Description

technical field

[0001] The invention relates to the technical field of equipment capable of one-time combined potato harvesting, in particular to a graded potato combined harvester. Background technique

[0002] At present, there are basically two types of potato harvesting machines at home and abroad: one is a small and medium-sized potato excavator, which has a single function. It can only dig, separate, and lay potatoes on the ground in strips, and then pick them up manually. It is labor-consuming and time-consuming, the production efficiency is low, and the labor intensity is still relatively large. One is a large and medium-sized potato combine harvester, which also has a self-storage type and a side-arm output type. The side-arm output type is more commonly used. It is bulky and has a large supporting power. 1. It is difficult to work on the edge of the field, and it is suitable for large-scale operations. At present, there are patent reports on the potato combine har...
