Background

The aforementioned snow blowing device may also be called a "snow blowing and melting device" (the same applies hereinafter), and as is known, in snowfall days, if the snow on airport roads, particularly airplane take-off and landing runways, cannot be removed in time, the normal take-off and landing of airplanes can be influenced without any doubt and safety hazards are accompanied. Therefore, the snow remover becomes an indispensable necessary facility for an airport.

Snow removal forms of airport snow sweeper mainly have two kinds: the broom is used for removing snow, and particularly, the broom is used for removing snow on airport roads and airplane lifting runways, such as CN201520951U (a front wheel drive middle snow-sweeping type airport snow sweeper), CN202705979U (an airport and highway snow sweeper), CN103362097A (a multifunctional snow sweeper) and CN204163041U (an airport snow sweeper), and the like; secondly, snow on airport roads and airplane lifting runways is blown away and melted by using high-temperature airflow sprayed by an engine arranged on the snow sweeper as a snow removing medium, the snow removing mode is also called blowing, and typical examples are a jet-propelled airport pavement snow sweeper recommended by Chinese patent CN2470399Y and a jet-propelled snow sweeper provided by CN 104074164B.
