Then, dust such as bran passing through the brown rice discharge pipe 39 together with the brown rice is sucked into the fan case 46 via the bypass hose 41a and the bypass pipe 41b due to the suction force accompanying the rotation of the fan 26, and together with the rice husks. Hulling machine 2 via the exhaust cylinder 30
1 is discharged to the outside. Therefore, in this embodiment, the collecting means is constituted by the bypass hose 41a and the bypass pipe 41b which constitute the bypass path, and the suction fan 45 as the suction member.

Next, the operation of the huller constructed as described above will be described. In this configuration, when the paddy 23 is removed, the hulling machine 21 is operated,
When the rice 23 is thrown into the rice hopper 22, the rice 23 passes through the rice receiving unit 24 and enters the inside of the drying fan case 25. Then, the paddy 23 is removed by the removal fan 26, and the mixed rice hulls and brown rice are sent to the wind separation unit S through the frying cylinder 31 by the removal action.

Negative pressure is generated in the main body casing 21a by the rotational force of the suction fan 45, and the air flows into the wind separation section S in the main body casing 21a from the opening 21b by the negative pressure. By the air pressure, rice hulls, shiina, and brown rice are each sorted in the wind sorting section S. Then, the rice husks are discharged from the dust discharge tube 30 to the outside of the hulling machine 21 through the suction port 46a of the fan case 46, while the shiina is discharged to the outside of the hulling machine 21 from the shiina discharge pipe 42, and further, brown rice and wind power The rice hulls and shiina that have not been sorted fall onto the sorter 33.

Foreign substances such as relatively large debris and pebbles are left on the uppermost oscillating net 33a.
Is housed in the foreign substance collection box 34 from the front end. Of the rice that has passed through the uppermost swing net 33a, relatively large unpolished rice remains on the second-stage swing net 33b. The unremoved rice is removed through a non-recovered rice recovery hose (not shown).
Is sent to the cooling fan case 25 by the suction force. Then, the unpolished rice is recovered again in the ventilation fan case 25.

Among the rice having passed through the second swinging net 33a, mixed rice (mixed with brown rice and unremoved rice) remains in the third swinging net 33c. This mixed rice is oscillating net 33
After falling into the mixed rice collecting unit 36 from the tip of the mixed rice collecting unit 36, the mixed rice is returned to the wind sorting unit S via the mixed rice discharging pipe (both not shown) by the rotational force of the mixed rice discharging fan, as described above. It is sorted by the wind and falls again into the sorter 33.

The mixed rice that has passed through the third stage swing net 33c falls to the lowest swing net 33d, and the swing net 33d
Is further sorted by On the other hand, the mixed rice that has not passed through the oscillating net 33d is removed from the oscillating net 33d by the mixed rice recovery unit 36.
Together with the above-mentioned rather large mixed rice that has already fallen into the mixed rice recovery unit 36, is returned to the wind separation unit S via a mixed rice discharge pipe (both not shown), and as described above. And fall to the sorter 33. Then, only the completely removed brown rice passes through the oscillating net 33d, falls into the brown rice collecting section 38, and the brown rice discharging fan 4
With the rotation force of 4, the brown rice is discharged from the brown rice outlet 40 through the brown rice discharge pipe 39.

When the brown rice passes through the brown rice discharge pipe 39, dust such as bran adhering to the brown rice rises in the brown rice discharge pipe 39 together with the brown rice, and the box-shaped portion 40 of the brown rice take-out port 40.
When the rotation speed reaches a, the suction fan 45 returns the fan case 25 through the bypass hose 41a and the bypass pipe 41b due to the suction force generated by the rotation of the suction fan 45. Since the dust such as the bran is discharged to the outside from the dust discharge tube 30, it is not discharged from the brown rice take-out port 40.

Next, effects that can be found from the present embodiment will be described below. As described above, the huller 21 according to the present embodiment includes the bypass hose 4 in the box-shaped portion 40 a of the brown rice take-out port 40.
1a and the bypass pipe 42a are connected to prevent dust such as bran from going out of the brown rice outlet 40 together with brown rice. As a result, it is possible to avoid that the environment of the place where the collecting operation of the brown rice is performed is deteriorated by the dust, or that the worker inhales the dust and causes a problem in hygiene.

Since the dust such as bran flowing through the brown rice take-out port 40 is collected by the suction action, the spread of the dust can be prevented unlike the case where dust is sprayed and collected.
The working environment can be reliably improved.

Since the rice husks selected by the suction fan 45 can also be discharged, it is not necessary to provide a suction fan and a rice husk discharge fan. Therefore,
Since the number of members does not increase, it is possible to prevent the configuration of the hulling machine 21 from being complicated, and to prevent the manufacturing cost of the hulling machine 21 from increasing.

After the unpolished rice is sorted by the sorter 33, it is sent to the cracking fan case 25 to be stripped.
The process of further sorting is repeated until the unpolished rice is completely refined. Accordingly, all the rice 23 is unnecessarily taken out of the huller 21 as brown rice.

The present invention may be configured as follows in addition to the above embodiment. -In the said embodiment, by rotating one suction fan 45, the bypass hose 41a and the bypass pipe 4
Although the dust such as bran is sucked from 1b and the chaff can be discharged, a dedicated fan for sucking the dust and a dedicated fan for discharging the chaff may be separately provided. In addition, remove each dedicated fan from fan 26
Provided on the shaft 28, the configuration is not complicated.

One end of the bypass hose 41a is connected in the middle of the brown rice discharge pipe 39. With this configuration, the appearance of the hulling machine 21 can be improved because the bypass hose 41a is not exposed outside the main casing 21a.

Providing a plurality of bypass hoses 41a and connecting each hose 41a to the bypass pipe 41b. With this configuration, dust such as bran can be collected more reliably.

The bypass hose is composed of the bypass hose 41a and the bypass pipe 41b.
It may be constituted by 1a alone or by-pass tube 41b alone.

[0031]

According to the first aspect of the present invention, the dust flowing along with the brown rice on the brown rice discharge path is collected before the brown rice is collected, so that the dust can be prevented from flying. . Therefore, the working environment can be improved, and the sanitary aspect can be improved.

According to the second aspect of the present invention, since dust is collected by suction, the dust can be prevented from spreading, unlike collection by blowing, and the working environment can be reliably improved.

According to the third aspect of the present invention, since the number of members does not increase, it is possible to prevent the configuration from becoming complicated and to prevent the production cost of the huller from increasing.
