At present, the domestic scallop shelling and meat extraction are still mainly done by hand, and the processing environment is harsh and the production efficiency is low. In order to improve this situation, an artificial peeling machine for bay scallops is designed. It is based on the principle of manual cutter peeling off the shells, using elastic blades, and the blades to fit the scallop curved surface to peel off the adductor muscle is pushed by the cylinder. The roulette layout is adopted, it is mainly composed of shell cutting components and adductor muscle components. The measurement data was analyzed by MATLAB, the position of the adductor muscle and the cutting position of the shell cutting device are 8 mm away from the edge of the shell. The scallop shell body was curve-fitted by Origin to establish a geometric model of the scallop inner shell. The size of the scallop muscle peeling blade b=20 mm wide l=114 mm long, the average opening angle of the scallop β=27˚, and the bending angle range α=2˚~5˚. Simulation analysis with Adams. The test results show that the success rate of the bay scallop shelling machine is over 85%, and the shelling efficiency is 20 pieces/min. The shelling machine meets the requirements of scallop processing quality and production efficiency.
