The invention provides an elastic
cutting system for modified root-
tuber crops, and relates to the technical field of
agricultural machinery. The elastic
cutting system comprises a base and a driving device, wherein a floating plate is arranged above the base, an elastic supporting mechanism is arranged between the base and the floating plate, a first
cutting knife is arranged at the bottom end of the floating plate, and the driving end of the driving device is connected with the first cutting knife; and the edge of the first cutting knife extends out of the edge of the floating plate, a clamping conveying belt is arranged above the floating plate, and the clamping conveying belt clamps the modified root-
tuber crops to move towards the first cutting knife. According to the
system, modified
root crops can be automatically and mechanically
cut, by arranging the combination of the floating plate and the elastic supporting mechanism, the floating plate can be forced to float up and down according to different sizes of modified rhizomes, so that the first cutting knife does not
cut the modified roots while having a mechanical cutting function, the cutting loss is reduced, the cutting efficiency is improved, in addition, the
economic benefits are increased, the structure is exquisite, and the practicability is extremely high.
