Description

Technical Field

[0001] The utility model belongs to the technical field of road snow removal equipment, and in particular relates to a downward pressing device for a snowplow of a high-speed snowplow. Background Art

[0002] In most parts of my country, snow must be cleared promptly after every winter snowfall to ensure smooth traffic. However, during severe weather such as blizzards, snow removal becomes increasingly difficult, and manual snow and ice removal is no longer suitable for current needs. Failure to promptly clear snow will cause significant inconvenience to people's travel and daily lives, and will have a significant impact on economic and social development.

[0003] Among the snow-plowing steel plates currently used on roads in cities both domestically and internationally, plowing is the most common application. However, most snowplows have obstacle-crossing capabilities, but they are generally monolithic and have rigid linkages that are unable to cope with the constantly changing impact forces during operation. This results in uneven force distribution and excessive localized stress, leading to deformation and reduced service life. Summary of the Invention
