Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an apparatus for sorting branch stalks of a country elevator (large-scale joint paddy drying and preparing facility).

[Conventional technology]

In a country elevator, dried and partitioned paddy (fir) is temporarily sold to the government, stored in a storage silo, and then padded (fir) as needed for shipment.

In the selling process, the paddy dried to a predetermined water content (for example, 15%) is air-selected by a wind separator, and then sent to a sorter 66 including indent cylinders (see FIG. 5) provided in a plurality of stages. . The indent cylinder 67 is rotatably suspended by an electric motor (not shown). Inside the indent cylinder 67, a small-grain trough 68 having an open upper end is provided.
Is rotatably suspended. A screw conveyor 69 for small particles is provided at the bottom of the small particle receiving trough 68 for conveying small particles.
Reference numeral 70 denotes a pot-shaped recess formed on the inner wall surface of the indent cylinder 67.

The paddy supplied to the rotating indent cylinder 67 is
While being agitated, the particles are fitted (canned) one by one into the concave portion 70 and lifted in the rotation direction. Branches with a large grain length fall quickly, and deficient (ぷ) grains and rice grains with a short grain length are lifted upward and fall into a small grain trough 68. The paddy in the small-grain trough 68 is fed laterally by the small-grain screw conveyor 69, supplied to the next indent cylinder, and sorted into hulls and rice hulls. Adjustment of the sorting state of the sorting machine is performed by rotating the small-grain receiving trough 68 as shown by the arrow.

However, in the conventional sorting machine as described above, the sorting state of the paddy to be sorted cannot be directly seen, and it is determined by the sorting grains discharged from the small-size screw conveyor to the outside of the machine, and the receiving gutter is rotated. To adjust the sorting condition. Therefore, there was a problem that it was difficult to perform fine adjustment and it was not possible to completely remove the branch stalk. In addition, since the sorting is performed by rotation, there is a problem that if the flow rate is increased, the paddy does not fit into the concave portion and the sorting becomes impossible.

To the sorter 24 via.

Hereinafter, a specific operation in the above embodiment will be described. The raw rice fed into the receiving hopper 2 is supplied to the roughing machine 3 via the fryer 4, and cuts, contaminants and immature grains are sorted and removed. The paddy from which contaminants and immature paddy have been removed is supplied to a weighing machine 7 via a three-way switching valve 5 and a crushing machine 6 and weighed.
, And are distributed and put into each of the receiving tanks 12.

Although the paddy temporarily stored in the receiving tank 12 receives ventilation by a blower to prevent deterioration, when the paddy is filled in an appropriate amount, the paddy flows out of the discharge port onto the discharge swing belt conveyor 20, and is subjected to grain-lifting. It is supplied to the dryer 22 through the dryer 21 and the two-way switching valve 13. The paddy flowing down in the dryer 22 is exposed to hot air to remove moisture from the rice husk on the surface. The rice husks, which have passed through the dryer 22 and the rice husks have been dried to a certain extent, are put into vacant tempering tanks 16 and 18 by a graining machine 23 and a carry-in conveyor 19 (flow conveyor or the like). While being left in the tempering tanks 16 and 18 for several hours, the moisture of the brown rice migrates to the rice hulls and equilibrates (temper), at this point it flows out of the discharge port and is again put into the dryer 22 to be dried. , And the dried paddy is transported to the tempering tank 18.

Drying is performed in this manner, and when the unpolished moisture reaches a moisture content of, for example, 18%, the paddy is charged into the storage silo 17 and stored until the harvesting receiving period ends. Then, when the receiving period is over, the paddy in each storage silo 17 is sequentially discharged, and is again subjected to the drying operation by the dryer 22 and the refining operation by the tempering tanks 16 and 18 to obtain a water content of 15%.
Dried until

When the drying is completed, the finished paddy will be sold to the government through a selective process. That is, after the paddy flowing out of the outlet of the storage silo 17 containing the required paddy is supplied to the roughing machine 3 through the two-port switching valve 13 and air-selected,
In order to remove threshing (brown rice) and branch stalks contained in the paddy, it is supplied to the sorter 24 via the three-way switching valve 5.

