The invention discloses a beating device for removing attachments on a scallop culture cage and mainly solves the problems that the labor intensity of workers is large and the removal efficiency is low due to the fact that attachments on a culture cage are removed through manual beating currently. The beating device comprises a support and two supporting bases assembled on the support, wherein a rotary shaft provided with a driving wheel at one end is rotationally supported on the two supporting bases, a driving part is arranged on the rotary shaft, the far end of the driving part is connected with a fixing plate through a connection assembly, and a plurality of beating belts are arranged on the fixing plate. The driving wheel is driven by a motor to drive the rotary shaft and the driving part to rotate synchronously and to drive the beating belts on the fixing plate to shake and beat the attachments on the scallop culture cage by means of the connection assembly, the labor intensity of workers is small, and the beating device is reliable to use and high in removal efficiency.
