[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1, Figure 4 and Figure 5 , an embodiment provided by the present utility model: a large-output soybean cleaning and grading sieve, including a frame 1. A filter plate is fixedly connected to the top of the frame 1 for screening out large impurities. The filter plate is used for initially screening out larger impurities, and these impurities are effectively removed before entering the subsequent grading and screening, ensuring the smoothness of the soybean cleaning process. The frame 1 is an enclosed negative-pressure box body. This design can ensure that dust will not overflow during the cleaning and grading process, reducing environmental pollution. A folding flow plate 2 is fixedly connected to the top of the frame 1. Through a specific structural design, the flow path of soybeans during the screening process is more reasonable, effectively improving the screening efficiency. A material distribution plate 3 is fixedly connected to the middle of the frame 1. The material distribution plate 3 can be adjusted, so that the equipment can better screen soybeans. A plurality of upper sieve frames 4 are fixedly connected to the top of the frame 1.

[0024] Two lower sieve frames 7 are fixedly connected to the bottom of the frame 1. These sieve frames are mainly used for screening smaller-sized beans or impurities. Through cooperation with the upper sieve frames 4, the precise grading of soybeans is further completed. The bottom of the two upper sieve frames 4 is fixedly connected with forward flow plates 9. These flow plates are responsible for guiding the materials passing through the sieve mesh to the next screening area, ensuring the smooth connection between the flow direction of the materials and the screening process.

[0025] Reference Figures 1 to 3 , the right end of the bottom of the two upper sieve frames 4 is fixedly connected with a V-shaped guide trough 10. The guide trough is designed in a V shape to guide the screened materials to smoothly enter the next screening link, while reducing the overflow or loss of materials. The bottom of one of the lower sieve frames 7 is fixedly connected with another forward flow plate 9, and the right end of the bottom of one of the lower sieve frames 7 is fixedly connected with another V-shaped guide trough 10.

[0026] Reference Figure 1 A material distribution component for material distribution is fixedly connected to the left end of the frame 1. The material distribution component includes a first material distribution door 11. The right end of the first material distribution door 11 is fixedly connected to the left end of the frame 1. A second material distribution door 12 is fixedly connected to the left end of the frame 1 for initially distributing the flow direction of materials to evenly distribute them to each screening area. A collection component for collection is fixedly connected to the right end of the frame 1. The collection component includes a first collection funnel 5. The outside of the first collection funnel 5 is fixedly connected to the right end of the frame 1. The outside of the first collection funnel 5 is fixedly connected to the right end of the frame 1, mainly used for collecting the finished soybeans after screening to ensure the neatness and concentration of the output. A slag discharge funnel 8 is fixedly connected to the right end of the bottom of the frame 1 for discharging the waste or impurities separated during the screening process. This design effectively avoids the accumulation of impurities and ensures the long-term stable operation of the equipment. A second collection funnel 6 is fixedly connected to one side of the slag discharge funnel 8. The second collection funnel 6 can collect small beans.

[0027] Working principle: First, soybeans enter the frame 1 through the feeding port. The frame 1 is an enclosed negative-pressure box, which can effectively prevent dust from overflowing. After the soybeans enter the frame 1, they first come into contact with the filter plate at the top. The filter plate preliminarily cleans the soybeans, screening out larger impurities to ensure a smoother subsequent screening process.

[0028] Next, the preliminarily cleaned soybeans are introduced into the upper sieve frame 4. Through the action of the material distribution door 11, the material is evenly distributed to each upper sieve frame 4. In these sieve frames, the soybeans are screened layer by layer according to the particle size. Larger particles remain on the sieve mesh, while smaller particles pass through the sieve mesh and fall into the lower sieve frame 7. The bottom of the upper sieve frame 4 is connected with a forward flow plate 9, which is used to guide the material to the next sieve frame or the material guiding trough, ensuring the continuity of the screening process.

[0029] During the screening process, the V-shaped material guiding trough 10 plays a role to ensure that the smaller particle materials can be smoothly guided to the next screening link, preventing the loss or accumulation of materials. Subsequently, the material enters the lower sieve frame 7 for further classification. This stage mainly processes smaller soybeans, screening out impurities through a finer sieve mesh to finally obtain high-purity soybeans.

[0030] The collecting funnel 5 and the collecting funnel 6 are responsible for collecting qualified soybeans and the impurities separated during the screening process respectively. The qualified soybeans are centrally output through the collecting funnel 5. Finally, the slag discharging funnel 8 is responsible for discharging the waste materials or impurities separated during the screening process from the equipment, ensuring the cleanliness and continuous operation of the system interior. During the whole process, each component works together, enabling the soybean cleaning and grading sieve to operate efficiently and ensuring the screening quality and production efficiency of the soybeans.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
