The invention relates to the technical field of
agricultural machinery, and discloses a pull-type
ridge-imitating sweet potato
seedling vine harvester and a method, the pull-type
ridge-imitating sweet potato
seedling vine harvester comprises a harvester shell, a
seedling picking and
cutting mechanism, a chopping mechanism, an
auger mechanism and a throwing and blowing fan are sequentially arranged in the harvester shell, the seedling picking and
cutting mechanism is used for picking seedlings and
cutting the seedlings simultaneously, and the chopping mechanism is used for chopping the seedlings; broken seedling vines enter the
auger mechanism after being crushed by the chopping mechanism, and then are conveyed to the throwing fan; the seedling picking and cutting mechanism is in
butt joint with the front side of the chopping mechanism and comprises a seedling picking shaft, the height of the seedling picking shaft is matched with the height of
ridge backs, disc cutters are arranged at the positions, close to the two ends, of the seedling picking shaft, and seedling picking rods are arranged on the inner sides of the disc cutters so as to pick creeping seedling vines in furrows or between ridges to the chopping mechanism; the
disc cutter is arranged to
cut off twined seedling vines at furrows, so that the situation that the seedling vines cannot be picked into the chopping mechanism by the seedling picking rod due to twining is prevented, and it is guaranteed that the seedling vines at the positions where the harvester passes can be picked up, chopped and then collected.
