Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is directed to a rotary sorting device for pumping and separating small grains of brown rice in jar holes 4, 4 ... It is used for the equipped huller.

(Prior Art) In this hulling machine, the sorting cylinder 5 is replaced with one in which the size of the jar holes 4, 4, ... differs depending on the size of rice grains to be removed and the length of the rice grain. Also, if used for a long time, the potholes 4, 4, ... Will be clogged with dust and the sorting performance will deteriorate, so it is necessary to clean this regularly.

In such a case, the sorting cylinder 5 is removed from the sorting case. Conventionally, as shown in Japanese Utility Model Laid-Open No. 58-108182, the back gutter 26 and the sorting cylinder 5 are removed together with the rear plate 11. After that, the selection cylinder 5 was removed again.

(Problems to be Solved by the Invention) That is, according to the conventional device, when the sorting cylinder 5 is removed from the sorting case for replacement or cleaning, it is removed together with the rear plate 11 to the gutter 26 that does not need to be removed. In addition to the heavy transportation of the removed items, it took time to remove the selection cylinder 5 again.

According to the present invention, this is improved so that only the selection cylinder 5 is extracted alone from the selection case in a state where the receiving gutter provided inside the selection cylinder 5 along the longitudinal direction is left in the selection case. At the same time, it is intended to facilitate the separation from the transmission.

(Means for Solving Problems) In order to achieve the above object, the present invention has a large number of jar holes 4, 4, ... Sorting cylinder 5 and a sorting case 8, 11, 19, which covers the sorting cylinder 5 and is provided behind the removing device 2.
20 and the front end of the sorting case is attached to the front plate 8 on the side close to the removing device 2 and the rear part thereof is the sorting cylinder 5
In the sorting case, there is provided a receiving trough 26 that extends backward in the longitudinal direction and has a helix 25 at the bottom, and four drive rollers 7, 7, ... That support the front and rear ends of the sorting cylinder 5 from below. On the rear plate 11 on the side far from the removing device 2, the gutter 26, the spiral 25
The support plate 30 attached to the rear end of the rear plate 11 is detachably attached, and the rear plate 11 is attached to the sorting case and the gutter 2
6, by removing from the support plate 30 at the rear end of the spiral 25, while the front end of the gutter 26, the spiral 25 remains attached to the front plate 8 and the support plate 30 at the rear end of the spout 26, the spiral 25. In the state of being attached, only the selection cylinder 5 is configured to be removable so that it can be pulled out rearward, and a pair of flanges 6, 6 are fixed to the front and rear outer peripheral portions of the selection cylinder 5.
A rotary selection type huller characterized in that front and rear drive rollers 7, 7 are arranged so as to sandwich a large diameter portion provided inside the pair of flanges 6, 6 facing each other. And

(Operation) Since the present invention is configured as described above, most of the paddy rice is scraped off by the removing device 2 to form the mixed rice made of brown rice and a little paddy rice in the selection cylinder 5. Reach Then, since the sorting cylinder 5 is rotating, its jar holes 4, 4 ...
This mixed rice is pumped up, but long paddy rice falls into the jar hole 4 shallowly, so it falls at a relatively low position.
On the other hand, since brown rice is peeled off and becomes small, brown rice is deeply inserted into the jar hole 4, lifted up to a high position and dropped from the jar hole 4, received by the gutter 26 and separated from the previous rice grain.

The varieties of paddy rice to be removed have changed and the selection cylinder 5 has been jars 4, 4 ……
When replacing with a different size, or when cleaning the inside of the sorting cylinder 5 (particularly the jar holes 4, 4, ...), do the following. That is, the rear plate 11 and the sorting case are unfixed, and the rear part of the trough 26 is also unfixed. Then, the rear side of the sorting case is opened, and the front end portion of the gutter 26 located in the sorting cylinder 5 is supported only by the front plate 8 of the sorting case, and the rear side of the sorting case is opened. The sorting cylinder 5 is independently pulled out rearward from the opened large hole.

At this time, the rear end of the sorting cylinder 5 is lifted to remove the rear side flange 6 from the rear side drive rollers 7,7, and then this is pulled back. Then, since the front flange 6 does not have a portion with a large diameter in front of the front drive rollers 7,7, the front flange 6 slips off smoothly and is easily taken out.

During operation, the front and rear drive rollers 7,7 are arranged so as to sandwich the large diameter portion of the front and rear flanges 6,6,
The sorting cylinder 5 is prevented from moving back and forth, and stable sorting performance is exhibited.

(Effect) As described above, according to the present invention, the sorting cylinder 5 is pulled out from the sorting case by itself while leaving the gutter 26 and the spiral 25 in the sorting cylinder 5 in the sorting case. Compared to the conventional one in which the gutter 26 and the gutter 26 are removed at the same time, the one to be removed is significantly lighter and the work is easier. Also, in the conventional case, it is necessary to remove the sorting cylinder 5 again after removing it from the sorting case once,
Removal of the selection cylinder 5 was extremely troublesome, but according to the present invention, since the selection cylinder 5 can be removed only by removing the rear plate 11, the trouble is eliminated.

In particular, since the sorting cylinder 5 is arranged such that the front and rear drive rollers 7, 7 sandwich the large-diameter portion inside the pair of flanges 6, 6 fixed at both ends thereof, the sorting cylinder 5 can be operated during operation. In addition to exhibiting stable sorting performance without moving back and forth, when removing this sorting cylinder 5, lift the rear side and remove the rear flange 6 from the rear drive rollers 7,7. The pulling operation of the sorting cylinder 5 is extremely simple because the flange 6 at the far front position slides off from the front drive rollers 7, 7 and is disengaged from each other by simply pulling the pulling cylinder 5 afterward.
