AI Technical Summary
Existing intelligent rice screening systems are prone to uneven screening during the screening process, resulting in impurities, discolored grains, and imperfect grains being mixed inside high-quality grains, which affects the quality of subsequent rice processing.
The system employs a multi-layer filter plate structure, including a first filter plate, a second filter plate, and a third filter plate. In conjunction with a rotating rod and a conveying auger, the rice is screened and conveyed multiple times through the cooperation of multi-stage filtration and the conveying auger, ultimately collecting high-quality rice, low-quality rice, and medium-quality rice separately.
This improves the uniformity and precision of rice screening, ensuring that high-quality rice is not mixed with medium- or inferior rice, thus enhancing the overall quality of rice processing.

Therefore, an intelligent rice screening system is needed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing intelligent rice screening systems often result in uneven screening during the screening process, which leads to some impurities, discolored grains, and imperfect grains being mixed inside high-quality grains, easily affecting the quality of subsequent rice processing. Therefore, this invention proposes an intelligent rice screening system.

High-quality rice falls into the first arc plate, the lowest quality rice into the third arc plate, and medium-quality rice into the second arc plate. A conveyor auger then transports the rice. The high-quality and medium-quality rice are further filtered through the arc plates and fall onto the lower inclined plate. The rice on the inclined plate slides onto one side of the arc plate, achieving a secondary filtration effect. This prevents the high-quality rice from being mixed with medium-quality or low-quality rice, thus improving the sieving effect. Attached Figure Description

[0024] The overall effect of embodiment 2 is as follows: Support legs 2 are fixedly connected to the bottom of the screening chamber 1 near its four corners. The bottoms of the support legs 2 are trapezoidal, which supports the bottom of the screening chamber 1. Baffles 8 are fixedly connected to one end of the first filter plate 5 and the third filter plate 7, which prevents rice from entering the grooves 9. Grooves 9 are formed on both inner walls of the screening chamber 1 near the baffles 8. Movable plates 10 are installed inside the grooves 9 and fixedly connected to the baffles 8.

The top of the vertical plate 18 is embedded in the groove 13 and slidably connected to it, which can prevent the screened rice from entering the side arc plate.
[0025] Working principle: Rice is placed into the screening box 1 through the feed hopper 23. The rice slides and is filtered and screened on the first filter plate 5, the second filter plate 6, and the third filter plate 7. The high-quality rice falls into the first arc plate 14, the lowest quality rice falls into the third arc plate 16, and the medium-quality rice falls into the second arc plate 15. At this time, the drive motor 24 drives the rotating rod 19 to rotate, which in turn drives the conveying auger 20 to rotate. During the conveying of rice, high-quality rice mixed with medium-quality and low-quality rice will be filtered through the filter arc plate 17. The filtered medium-quality and low-quality rice will fall onto the lower inclined plate 25 and slide into the lower second arc plate 15. The medium-quality mixed with low-quality rice in the second arc plate 15 will also be filtered through the filter arc plate 17. The filtered low-quality rice will enter the third arc plate 16. At this time, the conveying auger 20 can discharge the sorted rice through the discharge hole 21.
