[0002] After rice is harvested from the field, it needs to be screened to remove stones, mud, grass clippings and other debris from the rice. Usually, a screening machine is used for this operation during processing. Common screening machines use the different specific gravities of stones and rice to separate rice and stones using a vibrating screen.

[0003] A Chinese utility model patent discloses a discharging mechanism for a rice screening machine, with the publication number CN219880526U, which includes a screening box, a discharging cylinder is fixedly connected to one end of the guide cylinder away from the screening box, a second rotating shaft is rotatably connected to the inner wall of the discharging cylinder, a second threaded conveying blade is fixedly connected to the outer wall of the second rotating shaft, a driving motor is fixedly installed on the outer wall of the side of the discharging cylinder away from the discharge port, and the output pumping end of the driving motor passes through the discharging cylinder and is fixedly connected to one end of the second rotating shaft. In the utility model, the output shaft of the driving motor can drive the second rotating shaft to rotate, and then drive the second threaded conveying blade to rotate, and the rice falling from the guide cylinder is transported. When the second threaded conveying blade rotates, the rice is continuously squeezed toward the discharge port of the discharging cylinder, effectively preventing the rice from being blocked at the discharge port of the discharging cylinder when discharging. However, the device has certain defects, and it is impossible to screen the debris and dust in the rice during screening, which makes the screening effect poor.
