[0026] Specifically, by Figure 3-5The separation mechanism 2 includes a movable frame 201 movably installed inside the discharge port 6. Inside the movable frame 201 is a mounting frame 203, and a screen 202 is fixedly connected inside the mounting frame 203. Two side blocks 2017, both located at the bottom of the movable frame 201, are symmetrically fixedly connected to the outer side of the mounting frame 203. Bolts 2016 are installed between the two side blocks 2017 and the movable frame 201. Through the cooperation between the side blocks 2017 and the bolts 2016, the mounting frame 203 can be disassembled from the movable frame 201, thus facilitating the removal of the screen. The impurities filtered out by the filter 202 are processed. An air duct 2010 is fixedly connected to the outside of the air classifier 1. A filter plate 209 is fixedly connected inside the air duct 2010. A hollow plate 2012 is provided inside the air classifier 1. An air duct 2011 is fixedly connected between the hollow plate 2012 and the air duct 2010. Multiple exhaust ports 2013 are evenly distributed on the side of the hollow plate 2012 away from the air duct 2011. An L-shaped plate 206 is fixedly connected to the outside of the air classifier 1. A drive motor 207 is fixedly installed on the L-shaped plate 206. The drive motor 207 is fixed with... A drive shaft 208 is fixedly connected to the filter plate 209. One end of the drive shaft 208, away from the drive motor 207, passes through the filter plate 209 and is fixedly connected to a fan blade 2023. A driven shaft 204 is rotatably connected between the inner plate 7 and the L-shaped plate 206. A conveyor belt 205 drives the driven shaft 204 and the drive shaft 208. An eccentric block 2015 is fixedly installed on the outer side of the driven shaft 204, located inside the discharge port 6. A U-shaped round rod 2022 is fixedly connected to the top of the movable frame 201. A sleeve plate 2020 is fixedly sleeved on the outer middle of the U-shaped round rod 2022. The core block 2015 is located directly below the sleeve plate 2020. Two lifting plates 2021 are symmetrically fixedly sleeved on the outside of the U-shaped round rod 2022. Two L-shaped round rods 2014 are symmetrically fixedly connected inside the air separator box 1. The two lifting plates 2021 are respectively movably sleeved on the outside of the two L-shaped round rods 2014. An outer ring 2019 is fixedly sleeved on the outside of the L-shaped round rod 2014. A spring 2018 is fixedly connected between the bottom of the outer ring 2019 and the lifting plate 2021. The spring 2018 is sleeved on the outside of the L-shaped round rod 2014.

[0027] In operation, rice is first fed into the feed hopper 4, then falls through the inclined plate 5. Simultaneously, the drive motor 207 is started, driving the drive shaft 208 to rotate, which in turn drives the fan blades 2023 to rotate. This causes outside air to be filtered through the filter plate 209 and enter the air duct 2010. The air then enters the hollow plate 2012 through the air duct 2011 and is discharged from each exhaust port 2013, achieving air separation of the rice. Light impurities are discharged from the impurity discharge port 8, while the rice enters the discharge port 6 and is located at the top of the screen 202. When the drive shaft 208 rotates, it drives the driven shaft 204 to rotate through the conveyor belt 205, which in turn drives the eccentric block 2015 to rotate and impact the sleeve plate 2020. This causes the movable frame 201 to move up and down continuously under the elastic force of the two springs 2018, and causes the screen 202 to vibrate to prevent it from clogging, ultimately improving the rice screening effect.

[0028] Specifically, by Figure 6 The cleaning mechanism 3 includes a through groove 301 opened on the drive shaft 208. An inner rod 303 is fixedly installed in the through groove 301. A bracket 304 is movably sleeved on the outside of the inner rod 303. A second spring 305 is fixedly connected between the bracket 304 and the inner wall of the through groove 301. The second spring 305 is sleeved on the outside of the inner rod 303. Two brush plates 302 are symmetrically installed on the bracket 304. Both brush plates 302 are in contact with the filter plate 209.

[0029] In the initial state, spring 2 305 is compressed, causing the two brush plates 302 to fit tightly against the filter plate 209 under the elastic force of spring 2 305. When the drive motor 207 starts, it drives the drive shaft 208 to rotate, and drives the two brush plates 302 to rotate to clean the surface of the filter plate 209. Finally, the filter plate 209 is cleaned to improve the filtration effect.
