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, a combined separation potato digger has been developed through selection of principal parameters and theoretical calculation for the design of essential parts.
为了解决上述问题,设计了组合分离式马铃薯挖掘机。
