Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a de-stoning device in a de-sorting device.

The mixed grains supplied to the oscillating sorting plate in the de-sorting process are contaminated with weight contaminants such as dirt grains that were not sorted in the wind sorting process, and the contamination of these contaminants causes a decline in the quality of fine grains. This may cause financial damage such as doing so.

The present invention eliminates the above-mentioned grain damage and improves the quality of refined brown rice by providing a stone removal sorting section with a unique structure in the discharge process of sorted brown rice provided on the discharge side of the oscillating sorting plate. The aim is to develop and provide equipment that can reliably mass-produce selected brown rice.

To explain the present invention with reference to an embodiment diagram, FIG. 1 shows that the raw material paddy put into the supply port 2 of the dechambering 1 is hulled between the dechambering rolls 3 and 4 of the dechambering 1, and the removed material is removed. Rice husk air sorting chamber 5 consisting of a sorting air passage
The rice husks are air sorted inside the machine and the rice husks are discharged outside the machine, and the mixed grains of different kinds are supplied from the rice husk air sorting chamber to the swinging sorting plates 7 via the grain lifting machine 6. The grains on the plate surface are sorted by the oscillating sorting action of the sorting plate, which vibrates diagonally up and down.
Brown rice is flowed on the higher side of the sorting plate surface, unhulled rice is flowed on the lower side, mixed grains of paddy and brown rice are flowed on the middle part, and they are distributed to the sorted grain outlet in the direction almost perpendicular to the direction of shaking. The brown rice flows down to a brown rice passage 8 provided at the discharge port, the unhulled brown rice mixed grains flow down to the unhulled brown rice mixed grain passage 9, and the unhulled rice flows down to the unhulled rice passage 10. The mixed grains of paddy and brown rice are returned to the mixed grain receiving trough 13 of the rice husk wind sorting room 5 from the discharge passage 11 at the end of the mixed grain passage 9 via the circulation circuit 12, and the brown rice is returned from the brown rice discharge port 14 at the end of the brown rice passage 8. Weight contaminants such as earth and sand that have flowed down to the stone removal sorting section 15 are separated, and the selected brown rice is fried to a predetermined height through the rice-lifting discharge channel 16 and taken out of the machine. This is a hulling and sorting device that is formed so that the rice is returned to the supply port 2 from a discharge passage 17 at the end of the passage 10 via a lifted rice discharge passage 18 and then taken out again. And the stone removal sorting section 15
A swing mechanism 21 is connected to a sorting machine frame 20 whose bottom wall is formed on the surface of a porous wall sorting plate 19, and a grain discharge port 22 provided on one side of the machine frame 20 is connected to the lifted rice discharge path 18. The supply port 24 of the grain thrower 23 provided in
A sand particle discharge port 25 provided at the end of the swinging side of the porous wall sorting plate 19 is provided to protrude outside the machine, and a wind turbine box 27 with a built-in wind turbine 26 is provided on the lower surface of the porous wall sorting plate 19. is attached to the rotating shaft 28 of the windmill 26 or the swinging mechanism 21 of the porous wall sorting plate 19.
is connected to a rotation mechanism 30 provided in a machine frame 29 containing the rice husk wind sorting chamber 5, and 31 is a porous wall sorting plate 19.
This is the supply port provided at the top of the.

With the above-mentioned configuration, the sorted brown rice flowing on the higher side of the oscillating sorting plate 7 flows down to the brown rice passage 8 provided at the end of the sorting plate, and passes through the brown rice discharge port 14 at the end of the passage through the porous holes in the stone removal sorting section 15. The brown rice falls onto the wall sorting plate 19, and due to the blast action of the sorting plate, the brown rice floats up on the plate surface and slides down, flowing out from the grain outlet 22 provided at the end of the swinging side, and removing the weight of earth and sand. Contaminants are sent upward by the rocking motion of the plate surface and discharged outside the machine from the soil grain discharge port 25 provided at the end of the rocking side, and the selected brown rice flowing out from the grain discharge port 22 is used for threshing. The grains are fried by the thrower 23, stored in a container (not shown), etc., and sent to the next process.

In this way, the rice hulling sorting device of the present invention includes a hulling section,
Heavy foreign substances such as soil and sand mixed into the brown rice sorted through the sorting air path and the oscillating sorting section are completely removed by the stone removal sorting section installed in the brown rice discharge process, so the above-mentioned The quality of sorted brown rice can be greatly improved by eliminating the harmful effects, and since the rotating shaft of the windmill or the swinging mechanism of the porous wall sorting plate is connected to the rotating mechanism provided in the machine frame, the rotating mechanism can be simplified. In addition, the entire device can be made compact and small, and it always exhibits high-precision sorting performance to ensure reliable, smooth, and quick mass production of high-quality selected brown rice.
