That is, the swinging sorting plate 4 is adjusted to an appropriate inclination angle according to the moisture content and dehulling rate of the grains to be sorted, and the sorting work can be carried out while increasing the sorting accuracy and efficiency.

Next, FIGS. 6 and 8 will be explained.

Reference numeral 48 denotes a flow velocity calibrator provided above the oscillating sorting plate 4. In this embodiment, the flow velocity detector 48 is composed of a rotary blade, and is arranged in the vertical direction of the oscillating sorting plate 4. It detects the flow velocity of grains. 49 is eccentric wheel 1
This is an oscillating rotary motor that rotationally drives 7.

The detection data of the flow rate detector 48 and the number of swings detector 50 of the swing sorting plate 4 are input to the calculation control unit 38 via the input interface 37, and are also input to the calculation control unit 38 from the calculation control unit 38 to the output interface 39. A drive command signal is outputted to the forward rotation rotation circuit 40 and the reverse rotation drive circuit 41 via the rotation speed adjusting means 5 for adjusting the rotation speed of the oscillating co-rotation motor 49.

When the detection data of the flow rate detector 48 and the number of swings detector 50 are input, they are compared and calculated with reference information in the arithmetic and control unit 38, and the flow rate of the flow rate detector 48 is determined by the arithmetic and control unit. If the number of oscillations is greater than the number of oscillations relative to the number of oscillations in the reference information in 38, a command signal is sent from the arithmetic control unit 38 to the forward rotation drive circuit 40 via the output interface 39 to slow down the rotation by a predetermined number of rotations. 51, the oscillating rotation speed of the oscillating sorting plate 4 is adjusted to decrease, and the flow speed of the flow speed detector 48 is outputted to the arithmetic control section 3.
If the number of oscillations is less than the number of oscillations relative to the reference number of oscillations in the reference information in 8, the arithmetic control unit 38 sends a command signal to the reverse rotation drive circuit 41 via the output interface 39 to increase the rotation speed by a predetermined number of rotations. Outputted to the adjustment means 51,
The number of oscillations of the oscillating sorting plate 4 is adjusted to increase, and the oscillating sorting plate 4 oscillates at an appropriate number of oscillations to maintain an appropriate sorting state.

Therefore, if the mixed rice has a high moisture content or is damaged and has a large coefficient of friction, the flow rate of the mixed rice toward the shaking side of the lower layer increases, and the flow rate of the mixed rice toward the shaking side of the upper layer increases. The flow speed becomes slower and the layer thickness on the shaking side becomes thicker, but in such a case, by reducing the number of swings, the mixed rice can be sorted while maintaining its proper distribution on the swing sorting plate 4. It is something that can be done.

In addition, instead of controlling the oscillating rotation speed of this oscillating sorting plate 4,
The vertical inclination angle of the oscillating sorting plate 4, the amount of supply to the oscillating sorting plate 4, the paulownia width of the oscillating sorting plate 4, the inclination angle of inclination #15.15 for reciprocating the oscillating sorting plate 4, It is also possible to adopt a configuration in which the brown rice partition plate 20 or the unhulled rice partition plate 21 is adjusted.
