Trimming means for highway afforestationTechnical Field
The invention relates to the technical field of trimming equipment, in particular to a trimming device for road greening.
Background
Green belts are arranged on two sides of the highway, so that on one hand, urban environment can be beautified, and on the other hand, environmental pollution can be reduced, automobile exhaust can be absorbed, and the like. The shrub vegetation in the green belt needs to be trimmed regularly, and the green belt trimming work in the prior art is usually performed by manually holding a trimmer, so that the trimming is troublesome, time and labor are wasted, and the trimming uniformity cannot be guaranteed. In addition, there are some pruning robots or pruning devices for greenbelts, which are complex in structure, occupy large space and cannot be stored, and generally only can prune the top or side of the shrubs at the same time, and when the pruning state is switched between the top pruning state and the side pruning state, a certain time is required to be spent, so that the overall pruning efficiency is relatively low whether the pruning robot or the pruning device is manually held or utilized.
