In the mechanical harvesting process of the whole sugarcane, the sugarcane is cut off and held down, the sugarcane is fed into a leaf peeling device to peel off leaves, and then the leaf peeling device finishes the leaf peeling and collecting transportation process, so that the workload of the leaf peeling device is the largest. In practical operation, a plurality of sugarcanes are generally gathered and fed into a leaf peeling device for peeling leaves, so that the stripping and separation of the sugarcane leaves wound and extruded on a sugarcane stalk are very difficult, even if the leaf peeling strength of a leaf peeling element is improved, the sugarcane leaves are difficult to be completely separated from the sugarcane stalk, and the sugarcane is very easy to damage.
