Description

The present invention relates to a snow melting device, and more particularly, to a snow melting processing device that intensively processes snow transported from a snowplow while being pulled by the snowplow.
In detail, the present invention is to finely pulverize the compressed snow lump conveyed by the snowplow via a belt conveyor or the like into a powder form, and guide it to a sloped plate that guides the snowfall flow of the slope installed below, At least two locations upstream and downstream of the guide inclined plate, hot water is sprayed onto the snow on the powder or sherbet to flow down on the snow slide guide inclined plate while melting snow instantaneously, and the flowing snow melt is stored in hot water It has been devised so that it can be led to the tank and accumulated, and even inside the hot water tank, the snow melting treatment can be carried out by jetting hot water.
In the present invention, there is a possibility that the compressed snow lump conveyed from the snowplow may be mixed with hard ice that does not melt instantly even after being subjected to fine powder processing. A means for stirring the hot water storage by jetting hot water is provided as a melting means. Therefore, by preparing the melting environment by the stirring means provided in the hot water storage tank, it is possible to reliably melt even hard ice.
As described above, the present invention provides a compressed snow lump fine / hot water multi-stage jet-melting type snow melting treatment apparatus capable of reliably melting all the snow conveyed from a snowplow or the like.

  In winter, snow removal in regions and regions with a lot of snow is very difficult, and as the era of declining birthrate and aging population, the burden of snow removal work has a profound effect on the daily lives of local communities and residents in an aging society. It is like that. In particular, local governments in prefectures with a lot of snow have a huge amount of snow removal measures, including “snow removal labor costs,” etc., and there are many areas where deficits continue due to those costs. It has also affected the lives of local residents.

In addition, it is necessary to transport the snow piled up on the side road to a large river even after snow removal, and in addition to having to purchase and store an expensive snow removal machine beforehand, There was a problem in the subsequent processing, such as incurring traffic jams during transportation by a transportation truck. In addition, the processing after snow removal is enormously expensive, and troubles on the road and the site are also caused by this snow.
Due to the severe financial difficulties, there are many areas where new development cannot proceed.Therefore, from local governments, etc., the “snow removal labor costs” that account for the majority of the snow removal costs will be reduced, and equipment for melting snow in a short time will be available. The appearance was desired.
In recent years, the means of collecting garbage, etc. installed in sewage has been blocked by snowfall, causing overflow, flooding the road surface, and icing road surface early in the morning. Therefore, there is a tendency to tighten regulations on the disposal of snow in sewage.

Under such circumstances, the present invention has been invented in order to improve such problems. According to the apparatus of the present invention, the snow melting device added to the snowplow on the road can simultaneously melt snow while removing snow with a snow remover, eliminating snow accumulation on the side road after snow removal, eliminating the need for snow accumulation space The advantage is that snow removal for securing public roads and roadside gardens and open spaces, parking lots for large shops, etc. can be performed in a short time reliably by melting snow.
In addition, when the snow piled up after removing snow on the side of the road is a snow removal with high ice quality due to repeated snow melting due to heat and freezing due to cold air, there has been a problem in sufficiently performing the snow melting treatment.

As a known snow melting device, a rotary crushing type snow melting device (Japanese Patent Laid-Open No. 2001-317023) has a burner device at the bottom of a snow melting tank, and has a pair of upper and lower mesh structures that rotate horizontally in the snow melting device. It is assumed that a circular member that reversely reverses is provided, and the ice and snow to be dropped is effectively finely divided to increase the snow melting efficiency.
However, the fine means is a pair of upper and lower horizontal circular members that have a mesh structure and rotate in reverse with each other, and since it has a special structure, it is not expensive and copes with pressing when making shaved ice. However, since there is no such ingenuity, it is likely to be in a state where it is covered with snow on a pair of horizontal circular members, and it is difficult to carry out the fine snowfall processing of ice and snow that can be dropped smoothly. It still left a problem. In this case, there is also a problem that pebbles and the like included in the snow cannot be excluded when removing snow.

Further, a self-propelled snow melting device (Japanese Patent Laid-Open No. 2005-9085) as a known snow melting device is composed of a carriage, an auger housing, and a hot air generating device. It is possible to finely pulverize, melt the finely struck snow with hot air, and efficiently improve the snow melting operation.
However, since melting is caused by hot air, a strong hot air source is required to melt the fine snow with ice only in the case of ice, and a special auger housing is installed, which is expensive. Furthermore, since pebbles and the like included in the snow cannot be excluded at the time of snow removal, there still remains a problem in dealing with these.

