Abstract

<P>PROBLEM TO BE SOLVED: To create a non-slippery road surface after mechanically scraping ice away from the road surface. <P>SOLUTION: The surface of the ice covering the road surface is scraped by turning an ice scraping blade 9. Water sent from a spraying device 4 is turned to be mist and sprayed to the road surface by a jet orifice 8 to wet the road surface so that scraped particles and broken pieces of ice may be re-attached to the road surface by nature that the water is frozen below a freezing point. A springboard 5 is provided in advance at the rear side of the scraping blade 9 contacting with the road surface. The jet orifice 8 is provided on the reverse side of the springboard 5. Since a small space is formed between the road surface and the springboard 5, which is not obstructed by the particles and broken pieces of ice, the road surface is evenly made wet when the mist is sprayed to the road surface from the jet orifice 8 utilizing the small space. When an ice scraping machine is advanced, the road surface wet with the water is covered by the particles and broken pieces of ice to have a belt-like state. When exposed to the outside air below the freezing point, the water on the surface is frozen on the road surface in a short time, and the harder, rougher and non-slippery road surface can be created. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention covers the road surface in order to prevent such an accident because the snow covering the road surface is crushed into ice in the winter season and becomes an ice, and there are many accidents that fall on frozen roads that slide slippery. The surface of the ice is scraped mechanically with a rotating ice cutting blade, scratches the road surface, and the scraped and scattered ice particles and debris are re-adhered to the road surface, resulting in countless rough texture on the road surface. It is related with the ice machine which prevents a pedestrian from falling by creating.

  In northern countries where the cold is severe, pedestrians fall frequently because the road surface slips slippery due to snow pressure and ice-burning during the winter. To prevent such accidents, Non-slip sand is sprinkled around the entrance of the facility, which is effective immediately after spraying, but when exposed to sunlight in the daytime, the sand becomes easy to melt and the sand sinks. However, the anti-slip effect will fade, and eventually it will completely lose its effect in a few days, so we had to re-spread the sand again. In the early spring, roads and sidewalks are full of sand, and the wind blows up and adversely affects your health.Sand spraying involves the cost of purchase, and it also costs money to process the sprayed sand. It takes me In the present situation is the reality that the sand is not unmanageable cease without any good way to another has been sprayed.

  The application of sand to prevent a fall accident has many problems with adverse effects on the environment and human body, so the present invention does not prevent the fall by spreading sand on the ice covering the road surface. Without mechanically scraping the surface of the ice covering the frozen road surface, scratching the road surface, and using the ice particles and debris that are scraped and scattered as a substitute for sand, the ice smasher is engine (1) The rotating ice cutting blade (9) and the spraying device (4) are combined to form a single unit, and the function is demonstrated. In addition, as shown in the figure, the ice machine is moved. The pedestal is a sled (7), so you can move forward and backward by pushing and pulling the handle (3) for operation. If you let it go, move forward while scraping the road surface If you step in this state, the ice particles and debris will act like a lubricating oil, making it more slippery and inducing a larger fall accident. From this fact, the present invention uses the principle that water freezes below freezing point, and attaches these very troublesome ice particles and fragments to the road surface to create a rough road surface. In order to make it possible, water is sprayed on the surface of the road surface that has been scraped off by the rotating ice cutting blade (9), while splashed ice particles and fragments cover the rotating ice cutting blade (9) (6 ), Falling while colliding, and laying down on the road surface after moving the ice machine, the water freezes below freezing point and acts as an adhesive, so ice particles and debris are removed from the road surface. Can be firmly adhered to We create a non-slip state of the road surface of the feeling that was so, we can to prevent the fall accident of pedestrians.

