Background technique

Tobacco is an important economic crop. At present, tobacco planting in my country is mainly concentrated in the vast rural areas. Tobacco farmers engaged in small-scale tobacco planting account for a large proportion. After the tobacco leaves are cured and before delivery, the tobacco leaves are in a fluffy state. In order to reduce the storage space, the tobacco leaves need to be compressed. At the same time, the tobacco leaves also need to be compressed and packaged for the convenience of transportation when they are sold. However, most of the currently used tobacco leaf packaging equipment is concentrated in the tobacco leaf purchasing station, and its power source mostly adopts a hydraulic system, which not only has a high cost of use, but also easily leaks hydraulic oil to cause contamination of the tobacco leaves. In addition, these equipment are complex in structure and expensive. The average tobacco farmer cannot afford it. If the tobacco farmers transport the tobacco leaves to the purchase station for packaging at the time of sale, it is often difficult to transport and bring a lot of inconvenience to the tobacco farmers; if they rely on manual packaging, it is time-consuming and laborious, resulting in inconsistent packaging specifications and even damage to the tobacco leaves, which is not only inconvenient Tobacco leaves are stored and placed at the purchasing station, and the damage to the tobacco leaves will lead to a reduction in the grade of the tobacco leaves, which will bring unnecessary losses to the tobacco farmers to a certain extent.
