Description

[Detailed description of the invention] The present invention relates to a rice hulling device.

More specifically, a dehulling part (hulling part) for shedding the paddy grains, a sorting part for sorting mixed rice (surichi rice) consisting of dehulled (brown rice) and unhulled rice (paddy grains);
Equipped with a rice sorter that sorts the grain size of ungrained (brown rice),
Regarding improvements to a hulling device in which grains in mixed rice that has been deprocessed in a hulling section are sorted in a sorting section, and the grains are taken out as fine grains with uniform grain size through a rice sorter. .

The hulling device configured as described above can perform a series of operations in succession, including processing of unhulled rice, sorting of scraped rice (mixed rice), and grain size sorting of threshed rice (brown rice). However, there is a problem that the scope of use is limited to rice hulling work and the operation rate is low.

The present invention was made in order to solve this problem, and the hulling device of the above-mentioned form is effective not only for grain size selection processing of brown rice but also for grain size selection processing of other grains such as wheat. The purpose is to make it possible to improve the operating rate by making it possible to use it for a long time.

For this purpose, in the present invention, a dehulling part (hulling part) for removing the paddy grains, and a dehulling part (hulling part) for removing the paddy grains, and
A sorting section that sorts the mixed rice with unshelved rice and unshelved rice (hull grains), a rice sorting machine that is installed so as to be able to communicate with a conveyance device that transports the shredded grains that have been sorted in the sorting section, and the grains that have been dehulled in the shedding section. To provide a hulling device, which is equipped with a grain feeding passage for feeding rice (mixed rice), and the grains sent through the grain feeding passage can be switched and supplied to a sorting section side and a rice sorting machine side. It is something.

Next, embodiments will be described in detail with reference to the drawings.

The rice sorter c consists of a cylindrical rotary sieve suspended horizontally downward to the right, and the right end thereof is connected to a rotary wing type grain lifting machine 19, which is connected to the rice sorting machine c. It is connected to a fine grain extraction chute 20 which serves as a fine grain extraction section.
21 is small rice (waste rice) suspended horizontally below the rice sorting machine c.
21a is a receiving gutter for the conveying helix, and 22 is a guide plate.

Next, how to use the hulling device A configured as described above will be explained.

() De-hulling and sorting of paddy grains First, the de-rolls 1, 1 are adjusted to a predetermined appropriate interval, the switching flow path 13 is set in the vertical direction, and the hulling device A is operated to supply paddy. Put the paddy into the hopper 2. Then, the paddy is deprocessed by the derolls 1 and 1, and the chaff is removed while being wind-selected by the winnowers 5 and 18, resulting in a mixed rice of dehulled and unhulled rice, which is sent to the mixed rice receiving trough 41. The mixed rice is then conveyed by the mixed rice removal screw 4 to the lower part of the mixed rice conveyor 6, and is then dumped into the upper supply hopper 8 by the mixed rice conveyor 6.
The mixed rice in the supply hopper 8 is guided from the second passage 12 into the supply helical receiving trough 15a of the sorting section b by the vertical switching passage 13. The mixed rice collected in the receiving trough 15a is sent to the supply port 15b side of the rotary sorting cylinder 14 by a supply helix 15 provided there, and is discharged there. The mixed rice discharged into the rotary sorting tube 14 is separated by the clockwise rotation of the rotary sorting tube 14 (second
(Fig.), while being transferred to the lower part (left side of Fig. 1), only the brown rice is initially picked up by the many small depressions (recesses) 14a... formed on the inner surface of the surrounding wall, and 100% of the paddy falls off. The brown rice is then transferred to the finishing tray 1.
6a, and in the latter half of the transfer,
100% of the brown rice is picked up even with the paddy by the large number of rough depressions (concavities) 14b, and the rotary sorting cylinder 1
At the beginning of the clockwise rotation step 4, mixed rice is thrown into the mixed rice receiving trough 17a, and then brown rice is thrown into the finished rice receiving trough 16a.
Then, the mixed rice is sent to the mixed rice conveyor 6 by the mixed rice screw 17 there, and then sent to the rotary sorting tube 14 again in the same manner as described above, and the brown rice is sent to the finished rice screw 16 there. Conveyor for finished rice 1
The finished rice is sent to the lower part of 0 and placed in the upper supply hopper 8 by the finished rice conveyor 10. The brown rice in the feed hopper 8 is fed into the rice sorter c from the first passage 11, the small rice is dropped through the sieve into the lower receiving trough 21a, and the fine grains are sent to the rotary wing type grain lifting machine. At 19, chute 20 serves as the fine grain removal section of rice sorter c.
It is opened and taken out to the outside.

() Sorting brown rice or wheat First, adjust the distance between the derolls 1 and 1 to prevent derolling, and set the switching flow path 13 in a direction that blocks the second passage 12. With the shaving device A in operation, grains such as brown rice or wheat are loaded into the hopper 2 for supplying paddy. Then,
The grains such as brown rice or wheat are unrolled 1,1
Dust is removed by the winnowers 5 and 18 while the mixed rice passes through the gap and is sent to the mixed rice receiving trough 41 along the guide plate 22. The grains accumulated in the receiving trough 41 are sent to the lower part of the mixed rice conveyor 6 by the mixed rice take-out screw 4, and then are dumped into the upper supply hopper 8 by the conveyor 6. It will be done. The wheat placed in the supply hopper 8 is guided to the first passage 11 by a switching passage 13 that closes the second passage 12, and is supplied into the rice sorter c. This rice sorting machine c
Then, small-diameter grains are stored in the receiving trough 21 below the sieve mesh.
The fine grains are dropped into a rotary wing type grain lifting machine 19
The fine grains are then opened in a chute 20, which is a part for taking out the fine grains, and taken out to the outside.

As explained above, the hulling device according to the present invention has a hulling section (hulling section) that removes paddy grains, and a mixed rice (surichi rice) consisting of shed grains (brown rice grains) and unhulled grains (hull grains). It is equipped with a sorting section for sorting, and a rice sorter for sorting the grain size of the grains sorted from the mixed rice in the sorting section, but the grain feeding passageway for conveying the scraped rice that is rubbed off in the sorting section is not connected to the sorting section. Since the husks can be supplied by switching between the rice sorting machine and the rice sorting machine, by supplying the scraped rice to the sorting section, a series of hulling operations up to sorting by grain size can be carried out. , Also, by supplying the fallen rice to the rice sorting machine,
By widening the spacing between the rolls in the hulling process and inputting grains such as brown rice and wheat from the hopper 2 for supplying paddy in the hulling process, it can be used to sort grain sizes of brown rice, wheat, etc. As a result, the scope of use can be expanded and the operating rate can be increased.
