Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is based on a system in which several sorting disks each having a large number of pot holes formed in the sides, large enough to fit brown rice, are mounted on a horizontal axis at intervals. A brown rice receiving trough is diagonally installed on the side of the sorting disk to take out the brown rice lifted up by the pot hole, and a mixed rice supply port is installed on one side of the machine, and a feed port for unpaddy is placed on the other side. This invention relates to a disk-type rotary sorting device and sorting disk that is configured with a discharge port.

(B) Conventional technology In the disk-type rotary sorting device described in the previous section (a), the several sorting disks rotatably installed in the body of the machine are conventional, for example, in Japanese Patent Laid-Open No. 36 -1366
The sorting disk of the disk-type rotary sorting device disclosed in this publication has a circular disc shape. Since the distance between the machine body and the periphery of the sorting disk is relatively small, the flow of rice from the supply port to the discharge port of the supplied rice can be smoothly transferred. Therefore, the thickness of the fluidized bed of the mixed rice is not stable from the time of supply to the time of discharge, and the sorting action is poor, making it difficult to improve the sorting efficiency.

In order to solve this conventional drawback, the present invention aims to smooth the flow of mixed rice by promoting the fluid transfer to the discharge side where the supply is known, and to stabilize the thickness of the fluidized bed of mixed rice to ensure an equal sorting effect. It was created with the aim of improving sorting efficiency by making it more efficient and efficient.

2) Means for Solving the Problems Therefore, the present invention is based on the invention, in which several sorting disks with many potholes formed on the sides are mounted on a horizontal shaft (at intervals of τ) and can be rotated. The sorting disk of a disk-type rotary sorting device is constructed by installing a brown rice catcher diagonally in the 91j section of the sorting disk, and having a supply port on one side of the machine and a discharge port on the other side. The aim is to achieve the purpose stated in the previous section (c) by configuring the system in a specific manner.

That is, several parts of the periphery of the sorting disk are cut off,
After the cutout, the cutout portion is made thinner as it approaches the periphery, and the discharge port is formed into a slope, and the position of the cutout portion of the adjacent sorting disk is determined when viewed from the horizontal axis direction. It is configured by shifting and pivoting.

(E) Function Then, the mixed rice of brown rice and paddy supplied from the supply port into the machine body is deviated in the direction of rotation by the rotation of each sorting disk, forming a fluidized bed. The brown rice in the mixed rice reaches a high position through the pot hole formed on the side of the sorting disc. The paddy that is lifted up and falls down is stopped by the brown rice receiving trough where it flows down and is taken out.The paddy that cannot be lifted up through the pot hole reaches the discharge girder and is taken out of the machine from the outlet and is sorted into brown rice and paddy. It is.

In this case, due to the cutouts formed at several places on the periphery of the sorting disc, the distance from the inner peripheral wall of the machine becomes large, making it easier for the mixed rice to pass through toward the discharge side. The slope of the discharge channel applies pressure toward the peripheral wall of the machine body of the discharge channel, and the flow of mixed rice to the discharge channel is promoted. In addition, at this time, the positions of the cutout parts of the adjacent sorting disks are shifted when viewed from the horizontal axis direction, and the pressure applied to the discharge side at the cutout part is the cutout part of the adjacent sorting disk. As a result, pressure is continuously applied to the discharge side, the supply of mixed rice is known, and the flow transfer to the discharge side becomes smooth, and the fluidized bed thickness is stabilized while being sorted by the pot hole. be.

(F) Embodiment The present invention will be explained below with reference to embodiment diagrams. This example diagram shows the disc-type rotary sorting device according to the present invention applied to mixed rice sorting in a huller. Therefore, I will also write about this rice hulling machine as a whole.

As shown in Fig. 3, this rice hulling machine has a vertically elongated rectangular box body (1), which includes a hulling section (2), a wind sorting section (3), and a disc-type rotary sorting device (A) according to the present invention. The hulling section (2) consists of a rice tank (4), a pair of dehulling rolls (5), etc., and is located in the middle of the box (1). The wind sorting section (3) is located below the hulling section (2),
This system separates the rice that has fallen off after being crushed into rice husks and mixed rice, and supplies the mixed rice to the disk-type rotary sorting device (A). ) and a suction/dust removal fan (9), etc.
) A mixed rice thrower 01 is connected to lift the mixed rice to a disk-type rotary sorting device (A).

The above-mentioned disk type rotary sorting device (A) d Horizontal crosspiece
A supply port aZ is opened on one side of 1υ, and a discharge port a3 is opened on the other side, and the upper end of the mixed rice thrower a1 is exposed to the supply tube 04 connected to the supply port lIz. The paddy taken out from this discharge port (13) is returned to the paddy tank (411'C) of the hulling section (2) during the reduction period d5.

And inside this aircraft αυ, there is a direction V from one side to the other side Y? - The horizontal side is rotatably mounted horizontally, and this horizontal axis Oa
A pot with holes (171) large enough to fit the brown rice on both sides [+10 (iga) (
+++b) (+t c) are mounted on the shaft at appropriate intervals, and these sorting disks Q9 (+8→(i8b)(I8
A brown rice receiving gutter 09 is inserted in a slanted manner into each side of c), and the lower end of this brown rice receiving gutter 09 is extended downward and communicates with the brown rice sorting section ■ with a brown rice removal unit ■.

