Snowplow working principle and classification

   Depending on the way the snow removal , snow removal machines can be divided into brush snow throwers , snow throwers and throw Jan plow snowplow in three ways:
A brush snow throwers
    Brush snow throwers known as plows, as shown on the left , it is the use of gasoline powered device drivers and other mixtures of nylon wire brush to make high-speed rotation , thereby cleaning the road surface snow to the side of the road machinery and equipment . Because of this mechanical way of working with our everyday life sweeping the same way , so usually we prefer to call this brush snow throwers for the snowplow .
    Advantage: Even if uneven ground , can also be obtained using this snowplow ground without snow cleaning effect.
    Disadvantages: This only applies to residual snow plow snow cleanup thinner snow snowplow or other work, clean up the thick snow or no snow barrier function.
Young throwing two snow throwers
    Young throwing snow throwers , also known as Young throwing snow or snow machine , it is the use of high-speed rotating blades powered device drivers , such as gasoline or auger and blades , which will snow on the road surface from further involvement in the internal mechanical polishing snow cylinder high-speed side of the road green belt thrown into the machinery and equipment.
    The maximum distance thrown and vary with different engine power , power throwing snow thrown furthest distance of up to about 15-20 meters and a height of about 3 meters.
    Can be remote adjustable for throwing snow throwing distance and angle the same snow machines , the minimum edge distance of about 0.2 m throw Shido .
    Because of this high-speed machinery is to throw the snow to the sides of the road Yang , so we used to call Young throwing snow or snow machine .
    Advantages: 1 can be thrown into the trunk of snow or green belt , avoiding the removal and transport of secondary road side snow ;
    2 has obvious advantages when clearing snow and thick snow barrier. Even compacted snow can be cleared.
    Disadvantages: one can not clear ice on the road . 2 For the potholed roads of snow during the depression can not be cleared .
Three plow snowplow
    Plow snow machine , also known as snow machines, working device is usually installed in front of the host, all the snow machines the most widely used , the origin of the earliest snow removal equipment , mainly used in the new drop compacted snow , snow thickness in more than 30mm . Moldboard with integral , segmented , there are V -shaped and U -shaped plow plow points. Its structure is characterized by : the majority of a dual rocker mechanism , avoid obvious effect, obstacle height greater environmental adaptability, can work in hard snow area. About moldboard angle adjustable , controllable ground clearance to facilitate the operation and shift library use . Some also increased wheel slip boots or other devices to reduce or eliminate the shovel blade forces on the ground to protect the ground , reducing the wear blade .
    Since this is the use of mechanical push snow to shovel the snow pushed to the sides of the road, so we used to call snow or pushing snow machine .
    Advantages: a clear advantage when clearing snow and thick snow barrier. Even if compacted snow can be cleared.
    Disadvantages: one can not clear ice on the road . 2 For the potholed roads of snow during the depression can not be cleared .

Snow removal vehicles use and industry development prospects

The purpose of the snow sweeper is clear the snow and ice on the road. Snow sweeper are often used as the foundation of the dump truck chassis, plus special snow removal equipment modified assembly. Many government agencies will also use smaller vehicles to clear the pavement, road and the diameter of the snow. Temperate and polar regions responsible for road maintenance management agencies and contractors often have some snow sweeper, so we can put them during winter to ensure clear of ice and snow on the road and traffic safety. Airport snow sweeper is used to clear the snow and ice on the plane surface, runways and taxiways. Because in addition to endanger the aircraft take-off and landing, snow and ice on aircraft aerodynamic sex causing interference.
Snow removal machinery industry development
Using the multi-function snow sweeper snow removal is one of the highest efficiency in the snow removal methods. High latitudes the multi-functional snow sweeper technology of developed countries started early, after decades of development has been very mature, according to different road conditions and climate conditions can choose different types of equipment, efficient, reliable to use, is to achieve the advanced idea of "instant snow removal" ideal tool selection. Snow removal domestic machinery industry in the national big policy under the guidance of mechanized snow removal began to rapid development in recent years, started soon. But most of the products in both mechanical itself quality and snow removal effect in practical application are also has a certain gap with foreign advanced equipment.
