Kelp harvesting and sorting method and robot

The invention relates to a kelp harvesting and sorting method. In the method, a plurality of parallel floating ropes with floats are arranged, lifting ropes are hung on the floating ropes at certain intervals, and each lifting rope is composed of an upper lifting rope segment and a lower lifting rope segment which are connected through a detachable rope fastener; the lower lifting rope segments oncorresponding portions of the adjacent floating ropes are connected through cultivating ropes, kelp is hung on the cultivating ropes, and the adjacent cultivating ropes are connected end to end intoa whole through connecting ropes; a kelp harvesting and sorting robot walks between the adjacent floating ropes, the floating ropes penetrate through screw propulsion steppers on both sides of the kelp harvesting and sorting robot, unfastening devices on the kelp harvesting and sorting robot loosen the rope fasteners one by one to make the cultivating ropes and the kelp on the cultivating ropes fall onto a kelp sorting machine, a lifting mechanism lifts the cultivating ropes and the kelp on the cultivating ropes and rotates to a kelp stacking area of a transport ship on one side, and the kelpcultivating ropes are wound around chain hooks on the kelp sorting machine and fall into the kelp stacking area.
