Description

[Detailed description of the invention] (a) Industrial application field The present invention provides a huller on one side of a long wind sorting box in the longitudinal direction, and a rotary sorting machine for sorting mixed rice on the other side. The present invention relates to a dust suction device in a rice hulling sorter configured by arranging the following.

(b) Conventional technology Conventionally, in a oscillating sorter or a rice huller sorter combined with a mangoku, the sorting section and the wind sorting chamber are connected to each other, and the dust generated in the sorting section is sucked out. Utility Model Publication No. 54-128980/Japanese Patent Publication No. 55-34197
It is well known from Publication No. 44-22456 and Publication Utility Model Publication No. 44-22456. Furthermore, a device in which the above-mentioned sorting section is a rotary sorting cylinder and the dust inside the rotary sorting cylinder is sucked and removed is disclosed and known in Japanese Patent Laid-Open No. 49-24745.

However, the above-mentioned practical application in combination with a swinging sorter
In the configurations shown in Publication No. 128980 and Japanese Patent Application Laid-open No. 1987-34197, there is no brown rice sorting air path for air sorting the brown rice sorted in the sorting section, and the dust sucked and exhausted from the sorting section is The dust is discharged outside the machine from the suction dust extractor through the waste sorting air passage.

Furthermore, even with the configuration shown in the above-mentioned Japanese Utility Model Application Publication No. 44-22456, which is combined with a mangoku, the dust generated on the mangoku is sucked into the suction dust extractor through the removal air passage. It is now being ejected outside the aircraft.

Therefore, when the dust generated in the sorting section is sucked and exhausted, it merges in the waste material sorting air path, which not only affects the removal effect but also prevents the dust from being removed from the separation section. It's becoming like that.

(c) Problems to be solved by the invention As described above, in the conventional configuration, when the dust generated in the sorting section is sucked and discharged, it merges in the waste material sorting air path and the waste material is separated by air. Since this has the drawback that it not only affects the operation but also obstructs the dust removal from the sorting section, in the case of the present invention, in the case where the sorting section is a rotating sorting cylinder, only one suction dust ejector is used. In addition to effectively performing the wind sorting of the waste from the huller and the brown rice sorted by the rotary sorting cylinder, it is also possible to effectively suck and discharge dust generated in the rotary sorting cylinder. It was invented with the aim of creating a machine that could be used for sanitary work without dust accumulating around the machine, except by removing the dust all at once using a suction dust extractor.

(d) Means for solving the problem Therefore, the present invention provides a huller on one longitudinal side of a long wind sorting box, and a rotary sorting cylinder for sorting mixed rice on the other side. In the hulling sorting machine, the rotating sorting cylinder in the wind sorting box uses a sorting wind to sort out the waste from the hulling machine, and the brown rice sorted by the rotating sorting cylinder. A suction dust ejector is installed to generate a sorting air, and a demolition sorting air path and a brown rice sorting air path formed in the air sorting box are connected to the suction dust ejector separately, and The inside of the rotary sorting cylinder and the suction dust remover are connected through an air passage.

(E) Function With this structure, the waste from the huller is sorted out in the removal air passage, and the dust such as rice husks is sucked into the suction dust extractor and discharged outside the machine, resulting in brown rice and brown rice. The mixed paddy rice is fed into a rotating sorting barrel and is sorted into brown rice and paddy. This sorted brown rice is then wind sorted in a brown rice sorting air passage, and the dust in the brown rice is sucked out by a suction dust extractor and discharged. be.

At this time, the dust generated in the rotary sorting cylinder when the mixed rice fed into the rotary sorting cylinder is subjected to the sorting action is sucked into the suction dust remover from the air passage and discharged to the outside of the machine.

In this way, the suction dust extractor separately suctions dust from rice husks etc. air-selected in the waste sorting air duct, dust from brown rice sorted in the brown rice sorting air duct, and dust generated in the rotating sorting cylinder. It is then ejected out of the machine all at once.

(f) Examples The present invention will be specifically explained below with reference to the drawings of examples.

In addition, a coaxial brown rice conveyor 13 and a paddy conveyor 14 are mounted coaxially in the middle part of the wind sorting box A, and a suction port 15 is formed in the side part in the vicinity thereof.
Cylindrical air passages 2, 2 extend upward from the tops of both air guide covers 12, 12 in front of both suction ports 11, 11 of the suction dust ejector a, and both conveyors 13, 2 are installed from the suction ports 15, The brown rice sorting air path s formed on the top 14 communicates with the suction dust extractor a through the air paths 2, 2, so that the sorting air generated by the suction dust remover a flows, and the mixed rice conveyor 8 and the brown rice conveyor 13 and the end of the paddy conveyor 14 are a mixed rice thrower 16, a brown rice thrower 17, and a paddy thrower 1.
8 are connected to each other, and the upper part of the paddy thrower 18 is connected to the hopper 5 of the huller B.

