Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sorting device for sorting brown rice from a mixed rice of unframed paddy and brown rice in a hulling section.

[Conventional technology]

Most of the sorting devices used in rice hulling machines were of the swing type, but this swing type sorting device is large and has disadvantages such as high vibration and noise, so it is not considered as a prior art. Japanese Patent Application Laid-Open No. 49-24745 discloses that j5N of brown rice from mixed rice after hulling is placed in a horizontal rotary sorting cylinder having a large number of four recesses formed on the inner peripheral surface, and the axial force of the sorting cylinder is 1ii. It is proposed to use a rotary sorting device equipped with a brown rice receiving trough with a cloudy extension.

In this prior art, the mixed rice supplied to the supply side at one end of the sorting cylinder is scraped up to a height by the rotation of the sorting cylinder, and then flows repeatedly to fall to the bottom.
During the process of forming a fluidized bed and moving to the discharge side of α11), the brown rice of the mixed rice is held up to a relatively high position while being stuck in the recess, and then falls down, leaving the mixed rice. Taking advantage of the fact that the paddy falls from a lower position than the brown rice, the brown rice falling from a higher position is received by the brown rice catcher and taken out, while the discharged paddy discharged from the other end of the sorting tube is removed. It is transferred to the sliding section and subjected to the frame removal operation again, but when sorting in the sorting cylinder, even if the grains are the same, depending on the grain, the degree to which it fits into the recesses or the degree to which it slides against the recesses may vary depending on the size and size. Because it varies slightly depending on the moisture content,
Some brown rice falls from a relatively low position, while some paddy can be lifted to a relatively high position.

[Problem that the invention seeks to solve]

In this case, the prior art only provides one brown rice receiving gutter in the sorting cylinder, and the brown rice that does not enter this brown rice receiving gutter is mixed into the discharged paddy that is transferred to the hulling section. However, when exchanging rice, the amount of discharged paddy increases and the proportion of brown rice in this discharged paddy increases, which increases the load on the hulling section and reduces the amount of hulling. A lot of brown rice is damaged during sliding, and some of the paddy that gets stuck in the four parts and lifted to a relatively high position during the flow enters the brown rice receiving trough, reducing the accuracy of sorting brown rice. there were.

The present invention solves this problem by providing three receiving troughs within the sorting cylinder.

[Means for solving problems]

For this reason, the present invention horizontally installs a rotary sorting tube with a number of concave portions formed on its inner circumferential surface, and places one end of the sorting tube on the supply side of the mixed rice of paddy and brown rice from the hulling section, and the other side. A hulling machine comprising: each end of the hulling section being configured on the side of the hulling section for discharging paddy to the paddy supply section, and a brown rice receiving trough extending in the axial direction of the sorting tube over its entire length in the sorting tube. In the rotary sorting device, a rough sorting brown rice receiving gutter for receiving brown rice that does not enter the brown rice receiving gutter is provided in the sorting cylinder, and the brown rice receiving gutter is arranged so as to extend over the entire length in the axial direction of the sorting cylinder. The mixed rice sowing side C in the sorting cylinder is arranged in parallel with the gutter, and inside the sorting cylinder, the above-mentioned rice is placed in the latter half of the axial length near the discharge side. A mixed rice receiving trough for receiving the unpolished rice in the paddy discharged from the sorting cylinder is arranged in parallel with the rough sorting brown rice receiving trough on the mixed rice sowing side of the sorting cylinder.

[Action/effect of the invention]

In such a configuration, while the mixed rice supplied to the supply side of the sorting cylinder flows toward the discharge side as the sorting cylinder rotates, some of the brown rice in the mixed rice enters the concave portion. Items that get stuck, are lifted up to a high position, and then fall enter the brown rice receiving trough, and therefore most of the brown rice is in the brown rice receiving trough and is taken out of the machine from the brown rice receiving trough.

On the other hand, some of the brown rice in the mixed rice that is lifted to a lower position than the above and falls, and a very small portion of the brown rice that is lifted to a relatively high position behind the paddy in the mixed rice, are It enters the coarsely selected brown rice receiving channel which is located on the side of the mixed rice scooping up side of the sorting cylinder rather than the receiving channel. Therefore, brown rice with a high proportion of brown rice containing some paddy enters the coarsely selected brown rice receiving channel. The number of paddy that enters the gutter can be reduced.

