Abstract

PURPOSE:To improve sorting efficiency by providing vertical grain sorters around a hulling part and rockable sorting devices. CONSTITUTION:Hulled grains of rice are dropped into a hulled rice receiving through 12 and then into a first vertical grain sorter 39 to undergo a primary fine grain sorting through elongated selecting holes. The rice is then sent into a second vertical grain sorter 41 to undergo a secondary fine grain sorting. The rest of the grains is supplied into an elevator 31 and then into each of rockable sorting plates 16. The unpolished rice flows in a lateral direction on the upper rocking side 16c of the rockable sorting plate 16, unhulled rice flows down to the lower rocking side 16d and, between these grain streams, the grain remaining unseparated flows, whereby the grains are classified into three kinds, unpolished rice, mixed grains and unhulled rice. The unpolished rice taken out from an unpolished rice uptake part 21 undergoes the fine grain sorting by a vertical grain sorter 38 and is transferred into an unpolished rice elevator 29 for discharge from the machine. This permits the sorting accuracy to be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a rice hulling sorter equipped with a hulling section, a wind sorting section, and a swinging sorting device.

[Prior Art and Problems to be Solved by the Invention] There is a rice hulling sorting machine that is equipped with a rice cracking section, a wind sorting section, and a swinging sorting device. This invention aims to remove the small rice generated during the hulling and sorting work of such a hulling and sorting machine, by removing the small rice both during the hulling and sorting process and after the hulling work is completed, and by performing a swing sorting process. This aims to improve sorting efficiency and sorting accuracy by reducing the amount of grains to be sorted by the device, and to streamline the removal of small rice after these sorts.

[Means to solve the problem]

The technical means of the present invention for solving this technical problem is the removal part 1. A wind sorting section 2 that wind-sorts the rice that has fallen off from the shearing section 1 and a swinging sorting device 3 that sorts the rice that has fallen through the wind selection section 2 are sequentially arranged from above to below. , these removal parts 1. Around the wind sorting section 2 and the swinging sorting device 3, there is a vertical grain sorting machine 38 for brown rice grains that re-sorts the brown rice grains sorted by the swinging sorting device 3, and rice grains sorted by the wind sorting section 2. Vertical grain sorters 39 for mixed grains that sort subsequent mixed grains are arranged near each other, and the small grains discharged from these vertical grain sorters 38 and 39 are transported by a single small grain conveying device 54. The structure of the hulling and sorting machine is characterized in that after the grains are conveyed to one side, they are taken out of the machine by a small grain lifting machine 56.

[Operation and effect of the invention]

The scraped rice that has been rubbed off in the shedding section 1 is wind sorted in the wind sorting section 2 below, and the mixed rice after wind selection is supplied to a vertical grain sorter 39 for mixed grains. The mixed grains with relatively large grains are supplied to the oscillating sorter 3 and subjected to a sorting action, and the brown rice grains sorted by the oscillating sorter 3 are further passed through a vertical grain sorter 38 for brown rice piles. After the small rice is further sorted and removed, it is taken out of the machine. On the other hand, the small grains sorted by the vertical grain sorter 38 for brown rice and the vertical grain sorter 39 for mixed grains are transported to one side by a single small grain conveying device 54, and then the small grains are fried. It is taken out of the machine at machine 56.

In this way, the rice that has been hulled in the hulling section 1 is transferred to the wind sorting section 2.
The mixed grains are air-sorted first, and then small grains are first removed by a vertical grain sorter 39 for mixed grains, and then supplied to the swinging sorter 3, so only the amount of grains removed is , the amount of grains to be sorted in the oscillating sorting device 3 is reduced, and the sorting efficiency can be increased.

In addition, the brown rice grains after being sorted by the oscillating sorter 3 are sorted again by the vertical grain sorter 38 for brown rice piles to remove small grains, and the accuracy of small grain sorting is improved. Since the small grains are taken out after sorting by the type grain sorter 38 and 39, they are transported to one side of the machine body by a single small grain conveying device 54, so that the removal of the small grains from the machine can be simplified. It is.
