[0001] The invention relates to the technical field of rail-road dual-purpose vehicles, and in particular to a rail-road dual-purpose vehicle suitable for mountainous areas. Background Art

[0002] At present, farmers in mountainous areas have no good means of transportation when farming, and basically still use manual carrying, lifting and back transportation. When harvesting crops, there is no good transportation machinery to reduce a large amount of manpower and reduce the burden on workers. Since tricycles or four-wheeled vehicles cannot pass through the fields, it is difficult to use vehicles to transport crops from the fields back home or to transport pesticides, fertilizers, etc. from home to the fields.

[0003] Road-rail dual-purpose vehicles refer to the same vehicle that can be driven on both roads and rails, and are suitable for farmland transportation. Currently, the existing single-track rail vehicles on the market can only be driven on rails, which is inconvenient to branch, and most of them require secondary transportation, have a low safety factor, cannot carry people, and farmers need to walk to work in the fields, which does not solve the original farming model. Summary of the invention

[0004] In view of the above-mentioned deficiencies, the object of the present invention is to provide a rail-road dual-purpose vehicle suitable for mountainous areas, which can travel on roads and on rails, is convenient for transporting goods to farmland, can be flexibly branched, does not require secondary transfer during transportation, can carry people and goods at the same time, has a high safety factor, reduces the labor intensity of workers, and improves work efficiency.
