Technical Field
[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a portable trolley for tobacco leaf harvesting. Background Technology
[0002] Tobacco leaf harvesting and curing are crucial steps in flue-cured tobacco production, especially the picking process. The quality of the harvest determines the quality of the tobacco leaves, which in turn affects the quality and selling price of the flue-cured tobacco. Currently, tobacco leaf harvesting is generally done manually. Tobacco is mostly grown on raised beds. When the leaves reach maturity, farmers pick and transport the mature leaves along the passageways between adjacent rows. During this process, many leaves that have not yet reached maturity need to be retained. However, the passageways are narrow, and to avoid damaging the retained leaves, it is not easy to use appropriate transport equipment. Therefore, the harvested leaves must be bundled together and carried out of the passageways manually, which is labor-intensive, time-consuming, and labor-intensive. Although there are some automatic tobacco leaf harvesting machines on the market, most of them are complex in structure and expensive, making them unaffordable for many farmers in impoverished areas. Furthermore, automatic tobacco leaf harvesting machines cannot effectively distinguish between mature leaves, resulting in poor quality flue-cured tobacco.
[0003] To address the aforementioned issues, existing patent (CN217389440U) discloses a portable trolley for tobacco leaf harvesting. It includes a wheel frame, front and rear wheels on the frame, and a balance wheel on one side of each wheel.
