. The grain rice taken out from the good rice take-out port 31 of the grain sorter 25 flows into the loading port 33 of the good rice elevator 32, moves up the good rice elevator 32, and is then stored in the storage tank 35 through the discharge gutter 34.

When the amount stored in the storage tank 35 reaches a fixed amount, the level switch 39 detects this and automatically stops the motor 5 or automatically closes the opening/closing shutter 3. level switch 40
The same is true.

(Effects) A paddy supply conveyor is installed at the bottom of the conventional paddy supply tank, and a paddy elevator is installed on the discharge side of the paddy supply conveyor.
The rice is supplied from the paddy lifter to the huller, and from the huller it is supplied to the swinging rice sorter for sorting.The grains are sorted at the good rice outlet, and brown rice is stored in a storage tank and scrap rice is stored in a storage tank. Such methods are known.

In the present invention, the mixed rice produced by hulling with the huller 10 is supplied to the rice shaking sorter 15 from the mixed rice outlet 14 to be sorted into unhulled rice and brown rice, and the sorter 15
The brown rice taken out from the brown rice outlet 19 is guided to the grain sorter 25 when only brown rice is present, and to the return tank 26 when unhulled rice is mixed, and the mixed rice in the return tank 26 is guided to the return tank 26. The color sorting sensor 38 provided in the sorting machine 26 detects the amount of unhulled rice, and when the amount of unhulled rice is small, the distributing device 16 of the sorting machine 15
Automatic switching method in a hulling/hulling device in which the unhulled rice is guided to the hulling machine 10 for processing when there is a large amount of unhulled rice, and the hulling machine 10, and the mixed rice that has been hulled by the huller 10 is supplied from the mixed rice outlet 14 of the huller 10 to the paddy shaking sorter 15 for sorting. The brown rice outlet 19 of the dynamic sorter 15 is connected to the brown rice elevator 21, and the discharge gutter 23 of the elevator 21 is equipped with a switching valve 2.
The grain sorter 25 and the return tank 26 are connected through the
is provided, and the paddy shaking sorter 15 is connected via the valve 27.
and the huller 10, and the valve 27 is an automatic switching device in the huller and grain sorting device, which is switched by the color sorting sensor 38 provided in the tank 26, so that it is possible to shake and sort the rice. When unhulled rice is mixed in the brown rice taken out from the brown rice outlet 19 of the machine 15, the switching valve 24 is automatically switched to allow it to flow into the return tank 26.
When the amount of unhulled rice is large, the flow path switching valve 27 of the discharge section of No.
8, and when the amount of unhulled rice is small, it is returned to the paddy oscillating sorter 15, so that the effect of automatically performing cyclic sorting and cyclic hulling is achieved.
