[0001] This utility model relates to the field of rice processing technology, specifically to a rice processing chaff removal device. Background Technology
[0002] During rice processing, specialized machinery is used to peel off the outer husk of the paddy through friction and cutting, directly removing the bran layer attached to the surface of the rice grains. This reduces the risk of oxidation during storage, prevents mold and pests, and extends the shelf life of the rice.
[0003] Application No. 202120809278.9 discloses a rice processing bran removal device. By using a rotating motor to drive a rotating shaft, the flow rate regulating plate is rotated, thereby controlling the flow rate of the rice bran to be separated. In this way, the flow rate of the mixed rice bran falling onto the bran removal filter screen is limited, which can be separated more thoroughly and effectively solves the problem of incomplete separation caused by excessive feed flow.
[0004] The filter screen in the above application is tilted, which can easily cause rice that has not been fully sieved to be discharged directly along the slope, and the larger rice bran mixed in with the rice is difficult to remove completely. Utility Model Content

[0013] This utility model provides a rice processing bran removal device, which has the following beneficial effects: 1. This rice processing bran removal device uses an arc-shaped filter chamber inside the bran removal box to maintain close contact with a rotating sieve plate. This allows the sieve plate to lift the rice significantly, preventing clogging and ensuring that the rice does not detach from the sieve plate and the filter chamber. This allows for thorough sieving, and the larger volume of rice bran lifted by the fan and conveying pipe is sucked into the collection box, which helps improve the bran removal efficiency.
[0014] 2. The rice processing bran removal device uses an elastic dust cover connected between the rotating end of the sieve plate and the filter chamber to cover the rotating end of the sieve plate, preventing rice and bran from entering the gaps and causing the sieve plate to get stuck. It does not hinder the rotation of the sieve plate, which helps to strengthen the maintenance of the sieve plate and makes it less prone to damage. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Please see Figures 1 to 4This utility model provides a technical solution: a rice processing bran removal device, including a bran removal box 1, an arc-shaped filter chamber 2 inside the bran removal box 1, a collection trough 3 inside the bran removal box 1 and located at the bottom of the arc-shaped filter chamber 2, a rotating shaft 4 rotatably connected inside the arc-shaped filter chamber 2, a sieve plate 5 installed on the outer side of the rotating shaft 4, a sieve screen installed inside the sieve plate 5 to facilitate the sieving of small-volume rice bran from the rice, both ends of the sieve plate 5 are arc-shaped, the edges of the sieve plate 5 fit into the arc-shaped filter chamber 2, the rotating shaft 4 and the center point of the arc-shaped filter chamber 2 are located at the same position, an electric push rod 6 rotatably connected inside the collection trough 3, the output end of the electric push rod 6 rotatably connected to the bottom of the sieve plate 5, so that the rice is sieved. As the electric push rod 6 extends, plate 5 rotates and swings, lifting the rice and bran. This prevents the sieve plate 5 from clogging and ensures the rice doesn't detach from the arc-shaped filter chamber 2, allowing for thorough sieving. An elastic dust cover 13 is fixedly connected inside the arc-shaped filter chamber 2, above the rotating shaft 4. One end of the elastic dust cover 13 is fixedly connected to the sieve plate 5. Made of elastic rubber, the dust cover 13 deforms under pressure, protecting the rotating end of the sieve plate 5 and preventing rice from getting stuck. A discharge port 7 is located inside the bran removal box 1, on one side of the arc-shaped filter chamber 2. This, combined with the tilt of the sieve plate 5, facilitates the discharge of the bran-free rice through the discharge port 7. A collection box 8 is installed on one side of the box 1. A conveying pipe 9 is fixedly connected to the top of the collection box 8. One end of the conveying pipe 9 is fixedly connected to the arc-shaped filter chamber 2. A blower 10 is installed on one side of the chaff removal box 1 and at the bottom of the collection box 8. An air inlet pipe 11 is fixedly connected to the input end of the blower 10. One end of the air inlet pipe 11 is fixedly connected to the collection box 8. The operation of the blower 10 generates suction through the air inlet pipe 11 and the conveying pipe 9, which facilitates the suction of the raised rice bran into the collection box 8 for collection. A filter screen 12 is installed inside the collection box 8 and on one side of the air inlet pipe 11 to intercept the rice bran in the airflow, which helps to prevent it from entering the blower 10. An electric push rod 15 is installed on the top of the collection box 8. A scraper 16 is fixedly connected to the output end of the second rod 15 and to one side of the filter screen 12. The scraper 16 moves up and down with the extension of the electric push rod 15 to scrape off the attached material on the filter screen 12, which helps to prevent the filter screen 12 from clogging. A door 19 is connected to one side of the collection box 8 by a hinge. An electromagnetic lock is provided between the door 19 and the collection box 8 to facilitate the opening of the door 19 and the discharge of rice bran in the collection box 8. Inside the bran box 1, at the top of the arc-shaped filter chamber 2 and at the bottom of the collection trough 3, a feed hopper 17 and a discharge pipe 14 are fixedly connected respectively. A valve is installed on one side of the discharge pipe 14 to facilitate the loading and unloading of rice and rice bran. A controller 18 is installed on the outer wall of the bran box 1 and at the top of the collection box 8.
[0019] In summary, this rice processing bran removal device works by feeding rice into the bran removal box 1 and the arc-shaped filter chamber 2 through the feed hopper 17. The sieve plate 5 removes smaller rice bran and debris. Simultaneously, the electric push rod 6 rotates rapidly, pushing the sieve plate 5 to rotate repeatedly at a certain angle, above the discharge port 7. While repeatedly lifting the rice, the sieve plate 5 remains in contact with the arc-shaped filter chamber 2, ensuring the rice stays on the sieve plate 5 for thorough sieving. The blower 10 generates suction through the air inlet pipe 11 and the conveying pipe 9. Due to the weight of the rice bran... Because it is relatively light, the conveying pipe 9 sucks the raised rice bran into the collection box 8, and the filter screen 12 in the collection box 8 intercepts the rice bran. After it is collected in the collection box 8, the electric push rod 2 15 pushes the scraper 16 up and down to scrape off the rice bran attached to the filter screen 12. After that, the electric push rod 1 6 drives the sieve plate 5 to tilt downwards so that one end of the sieve plate 5 is aligned with the discharge port 7, so that the rice after the bran is removed can be discharged into the holding container. Both the electric push rod 2 15 and the electric push rod 1 6 are equipped with telescopic dustproof sleeves to protect the piston rod of the electric push rod.
