The solid deicing agent and the liquid deicing agent are mixed in the spreading trough 30, and the spinner 40 has power to spin out the solid deicing agent or the mixture of the solid deicing agent and the liquid deicing agent.

[0037] In winter, roads need to be cleared of snow. The spreading device 100 spreads the snow-melting agent on the road surface, which has good snow-removal and ice-control effects and is easy to operate. Snow-melting agents are divided into solid snow-melting agents and liquid snow-melting agents. Solid snow-melting agents take effect slowly but can be effective continuously. Solid snow-melting agents are suitable for long-term snow removal on large roads. Liquid snow-melting agents take effect quickly but cannot be effective continuously. Liquid snow-melting agents are suitable for rapid snow melting, especially in situations where rapid ice removal is required. At present, the spreading devices of snowplows on the market only have one function of solid snow melting or liquid snow melting, which has a limited scope of application and cannot meet the working requirements of more complex working conditions.

[0038] In the embodiment of the present invention, the liquid snow-melting agent in the second snow-melting agent silo 20 can be sprayed directly onto the snow-melting surface to be melted, which is suitable for local small areas or rapid snow removal.

[0081] Of course, in other embodiments, the second bottom outlet 252 may replace the first bottom outlet 242 to communicate with the second connecting pipe 21 , which will not be described in detail here.

[0082] Of course, it is understandable that the multi-way valve can also be a five-way valve, a six-way valve or a valve with more openings. By setting a power water pump 211 on the seventh connecting pipe 32, one end of the seventh connecting pipe 32 is connected to the multi-way valve 50, and the power water pump 211 provides flow power for the liquid de-icing agent, so that the liquid de-icing agent can be pumped out more quickly and conveniently.

[0083] In some specific embodiments, a spray head 31 is provided on the spreading trough 30 , and the spray head 31 is connected to the fourth connecting pipe 511 to spray the liquid snow-melting agent into the spreading trough 30 .

[0084] In some embodiments, the spreading device 100 also includes: a control component, which is electrically connected to the power water pump 211. A liquid level sensor 212 is also provided on the second connecting pipe 21. The liquid level sensor 212 is electrically connected to the control component to control the power water pump 211 to stop working when the water level in the second connecting pipe 21 drops to a set value.

[0085] Among them, the set value is a pre-set value, and the liquid level sensor 212 is used to monitor the water level in the seventh connecting pipe 32. When the water level is at the set value, the liquid level sensor 212 is triggered, and the liquid level sensor 212 sends an electrical signal to the control component, and the control component controls the water pump to stop working.

[0086] In the above scheme, a liquid level sensor 212 is provided on the seventh connecting pipe 32 to monitor the water level. When there is a water shortage, the power water pump 211 is automatically shut down to avoid the power water pump 211 from idling and being damaged due to water shortage.

[0087] The vehicle according to the embodiment of the present invention includes: a vehicle body and a spreading device 100 .

[0088] The spreading device 100 is installed on a vehicle body, wherein the vehicle body is movable, and the vehicle body drives the spreading device 100 to move, and the spreading device 100 spreads while the vehicle body moves.

[0089] According to the vehicle of the embodiment of the present invention, the above-mentioned spreading device 100 is installed. Through the cooperation of the spreading trough 30 and the spinner 40, the liquid de-icing agent can be sprayed alone, the solid de-icing agent can be spread, and the mixture of the solid de-icing agent and the liquid de-icing agent can be spread. Therefore, the spreading device 100 is applicable to a variety of working conditions, the scope of application is increased, and it is adapted to more complex work requirements. The spreading trough 30 is separately provided to provide a mixing space for the liquid de-icing agent and the solid de-icing agent, so that the liquid de-icing agent and the solid de-icing agent are fully mixed, thereby improving the uniformity of snow removal. The spinner 40 is used to throw out the solid de-icing agent and the mixture of the solid de-icing agent and the liquid de-icing agent, thereby increasing the spreading range.
