a road sweeper

Abstract

The invention relates to a road sweeping vehicle, which comprises a vehicle body and a mounting frame installed on the bottom surface of the vehicle body. A garbage adsorption device and a garbage cleaning device are fixedly installed on the mounting frame. The garbage cleaning device includes a cleaning brush and a lifting cylinder. An adjustment rod is hinged on the frame, the lower end of the adjustment rod is rotated and a rotating wheel is installed, a return spring is connected to the adjustment rod, the other end of the return spring is connected with the mounting frame, and the return spring is located on the side of the adjustment rod close to the front of the car body; A proximity switch is fixedly installed on the installation frame, and a response block for triggering the proximity switch is installed on the adjusting rod. An indicator light is arranged in the cab of the car body. adjacent, and make the indicator light glow. It can remind the people in the vehicle to stop in time when the vehicle passes the expansion joint, and then clean the expansion joint; it is more convenient, simple and more efficient than the previous cleaning method.

Description

technical field [0001] The invention relates to the technical field of road cleaning, in particular to a road cleaning vehicle. Background technique [0002] At present, when roads or bridges are being built, road expansion joints are left on the pavement of the road, and road expansion joints are also left on the bridge deck of the bridge. When roads and bridges are in use, expansion joints are more likely to accumulate debris than level road surfaces. Most of the various road sweepers currently on the market adopt vertically placed disc-shaped sweeping brushes or long roller brushes arranged at the rear end of the road sweeper, which cannot go deep into the depressions to clean the garbage. Because the road sweeper needs to drive on the road, the height of the roller brush is usually set at a position slightly close to the ground, and the bottom surface of the road expansion joint is lower than the road surface, so the roller brush does not work well when it is rotating. ...

AI Technical Summary

Problems solved by technology

At present, most of the various road sweepers on the market use vertically placed disc-shaped sweeping brushes or long roller brushes installed at the rear end of the road sweeper, which cannot go deep into the depressions to clean garbage

Because the road sweeper needs to drive on the road, the height of the roller brush is usually set at a position slightly close to the ground, and the bottom height of the road expansion joint is lower than the road surface, so the roller brush does not work well when it is rotating. Clean out the garbage in the road expansion joints

Although the existing roller brush is usually connected to the bottom of the car body through a lifting rod, it can also be lifted up and down, but this structure is only used to adjust the size of the gap between the roller brush and the ground, and people cannot accurately move the vehicle. When reaching the expansion joint, adjust the roller brush so that the roller brush is embedded in the expansion joint and clean up the garbage in the expansion joint

As a result, it is difficult to clean the road expansion joints on the bridge, and the manual cleaning efficiency is low
