The present invention provides an automatic sorting device for shellfish, which comprises a housing having an entrance and an exit; a rotary shaft formed within the housing to be rotated by a driving means formed in the exterior of the housing; multiple impellers formed on the rotary shaft at constant intervals; and multiple fixed blades projected on the inner side of the housing to be positioned between the impellers, wherein the end terminal of the wings of the impellers and the end terminal of the fixed blades are formed to become sharp, the thickness of the wings of the impellers is formed to become thinner toward outside from the center, and one side of the wings positioned in the rotary direction is a triangular cutting blade. The present invention is a useful invention, which prevents the damage of shellfish and improves the price competitiveness and the productivity by minimizing the pressure and the resistance of the impellers and the fixed blades due to shellfish when separating the shellfish attached to a cultivation rope by forming the end terminal of the wings of the impellers and the end terminal of the fixed blades to become sharp in a triangular form, and making the thickness of the wings of the impellers thinner toward outside from the center. |
