Description

Technical Field

[0001] The utility model relates to the field of tobacco leaf harvesting, and more specifically, to a small gantry crawler-type tobacco leaf harvesting and transporting platform. Background Art

[0002] Harvesting tobacco leaves is fundamental to tobacco production, and timely harvesting significantly impacts their quality. my country's tobacco-growing area is vast, and the terrain varies greatly, encompassing hills, mountains, and plains. Large tobacco harvesting machines are unable to operate in these hilly and mountainous areas, forcing manual harvesting to be the primary method. Smaller, manually assisted harvesting and transport machines, while more adaptable in the field and capable of more complete harvesting, still impose labor constraints, resulting in high labor input, high labor intensity, and relatively low harvesting efficiency. Failure to harvest tobacco leaves in a timely manner can lead to significant economic losses.
