However, in the related art, the solid deicing agent spreading device and the liquid deicing agent spreading device cannot be combined for operation, and the operation working condition adaptability is low.

[0037] In the embodiment of the utility model, the solid deicing agent bin 10 and the liquid deicing agent bin 20 are connected with the spreading assembly 30 respectively, the spreading assembly 30 can be connected with the solid deicing agent bin 10 alone to spread the solid deicing agent, can be connected with the liquid deicing agent bin 20 alone to spread the liquid deicing agent, and can be connected with the solid deicing agent and the liquid deicing agent at the same time to spread the mixture of the liquid deicing agent and the solid deicing agent, thereby adapting to various working conditions, increasing the applicable range, and adapting to complex working requirements.

[0038] Specifically, the solid deicing agent includes sodium chloride (NaCl), calcium chloride (CaCl2) and magnesium chloride (MgCl2).

The salt water solution is usually a sodium chloride (NaCl) or calcium chloride (CaCl2) aqueous solution. The alcohol solution includes a methanol solution and an ethanol solution.

[0039] According to the embodiment of the utility model, the solid deicing agent bin 10 and the liquid deicing agent bin 20 are connected with the spreading assembly 30 respectively, the spreading assembly 30 can be connected with the solid deicing agent bin 10 alone, spreading solid deicing agent, can be connected with the liquid deicing agent bin 20 alone, spreading liquid deicing agent, can also be connected with the solid deicing agent bin and the liquid deicing agent bin simultaneously, spreading the mixture of liquid deicing agent and solid deicing agent, thereby adapting to various working conditions, increasing the applicable range, adapting to more complex working requirements.

[0040] In some embodiments, the instruction receiving module comprises a set spraying amount input component, the liquid deicing agent bin is provided with a liquid output amount control component, and the control module is connected with the set spraying amount input component and the liquid output amount control component respectively.

[0041] The target spraying amount of the liquid deicing agent is the set spraying amount, and the liquid deicing agent bin 20 outputs a certain amount of liquid deicing agent, that is, the liquid output amount.

[0043] Specifically, the set spraying amount input component is a touch screen or an input key, and the operator operates on the touch screen or the input key, which facilitates control and makes the amount of spraying more consistent with the actual working condition.

[0044] Specifically, the set spraying amount can be manually input by the operator through the operation screen, or the control module can automatically determine according to the acquired road surface condition. The liquid output amount can be controlled by the opening size of the liquid deicing agent bin 20, and the liquid output amount control component is used to control the opening size, or the liquid output amount control component is used to control the water pump power on the liquid deicing agent by changing the water pump power.

[0045] In some embodiments, a speed detection component is arranged on the device body, the speed detection component is used to acquire the moving speed, and the speed detection component is connected with the control module.

[0046] In the above scheme, the liquid output amount of the liquid deicing agent bin 20 is controlled according to the moving speed of the spreading device 100, so that the target to be sprayed in unit area is sprayed with sufficient amount of liquid deicing agent, thereby improving the working effect and further improving the adaptability.

[0047] In the above scheme, the liquid output amount of the liquid deicing agent bin 20 is controlled according to the moving speed of the spreading device 100, so that the target to be sprayed in unit area is sprayed with sufficient amount of liquid deicing agent, thereby improving the working effect and further improving the adaptability.

[0048] For example, the spraying width L, the vehicle speed V, the required spraying amount per square meter A, and the real-time output amount Q of the salt water pump 32 are Q=L*V*A, wherein the spraying width L is a fixed value, the required spraying amount per square meter A is inputted by the operation screen, and the Q value needs to change with the change of the V value, so as to guarantee the spraying amount per square meter.

[0049] With reference to Figure 1 , Figure 2 In some embodiments, the spreading assembly 30 comprises a spraying pipeline 31 connected to the liquid deicing agent bin 20 through a water pump 32, the water pump 32 is electrically connected to a driving motor, and the driving motor is connected to a control module through an electric proportional valve.

[0050] The control module adjusts the current of the electric proportional valve according to the set spraying amount and the moving speed, draws the liquid deicing agent through the water pump 32, and pumps the liquid deicing agent to the target to be spread through the spraying pipeline 31.

[0051] In the above scheme, the liquid output amount is accurately controlled through the cooperation of the electric proportional valve and the driving motor, and waste is avoided.

[0052] For example, a one-to-one correspondence relationship between the output flow of the water pump 32 and the hydraulic motor speed and the electric proportional valve current is set in the control assembly, when the vehicle speed V changes, the system automatically adjusts the electric proportional valve current to adjust the change of Q, and then meets the demand for the spraying amount per unit area A.

[0054] The liquid deicing agent in the first water tank 21 and the second water tank 22 can be circulated, and the switching valve 386 at the outlet of the water pump realizes switching to circulate or discharge the liquid deicing agent.

[0055] Specifically, there are two liquid de-icing agent silos 20, namely a first water tank 21 and a second water tank 22. When the liquid de-icing agent circulates in the two liquid de-icing agent silos 20: the drain valve 381 is closed, the water inlet valve 384 is closed, the water tank outlet valve 382 is opened, the opening of the switching valve 386 is turned towards L1 to connect L3 and L1, the water pump 32 is started to extract the liquid de-icing agent from the first water tank 21 and transport it to the second water tank 22. Both the first water tank 21 and the second water tank 22 are provided with vent holes at the top. Under the action of atmospheric pressure, the liquid in the second water tank 22 will return to the first water tank 21 through the connecting pipe to realize the flow of liquid de-icing agent and keep the temperature and concentration of the liquid de-icing agent in the two water tanks uniform.

[0060] The control module is connected to the solid output control unit and the liquid output control unit respectively, so as to control the ratio between solid de-icing agent and liquid de-icing agent to the set ratio.

[0061] The set ratio is a pre-set ratio that controls the liquid output, so that the solid and liquid de-icing agents are mixed in a certain proportion, and the resulting solid-liquid mixture can fully exert its effect.

[0062] In the above scheme, the liquid output is adjusted according to the solid output, so that the ratio between solid de-icing agent and liquid de-icing agent is the set ratio, which improves the pre-wetting effect and further improves the working effect.
