Description
Technical Field
The invention relates to the technical field of kelp mechanized harvesting, in particular to a kelp mechanized harvesting boat and a kelp mechanized harvesting method.
Background
China is the world with the highest yield of kelp, mature fresh kelp is easy to rot under the condition of high temperature, the quality and the yield of the kelp are greatly reduced if the kelp is harvested in time, and the kelp is harvested in China mainly in a manual mode, so that the labor productivity is low, and the labor intensity is high. With the increasing aging of population and the changing employment concept of young people, the increasing high-intensity operation labor cost year by year provides a serious test for the industry, and the kelp culture industry in China urgently needs mechanization.
At present, almost all of the kelp breeding uses a sheet-type kelp breeding method as shown in fig. 1: the kelp raft frames 31 are fixed by the raft frame fixing piles 33, the ropes 31 float on the water surface by the floating balls 8, the seedling ropes 34 are hung between two adjacent ropes 31, and kelp 7 grows on the seedling ropes 34. According to the cultivation method, higher yield can be obtained, but due to the fact that a plurality of fasteners are used for connection in the mode, the mechanical reaping boat can be prevented from entering the kelp cultivation area for reaping through more fasteners and connection modes like a net, the mutual entanglement probability of the rope and the machinery is increased, and in a region with larger storms, if the boom rope and the seedling rope are dragged out of the water surface for mechanical operation, the boom rope and the seedling rope can be greatly born due to the fact that kelp is heavy, and the reaping boat can easily twist off the rope.
With the increase of labor cost, the cultivation mode can obtain higher yield, but the cultivation benefit is greatly compressed by the increase of the labor cost of harvesting the kelp. In the earlier stage, a culture mode for culturing the kelp on the boom rope is designed, and a harvesting mode is designed for the culture mode, so that the mode for culturing the kelp on the boom rope is probably more suitable for the kelp culture mechanized operation in a sea area with large surge, but the sea surface utilization rate of the culture mode is only about equal to 1/4 in the traditional mode, so that the technical scheme balances the difficulties in the sea surface utilization rate and the kelp mechanized harvesting operation, designs the culture mode with higher sea surface utilization rate, and designs a mechanized harvesting ship and a harvesting method for the culture mode.
