In order to solve the problems of great labor intensity,low working efficiency,etc.in the process ofkelp seedling clamping operation,a new type of kelp seedling clamping machine was designed,with the aims toautomation of the process of seedling and rope buckle breaking,clamping of post-transplanting seedling andrestoration of seedling and rope,etc..This paper introduces the mechanical structure,the technics and workingprinciple of the machine.And post-insertation executive structure was also designed.The kinematical simulationanalysis of operation process was performed by applying the stimulation software.The results showed that theideal feeding length of seedling and rope buckle breaking was 60-80 mm; torque of rope clip and seedlingclamping rope should be less than 4.2 N·m; when the buckle was broken,the larger the torsion angle is,thelarger diameter of the rope is; adopting the clamping of post-transplanting seedlings could increase the survivalrate of post-insertion seedlings and reduce the rate of damage to the seedlings.The design of a new type ofmechanical system of kelp seedling clamping can provide references for the development and application of theplanting device of marine plants.
