Technical Field
The invention belongs to the technical field of road sweeping, and particularly relates to a hardness-adjustable flexible pavement dirt removing device.
Background
The road sweeper is a mechanical device with a special chassis and a power driving device and used for removing and collecting ground (road) garbage. The road sweeper not only can be suitable for cleaning and maintaining urban trunk roads, but also can be suitable for cleaning work in places such as squares, parks, schools or communities. In general, a sweeping device is provided at the front end of a road sweeper to collect and dispose of garbage. When the road sweeper is in a sweeping operation state, the sweeping device is in contact with the ground to complete sweeping work.
In the prior art, a plurality of different types of road sweepers exist, but in most of the sweeping devices on the road sweepers, the lifting oil cylinders are rigidly connected with the brush arms, so that the grounding degree of the sweeper brush cannot be adjusted, and the inclination angle of the sweeper brush cannot be adjusted, which causes inconvenience for collecting garbage and low sweeping efficiency; in many cases, the road sweeper needs to sweep a narrow area of a field, but because the whole size of the road sweeper is large, a sweeping device is difficult to stretch into the narrow area, so that the sweeping device cannot sweep the narrow area, and a sweeping dead angle exists; in addition, the maximum cleaning width of the sweeper is limited, and cannot be adjusted at any time according to needs.

However, the cleaning of the sticky dirt for this cold air release type has disadvantages in that:
1. the cleaning process needs to release cold air continuously, the cold air is poor in cooling effect after being released and combined with the surrounding environment rapidly, and when the cleaning machine is used outdoors, only a small amount of cold air can reach the periphery of sticky dirt under the blowing of natural wind, so that the cooling effect is achieved.
2. No clear solution is proposed as to how sticky soils such as chewing gum scraped off the floor are treated.
3. The plane scraper, the iron brush or the shovel are made of hard metal, scratch the ground, influence the attractiveness of the ground after being used for a long time indoors or on landscape roads, and strip gravel particles on glass asphalt pavements outdoors under the condition that asphalt roads are gradually popularized, so that pits are formed on the ground, even sharp bulges are formed, and the safety of tires is threatened.
