Background
The traditional kelp cultivation process can be simply summarized into seedling frame and seedling curtain manufacturing, indoor seedling collection, indoor seedling cultivation, temporary cultivation in sea, seedling clamping, sea area planting, sea area cultivation and kelp harvesting.
As shown in fig. 1, in the conventional sea planting method, two ends of a seedling rope 2 attached to/holding a kelp seedling 1 are tied to two parallel floating raft ropes 3 for cultivation, and because the ropes 3 are difficult and time-consuming to install, the ropes 3 need to be installed in the sea in advance through a peg rope 9 and a wood peg 10, and then a worker ties one seedling rope attached to/holding a kelp seedling to two parallel ropes in the sea. The working environment for the operation in the sea is poor, and the problem of unstable operation caused by stormy waves must be tolerated under the condition of insolation by the sun, so that the working time and the injury probability of workers are greatly increased.
The existing kelp harvesting mode is to release the seedling ropes from the ropes one by a manual mode after the kelp is ripe, and then drag the seedling ropes into the sampan ship one by one. The weight of the kelp on each seedling rope reaches hundreds of jin, and a single repeated operation needs to consume a great deal of labor.
At present, a mechanized kelp harvesting mode is adopted, and a rope and a seedling rope are towed into a ship together. However, the length of the rope is about 75 meters, and a large number of floating balls are arranged on the rope, so that the whole rope is towed into the ship, and the weight and the volume are increased, thereby greatly increasing the harvesting difficulty.