In this way, as the brown rice flows through the sorting cylinder and is transferred to the discharge side, it enters the brown rice receiving trough, and the coarsely selected brown rice with a high ratio of brown rice containing some paddy enters the coarsely selected brown rice receiving trough. As a result, the proportion of paddy in the mixed rice in the sorting barrel increases rapidly as it approaches the discharge section.

However, in the latter half of the sorting cylinder closer to the discharge side, a mixed rice receiving gutter is provided at a position on the mixed rice scraping side in the sorting cylinder compared to the coarsely selected brown rice receiving gutter, so that the sorting cylinder can be discharged. The brown rice contained in the paddy being discharged from the side can be sorted and separated into the mixed rice receiving trough.

Therefore, according to the present invention, part of the brown rice in the mixed rice is removed during fluid transfer in the sorting cylinder so that it enters the rough sorting brown rice receiving trough, and in the latter half of the sorting cylinder near the discharge side. Coupled with the fact that the remaining brown rice that cannot enter the rough sorting brown rice receiving trough is removed to enter the mixed rice receiving trough, it is included in the discharged paddy that is returned from the discharge side of the sorting tube to the hulling section. Since brown rice can be almost completely eliminated, there is less damage to the brown rice when re-hulling the discharged paddy, increasing the yield. In addition, the number of paddy that enters the brown rice receiving gutter is reduced compared to the presence of a coarse brown rice receiving gutter that is installed parallel to the brown rice receiving gutter along the entire length of the sorting body, so it is easier to sort brown rice. It has the effect of improving accuracy.

〔Example〕

The present invention will be explained below with reference to drawings of embodiments.
The figure shows a vertical sectional front view of the entire rice huller, and the rice huller 1aA
The whole is constructed by placing a hulling section C on one side of the second side of a wind sorting device B, which is a rectangular box, and placing a two-stage sorting device side by side with this.

The hulling section C consists of a paddy supply bomber 10, a pair of de-frame rolls 9, etc., while the wind selection device B consists of the hulling section C.

The conveyor 1 includes a brown rice conveyor 2 at the bottom of the brown rice sorting room 4, and a mixed rice thrower 7 communicating with the mixed rice conveyor 1 and a brown rice thrower communicating with the brown rice conveyor 2 on the side thereof. -8 is installed upright, and furthermore, a suction dust exhaust fan 5 is provided at one end of the wind selection device B, and an atmospheric air intake port 6 is provided at the other end.

The two-stage sorting device separates the mixed rice that has been de-framed and wind-sorted by the hulling section C and the wind sorting device B into brown rice and paddy, and in this two-stage sorting device, Symbols ``■'' and ``■'' indicate primary and secondary sorting tubes with both ends open and having a large number of concave portions 11 formed on the inner circumferential surface. II is arranged in a box-shaped case 12 in two lower stages, and a plurality of rollers 13 are used to connect the supply side This discharge side Y is supported by the hulling part C.
Both sorting cylinders 1 II are provided adjacent to the
The motor M in the wind selection device B rotates it in the right direction as shown by the arrow in FIG.

Inside the upper primary sorting tube ■, a brown rice receiving trough 14 with an open-top spiral conveyor 15 is arranged so as to extend over the entire length in the axial direction of the sorting tube ■. 111 selected brown rice receiving channels 16 with spiral conveyor 17
is arranged so as to extend over the entire length in the axial direction of the sorting tube I at a position on the left side of the brown rice receiving trough 14, that is, at a position on the mixed rice scraping up side in the sorting tube I.
Inside the next sorting tube I, there is a mixed rice receiving gutter 18 that also serves as a mixed rice transfer gutter in the spiral conveyor 19, and a mixed rice receiving gutter 18 is located at the left side of the rough selection brown rice receiving gutter 1G, that is, for sowing mixed rice in the sorting tube I. It is arranged so as to extend in the axial direction of the sorting f'li'il over its entire length in the raised side position.

In this mixed rice receiving trough 18, the first half of the axial length of the sorting tube ■, which is closer to the supply side
Therefore, in the axial direction of the sorting cylinder I, only the latter half of an appropriate length from the part closer to the discharge side to the discharge side Y is opened 21, and brown rice and paddy enter only through this opening 21. The mixed rice receiving trough 18 transports the mixed rice from the discharge side Y to the supply side X, and drops the mixed rice into the primary sorting cylinder I from the outlet 18' at the bottom of the terminal. is configured to do so.

