Abstract
The utility model discloses a thresher quadric-riddling sieve which is equipped with a bracket in the back end of a separating roller, the internal side of the bracket is equipped with an orbit which is equipped with a compound sieve, and the compound sieve is a case-shape sieve net which comprises two layers of metal iron net. In addition, the right side of the sieve net is equipped with a chosen blower and the lower end of the sieve net is equipped with a pulley, the compound sieve is arranged on the orbit of the bracket by the pulley. The right side of the bracket is equipped with a transmission shaft, one end of is equipped with a direction-changing arm, the direction-changing arm is equipped with a guiding pole and a crank, the other end of the crank is connected in the sieve net which is driven to reciprocate-vibrate and shake on the orbit by the guiding pole when working, and the chosen effect is achieved through the quadric-separating of the blower.
