This invention provides an ejector device for shellfish harvesting, belonging to the technical field of shellfish harvesting devices. It solves the technical problem of low shellfish suction efficiency in existing ejector devices. This jet device includes an inlet pipe and an outlet pipe, which are linearly and fixedly connected by an expansion pipe. A suction tube is fixedly connected to the side wall of the expansion pipe, with one end extending outside the expansion pipe and the other end inside the expansion pipe and extending towards the outlet pipe. A spiral plate is fixedly connected between the suction tube and the outlet pipe. Gas enters between the suction tube and the outlet pipe from the expansion pipe, where the flow velocity and pressure increase. The gas then passes through a spiral channel formed by the spiral plate, improving flow efficiency. After entering the outlet pipe at the end away from the horizontal pipe, the flow velocity slows down, and the pressure increases. The end of the suction tube inside the outlet pipe creates a vacuum, sucking up the mixture of mud, water, and shells, reducing damage to the shellfish and improving harvesting efficiency.
