[0057] During operation, when the floating ball 4 being dragged to the limiting unit, the floating ball 4 pushing a plurality of barrier strips 21 backwards under the pulling of the main rope 3, S-shaped anti-curve barrier strips 21 enclosing a depressed face, which can well prevent the floating ball 4 from sliding out of the limiting unit; when the floating ball 4 crossing, the remaining barrier strips 21 falling except that one barrier strip 21 being still lifted by the main rope 3, lifting a left and right moving range of the main rope 3, the barrier strips 21 lifted by the main rope 3 generating downward pressure to the main rope 3, so as to limit an upper and lower moving range of the main rope 3; when the seedling rope 2 being dragged to the limiting unit, the seedling rope 2 pushing the blade 22 to rotate, the seedling rope 2 coming to the gap and passing through the gap along the blade driven by the seedling rope 2, and at the same time, the blades following the seedling rope 2 blocking the gap, due to the blockage of the blade 22, the main rope 3 cannot contact with the gap, so as not to be blocked at the gap.
[0058] IIL Cutting
[0059] Under itself gravity, the seedling rope 2 and the kelp 1 thereon in the area where the rear extension guide rails 130 being located sliding to the front of the static blade 52 of the cutter; due to the supporting of the brace rods 8 and the rear extension guide rails 130, the seedling rope 2 may be suspended on the static blade 52 more flatly, with a small sag; after all seedling ropes 2 sliding to the front and rear of the static blade 52 of the cutter, starting the electromagnetic rope stopper, so that the electromagnetic rope stopper stretching out the top face of the rear extension guide rail 130; then starting the rear electro-hydraulic push rod 140, so that the rear extension guide rail 130 lifting to the suitable position (taking the rear extension guide rails 130 lifting to be horizontal as an example, if the length of the kelp located between the upper and lower cutters is less than the required length at this time, it may be solved by two methods: first, continuing to lift the rear extension guide rail 130, due to the existence of the electromagnetic rope stopper, the seedling rope 2 and the kelp 1 thereon will not slide too much distance forwards, and during cutting, the kelp 1 will be pushed to the static blade 52 by the moving blade 54 of the upper cutter for cutting; and second, keeping the rear extension guide rails 130 be horizontal, and starting the roller conveyors 40 so as to convey a section of kelp backwards). Afterwards, the lower cutter and the upper cutter being started successively to cut the kelp;
[0060] When not working:
[0061] 1) Closing the dragging unit, roller conveyors and the cutting unit for resetting;
[0062] 2) Opening the discharge bolt at the bottom of the container, to flush the harvesting device;
[0063] 3) Flattening the reversible baffle;
[0064] 4) Lifting the front extension guide rail 13 to the horizontal position, supporting the front wall of the container, locking the front electro-hydraulic push rod 14, at this time, the elastic pillars 6 recovering the original position to be as high as the discontinuous handrail 5, so as to play a handrail role and ensure the personnel safety, then recovering the front horizontal extension arm 12, and unlocking the inhaul cables 9 from the front horizontal extension arm 12;
[0065] 5) Retracting the front extension guide rails 13, unlocking the front electro- hydraulic push rod 14, placing the front extension guide rails 13 to the original position, unlocking the inhaul cables 9 from the front extension guide rail 13, and locking the front wall;
[0066] 6) Lifting the rear extension guide rail 130 to the horizontal position, supporting the rear wall of the container, locking the rear electro-hydraulic push rod 140, and taking back the rear horizontal extension arm 120;
[0067] 7) Retracting the rear extension guide rails 130, unlocking the rear electro- hydraulic push rod 140, placing the rear extension guide rails 130 to the original position, and unlocking the rear wall of the container;
[0068] 8) Screwing the discharge bolts, walking out of the container 60, and locking the doors on the front and rear doors.
[0069] 9) Unlocking the container 60 from the container anchors, lifting away the vessel, lifting the vessel on a vehicle to be transported to other places for storage or shipped in other places.
[0070] The above is the preferred embodiment of the present disclosure, those of ordinary skill in the art may make various changes or improvements on this basis, and these changes or improvements shall belong to the scope requested by the present disclosure without departing from the overall concept of the present disclosure.
