Description

Technical Field

[0001] This utility model belongs to the field of snowplow technology, and specifically relates to a snowplow. Background Technology

[0002] Snowplows use high-speed rotating snow-cutting wheels to shovel snow from the ground and feed it into snow-throwing wheels for throwing, thus dispersing snow from the roadside. They are particularly common in snowy northern regions. However, existing snowplows have the following drawbacks: 1. Snowplows require simultaneous snow-cutting and snow-throwing operations, necessitating multiple transmission structures, resulting in complex transmission systems; 2. The presence of snow-cutting and snow-throwing equipment at the front of the snowplow obstructs forward visibility, creating large blind spots; 3. The snow-throwing direction is fixed, making it impossible to flexibly adjust the direction according to different road conditions. To address these issues, our company has designed and proposed a new snowplow. Utility Model Content
