Description

Technical Field

[0001] This invention relates to cabbage processing and transportation equipment, specifically to a multi-unit crate loading device for cabbage leaf removal and its control method. Background Technology

[0002] Chinese cabbage, as an important vegetable, is loved by the people. In China, the harvesting of Chinese cabbage is mainly done by workers manually picking it in the fields, packing it into baskets, and then transporting the baskets to warehouses. This method is inefficient and places a heavy burden on workers. CN110063124A discloses a Chinese cabbage harvester, which has a certain effect on removing outer leaves. However, the passageway through which the Chinese cabbage passes is not effectively restricted. After the outer leaves are removed, the cabbage is not arranged in an orderly manner, nor is it diverted or organized, making it inconvenient for subsequent orderly packing. The efficiency of leaf removal and packing is low. Furthermore, the packing step of this invention involves the Chinese cabbage falling directly into a large box for packing, which easily leads to a large amount of wasted space due to the disorderly packing of columnar cabbage.
