when the temperature of the hydraulic oil is too high, the water pump 27 automatically works, the water in the cooling tank 26 is pumped out of the compartment 1 through the guide pipe 28 and then returns to the cooling tank 26, so that the water in the cooling tank 26 circularly flows, the heat dissipation effect is improved, meanwhile, the outdoor temperature is low in winter, the water can be rapidly cooled when passing through the guide pipe 28 outside the compartment 1, the cooling effect on the piston rod 9 is further improved, and the temperature of the hydraulic oil is reduced; the snow storage hopper 30 is arranged, so that the snow blower can collect external floating snow while working, the snow falls into the snow storage hopper 30, enters the guide pipe 28 through the one-way valve after being melted, the water temperature in the cooling tank 26 is further reduced, a better cooling effect is achieved, and when the temperature of hydraulic oil is reduced to a certain value, the water pump 27 is automatically closed so as to circulate; the auger 33 is pushed to rotate when water flows in the guide pipe 28, and then the first rotating shaft 32 drives the second rotating shaft 35 to rotate through the pair of bevel gears, so that the crushing blades 36 rotate and stir snow falling into the snow storage hopper 30, and a certain vibration effect is generated, so that the melting efficiency of the snow is improved, and the condition that the snow water is frozen and cannot smoothly flow into the guide pipe 28 is avoided.
