Description
Technical Field
The invention relates to a cleaning disc with an adjustable elastic broom, which is applied for divisional patent application with the application number of 2015100347952, the application date of 2015, 01, 24 and the name of 'cleaning disc with adjustable elastic broom', and the invention relates to a cleaning disc with a broom capable of being vertically installed.
Background
The sweeper is an environment-friendly device for sweeping road garbage, and can reduce the labor intensity of sanitation workers to a certain extent, so that the sweeper is advocated as a main device for sweeping urban roads at present. The cleaning disc used by the existing road sweeper mainly comprises a rotary disc and a plurality of bundles of bristles which are fixedly and uniformly distributed on the rotary disc. When the sweeper is in operation, the turntable is usually required to be inclined, so that the bristles on one side of the turntable touch the ground, and the bristles on the opposite side of the turntable are lifted off the ground. The bristles wear out relatively quickly and need to be replaced frequently. Usually, the whole cleaning disc needs to be replaced together when the cleaning disc is replaced, the rotating disc is usually not damaged, the rotating disc can still work normally, and the rotating disc is discarded together only because the length of the bristles is not enough, so that the cleaning disc is very waste.
In addition, the rotary disc and the bristles of the existing cleaning disc are fixedly connected, namely the bristles are directly embedded on the rotary disc, and when the cleaning disc meets some rugged road surfaces, the bristles cannot elastically respond, and only the hard brush can pass, so that the abrasion of the bristles is accelerated.
