Description

[Detailed Description of the Invention] In other words, the cylindrical rotary sorting tube and its inner configuration allow for highly accurate sorting, The present invention is provided so that the entire structure can be made small and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the rice hulling sorting device, in which the hulling machine (D) is located above one end of a long earth-type wind sorting section (dl).

, a brown rice conveyor (6), etc. are installed in the gutter, and a suction dust extractor (7) is installed at one end of the wind sorting section (dl).
The suction port (8) is connected to the suction port (9), the opening θO, and the suction port 111), respectively, and is installed so that the sorting air flows above each conveyor and the rice reservoir (12l).

Further, the hulling section (d2) is configured such that a honopar (14) is installed in one of the deweighing chambers of both the dehusking rolls (13), and the lower side thereof is on the side of the mixed rice conveyor (4). shi, wind selection club ω

A rotary grain sorter iE is mounted above the other half of the wind sorting section (d), and both ends are open inside the case (18) of the sorter (F2). A cylindrical rotary sorting tube (A) is installed, but the inner peripheral surface of the sorting tube (A) from one end (A) to the middle is enough to fit brown rice, but not enough to fit paddy. A large number of four parts (1) of the size are formed, and the inner peripheral surface from the middle side to the other end (b) on the paddy discharge side is slightly smaller than the four parts (1) and brown rice can be inserted therein. A large number of small recesses (2) are formed as large as possible, and the recesses (o

At both ends of the sorting tube (A), a total of four rollers flff are brought into contact with each other so as to be supported on the lower left and right sides, respectively, and each roller (1!!) is rotated by a moving shaft (support) ((addition) on both sides. Due to the frictional contact of 11 rollers, the sorting tube IA)

Therefore, when paddy is supplied to the hopper (14) during operation, the grains that have been dehulled by the huller are screened in the wind sorting section (DL), and the mixed rice that falls onto the mixed rice conveyor (4) is mixed. The rice is thrown up into the supply tank @ by the mixed rice thrower (15), and the rice is thrown from the bottom of the nuclear tank to one end of the sorting tube (A) (A).
The mixed rice fed inward is in contact with the inner circumferential surface of the sorting tube (A) rotating in the direction of the arrow (arrow), and the brown rice fits into the recess (1) and is lifted upwards, but the paddy is divided into four parts. In this case, the brown rice that is lifted upward falls from the fourth part (1) and falls into the receiving gutter (B).
The brown rice that fell into the inner spiral conveyor Ia) and was transferred along with the paddy in the direction of the arrow (E) because there was no room to fit it into the four parts (1) was placed on the inner peripheral surface on the side of the small recess (2). As the amount of brown rice decreases, it becomes a yoke that fits into the small recess (2) and is received on the receiving plate in the same manner as described above.
2), the rice grains that are inserted into the paddy conveyor (5) are not able to slide down and are further transferred in the direction of the arrow (E) through the gutter and fall onto the paddy conveyor (5). ) and is once again evacuated.

The brown rice that has fallen onto the spiral conveyor (0) is conveyed as it is in the direction of the arrow (toward), passes through the gutter surface, and is transferred from the falling plate (support) to the brown rice conveyor (6) K, and then to the brown rice thrower-f.
171 and is lifted up and taken out.

In this way, the present invention provides four parts (]) large enough to fully fit brown rice on the inner circumferential surface of the cylindrical rotary sorting cylinder (A) from one end (A) to the middle on the mixed rice supply side.
The inner peripheral surface from the middle side to the other end side (b) on the paddy discharge side is provided with the four parts (1).
A large number of small concave portions (2) are formed which are slightly smaller and are large enough to fit brown rice, and the Tatsumibetsu tube (A,)
A spiral conveyor (c) is mounted above the inside of the brown rice receiving trough (B) built inside the tank, and the stomach tube fA) and the spiral conveyor [a] are placed on the hulling machine (D) side. Because it is connected, brown rice can be separated and sorted from mixed rice by fitting it into the recess (11) and the small recess (2), and a small amount of brown rice is surely inserted into the small recess (2) on the discharge side. At the same time, it becomes even more difficult for the paddy to engage with each other, and it is possible to ensure good sorting performance. It has the advantage of being able to sort well, and also to be able to perform good hulling and sorting due to the communication with the huller (D) side, and the overall size can be made small and can be carried out suitably.
