  The operation of the in-vehicle snow melting device 10 of the present embodiment configured as described above is as follows. First, at the time of snow melting work, the belt conveyor 16 is lowered from the support base 46 at the destination as shown in FIG. 12, the burner 28 shown in FIG. 2 is ignited, and the water in the melt water tank 22 is pumped. 23, the circulation pipe 32 </ b> C is heated and exchanged by the burner 28 while being introduced into the lower tank 32 </ b> A of the heat exchanger 32, thereby rising as hot water and discharged to the upper tank 32 </ b> B. The hot water that has reached the upper tank 32 </ b> B is jetted from the nozzle 36 </ b> A of the hot water sprayer 36 to the inside of the snow outlet 26 through the hot water pipe 38. At this time, snow to be melted is placed on the lower end portion 16B of the belt conveyor 16 by using a scoop or the like, and the belt conveyor 16 is driven to sequentially carry the snow to the vicinity of the snow outlet 26. The snow transported to the vicinity of the snow outlet 26 by the belt conveyor 16 is thrown into the snow outlet 26 and rapidly melted by the hot water jetted from the nozzle 36A of the hot water jet pipe 36 to become water and the net plate 40. It falls into the molten water tank 22 through the gap.

  The water dropped in the melt tank 22 is further supplied to the heat exchanger 32 by the pump 23 and circulates as warm water by the circulation pipe 32C. When the water level in the melt tank 22 exceeds a certain amount, the melt tank It overflows from the discharge port 22A on the side surface 22 and is discharged to the outside. Since the snow melting work is efficiently performed by the respective burners 28 and the heat exchanger 32 in the combustion chambers 24, 24 arranged in parallel, the heat efficiency can be increased even in a small space, and even when loaded on the light vehicle 12, the snow melting is performed. There is no shortage of ability. In other words, when the snow melting device is mounted on a vehicle, it is necessary to use a hot water type instead of a direct fire type, but in the case of a hot water type, a conventional heat exchanger can be downsized due to space requirements. It was difficult, and it was impossible to load all the equipment on one light vehicle. On the other hand, as in this embodiment, the heat exchanger 32 is composed of two tanks, a lower tank 32A and an upper tank 32B, and the lower tank 32A and the upper tank 32B are connected by a circulation pipe 32C. As a result, the heat exchanger itself can be reduced in size, and as a result, the reduced heat exchangers 32 can be arranged in parallel, and the amount of heat necessary for melting snow can be secured sufficiently. Can do. Thereby, even when mounted on the light vehicle 12, sufficient snow melting efficiency can be secured.

  In addition, since all devices necessary for configuring the snow melting device such as the main body case 14, the belt conveyor 16, the generator 18, the operation panel 20, and the kerosene tank (not shown) are mounted on the light vehicle 12, the narrow road Even in such places, as long as the light vehicle 12 can enter, snow melting work can be performed. Furthermore, by reducing the size of the heat exchanger 32, it is possible to operate with reduced fuel consumption when melting snow.

  In addition, although this embodiment demonstrated the case where each apparatus which comprises a snow melting apparatus, such as the main body case 14, the belt conveyor 16, the generator 18, and the operation panel 20, was mounted in the light vehicle 12, of course, it is other than light vehicles. It can also be mounted on a vehicle.

As described above, according to the present invention, since an efficient heat exchanger is used, the entire snow melting device can be reduced in size and can be mounted using a light vehicle or the like. . For this reason, it becomes possible to easily enter even in a narrow road width, and there is an excellent effect that snow melting work can be performed in various places.
