China ranks first in the world in terms of planting area and yield. However, there are still many problems to be solved in the post-harvest grading of potatoes, including the low level of grading mechanization. , high labor intensity and high grading cost, and preliminary grading of potatoes in the field can effectively reduce the subsequent workload and ensure the quality of potatoes.

国外马铃薯多在地势平坦的大型农场种植，可使用大型联合收获机，直接运输到工厂进行后续分级等工作，中间过程衔接紧密，等待时间短，效率高，但国内马铃薯的不少产区在丘陵山区等地势复杂的地区，无法使用大中型机械，需要使用不同机械轮番作业。目前国内通常将大小混杂的马铃薯一起转运至工厂内再进行分级，分级效率低，多次转运还易导致马铃薯相互碰撞，直接影响马铃薯的品质，甚至造成不可逆的损伤，而且工厂内的这些马铃薯分级机构体型偏大，流程复杂冗长，也不适合田间作业。Foreign potatoes are mostly planted on large farms with flat terrain. Large combine harvesters can be used to directly transport them to the factory for subsequent grading and other work. The intermediate process is closely connected, the waiting time is short, and the efficiency is high. However, many domestic potato producing areas are located in hilly areas. In areas with complex terrain such as mountainous areas, large and medium-sized machinery cannot be used, and different machinery needs to be used in turn. At present, potatoes of mixed sizes are usually transported to the factory for grading in China. The grading efficiency is low, and multiple transfers can easily cause the potatoes to collide with each other, which directly affects the quality of the potatoes and even causes irreversible damage. Moreover, these potatoes in the factory are graded. The size of the mechanism is too large, the process is complicated and lengthy, and it is not suitable for field operations.
