Description

Technical Field

[0001] This utility model relates to the field of snow removal equipment technology, and in particular to a snow removal vehicle with a precision spreading device. Background Technology

[0002] Existing snowplows are usually equipped with de-icing agent spreading devices. The purpose of installing de-icing agent spreading devices on snowplows is to achieve the coordinated operation of "mechanical snow removal + chemical snow melting", improve snow removal efficiency, ensure road traffic safety, and reduce secondary hazards caused by residual ice and snow.

[0003] The spreading device primarily uses a high-speed rotating spreading disc to radially project the de-icing agent falling into the center of the disc, achieving uniform and wide-area road surface coverage. However, existing spreading discs are fixed in place, and vehicles cannot adjust the disc angle according to their lane. When the vehicle's lane approaches a green belt, the de-icing agent is scattered into the green belt. Chloride-based de-icing agents can cause soil salinization, impair the water absorption capacity of plant roots, and lead to root rot or even plant death.

[0004] To address the problems in existing technologies, we propose a snowplow with a precision spreading device. Utility Model Content
