China has a sea area with a wide area, and the wide sea area can provide various marine products such as fishes, shellfishes, kelp and the like for China, wherein the kelp has a large culture area in the sea area, and can provide a large amount of kelp products. The kelp contains rich algin and iodine, and can be used for eating, medicine application and extracting various industrial raw materials such as iodine, algin and mannitol, so that the kelp has a relatively high application value.

The kelp needs to be aired, bundled, cut and the like in the cutting process, and the processes are mostly carried out manually. The kelp binding and cutting are usually performed manually, and due to different proficiency of manual operation, the binding and cutting progress is different, so that the output efficiency of the kelp is influenced. In the cutting season of the kelp, a large amount of kelp needs to be bundled and cut, and the kelp after airing is stacked together to wait for bundling and cutting. Due to the fact that season and climate change of the kelp cutting are large, rainwater is more, and if the kelp is bundled and cut out untimely, the accumulated kelp needs to be subjected to moisture-proof treatment. If the accumulated kelp is wetted or moistened, the kelp needs to be aired again, and a large amount of manpower and material resources are wasted. Even the kelp which is seriously affected with moisture can be rotten, which brings economic loss to kelp culturists. For kelp airing, fresh kelp is usually put on a beach or a kelp airing rack for airing. When the kelp is aired on the beach, the kelp is easy to stick with sandy soil and weeds, and the finished product quality of the kelp is affected, so that the airing of the kelp airing rack gradually replaces the airing of the beach. Uniformly arranging wooden piles on the ground, and tying waste fishing nets on the wooden piles in a tying mode to form the kelp airing rack for isolating the ground. The kelp airing frame is used for airing the kelp, and the kelp also needs to be manually paved one by one and turned over and aired at regular time so as to ensure even airing.

In the processes of airing, bundling, cutting and the like, each process needs a large amount of manpower, and economic loss is brought to kelp cultivators if the operation is not timely.