Furthermore, a snow melting wheel (Japanese Patent Laid-Open No. 10-292333) equipped with a snow melting stirring blade mechanism melts snow introduced from a hopper by hot air and hot water jets, and further forms a water conduit installed in the snow melting tank. From the rotating shaft and the blades continuously provided in the circumferential direction thereof, hot water is jetted from here to perform the snow melting treatment.
However, in this case, the snow that is melted by the hot air and hot water jet is the snow itself that has been thrown in from the hopper, and in the case of snow that has squeezed snow blocks, pebbles, or built-in snow. Since the snow lump is large, it is stirred by a stirrer while holding the snow lump without being completely melted by hot air or hot water. Because the path for receiving hot air and hot water is short, it remains as a sherbet after stirring with a stirrer that is hot-water treated, and the melting process has problems such as incompleteness. there were.

In view of the above circumstances, the invention of the present application pulverizes the transported snow once into a powder form, which leads to an inclined snowfall sliding guide inclined plate installed below, upstream of the snowfall sliding guide inclined plate In addition, the hot water is jetted at two locations downstream and the snowfall instantaneously melts down to flow down on the snowfall sliding guide inclined plate, and the snowmelt that flows down is accumulated in the hot water storage tank so that further snow melting treatment can be performed inside the hot water storage tank. I have.
In the present invention, a feed roller formed with a pair of steel wires is used as the snow dust processing device, so that the transported snow mass is fine even if it is a snow mass containing pebbles. Since it can be finely processed, even if it is a snow mass containing pebbles with a pair of steel wire surrounding feed rollers with a simple structure, the snow mass can be finely processed while separating the pebbles easily. It is an object of the present invention to provide a compressed snow lump powder / hot water multi-stage injection melting type snow melting processing apparatus (hereinafter abbreviated as “powder / multi-stage melting type snow melting apparatus”).
The present invention promotes the snow melting process by performing the snow melting process in multiple stages at least at two locations upstream and downstream of the inclined plate after the snow lump conveyed from the conventional snowplow has been subjected to the fine powder processing. In order to cope with this, even if there is a possibility that hard ice that is hard to melt snow instantly may be mixed, a hot water injection tube that stirs hot water as a melting means in the hot water tank by means of hot water injection Can be provided. Therefore, even hard ice can be reliably melted by the stirring means that becomes the hot water injection pipe provided in the hot water tank.
The present invention provides a fine and multi-stage melting type snow melting device that can reliably melt the snow conveyed from a snowplow.

The present invention provides a casing provided with a hot water tank in which a hopper for feeding the conveyed snow mass is installed in the upper center and accumulates melted water melted at the lower part, and the hopper is installed in the casing. is to introduce the inserted compacted snow mass in the middle, a pair of rotary brushes acicular rollers the compacted snow masses are implanted in the needle-like member which KonaHoso Te just before the snow melting process is opposed by hot water injection pipe, An inclined plate structure having a slope that accepts powdered falling snow and allows flow downward, and in order to melt the falling snow, in a direction across the flow between the upstream position and the downstream position of the inclined plate It is installed in multiple stages, and hot water is sprayed in the flow direction from the hot water injection pipes installed in multiple stages upstream and downstream, so that in the first stage, the fine snow is melted down on the inclined plate, and each of the subsequent stages In the stage, melt the included snowmelt mass While the hot water injection pipe in a plurality of stages that can flow down on the inclined plate, compacted snow KatamarikoHoso hot water multiple injection melt type snow melt, characterized in that it comprises a heating means for heating the feed water to the hot water injection tube A processing device is provided.

