[0002] Red bean screening refers to the process of separating impurities and defective products from qualified red bean raw materials using physical, mechanical, or photoelectric methods. It is a crucial preliminary step in the red bean processing industry chain to ensure product quality. In the food processing field, the presence of impurities not only affects the taste and safety of red bean products but may also damage subsequent processing equipment. In the seed breeding field, mixed foreign particles can directly reduce the purity of red bean varieties. With the increasing market demand for red bean quality and the large-scale growth of red bean processing capacity, efficient and precise screening and impurity removal technology has become an urgent need for the industry's development.

[0003] Currently, most red bean screening and impurity removal technologies rely on a single screen structure. Traditional screens can only separate some impurities based on particle size differences. They are difficult to effectively identify and remove stones, metal fragments, moldy beans, or discolored particles with similar particle size to red beans, or those with similar density. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an automatic impurity removal structure in the red bean screening process, which effectively solves the problem of poor impurity removal effect in the current red bean screening process.

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figure 1-4This utility model relates to an automatic impurity removal structure in the screening process of red beans, including a box body 1. A top frame 14 is fixedly connected to the top of the box body 1. A screen 20 is provided inside the top frame 14. A wind duct 3 is fixedly connected to the outside of the box body 1. A fan 17 is fixedly installed inside the wind duct 3. A filter 16 is provided inside the wind duct 3. The fan 17 is located on the side of the filter 16 closer to the box body 1. The filter 16 is fixed inside the wind duct 3 with bolts to prevent dust from entering the box body 1 and to allow for disassembly and cleaning of the filter 16. A duct 4 is fixedly connected to the wind duct 3. The end of the duct 4 away from the wind duct 3 extends into the box body 1 and is fixedly connected to a hollow plate 6. The side of the hollow plate 6 away from the duct 4 has multiple air outlets 13. A hopper 10 is fixedly connected inside the box body 1. The hopper 10 is located on the side of the hollow plate 6 away from the duct 4. A discharge pipe 11 is fixedly connected to the hopper 10. The discharge pipe 11 is located away from the hopper 10. One end extends to the outside of the box 1. Inside the box 1, a screen 9 is movably installed below the hopper 10. The screen 9 is inclined and a sloping plate 7 is fixedly connected to the screen 9. A vibration mechanism 2 is provided on the top of the sloping plate 7. Two positioning blocks 19 are symmetrically fixedly connected to the top of the top frame 14. Two positioning plates 18 are symmetrically fixedly connected to the top of the screen 20. The two positioning plates 18 are respectively fitted on the outside of the two positioning blocks 19. The cooperation between the positioning plates 18 and the positioning blocks 19 facilitates the support of the screen 20 and allows the screen 20 to be disassembled and cleaned. The inside of the box 1 is fixedly connected to the two sides of the flow guide plate 15 and the flow guide plate 12 respectively. The hopper 10 is fixed to the bottom of the flow guide plate 12. The hollow plate 6 is located below the flow guide plate 15. Inside the box 1, there is a drawer 5 and a drawer 8. The drawer 8 is located below the screen 9 and the drawer 5 is located below the sloping plate 7.

[0024] In operation, red beans are first poured into the top frame 14 and screened through the second screen 20 to separate larger impurities such as branches and pods. The red beans are then guided by the second guide plate 15 and the first guide plate 12 through the hollow plate 6 and the hopper 10. At the same time, the blower 17 is started, allowing outside air to enter the hollow plate 6 through the air duct 3 and the air pipe 4 and be discharged from each air outlet 13, thus achieving air separation of the red beans. Light impurities such as withered leaves and light plastic pieces enter the hopper 10 and are discharged from the discharge pipe 11. The red beans then fall onto the first screen 9, while fine impurities such as sand and soil pass through the first screen 9 and fall into the second drawer 8 for collection. The red beans on the first screen 9 fall into the first drawer 5 under the action of gravity through the inclined plate 7 for collection, thus improving the impurity removal effect.

[0025] Specifically, by Figure 5The vibration mechanism 2 includes an inner plate 201 fixed inside the housing 1. The inner plate 201 is fixedly sleeved on the outside of the air duct 4. Two columns 203 are symmetrically fixedly connected between the top of the inner plate 201 and the guide plate 15. A bracket 205 is movably sleeved between the two columns 203. The bracket 205 is fixed to the top of the inclined plate 7. A vibrator 204 is fixedly installed on the top of the bracket 205. Two springs 202 are symmetrically fixedly connected between the inner plate 201 and the bracket 205. The two springs 202 are respectively sleeved on the outside of the two columns 203.

[0026] In use, the vibrator 204 is started first, which drives the bracket 205 to vibrate. Under the action of the elastic force of the two springs 202, the bracket 205 slides back and forth along the two columns 203. The inclined plate 7 drives the screen 9 to vibrate, which prevents the screen 9 from getting blocked. Finally, the red beans on the screen 9 fall quickly into the drawer 5 for collection.