A case 3 is installed on the wind sorting box A from the vicinity of the huller B to the other side of the suction dust remover A, and a rotary sorting cylinder C is installed inside the case 3. However, the lower parts of the cylindrical air passages 4, 4 arranged in parallel with the air passages 2, 2 are connected to the upper parts of the air guide covers 12, 12 on both sides of the suction dust extractor a, and extend upward. The upper end openings 4a, 4a are exposed on both sides of the rotary sorting cylinder C so as to communicate with the inside of the sealed case 3, and the inside of the rotary sorting cylinder C is suctioned and evacuated by the air passages 4, 4. A wind power regulating valve 20, which is connected to the dust machine a and is operated by a grip 19, is interposed between both air passages 4, 4.

Both ends of the rotary sorting cylinder C are open, and a large number of recesses 21 are formed on the inner circumferential surface of the rotary sorting cylinder C, the size of which is large enough to fit the brown rice.Rotary wheels 22 for supporting and driving are provided on both sides at the bottom of both ends of the rotary sorting cylinder C. . are provided with gate valves 27 and 28 that extend close to the inner circumferential surface of the barrel so that the gate valves 28 are raised, and a tank 29 that communicates with the mixed rice thrower 16 is provided at the upper side of the case 3. The paddy conveyor 14 is equipped with a receiving trough 30 with the lower opening of the tank 29 looking inward on the other side of the rotary sorting cylinder C, and below one side of the rotary sorting cylinder C.
A gutter 31 extends above the brown rice conveyor 13 from the end side of the brown rice receiving gutter 26, and a gutter 32 extends from the end side of the mixed rice receiving gutter 25 onto the mixed rice conveyor 8.
It is constructed by extending the .

As a result, the grains removed by the huller B are sorted by the sorting air that is blown up by the suction dust extractor a and flows in the grain sorting air path r as shown by arrow A. Dust such as rice husks is sucked into the suction dust extractor a from the air passage 1 and discharged outside the machine, and the mixed rice of brown rice and paddy that has fallen into the mixed rice conveyor 8 is thrown up by the mixed rice thrower 16 and sent to the tank 29. The mixed rice in the rotary sorting cylinder C, which rotates as shown by the arrow B, is lifted in the direction of rotation with the brown rice fitted into the recess 21. The paddy and some of the brown rice that fall on the way fall from above the gate valve 27 into the mixed rice receiving trough 25, and the brown rice that is lifted further upwards falls from above the gate valve 28 into the brown rice receiving trough 26, and is rotated. Paddy remains in the sorting cylinder C.

Then, the mixed rice is conveyed by the screw conveyor 23 and falls into the mixed rice conveyor 8 from the gutter 32, and is thrown up by the mixed rice thrower 16 and re-sorted by the rotary sorting cylinder C. Brown rice is transferred to the screw conveyor 24. The paddy is conveyed through the gutter 31 and falls onto the brown rice conveyor 13, and is taken out of the machine by the brown rice thrower 17, and the paddy remaining in the rotary sorting cylinder C falls from the gutter 30 onto the paddy conveyor 14, and is transferred to the paddy thrower 1.

At this time, in the brown rice sorting air path s above both conveyors 13 and 14, the sorting wind flows toward the suction dust extractor a as shown by the arrow C, so that the brown rice and paddy are sorted by the wind. The dust in the unpolished rice and paddy is sucked into the suction dust exhauster a from the air passages 2, 2 and discharged to the outside of the machine.

Further, dust generated in the rotary sorting cylinder C in the case 3 is sucked into the suction dust remover a from both air passages 4, 4, and is discharged to the outside of the machine. At this time, the cross-sectional area of the air passages 4, 4 is adjusted by the wind force control valve 20 to adjust the dust intake.

(g) Effect of the invention As explained above, the present invention provides a long wind selection box A.
In a huller sorting machine configured by disposing a huller on one side in the longitudinal direction and a rotating sorting cylinder for sorting mixed rice on the other side, the rotating sorting cylinder in the wind sorting box is arranged. A suction dust extractor is installed to generate a sorting wind that winds the waste from the crocodile huller, and a sorting wind that winds the brown rice sorted by the rotating sorting barrel. It is configured such that a waste sorting air passage and a brown rice sorting air passage formed in the box are connected to the suction dust extractor separately, and the inside of the rotary sorting cylinder and the suction dust exhauster are connected through the air passage. Therefore, one suction dust extractor can separately suck the dust from the rice husks, etc., which have been air-sorted in the de-object sorting air passage, the dust from the brown rice, which has been sorted by the brown rice sorting air passage, and the dust generated in the rotating sorting cylinder. However, since the dust generated in the rotary sorting cylinder is sucked and exhausted as in the conventional type, it does not flow into the waste material sorting air path, which affects the dust removal effect. Not only does the removal of waste material become better, but the suction and removal of dust generated in the rotary sorting cylinder becomes smooth without being hindered, and the rotary sorting cylinder It is also possible to perform wind selection of selected brown rice.

Moreover, since the suction dust extractor is installed next to the rotating sorting cylinder in the wind sorting box, the air path that communicates the inside of the rotary sorting cylinder and the suction dust extractor is short and effective. It becomes possible to vacuum and discharge dust,
This made it possible to carry out sanitary work without dust accumulating around the machine unless the dust was removed all at once using a suction dust extractor.
