The window 32 is formed so that objects falling from the window 30 fall through the window 32.

33 is a swing type sorting device, which has several stages of sorting plates 3.
The planar shape is as shown in Fig. 5, and it is horizontally swingable in the front-rear direction, and is approximately square in shape with a front wall 35, a rear wall 36, a right wall 37, and a left wall 38. The front side of the left wall 38 is cut out to form a brown rice outlet 39, the rear side of the right wall 37 is cut out to form a paddy rice outlet 40, and the rear wall 36 of the sorting plate 34 is cut out to form a brown rice outlet 40. A paddy rice protrusion 41 is formed on the entire surface of the rice protrusion 41, which is inclined in the direction of the unhulled rice outlet 40, and the outer part thereof, that is, the part closer to the front wall 35 of the sorting plate 34, is inclined in the direction of the brown rice outlet 39. Brown rice protrusions 42 are formed on the entire surface.

A brown rice flow gutter 43 that flows from the front side to the rear side is provided on the outside of the brown rice outlet 39.

The brown rice flow gutter 43 is for separating immature rice from the brown rice supplied from the brown rice outlet 39.

The brown rice flow gutter 43 has a rectangular gutter shape as shown in FIG. 2, and is composed of a bottom plate 44, a middle screen 45, and an upper screen for removing immature rice 46, which are stacked in three stages from the bottom to form an inner wall. 61 and an outer wall 62.

The inner wall 61 is attached to the lower inner side of the sorting plate 34, so that the width of the immature rice removal net 46 can be formed to the desired width without increasing the width of the machine body. The brown rice supplied from the brown rice outlet 39 to the immature rice removing net 46 is completely separated into a thin layer.

The outer wall 62 is formed outside the brown rice outlet 39 so as to surround it.

From the above, it can be said that the bottom plate 44, the middle net 45, and the immature rice removal net 46 are formed so as to penetrate inside the side edges of the sorting plate 34.

The bottom plate 44 is low on the rear side and high on the front side, and countless protrusions 47 are formed on the bottom plate 4 to move immature grains to the high front side.
It is formed on the plate surface of 4. 48 serves as an outlet for immature grains. The middle net 45 is a rubber ball holder and is provided in parallel with the bottom plate 44, and is formed of a woven net, and the upper part of the middle net 45 is provided with partition plates 49 at regular intervals.
is provided, and an immature rice removal net 46 is provided on the partition plate 49. The immature rice removing net 46 is formed with sorting holes 50 for sorting immature rice.

In addition, in the figure, 51 is an elevator for finishing rice, 52 is a brown rice return hopper, 53 is a storage tank, 55 is an on-off valve, 56 is a spring, 57 is a paddy rice return gutter, 58 is a paddy rice return unit, 59 is a rocking device, 60 is a distribution supply gutter.

(effect) Next, we will discuss the effect.

When unhulled rice is put into the hopper 3, it is fried by the bucket conveyor 2 and flows into the storage tank 5 through the discharge port 4. When the on-off valve 9 is opened by an appropriate amount, it flows into the inflow cylinder 8 from the drop port 6, is fed out little by little by the control valve 12 and the feed roll 10, flows over the guide plate 13 and the rubber piece 16, and then flows over the hulling roll 14. ，
The rice is supplied to the supply section 17 of No. 15, is hulled, and flows into the diffusion device 30 from the discharge section 18.

In the diffusing device 30, the rice husks are spread in the width direction and dropped through the window 32. At this time, the rice husks are sorted by the wind flowing through the suction air path 31, and the rice husks pass through the wind barrel 22, are sucked into the suction fan 24, and are discharged to the outside. At this time, since an eccentric wheel 27 is attached to the shaft 26 of the windmill 25 of the suction fan 24, the diffuser 30 is swung by the eccentric wheel 27 via the rod 28, so that the falling objects can be dispersed well. , is distributed by the distribution supply gutter 60 and flows into the sorting plate 34. Sorting board 3
4 is horizontally reciprocated in the direction of arrow A by a rocking device 59, so that the grain rotates in the center thereof, and the unhulled rice transfer protrusion 41 and the brown rice transfer protrusion 4
Due to the action of 2, the brown rice is transferred from the brown rice outlet 39 to the brown rice flow gutter 4.
3, and the unhulled rice is taken out from the unhulled rice take-out port 40 to the unhulled rice return gutter 57.

The brown rice taken out to the brown rice flow gutter 43 flows over the immature rice removal net 46 and flows into the brown rice return hopper 52, but in this case, the inner wall 61 of the brown rice flow gutter 43 enters the lower inside of the sorting plate 34. Because of this, although the width of the machine is not increased, the width of the unripe rice removal net 46 is made as wide as possible, so that unripe rice can be removed from the brown rice removal port 39. The brown rice supplied to the rice removal net 46 is turned into a thin layer and subjected to shaking, and since the shaking is horizontal shaking, the grains do not jump and are completely sorted.

The completely unpolished rice that has risen through the finished rice elevator 51 is stored in a storage tank 53, but at this time, immature grains are sieved through a sorting hole 50, passed through an inner screen 45, and stored on a bottom plate 44. Since the bottom plate 44 is integrally constructed with the swing type sorting device 33 and reciprocates horizontally, the bottom plate 44 can be taken out to the outlet 48 by the action of the protrusion 47.

Since the brown rice stored in the storage tank 53 does not contain immature grains, it is immediately packed into bags. The unhulled rice taken out to the unhulled rice return gutter 57 is returned to the elevator 1 through the unhulled rice return section 58 and is reprocessed.

(Effects) In the known method, since the sorting plate swings in the horizontal and horizontal directions, the immature rice removal net also swings in the horizontal and horizontal directions, causing the immature rice to move around and result in poor sorting.

However, the present invention provides a sorting plate 34 that swings in the front and back horizontal directions, a brown rice outlet 39 formed at one left and right end of the sorting plate 34, and an unhulled rice outlet 39 formed at the other left and right sides of the sorting plate 34. 40, a brown rice protrusion 42 inclined in the direction of the brown rice outlet 39 formed on the front half of the plate surface of the sorting plate 34, and the unhulled rice outlet 42 formed on the rear half of the plate surface of the sorting plate 34. and a protrusion 41 tilting in the direction of the sorting plate 34.
has a plurality of stages, and a brown rice flow gutter 43 is provided in the front and back direction outside the brown rice outlet 39 at the bottom of the sorting plate 34, and an immature rice removal net 4 is provided at the bottom of the brown rice flow gutter 43.
6, the brown rice flow gutter 43 is partially overlapped with the bottom position of the lowermost sorting plate 34, and the brown rice flow gutter 43 is fixed to the sorting plate 34 side. Therefore, (a) Immature rice in the brown rice taken out from the brown rice outlet 39 can be efficiently removed by the horizontally swinging immature rice removal net 46.

(b) Since the width of the immature rice removal net 46 can be made considerably wide without increasing the size of the hulling device due to its structure, immature rice removal can be performed satisfactorily.

C. Since the unripe rice removing net 46 swings horizontally, the grains do not dance, so that sorting is performed well.

This effect is achieved.
