[0002] At present, the areas where my country's coal resources are relatively concentrated are all in areas with severe winter cold. Due to the specific processing procedures of coal mine preparation plants, coal materials need to be washed and stored in coal bunkers before being discharged and loaded onto trucks for transportation to export areas. Among them, the loading gate is used as a material separation gate for loading coal out of coal bunkers, and it is widely used.

[0003] Most of the existing loading gates do not have cold-proof structures. After coal washing, the coal often contains a large amount of moisture. When the outside temperature is low, the coal is easily frozen, thus affecting the normal opening and closing of the gates. The gates can only be opened after the staff have de-iced them on site, which requires a lot of waiting time and easily affects the efficiency of coal loading.
