Technical Field

The invention relates to a fresh tobacco leaf carrying tool, in particular to a pure electric double-drive field fresh tobacco leaf carrying vehicle.

Background

The fresh tobacco leaves are transported in most tobacco leaf planting fields by manual clamping, bundling and clamping, mutual extrusion and friction among the fresh tobacco leaves are inevitably caused in the manual transporting process, so that green marks are generated, black brown spots and scratches are left after the tobacco leaves are baked, and the quality of flue-cured tobacco is directly influenced; at the same time, labor and time costs are high. Furthermore, in the case where a large amount of tobacco leaves needs to be carried, manual carrying is difficult to satisfy, so that an optimal harvesting time is easily missed. Although a small amount of wheel type carriers are researched and developed at present, the carrying efficiency is improved, the tobacco leaf carrying vehicles are large in size, complex in structure and mainly driven by fuel oil, and are mainly suitable for plain areas and have the hidden danger of soil pollution caused by waste oil discharge in fields. And to hills and mountains area characteristic landform, the sloping field is big, and the fragmentary irregular landmass is many, and big-and-middle-sized tobacco leaf transport then no longer possesses the practicality.
