Description

Technical Field

[0001] This utility model relates to the field of rice production, and more specifically, it relates to a screening device for rice production. Background Technology

[0002] Rice is a very common food in people's lives. Eating rice can meet people's daily energy needs and facilitate their daily lives. In the rice production process, it is often necessary to screen rice to separate rice grains of different sizes. Therefore, screening devices are needed to screen rice. Existing screening devices generally use rollers or vibrating screens to screen rice. In particular, the roller method uses the rotation of the roller to screen rice. However, when adding rice to be screened into the roller, it is often done by making holes in the roller and setting up a fan door to add and remove the raw material. However, the hole method is only suitable for adding raw material, but it is difficult to remove raw material. Therefore, it is inconvenient to collect the rice remaining after screening. At the same time, during the roller screening process, some rice may get stuck in the screening holes of the roller, which is inconvenient to clean, thus affecting the screening effect of rice.

[0031] In this embodiment, the main structure of the entire screening device is formed by the base plate 1, the first support frame 2, and the second support frame 5.

[0032] More specifically, the screening structure facilitates the screening of rice, and the cleaning structure facilitates the cleaning of the screening bucket 4.

[0033] Please see Figures 1-5As one implementation method for rice screening: The mounting frame 3 has first rotating columns 9 fixedly installed at both ends; the first support frame 2 has first rotating holes 10; the screening barrel 4 has screening holes 11, with multiple screening holes 11; both ends of the screening barrel 4 have passage openings 12; the first rotating columns 9 and the first rotating holes 10 cooperate with each other and are rotatably connected; the side end of the first support frame 2 is fixedly installed with a first motor 13, and the output end of the first motor 13 is fixedly connected to the first rotating column 9; both ends of the screening barrel 4 are provided with cover plates 14, which are detachably connected to the screening barrel 4; the lower end of the cover plate 14 is fixedly provided with a sealing block 15, which cooperates with the passage opening 12 and is threadedly connected to the passage opening 12; both ends of the screening barrel 4 are fixedly installed with second rotating columns 16; the mounting frame 3... The upper part has a second rotating hole 17, and the second rotating column 16 and the second rotating hole 17 are mutually engaged and rotatably connected. The screening bucket 4 is provided with positioning holes 18 on the side end of the second rotating column 16 and the mounting frame 3 is provided with positioning holes 18 on the side end of the second rotating hole 17. The positioning holes 18 of the mounting frame 3 are provided with positioning rods 19. There are multiple positioning holes 18, and the positioning holes 18 are provided with threads. The positioning rods 19 are threadedly connected to the positioning holes 18. The fixed frame 6 has a third rotating hole 20. The cleaning wheel 7 is provided with a cleaning brush 21.

[0034] Specifically, when rice is placed into the screening bin 4, the cover plate 14 is removed from the passage 12 by the cooperation of the sealing block 15 and the cover plate 14. The rice to be screened is added into the passage 12. After the rice is added, the cover plate 14 is reinstalled on the screening bin 4 by the threaded connection between the sealing block 15 and the passage hole. The first motor 13 on the first support frame 2 drives the first rotating column 9 to rotate, thereby driving the screening bin 4 of the mounting frame 3 to rotate. The rice is screened through the screening holes 11 on the screening bin 4, which facilitates the addition of rice into the screening bin 4 and the placement and screening of rice. After the rice screening is completed, the positioning rod 19 is rotated so that the positioning rod 19 is aligned with the screening bin 4. The positioning holes 18 on the upper part are separated, so that the positioning rod 19 no longer restricts the screening barrel 4.

After the rice screening is completed, the electric push rod 8 on the second support frame 5 extends and drives the fixed frame 6 to move, so that the cleaning brush 21 on the cleaning wheel 7 can contact the screening hole 11 opened on the screening barrel 4. The second motor 23 drives the cleaning wheel 7 to rotate, and at the same time the first motor 13 drives the screening barrel 4 to rotate, thereby cleaning the remaining rice in the screening hole 11 of the screening barrel 4.

[0035] In summary, when using it as a whole:

[0036] When rice is placed into the screening bin 4, the cover plate 14 is removed from the passage 12 by the cooperation of the sealing block 15 and the cover plate 14. The rice to be screened is added into the passage 12. After the rice is added, the cover plate 14 is reinstalled on the screening bin 4 by the threaded connection between the sealing block 15 and the passage hole. The first motor 13 set on the first support frame 2 drives the first rotating column 9 to rotate, thereby driving the screening bin 4 of the mounting frame 3 to rotate. The rice is screened through the screening holes 11 set on the screening bin 4, which makes it easy to add rice into the screening bin 4 and facilitates the placement and screening of rice.

[0037] After the rice is screened, rotate the positioning rod 19 to separate it from the positioning hole 18 on the screening barrel 4. This removes the restriction of the screening barrel 4 by the positioning rod 19. The screening barrel 4 is then rotated by the cooperation of the second rotating column 16 and the second rotating hole 17, causing the screening barrel 4 to stand upright. The cover plate 14 at the bottom of the screening barrel 4 can then be removed, making it easier to take out the remaining rice from the screening barrel 4.

[0038] After the rice is screened, the electric push rod 8 on the second support frame 5 extends and drives the fixed frame 6 to move, so that the cleaning brush 21 on the cleaning wheel 7 can contact the screening hole 11 on the screening barrel 4. The second motor 23 drives the cleaning wheel 7 to rotate, and at the same time the first motor 13 drives the screening barrel 4 to rotate, thereby cleaning the rice remaining in the screening hole 11 of the screening barrel 4.
