shriveled beans, broken beans and smaller size impurities, with the continuous rotation of the small impurity sieve cylinder 302, the qualified soybeans gradually move to the front end of the small impurity sieve cylinder 302, while the smaller impurities fall through the sieve hole of the small impurity sieve cylinder 302 and fall into the small impurity storage box 6 below, the screened soybeans will move forward from the small impurity sieve cylinder 302 to the soybean storage box 8 inside for storage, that is, the screening of the soybeans is completed, by rotating the supporting column 904, the height of the adjusting column 903 can be adjusted, by rotating the first rotating frame 901 connected inside the second rotating frame 902, the angle of the small impurity sieve cylinder 302 and the large impurity sieve cylinder 301 can be adjusted conveniently, so as to change the residence time of the soybeans in the large impurity sieve cylinder 301 and the small impurity sieve cylinder 302, when the soybeans contain more impurities, only need to adjust the inclination angle of the large impurity sieve cylinder 301 and the small impurity sieve cylinder 302 smaller, so that the large impurity sieve cylinder 301 and the small impurity sieve cylinder 302 can screen the soybeans for a longer time, improve the screening quality, on the contrary, only need to adjust the inclination angle of the large impurity sieve cylinder 301 and the small impurity sieve cylinder 302 larger, improve the screening efficiency of the soybeans with less impurities,Since the small impurity screen cylinder 302 is in active contact with the surfaces of the two rollers 303, and the adjusting column 903 is rotatably connected between the limiting ring 7 through the first rotating frame 901 and the second rotating frame 902, the angle of the large impurity screen cylinder 301 and the small impurity screen cylinder 302 can be conveniently adjusted, avoiding the open flat screen structure of the existing part of the agricultural planting and harvesting soybean screening structure, when the dried soybeans are poured on the top of the open screen without blocking structure, the friction between them and the surface of other objects is reduced, when a large amount of soybeans are concentrated and poured on the open flat screen, they quickly fall under the action of gravity, in the collision moment, the soybeans are easy to bounce to the ground, and the angle of the large impurity screen cylinder 301 and the small impurity screen cylinder 302 can be adjusted according to the amount of impurities in the soybeans, so that the quality and efficiency of soybean screening are conveniently improved.

[0041] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
