Abstract

PURPOSE:To remove ear-attached grains perfectly by connecting a gutter for carrying the ear-attached grains away to a sorting disk through an ear removing machine in shaking sorting apparatus where a layer of hulled grains, a layer of ear-attached grains, and a layer of unhulled grains are formed in an elevated part, a low part, and an intermediate part, resp., in a declined sorting disk. CONSTITUTION:After discharged from a storage silo are winnowed by a rough sorting apparatus, they are supplied uniformly to each sorting disk 34 of the sorting apparatus 24. Each sorting disk is composed of a rough surface and shaken up and down obliquely. Owing to this, hulled grains with relatively high specific gravity are gathered swingingly toward a slanting upper part of the sorting disk 34, ear-attached grains with relatively small specific gravity bias flow toward a slanting lower part, and unhulled grains which occupy major part form a layer running in the intermediate part. The ear-attached grains in the slanting lower part drop to a chaff carrying out gutter 52 by divided by an unhulled grain partitioning plate 48, led so as to be discharged from an ear-attached grain receiving gutter 59 by a switching valve 6 2. Then, the ear-attached grains are sent to a beard removing machine by a country grain elevator, and after grain ears are removed here, they are sent to the rough sorting apparatus and winnowed. Winnowed unhulled grains are sorted again by the sorting apparatus 24, and sorted unhulled grains from which ear-attached grains are completely removed are returned to a storage silo.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a branch grain sorting device for a country elevator (large communal paddy drying and preparation facility).

[Conventional technology]

At the country elevator, the dried paddy is sold to the government and then stored in storage silos, and if necessary, the paddy is hulled and shipped.

In the selling process, the paddy dried to a predetermined moisture content (for example, 15%) is sorted by a wind sorter and then sent to a sorter 66 consisting of multiple stages of indented cylinders (see FIG. 5). The indented cylinder 67 is powered by an electric motor (
(not shown), and inside the indented cylinder 67 is a small particle receiving trough 68 with an open upper end.
is hung horizontally so that it can rotate. A small particle screw conveyor 69 for conveying small particles is provided at the bottom of the small particle receiving trough 68, and reference numerals 70 are four pot-shaped parts formed on the inner wall surface of the indented cylinder 67.

The paddy supplied to the rotating indented cylinder 67 is
While being stirred, the grains fit into the recess 70 one by one and are lifted in the direction of rotation. The large grains fall quickly, and the dehulled grains and chaff grains, which are short in length, are lifted upward and fall into the small grain receiving trough 68. The paddy in the small-grain receiving trough 68 is transported laterally by a small-grain screw conveyor 69, and is supplied to the next indented cylinder where it is sorted into dehulled grains and paddy grains. In addition, the adjustment of the sorting state of the sorting machine is based on the small particle amount ti! 6
This is done by rotating 8 in the direction of the arrow.

However, in the conventional sorting machine as described above, it is not possible to directly see the sorting condition of the paddy to be sorted, and it is judged by the sorted grains discharged outside the machine from the screw conveyor for small grains.
Sorting conditions were adjusted by rotating the receiving gutter. Therefore,
There was a problem in that it was difficult to make fine adjustments and it was not possible to completely remove the branch grains. Furthermore, since sorting is performed by rotation, there is a problem in that when the flow rate is increased, the rice grains do not fit into the recesses, making sorting impossible.

[Problem that the invention seeks to solve]

The purpose of this invention is to solve the above-mentioned problems and to provide a separator that can completely remove the semen grains by simple adjustment and that does not reduce its sorting ability even when the flow rate is increased. .

Means for Solving Problem C] In order to achieve this object, the present invention has the following configuration.

A sorting board with a rough surface is tilted so that it can freely swing back and forth diagonally up and down, and a layer of removed grain with relatively high specific gravity is placed on the high side of the slope, and a bed grain layer with relatively low specific gravity is placed on the lower side of the slope. A movable partition plate is provided between each layer of the oscillating sorter which forms a paddy layer between them, and below the partition plate, drains for removing rod grains, husk grains, and paddy are provided, respectively, to drain out the husk grains. The gutter is connected to the sorting board via a de-awning machine which removes the branches and stems.

