DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled direct heat snow melting apparatus for snow removal and snow melting on a road mainly in a snowy cold region.

[0002]

2. Description of the Related Art Roads in winter in snowy and cold regions are used to remove snow by mechanical power such as a bulldozer, to prevent deicing by spraying deicing agents and mixing with pavement materials, and to prevent snow from melting in order to ensure smooth traffic and safety. Various road surface measures are taken, such as snow melting by spraying or road heating, grooving to form grooves on the road surface, and slip prevention by spraying a non-slip agent.

[0003] In particular, snow removal is an essential measure in winter road surface management, but in mountainous areas and plains, snow removed by a rotary-type snowplow blows off the road, so there is not much obstacle to traffic. However, there is no place to easily dump snow on roads such as urban areas and densely populated houses, so there is no choice but to accumulate on sidewalks and roadsides.

[0004] For this reason, the sidewalk is not used because of the accumulated snow, and the width of the roadway becomes narrow, which causes a traffic obstruction, and the function as a road is remarkably impaired. The accumulated snow is loaded onto vehicles such as trucks and dump trucks by excavators and transported to dumping places such as suburban open spaces, but the operating mechanical power is limited,
In addition, they are often left unattended for many days due to lack of dumping sites and saturation in urbanization.

[0005] For these reasons, in recent years, snow melting facilities such as road heating and snow melting tanks at an individual pace, and facilities such as snow ditch on a regional basis have been installed in recent years. Due to restrictions on installation conditions, it has not yet become widespread.

As described above, snow removal is indispensable for maintaining the function of the road, but treatment of accumulated snow is also an essential requirement. If a system for immediate removal of snow is in place, no accumulation will occur, which is desirable.However, if snowfall continues for many days or heavy snow falls, snow removal must be given top priority, and there is no accumulation of snow. It is impossible at present to do so. Recently, as a means for solving such a problem, a snow melting vehicle loaded with a device that performs snow melting processing on the spot while moving snow removed or accumulated snow has been developed and started to operate.

[0007]

However, the conventional snow melting vehicle has the following problems. B.Because it is a large vehicle with a total vehicle length of 10m or more, a total width of about 2.5m, and a minimum turning radius of 10m or more, it cannot enter narrow roads such as residential areas where there is no place for dumping snow. It can only operate on wide main roads. (B) Since it is manufactured as a snow melting car, the manufacturing cost is high and it cannot be used for other purposes. Further, it is difficult to easily cope with an increase or decrease in the size of the vehicle and the snow melting ability desired according to the local road environment.

C. A system in which only a snow melting device is mounted on a vehicle, and snow removed or accumulated by a rotary snow plow or the like is thrown into a vehicle equipped with a snow melting device to melt snow has been developed. Requires a minimum of 10 people to work with a rotary snowplow, etc. and a vehicle equipped with a snow melting device always running side by side, for traffic regulation of operating vehicles and guidance and work of snow removing vehicles and snow melting vehicles. As a result, human efficiency is low and work is performed using two vehicles, resulting in an increase in work cost.

D. For example, the self-propelled snow melting apparatus disclosed in Japanese Utility Model Publication No. 6-21937 passes hot air from a burner through a flue, heats water in a water chamber while passing through the flue, and ejects the water from a pipe. Because it melts the snow in the snowmelt tank with hot steam, the structure is complicated, and eventually the equipment becomes large, and it can not be loaded unless it is a large vehicle, so it can not be loaded on narrow roads such as residential areas where there is no place for dumping snow. The fact is that they cannot enter, and can only operate on arterial roads with wide lanes.

The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent a road function from being paralyzed by snow accumulated on a sidewalk or a road side portion due to snow removal. It is possible to remove snow on the road or collect and collect snow accumulated on the roadside with one vehicle, and at the same time, perform snow melting on the spot.
Even in a narrow road having width not possible with prior art, have operable maneuverability, and reduce the work cost by reducing the personnel of the work, and the period other than winter It is an object of the present invention to provide a self-propelled direct heat melting apparatus that can be used for other purposes.

