(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, it is diffused in the width direction and falls from the window 22, and at that time, the suction air path 21
The rice husks are air-sorted by the wind flowing through the rice husks, and the rice husks pass through the wind-selection section 12 and are sucked into the suction fan 16 and taken out to the outside.

Therefore, the shaft 17 of the suction fan 16 is connected to the eccentric wheel 1.
8 is attached, the diffuser 20 is swung by the eccentric wheel 18 via the rod 19, so that the falling object is well spread in the width direction, and after falling onto the diffuser plate 27, The liquid then falls into the distribution supply gutter 28 and flows toward one side 29 of the distribution supply gutter 28 .

The distribution supply gutter 28 is integrally constructed with the swing sorting device 23 and is swung in the grain flow direction by a known rocking device, so while being swung, the distribution and supply gutter 28 can be moved to one side as shown in FIG. During this time, the immature grains are sorted by the sorting hole 50, fall onto the flow plate 52 as shown in Fig. 4, move in the direction of 29 on one side, and are taken out from the unripe rice outlet 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 on the sorting plate 24, is placed on one side 2.
It flows in nine directions and reaches the switching valve 41.

In this case, the switching valve 41 operates the shaft 37 to leave all the drop ports 30 to 33 in the open state, so that while flowing through the distribution supply gutter 28, the partition plates 34 to
36 and is divided into four equal parts and supplied to the sorting plates 24 at each stage for sorting. However, when the work is about to end, the amount of mixed rice that falls into the distribution feed gutter 28 will be very small, so if this is still divided into four equal parts, the amount supplied to the sorting plates 24 of each stage will be insufficient. 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 fix it. distributed and well sorted.

(Effects) In the conventionally known Japanese Patent Application Laid-Open No. 59-49874, a sorting plate for shaking and sorting mixed rice is provided in a multi-tiered manner, and the upper part of the sorting plate is fixed to the side of the sorting plate. A device equipped with a distribution supply gutter that swings together with the sorting plate and distributes the mixed rice to the sorting plates of each stage, is described in which the grain lifting cylinder of the grain frying machine that supplies the rice to the distribution feed gutter is formed of a porous net. has been done. In addition, in the conventionally known Japanese Patent Application Laid-Open No. 59-70843, the upper part of the sorting plate for shaking and sorting mixed rice is fixed to the side of the sorting plate so that it swings together with the sorting plate and rotates in the direction of the shaking. A swinging sorting plate is described in which a feed gutter is provided which flows in transverse directions and distributes the mixed rice to the sorting plate, the bottom of the feed gutter being formed by a perforated plate having sorting holes.

However, in the former method of the above-mentioned known methods, immature rice is separated using a grain-lifting cylinder, but separation using a grain-lifting cylinder is technically difficult and sufficient effects cannot be expected. In the latter case, the grain flowing through the supply gutter is in a direction that intersects with the shaking direction, so even if impurities can be removed, small rice cannot be separated.

However, in the present invention, the sorting plate 24 for shaking and sorting the mixed rice is provided in a multi-tiered manner, and the sorting plate 24 is fixed to the upper part of the sorting plate 24 on the side of the sorting plate 24.
A distribution supply gutter 28 is provided which oscillates together with 4 and distributes the mixed rice to the sorting plates 24 of each stage by flowing in the oscillating direction. It is formed by a perforated plate 55 having a perforated plate 55, and is used as a distribution feed gutter in a hulling device in which the mixed rice from which small immature rice has been sorted is shaken and sorted by the sorting plate 24. A sorting plate 24 for dynamic sorting is provided in a plurality of stages, and the upper part of the sorting plate 24 is fixed to the sorting plate 24 side and swings together with the sorting plate 24 and flows in the swinging direction to sort each stage. Since the distribution supply gutter 28 for distributing the mixed rice is provided on the plate 24,
Since the distribution supply gutter 28 flows the grain in the swinging direction,
There is less grain dancing and distribution becomes smoother.

(b) Since the bottom surface of the distribution feed gutter 28 through which the grains flow in the oscillating direction is formed by a perforated plate 55 having sorting holes 50 that can separate the immature small rice, it is possible to sort the grains with less dancing.

This effect is achieved.
