BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a wet anti-freezing agent spraying vehicle for spraying a wet anti-freezing agent onto a road surface.

[0002]

2. Description of the Related Art Conventionally, in winter, an anti-freezing agent has been sprayed on ice and snow road surfaces in order to prevent the road surface from freezing. There are two methods of spraying the antifreezing agent, dry spraying and wet spraying, both of which have been put into practical use. Among these methods, a wet antifreeze spraying vehicle (hereinafter, abbreviated as wet spraying vehicle) is used. 4), as shown in FIG. 4, while the powdered antifreezing agent dropped from the transporting end of the antifreezing agent transporting conveyor A is dropped onto the rotary spraying disk C through the chute B, It is widely known that a wetting agent spraying device D is provided obliquely above and a means configured to spray the wetting agent toward the antifreezing agent falling from the chute B and humidify the antifreezing agent is widely known. Has been.

[0003]

However, in such a device, the antifreezing agent is humidified by spraying the wetting agent toward the antifreezing agent falling from the chute B. It is extremely difficult to evenly mix the wetting agent with each other, and part of the wetting agent scatters to make it difficult to adjust to a desired mixing ratio and degree of wetting. In addition, kneading was sufficiently and uniformly performed. There is a problem that an antifreeze agent cannot be obtained. Further, if the wetting agent is uniformly mixed with the antifreezing agent by the above-mentioned method, a highly accurate wetting agent spraying device is required, which is expensive. An object of the present invention is to provide a wet type antifreezing agent spraying vehicle capable of completely eliminating such problems.

[0004]

In order to achieve the above object, a wet anti-icing agent spray vehicle according to the present invention comprises an anti-freezing agent accommodating hopper 2 in a spraying vehicle body 1 and an anti-freezing agent supplied from the hopper. Transport conveyor 3 and this transport conveyor 3

A casing 4 having an upper end opening toward the end of the conveyance of the conveyer 3 is provided between the spraying device 12 and the spraying device 12, and an agitating device 6 is provided in the casing 4 and the casing 4 is placed on the spraying device 12 at a proper position. The anti-freezing agent discharge port 8 is opened, and the wetting agent supply nozzle 11 is arranged above the casing 4.

[0005]

The powdery anti-freezing agent transported by the transport conveyor 3 drops from the transport end of the transport conveyor 3 into the casing 4, is temporarily stored therein, and is temporarily stored by the stirring device 6 arranged in the casing 4. Be stirred. On the other hand, a wetting agent consisting of a solution such as salt water is poured into the casing 4 from a wetting agent supply nozzle 11 arranged in the upper portion of the casing 4, and the stirring device 6 uniformly stirs and mixes with the antifreezing agent. To obtain the desired wetness. In this way, the antifreezing agent that has uniformly wetted in the casing 4 is supplied from the antifreezing agent discharge port 8 of the casing 4 to the spraying device 12, and is sprayed on the road surface by the spraying device 12.
