Abstract

In this paper, the potato excavator design research and application of the carried on the thorough introduction and analysis, designed the separation combination of potato. Design of the machine's main parameters for the selection, design of main components of the theory of mechanism, structural optimization and design calculation. Potatoes are underground, and tuber propagation, and the harvest season, weather and other objective conditions and has a lot to do. Because the potato harvest laborious time-consuming, strong seasonal and the intensity of labor is big, which cause great harvest difficult for farmers. In order to solve the above problem, in this paper, the present situation of both at home and abroad of potato, potato digger actual research and application of the introduction and analysis, cleverly designed separation combination of potato. Selection of the main parameters of the excavator, design of main components of the theoretical calculation, design a new type of potato excavator has the better performance, better adapted to the modern agriculture productivity, solve the labor productivity greatly.