Further, the discharge side Y in the primary sorting ff11 extends to the paddy supply popper 10 in the hulling section C so that the discharged paddy from the discharge side Y of the sorting tube (3) enters the paddy supply popper 10.

There is also an open-top type inside the two-person selection section below! ! A brown rice receiving trough 22 with an I-turn conveyor 22' is arranged so as to extend over the entire length of the sorting tube H in the axial direction of the sorting tube H.

In the figure, reference numeral 23 indicates the brown rice receiving trough 14 in the primary sorting section I.
A communicating gutter that allows the brown rice received in the secondary sorting tube II to flow into the brown rice receiving gutter 22; 25 is a communication path for flowing into the supply side X in the human sorting section (2); 25 is a circulation path that communicates the ()1 output side Y of the secondary sorting cylinder (2) with the mixed rice thrower 7; 26 is a two-person sorting section. ■The brown rice in the brown rice receiving trough 22 is transferred to the brown rice sorting chamber 4 in the wind sorting device B by the flow plate 27.
This is the path to lead to the second point.

Furthermore, the reference numeral 28 in the figure is a supply tank for mixed rice, and the paddy f, J
The lower part of the supply tank 28 is attached to the side wall 12' on the upper side of section C, that is, the discharge side Y, and the lower part of the supply tank 28 is connected to the starting end of the mixed rice and wheat II 18, which also serves as a mixed rice transfer gutter that goes into the first reformation section (2). The mixed rice thrower 7 is in communication with the supply tank 28.
The tip 7' of is open.

In addition, the brown rice receiving gutter 14, the rough selection brown rice receiving gutter 16, and the brown rice receiving gutter 22 are provided with control valves 29, 30, and 31, respectively.

During the hulling operation, the paddy supplied into the paddy supply popper 10 in the hulling section C is sequentially unframed by a pair of unframed rolls 9, and then wind sorted by a wind sorting device B. The mixed rice is fed into the supply tank 28 by the rice thrower 7. After the mixed rice in the supply tank 28 is transferred to the supply side
It is sequentially supplied to the supply side X within.

The mixed rice thus supplied to the supply side X in the primary sorting tube I is scraped up to a height created by the rotation of the one-person sorting tube I, and then falls to the bottom, repeating the flow until it reaches the second sorting tube I.
As shown in the figure, the brown rice is transferred toward the discharge side Y while forming a fluidized bed S. In the middle of this fluidized transfer, the brown rice in the fallen rice is stuck in the four parts 13 and placed at a relatively high position. After being lifted up to a certain level, the brown rice falls from the recess 13 and enters the brown rice receiving channel 14, while the coarsely selected brown rice receiving channel 16 contains
Roughly selected brown rice with a high proportion of brown rice containing some paddy is included.

The coarsely selected brown rice that has entered the coarsely selected brown rice receiving channel 16 is
Through H4, it flows down to the supply side X in the secondary sorting tube ■, which is the re-sorting point, and while flowing inside this sorting tube ■, it is transferred to the discharge side Y.Only brown rice flows into the brown rice receiving trough 22. be selected to enter.

In addition, the brown rice that has entered the brown rice receiving trough 14 in the primary sorting tube 1 flows into the brown rice receiving trough 22 in the secondary weekly section H via the communication path 23, and is transferred to the brown rice receiving trough 22 in the two-person sorting section 2. Along with the brown rice that enters the gutter 22, it flows down from the passage 26 onto the drop board 27, is sorted in the brown rice sorting chamber 4, and then taken out of the machine from the brown rice thrower 8.

The mixed rice that moves toward the discharge side Y while flowing in the separate cylinder 1 has a higher proportion of paddy as it moves toward the discharge side Y. The brown rice containing paddy is removed so that it enters the mixed rice receiving trough 18, which has only an opening 21, and becomes almost only paddy.Then, it is returned to the paddy supplying bomber 10 in the hulling section C, and is deframed again. While this operation is being carried out, the brown rice containing paddy that has entered the mixed rice receiving trough 18 through its opening 21 joins the mixed rice supplied to the primary sorting tube 1 and is re-sorted.

On the other hand, 1J1 of mixed rice of paddy and unpolished rice is also discharged from the discharge side Y end of the secondary sorting cylinder 6, and this discharged mixed rice is passed through the circulation path 25.
The rice flows down through the mixed rice thrower 7 and is supplied again to tank 2B.
II will be sent within.
