BACKGROUND

[0002] Chinese patent No. 111512774A filed on August 11, 2020 discloses “Bionic

Kelp Harvesting Device and Harvesting Method”, which are used for harvesting kelp in raft aquaculture. The device still exists four problems: first, the fixation of a rack and a guide rail causes that a pulling angle of a main rope is fixed, so the pulling angle cannot be adjusted in time along the change of ebb and flow, affecting the kelp harvesting; second, the fixed rack and a fixed knife rest are hard to adapt to cut the kelp of different lengths (the kelp is usually 3-6 m long, and a kelp tip, accounting for 1/3 of the length is usually cut); third, exposed to the sea for a long time and exposed to the sun and rain, equipment is hard to maintain, and the service life 1s reduced; and fourth, only three months in each year are used for kelp harvesting, the device is fixedly mounted on a vessel, with a great land occupation and hard disassembly, so the vessel is difficult to be used as other purposes during a non-kelp harvesting period, resulting in a low vessel utilization rate and poor economy.

SUMMARY

[0003] The present disclosure aims at providing a kelp harvesting device equipped extension rods with chains and covered by a container and a harvesting method thereof, so as to process rack angle adjustability and be convenient to adjust a pulling angle in time along the change of ebb and flow. The cooperation of an adjustable rack and a movable cutting knife is conductive to cutting the kelp of different lengths; split limiters enable floating balls to be contained by limiters, floating ball ropes will not be wound on vertical rods of the limiters, so as to pass through the limiters more easily. An extension rod and a plug-in rod are used in cooperation with the rack, so that the device may be used on a vessel with different freeboards (the vertical height from the water surface to the main deck of the vessel is called the freeboard, that is, the difference between the moulded depth and the draught of the vessel). The whole device is contained in a container, so that the device has a plug-and-play flexibility, and the utilization rate and economy of the vessel are improved. Compared with a situation that the device is exposed the open air, the container plays a role in protecting the device, so the service life is prolonged. Contained in the container, the device is convenient for land transportation, so that the device owner can realize the trans-regional operation by using the time difference of the kelp maturity stages in different areas, thereby improving the utilization rate and economy of the device.
