[0002] In the rice processing industry, screening is a core step. Its function is to separate rice of different particle sizes, thereby ensuring the quality of rice. At the same time, high-quality rice can be sold at a better price. Currently, the most common rice screening devices on the market are vibrating screens or drum screens. Vibrating screens rely on motors to drive the screen body to vibrate, causing the rice to jump on the screen surface to achieve separation.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This application provides a high-precision screening device for rice processing, including a base plate 1, a support component 2 is provided on the upper end of the base plate 1, and the support component 2 is provided in four groups. A screening component 3 is provided between the four groups of support components 2. A mounting frame 6 is provided on the upper end of the screening component 3. A motor 7 is provided on the upper end of the mounting frame 6. An eccentric block 8 is fixedly connected to the output end of the motor 7.
[0039] Specifically, the support assembly 2 includes uprights 21, a support plate 22, a spring 23, and a side plate 24. The uprights 21 are fixedly connected to the upper end of the base plate 1, the support plate 22 is fixedly connected to the upper end of the uprights 21, the spring 23 is fixedly connected to the upper end of the support plate 22, and the side plate 24 is fixedly connected to the upper end of the spring 23. The two sets of uprights 21 closer to the upright plate 9 are longer than the two sets of uprights 21 farther from the upright plate 9, thereby maintaining the inclination of the screening assembly 3.
[0040] Specifically, the screening component 3 includes a screen frame 31, a partition 32, and a screen 33. The screen frame 31 is fixedly connected to the side plate 24. The partition 32 is fixedly connected inside the screen frame 31, and multiple sets of partitions 32 are provided. The screen 33 is fixedly connected inside the screen frame 31, and multiple sets of screens 33 are provided. The screen 33 is fixedly connected to the front partition 32, and the mesh size of the screen 33 increases from low to high.
[0041] Specifically, a feeding trough 4 is provided on the right side of the screen frame 31, and a feeding pipe 5 is fixedly connected to the right side of the screen frame 31. The feeding pipe 5 is connected to the feeding trough 4.
[0042] Specifically, a vertical plate 9 is fixedly connected to the upper end of the base plate 1, a connecting plate 10 is fixedly connected to the front of the vertical plate 9, and a hopper 11 is fixedly connected to the front of the connecting plate 10.
[0043] Specifically, a connecting rod 12 is fixedly connected inside the upright plate 9, and a rotating plate 13 is rotatably connected to the side of the connecting rod 12.
[0044] Specifically, a slide groove 14 is provided through the right side of the rotating plate 13, and a limit rod 15 is slidably connected inside the slide groove 14.
[0045] Specifically, the left and right ends of the limiting rod 15 are rotatably connected to the sliding rod 16, and the sides of the sliding rod 16 are slidably connected to the limiting plate 17, which is fixedly connected inside the hopper 11.
[0046] Specifically, a baffle block 18 is fixedly connected to the bottom of the slide bar 16. The baffle block 18 is slidably connected to the bottom discharge port of the hopper 11. The discharge of rice can be controlled by moving the baffle block 18 up and down.
[0047] Specifically, a force-bearing block 19 is fixedly connected to the front end of the rotating plate 13. The bottom of the force-bearing block 19 abuts against the eccentric block 8. The force-bearing block 19 can be moved up and down by rotating the eccentric block 8.
[0048] With the above structure, the high-precision screening device for rice processing provided in this application can cause the screening component 3 to vibrate between the four sets of support components 2 by rotating the eccentric block 8 driven by the motor 7. At this time, the rice is poured onto the top of the highest screen 33. The largest rice grains can be screened out through the screen 33, and the remaining rice falls to the top of the next layer of screen 33 for screening. At this time, the rice can be screened in multiple layers with high screening accuracy.
[0049] When the eccentric block 8 rotates, it will squeeze the force block 19. At this time, the force block 19 can move up and down. The force block 19 can drive the rotating plate 13 to swing up and down around the connecting rod 12. When the rotating plate 13 swings, it can drive the limiting rod 15 to move up and down. At this time, the baffle block 18 can move up and down synchronously. When the baffle block 18 moves upward, the rice inside the hopper 11 can flow out through the gap between the baffle block 18 and the hopper 11. When the baffle block 18 moves downward, it can seal the bottom of the hopper 11. This structure makes it easy to control the feeding according to the vibration frequency of the screening component 3.

These embodiments are merely illustrative and are intended to help understand the method and core concepts of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