[For production]

The sorted paddy supplied to the sorting plate of the oscillating sorter is oscillatingly sorted, and the unhulled grains included in the majority of the paddy are discharged from the unhulled grain discharge trough on the highest side of the slope, and then the unhulled grains contained in the majority of the paddy are discharged from the unhulled grain discharge trough on the highest side of the slope. The husk grains are discharged from the husk, and the paddy is discharged from the paddy granule discharge trough. Then, the discharged chaff grains are sent to an awn remover to remove the chaffs, and the paddy grains from which the chaffs have been removed are again supplied to the sorting board and re-sorted.

Note that the sorting machine 24 having the above configuration may be formed symmetrically with the eccentric ring 37 in between.

In addition, the branch grain receiving trough 59 is passed through the grain lifting machine 64 to the awning machine 65.
The awning e165 is sent to the grain lifting machine 64, the rough sorting machine 3, and the sorting machine 24 via the three-way switching valve 5.

Hereinafter, specific operations in the above embodiment will be explained. The raw rice put into the receiving hopper 2 is supplied to the coarse sorter 3 via the grain fryer R4, and cut ears, foreign grains, and immature grains are sorted out and removed. The paddy from which foreign grains and immature grains have been removed is supplied to the weighing machine a7 via the three-way switching valve 5 and the grain lifting machine 6, and then weighed.
0, and are distributed and put into each cargo receiving tank 12.

The paddy temporarily stored in the receiving tank 12 is ventilated by an air blower to prevent deterioration in quality. However, once a suitable amount of paddy is loaded, it flows out from the discharge port onto the discharge belt conveyor 20 and is transferred to the grain lifting machine. 21 and the two-way switching valve 13 before being put into the dryer 22 .

The rice flowing down the dryer 22 is exposed to hot air, and the moisture in the rice husks on the surface is removed. Dry I! After passing through 22, the paddy whose husks have dried to some extent is transferred to a grain lifting machine 23 and a carrying conveyor 19.
It is placed into an empty tempering tank 16°18 by a flow conveyor or the like. While the brown rice is left in the tempering tank 16°18 for several hours, the moisture in the brown rice transfers to the rice husks and is balanced and tempered. was given,
After drying, the rice grains are transported to the tempering tank 18, and the process is repeated.

Drying is carried out in this way, and the moisture that does not change the quality of the paddy, for example, 18
%, they are put into the storage silo 17 and stored until the end of the receiving period during the harvest season. When the receiving period ends, the paddy in each storage cage 017 is discharged one after another and is repeatedly subjected to the drying action by the dryer 22 and the tempering action by the tempering tank 16.
until dried.

Once drying is complete, the finished paddy goes through a selection process and is sold to the government. That is, the paddy flowing out from the discharge port of the storage silo 17 containing the required paddy is supplied to the coarse sorter 3 via the two-way switching valve 13 and screened, and then the unhulled paddy contained in the paddy is removed. In order to remove grains (brown rice) and branch grains, the rice is supplied to a sorter 24 via a three-way switching valve 5.

The paddy put into the supply tank 42 of the sorting [24] is divided equally by the equalizer 43 and the supply gutter 44, and is evenly supplied to each sorting 134. On the other hand, each sorting board 34 has an eccentric wheel 37,
Since the rod 38 and the swinging arm 36 provide a swinging motion, the unmolded grains with relatively high specific gravity are transferred to the sorting board 3.
4 is swayed to the upper side of the slope by the rough surface (see Figure 4), and the stalk grains, which have a relatively low specific gravity, float to the lower side of the slope while floating above the dehulled grains and paddy, and occupy the majority of the grain. The paddy forms a layer flowing in the middle of these layers, and the dehulled grains are separated by the dehulled grain partition plate 46 and fall into the cover 45.

At this time, since the drain valve 63 is open, the drained particles flow from the drained particle outflow gutter 49 to the floating particle receiving gutter 53.
discharged inside. This dehulled grain is unnecessary when it is sold as paddy to the government, and moreover, it has been passed through the drying process many times and has suffered damage such as cracking, so it is discarded. The branch grains on the lower side of the inclination are partitioned by the rice partition plate 48 and fall into the paddy outflow channel 52. At this time, since the switching valve 62 is tilted to the right in FIG. The ink is guided by the switching valve 62 and discharged into the ink receiving trough 59. The twigs in the twig receiving trough 59 are sent to the awning machine 65 via the grain frying machine 1164, and after the twigs are removed by the awning machine 65, they are sent to the rough sorting machine 3 via the grain lifting machine 4. It will be done. The paddy wind-screened by the coarse sorter 3 is re-sorted by the sorter 24 via the switching valve 5, and then returned to the storage silo 17 etc. as a product.

