Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hulled rice sorting device for a hulled rice sorting machine which removes rice husks, dust and the like from the brown rice sorted by a hulled rice sorting machine and taken out of the machine.

[0002]

2. Description of the Related Art A hulling section and a falling rice wind sorting section are arranged at the front of the machine body, and a mixed rice sorting section and a mixed rice sorting section composed of a swing sorting device are arranged at the rear section of the machine body. A grain hull sorting machine is arranged by arranging a brown rice grain lifting machine that takes out the selected brown rice, and the dust such as rice husks sucked from the brown rice outlet at the upper part of the brown rice graining machine is composed of a flexible material. It is sent to the suction air duct in the mixed rice sorting section at the rear of the machine with a dust suction pipe, and then sent to the suction fan at the front of the machine through the dust suction air channel in the slid-down rice wind selection section at the front of the machine, and the suction fan Some are discharged from the machine by merging with the dust from the scraped-off rice air selection section.

[0003]

In such a conventional device, dust such as rice husks sucked from the brown rice lifting machine at the rear of the machine body is formed in the mixed rice sorting section at the rear of the machine body. Since it is sent to the suction fan in the front of the machine through the dust path in the front of the machine and the dust collecting air path in the front of the machine, There is no problem with the type in which the rice section and the mixed rice sorting section are integrally configured, but the hulling section, the falling rice wind sorting section and the mixed rice sorting section are divided into a plurality of blocks. In the type that assembles these block constituent members to form a hulled rice sorting machine, the dust suction air passage of the mixed rice sorting portion and the dust suction of the sliding rice wind sorting portion which are configured separately and independently. There is a drawback in that the connection with the air passage requires special consideration and the structure becomes complicated.

Therefore, according to the present invention, the dust suction air passages are provided on the machine base, which is arranged at the bottom of the machine body, and on which the hulling section, the falling rice wind selecting section and the mixed rice selecting section are mounted, the paddy is provided. Although the slide sorting machine is composed of multiple blocks for easy transportation, it is easy to supply dust such as rice husks sucked from the brown rice outlet of the brown rice lifting machine to the suction fan at the front of the machine. In order to overcome the drawbacks of the conventional device.

[0005]

The present invention takes the following technical means in order to solve the problems of the prior art. That is, according to the present invention, the paddy hull A and the falling rice wind sorting unit B are mounted on the front of the machine base 36, and the mixed rice sorting unit C is mounted on the rear of the machine base 36. Is a hulled rice sorting machine provided with a brown rice fried machine 3 for taking out the brown rice sorted by the mixed rice sorting unit C, and a dust suction passage 34 provided vertically along the brown rice fried machine 3 The upper end is communicated with a dust collection chamber 40 that absorbs dust from the brown rice extraction port 3a in the upper part of the brown rice fried machine 3, and the lower end of the dust passage 34 is integrally incorporated in a machine base 36 extending in the front-back direction of the machine body.

Then, the slid-down rice selected by the slid-down rice receiving trough 9 is conveyed to one side by the slide-down rice spiral 13, flows into the lower part of the mixed-rice fried machine 2, is fried, and is mixed-rice hopper. 14 and then to the swing selection plates 16, 16, ... Via the distribution gutter 17 and the distribution case 18.

In this way, the swing selection plates 16, 16,
The mixed rice supplied to ... is sorted by the size of the grain shape, the size of specific gravity, the difference in friction resistance, etc. by the reciprocating swing of the swing arm (not shown) in the horizontal direction, and the horizontal shake The brown rice that is distributed unevenly in the brown rice distribution basin on the upper side is separated by the brown rice partition plate 19 and taken out, and the brown rice gutter 21,
It flows into the lower part of the brown rice fried machine 3 through the brown rice flume 22, is fried by the brown rice fried machine 3, and taken out of the machine. Further, the mixed rice distributed unevenly in the mixed rice distribution basin, which is an intermediate portion in the lateral direction of the rocking sorting plates 16, 16, ... Is separated by the brown rice partition plate 19 and the paddy partition plate 20 and taken out, and then mixed. The rice flows out to the small rice sorting / conveying device 29 through the mixed rice receiving gutter 23 and the mixed rice flow path 24, and after the small rice / green rice is removed by the small rice sorting / conveying device 29, flows into the lower part of the mixed rice fried machine 2. Are fried and further fed through the mixed rice hopper 14, the distribution gutter 17, and the distribution case 18 to the rocking sorting plates 16, 16, ... In addition, the unbalanced paddy in the paddy distribution basin on the side of the rocking sorting plates 16, 16, ...
Is separated and taken out, passed through the paddy trough 25, the paddy flow path 26, and the paddy grain elevator 27, and is fried and reduced to the grain hull portion A, and then grained again.

The rice husks are sorted in this way, but the rice husks sucked from the take-out port 3a of the brown rice fried machine 3
The dusts are collected in the brown rice fried case 3b of the brown rice fried machine 3 integrally with the dust suction passage 34 and the joint hose 3.
5, a dust suction air passage 37 integrally provided on a machine stand 36 on which a hulling section A having a plurality of blocks, a falling rice wind selecting section B, and a mixed rice selecting section C are mounted, a joint ho 35,
It is sucked by the suction fan 1 and discharged to the outside of the machine through the communication air passage 38, and is sucked and removed via the dust suction air passage 37 provided in the machine base 36 that extends from the front part to the rear part of the machine body. Therefore, although the block constituent members are placed on the machine base 36 to assemble the grain hull sorting machine,
The configuration of 7 is simplified to eliminate the drawbacks of the conventional device.

[0016]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the rice husks and dust that have been sucked into the dust collection chamber 40 from the take-out port 3a of the brown rice frying machine 3 are fried with the brown rice frying machine. Grain case
The dust suction passage 34 provided integrally with the sheet 3b, and the hulling portion A and the sliding rice wind selecting portion B which are constituted by a plurality of blocks.
The dust is sucked by the suction fan 1 and discharged to the outside of the machine through the dust suction air passage 37 that is integrally provided on the machine stand 36 on which the mixed rice sorting unit C is placed.
