Abstract: At present, during the mechanized harvesting of kelp, kelp is retrieved by means of conveyor belt or crane. These two methods are suitable for wild kelp and kelp cultured by single rope suspension method. It is not suitable for the harvesting of kelp cultured with raft made with parallel ropes crossed on two main parallel ropes. In order to solve the problem, based on the principle of bionics, a limiter was used to simulate the artificial clenching to limit and block the movement of the pipe rope, while an electro-hydraulic push rod and a clamp were used to simulate the extension and bending of the arm. With the rope connectors, the harvesting device could complete the harvesting of kelp without untying the crossed rope or floating ball before all kelp on one raft harvested completely. At the same time, it could remove the tips and roots of kelp in the process of harvesting with two sets of cutter, and transport the main body and the tip of kelp respectively to other boats with two conveyor belts. The device could improve the labor efficiency and reduce the labor intensity.
