Description

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

In conventionally known rice hulling devices, a wind sorting section is formed below the hulling section, and the hulled material is dropped into the wind sorting section at the lower blade position for air sorting.

This publicly known 4111-built one has a hull size of 81 (and I9t+8
Because they are placed in a position below the top, they inevitably have the disadvantage of being tall.

Therefore, the present applicant has already proposed the idea of arranging the hulling section and the Ut sorting section in a horizontal positional relationship instead of vertically.

However, the lateral movement of the wind-selecting chain in the prior art has a blowing section for blowing air, a hulling section, and a wind-selecting section for sucking and discharging the wind sent from the blowing section. The rice husks were sorted through the joint work of a - and a suction blower.

The present invention is a further improvement of the prior art described above, in which the hulling device is constructed in a small size by using only a hulling section and a suction air sorting section without using a blowing section.

Therefore, the present invention does not provide an air blowing section, but forms a hulling section by a hulling section and a suction wind sorting section, and the suction wind selection section is placed not at the bottom of the hulling section but at a sideways position of the hulling section. A suction blower is installed in the suction wind sorting section, and the hulling device is configured to separate the rice grains with wind by the suction blowers, and the paddy hulling device has a suction air passage of the suction blower formed below the hulling section. It has the configuration of a sliding device.

To explain the example diagram, ■ is a vertical tensioning elevator,
Guide rolls 2.3 are attached to the upper and lower sides, and a bucket belt 4 is hooked to and rotated by the guide rolls 2.3. A tensioning opening 5 is formed at the lower end of the tensioning lift al. There is a discharge port 6 on the side of the upper end of the tensioning elevator l.
is opened, and a fixed hopper 7 is placed outside the discharge port 6. The lower end of the fixed hopper 7 is fixed to the upper surface of an outer case 9 of a hulling section 8 provided at a lower position thereof.

Overflow port 10 in the middle part of the fixed hopper 7
11 is an on-off valve.

A fixed rotating shaft 12 is arranged inside the hulling section 8,
A fixed rotary hulling roll 13 is mounted on the fixed rotary shaft 12. A movable rotation shaft 1 is located below the front side of the fixed rotation shaft 12.

16 is a feed roll, and a sink plate 17 is provided below gB of the feed roll 16. The base of a guide plate 18 made of synthetic resin is fixed to the lower end of the sink plate 17, the tip of the guide plate 18 faces between the hulling rolls 13 and 15, and the tip of the guide plate 18 faces between the movable and rotating hulling rolls. 15 in elastic contact with the upper surface.

A swing type spreading device 19 is provided at the lower part of the discharge side of the hulling rolls 13, 15, and spreads the hulled material discharged from between the hulling rolls 1315 in the width direction.

Reference numeral 20 denotes a suction wind selection section provided on the discharge side of the hulling roll 13.15, and a suction blower 21 is installed on the side of the suction wind selection section 20.
or may be provided. An eccentric ring 23 is attached to the rotating shaft 22 of the suction blower 21, a rod 24 is fixed to the eccentric ring 23, and the swing type diffusion device 19 is fixed to the other end of the rod 24. The suction hole 25 of the suction floor 21 is provided below the outer case 9 at a position farther from the hulling roll 13.15 when viewed from the suction blower 21.

Then, the sorting air sucked through the suction holes 25 passes under the movable rotary hulling roll 15 and is sucked into the vertical cyclone chamber 26.
A suction air passage 37 is formed below the dynamic diffusion device 19.

FIG. 2 shows an embodiment in which the outer case 9 is formed by overlapping the upper part of the underframe 38, so that the suction air passage 37 is formed inside the underframe 38. A swing type sorting device 28 is provided below the swing type diffusion device 19. A distribution supply gutter 29 is provided above the swing type sorting device 28. A large number of feed protrusions 30 are provided on the bottom surface of the distribution supply gutter 29. The sorting plate 31 has a structure in which multiple stages are stacked, and is attached to the upper end of a swinging support 33 whose lower end is attached to a shaft 32 so as to be horizontally swingable in the front-rear direction. 34 is a sorting protrusion formed on the upper surface of the sorting plate 31.

A large foreign matter removal plate 35 is provided in the paddy rice discharge gutter of the multistage sorting plate 31, and a small foreign material removal plate is provided in the brown rice discharge gutter.

In the figure, 36 is a port for returning unhulled rice.

Next, we will discuss the effect.

When the raw material, unhulled rice, is supplied to the loading port 5, it is raised inside the loading elevator 1 by the noheket belt 4, and is stored in the fixed hopper 7 from the outlet 6, and when the storage amount exceeds, Flows out from overflow port 10 and returns unhulled rice]
Returned to ko36.

When the on-off valve 11 is opened, the grain stored in the fixed hopper 7 is fed out by the feeding roll 16 and transferred to the sink plate 17.
The grain passes through the grain, advances onto the guide plate 18, is supplied between the hulling rolls 13 and 15 without overflowing downward, is hulled, and flows into the swinging type spreading device 19.

Therefore, an eccentric wheel 2 is attached to the rotating shaft 22 of the suction blower 21.
When the eccentric wheel 23 rotates, the mechanical spreading device 19 vibrates downward through the opening 24 whose upper end is fixed to the eccentric wheel 23. It falls in a state where it is uniformly dispersed in the width direction and is supplied into the distribution supply gutter 29.

During this period, when the suction blower 5-21 of the suction air selection unit 20 rotates, some of the air passes through the suction hole 25 → suction air path 37 and is sucked, and the hulled rice particles falling from the swinging diffuser 19 are sucked. The light-weight rice husks are efficiently sucked through the space and removed from the system via the exhaust pipe 27 by the suction blower 21.

Distribution supply! The mixed rice that fell on 1J29 is distributed into 1 distribution feed gutter 2.
Since the paper 9 moves back and forth together with the sorting plate 31, it is fed by the feeding protrusion 30 on the bottom wall and distributed and supplied to the sorting plates 31 of each stage.

Paddy rice and brown rice supplied on the sorting plate 31 are sorted by the sorting protrusion 34
The brown rice is sorted by the action of , and is taken out to the brown rice discharge gutter and discharged onto the small foreign matter removal plate.

Further, straw waste and the like are removed from the unhulled rice by a large foreign matter removal plate 35, and only the unhulled rice flows into the unhulled rice returning port 36, where it joins with the unhulled rice from the loading port 5 and is reprocessed.

As explained at the beginning, in conventionally known rice hulling devices, the hulling section is located at the L section and the winnowing section is located at the bottom. As a result, he became taller. Therefore, the present applicant proposed that a suction windscreen section be provided next to the hulling section. However, the prior art was composed of a blowing section, a hulling section, and a suction wind sorting section. However, it was discovered that the air blowing section could be omitted by particularly devising the air passage of the suction blower and increasing the capacity of the suction blower, so the present invention provides a rice hulling device that does not include the blowing section. , without providing an air blowing part, the hulling part is formed by the hulling part 8 and the suction wind sorting part 20, and the suction wind sorting part 20 is placed not at the lower part of the hulling part 8 but at a lateral position of the hulling part 8. A suction blower 21 is provided in the suction wind sorting section 20, and the hulling device is configured to perform air sorting by - suction soloers 21, and a suction air path 37 of the suction blower 21 is provided below the hulling section 8. Since the structure of the rice hulling device is formed, the ventilation section can be easily omitted.
