(Problems to be Solved by the Invention) In the above-mentioned known Japanese Patent Application Laid-Open No. 55-88861, a hulling unit is provided on a wind selection unit, and a grain selection unit is further provided thereon. However, the height of the whole becomes high, and the bucket elevator for circulating the hulling is inevitably high, so that the material used becomes thick and thick, so that it cannot be inexpensive. In addition, because it is a structure that vibrates the sorting plate of the grain sorting section vigorously at the top, it must be more robust than necessary,
Even so, vibrations are generated, resulting in a rattling device.

Further, the one described in the conventionally known Japanese Patent Application Laid-Open No. 60-87862 has a hulling unit arranged in a lower part and a hulling unit and a wind selection unit provided in an upper part of the hulling unit. Since the position of the part is high, it is not possible to supply the hulling part manually, and a supply bucket elevator is provided to supply the hulling part. However, with this structure, the mixed rice discharged by the grain selection in the grain selection section must also be returned to the head of the grain selection section, and therefore, a dedicated bucket elevator for return must be separately provided. . Then, because the cost is too high, the publication discloses that the mixed rice outlet is connected to the lower part of the supply bucket elevator to make the supply bucket elevator return and also serves as a return. There is a problem that it must be performed and that the tank (reference numeral 9) is over-supplied and may be clogged immediately.

The height of the whole becomes high, and the bucket elevator for circulating the hulling is inevitably high, so that the material to be used becomes thick and thick and cannot be inexpensive. In addition, the structure in which the sorting plate of the grain sorting section is violently rocked at the uppermost portion has to be made more robust than necessary, and vibrations are still generated, resulting in a rattling device.

Further, the one described in the conventionally known Japanese Patent Application Laid-Open No. 60-87862 has a hulling unit arranged in a lower part and a hulling unit and a wind selection unit provided in an upper part of the hulling unit. Since the position of the part is high, it is not possible to supply the hulling part manually, and a supply bucket elevator is provided to supply the hulling part. However, with this structure, the mixed rice discharged by the grain selection in the grain selection section must also be returned to the head of the grain selection section, and therefore, a dedicated bucket elevator for return must be separately provided. . Then, because the cost is too high, the publication discloses that the mixed rice outlet is connected to the lower part of the supply bucket elevator to make the supply bucket elevator return and also serves as a return. There is a problem that it must be performed and that the tank (reference numeral 9) is over-supplied and may be clogged immediately.

A feeding hopper 17 of a possible height is provided, the grain selecting section 3 is disposed above the wind selecting section 1, and the swing sorting plate 4 of the grain sorting section 3 is sorted by right and left swing. On the plate surface of the rocking sorter plate 4, the hulling part side is provided with an inclined projection 7 having a low anti-hulling part side and a high hulling part side. Rice with light specific gravity
11 is distributed on the side of the hulling unit, the swing sorting plate 4 is adjustable in the horizontal direction to adjust the distribution state, and the swing sorting plate 4 is higher than the supply hopper 17 of the hulling unit 18. The paddy rice 11 distributed to the hulling part side at the position is dropped and supplied to the supply hopper 17 as it is, and the mixed rice discharged from the oscillating sorting plate 4 is moved to the head of the oscillating sorting plate 4 by the circulation bucket elevator 36. Returning to the section, the supply bucket elevator is not provided, so that the hulling device is not provided. B. The hulling unit 18 is on one side on the left and right, and the wind selection unit 1 and the grain selection unit 3 are on the other side on the left and right. Because of the arrangement, for example, as compared with a three-tiered hulling unit, wind selection unit and grain selection unit as disclosed in JP-A-55-88861, the height can be formed considerably lower, Japanese Patent Application Laid-Open No. 60-87862 or Japanese Utility Model Application Laid-Open No. 58-1
As disclosed in Japanese Patent Publication No. 08142, when compared with a device having another device below the hulling unit, there is nothing at the lower portion of the hulling unit 18, so that the upper part of the hulling unit 18 can be supplied manually. Combined with the provision of the supply hopper 17 having a height, the supply hopper 17 can be further lowered, and supply is easy.

(B) The grain sorting unit 3 is arranged above the wind sorting unit 1 and the swing sorting plate 4 of the grain sorting unit 3 is sorted by right and left swing. The mixed rice supplied to this is provided with the inclined projection 7 having a lower part side and a higher anti-hulling part side, and the mixed rice supplied thereto has a heavy specific gravity.
Numeral 10 is a rice grain having a lower specific gravity on the side of the hulling part, and rice 11 with a low specific gravity is distributed on the hulling part side. 17
Is supplied to the supply hopper 17 under the gravity flow.

C. The mixed rice discharged from the oscillating sorting plate 4 is returned to the head of the oscillating sorting plate 4 by the circulation bucket elevator 36, so the height to the head of the oscillating sorting plate 4 is not so high. The bucket elevator 36 for circulation is also a small-sized one and is a hulling device without a bucket elevator for supply in time, so that the structure is simple.

(D) Further, since a partition plate 21 for partitioning in the left-right direction is provided inside the supply hopper 17, a rice hulling device having a rice return port 23 formed on the side close to the swing sorting plate 4 is provided.
The rice can be returned to the rice return port 23 more easily than the rocking sorting plate 4.
