Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to the configuration of a hot water tank in a mobile snow melting machine that removes snow by melting snow and removing it as water.

(b) Prior art Mobile snow melting machines have been known for some time.
For example, Japanese Patent Application Laid-Open No. 60-261813.

In these technologies, a plurality of jet ports are arranged on the same heat exchanger, and the height of the jet ports is constant.

(c) Problems that the invention aims to solve With this configuration, the height of the boiling water rising was constant, and snow could only be melted up to a certain height. As a result, it was not possible to melt snow over a wide area and continuously, making it time consuming and inefficient.

Furthermore, when the heat exchanger is constructed of a single can with a double structure, differences tend to occur in the discharge pressures from the plurality of ejection ports, and the amount melted varies depending on the position.

(d) Means for solving the problem In view of the above points, the present invention is constructed as follows.

The combustion tank has a double structure, the inner space is used as a combustion chamber, the outer space is used as a hot water tank, and a plurality of spouts are provided at the top of the hot water tank to protrude into the snow melting tank. The water tank is divided into multiple parts, and the height of the spout is changed for each hot water tank.

(e) Embodiment The purpose of the present invention is as described above, and the structure of the present invention will be explained based on the structure of the embodiment shown in the attached drawings.

Figure 6 is a partial side sectional view of a snow melting tank that is discharged using a pump, Figure 7 is a side sectional view of a snow melting section that is discharged naturally, and Figure 8 is a front view when the combustion tank has a two-stage structure. A cross-sectional view, FIG. 9 is a front cross-sectional view of a combustion tank with two stages of ejection ports, and FIG.
FIG. 11 is a side sectional view of the spout mounting portion.

The overall configuration will be explained with reference to FIGS. 1, 2, and 3.

Running wheels 2, 2 are mounted at the center of both sides of the fuselage frame 1.
Alternatively, a crawler is provided, and a handle 3 protrudes rearward from the rear end of the body frame 1. Further, an operation box 7 is attached to the rear surface of the fuselage frame 1, a burner 8 is housed inside, a fuel tank 9 is mounted above, and an ignition switch, a pump switch, etc. are attached to the side.

On the fuselage frame 1, there is a combustion tank 5 of the present invention.
A snow melting tank 6 into which snow to be removed is placed on top of the combustion tank 5. A suction/drainage tank 10 is protruded from the front end of the snow melting tank 6, and a drainage port 11, a water intake port 12,
13 are provided.

As shown in FIGS. 4 and 5, the combustion tank 5, which is the main part of the present invention, has a U-shaped can body, double-structured combustion tanks 5L and 5R, and both are separated on the left and right sides. They are symmetrically arranged and constructed in a box shape, with the inner space serving as a combustion chamber A and the outer spaces serving as hot water tanks B and B'.

A plurality of openings 5a, 5a, 5b, 5b, . ,15,1
6, 16, and so on.

On the front of the combustion tanks 5L and 5R, a front plate 5c,
5d, rear plates 5e and 5f are welded and fixed to the rear surface, hot water tanks B and B' are sealed, and the front plate 5
Communication holes 5g and 5h are opened in the lower portions of the pipes c and 5d, and a pipe 17 communicating with the water intake port 12 is fixedly installed in the communication holes 5g.

In addition, a pipe 18 communicating with the water intake port 13 is fixed in the communication hole 5h, and the hot water tank B,
It communicates with B′.

A pump 14 is provided in the middle of the pipe 18 so that hot water is forcibly circulated and discharged from the spout 16.

An opening 5i for communicating with the burner 8 is provided at the center of the rear plates 5e, 5f, and an opening 5j for exhaust gas is provided at the front of the combustion tank 5L, which communicates with the chimney 19. There is.

These combustion tanks 5L and 5R are fixed to the fuselage frame 1 with bolts.

Inverted funnel-shaped guide pipes 20, 21... are fixedly installed in the openings 5a, 5a, 5b, 5b..., and jet ports 15, 1 are provided at the tips of the guide pipes 20, 21...
6... is fixedly installed. The guide pipe 20 is configured to have a lower height than the guide pipe 21, and the spout 15 melts snow at lower positions, and the spout 16 melts snow at higher positions to widen the snow melting range.

Fig. 8 shows the guide pipes 20 and 21 having the same height and the combustion tank 5L' being higher than the combustion tank 5R' to change the height of snow melting. The tips of pipes 20 and 21,
As shown in FIG. 10, as threaded parts 20a and 21a,
A spout 15' is threaded onto the guide pipe 20.

As shown in FIG. 11, a Γ-shaped connecting pipe 22 is connected to the guide pipe 21 by a joint 23.
A spout 16' is attached to the tip of the connecting pipe 22,
The structure is such that hot water is spouted from the top of the snow melting tank 6 to melt snow from above and below.

(f) Function of the device In this configuration, the water absorption/drainage tank 10 is filled with water up to the lower surface 6a of the snow melting tank 6, and the burner 8 is ignited to heat the inside of the combustion chamber A to reach a certain temperature. If snow is thrown into the snow melting tank 6 at this time, the water in the hot water tanks B and B' will be heated and the combustion tank 5 will be heated.
The hot water in the hot water tank B' of L is injected from the spout 15 due to thermal expansion and its internal pressure to melt the snow in the low position in the snow melting tank 6, and the discharged water is sent to the water inlet 12.
It is replenished by

In addition, the hot water in the hot water tank B of the combustion tank 5R is injected from the spout 16 located higher than the spout 15 by pressure feeding by the pump 14, melting the snow at the higher position, and the water after being melted is transferred to the suction/drainage tank. 10, part of the water is absorbed again through the water intake ports 12 and 13 and circulated for snow melting, and the rest is discharged to the outside of the machine through the drain port 11.

(G) Effects of the invention Due to the structure and operation described above, the present invention has the following effects.

First, since the hot water tank was divided, it was easier to create a double-walled and sealed structure, which reduced the labor involved in assembling it.

Second, since a plurality of hot water tanks are provided, each with a different spout height and discharge pressure, the range of snow melting in the snow melting tank is expanded and snow can be melted efficiently.

Thirdly, because each divided hot water tank is independent, the influence of water jet from the spout and water absorption from other hot water tanks is reduced, making it possible to obtain stable jetting. .