According to the present invention , the above-mentioned pair of rotating brushes installed in the housing following the hopper is used to pulverize the compressed snow mass immediately before the snow melting treatment by the hot water spray pipe, and to form one or more inclined plates. that Ri Na comprises an inclined plate structure, thereby in one slope comprising forming a slope between the upstream position and a downstream position, installed in a direction transverse to the flow of hot water injection pipe in multiple stages, these the hot water injection pipe, in which a basic to melt snow melting by jetting hot water into the direction of flow in each installation position of the multi-stage.
As a variation of the present invention, as a modification of the inclined plate structure having a slope as a long slope, one of the inclined plate structures is formed into a long slope by an inclined plate arranged in a cross-sectional shape and dropped. Snow can be diverted and slopes are formed in a plurality of stages in each downstream direction of the diversion, thereby forming a long slope, and a hot water injection pipe is disposed upstream of each of the multi-stage slopes. One is that the inclined plate structure is formed into a long slope by an inclined plate arranged in a zigzag shape in the housing, and a long slope is formed by a plurality of slopes, and upstream of each stage of the zigzag slope. or disposed hot water injection tube, one still other constitutes the inclined plate structure, the long slope by helical inclined plate to form a helical slope Together, by disposing the hot water injection pipe in multiple stages along the peripheral side surface of the spiral slope, a pressed snow KatamarikoHoso hot water injection melt type snow melting apparatus which enables processing dissolution of the powder light snowfall in multiple stages Also provide.

As an additional attachment device in the inclined plate of the above-mentioned invention, the present invention provides a pair of rubber rollers opposed to each other in the vicinity of the slope end, and an ice piece breaking roller capable of breaking the remaining ice pieces. We also provide a snow-melting processing device for hot-snow lump fine / hot water jet melting.

  Furthermore, the present invention provides, as an additional attachment device in the case of the above-mentioned invention, a third hot water injection pipe connected to the heating means toward the inside of the hot water tank so as to protrude from the hot water tank. A waste accumulation recess is formed in the center of the bottom, and the third hot water jet pipe creates a swirling flow in the hot water bath to promote melting of the snow melt flowing down into the hot water bath, and from the melted snow by centrifugal action due to the swirling flow. Provided is a compacted snow lump fine / hot water jet-melting type snow melting treatment device characterized in that the separated impurities such as pebbles and the like are accumulated and settled in a waste accumulation recess in the center of the water bath and can be separated.

According to the invention related to the compressed snow lump powder / hot water jet melting type snow melting treatment apparatus of the present invention, when the snow lump or human power is used to remove snow, the lump of snow is finely divided. The powder is finely processed into snow, and the finely processed snow is guided along the inclined surface of the inclined plate, and the flow is crossed by the guided fine snow at a plurality of locations upstream and downstream of one inclined plate. By spraying hot water in multiple directions from the hot water injection pipe installed in the direction, the snow can be easily and quickly melted by these simple devices. In this case, the molten water is accumulated in a recovered hot water tank, and a pump and a piping means are provided for recirculating the molten water in the recovered hot water tank to the hot water injection pipe by a heating means separately installed in the fine powder / snow melting apparatus. In particular, the snow block of snow removed conveyed to the bucket hopper is effectively separated and pulverized by a pair of rotating brushes even when pebbles are included, so that the fine snow is quickly and effectively melted. As a result, the snow melting treatment apparatus has an advantage that more complete melting of snow removal can be achieved than in the prior art. Needless to say, it is possible to provide a miniaturized apparatus for manpower work as a complete single isolated snow lump powder / hot water jet-melting type snow melting processing apparatus equipped with a snow melting processing heating means and a water melting circulation means.
The heated water sprayed from the hot water spray pipe was hot water that could melt the snow lump more rapidly. However, it is expensive to install a hot water supply device, and it is cost effective. Therefore, it is not possible to expect remarkable effects economically, and there are few practical advantages. Rather, it is possible to effectively melt snow even in hot water by increasing the slope so that it can receive multiple injections of hot water. It has been found. For this reason, the snow melting processing apparatus according to the present invention need not necessarily be hot water.

  In order to take a long slope formed by the above-mentioned inclined plate as an invention characterized by the form of the inclined plate according to the compressed snow lump fine and hot water multistage jet melting type snow melting processing device of the present invention, one is the inclined plate Are arranged in an umbrella-like cross section so that falling snow can be diverted, and formed as a long slope with a plurality of slopes in each flow direction to be diverted, and a hot water injection pipe is disposed in these multiple slopes, The other is that the inclined plate is arranged in a zigzag shape in the housing to form a long slope by a plurality of slopes, and a hot water injection pipe is disposed at each stage of the zigzag slope. . The other is that the inclined plate is formed as a long slope by a spiral slope, and hot water injection pipes are arranged in multiple stages along the peripheral side surface of the spiral slope. In this way, a long slope is formed by multi-stepping of the slope or spiraling of the slope, and then hot water is sprayed in multiple stages, so that the melting of the fine snow can be melted and melted in multiple stages to enable effective snow melting treatment. Can do.

