The invention relates to a shrimp-crab meat collecting method and meat collecting equipment. The shrimp-crab meat collecting method comprises the following steps of adding water to shrimps and crabs, carrying out extrusion crushing, and removing shells. The shrimp-crab meat collecting method is characterized in that the extrusion crushing process is finished by virtue of an extrusion device, wherein the extrusion device comprises a material hopper, a grinding wheel set, a shell discharging hole, a meat storing bucket and an electric motor, the shrimps and crabs are fed into slits of the grinding wheel set, the grinding wheel set is driven by the electric motor to extrude the shrimps and crabs so as to separate meat from shells, the shells enter the shell discharging hole, and the meat enters the meat storing bucket; the shells are removed by virtue of shell-meat separation equipment, wherein the shell-meat separation equipment comprises a vibrating mechanism, an outer bucket and an inner bucket, sieving holes are formed in the inner bucket, the inner bucket is arranged in the outer bucket, in a use process of the shell-meat separation equipment, the extruded shrimp meat and crab meat are put in the inner bucket, a high-speed motor is started, and the inner bucket is vibrated by a cam and a spring commonly, so that the shrimp meat, the crab meat and the fine shrimp and crab shells enter the outer bucket through the sieving holes in the inner bucket.
