Description

Technical Field

[0001] The utility model relates to the technical field of tobacco field transportation devices, in particular to a stacked and telescopic tobacco bin device for tobacco leaf harvesting machinery. Background Art

[0002] The tobacco barn is an important part of the tobacco fresh leaf harvesting machinery and is a device for carrying the harvested fresh tobacco leaves. The reasonable design of the tobacco barn is an important indicator for improving the working efficiency and quality of the tobacco leaf harvesting machinery. At present, the tobacco barns of all tobacco leaf harvesting machinery are designed with a fixed length structure, which results in the same number of tobacco leaves carried by the tobacco barn at a time when the external shape of the tobacco machinery remains unchanged, resulting in the same turning radius of the harvesting machinery when turning around at the end of the field.

[0003] The prior art discloses a patent with the announcement number CN219087840U, which includes a crawler walking base, a support platform is provided on the crawler walking base for vertical lifting, and a tobacco leaf storage is provided on the support platform for sliding along the moving direction of the vehicle body. The utility model solves the problem that the traditional technology overcomes the small application range of large tobacco leaf harvesting and transportation machinery, which is not conducive to large-scale promotion.

[0004] The existing technologies including the above patents have gradually exposed their shortcomings as they are used:

When working in the tobacco field, interference is prone to occur, which affects the efficiency of tobacco leaf harvesting.