  In the present invention, an ice piece breaking roller capable of breaking the remaining ice pieces can be installed in the vicinity of the end of the slope as an additional attachment device in the inclined plate of the invention described above. In this case, the ice piece crushing rollers are a pair of rubber elastic rollers, and when ice pieces that could not be melted by the hot water jet on the slope existed, even if they contained pebbles, The ice pieces are easily liquefied by being sandwiched between the elastic rollers under pressure, and are guided to the melt tank after completing the melting process.

  Further, the present invention provides, as an additional attachment device in the case of the above-described invention, a third hot water injection pipe connected to the heating means is provided in the hot water tank so as to protrude into the hot water tank, When a waste accumulation recess is formed at the center bottom, the third hot water injection pipe creates a swirling flow in the hot water bath to promote melting of the melted snow flowing down into the hot water bath, and the centrifugal flow by the swirling flow The accumulated impurities such as pebbles and the like separated from the melted snow by the action can be separated and eliminated effectively by accumulating in the center, so that the contaminated impurities are not mixed in the operating system of the apparatus. This can advantageously eliminate the occurrence of clogging of the hot water injection port, thereby prolonging the life of the apparatus.

  A pair of feed rollers adopts a roller having a steel wire formed on the surface thereof as a means for finely processing a snow lump subjected to snow pressure of the present invention. However, the present invention is not limited to this, and a small snow melting machine for home use. In this case, since it is required to be more inexpensive, it is possible to select and produce a scouring needle-shaped material. As the structure of the roller surface on which the needle-like member is implanted, the needle implantation density may be uniform, but the surface has a shallow groove such as a spiral or zigzag, or a groove whose depth decreases in the rotational direction. It is also possible to provide a devised groove, which makes it possible to more easily and smoothly perform the fine snow lapping process even when pebbles or hard ice blocks are included.

  Although the embodiment has been shown in which the snow melting processing apparatus is pulled by a snowplow, it can be a rear car type small human powered traveling type.

In the present invention, especially when the snow melt of snow is repeated in the springtime, the snow heap contains a lot of ice pieces, but even when the snow heap containing a lot of ice pieces is removed, it is conveyed. In order to make the melted snow melt effective, an ice piece crushing roller capable of crushing the remaining ice pieces can be installed near the end of the slope. Is. In the processing by the ice piece crushing roller, the ice piece crushing roller becomes a pair of rubber elastic rollers, and the ice pieces that could not be melted by the first hot water jet in the flow process on the slope are long. Since ice pieces are sherbeted by hot water jets in multiple stages while flowing down the slope, they are easily liquefied when sandwiched under pressure between elastic rollers in the final stage, so that the melting process is complete. Can do.
Regarding the installation of the ice piece crushing roller, in the case of a spiral slope, since the flow path can be taken particularly long, the ice pieces can be almost completely melted during the flow of the long slope injected with multi-stage hot water. The installation of the ice piece crushing roller can be omitted.

FIG. 1 schematically shows a snowplow L that uses the fine and multistage melting type snow melting device S of the present invention in a pullable manner. Here, FIG. 1A shows a schematic diagram viewed from the side, and FIG. 1B shows a schematic diagram viewed on a plane.
In FIG. 1, the fine and multi-stage melting type snow melting apparatus S of the present invention includes a casing 8 that is connected to a snowplow L by a coupler J so as to be towable, and that has a hot water tank 9 that accumulates molten water inside. The hot water tank 9 has a hopper 1 that receives snow removal at the upper end.
When a snowplow L such as a shovel loader that is generally used here proceeds, the snow is moved and gathered downward by the inclined curved excavator A, and is guided to slide up on the conveyor B adjacent to the side. . Further, the snow pushed up as the snowplow L moves is put on a multi-stage conveyor B and conveyed to a snow feed guide C, and finally, the fine and multi-stage melting type snow melting apparatus of the present invention. It is put into the S hopper 1.

