Description

[Detailed Description of the Invention] The present invention relates to a snow melting device, and more specifically, to a device that is mounted on a car or the like, collects snow from roads, etc., and melts the collected snow.

The current situation is that a huge amount of money and labor is spent every year to remove snow from roads, runways, etc. in snowy areas, and each local government is struggling to deal with it. The most common method was to use bulldozers to push the snow to both ends of the road, leaving only the center of the road passable. The snow that has been removed in the form of walls at both ends is then dumped into nearby rivers, oceans, etc. by trucks, etc., but the effort and cost involved is enormous.

In urban centers, so-called road heating methods have been developed and are in practical use in some areas. This involves embedding a heater in the road and heating the road constantly or intermittently to melt snow.
This road heating method melts snow, so there is no need to dump snow, and in that sense it can be said to be a good snow removal method.However, because the heater is buried, it is not desirable to place a high load on the road, and it is difficult to maintain durability. In addition to poor performance, it also has the disadvantage of extremely high running costs. Therefore,
It is only partially used at the intersection of Main Street.

Another method is to pump up groundwater and spray it with sprinklers to melt snow, but in this case,
Not only does groundwater deplete, causing land subsidence, but, like the road heating method, it has the disadvantage of high running costs. Snow is being considered, but in this case it has been calculated that it would cost 70 million yen a day in water charges alone to clear the snow from a 500m stretch of road.

In view of the current situation, the present inventor has devised various ideas for snow removal and snow melting and has filed applications (for example, Utility Model Publication No. 49-5860, Utility Model Application Publication No. 1983-125122, Utility Model Application Publication No. 55-9327). No., Utility Model No. 55-31838, Utility Model 55
-93260), the present invention is also on the same line as the above-mentioned invention. That is, the present invention focuses on the fact that freshly fallen snow is bulky, light, and easily melts, and is designed to dispose of such freshly fallen snow while maintaining its bulk, and then to melt the snow.

Therefore, the snow melting device according to the present invention includes: a shovel for scooping up freshly fallen snow; a conveyor for transporting the scooped snow; a fan containing water and stirring the water; The snow melting tank is equipped with a heater for heating water, a water spout for distributing water onto the road, etc., and is covered with a heat insulating material.

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic cross-sectional view of one embodiment of the present invention, and as is clear from this figure, the snow melting device according to the present invention has a shovel 2 installed at one end of the conveyor 1.
has. The tip of the shovel 2 is flat and has a thin wall thickness, so that it can scoop up snow immediately after snowfall while remaining bulky and easily melted.

A snow carrying rotating machine 3 is provided at the other end of the conveyor 1. This snow conveying rotary machine 3 conveys the snow carried from the conveyor 1 to the snow melting tank 4, and also has the function of a lid that shields the snow melting tank 4 from the outside air. The tip is bent in the direction of rotation (indicated by the arrow) into a hook shape, and
The bent portion 31 is the edge 41 of the snow entrance 40 of the snow melting tank 4.
It has come to almost come into contact with.

The snow melting tank 4 has an outer wall 42, a heat insulating material 43, and an inner wall 4.
4 to improve heat insulation properties, and a heating chamber 46 equipped with a propane burner 45 is provided at the bottom, and water 49 stored in the snow melting chamber 48 is fed through a partition wall 47 with good heat conductivity. It is designed to heat up.

Furthermore, a hot water pipe 411 is provided on the side of the snow melting chamber 48 via a partition wall 410. This pipe 411 is directly connected to a radiator or the like of an automobile engine, and is a heating device that utilizes engine waste heat. Furthermore, an exhaust heat pipe 412 is provided in the water 49 to allow exhaust gas from the engine to pass therethrough.

In addition, in order to improve the snow melting effect, a snow melting tank 48
is equipped with a water flow fan 413, which generates a flow in the water 49 to facilitate snow melting.

Furthermore, the water 49 increased due to snow melting is drained from the drain 4.
Water is taken in from 14 and sprinkled onto the road from a water spout 415. Note that 416 is a board for preventing outside air from entering through the snow entrance 40, and 417 is a tire.

To explain the operation of one embodiment of the present invention, first, freshly fallen snow is scooped out by the shovel 2, conveyed by the conveyor 1 to the snow carrying rotating machine 3, and the rotating blades 30 are rotated in the direction of the arrow. The snow is transported into the snow melting tank 4 through the snow transport entrance 40.

The snow carried in is transferred to burner 45 and hot water pipe 41.
1. The snow falls into the water 49 that is heated by the exhaust heat pipe 412 and is being flowed by the water flow fan 413, and is melted. The snow that turned into water is drain port 41
Water is taken in from 4 and sprinkled onto the road from a water spout 415.

FIG. 2 is a schematic diagram of the snow melting device of the present invention installed in an automobile. The snow melting tank 4 can be easily moved by tires 417, and is connected to the front of the automobile 5. Further, a rotating brush 50 is provided at the rear of the automobile 5, and is configured to sweep water sprayed from a water sprinkling port 415 and promote melting of snow remaining on the road. 51 is this rotating brush 5
0, and 52 is a fuel tank for the burner 45 in the snow melting tank 4.

According to the present invention, the snow immediately after it has fallen is scooped up with a shovel without being compacted, and the snow is heated by a heater and dropped into warm water with a water flow.
Since it melts snow, it can melt snow extremely efficiently, and since the snow melting tank is covered with a heat insulating material and there is no heat exchange with the outside, it also has the advantage of requiring less heating energy.

In addition, since the water generated by melting snow is sprinkled from the water spout, water does not overflow into the tank, and furthermore, it is possible to prevent the temperature inside the tank from dropping excessively. An additional benefit is that the sprinkled water will melt any remaining snow.

Furthermore, if the snow transfer entrance is equipped with a rotary snow transfer machine, it will not only be possible to efficiently transfer snow into the snow melting tank, but also minimize the inflow of outside air associated with snow transfer. The energy consumption associated with this can be reduced.
