Crayfish grading equipment based on wind power

The utility model discloses crayfish grading equipment based on wind power, and belongs to the technical field of sorting equipment. The crayfish sorting device solves the problems that in the prior art, crayfish are mechanically sorted, the feet of crayfish are meshed and hung on a shelf, the sorting effect is poor due to the fact that the shapes of the crayfish are not regular enough, and the cost is high in an intelligent detection and classification mode. A first conveying belt with a partition plate is arranged below the discharging end of the freezing anesthesia mechanism, a plurality of air outlets are formed in one side of the first conveying belt, a plurality of collecting frames are arranged on the other side of the first conveying belt, and the air outlets are formed in the conveying direction of the first conveying belt. The wind power of the air outlets is gradually increased from the end close to the freezing anesthesia mechanism to the end away from the freezing anesthesia mechanism, and the nu
