Description

Technical Field

[0001] The utility model relates to the technical field of potato harvesters, in particular to a drum soil-cleaning crawler potato harvester. Background Art

[0002] Potato harvesting has always been a labor-intensive process with a relatively poor working environment. With the increasing shortage of labor in recent years, the potato harvesting problem has become a bottleneck restricting the development of the potato planting industry. Since my country's potato planting is carried out in complex areas such as hilly and mountainous areas, large potato harvesters are difficult to adapt to the terrain of hilly and mountainous areas and cannot enter the fields. They have poor adaptability, and most of them first use harvesters to turn the potatoes underground onto the ground, and then use pickers to pick up the potatoes on the ground and bag them.

[0003] There are many problems with this harvesting mode. Frequent replacement of operating machinery can easily damage potatoes, reduce potato quality, and affect subsequent economic benefits. A large amount of manpower participation leads to high harvesting costs and cannot guarantee the quality of operations. Therefore, in order to solve the above problems, we need to design a drum soil-clearing crawler potato harvester. Utility Model Content
