Description

Technical Field

[0001] This utility model relates to the field of green belt maintenance technology, and in particular to a road green belt maintenance device. Background Technology

[0002] The width of the green belt should be in proportion to the road width. Therefore, in order to prevent the plants in the green belt from growing wildly and obstructing the view, regular pruning and maintenance are required. Existing green belt maintenance devices have structures for recycling branches and leaves during specific pruning and maintenance. For example, the technology described in a road green belt maintenance device (Chinese patent, authorization announcement number CN219719177U) that "uses the suction force generated at the adsorption hood by the suction mechanism to suck the pruned branches and leaves of the green belt into the crushing hood" simply uses negative pressure to suck up branches and leaves. However, when pruning large-volume branches and leaves with trunks or when there are obstructions between branches and leaves with trunks, branches and leaves with trunks may fall off, resulting in problems with the incomplete and unstable recycling of branches and leaves with trunks.

[0003] Based on this, a road green belt maintenance device is proposed. Utility Model Content
