Description

Technical Field

[0001] This utility model relates to the field of roller brush technology for sweepers, specifically to an easy-to-maintain roller brush structure for sweepers. Background Technology

[0002] Sweepers typically use multiple roller brushes to transfer swept garbage from the ground to the discharge port of the casing, directly transferring the garbage into the garbage bin. However, existing roller brushes are all installed inside the casing, which is a split design consisting of front and rear parts. Placing the roller brushes between these two parts requires disassembling the casing and internal components for maintenance, resulting in low maintenance efficiency. Therefore, this sweeper was designed with an easy-to-maintain roller brush structure. The easily disassembled roller brush improves the equipment's maintenance efficiency, while the fact that all parts can be disassembled reduces maintenance costs. Utility Model Content
