Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a crawler self-propelled potato combine harvester. Background Art

[0002] With the progress of agricultural science and technology, mechanization has been achieved in many agricultural harvesting operations, and some have even realized automation or artificial intelligence. However, only mechanization has been achieved in potato harvesting, and some harvesting machines are even very bulky. Potatoes are a special vegetable variety with a short harvesting time. Potatoes planted professionally in large quantities must be harvested within a short period of time, and appropriate harvesting tools are required. The vast majority of current potato harvesting machines are trailer-type. The tractor travels in the front, first compressing the ridges, making it difficult for the rear part to shovel soil, wasting the power of the tractor. Secondly, due to the traction-type machine, with the front vehicle plus the rear vehicle, the trailer makes the vehicle body very long, inconvenient to turn, and a large amount of land at the head and end of the field is wasted, making the operation difficult. Most of the trailer-type machines are relatively bulky. Summary of the Invention
