The baffle 17 and the moving block 15 have matching specifications. The baffle 17 and the moving block 15 are slidably connected, and the brush 18 can scrape on the inclined filter screen 13.

[0027] Embodiment 2

[0028] See also Figure 1-2 A collecting box 5 is provided on the surface of the shell 1, and a handle 6 is fixedly installed on the surface of the collecting box 5. A rolling groove 7 is opened inside the shell 1, and a ball 14 is fixedly installed on one end of the collecting box 5 close to the rolling groove 7, which can collect the fallen soil and facilitate the subsequent cleaning of the staff. The collecting box 5 is slidably connected to the shell 1. When the collecting box 5 is full, the collecting box 5 can be drawn out for cleaning.

[0029] Working principle: When using the rice stone removing machine, the staff first starts the stone removing machine, then pours the rice to be processed from the discharge port 4, starts the motor B19, and the fan blades 20 blow into the shell 1 through the air duct 9, so that the lighter impurities in the rice are separated from the rice, and the lighter impurities fall into the dust collecting frame 10, and then in the screening process, the motor A3 is started to drive the moving block 15 to slide along the round rod 12. While moving, the moving block 15 drives the internal brush 18 to move together. The brush 18 can effectively scrape the surface of the filter screen 13. At the same time, the internal spring 16 will shrink backward when it is under pressure, so the brush 18 can scrape on the inclined filter screen 13. The brush 18 can effectively scrape the surface of the filter screen 13. The scraper plate scrapes the attachments on the filter screen 13 to prevent the filter screen 13 from being blocked and affecting the screening effect. The soil that falls after screening falls into the collection box 5. After the collection box 5 is full, the collection box 5 can be extracted to facilitate the subsequent cleaning of the staff.
