Potato harvesting machine for hilly and mountains regions

The invention relates to a potato harvesting machine for hilly and mountains regions, and belongs to the field of agricultural harvesting machinery and equipment. An excavating device digs up soil andpotato mixtures; power is transmitted to a power transmission system through a power output shaft of a tractor, is outputted to drive shafts in a gear box to rotate, and is transmitted to a driving wheel through a chain to drive vibration separating devices to rotate; the primary vibration separating device is rotated to vibrate and separate the soil and potato mixtures which are then conveyed tothe secondary vibration separating device; potatoes with less soil are subjected to vibration separating again by the secondary vibration separating device, and then conveyed to a lateral conveying system. The potato harvesting machine has the advantages that the angle of the excavating device is adjusted through a hydraulic cylinder to achieve stepless angle adjustment; the two-stage vibration separating devices are applied to solve the problem of high soil stickiness of the hilly and mountains regions, and the separation frequency is high; the potatoes are piled up in strips through a lateral conveying device, the rate of visible potatoes is increased, and the potato burry rate and damage rate are decreased.
