(effect) Next, we will discuss the effect.

When unhulled rice is put into the hopper 2, it is lifted by the unhulled rice elevator 1 and stored in the supply tank 3. When the on-off valve 6 is opened by an appropriate amount, it flows into the hulling section 5 through the drop opening 4 and is recycled. The grains are fed out little by little by the loading roll 7, flow over the guide plate 10 and the rubber piece 11, are supplied to the fixed hulling rolls 8 and 9, are hulled, and flow into the spreading device 20. In the diffusion device 20, the rice husks are spread in the width direction and fall onto the window 22, and at this time, the rice husks are screened by the wind flowing through the suction air path 21, and the rice husks pass through the wind selection section 12, are sucked into the suction fan 16, and are discharged to the outside.

Therefore, the shaft 17 of the suction fan 16 is connected to the eccentric wheel 1.

It falls from the gutter 27 into the distribution supply gutter 28 and flows toward the terminal end 29 of the distribution supply gutter 28 .

Then, due to the action of the guide plate 41, a large number of divided channels 3 are formed.
Among 0, 31, 32, 33..., grains flow into only the divided flow path 30 (or only the divided flow path 30 and the divided flow path 31), but the divided flow path 30 has a blocking plate 37 that blocks this. Since the blocking plate 37 is provided with the constriction passing portion 38, the divided flow path 30
(or the divided flow path 30 and the divided flow path 31) become full depending on the flow rate, and flow over the partition plate 34 and flow into the divided flow path 32, and thereafter similarly overcome the partition plate 36 and flow into the divided flow path 33. do.

Therefore, the sorting plate 24 at each stage is supplied with only the material that has passed through the constriction passage section 38, so that a fixed amount is always supplied.

(Effects) As mentioned above, conventionally, the sorting plates for shaking and sorting the mixed rice are arranged in multiple stages and the upper part of the sorting plates is provided with a distribution supply gutter for distributing the mixed rice to the sorting plates at each stage. In this method, the grain was divided into several parts in the width direction while flowing toward one side.
The most important point in effectively performing the oscillating sorting is to keep the amount of grain supplied to the sorting plate constant.
However, in the past, emphasis was placed only on equal distribution, and little consideration was given to the fixed amount.

However, in the present invention, a sorting plate 24 for shaking and sorting the mixed rice is provided in a multi-stage configuration, and a distribution supply gutter 28 is provided on the upper part of the sorting plate 24 for distributing the mixed rice to the sorting plate 24 at each stage. In this case, the terminal end 29 of the distribution supply gutter 28 is separated by a partition plate 34 perpendicular to the width direction.
Divide into equal parts by 35, 36... and separate the sorting board 24 at each stage.
The divided channels 30, 31, 32, etc. are formed, and any part of the divided channels 3 is formed in the front distribution supply gutter 28.
A guide plate 41 for guiding grains is provided only in the channel 0, and a constricted passage section 38 smaller than the channel is formed in the middle of the divided channel 30, 31, 32 so as to overflow. This is a distribution supply gutter in a hulling device in which the water passes over the tops of the vertical partition plates 34, 35, 36, and sequentially flows into the adjacent divided channels.
Due to the action of the guide plate 41, a large number of divided channels 30, 31,
Among 32, 33..., grains flow into only the divided flow path 30 (or only the divided flow path 30 and the divided flow path 31), but the divided flow path 30 is provided with a blocking plate 37 that blocks this. The plate 37 has a constriction passing portion 38.
is provided, the divided flow path 30 (or the divided flow path 30 and the divided flow path 31) becomes full according to the flow rate, and the flow passes over the partition plate 34 and flows into the divided flow path 32. It passes over the plate 36 and flows into the divided flow path 33 .

Therefore, since only the material that has passed through the constriction passage portion 38 is supplied to the sorting plate 24 at each stage, the effect is achieved that a fixed amount is always supplied.