[0011]

The scattered particles 17 are melted by contact with the high-temperature hot air rising from the lower part of the snowmelt tank 17, a part of which evaporates as water vapor, and the other falls as a water drop naturally . At that time, the chain
Due to the centrifugal force caused by the rotation of 19,
The airspace in the snowmelt tank 17 increases, and the hot air
Because it is diffused into the snowmelt tank 17, it comes into contact with the high-temperature hot air of snow.
Tactile increases. The fallen snowmelt water is collected from the bottom of the snowmelt tank 17 through a pipe 28 into a snowmelt water tank 29 as a drainage device. Further, the high-temperature hot air melts the snow while rising in the snow melting tank 17 due to a draft effect and a pressure difference due to a difference between the temperature in the snow melting tank 17 and the outside air temperature, and is cooled to a low temperature to the outside through the exhaust port 30 above the snow melting tank 17. Exhausted.

The inside of the snow melting water tank 29 is partitioned by a wire net 31 so that foreign matters such as pebbles and gravel mixed in the snow can be removed. A pipe 32 is provided.

And On the other hand, the combustion burner 27
Since the high-temperature hot air is blown into the snow melting tank 17 by the snow has been Oite crushed scattered in snow melting tank 17
During that time it is melted.

The snowmelt water melted inside the snowmelt tank 17 falls naturally as water droplets, and partly evaporates as water vapor.
The snowmelt water is collected in a snowmelt water tank 29 from the bottom of the snowmelt tank 17 through a pipe 28. In addition, water vapor is supplied to the snow melting tank 17.
Due to the draft effect and the pressure difference caused by the difference between the inside temperature and the outside air temperature, the snow melts while rising in the snow melting tank 17, and is cooled to a low temperature and exhausted to the outside from the exhaust port 30 above the snow melting tank 17. Foreign matter such as pebbles and gravel mixed in the snowmelt water collected inside the snowmelt water tank 29 is removed by a wire net 31. The snowmelt water is sucked from a drain pipe 32 by a drain pump 33, and a drain hose connection port 34 is provided. The water is drained to drainage channels and the like.

As described above, while traveling on the road, the snow on the road or the like or the snow accumulated on the sidewalk or the side of the road can be collected and, at the same time, snow melting can be performed on the spot. Of course, snow melting can be performed on a narrow road, which is impossible with the conventional technology, as long as the vehicle can enter the road.

In the above embodiment, the snow melting tank 1
Although the description has been given of the case of the base, the number of the snow melting tanks may be two or more, and the capacity of the snow melting tank can be appropriately selected. It is possible to prepare an optimal snow melting tank according to road conditions in a desired area by serializing the tank in accordance with the processing capacity and producing it in a factory.

Further, in the above embodiment, the present invention can accomplish a series of snow processing operations, but can also be used for the following applications due to the structure of the crushing device of the present invention. For example, in recent years, attempts have been made to grind shells such as scallops and mix them into asphalt for road pavement to extend the life of asphalt by the calcium content in the shells. Even if it is crushed, it becomes difficult to use it for asphalt mixing because the shape becomes a flake shape with corners. However, the shell pulverized by the apparatus of the present invention has a substantially round shape with no corners, and thus can be used for pulverizing shells.

[0034]

As described above, according to the present invention, it is possible to simultaneously perform the snow removal, which is essential for maintaining the function of the road in a snowy cold region, and the melting of snow on the spot at the same time. No snow is accumulated in the area, which can cause injuries and traffic obstacles, as well as eliminate the need for transportation to snow dumping sites and reduce the number of people involved in processing. This will greatly reduce road maintenance and snow disposal costs in winter.
Also, Choi as grinding apparatus provided with a crusher to melting snow bath
Scatter the snow while crushing it
In this way, the snow stays longer in the snow melting tank, and the hot air from the combustion burner is blown directly to melt the snow by direct heat. Can be. Therefore, it is possible to modify and use a normal small work vehicle, and it is possible to provide a snow melting device that can be turned around easily. When a small vehicle is equipped with the snow melting device of the present invention, its mobility and direct-heating type snow melting method enable efficient and quick snow melting processing, and can be operated by one person, saving labor. In addition to this, it has an effect that is particularly useful for snow removal on narrow roads. Furthermore, since it has a simple structure and can be easily attached to and detached from the vehicle, it can be used as a general vehicle except during the winter snow treatment period. It can be used for various purposes by attaching various attachments prepared by the manufacturer, so that there is an advantage that the downtime of the vehicle itself is eliminated throughout the year, and the operation rate of the vehicle is greatly improved.
