Description

Technical Field

[0001] This utility model relates to the technical field of road greening pruning equipment, and in particular to a new type of comprehensive greening maintenance vehicle. Background Technology

[0002] The post-construction watering, pruning, weeding, pesticide application, and replanting of greenery are collectively referred to as maintenance. This work is simple but essential. Pruning the greenery along roadsides is one of the main tasks of highway maintenance. Highway greenery maintenance not only affects the aesthetics of the environment and air purification, but also impacts driver visibility, absorbing vehicle exhaust fumes and dust, and is crucial for preventing glare during nighttime driving. Currently, pruning of green belts along highways is mainly done manually using handheld greening pruning machines or other semi-hydraulic hedge trimming equipment, which is inefficient and lacks adaptability.
