In order to distribute the mixed rice falling from the spreading device 20 to the sorting plates 24 of each stage, distribution feeders 27 and 28 are provided below the spreading device 20.

The distribution supply gutter 27 is on the upper stage, and the distribution supply machine 28 is on the lower stage. The distribution and supply troughs 27 and 28 are both integrally attached to the swing type sorting device 23, and the six distribution and supply machines 27 that swing back and forth receive the mixed rice from the spreading device 20 and the distribution and supply machine 28. The zero-distribution feeder 28 that flows to the supply side is inclined, and on the negative side 29 there are drop ports 30, 31, which are divided into four equal parts in the width direction.
Form 32.33. Each of the drop ports 30 to 33 is
It is connected to each sorting plate 24, respectively. 34.35
．． 36 is a partition plate for forming the drop opening 30 to the partition plate 34, and the partition plates 34 to 36 have ends 38 and 39 on the circumference centered on the shaft 37 provided on the negative side. .40
Determine the length so that A switching valve 41 having a length that reaches the end portion 38 is attached to the shaft 37, and when the shaft 37 is rotated, the switching valve 41 is switched.

The distribution feeder 28 is formed by a perforated plate 55 provided with numerous sorting holes 50 for sorting immature rice. A receiving net 51 is provided below the perforated plate 55 with a gap therebetween, and a rubber pole 53 for preventing clogging is provided between the receiving net 51 and the perforated plate 55. Under the receiving net 51, flow plates 52 for unripe rice are placed at regular intervals.
An unripe rice outlet 54 is provided on one side 29 of the flow plate 52 so that the unripe rice can be taken out laterally from the unripe rice outlet 54. In addition, 42 is a finished rice flow gutter, 43 is a hopper, 44 is a finished rice elevator, 45 is a storage tank, 46 is an overflow tank, 47 is a paddy rice flow gutter, 48 is an end part, 4
9 is a return hopper.

Next, we will discuss the effect.

When the unhulled rice is put into the hopper 2, the unhulled rice elevator 1
The grain is fried and stored in the supply tank 3, and when the on-off valve 6 is opened by an appropriate amount, it flows into the hulling section 5 through the drop port 4, and is fed out little by little by the feeding roll 7, and the guide plate 10. Rubber piece 1
1, is supplied to a fixed hulling roll 8.9, is hulled, and flows into a spreading device 20. In the diffusion device w20, the rice husks are spread in the width direction and fall through the window 22, and at this time, the rice husks are sorted by the wind flowing through the suction air path 21, and the rice husks pass through the wind sorting section 12, are sucked by the suction fan 16, and are discharged to the outside.

Since the eccentric wheel 18 is attached to the shaft 17 of the suction fan 16, the spreading device 20 is swung by the eccentric wheel 18 via the rod 19, so that the falling objects can be spread well in the width direction. , after falling into the distribution supply gutter 27.
It falls from the distribution supply gutter 27 to the distribution supply gutter z8 and flows toward one side 29 of the distribution supply machine 28.

Since the distribution supply gutter 28 is integrally constructed with the swing sorting device 23 and is swung by a known oscillation device, the distribution and supply gutter 28 is swung downward toward one side 29 as shown in FIG. During this time, the immature grains are sorted by the sorting hole 50, fall onto the corrugated plate 52 as shown in FIG. 4, and move in the negative direction 29.
The immature rice is taken out from the unripe rice removal port 54. The mixed rice, which has been carefully selected so as to eliminate a considerable amount of immature rice and cause no hindrance to the next oscillating sorting of the sorting plate 24, flows in one direction 29 and reaches the switching valve 41.

In this case, the switching valve 41 operates the shaft 37.

Since all the drop ports 30 to 33 are left open, the partition plates 34 to 34 flow through the distribution supply gutter 28. It is divided into four equal parts by the partition plate 36, and is supplied to the sorting plate 24 at each stage for sorting. However, when the work is about to end, the amount of mixed rice that falls into the distribution feeder 28 will be very small, so if this is still divided into four equal parts, the amount supplied to the sorting plate 24 of each stage will be insufficient, and Therefore, in that case, operate the shaft 37 to rotate the switching valve 41, bring its tip into contact with one of the ends 38 to 40, and then
When fixed, the grain is distributed according to the amount and is well sorted.The conventionally known distribution feeder 28 merely distributes the grain. Therefore, mixed rice containing immature rice was supplied to the sorting board 24. However, when the amount of immature rice exceeds a certain level, it becomes a problem in the shaking sorting process, and conventional methods have not been effective in this regard.

However, in the present invention, the sorting plate 24 for shaking and sorting the mixed rice is provided in a multi-stage configuration, and a part of the sorting plate 24 is provided with a distribution supply gutter 28 for distributing the mixed rice to the sorting plate 24 at each stage. In the above, the distribution supply gutter 28 is formed by a perforated plate 55 having sorting holes 50 that can separate the unripe small rice, so that the unripe small rice can be sorted and then the mixed rice can be sorted by shaking. Since the distribution supply gutter in the sliding device is configured,
The sorting plate 24 is supplied with mixed rice that has been carefully selected to the extent that a certain amount of immature rice has been removed and does not interfere with rocking sorting.
It has the effect of improving the sorting effect.