On the other hand, a large amount of paddy flows out from between the grain removal partition plate 46 and the paddy partition plate 48, resulting in brown rice flow tJ50 and mixed grain flow t! 1
Fall within 51. At this time, since the switching valves 60.61 in the dual flow 150.51 are both tilted to the right side in the figure, the paddy is guided by the switching valves 60.61 to the paddy receiving trough 55.
57. The paddy in the paddy receiving troughs 55 and 57 are combined and supplied to the weighing machine 7 by the grain lifting machine 6, and after being weighed, they are stored in the storage silo 17 as rice sold by the government.

When the paddy stored in the storage silo 17 is to be shipped after the preparation process, the rice sold by the government in the storage silo 17 is supplied to the coarse sorter 3 through the two-way switching valve 13. After wind sorting, the three-way switching valve 5 is switched to supply the rice to the huller 25. The milled rice (mixed grains) from which 80 to 90% of the grain has been dehulled by the dehulling rolls of the huller 25 is fed into the supply tank 42 of the sorter 24. Then, the equalizer 43 and the supply gutter 44
The unpolished rice is evenly supplied to each sorting board 34, removing the paddy from the polished rice and extracting only brown rice. That is, among the unhulled rice fed onto the oscillating sorting board 34, brown rice with a relatively high specific gravity is shaken up to the upper side of the slope by the rough surface, and paddy with a relatively low specific gravity slides on the brown rice and moves to the lower side of the slope. It drifts to the side, and in the middle there is a layer of mixed grains of brown rice and paddy. At this time,
The dehulled grain outflow gutter opening/closing valve 63 closes the dehulled grain outflow gutter 49, and the switching valves 60 to 62 of the brown rice outflow gutter 50, the mixed grain outflow gutter 51, and the paddy outflow tube 52 are tilted to the left in the figure. As a result, the brown rice flowing out between the brown rice partition plate 47 and the grain removal plate 46 is partitioned by the grain removal plate 46 and flows out, and is guided to the IIR+1 grain outflow gutter opening/closing valve 63 and the brown rice flows out 150. The brown rice flowing therein is guided by the switching valve 60 and discharged into the brown rice receiving trough 54. The paddy on the lower side of the slope is
The paddy is partitioned by the paddy partition plate 48 and flows out into the paddy outflow channel 52, and is guided by the switching valve 62 and discharged into the paddy receiver [58].
Fried grains! After passing through the 1I64, 4, rough sorting 113 and three-way switching valve 5, the rice is dehulled again in the huller 25. In addition, the mixed grains flowing out between the brown rice partition plate 47 and the paddy partition plate 48 are guided by the switching valve 61 and discharged into the mixed flour receiver 56, and are returned to the supply tank 42 by the fried grains 141 and recycled again. They are sorted by a sorting board 34.

The brown rice in the brown rice amount tI154 is supplied to the grain sorter 1127 through the grain lifting machine 26 and is sorted by grain thickness, and the grains having grain thickness above a certain level are passed through the stone removal machine 28 to remove stones, and then sent to the grain sorting machine 1127. 9. It is weighed with a weighing machine 30 via the three-way switching valve 29 and packed into a flexible container bag 31, or it is weighed with the weighing machine 30 and the bag opening is sewn with a sewing machine 33 before being shipped.

[Effects of the Invention] According to the country elevator chaff grain sorting device of the present invention, the dehulled grain layer is formed on the higher inclined side of the sorting board, the chaff grain layer is formed on the lower inclined side, and the grain layer is formed between them. Since the outflow gutter of the dynamic sorter is configured to communicate with the sorting board via the awning machine, the sorting condition of the paddy to be sorted can be judged directly, and adjustments can be made easily using the partition plate, making it easier to sort. It is possible to completely remove the husks from the rice, and the sorting ability is not reduced even if the flow rate f is increased.

In addition, since the paddy is re-sorted from which the stems have been removed by the awning machine, it is possible to finish it into perfectly sorted paddy.
