Description

Technical Field

[0001] The utility model relates to the technical field of tobacco planting, in particular to a field tobacco leaf transportation device. Background Art

[0002] During the tobacco leaf harvesting process, due to the terrain restrictions of the tobacco leaf fields, large-scale machinery cannot be used for harvesting, and it can only be done manually, which greatly affects the efficiency of tobacco leaf harvesting. In addition, during the harvesting process, the tobacco leaves need to be transported out of the farmland manually, which increases the labor intensity of the workers. Not only is the workload heavy and large, but also the damage caused by manual transportation of tobacco leaves affects the quality of the later tobacco leaves. The use of mechanical transportation is the inevitable development direction to solve the problem of manual operation.

[0003] The existing patent number is 201811596846.0, which discloses an efficient semi-manual tobacco leaf picking machine that can realize manual identification of tobacco leaves, mechanical field walking, traceless lifting and storage, automatic weighing and tobacco sorting, and hanging and loading tobacco. However, the transportation volume and transportation efficiency are limited, and it is not suitable for large-scale field tobacco leaf transportation.

[0004] There is also a patent number of 202322023335.2 that discloses a traction-type tobacco leaf field transportation equipment, which uses a traction trolley to pull the tobacco leaf collection hopper to move along the ridges. It is suitable for transporting tobacco leaves in tobacco fields. It not only greatly reduces the labor intensity of manual handling of tobacco leaves, but also improves the handling efficiency and effectively avoids the problem of mechanical damage to tobacco leaves. There is a traction trolley matching a tobacco leaf collection hopper, which wastes power resources, and the transportation volume and transportation efficiency are limited. In addition, the tobacco leaf collection hopper moves slowly in the field, further reducing the transportation efficiency.

[0005] There is also a patent number 202323092430.4 that discloses a simple field fresh tobacco leaf transportation device. A driving wheel is set at the bottom of the transport vehicle body; the two sides of the driving wheel are connected to the bottom of the transport vehicle body through active wheel brackets; auxiliary support wheels A and auxiliary support wheels B are respectively set on both sides of the driving wheel; auxiliary support wheels A and auxiliary support wheels B are staggered structures set at the front and rear of the driving wheel, which can realize the convenient transportation of tobacco leaves by loading multiple tobacco leaf frames on the transport vehicle body, and conveniently move in the narrow trench cages in the tobacco field, thereby improving the transportation efficiency of tobacco leaves. However, if too many wheels are set, the tobacco field is narrow and the wheels are easily stuck, which affects the transportation efficiency. Utility Model Content
