人工降雪装置に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an artificial snow-making device that can be used for snow exposure tests of various equipment, their parts, and materials, and displays of various products, and in particular, an artificial snow-making device that applies water vapor to the cooling surface. This invention relates to an artificial snow-making device that scrapes ice and frost formed on the surface of a liquid and makes it fall to make snow.

この種の人工降雪装置としては、内周面を冷却できるよ

ドラムに内蔵した回転ブレードでもって掻き取り落下さ
せるものが知られている。[Prior Art] This type of artificial snow-making device uses a humidifier to flow down water vapor from the top of a cylindrical drum whose inner circumferential surface can be cooled, thereby removing ice, which forms the source of snow, on the inner circumferential surface of the drum. A known method is to form snow or frost (hereinafter referred to as "former snow") and scrape it off with a rotating blade built into a drum.
〔発明が解決しようとする課題］
しかしながら、この種の人工降雪装置によると、円筒ド
ラムの上部から供給された水蒸気は該ドラム内周面に十
分接触することなくドラム下端から流出してしまい、加
湿水量の割りには降雪量が少ないという問題がある。[Problems to be Solved by the Invention] However, with this type of artificial snow-making device, the water vapor supplied from the upper part of the cylindrical drum flows out from the lower end of the drum without sufficiently contacting the inner peripheral surface of the drum, resulting in humidification. The problem is that the amount of snowfall is small compared to the amount of water.
また、前記掻き取りブレードはドラム内周面を撫でるよ
うに進行するだけであるから、該内周面上に形成された
元雪を掻き取るというよりはむしろそこへ撫でつけるよ
うな恰好となり、円滑な播き取りを行うことができない

いという場合もあった。In addition, since the scraping blade only moves as if caressing the inner circumferential surface of the drum, it appears to be caressing the original snow formed on the inner circumferential surface rather than scraping it off, resulting in a smooth surface. In addition to the problem of not being able to perform accurate sowing, there were also cases where the snow shovel blade did not rotate smoothly because it was difficult to position the center of rotation of the snow shovel blade with the center of the drum.
さらに、円筒ドラムから落下する雪は１カ所に集中的に

Even if a large number of such cylindrical drums were prepared and lined up, this problem could not be solved because only a large number of heaped-up snow areas were created.

The purpose is to provide

The water vapor moves from the bottom to the top of the snowmaking chamber. When snow is formed on the inner surface of the vertical panel due to the entry of water vapor, this snow is scraped off by a rolling brush that descends while rotating, and falls downward. Once the rolled brush reaches the lower end of the vertical panel, it is raised to its initial position in preparation for the next snowfall.

たってほぼ均一に積雪する。When enough original snow is formed, the shutter 1 is opened and the rolled brush 3.3 is rotated in the directions of arrows A and B in the figure, along the guide rod 4.4 by the rotation of the screw rod 34 driven by the motor 36. and begins to descend. Thus, the original snow on panel 2.2 is scraped off by said brush 3.3,
It falls downward as snow. Further, snow adhering to the brush 3 is shaken off and falls when the bristles come into contact with the flip-up rod 6 as the brush 30 rotates and are bent and bounced. In this way, snow falls almost uniformly over the length of the rolled brush 3.

より排出される。When each rolled brush 3 reaches the lower end of the panel 2, the shutter 7 is closed again, and each rolled brush 3 is raised to its original position by reverse rotation of the screw rod 34. When the shutter is closed, snow that has accumulated on the shutter is melted by the heater 71 inside the shutter, and the snow that has accumulated on the shutter is melted by the guide groove 72.
It collects at a predetermined position along the line and is discharged from there through a pipe (not shown).

。Further, the roll-shaped brush 3 has a large number of flexible nylon bristles planted radially at a predetermined density, and the length of each bristle is such that it barely reaches the surface of the panel 2. It is said to be the length. According to such a roll-shaped brush 3, each brush bristles can be flexibly bent and vibrated, compared to the case of using a brush whose bristles are made of hard metal, so that the action of the flip-up rod 6 can also be improved. You can help make the snow fall extremely smoothly. The flip-up bar 6 also prevents the rolled brush 3 from clogging.
造雪室１は略直方体に形成されているので、該造雪室を