Problems to be solved by the invention

  Using the principle that water freezes below freezing point, the ice machine must be operated at a temperature below the freezing point in order to bond the scraped ice particles and debris to the road surface. The water used will freeze in the device and may damage the device, so the water used must be warmed and warmed up. It takes time and can melt ice particles and debris, making the surface smooth and unreasonable to create a rough road surface, the amount of water used must be kept to a minimum, Furthermore, when the ice on the road surface is shaved with the rotating ice cutting blade (9), the ice particles scatter back, but these ice particles are contained in the cover (6) covering the ice cutting blade (9). It ’s going to be laid down, In order for the particles to adhere to the road surface, the road surface must be wetted with water just before the ice particles are spread on the road surface, but the ice particles that collide violently in the cover (6) It is very difficult to efficiently wet the road surface to prevent watering.

Means for solving the problem

  To create a slippery road surface, the ice cutting blade (9) that rotates with the power of the engine (1) is moved forward while lightly touching the frozen road surface to scrape the ice surface that covers the road surface. When (9) touches the ice surface of the road surface, the ice particles instantly scatter backwards, and the ice particles are laid down on the road surface while violently colliding in the cover (6) covering the ice cutting blade (9). In order for the ice particles to adhere to the road surface, the road surface must be wetted just before the ice particles are spread, but the water collides violently in the cover (6) In order to make it possible to wet the road surface because it is obstructed by the ice particles, the present invention has a structure in which the rear part of the ice cutting blade (9) is in contact with the road surface as shown in FIG. A jumping board that soars the ice particles ) Is provided at an angle. This creates a small space between the road surface and the jump plate (5) that is not obstructed by the scattered ice particles and debris. An injection port (8) is provided on the back side, and water sent from the spray device (4) is sprayed onto the road surface. By spraying mist in this way, the road surface can be efficiently wetted with a minimum amount of water. Because the ice particles and debris are spread in a band on the road surface after moving the ice cutter, the water freezes in the outside air below the freezing point and works as an adhesive in a short time. Because it freezes on the road surface, you can create a rough and slippery road surface.

The invention's effect

  When the effects of the invention are arranged in bullets, the following four items can be summarized:

  (1) It is harmless to the environment and human body because it uses ice particles and debris instead of spraying sand.

  (2) Free from the cost of purchasing sand and the troublesome work of processing used sand.

  (3) The mist sprayed from the back of the jumping plate (5) is sprayed directly onto the road surface without being disturbed by ice particles, so that the road surface can be efficiently wet without unevenness.

  (4) Since the road surface can be wetted with a minimum amount of water, ice particles and debris can be adhered to the road surface in a short time.

  The ice grinder is equipped with a sled (7) as a means of movement, so it can be moved forward and backward by applying force to the handle (3). The ice grinder (9) has a sled (7 ) If you rotate it slightly lower than the bottom position, you can easily scrape off the surface of the ice covering the road surface, the ice particles scraped at this time will scatter to the rear of the ice blade (9), The board is soared by the slanting board (5), so there is a small space between the road surface and the board (5) that is not disturbed by the scattered ice particles. ) Is sprayed from the spraying device (4) through the spray port (8) provided on the back surface, so that the water is sprayed onto the road surface as a mist. The road surface is evenly wetted with water, and immediately after that ice particles and debris It will be covered with The road surface wet with water by the outside air and the spread ice particles and fragments are firmly joined in a short time, and the road surface becomes rough and slippery. It is more effective if it is performed from the evening when the cold gets severe to the next morning.

  The winter roads in the northern country have a lot of snow, so there is no way to distinguish between sidewalks and roadways. Pedestrians have to walk along the roadways. It will be easy, and accidents falling on the roadway will continue, and at the entrances and exits of busy walkways and supermarkets, it will be in the same state, especially for elderly people with weak legs and legs People with disabilities have difficulty walking and hesitate to go outside. The rough road surface created by operating the ice hoist of the present invention is safe for everyone without fear. You can walk, and you can ease the flow of the car that slips and gets stuck by taking the same measures on the roadway such as uphill by increasing the size of the ice machine. It is.
