Shellfish cleaning and grading device

The utility model provides a shellfish cleaning and grading device which comprises a machine frame, a vibrating screen plate, a flow guide disc and a grading mechanism are sequentially arranged on the machine frame in the shellfish conveying direction, a spraying pipe is arranged above the vibrating screen plate, and the grading mechanism comprises at least one pair of conical spiral rollers and a driving device for driving the conical spiral rollers to rotate. The position where the conical spiral roller is located is lower than the position where the flow guide disc is located, the diameter of the conical spiral roller is gradually reduced from the end close to the flow guide disc to the other end, and a plurality of collecting hoppers arranged in the axial direction of the conical spiral roller are arranged below the conical spiral roller. Therefore, the manual labor intensity and the production cost are reduced. 本实用新型提供一种贝类清洗分级装置，包括机架，机架上沿贝类的输送方向依次设有振动筛板、导流盘和分级机构，振动筛板的上方设有喷淋管，分级机构包括至少一对锥形螺旋辊以及驱动锥形螺旋辊转动的驱动
