Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf processing, in particular to a tobacco leaf bone breaking machine. Background Art

[0002] Among tobacco varieties grown, sun-cured tobacco is one. During the curing process before the tobacco leaves are harvested, sun-cured tobacco differs from flue-cured tobacco. Flue-cured tobacco undergoes the yellowing, coloring, and stalk drying processes in artificial curing barns, while sun-cured tobacco is dried in the sun under natural conditions, completing these three steps according to specific technical requirements and experience. Because the veins of sun-cured tobacco leaves are thick, especially at the petiole end, a tobacco leaf debrider is used to pierce the main veins of the leaves to a certain depth before drying. This allows for rapid evaporation of moisture from the fresh leaves, meeting curing requirements and accelerating the curing process.

[0003] However, when using the existing tobacco leaf bone crusher, due to the different thicknesses of the veins of different tobacco leaves, the veins need to be cut to different depths, making it difficult for personnel to adjust according to needs, resulting in inconvenience for personnel and affecting the processing efficiency of tobacco leaves.
