The harvesting mode has larger energy consumption due to larger machine type. The other method adopts various small potato combine harvesters to harvest. The simplest small-sized potato combine harvester is only provided with a primary common bar conveying sieve device (the conveying sieve does not vibrate), excavated potatoes are only simply sieved on the conveying sieve which runs straightly and directly fall on the ground, and the potatoes are manually picked up. The harvesting mode consumes manpower and has low working efficiency.
In order to improve the harvesting efficiency of the small potato combine harvester, a one-stage or two-stage conveying device is additionally arranged behind a one-stage conveying and separating device behind an excavating device of the harvester, and a hopper for collecting potatoes is additionally arranged behind a final-stage conveying device. In order to improve the separation effect of the primary conveying and separating device of the small potato combine harvester, an eccentric wheel capable of driving the bar conveying device to move up and down in a wave manner is generally arranged at the central part of the bar conveying device, so that potato soil mixture conveyed by the digging decoration rolls back and forth on the bar conveying device to accelerate the crushing of soil blocks and the separation of potatoes, soil and roots. The one-stage conveying and separating device has the advantages that firstly, the potato-soil mixture is low in rolling frequency along with the wave motion of the rod conveying device, soil blocks are not broken thoroughly, and part of small uncrushed soil blocks are conveyed to the next-stage conveying and separating device along with the operation of the rod conveying device, so that the potato-soil separating effect of the one-stage conveying and separating device is reduced, and the burden of the next-stage conveying and separating device is increased; secondly, when potatoes separated from soil roll back and forth on the bar conveying device in the advancing process, the potatoes collide with each other, so that the potato peeling damage is caused, and the quality and the market price of the harvested potatoes are influenced.
In addition, the potatoes separated by the first-stage conveying and separating device are inevitably carried with a small amount of small soil blocks and are conveyed to the next-stage conveying device with the main conveying function, and finally the potatoes are output together with the potatoes due to the fact that the small soil blocks cannot be effectively removed, and the quality of the harvested potatoes is affected.
