Description

Technical Field

[0001] This utility model relates to the field of grain processing, specifically a grain screening device for millet processing. Background Technology

[0002] Millet raw materials often contain impurities such as stones, soil, grass clippings, and straw, and may even contain metal fragments. The primary screening device can quickly separate these impurities to prevent them from affecting the purity of the finished millet product and to prevent them from damaging the equipment during subsequent processing. Therefore, it is necessary to screen the millet.

[0003] Currently, the most common method for initial screening of millet is to use a filter screen to separate the millet as it falls. However, because the millet tends to concentrate in the middle of the filter screen when it falls, while the material is sparse in the edge areas, the utilization rate of the screen surface is low, and the filter screen in the middle part is prone to clogging.

[0004] Therefore, a grain screening device for millet processing is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a grain screening device for millet processing, including a base plate 1. Several support frames 2 are fixedly installed on the top edge of the base plate 1. Springs 3 are provided inside the support frames 2. A bottom frame 4 is movably installed on the top of the support frames 2. Several screen cylinders 5 are fixedly installed on the top of the bottom frame 4. An inverted conical guide plate 6 is fixedly installed in the middle part of the bottom of the inverted conical guide plate 6. A drive motor 7 is fixedly installed in the middle part of the bottom of the inverted conical guide plate 6. Several connecting rings 8 are sleeved on the surface of the output end of the drive motor 7. An arc-shaped scraper 9 is fixedly installed on one side of the connecting ring 8.

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Through the structural design of support frame 2, spring 3, bottom frame 4, screen cylinder 5, drive motor 7, connecting ring 8, and arc scraper 9, and through the cooperation between the structures, the screening function is improved. Thus, the millet can be evenly distributed on the surface of screen 12 by vibration and disturbance of the accumulated millet, thereby improving screening efficiency.

[0020] A T-shaped limiting rod 10 is fixedly installed on the other side of the connecting ring 8, and a cleaning brush 11 is fixedly installed on the surface of the T-shaped limiting rod 10.

[0021] Reference Figure 1 , Figure 2 , Figure 4 The T-shaped limiting rod 10 facilitates the fixing of the cleaning brush 11 and restricts its running trajectory, ensuring that the cleaning brush 11 accurately fits the surface of the screen 12, while preventing the parts from shifting when rotating. The cleaning brush 11 can easily rotate with the T-shaped limiting rod 10 to clean the screen holes that are blocked on the surface of the screen 12, keeping the screen 12 transparent and ensuring screening efficiency.

[0022] A screen 12 is fixedly installed in the middle of the inner cavity of the screen cylinder 5, and a discharge pipe 13 is fixedly installed on one side of the screen cylinder 5.

[0023] Reference Figure 1 , Figure 2 , Figure 4 The screen 12 facilitates the separation of millet from impurities by utilizing the sieve holes, and simultaneously screens millet of different sizes. The discharge pipe 13 facilitates the discharge of qualified millet or separated impurities from the screen cylinder 5, achieving directional output of materials and facilitating the connection with subsequent processes.

[0024] Several discharge ports 14 are provided on the edge of the inverted cone-shaped guide plate 6.

[0025] Reference Figure 3 The discharge port 14 facilitates the discharge of impurities after final screening, thereby reducing the amount of impurities remaining inside the device.

[0026] A T-shaped rod 15 is fixedly installed at the bottom edge of the bottom frame 4, and the T-shaped rod 15 is sleeved onto the top of the support frame 2.

[0027] Reference Figure 2 and Figure 3 The T-shaped rod 15 facilitates the connection between the bottom frame 4 and the support frame 2, while also limiting the spring 3, thereby ensuring the effective transmission of subsequent vertical vibration force.

[0028] Several limiting nuts 16 are fixedly installed on the top of the support frame 2 and on the top of the T-shaped rod 15.

[0029] Reference Figure 1 The limiting nut 16 helps to limit the vibration amplitude of the bottom frame 4, preventing excessive vibration from causing parts to fall off or be damaged.

[0030] Working principle: When using this device, millet raw material is fed into the top screen cylinder 5 from the top. After being blocked by the top screen 12, the output end of the drive motor 7, in conjunction with the connecting ring 8, drives the arc-shaped scraper 9 to push the accumulated millet. At the same time, the vibration force generated by the drive motor 7 causes the bottom frame 4 to vibrate. The bottom frame 4, in conjunction with the T-shaped limit rod 10, presses the spring 3. The tension of the spring 3 drives the entire device to vibrate vertically. After being pushed by the arc-shaped scraper 9, the millet completely covers the top screen 12 and undergoes preliminary filtration through the top screen 12. The filtered millet is then screened again through the bottom screen 12. The material blocked by the screen 12 is gradually pushed to the discharge pipe 13 by the rotating arc-shaped scraper 9.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