FIG. 2 relates to the fine / multi-stage melting type snow melting apparatus S of FIG. 1, and is a cross-section of the fine / multi-stage melting type snow melting apparatus S of the present invention as seen along the arrow AA in FIG. It is a schematic diagram, and is a diagram for mainly explaining a drive device according to the fine / multi-stage melting type snow melting device S.
In FIG. 2 (b), the fine and multi-stage melting type snow melting device S includes a rotating brush 2 for fine snow lump comprising a pair of rollers 2a and 2a in which needle-like members are implanted, and a drive mechanism 7 thereof. , Motor 7a, belt 7b, pulley 7c, gear 7d and the like. The rotary brush 2 is arranged on the inner box-type hot water tank 9 of the fine and multi-stage melting type snow melting device S, facing the outlet of the hopper 1, and each of the parts constituting the brush rotation driving mechanism 7 is a powder It is installed in a space (a space on the left side in the direction of travel in the drawing) between the outer casing 8 and the hot water bath 9 of the thin / multi-stage melting snow melting device S. Accordingly, the rotation of the motor 7a is transmitted to the meshing gear 7d via the belt 7b, and is transmitted to each meshing gear via the belt 7f to the passive wheel of the rotary brush 2, and the needle-like member is implanted. The pair of rollers 2a and 2a are rotationally driven.
As shown in FIG. 3, the pair of rollers 2 a and 2 a in which the needle-like members constituting the rotating brush 2 are implanted have needle-like members implanted on the surfaces of the rollers. The compressed snow mass conveyed between the pair of rollers is pulverized by a needle-like member on the roller surface. Although not shown in the arrangement structure of the pair of rollers 2a, 2a, it is also possible to adopt a structure in which the roller interval can be adjusted so as to be executed finely and smoothly by the snow quality.

Next, according to FIG. 4, the processing state of the pressed snow mass introduced from the hopper 1 will be described.
The processing mechanism includes the following devices.
The snow melting device S has a double box structure of an outer casing 8 and a box-shaped hot water tank 9 provided on the inner side, and is installed separately at the bottom of both by interposition of a spacer. In the center of the bottom of the hot water tank 9, a recess 9a that protrudes further downward from the bottom of the housing 8 is formed, and the recess 9a constitutes a waste storage part as will be described later.
Further, as a side space of the casing 8 and the hot water tank 9 box body, heating means 12 including a gas cylinder 12a and an instantaneous water heater 12b is installed in the front side space, and a pair of rollers as described above is installed in the side space. A brush rotation drive mechanism 7 for driving 2a, 2a is provided. Behind the hot water tank 9, it is partitioned into a recovered hot water tank 10 and a drain tank 11 by partition plates 9c and 9d, respectively. Since the lower part of the partition plate 9c is opened and both chambers are communicated, the hot water tank 9 and the recovered hot water tank 10 are held at the same water level, while the partition plate 9d is provided with an overflow mechanism such as an overflow port. Above the predetermined water level, water is drained from the recovered hot water tank 10 to the drainage tank 11. The recovered hot water tank 10 is provided with a circulating water supply means 14 including a submersible pump 14a and a pipe 14b.
A pair of rollers 2 a and 2 a in which needle-like members constituting the rotating brush 2 are implanted are installed below the hopper 1 inside the hot water tank 9 in which the hopper 1 is installed at the top. An expansion scattering prevention plate 6 is installed and formed so as to contact the lower part of the roller rollers 2a and 2a and to cover the inner space so as to go obliquely downward. As shown in the figure, a part of the expansion scattering prevention plate 6 can be supported by the second hot water jet pipe 3b. The first hot water spray pipe 3a is located on the lower inner side of the enlarged scattering prevention plate 6 so that the snow that has been finely processed by the rotating brush 2 is not scattered on the first hot water spray pipe 3a. 4 installed while being protected by
An umbrella-shaped inclined plate 5 is installed in contact with the lower part of the first hot water injection pipe 3a, and the snow on the inclined plate 5 is further melted by the hot water from the first hot water injection pipe 3a, so that the upper surface of the inclined plate 5 is smooth. It is possible to flow down. At that time, since a small and high weir is formed at the downstream end of the inclined plate 5, the amount of water flowing is always ensured on the surface, so that smooth flow is guaranteed.
The hot water tank 9 inside the housing forms a hot water tank 9 that stores the snowmelt water that has fallen in temperature that flows down on the inner inclined plate 5. At the bottom of the hot water tank 9, there is a contrivance that feeds hot water from the instantaneous water heater 12 b into the hot water tank 9 to create a rotating vortex of hot water in the hot water tank 9.
The second hot water injection pipe 3b that can support the expansion scattering prevention plate 6 melts the snow on the inclined plate 5 by the hot water from the first hot water injection pipe 3a, and the downstream of the molten water that flows down. Hot water is jetted onto the portion from the second hot water jet pipe 3b, thereby further ensuring snow melting.

