Then the opening and closing cylinder 14 drives the opening and closing chute 13, the opening and closing slide block 12 and the opening and closing push rod 11 to move downwards, so that the clamping jaw 2 is opened, and the seedling roots are released. The jaws are then closed and the lifting cylinder 10 drives the tube 7 upwards, retracting the jaws into the plug. The seedling rope is tensioned towards two sides, so that the kelp seedling roots are fixed on the seedling rope to finish the seedling clamping action. And finally resetting all actions and waiting for the next seedling inserting process.

Whole device compact structure can duplicate 30, and equidistance is arranged on width direction, has reduced kelp seedling storage device's occupation space. 30 rotatory eccentric seedling rope and the seedling device of pressing from both sides of floating are inserted the seedling simultaneously, have improved the work efficiency who inserts the seedling by a wide margin, have effectively solved current kelp seedling transplanting machine semi-automatic seedling transplanting speed than artifical slowly, inefficiency, the easy impaired problem of root system.
