Description

Technical Field

[0001] The utility model relates to a chassis folding device for a tobacco transport vehicle. Background Art

[0002] After the tobacco leaves are harvested in the field, they need to be moved out of the plot in time and transported to the drying room for baking and curing; the traditional method of harvesting tobacco leaves mainly relies on manual harvesting, with one hand picking the tobacco leaves and the other hand holding the tobacco leaves, and then moving them to the field after the leaves are full. Due to the high density of tobacco transplanting, the small ridge spacing and the large volume of leaves after maturity, the manual single harvesting and transportation volume is extremely limited. Tobacco farmers often need to go back and forth many times to transport the tobacco leaves picked from a ridge to the field. In order to improve the picking efficiency, the existing picking method uses manual picking and transportation with tobacco transport vehicles. However, due to the narrow ridges in the tobacco planting fields, it is very inconvenient for tobacco transport vehicles to turn around or turn, which affects the transportation efficiency.
