Design of Potato Excavator
Abstract: Potato is an under ground plant. Its harvest is limited by the crown of the year and weather. Since the potato harvesting process has some difficult problems for farmers such as being strenuous and time consuming, great in labor intensity and urgent in seasonal demand, the paper analyses the present situation of potato harvest, and a combined separation potato digger has been developed through selection of principal parameters and theoretical calculation for the design of essential parts.
