Description

Technical Field

[0001] The utility model relates to the technical field of road snow removal equipment, in particular to a salt spreading vehicle. Background Art

[0002] Snowfall often occurs in winter in northern my country, which can easily cause snow on the road. If the snow on the road is not cleared in time, accidents are likely to occur, which will have a serious impact on people's travel. In order to ensure road driving safety, municipal departments usually spread snow-melting salt after mechanical snow removal on the main roads of the city to prevent the roads from icing. For non-main roads, personnel are organized to use simple snow removal tools to carry out snow removal operations, and then use manual salting to melt the snow on the road surface. There are a large number of road snow removal workers, high labor intensity, slow progress of snow removal operations, a large amount of manpower and material resources, high labor costs, and uneven manual salting, which will result in a low utilization rate of snow-melting salt and serious waste.
