The invention discloses a wheat screen inner hole sieve cleaning impurity removal and obstacle avoiding device. The wheat screen inner hole sieve cleaning impurity removal and obstacle avoiding devicestructurally comprises a first-order separator, a second-order separation vibration plate, a composite discharging port, damping columns and a joint control box. The first-order separator is closelyattached to the top of the second-order separation vibration plate, and the joint position is fixed through a bolt with a fastening spring. The second-order separation vibration plate and the composite discharging port in the right side are closely buckled. In conclusion, after improvement, wheat is sufficiently spread to a vibration filter net through the first-order separator, and centralized impurity treatment is facilitated through the semi-arc filter net; and meanwhile, inner hole dredging heads clean meshes, prone to being blocked by grass peduncles, at the front end, the clamped grass peduncles are dragged out i
