Description

  The present invention, for example, wets a solution (produced by mixing a granular material and a liquid such as water) into a granular material (medicine, solid agent) such as an antifreezing agent or an aggregate, and sprays this. The present invention relates to an improvement of a wet sprayer.

Conventionally, as a method of spraying a granular material such as an antifreezing agent or an aggregate, dry spraying (refer to Patent Document 1) in which the granular material is sprayed as it is, and liquid such as water is moistened to the granular material. This is roughly classified into wet spraying (see Patent Documents 2 to 6).
By the way, in recent years, in order to prevent scattering and to improve the rapid effect, the solution (generated by mixing powder and water and other liquids) is wetted and dispersed in the powder. Attention has been focused on wet spraying of the solution wet type (see Patent Document 5).

However, when performing such wet-type wet spraying, not only the spraying vehicle needs a tank to store the solution, but also the snow removal base is supplied with a solution storage tank or solution that can store the solution. Equipment such as a solution supply system was necessary to do this.
Therefore, in a place without these facilities, it was not possible to perform wet spraying with a solution wet type.

  The present invention has been devised in view of the above-mentioned problems, and has been devised to solve this problem. The intended process is a solution-wet type wet process even in a process without equipment such as a solution storage tank or a solution supply system. The purpose is to provide a wet sprayer that can be sprayed.

  The wet-spreading vehicle of the present invention is basically provided in a vehicle body that can travel, a hopper that is provided in the vehicle body and stores powder particles, a carry-out means that carries powder particles out of the hopper, and a vehicle body. A tank into which the powder and liquid are charged, a stirrer that is provided in the tank and generates a solution by stirring the powder and liquid, a sending means for sending the solution in the tank, and a powder from the carry-out means It is characterized in that it is composed of mixing means for mixing and wetting the solution from the delivery means to the body and spraying means for spraying wet powder particles from the mixing means on the surface to be sprayed.

The hopper is charged with the powder and the tank is charged with the powder and the liquid. In the tank, the charged particles and liquid are stirred and mixed by a stirrer to form a solution.
The granular material stored in the hopper is transported by the transporting means, and the solution stored in the tank is transported by the transporting means. Then, the powder and the solution are mixed by the mixing means to be the wet powder and then sprayed on the surface to be sprayed by the spraying means.

Since the solution is moistened and sprayed on the granular material, the spraying and quick-activities are significantly higher than the dry spraying that sprays the powder itself and the wet spraying that wets and sprays liquid such as water. To be improved.
Since the solution necessary for wetting the granular material is generated in the tank, wet spraying can be performed even in a place without a solution storage tank or a solution supply system.

According to the present invention, the following excellent effects can be achieved.
(1) The vehicle body, hopper, unloading means, tank, stirrer, delivery means, mixing means, and spraying means. Especially, the tank is provided with a stirrer, and the powder and liquid are put into the tank, depending on the stirrer. Since a solution is produced by stirring and mixing, wet spraying can be performed even in a place without a solution storage tank or a solution supply system.
(2) Since only a stirrer is added to the tank, it does not cost much and can be implemented immediately.

Since the wet granular material D in which the solution C is wetted is sprayed on the granular material A, the dry spraying to spray the granular material A itself, or the wet spraying to wet and spray the liquid B such as water on the granular material A Compared to, the scattering and rapid efficacy are greatly improved.
Since the solution C for moistening the granular material A is generated in the tank 5, wet spraying can be performed even in a place where there is no equipment such as a solution storage tank or a solution supply system.

In the above example, the number of tanks 5 is two on the left and right. However, the number of tanks is not limited to this. For example, one or three or more may be used.
In the previous example, the stirrer 6 is single. However, the stirrer 6 is not limited to this.
