During these production processes, there will be a lot of dust, including dust, rice grains, and debris of rice husks. Therefore, it is necessary to carry out dust reduction treatment on rice, and thus a dust reduction device for rice production and processing needs to be used.

[0003] For example, a dust reduction device for rice production and processing with the authorization announcement number of "CN220920369U" is provided with a U-shaped block and a collection bag.

When installing it, by pulling the U-shaped block to insert it into the through hole of the annular hoop shape, the collection bag can be quickly installed, and there is no need to use fixing methods such as bolts. The disassembly and installation are relatively convenient. However, when cleaning the dust in the collection bag, since the dust is relatively light, it is easy to disperse to the ground and the air when taken out, reducing the working environment, and the falling speed of rice outside the dust suction pipe is relatively fast, and only part of the dust in the rice can be sucked, resulting in low dust reduction quality.

[0030] Working principle:

[0031] Rice production, processing, stirring and dust removal work:

[0032] When dust removal of rice is required, the rice is poured into the tank body 9 from the feed port 13. Subsequently, first connect the air inlet side of the fan 103 to the clean air storage tank used for dust removal in the outside world, and then connect the external power supply of the fan 103. The fan 103 starts to convey clean air for dust removal into the tank body 9 through the L-shaped pipe 104 and the air outlet 105 (a third filter screen 106 is installed on the inner wall of the air outlet 105 to prevent rice from flowing into the L-shaped pipe 104, and a first filter screen 5 is installed at the right end of the third box body 4 to exhaust air). At the same time, connect the external power supply of the first motor 101. The first motor 101 starts to drive the spiral blade 102 to rotate through the bearing in the tank body 9. In this way, the rice can be continuously stirred upward by the spiral blade 102, and the dust on the rice is blown into the inclined pipe 7 by the air ejected from the air outlet 105. (A second filter screen 8 is installed at the left end of the inner wall of the inclined pipe 7 to prevent rice from flowing into the inclined pipe 7 and can filter and separate the rice and the dust). The dust pushed into the inclined pipe 7 will flow into the third box body 4. In this way, the dust removal work of the rice can be carried out.

[0033] Rice production, processing, discharging and dust collection work:

[0034] When it is necessary to take out the rice after dedusting, turn off the blower 103 and the first motor 101. Then open the door installed on the first box body 12 (the door in the middle of the first box body 12 is fastened by a lock catch). Then open the valves installed in the middle of the two discharge ports 10. In this way, the dedusted rice in the tank body 9 can flow out from the two discharge ports 10 into the feed box 11, and then it can be taken out and collected. When it is necessary to collect the dust in the third box body 4, connect the hose at the upper end of the atomizing nozzle 6 to an external water tank and pump water to the atomizing nozzle 6 through an external water pump for spraying. In this way, the dust in the third box body 4 can be moistened to avoid scattering. Then connect the external power supply of the second motor 202. The second motor 202 starts to drive the threaded rod 203 to rotate in the second box body 201 through a bearing. The rotation of the threaded rod 203 drives the rack 204 to slide downward in the chute machined on the inner wall of the second box body 201. The downward sliding of the rack 204 drives the gear 205 to rotate in the second box body 201 through a bearing. The rotation of the gear 205 drives the straight rod 206 to move counterclockwise. Thus, through the cylinder protruding from the outer wall of the straight rod 206 and the chute machined in the middle of the T-shaped plate 207, the T-shaped plate 207 is driven to slide leftward in the chute machined on the inner wall of the second box body 201. The leftward sliding of the T-shaped plate 207 drives the scraper 208 to scrape leftward in the third box body 4. In this way, the soil in the third box body 4 can be scraped to one side. Then open the door in the middle of the third box body 4 to collect it.