The melt processing mechanism by the fine / multi-stage melting type snow melting apparatus S will be described above.
A compacted snow mass is charged from the hopper 1 of the snow charging port of the fine and multi-stage melting type snow melting device S. The thrown snow blocks are finely pulverized by the rotation of the needle rollers 2a and 2a of the rotating brush 2, and are dispersed while being guided by the enlarged scattering prevention plate 6 and scattered downward. The finely divided snow dispersed on the inclined plate 5 is instantly melted by the hot water ejected from the ejection port of the first hot water fountain pipe 3a. Also, a “warm river” is made with warm water flowing on the inclined plate 5, and the snow dropped thereon is simultaneously melted almost instantaneously by the warm water discharged from the warm water fountain pipe 3 a.
Furthermore, the device which melt | dissolves instantly again with the warm water ejected from the injection port of the 2nd warm water fountain pipe 3b in the downstream of the inclination board 4 is made | formed. Accordingly, the “warm river” is reconstructed with warm water, and the snow dropped on it is also melted almost instantaneously by the warm water discharged from the warm water fountain pipe 3b.

The melted “warm river” flows down from the inclined plate 5 and is stored in the hot water bath 9. The hot water stored in the hot water tank 9 passes under the partition plate 9c and also enters the adjacent recovered hot water tank 10. Hot water that has entered the recovered hot water tank 10 is sucked up by the submersible pump 14a, travels through the pipe 14b, and is sent to the instantaneous water heater 12b. The water (low temperature hot water) sent to the instantaneous water heater 12b is heated by the gas supplied from the gas cylinder 12a, and the heated hot water sequentially passes through the pipes P1, P2, P3 to the hot water fountain pipes 3a, 3b, 3c. The warm water fountain tubes 3a, 3b, 3c are sprayed with warm water and used for melting snow.
The pipes P1 and P2 are connected to the hot water fountain pipes 3a; 3a, 3b; 3b by individual pipes, and the individual pipes are individually connected to the hot water fountain pipes 3a, 3a depending on the pipe distance. It is devised so that the injection amount does not become uneven.
As described above, the hot water ejected from the hot water fountain tubes 3a, 3b, 3c is supplied by heating the hot water accumulated in the hot water tank 9 by the instantaneous water heater 12b, and is always circulated and used.
The hot water injection pipes 3a, 3b, 3c are installed in a direction crossing the flow, and the fine snow flowing through the slope of the inclined plate from the hot water injection ports of the hot water injection pipes 3a, 3b, 3c is melted. It is injected in the direction of flow above the flow.
By installing the hot water injection pipe in the direction crossing the flow, the fine snow on the slope of the inclined plate can be uniformly injected into the flowing flow while melting, and the injection direction is also pushed in the direction along the flow By spraying in this manner, the flow is promoted and a smooth flow is formed, so that the snow melting treatment while flowing can be efficiently performed.

  The hot water stored in the hot water tank 9 is discharged from an overflow port formed as a constant water level drain port of the partition plate 9d when the snow melts and water (low temperature hot water) increases after a certain amount accumulates. The water is stored in the drain tank 11. The stored water in the drainage tank 11 is discharged from the drainage port 11a by opening a drain valve (not shown) or the like.

Moreover, a part of the hot water sent from the instantaneous water heater 12b can be sent to the hot water tank 9 through the pipe P3, and a hot water vortex can be created in the hot water tank 9. Due to the generation of the rotating vortex, the ice that is relatively difficult to melt is melted in a short time, so that it is possible to further promote the melting of the ice.
As described above, recirculating hot water (or hot water) while making warm water (or hot water) with these series of systems, and melting the snow that has been made into a powder and easily melted with the hot water, so that the compacted snow block that is thrown from the hopper Can be melted in a large amount in a short time, and a more efficient snow melting device can be provided.

