Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an artificial snow-making device that is capable of making snow fall continuously without interruption even momentarily.

The applicant's company supplies mist together with low-temperature air to a snow trapping body with a lower opening made of a ventilation structure, causing the fog to freeze on the trapping body, and scraping it with a scraper such as a brush that reciprocates up and down to form a thin layer. We first developed a device to artificially fall snow in the form of ice flakes. ---1-1-" 1, L"
Although the brush is moved in the following directions, the brush stops at the turning point (dead center) and the snowfall stops temporarily.

The present invention is capable of causing snow to fall continuously without any temporary interruption, and the present invention will be described below based on embodiment figures.

In the figure, reference numeral 1 denotes a device facepiece, which has a rectangular parallelepiped frame with a frame 2 as its axis, which has side plates 3, a top plate 4, and a bottom plate 6 with an opening 5 in the center. .

A snow trap 7 in the shape of a cylindrical cap with an open bottom is provided in the device facepiece 1, with the lower portion of the opening brought into contact with the opening 5 of the bottom plate 6 of the device facepiece. , a ventilation material 8 made of a net or coarse cloth-like material is attached to a cylindrical frame made up of vertical and horizontal striations and materials (not shown).

Fog 10 is then supplied from the spray nozzle 9 into the snow trapping body, and low-temperature air 11) below freezing point is sent into the snow trapping body 7, so that the fog freezes on the upper part and the circumferential body of the snow trapping body 7.

The ice that has formed and grown in this snow trapping body is scraped by the upper horizontal rotating brush 12 serving as a scraper, and the ice on the circumference is scraped by a pair of upper and lower brushes 13a and 13b, and the ice falls as artificial snow made of thin ice flakes. let The brushes 13a and 13b for the circumferential body part reciprocate up and down to scrape off ice, but in the present invention, even when one brush 13a or 13b stops momentarily at the dead center, the other brush 13
b or 13a slides, so that the body of the snow catcher is continuously scratched by the brushes 13a and 13b, so that continuous snowfall occurs.An example of the mechanism for this will be explained below. .

The brushes 13a and 13b for the circumferential body are annularly attached to the lower portions of cylindrical frames 14a and 14b, both of which are larger than the snow catcher.

Beams 15a, 15b are provided across the diameter of the upper part of each frame 14a, 14b, and bearings 15a, 15b are provided on the upper part of each frame 14a, 14b.
6a, 16b are provided, and these bearings 16a, 16b
The upper ends of the connecting rods 18a and 18b, whose lower ends are connected by horizontal pins 17a and 17b, are connected to a rotating body to which the rotational force of the motor 19 is transmitted and rotated around a horizontal axis, for example, a rotating plate 20 shown in the figure, which has a phase on both sides. Shift (for example, 9
(with a phase of 0 degrees) are connected by horizontal pins 21a and 21b.

Further, from each frame body 14a, 14b, an arm 22 is provided outwardly.
a and 22b are provided in a protruding manner so that guide rollers 23a and 23b provided at the ends of these arms can roll along vertical rails 24a and 24b provided inside the device case, thereby allowing each frame body to 14a and 14b are guided by rails and can move up and down.

The rotary plate 20 of the embodiment described above is configured to be frictionally rotated by a driving disk 25 attached to the shaft of the motor 19, and the rotary plate 20 is connected to the connecting rods 18a, 1.
8b are connected, so the rotating plate 20 is supported by two receiving rollers 26, 26, 27 is a roller bearing, and 28 is a bearing mounting spar member. shows.

In addition, in the illustration, the reference numeral 29 indicates the horizontal rotating brush 12.
30 is a stay of the motor, 31 is a frame for the motor 19, 32 is a frame mounting beam, and 33 is an air outlet.

In the device of the present invention of the above-described embodiment, the mist sent into the snow trap 7 together with low-temperature air freezes in the snow trap, and this freezes over the horizontally rotating brush 12 and the upper and lower circumferential brushes 13a, 1.
3b, and the snow is artificially fallen into the lower test chamber (not shown).

By the way, in the present invention, there are two brushes 13a and 13b, upper and lower, for scraping the circumference of the snow catcher 7, and each brush 13a, 13b is moved with a phase difference as shown in FIG. 4, for example. Therefore, even if one brush 13a or 13b temporarily stops at the turning point, the other brush 13b or 13a is in motion.

Therefore, the ice on the catcher is continuously scraped off by both brushes 13a and 13b, creating a continuous snowfall without interruption even for a moment.

In the above embodiment, the rotational movement of the motor is controlled by the rotating plate 2.
0 to the connecting rods 18a, 18b, there are various mechanisms for converting rotational motion into reciprocating motion, and instead of the rotating disk 20 of the above embodiment, for example, a crank mechanism may be used. There is also something to do.

Brief explanatory drawings of the drawings show an embodiment of the present invention, and FIG. 1 is a front view with the side plate removed, FIG. 2 is a side view taken along the central longitudinal direction, and FIG. 3 is a partial plan view. FIG. 4 is a diagram showing each movement state of the circumferential brush.
