DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow melting machine for treating snow in a snow-covered area, and to a water sprinkler used for the snow melting.

[0002]

2. Description of the Related Art Such a water spraying device of a snow melting machine sends snow melting water to a water spray pipe by a submersible pump or the like, and continuously installs a number of small-diameter nozzles in the water spray pipe or a large number of small water nozzles in the water spray pipe. A plurality of nozzles having a diameter or flattened nozzles are provided so that snow-melting water is evenly sprayed into the snow-melting chamber so that the snow is evenly melted.

Further, as shown in Japanese Utility Model Application Laid-Open No. 64-28420, a discharge port is opened upward, an umbrella-shaped watering reflector is provided above the discharge port, and snowmelt water is supplied around the discharge port. Circular diffusers are known.

[0004]

In the case of using the small-diameter nozzle as described above, there is a case where dust contained in snow-melting water is clogged in the nozzle and water cannot be sprinkled. In other words, a filter is provided in front of the submersible pump to prevent garbage from passing through the water sprinkling pipe. However, since snowmelt water contains a large amount of garbage, a fine-grained filter can quickly become clogged. Further, since the amount of water spray cannot be increased with a fine-grained filter, the snow-melting effect by water spray is reduced.

Further, when an umbrella-shaped watering reflector is provided above the discharge port to diffuse snowmelt water in a circular shape around the discharge port, the amount of ineffective watering is large and the watering efficiency is low.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a water spraying device for a snow melting machine, in which a water spray nozzle is hardly clogged with dust, can be easily removed even if clogged, and can uniformly spray water throughout the snow melting chamber.
