Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a hulling machine equipped with a rotary sorting device that uses the rotation of a sorting cylinder to separate brown rice with small grains by pumping it up higher than large grains of unhulled rice. It is used.

(Prior art) This rice hulling machine replaces the sorting cylinder with one with a hole of different size depending on the size, length, etc. of the rice grains to be shed. Furthermore, if the pot is used for a long time, dust will become clogged in the pot hole and the sorting performance will deteriorate, so it is necessary to clean it regularly.

In such a case, the sorting cylinder is removed from the sorting case, but conventionally, as shown in Japanese Utility Model Application Publication No. 58-108182, the sorting cylinder is removed from the receiving gutter 26 together with the rear plate 11.
and the sorting cylinder 5 are removed, and then the sorting cylinder 5 is removed again.

(Problems to be Solved by the Invention) That is, according to the conventional device, when removing the sorting cylinder 5 from the sorting case for replacement or cleaning, even the receiving gutter 26, which does not need to be removed, is removed together with the rear plate 11. Not only is it difficult to transport the removed items, but it also requires time and effort to remove the sorting cylinder 5 again.

Furthermore, since this sorting device separates brown rice and unhulled rice at the edge of the receiving trough 26, there is a problem in that when the receiving trough 26 vibrates, the sorting performance becomes unstable.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a sorting cylinder 5 which is provided with a large number of potholes 4, 4... on its inner surface and is long from front to back, and this sorting cylinder 5. A sorting case 8, 11, 1 provided after the removing device 2 and covering the
9, 20, and a receiving gutter 26 extending into the sorting cylinder 5 from the front plate 8 of the sorting case close to the shedding device 2, and the rear end of the receiving gutter 26 far from the shedding device 2 has left and right grooves. A protruding support plate 30 is fixed, and the rear plate 11 is attached to the support plate 11 so that when the rear plate 11 on the far side from the scraping device 2 of the sorting case is removed, the sorting cylinder 5 can be pulled out leaving the receiving gutter 26 behind. Board 30
This rotary sorting type rice hulling machine is characterized in that it is removably installed on the outer periphery of the rice hull and on the sorting case.

(Function) Since the present invention is configured as described above, most of the unhulled rice is peeled off by rubbing off the chaff in the husking device 2.
The rice reaches the sorting cylinder 5 as mixed rice made of brown rice and some unhulled rice. Then, since the sorting cylinder 5 is rotating, this mixed rice is drawn up through its pot holes 4, 4, etc. However, since the long paddy rice is shallowly inserted into the pot hole 4, it falls at a relatively low position. . On the other hand, with brown rice, the rice husks are peeled off and the rice becomes smaller.
The rice goes deep into the pot hole 4, is lifted up to a high position, and falls from the pot hole 4, where it is caught by the receiving trough 26 and separated from the unhulled rice.

When the variety of unhulled rice to be hulled changes and the sorting cylinder 5 is replaced with one with a different size of pot holes 4, 4..., the inside of the sorting cylinder 5 (especially the pot holes 4, 4...) is cleaned. Then, do the following: That is, the fixation between the rear plate 11, the outer periphery of the support plate 30, and the sorting case is removed, and the rear plate 11 is removed. Then,
The rear side of the sorting case is opened, and the sorting cylinder 5 is later pulled out independently from this opened large hole.

Note that the receiving gutter 26 is unstable because it lies for a long time inside the sorting cylinder 5, and may vibrate with the rotation of the sorting cylinder 5, making the sorting unstable. In addition, the rear side is firmly fixed to the rear plate 11 by the outer periphery of the support plate 30, so there is little vibration.

(Effect) As described above, according to the present invention, the sorting cylinder 5
Leave the receiving gutter 26 inside the sorting case,
Since it is pulled out from the sorting case alone, compared to the conventional case in which the sorting case and the receiving gutter 26 are removed together with the rear plate 11, the amount of material to be removed is significantly lighter and the work is easier. Further, in the conventional type, the sorting cylinder 5 had to be removed again after being removed from the sorting case, making it extremely troublesome to remove the sorting cylinder 5. However, according to the present invention, it is only necessary to remove the rear plate 11. Since the sorting cylinder 5 is taken out, the trouble is eliminated.

Furthermore, the receiving gutter 26 is arranged in the pot hole 4 in the sorting cylinder 5.
The upper edge of the brown rice pumped up by 4 has a delicate effect of separating it from the unhulled rice, but the large supporting plate 3
By fixing the outer periphery of 0 to the rear plate 11, the receiving gutter 26 is firmly supported, and has the feature of exhibiting stable sorting performance with little vibration during use.
