[Means for Solving the Problems] To solve the above problems, the following means are used. That is, the present invention, the furnace body is arranged in the snow melting tank, hot air is blown into the furnace body by a burner arranged on one side of the furnace body, and snow is removed between the furnace body heated by the burner and the snow melting tank. In the snow melting machine that throws in the snow, the furnace body is formed into a tubular shape in a front cross-sectional view, the side surface of the furnace body on the side opposite to the burner is inclined, and the inside center of the inclined portion is reinforced in a mountain shape in plan view. A plate is provided in the inclined direction so that the tip of the hot air is branched and guided, and the upper end portion of the inclined portion of the furnace body is made to protrude from the cylindrical inclined surface to form a protruding portion, and the top portion of the protruding portion and the cylindrical shape. Hot air holes are opened on each side.

[0005]

With this structure, the hot air from the burner flows backward along the inclined portion of the furnace body and is split into right and left by the reinforcing plate, and the hot air is uniformly ejected from the furnace body to the snow melting tank. be able to. In addition, snow that is pressed against the furnace body by the hot air blown from the projecting portion of the inclined portion of the furnace body, the hot air hole that opens at the top of the furnace body, and the hot air hole that opens toward the furnace body side, and is solidified. Even if it is divided into left and right and the front side, it becomes water while sinking along the slope, and the water after melting can be discharged from the drainage pipe.

Further, the reinforcing plate 15 has a function of reinforcing the front surface portion of the furnace body 1 to avoid deformation and perforation of the burner 7 due to heat.

The top portion 1b at the upper end of the side surface portion of the furnace body 1 is joined as a vertical side by joining the steel sheet ends, and a spacer 12 is provided on this joining surface to form a gap, and this gap is used as a hot air hole 1c. The hot air is blown upward, and similarly, a spacer 12 is provided on the mating surface of the tops 1f of the protrusions 1d and 1d on the front face to form a gap, and the hot air is blown upward as a hot air hole 1g. I have to. Thus, as shown in FIG. 6, the tops 1b and 1f of the furnace body 1 are
The hot-air holes 1c and 1g are provided in a T shape in a plan view, and the introduced snow is pressed from above by the contact of the hot air blown from the hot-air holes 1c and 1g with the snow at the tops 1b and 1f. Even if it is no longer, it can be split into both left and right sides and the front side, and it can fall and melt along the slope due to its own weight.

As shown in FIGS. 3 and 7, hot air holes 1e and 1e, which are larger than the hot air holes 1a provided on the side surface, are provided on the rear side of the projecting portions 1d and 1d of the furnace body 1 to shield the shield. As shown in FIGS. 3 and 5, the restriction plates are opened so as to be located above the plate 16 and located at the inner upper positions of the hot air holes 1e and 1e, respectively, and the tip portions thereof are in a chevron shape when viewed from the front and are aligned with the inclination. 17, 17 are fixedly provided so as to cover the upper half of the circumference, and the hot air from the burner 7 is regulated by the regulating plate 1.
At 7/17, the hot air holes 1e and 1e are guided so that the hot air holes 1e and 1e are jetted to the inclined surfaces on the upper sides of both side surfaces to melt the thrown snow. A non-combustion oil receiving plate 11 having a chevron shape in a front view is fixed between the lower inside of the front surface of the furnace body 1 and the lower end of the combustion tube 9.

Although the recess 2b on the lower surface of the snow melting tank 2 protrudes to the inside of the snow melting tank 2, the furnace body 1 does not have a bottom surface portion, so it is not necessary to process it according to its shape, and the combustion cylinder 9 Neither does it interfere with the non-combustion oil receiving plate 11. And
Since the recess 2b is soaked in the cooling water, the temperature rise can be suppressed, and even if the wheels 14 are housed, the ground clearance is not increased and the throwing height can be suppressed low. In addition, at the upper part of the inner side surface of the snow melting tank 2, the input sensor plate 8 shown in FIG.
The burn-in sensor plate 8 is configured so that the burner 7 operates when snow is thrown in and pushed, and the burner 7 automatically stops when the snow melts and is no longer pressed.

In the case of performing the snow melting work with the movable snow melting machine constructed as described above, when the snow melting machine is moved to the snow removing work position, the sled 13/13 is kept on the snow.
On the ground without snow, the wheel storage lever 6 is operated to cause the wheels 14 to project downward and the wheels 14 move. Then, when the power switch 21 is turned on at the snow removing work position to make the burner 7 operable and the snow-removed snow is put into the snow melting tank 2, the burner 7 is ignited via the input sensor plate 8 and the heat thereof is generated. The furnace body 1 is heated by the heat, and the snow introduced by the heat and the hot air blown out from the hot air holes 1a is melted, and even if the snow is pressed against the furnace body 1 and solidified, the hot air on the tops 1b and 1f The holes 1c and 1g and the hot air from the hot air holes 1e of the projecting portion 1d are broken by being contacted with each other, and fall into the water while sinking. The melted water is discharged from the drainage pipe 10.

Further, although the snow melting machine of this embodiment is constructed as a movable type, as shown in FIG. 8, it is also possible to construct it as a buried type snow melting machine. That is, the inside of the snow melting tank 30 which can be buried and whose bottom surface is inclined from one side to the other side is partitioned by the burner mounting plate 31, the burner 7 is disposed at a high position thereof, and the burner chamber cover 34 covers the burner. A snow melting chamber 33 in which the furnace body 1 is arranged at a lower position than the chamber 32 is configured, and the mud chamber 38 is provided at the lowest position of the snow melting chamber 33.
When performing snow melting work, the upper lid 35 is opened and the power switch 36 is turned on via the air suction portion 29 to make the burner 7 operable, and the snow melting chamber 33
When snow is removed from the inside, the operation switch 37 is turned on via the input sensor plate 8 to ignite the burner 7,
The furnace body 1 is heated by the heat, and the snow introduced by the heat and the hot air blown from the hot air holes 1a is melted, and even if the snow is pressed against the furnace body 1 and solidified, the top 1
Hot air holes 1c and 1g of b and 1f and hot air holes 1e of the protruding portion 1d
The water after being melted is discharged from the mud chamber 38 through the drainage pipe 39 to the manhole 40.

[0016]

Since the present invention is constructed as described above, it has the following effects. That is, the hot air from the burner is reversely flown by the inclined part formed on one side of the furnace body and the reinforcing plate provided in the center of the inside of the inclined part, and the hot air is diverted to the left and right to be uniformly ejected from the furnace body to the snow melting tank. As a result, the snow melting ability is significantly improved, the work efficiency is improved, and the cost such as fuel cost can be reduced. In addition, even if the snow is pressed into the furnace body by the hot air blown from the protruding part of the inclined part of the furnace body and the upper part and the hot air holes that open toward the furnace body side, the left and right and the inclination direction. Since it is possible to melt the snow by dropping it along the slope, it is not necessary to forcibly drop the solidified snow from the upper part of the snow melting tank, and it is possible to reduce the labor at the time of work. Further, the front surface of the furnace body can be reinforced by the reinforcing plate provided in the center of the inside of the front surface of the furnace body to prevent deformation and perforation due to heat of the burner.