In addition, a suction dust exhaust fan (9) in the air selection section (3)
The suction side of the box body (1) is connected to the brown rice sorting section 311 and the machine body qIl through a vertical air passage (■) formed in the box body (1), so that fine dust inside the machine body 1 can be sucked from inside the machine body αυ. It is configured to suction and discharge the brown rice, and to finish the brown rice in the brown rice sorting section 2υ.There is a supply port at the bottom of the machine σD, and a residual grain discharge port is formed along the side of the discharge port α3. An opening/closing lid is pivotally attached to the grain outlet.

Next, the aforementioned sorting disk (II (+sa)Qgb
)(+ac) To explain K in detail with reference to Figs. 1 and 2, this selection disk αIQ (8a) G8b) G8c
) is constructed in the same way, and the cutout is made by cutting out four parts of the periphery in a straight line, and forming a slanted part in the straight line after cutting, which becomes thicker as it gets closer to the periphery. The sorting disc (18C) for the final discharge
This sorting disk 1 (OQaa) (ub) Qgc) is pivoted at appropriate intervals along the discharge side, with the slope of the disk facing toward the discharge port OJ, except for the
As shown in Figures 5), 2), and 3) of Fig. 2, examples of the cut portions are shifted and attached to the shaft when viewed from the 0 direction of the horizontal shaft opening.

That is, the notch is shifted by 45 degrees so that the cutout part of the sorting disk 03 on the most feeding side and the adjacent sorting disk (I8a) are separated from each other by 45 degrees. However, as can be seen from the comparison of the removed parts (b) and (c) of the sorting disk (18a) of the case and the next sorting disk (Igb), there is a 45-degree shift, and this sorting disk (18b) and the first discharge are different. Wan's sorting disk 08C) Melt (
C) It is mounted on the shaft at a 45° angle so that it does not come off.

In addition, the sorting disk (=8) (18a) (1
8b) Only the slope d of (18c) is directed toward the supply port ■.

Therefore, the rice supplied to the paddy rice harvester (4) is scraped off by the huller removal unit (2), and the scraped rice is wind-selected in the wind selection unit (3) to remove the chaff and husks. The mixed rice of brown rice and paddy enters the mixed rice thrower (8), is lifted up by the mixed rice thrower αO, and is supplied from the supply cylinder I into the machine body αυ.

Each sorting disk (L!D(u+a)(t8b)(u+c)
), the supply is known, and the flow moves toward the discharge side, forming a fluidized bed (2L), and this flow. During the transition, the brown rice in the mixed rice was lifted up into the pot hole (+71 lri), fell onto the brown rice receiving gutter α9, and flowed down to the brown rice wind selection section Qυ for finishing wind selection, and then the brown rice removal chute ■ to the machine. It was taken out and the brown rice receiving channel u9 was taken out by the pot hole 0'71!
The paddy that cannot be lifted up until then is transferred to the top of the discharge column, passes from the discharge port σ3 to the reduction cylinder LI51, is turned over to the paddy tank (4), and is slid down again.

In this case, each sorting disk (
The cutouts λ° formed at several locations on the periphery of I81θ8a) (Igb) reduce the distance from the inner circumferential wall of the body 1111, making it easier for the mixed rice to pass through and move toward the discharge side. In addition, the trailing side of the slope (■) formed at this cutout section allows pressure to be sent toward the inner circumferential wall of the machine (III) on the discharge side, causing the mixed rice to flow toward the discharge side. In addition, each sorting disk +110 (King ga) (18) (18a) (18b
) (18c) The positions of the cutout parts ■ are shifted by 45 degrees from each other, so if pressure is applied to the discharge side at the cutout part ■, the discharge will be caused by a chain reaction due to the cutout part of the sorting disc of the hook. As the pressure is applied to the drain side, the flow of the mixed rice to the discharge side becomes smooth, the thickness of the fluidized bed becomes stable, and it is sorted by the pot hole (17).

The cut out part of the sorting disk (18c) at the end of the set and discharge side
Since the slope of ■knee i supply port t+4+ is facing towards the side,
This sorting disk (18C) and sorting disk (+gt)
) is pushed back by the slope of the mixed rice flowing between the holes in the pot hole 4? The lifting action 'd by l is sufficiently performed.

In addition, Figs. 4 to 6'ri show other examples of the above-mentioned cutout part α(), and this cutout part (26a) There are four slopes (aaQ) formed in the semi-circular arc section when viewed from the horizontal axis LIG direction so that the semi-circular arc section reaches the periphery and becomes thinner. The slope (25a) of this is also formed so as to be inclined in the direction of the turning force in the direction of the arrow (P) so that pressure is applied to the discharge side.

The other configurations shown in FIGS. 4 to 6 are the same as those shown in FIGS. 1 and 2, so the same reference numerals are given to the respective drawings and the explanation thereof will be omitted.

(G) Effects of the Invention As explained above, the present invention has a structure that takes the means described in item () above, so that the mixed rice fed into the machine is distributed over the number of peripheral parts of the sorting disk. Due to the cutout section, the distance from the internal peripheral wall of the machine becomes large, making it easier to pass through toward the ejection side, and the slope beside the ejection port formed in this cutout area makes it easier to pass through the ejection side. Pressure is applied to the inner circumference of the machine to promote the flow of the mixed rice to the discharge side, and furthermore, the position of the cutout section of the adjacent sorting disk is shifted when viewed in the horizontal direction. Therefore, pressure is applied to the discharge side at the cutout part, and pressure is applied to the discharge side in a chain by the cutout part of the adjacent sorting disk, and the flow transition is smooth. Therefore, by stabilizing the thickness of the fluidized bed of mixed rice, the sorting action by the holes in the pot can be made even and vigorous, which has the advantage of improving the sorting efficiency.
