[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The impurity screening device for pollen collection realizes shaking and rapid screening by setting up a bidirectional motor, a base, a box and other structures. When the bidirectional motor is started, the bidirectional motor will drive the output shafts at both ends to rotate. Due to the setting of the counterweight block on the outer ring of the output shaft, it will rotate eccentrically in the middle of the base, driving the base to shake eccentrically, and pour the pollen mixture from the feed cover. The pollen mixture will follow the overall eccentric shaking, driving the pollen mixture to rotate and move in the device, and the petals and leaves with heavier weight will move to the outermost circle of the inner circle of the first sieve plate, and will be blocked by the block B when passing through the outlet B, and will flow out through the discharge box C. The remaining anthers and pollen enter the interior of the second sieve plate, achieving a rapid screening effect.

[0012] 2. The impurity screening device for collecting pollen realizes layered screening by arranging the first sieve plate, the second sieve plate, the arc convex plate and other structures. After the pollen and the anther enter the second sieve plate, most of the smaller pollen passes through the second sieve and is screened into the arc convex plate. A small part of the pollen mixed with the anther is eccentrically shaken and shaken to the outermost ring of the inner circle of the second sieve plate together with the anther. An annular groove is provided between the second sieve plate and the second sieve, and the remaining pollen will flow into the arc convex plate through the annular groove. The anther is blocked by the block A at the discharge port and flows out from the discharge box B. When the pollen falls into the arc convex plate, it first falls into the arc surface and slowly slides to the inner outer ring of the arc convex plate. After reaching the plane, it is blocked by the block bar after shaking and rotating, and flows out after entering the discharge box A, thereby achieving the effect of layered screening.
