[0003] Soybean screening is a multi-step process for processing mature soybeans, which aims to remove impurities and unqualified shriveled beans from harvested soybeans, and separate high-quality full beans. In practical application, when the soybeans are initially screened, high-quality full beans, ordinary-sized soybeans and small shriveled soybeans are separated and usually stored in respective storage mechanisms, and then discharged after the initial screening is completed. However, in the prior art, the automatic soybean screening is a continuous process, which has a large amount of work. If the discharge is not timely, the internal accumulation will be blocked, affecting the operation. In addition, when the broken soybean shells and small stones in the soybeans are screened out, a common filter plate is usually used to make them fall down. However, the soybean shells are light in weight and difficult to fall down and collect by themselves, which needs to be improved. SUMMARY

[0009] The classification structure further comprises a second feeding port arranged on both sides of the rectangular pipe and connected with the screen plate one; a first material guide port and a second material guide port respectively arranged on both sides of the processing box and corresponding to the screen plate two and the material guide plate; and an outlet arranged on the lower end of the rectangular pipe.
[0010] Further, the baffle one and the baffle two are both inclined and have opposite inclined directions, and the lower end of the baffle two is lower than that of the baffle one.
[0011] Further, the collection box is detachably connected with the air outlet pipe through bolts.
[0012] Further, the guide plates are symmetrically arranged and in inverted V shape, and the guide plates are all arranged below the material falling port.
