Abstract: iming at solving the problems of potato damage during the mechanization of harvesting, cleaning, sorting storage, and grading, this article summarized and analyzed the multiple injury factors, such as mechanical working parts, farmland soil conditions, potato planting habits, etc. and pointed out problems needed to be solved. The paper thought some new anti-damage material and high frequency low amplitude vibration separation technology should be used in potato harvesting. The paper also discussed the theory of soil cutting and pressing, optimized and added the device to reduce the damage, and analyzed the mechanical properties of potato by combining the elastoplastic theory and contacting mechanics model. It was of important significance to develop and improve the warehousing equipment for potato harvesting, cleaning and grading. Based on these, the paper put forward suggestions and measures to further enhance the control ability of damage simulation and detection in various production processes, so as to realize the integrated control of broken peel in mechanization production and reduce mechanical damage. Thus, the paper provided useful reference for achieving low damage harvest and fine chemical cleaning and grading.
