Potato harvester

The invention provides a potato harvester, comprising a rack part, a hanging part to a tractor, a universal transmission device, an eccentric transmission mechanism, a vibration mechanism, a digging shovel, a conveying device, walking wheels and a tail adjusting device. The universal transmission device transmits power to the eccentric transmission mechanism, and the eccentric transmission mechanism drives the vibration mechanism to do circular motion; the vibration mechanism drives the digging shovel and a conveyor chain to swing up, down, left and right, thereby realizing the potato diggingand vibrating mud screening. 本发明提供了一种薯类收获机包括机架部分、与拖拉机挂机部分，万象传动装置，偏心传动机构、振动机构，挖掘铲、输送装置、行走轮，尾部调节装置。万向传动装置将动力输给偏心传动机构，偏心传动机构带动振动机构作圆周运动，振动机构带动挖掘铲与输送链作上下左右的摆动，实现挖署与振动筛泥。
