[0002] In agricultural production, the processing of legumes is an important link. Whether as food, feed, or processed into other products, the quality of legumes directly affects the quality and market value of the final product. In the process of legume processing, screening is an indispensable step, which is used to remove impurities and substandard particles in legumes to ensure the purity and consistency of the product. The traditional legume screening device usually adopts a fixed sieve plate structure, which uses the sieve holes on the sieve plate to screen out impurities and substandard particles.
[0003] However, the principle of using this traditional device is the comparison of legume particle size and sieve hole size. The particles smaller than the sieve hole diameter are screened to one side, while the particles larger than the sieve hole diameter are screened to the other side. The most significant problem in actual use of this method is that when the sieve hole diameter is the same as or similar to the particle size, the sieve hole is easy to be stuck in the legume, causing clogging, which seriously affects the screening effect and efficiency. In this case, either the new sieve plate needs to be disassembled and replaced, or the original sieve plate needs to be cleaned and reused. No matter which way, the operation is more troublesome, and the screening process needs to be interrupted to a large extent, which affects the normal screening efficiency. To solve the above problems, a new type of legume screening device is needed to prevent clogging. SUMMARY
[0004] The technical problem to be solved by the utility model is that when the sieve plate of the legume screening device is clogged, whether it is replaced or the clogged sieve hole is cleaned, it is more troublesome and easy to interrupt the screening process for a long time, affecting the screening efficiency.