The paddy put into the supply tank 42 of the sorter 24 is
And are equally distributed by the supply gutter 44 and are uniformly supplied to the respective sorting boards 34. On the other hand, since each sorter 34 is given a swinging motion by the eccentric wheel 37, the rod 38 and the swinging arm 36,
Threshing with a relatively large specific gravity is swung toward the upper slope by the rough surface of the sorting board 34 (see FIG. 4). The paddy which is deflected and occupies a large part forms a layer flowing through these intermediate portions, and the shedding is divided by the shedding partition 46 and falls into the cover 45. At this time, since the threshing outflow on-off valve 63 is open, threshing is performed by the threshing outflow trough 49.
Is discharged into the threshing tray 53. This shattering is unnecessary when selling the paddy to the government, and furthermore, it is discarded because it has passed through the dryer 22 many times and has suffered damage such as cracks in the trunk. On the other hand, the branch stalks on the lower side of the slope are separated by the paddy partition plate 48 and fall into the paddy outflow gutter 52,
At this time, since the switching valve 62 is tilted rightward in FIG. 2, the branch stalk is guided by the switching valve 62 and discharged into the branch stalk receiving trough 59. The branch stalk in the branch stalk trough 59 is sent to the degrading machine 65 via the graining machine 64, and after removing the branch stalk with the degrading machine 65,
It is sent to the roughing machine 3 via the graining machine 4. The paddy that has been wind-selected by the roughing machine 3 is re-sorted by the sorting machine 24 via the switching valve 5 and then returned to the storage silo 17 or the like as a product.

On the other hand, a large amount of paddy flows out between the degranulation partition plate 46 and the rice partition plate 48, and falls in the brown rice outflow gutter 50 and the mixed grain outflow gutter 51. At this time, since the switching valves 60 and 61 in both the outflow gutters 50 and 51 are both tilted to the right in the figure, the paddy is supplied to the switching valves 60 and 61.
And discharged into the paddy gutters 55 and 57. Paddy gutter 55,57
The paddy in the pool is merged and supplied to the weighing machine 7 by the fryer 6, and after measuring the weight, the silo is stored as rice sold by the government.
It will be stored at 17.

When the paddy thus stored in the storage silo 17 is shipped via the preparation process, the government-sold rice in the storage silo 17 is supplied to the roughing machine 3 through the two-way switching valve 13. After the wind selection, the three-way switching valve 5 is switched and supplied to the hulling machine 25.
The polished rice (mixed grains) from which 80 to 90% has been removed by the unrolling of the huller 25 is put into the supply tank 42 of the sorter 24. Then, each sorter 34 is provided by an equalizer 43 and a supply gutter 44.
The rice is evenly supplied to rice, excluding paddy in the polished rice and extracting only brown rice. That is, among the rice seeds supplied on the oscillating sorter 34, brown rice having a relatively large specific gravity is swung upward by the rough surface, and rice paddy having a relatively small specific gravity glides over the brown rice to lower the inclined rice. It drifts to the side, and mixed grains of brown rice and paddy form a layer in the middle. At this time, the threshing outflow gutter opening and closing valve 63
Closes the threshing outflow gutter 49, the brown rice outflow gutter 50, the mixed grain outflow gutter
Each of the switching valves 60 to 62 of the paddle outflow gutter 51 and the rice outflow gutter 52 is tilted to the left side in the drawing, whereby the brown rice flowing out between the brown rice partition plate 47 and the threshing partition plate 46 is partitioned into the threshing partition plate 46. The brown rice flows into the brown rice outflow gutter 50 by being guided by the graining outflow gutter opening / closing valve 63 and is guided by the switching valve 60 to be discharged into the brown rice gutter 54. The paddy on the lower side of the slope is separated by the paddy partition plate 48, flows out into the paddy outflow gutter 52, is guided by the switching valve 62, and is discharged into the paddy receiving gutter 58, and is used in the graining machines 64, 4,
After passing through the roughing machine 3 and the three-way switching valve 5, the hulling machine 25 is removed again. Further, the mixed particles flowing out between the brown rice partition plate 47 and the paddy partition plate 48 are guided by the switching valve 61 to receive the mixed particle trough.
It is discharged into 56, returned to the supply tank 42 by the graining machine 41, and sorted again by the sorter 34.

The brown rice in the brown rice trough 54 is supplied to the grain sorter 27 via the graining machine 26, and is subjected to grain size sorting. It is weighed by the weighing machine 30 via the graining machine 9 and the three-way switching valve 29 and packed in the flexible container bag 31 or weighed by the weighing machine 30 and sewn by the sewing machine 33 to be shipped.

〔The invention's effect〕

According to the apparatus for sorting branch-ember grains of a country elevator according to the present invention, a branch of a rocking sorter that forms a shedding layer on a higher slope side, a branch-sheaf layer on a lower slope side, and a paddy layer therebetween in the sorting machine. The outflow gutter of the stalk is connected to the sorting board via a degrading machine, so that the sorting state of the selected paddy can be judged directly with the eyes, and adjustment can be easily performed by the partition plate. The grains can be completely removed,
Even if the flow rate is increased, the sorting ability is not reduced.

In addition, since the paddy from which the branch stalks have been removed by the demolding machine is re-sorted, it is possible to finish the paddy completely.
