However, Japanese Patent Application Laid-Open No.
In the technology disclosed in Japanese Patent No. 257515,
The upper and lower sides of the main frame are completely separated by a midsole plate into a heating chamber and a snow throwing chamber, so that the hot air of the burner does not contact the snow in the snow melting chamber to have a snow melting action. Further, in the technology described in Japanese Utility Model Laid-Open No. 55-136822, a snow melting device of a traveling type is used, in which a front portion in a traveling direction is opened and snow is taken in from the snow melting device. It is unlikely that the snow will be covered by the snow melting cylinder, and the top surface of the snow melting cylinder will only be covered if the traveling fuselage and the snow melting cylinder part can completely penetrate under several meters of snow. However, since the snow actually falls before such a situation occurs, there is a problem in that the hot air leaks while the blowing hole on the upper surface of the snow melting cylinder is always open.
The present invention has solved such disadvantages of the prior art. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The objects and constitutions of the present invention are as described above, and the constitution of the embodiment shown in the attached drawings will be described.
FIG. 1 is a front sectional view of an embedded snow melting apparatus of the present invention, FIG. 2 is a side sectional view of the same, and FIG. 3 is a plan view of the same with a lid removed.

The snow melting apparatus of the present invention is dug up at an appropriate place in the site, and is buried with the opening above the main body frame 4 left open. A heat insulating material 25 is attached to the outer surface of the main body frame 4 to keep it warm. The effect is enhanced. The lid 5 is pivotally connected to one side of the opening via a hinge 24, and when the lid 5 is closed, the lid 5 can freely walk on the snow melting device so that the snow melting device does not get in the way. I have. The lid 5 is a damper 2
7, so that it can be easily opened and closed. 23 is a handle. The snow melting cylinder A and the operation box 22 for the submersible pump are attached to the back surface of the lid 5.

The inside of the main body frame 4 is divided into right and left by a partition plate 3, and a machine frame 6 is provided inside one side as a snow melting room 1. The snow melting cylinder A is a burner 26
The burner 26 protrudes into a duct 30 formed by being separated by a side plate 29 so that air can be sucked in. The hot air and combustion gas emitted from the burner 26 pass through the snow melting cylinder A. , Is blown out upward from the blowing holes 31a, 31a ...
The inside of the snow-melting cylinder A also serves as a chimney to simplify the structure. The water after the dissolution is discharged from the drain 7 opened in the bottom of the machine frame 6, and the bottom of the machine frame 6 is lower on the burner side. Then, the first pump chamber 8 is formed by being dug deeper in one corner of the main body frame 4, and the snow melted in the snow melting chamber 1 is stored. The drain 7 is covered with a net or the like to remove dust and the like.

A submersible pump 9 is disposed in the first pump chamber 8, and a discharge port of the submersible pump 9 has a pipe 1.
0 is communicated, and the other end of the pipe 10 is a shower pipe 1
It is connected with 1,12.

The shower pipe 11 is a shower pipe 12
The pipe diameter is made smaller, so that only a small amount is discharged and only about 25% of the whole is discharged, and pipes are piped around the upper surface along the wall surface of the snow melting chamber 1 so that the snow put into the snow melting chamber 1 is formed on the side plate. It is designed to smoothly fall onto the snow-melting barrel A so that it does not adhere and fall.

Since the shower pipe 12 has a large pipe diameter, it can discharge a large amount of hot water. The shower pipe 12 is piped around the shower snow melting chamber 2 on the other side, which is partitioned by the partition plate 3, and inside the shower snow melting chamber 2. It is discharged to melt the snow that has been thrown in. A drain 13 is also provided on the lower surface of the shower snow melting chamber 2, and a second pump chamber 14 is provided below one corner of the lower surface.

An automatic submersible pump 15 similar to the above is disposed in the second pump chamber 14, and a pipe 16 communicates with a discharge port of the submersible pump 15, and communicates with a shower pipe 18 at an intermediate portion of the pipe 16. However, the snow in the center of the shower snow melting chamber 2 is melted. Then, the end of the pipe 16 comes out of the main body frame 4 and faces the inside of the sewer groove 20 so that the snowmelt water is discharged.

