This machine is a research and development achievement of the national sweet potato industry technology system. In order to improve the efficiency of dehulling operations, it is equipped with a high horsepower tractor suspension system and uses free state crushing knives of different lengths to simulate a double ridge arrangement for high-speed rotation and dehulling of vines and seedlings; On both sides, shoe shaped seedling picking knives and long vine cutting knives are used in combination to crush the long vines in the ridges and valleys, which is beneficial for removing the vines in the ridges and valleys; Adopting multi-point independent floating support to limit depth, reducing the impact of unstable tractor movement on operations, and achieving smooth de creeping operations on complex ground; The use of a digging plow with adjustable digging depth and soil entry angle results in low resistance before harvesting, improving the operational performance in the sticky and heavy soil area of the plain dam.

Application field: Suitable for vine planting before sweet potato excavation in plain dam areas or hilly and gentle slopes.
