Analysis of Snow Clearing Methods
In the past, the snow-clearing method in our country was relatively primitive, mainly relying on manpower, using shovels and brooms to clear the snow.
This method not only wastes a lot of manpower and material resources but also has low snow-clearing efficiency. Snow is more difficult to remove when compacted by vehicles.
Therefore, it is imperative to find a snow-clearing method that has both higher efficiency and lower cost.
At present, the snow removal methods commonly used in various countries are two basic methods: mechanical snow removal method and snow melting method. The mechanical snow removal method is a method to remove the hazards of ice and snow through the direct action of machinery on ice and snow.
Snow cover can be divided into three types according to the state:
(1) Loose snow, that is, snow that has not been crushed by people and vehicles after the snowfall, is loose in texture; large in size, and good in fluidity;
(2) Compacted snow, that is, the mixture of ice and snow formed by people stepping on and vehicles pressing after the snowfall, has different degrees of hard layers and is not easy to remove;
(3) The ice layer is snow that melts into the water due to sun exposure or vehicle rolling and then freezes into ice. In addition to water, there is a lot of dust and sand in the ice layer, which is hard in texture and firmly bonded to the ground.
Therefore, snow removal machinery includes two types: snow blower and deicer.
Introduction of Mechanical Snow Removal Equipment
According to different working principles, snow blowers can be divided into three types: pushing type, snow throwing type, and snow blowing type.
The push-type snow plow is to install snow plow blades, snow plows, and other devices on bulldozers or other vehicles to push the snow away, open the channel, and then use the truck to transport the snow away.
This method can only push the snow to the side of the road, does not have the ability to collect snow, and is only suitable for fresh snow or crushed compacted snow, which has low efficiency and is easy to scratch the ground.
The snow-throwing machine is equipped with a snow-blowing pump to throw the collected snow to the side of the road or into the transport vehicle.
Among them, the spiral type is the most common. Snow-blowing snow blowers are generally equipped with aero engines, which generate a powerful high-pressure airflow to blow off the snow on the ground through the nozzle.
The snow-blowing type snow blower runs at a high speed and has high productivity, but it is only suitable for fresh snow and can only be used in airports, bridges, and highways. The cost is high and it is not suitable for the development of small products.
From the comparison and analysis of the above two main snow removal methods, we conclude that mechanical snow removal should be the main method.
Purpose and Significance of Research on Mechanical Snow Removal Equipment
In Northeast, my country, North China, and parts of Northeast Inner Mongolia, snow and ice accumulation in winter often cause serious traffic obstacles. In some road sections such as ramps, turns, intersections, airport runways, etc., there are snow and ice accumulations on the road surface. Then the impact is more serious, often causing traffic accidents.
Snowfall in winter brings a lot of inconvenience to people’s travel on the road. The traditional artificial snow removal method is labor-intensive and low in efficiency. Northern cities often use professional large-scale snow removal machines to remove snow, but due to their high purchase and use costs and wide working width, they are often only suitable for cleaning urban roads.
Research Status of Mechanical Snow Removal Equipment at Home and Abroad
The use of mechanical snow removal is the best way to liberate people from the heavy snow removal work, and greatly improves the efficiency and speed of snow removal. Therefore, scientific workers have been exploring how to develop safe, reliable, and practical snow removal machinery.
In foreign countries, the initial snow removal machinery used bulldozers or loaders to gather snow together with its bulldozer blades and loading buckets, which later developed into plow snow removers.
As early as 1943, Japan began to install V-shaped plows on trucks for snow removal. After years of development, foreign plow-type snow removers have reached a relatively high technical level.
After the appearance of the plow snow plow, rods made of synthetic materials pointing to different directions of the circumference appeared on the drum as special equipment for snow removal, but it was only effective for snow that was not frozen until the continuous snow plow appeared later. Clearing snow is only a matter of time after the fast, large rotary snow blower.
Rotary snow blowers generally have the functions of cutting, concentrating, pushing, and throwing, and have the characteristics of complex structure and multiple functions. Russia and Japan are the main countries producing rotary snowblowers with mature technologies. Its product performance is at the leading level in the world.
Snow plows have been developed abroad for decades, especially in Scandinavian countries such as Sweden and Finland.
According to my country’s national conditions, domestic research on the mechanical properties of snow should be strengthened and a road meteorological system should be established. Snow removal machinery should develop in the direction of miniaturization and high speed, and develop in the direction of multi-function and electromechanical integration. At the same time, attention should be paid to improving safety and comfort. sex.
Summarize
In short, compared with other types of snow removal machinery, snow throwing snow removal machines generally have the functions of cutting, concentrating, pushing and throwing snow. It is widely used and is a modern and efficient snow-removal machine.
