Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production tools, in particular to a device for flue-curing tobacco on and off a heatable bed. Background Art

[0002] During tobacco cultivation and processing, curing is a critical step in ensuring tobacco leaf quality. During the curing season, tobacco leaves are loaded into the curing barn for drying and unloaded after drying. This process is often referred to as "going up and down the kang." While seemingly simple, it actually presents numerous challenges.

[0003] First, tobacco farmers typically have to manually move the leaves up and down the kang, especially when placing them on the second floor of the flue-curing barn or above. This requires them to climb to a higher level to handle the work. This method not only increases the risk but also places high demands on the workers' physical strength. This is especially true for older farmers, who face greater risks and a higher probability of accidents during the process. Second, the traditional method of moving the leaves up and down the kang lacks effective auxiliary tools, making them susceptible to mechanical damage during handling. This damage can reduce the quality of the leaves, thereby affecting the value of the final product and resulting in additional economic losses for the farmers. Utility Model Content
