[0003] The existing wind screen type seed cleaning machine blows away the lighter debris such as bran in the seeds by wind selection. However, in the process of blowing away, a small amount of smaller seeds will still follow the bran into the debris pile, which easily leads to seed waste when the debris is discarded. At the same time, when the seeds to be cleaned are directly fed from the feed port, a large number of seeds will pass through the exhaust port in a short time, which may lead to incomplete separation of the debris in the seeds, affecting the final effect of seed cleaning.
