The overall configuration will be described with reference to FIGS. 1 and 2. Traveling wheels 2, 2 are provided at central portions on both sides of the machine body frame 1, and a handle 3 is projected rearward from a rear end of the machine body frame 1.

An operation box 7 is attached to the rear surface of the machine body frame 1 inside the handle 3, a burner 8 is installed inside the operation box 7, a fuel tank 9 is placed on the upper side, and an ignition switch, a pump switch, etc. are attached to the side surface. I have set up.

A combustion tank 5 is mounted on the machine body frame 1, and a snow melting tank 6 for putting snow for snow removal is placed on the combustion tank 5.

An exhaust hole 19 is opened at the bottom of the side surface 6b of the snow melting tank 6
Hot air from the combustion chamber, which communicates with 19a, passes from between the combustion tank 5 and the bottom plate 6a of the snow melting tank from the upper front portion of the combustion tank and is discharged from the exhaust hole 19 while warming the side plate 6b from the bottom plate 6a. Of.

Further, a suction / drainage tank 10 is provided at the front end of the snow melting tank 6, and the suction / drainage tank 10 is provided with a suction port 13, a drain port 11, a drain 23 and the like.

As shown in FIG. 3 and FIG. 4, the combustion tank 5 has a U-shaped double-structured can body to form combustion tanks 5L, 5L.
R, and both are arranged symmetrically to form a box shape, the space inside is the combustion chamber A, the spaces outside are the hot water tanks B and B ', and the opening 5j provided at the upper front end is exhausted. As a port, it communicates with the exhaust hole 19, and a communication hole 5i provided in the center of the rear surface of the combustion tank 5 communicates with the burner 8.

Each of the combustion tanks 5L and 5R has a plurality of openings 5 on its upper surface.
a, 5a, 5b, 5b ... are opened, and the openings 5a, 5a, 5b, 5b.
The short guide pipe 20 and the long guide pipe 21 are fixedly provided on the upper side, and penetrate the bottom plate 6a of the snow melting tank 6 to be inserted into the snow melting tank 6. And the guide pipe 2
0, 21 ... Nozzles 15, 15, 16, 16 ... Are attached to the upper end.

Water supply holes 5c and 5d are opened at lower portions of the front surfaces of the combustion tanks 5L and 5R, respectively, and a pipe 17 is connected to the water supply hole 5c as shown in FIGS. The other end of
Inserted in the suction / drainage tank 10 and the upper end is the water suction port 17a,
The suction / drainage tank 10 and the hot water tank B are communicated with each other.

Further, a pipe 18 is continuously provided in the water supply hole 5d, and the pipe 18 penetrates the suction / drainage tank 10 and has its upper end projected from the suction / drainage tank 10 to a position slightly lower than the nozzle 16 (about 70 mm). It is extended and has the upper end as an opening 18a.

Further, a connecting pipe 22 is continuously provided in the middle of the pipe 18,
The other end of the connecting pipe 22 is connected to the discharge side of the pump 14, and the upper end on the water absorption side of the pump 14 serves as a water intake port 13 for absorbing and draining water.
And the water supply hole 5d are communicated with each other.

(F) Action of the device With such a configuration, water is supplied to the suction / drainage tank 10,
When the bottom plate 6a of the snow melting tank 6 is filled to the height of the snow melting tank 6 and snow is thrown into the snow melting tank 6 and the burner 8 is ignited to heat the inside of the combustion chamber A, the water in the hot water tanks B and B ′ is heated and boils. .

Next, the hot water in the hot water tank B of the combustion tank 5L is sprayed from the nozzle 15 by thermal expansion and its internal pressure to melt the snow at the lower position in the snow melting tank 6, and the water for the discharge is replenished by the water intake 17a. It is.

The hot water in the hot water tank B ′ of the combustion tank 5R is released from the upper end of the pipe 18 even when being pumped by the pump 14 until it boils, so that the water level in the guide pipe 21 is equal to the upper end of the pipe 18. Therefore, it is not ejected from the nozzle 16.

However, when the hot water in the hot water tank B'boils, it is sprayed from the nozzle 16 located higher than the nozzle 15 by the thermal expansion and its internal pressure in addition to the pressure of the pump 14 to melt the snow in the higher position.

Then, the melted water flows into the suction / drainage tank 10, part of which is again absorbed by the suction ports 17a and 13 and circulated for snow melting, and the rest is discharged from the discharge port 11 to the outside of the machine. .

(G) Effect of the Invention With the above-mentioned configuration and operation, the present invention has the following effects.

First, since the low nozzle 15 and the high nozzle 16 are provided, it is possible to melt the snow at both positions.

Second, the low nozzle 15 is a pipe with no pump 14 interposed.
Although it is connected by 17, the discharge port is located slightly higher than the water storage surface of the suction / drainage tank 10, so that the boiling water in the hot water tank B begins to be discharged from the nozzle 15 where the boiling water is low due to thermal expansion and internal pressure. To do.

Further, the high nozzle 16 is communicated with the pipe 18 through which the pump 14 is interposed, but since the vent hole for releasing pressure is provided on the discharge side of the pump, it does not spout from the high nozzle 16 at low temperature. , Only when the water in the warm water tank boils,
Due to the thermal expansion and the internal pressure, it is possible to jet the hot water from the nozzle 16 at a higher position, and the boiling of the hot water tank B and the hot water tank B ′ allows the hot water to be jetted simultaneously from the low nozzle 15 and the high nozzle 16. , It became possible to melt snow efficiently.

Thirdly, if hot water is discharged from the nozzle 16 before boiling, the temperature does not rise forever and the snow melting efficiency deteriorates. However, in the present invention, the nozzle 16 must always boil after boiling. Since the high temperature water is discharged, the snow melting efficiency can be improved.
