Description

[Detailed Description of the Invention] The present invention relates to a No. 1 conveyor device in a rice husking machine.

In other words, in a hulling machine configured with a circulation air passage visible below the derolling machine, the No. 1 conveyor gutter was conventionally installed inside the machine body, but the present invention has installed the No. 1 conveyor gutter inside the machine body. By configuring it so that it is on the outside of the machine, cleaning and maintenance inspection of the No. 1 conveyor gutter can be easily performed from the outside, and it is possible to further improve the No. 1 sorting performance by wind selection.
It is provided that the structure is simple and can be suitably implemented.

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

The figure shows a cross-sectional view of the huller, in which two de-rolls 1, 1 are mounted on a shaft in a dechamber 8 below the upper supply hopper 7, and a shell plate 9, A downward drop port 3 is formed in the lower part of the drop port 9, and the bottom of the drop port 3 is seen into a circulation air path 2. The circulation air path 2 is connected to the suction port 11 and the exhaust port 12 of the suction device 10. It has a closed circuit structure that communicates, and a sorting shelf 4 is provided diagonally below the part of the air passage 2 facing downward from the drop opening 3.
A No. 2 conveyor gutter 14 on which the spiral conveyor 13 is mounted is installed below the upper end side, and a sorting air passage 1 communicating with the circulation air passage 2 is installed above the gutter 14.
A conveyor gutter 17 having a conveyor 16 for paddy hulls mounted thereon is installed below the circulating air passage 2 on the side communicating with the suction port 11 of the suction machine 10.

In addition, a No. 1 conveyor gutter 6 is installed below the lower end of the sorting shelf 4 so as to straddle the diagonal circulation air passage 2 and be positioned outside the machine body. The spiral conveyor 5 is mounted on an axis, and the side part of the first conveyor gutter 6 on the lower side of the spiral conveyor 5 is pivotally connected by a hinge 18, and the extending part 19 on the other side and the upper support part 20 are connected and fixed by bolts and nuts 21, and installed so that the part of the first conveyor gutter 6 can be opened downward by removing the bolts and nuts 21.

Therefore, during work, the air discharged from the exhaust port 12 of the suction device 10 flows through the circulation air path 2 and the sorting air path 15 as shown by the solid arrows, and is sucked into the suction port 11. It is in a state where it circulates inside the aircraft.

The grains etc. removed by the two removal rolls 1, 1 fall from the drop opening 3 into the air path 2 as shown by the dotted arrow and are screened by the wind, and then flow down the sorting shelf 4 from the lower end A as shown by the dotted arrow. The brown rice falling to the top is further sorted by the wind in the air channel 2, and then transferred to the No. 1 conveyor gutter 6.
The second product, which is transported by the spiral conveyor 5 and sent up by the wind on the sorting shelf 4, falls into the second conveyor gutter 14 and is transported by the spiral conveyor 13, as shown by the dotted arrow, and is separated from the paddy by the spiral conveyor 5. The debris is blown by the wind, falls into the conveyor gutter 17 as shown by the dotted arrow, and is conveyed by the conveyor 16.

When cleaning or maintaining the inside of the No. 1 conveyor gutter 6, remove the bolts and nuts 21 from the outside, and rotate the No. 1 conveyor gutter 6 downward about the hinge 18 as shown by the imaginary line. When opened, the inside can be exposed for cleaning or maintenance.

In this way, the present invention is a huller that is configured with a circulating air passage below the derolling, and a sorting shelf is installed obliquely at the bottom of the air passage facing the drop opening below the derolling, and The No. 1 conveyor gutter of the spiral conveyor shaft is installed below the lower end of the sorting shelf so that it straddles the circulation air path and is on the outside of the machine, so cleaning and maintenance of the No. 1 conveyor gutter from the outside is possible. Inspection can be easily carried out, and the first item that falls from the sorting shelf to the first conveyor gutter can be screened again, further improving the first sorting performance, and it has a simple structure. It has the advantage of being suitable for implementation.
