Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and specifically relates to a fully hydraulic self-propelled crawler grain transport vehicle. Background Art

[0002] In the prior art, in the grain processing industry, ordinary freight trucks are used for the transportation of grain, rice, wheat, etc., and the types of freight vehicles used in the field of grain transportation are mainly flatbed semi-trailers or barn-type semi-trailers. When harvesters harvest crops such as rice, they need to quickly collect the crops into grain transport trucks, and then transport them to other large vehicles or storage areas by grain transport trucks. This requires vehicles to adapt to the soft ground of farmland. At the same time, grain can be output from grain transport trucks at high speed to ensure the mechanization of grain harvesting. The grain transportation process is to put bulk grain bags into trucks and then load, transport and unload them manually or using loading trucks. After arriving at the processing plant, they need to be manually Unloading grain, manually unpacking the bags, and then transporting it to the production line for processing will increase the cost of bags, bagging and unpacking processing costs, labor costs, etc., which consumes working hours and cannot achieve transportation automation and efficiency. In the process of grain trucks transporting grain, since grain trucks need to transport grain in fields or mountains, their operating conditions are relatively harsh. Traditional wheeled grain trucks are easily stuck in the mud and have poor passability. In addition, traditional grain trucks are only equipped with a single drive source. Since the grain truck is heavy when fully loaded and has a large ground contact pressure, it is difficult for the grain truck to get out of trouble when it gets stuck in muddy conditions, resulting in poor passability and stability of the grain truck in complex operating environments.