In such a configuration, the snow removed can be put into the snow melting chamber by opening the lid 5 without lifting, and the snow put into the snow melting chamber 1 is put on the upper plate 31, The combustion gas from the burner 26 is blown out from the blowout holes 31a, 31a,... And the heat melts the snow and falls to the bottom of the machine casing 6. The machine frame 6
Since the bottom portion is slightly lowered on the burner side, it is heated while being stored there, and hot water of about 25 degrees is drained from the drain 7 and stored in the first pump chamber 8.

When a certain amount of hot water in the first pump chamber 8 accumulates, the submersible pump 9 operates to reach the shower pipes 11 and 12 via the pipe 10, and the discharge amount is small because the pipe diameter is small from the shower pipe 11. And about 25% of the total amount of snowmelt water is discharged to the vicinity of the side plate of the snowmelt chamber 1 so that the snow falls smoothly downward and reaches the snowmelt cylinder A.

Most of the hot water is discharged from the shower pipe 12 toward the center of the shower snow melting chamber 2 from above.
The snow in the shower snow melting chamber 2 is melted. The water that has melted enters the second pump chamber 14 from the drain 13,
When a certain amount or more is accumulated in the second pump chamber 14, the submersible pump 1
5 is operated, and a part from the pipe 16 is a shower snow melting room 2
Discharged from a shower pipe 18 provided in the middle part of the inside, the snow adhering to the side surface is melted to lower the snow in the shower snow melting chamber 2 downward.
Is discharged. Although the temperature of the water discharged here is about 5 degrees, unlike the case of discharging on the road surface, there is no problem because the water flows directly into the sewer.

[0015]

With the above-mentioned structure, the present invention can obtain the following effects. First, a cylindrical snow melting tube A is arranged inside the snow melting chamber 1 formed by the main body frame 4, and the upper and side portions of the snow melting tube A are configured as a snow melting space,
Since the snow is thrown into the snow melting chamber 1 at the upper part of the snow melting cylinder A, the snow placed on the upper surface of the snow melting cylinder A and the snow arranged on the side surfaces are gradually removed from the surface of the snow melting cylinder A. In addition, since the heat can be melted by the heat discharged from the blowing hole 31a of the upper plate 31 of the snow melting cylinder A, the heat of the burner 26 can be used effectively, and a buried snow melting apparatus with good thermal efficiency can be provided. It was done.

Second, since the snow is thrown into the portion of the snow melting chamber 1 opened to the ground, the operation of covering the snow on the top and side surfaces of the snow melting cylinder A can be easily performed. It is possible to arrange snow so that hot air does not leak from the outlet hole 31a of the upper plate 31. With this configuration,
Heat is not wasted and a large amount of snow can be melted with a small amount of kerosene.

Thirdly, the snow remaining on the side surface of the snow-melting cylinder A in a bridge-like manner has its surface replaced by water due to both the surface of the snow-melting cylinder A and the hot air from the blowing hole 31a, and this water is used as lubricating water. As a result, the bridge snow begins to slide down the sides immediately. As a result, immediately after the snow storm, the bridge-shaped snow starts to descend immediately, and the snow melting cylinder A
Is dipped in the snowmelt water at the bottom of the body frame 4 and is effectively melted, so that the snowmelt speed can be increased.

Fourth, a chimney is usually required as an outlet of the flue gas from the burner 26. In the buried snow melting apparatus of the present invention, the flue gas from the burner 26 passes through the snow melting cylinder A through the passage. Since the exhaust gas is discharged as a chimney, a chimney is not required and the cost is reduced as a simple configuration.
Since it is blown out from 1a, 31a, and is used as snow melting heat, the snow melting ability can be improved by the amount of the combustion exhaust gas.

Fifth, snowmelt water is collected in the pump room 8 and
Discharged by middle pump 9 and melted from shower pipe 11
By injecting it into the chamber 1, the snowmelt water whose temperature has risen
Can be used, so this will also improve snowmelt efficiency
It can be improved. Also, from the snow melting room 1
In order to remove dust and dirt, a net etc.
Cats that get mixed in the snow
Can remove dog droppings and hair, etc.
It can improve the durability.
