Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a rotary sorting plate which is open laterally and is composed of a number of pockets into which grains can be inserted.
This relates to a grain sorting device that sorts mixed rice such as paddy and brown rice by rotating a plurality of grains around a horizontal axis.

[Prior art] Mixed rice of paddy and brown rice is prepared by rotating a plurality of rotary sorting plates around a horizontal axis, each of which is open laterally and has a large number of pockets into which grains can be inserted. For example, a rotary sorting plate type grain sorting device for sorting grains, etc.
It is known from the publication No.-39671.

The pinnacle of the problem that the invention seeks to solve] This prior art combines a shedding section, a winnowing section, and a rotating sorting plate type grain sorting device to integrally constitute a hulling/sorting device. Although it has some merits in that it has been devised, it has the following problems.

■First problem This conventional device has a configuration in which a husking section is placed above the wind sorting section that wind-sorts the fallen rice, and a grain sorting device using a rotating sorting plate is placed above this husking section. Met.

In order to place a rotating sorting plate-type grain sorting device above the threshing section, which has a relatively small space, the number of rotating sorting plates is limited and the entire machine is compact, making it a relatively low-efficiency, small-sized machine. Although it may be good for small objects, it has the problem that it is not suitable for high-efficiency devices with a large number of rotary sorting plates.

■The second problem is that when multiple rotary sorting plates are provided around the horizontal axis, each of which is open laterally and has a large number of pockets into which grains can be inserted, the sorting starts from the starting end. Pockets for trapping grains were configured in the same shape toward the terminal end. For this reason, there is a problem in that the grains that are pumped up from the sorting start end to the sorting end end are grains that are a mixture of small to large grains and are sorted and taken out.

Therefore, this invention changed the shape of the pocket of the rotary sorting plate to
By changing the size from the sorting start end to the sorting end, relatively small particles can be pumped up at the sorting start side, and relatively large particles can be pumped up at the sorting end, thereby overcoming the drawbacks of conventional equipment. This is an attempt to solve the problem.

■The third problem is that by further developing the invention in item 2 and changing the size of the pocket of the rotating sorting plate from the sorting start end side to the sorting end side, it is possible to The targeted small grains are drawn up, and the relatively large grains are drawn up at the end of the sorting, and these grains of different sizes are stopped by the brown rice catching plate located at the interval between the rotating sorting plates. In order to take out the grains that flow down to the lower end of the slope using the brown rice receiving trough along the axis of the rotating sorting plate, the brown rice receiving trough is divided into multiple pieces in the longitudinal direction and the grains are taken out according to their size. In this way, the subsequent sorting of grains by size is omitted or streamlined.

■The fourth problem is that the hulling and sorting device is integrated by combining the hulling section, the wind sorting section for the fallen rice, and the rotary sorting plate type grain sorting device. The present invention aims to provide a compact hulling and sorting device by streamlining the process of feeding mixed rice after wind-selecting the washed rice to a single-rotation sorting plate type grain sorting device.

[Function and effect of the invention]

In the invention set forth in item 1, a wind sorting section having a husking section 1 and a fallen rice wind sorting path 4 for wind-selecting fallen rice, and a grain sorting device 8 of a rotary sorting plate type are installed side by side. Because of this structure, the number of rotary sorting plates is not limited by the space of the shedding section unlike in conventional devices, and the number of rotary sorting plates 9, 9. It is possible to provide a rice hulling machine equipped with a highly efficient rotary sorting plate type grain sorting device in which the number of grains can be freely increased.

By changing the size of the pockets 9b, 9b, ... from the sorting start end side to the sorting end side,
The sorting start end side has a small shape so that relatively small grains can be pumped up, and the sorting end side has a large shape so that relatively large grains can be pumped up, so from the sorting start end side to the sorting end side, Conventional devices in which pockets for trapping grains are configured in the same shape have the disadvantage that grains mixed with small to large grains are drawn up and taken out from the sorting start end to the sorting end. , which eliminates these drawbacks and allows relatively small grains to be drawn up at the sorting start end and relatively large grains at the sorting end side, and which allows small grains and large grains to be separated to some extent and taken out. It is.

In the invention of item 3, the invention of item 2 is further developed, and the one-rotation sorting plates 9, 9. Pocket 9b, 9b,...
By changing the size of the shape from the sorting start end side to the sorting end side, relatively small particles are drawn up at the sorting start side, and relatively large particles are drawn up at the sorting end side. The grains of different sizes are sorted once by the sorting plates 9, 9. Brown rice receiving plate 1 located in the interval between...
2,12. ..., the receiver is stopped, and the grains flowing down to the lower end of the slope are transferred to the brown rice receiver trough 1 along the axis of the rotating sorting plate 9.
3, the brown rice receiving trough 13 is divided into a plurality of pieces in the longitudinal direction so that the grains can be taken out according to their size.

Therefore, it is possible to omit the subsequent sorting of grains by size, or to further re-sort grains that have been classified into large or small grains, making re-sorting of grains more efficient. .

The invention of item 4 is based on the removal part 1. The wind-selecting part for the fallen rice and the rotary sorting board type grain sorting device 8 are combined to form a physical hulling/sorting device, and the grain sorting unit 8 is used to combine the grain sorting unit 8 for the fallen rice to remove the fallen rice from the hulling unit 1.
