Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is a rotary sorting tube type tube that sorts mixed rice of paddy and brown rice using a rotating sorting tube that has a large number of pot holes on its inner circumferential surface. It can be used for rice hulling machines.

[Prior art]

A sorting case with a rotary sorting tube that rotates around a horizontal axis and has a large number of pot holes on its inner circumferential surface and a phushu section are installed together, and a paddy hopper on the phushus section side is installed in the adjacent part. There is a method in which the porous dust suction member and the porous dust suction member of the mixed rice hopper on the sorting case side are arranged close to each other, and dust is sucked and removed from these porous dust suction members to the sorting air passage below.

[Problems to be Solved by the Invention] However, in this conventional device, the dust suction effect from the dust suction porous member of the paddy hopper on the side of the husking section and the dust suction porous member of the mixed rice hopper on the sorting case side is insufficient. Therefore, this invention enhances the dust suction effect of this part, and also removes dust from the surrounding areas of the rice hopper on the side of the phushulling part of the huller and the mixed rice hopper on the side of the sorting case. The aim is to improve the working environment of the machine.

[Means to resolve the interlayer]

The technical means of the present invention for solving such technical problems is a sorting case 1 which is equipped with a rotary sorting tube 11 that has a large number of pot holes on its inner circumferential surface and rotates around a horizontal axis.
0 and the husking section 1 are arranged in parallel on the wind sorting machine body 24 that wind-sorts the scraped rice from the husking section 1. The dust suction porous member 25 of the mixed rice hopper 9 on the case 10 side is arranged close to the dust suction porous member 25. 4, and is arranged above the dust suction porous member 25 of the reduced rice hopper 23 on the side of the dehulling section 1 and the dust suction porous member 25 of the mixed rice hopper 9 on the sorting case 10 side, and The dust suction fan 28 that sucks the surrounding dust is connected to the dust suction porous member 25 of the reduced rice hopper 23 on the side of the shredding section 1 and the dust suction porous member 25 of the mixed rice hopper 9 on the sorting case 10 side through the upper dust suction path 30.
The structure of the dust suction device for the huller is constructed by connecting the two.

[Function and effect of the invention]

During the hulling and sorting work, the dust suction porous member 25 of the reduced rice hopper 23 on the side of the hulling section 1 and the mixed rice hopper 9 on the side of the rotary sorting cylinder 11 are removed.
J! scattered from the dust suction porous member 25! ! A portion of the dust is removed by taking the lower dust suction path 26 and flowing into the sliding rice wind selection path 4, and a portion of the dust is sucked into the upper dust suction fan 28 through the upper dust suction path 30. The dust is then discharged to the outside of the machine via the dust exhaust pipe 29. In addition, a support tube 27 is connected to the dust suction fan 28.
Dust around the huller is sucked and removed through the holes.
A good working environment can be achieved.
