[0003] In the prior art, as the water content in the coal increases and the temperature drops, the freezing strength between the coal and the vehicle body increases. Once the vehicle freezes, the dump truck cannot unload the coal normally and must be cleaned manually, which often takes several hours to unload. On the one hand, the long-term occupation of the unloading space will inevitably affect the normal unloading of other vehicles and the efficiency of normal coal entering the factory when there are many vehicles. On the other hand, manual cleaning is labor-intensive. At present, the problem of frozen coal is solved by spraying antifreeze, which will increase the transportation cost, and adding too much antifreeze will affect the composition of the coal entering the furnace; there are also loaders to assist in unloading, which is no problem in unloading, but it is impossible to achieve self-unloading of coal. There is no more effective solution at present.