  It should be noted that small stones and dust that are thought to enter the snow so far may interfere with the hot water circulation function. However, due to the formation of the rotating vortex by the third hot water fountain tube 3c described above, Since it can be collected in the waste accumulation recess 9a at the center of the bottom and discharged from the discharge port 9b after the work is completed, it is possible to avoid the possibility of hindering the hot water circulation function due to small stones or dust. .

  The present invention is schematically shown in FIG. 6 as having an umbrella-type multistage slope. As shown in FIG. 6, following the inclined plate 5 which is stacked below the uppermost protective cover 4 with a gap, an inclined plate 5 which is stacked with a gap below is disposed. A long slope 5A is formed by the multi-stage arrangement. The hot water spray pipe 3 is disposed in an overlapping portion having a space between the inclined plate 5 and the inclined plate 5. According to this, the finely processed snow is diverted to both sides by the protective cover 4 and flows along the inclined plates on each side of the multi-stage umbrella-shaped slope 5A. Therefore, the fine snow flows down in the multistage umbrella-shaped slope 5A while being melted by the hot water jet from the hot water jet pipe 3, and the melting process by the hot water jet is performed in multiple stages. Thereby, the melting of fine snow can be completed.

In this embodiment, as shown in FIG. 6, an ice piece breaking roller 15 can be installed near the end of the slope 5A. The ice piece breaking roller 15 is composed of a pair of rubber elastic rollers. When there is an ice piece that could not be melted by the hot water jet on the slope, even if it contains pebbles, the ice piece can be securely held between the elastic rollers under pressure. Thus, by biting the ice piece crushing roller 15 immediately before flowing into the hot water bath 9, even if it contains residual ice pieces, it can be easily liquefied. Therefore, it is possible to further promote the melting process of the pressure snow mass during the snow removal of the roadside heavy snow.

  The present invention is schematically shown in FIG. 7 as having a zigzag multistage slope. As shown in FIG. 7, the inclined plate 5 includes an inclined plate that is inclined downward toward the lower left, an inclined plate that is subsequently inclined downward toward the lower right, and an inclined plate that is subsequently inclined downward toward the lower left. A long slope is formed as the zigzag multistage slope 5B by the zigzag multistage arrangement of the inclined plates. Therefore, the hot water spray pipe 3 protected by the protective cover 4 is disposed at the upper part of each inclined plate 5. According to this, the fine snow falling on the inclined plate is received by the inclined plate and flows down while being melted by the hot water injection from the hot water injection pipe 3. The snowmelt water flows along the zigzag multi-stage slope 5B. Also in this embodiment, since the fine snow is melted by hot water injection in multiple stages in the zigzag multi-stage slope 5B, further melting of the fine snow can be achieved.

Also in this embodiment, as shown in FIG. 7, the ice piece breaking roller 15 is installed in the vicinity of the end of the slope 5B. The operation and effect of the ice piece breaking roller 15 are the same as in the above embodiment.

The present invention is schematically shown in FIG. 8 as having a spiral slope 5C.
The central portion of the spiral slope 5C is attached to and supported by the slope support 5Cp, and the outer periphery thereof is provided with a spiral peripheral side wall 5Cw and is supported by the slope tower 5Ct. An appropriate number of hot water injection pipes 3 are provided through the spiral peripheral side wall 5Cw in a direction crossing the flow on the slope.
As shown in FIG. 8, a long slope is formed by forming, as a spiral slope 5 </ b> C, an inclined plate that receives the fine snow processed by the rotating brush 2 and guides it to flow down. Here, in the spiral slope 5 </ b> C, a plurality of hot water injection pipes are appropriately installed across from the vicinity of the upper part to the vicinity of the lower part. As a result, the hot water is sprayed on the fine snow that has been processed by the rotary brush 2 by the hot water jet tube 3 and received in the spiral slope 5C to melt the fine snow, thereby enabling multi-stage snow melting treatment. Even in the case of the spiral slope 5C, the complete melting of the fine snow can be further promoted as in the previous embodiment.
FIG. 9 is a diagram schematically showing the arrangement of the spiral slope and the hot water injection pipe.
