BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various types of snow melting devices such as a hand-operated type, a self-propelled type, and a stationary type, which are used for snow melting work in heavy snowfall areas.

[0002]

2. Description of the Related Art Conventionally, a plurality of steam injection holes have been opened in a snow recovery tank, and a water tank connected to the injection holes,
There is known a snow melting device including a burner for heating water in the water storage tank. This snow melting device is for melting the snow in the recovery tank by heating the water in the water tank by the operation of the burner to generate steam, and the steam ejects into the snow recovery tank through the injection holes. .

[0003]

However, in the above-mentioned conventional apparatus, since it takes a certain time to heat the water in the water storage tank, the snow melting efficiency at the beginning of combustion of the burner is poor, and the exhaust heat from the burner is not sufficient. Had the drawback of being wasted. The present invention has been made in view of such conventional circumstances, and the purpose thereof is to effectively use the exhaust heat from the burner to perform more efficient snow melting,
Another object of the present invention is to provide a snow melting device having excellent snow melting efficiency in the early stage of combustion of the burner.

[0004]

In order to achieve the above-mentioned object, a snow melting device according to the present invention has a steam injection hole in a snow recovery tank and a water tank connected to the injection hole.
A snow melting apparatus comprising a burner for heating water in the water storage tank, wherein an exhaust port of the burner is opened toward the snow recovery tank.

[0005]

According to the above construction, the exhaust air from the burner is directed toward the inside of the snow recovery tank, and the synergistic effect of the exhaust heat and the steam injection heat significantly improves the snow melting efficiency. Further, even in the initial combustion state of the burner when the water in the water storage tank is in a low temperature state, a predetermined snow melting effect is obtained by the exhaust heat from the burner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the snow melting apparatus according to the present invention will be described below with reference to the drawings. In the figure, 1 is a heating tank 2, a water storage tank 3,
A hand-pulled truck 5 equipped with a snow collecting tank 4 indicates a burner.

The trolley 1 is formed by using a steel plate or the like into a box shape whose lower surface is open as shown in FIG. 2. Wheels 6 and 6 are accommodated in the left and right side portions inside thereof, and The heating tank 2 in the part sandwiched by the wheels 6, 6
Then, a water storage tank 3 located above the heating tank 2 is integrally connected, and a snow collecting tank 4 located above the water storage tank 3 is installed on the upper surface of the cart 1.

On the rear side of the carriage 1, a burner 5 communicating with the heating tank 2 and a fuel tank 7 communicating with the burner 5 are provided.
And the handle 8 for manually pushing the cart 1 is installed. Folding stands 9a and 9b are vertically provided on the middle portion of the handle 8 and the outer bottom wall of the heating tank 2.

A plurality of through holes 3b, 3b ... (6 places in this embodiment) are opened in the upper wall of the water storage tank 3, that is, the partition wall 3a with the snow collecting tank 4, and steam jetting cylinders are formed in the respective through holes 3b. Install 10. Further, a drainage port 3c is opened on the side wall of the water storage tank 3 to attach a drainage plug 3d, and a snowmelt water return port 3e communicating with the snow recovery tank 4 is provided.

The vapor jetting cylinder 10 is an internal hollow body whose upper surface is closed, and the lower surface opening is made to communicate with the water storage tank 3 and mounted in the through hole 3b. A plurality of steam injection holes 10a, 10a ... Are opened at appropriate intervals on the peripheral wall of the upper end portion of the ejection cylinder 10 protruding into the snow recovery tank 4.

The snow collecting tank 4 is of an inverted trapezoidal type having an open upper surface, and the side surface on the front side of the trolley 1 is opened to form a snow intake port 4a. Shovel 11 is connected. Further, a drain port 4c of snowmelt water communicating with the return port 3e through a communication conduit 4b is provided on an arbitrary side wall. A filter net 4d is provided at the drain port 4c.

The burner 5 is installed with the flame injection port 5a directed into the heating tank 2 in order to heat the water in the water tank 3 to generate steam. In addition, an exhaust pipe 5b for exhausting is extended upward, and a tip portion of the exhaust pipe 5b is curved from an open upper portion of the snow recovery tank 4 toward the inside of the snow recovery tank 4, so that the exhaust port 5c faces the snow recovery tank 4. No The exhaust pipe 5b is formed in a flat tubular shape that is long in the width direction of the snow recovery tank 4 so that the exhaust heat discharged from the exhaust port 5c is spread over almost the entire snow recovery tank 4.

According to the snow melting apparatus of the present embodiment having the above-mentioned structure, when the trolley is moved forward by the manual operation of the handle 8, the snow taken in from the tip of the shovel 11 moves up the shovel 11. It is recovered in the recovery tank 4.

Further, the heating tank 2 is heated by the operation of the burner 5 to generate steam in the water storage tank 3, and the steam rises in the respective injection cylinders 10, 10 ... And the respective steam injection holes 10a, 10a. …
Is jetted from inside toward the snow collecting tank 4, and the steam heat thereof melts the snow collected inside the collecting tank 4.

At the same time, the exhaust gas from the burner 5 is discharged through the exhaust port 5c.
To the inside of the snow recovery tank 4 via the
Due to the synergistic effect with the steam injection heat, the snow melting efficiency is greatly improved. Moreover, steam heat is injected from the lower side of the snow recovered in the snow recovery tank 4 and exhaust heat is injected from the upper side, so that the snow melting efficiency can be further improved.

Further, even in the initial combustion state of the burner 5 in which the water in the water storage tank 3 is in a low temperature state, a predetermined snow melting effect can be obtained by the exhaust heat from the burner 5. The snowmelt water generated in the snow recovery tank 4 is recovered in the water storage tank 3 through the drainage port 4c, the communication conduit 4b, and the return port 3e.

In the present embodiment, steam heat is injected from the lower side of the recovered snow and exhaust heat is injected from the upper side, so that the snow melting efficiency can be further improved. Also,
The snow melting water generated in the snow recovery tank 4 is returned to the water storage tank 3 so as to circulate and use the recovered snow.

Although the hand-push type snow melting device is shown in the present embodiment, the present invention is not limited to this, for example, a self-propelled device having a motor linked to the wheels 6 and 6, the wheel 6 It is possible to support various types such as stationary type without the handle 8 etc.

In the stationary type, the shovel 11
In this case, only the upper surface of the snow collecting tank 4 is opened to serve as a snow throwing port.

[0020]

[Effects of the Invention] Since the snow melting apparatus according to the present invention is configured as described above, the snow melting efficiency is significantly improved by the synergistic effect of the exhaust heat from the burner and the steam injection heat, and the water in the water tank is Even in the initial combustion state of the burner in the low temperature state, a predetermined snow melting effect can be obtained by the exhaust heat from the burner.

Therefore, it was possible to provide a novel snow melting apparatus which can effectively use the exhaust heat from the burner to perform more efficient snow melting work and which is excellent in the snow melting efficiency in the early stage of combustion of the burner.
