Technical Field

[0001] The invention relates to the technical field of garbage cleaning vehicles, in particular to a city road garbage cleaning vehicle. Background Art

[0002] Urban road garbage cleaning trucks are used in city centers to clean up solid waste accumulated on street pavements, such as piles of garbage. They are tools used for collection and loading. During the free movement of the cleaning truck, the brushes installed on the vehicle body are driven to work, thereby achieving the effect of cleaning and removing solid waste from the street pavement.

[0003] When in use, existing urban road garbage cleaning vehicles generally use the kinetic energy of the vehicle body during driving and the brush structure installed on the front side of the vehicle body to clean and remove solid waste accumulated on the street surface. However, in order to reduce the splashing and dust of solid waste caused by the centrifugal effect of the high-speed rotation of the brush during cleaning, the maximum rotation speed of the brush component is limited, which also leads to a low cleaning degree when the cleaning vehicle cleans the adhesive solid waste on the street surface. Due to the stickiness or the degree of solidification of the waste on the road surface, it is very easy to produce residues of the cleaned waste, which takes a lot of time in the continuous cleaning process and the cleaning effect is not good.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original urban road garbage cleaning vehicle. Summary of the invention

[0020] Furthermore, when there is a lot of solid waste accumulation, the cleaning brush is placed in the middle of the sweeping brush. Under the synchronous action of the sweeping brush and the cleaning brush, the cleaning brush and the sweeping brush are superimposed to form a moderate hardness and softness state, which can drive the excessive accumulation of solid waste. The sweeping brush will not be insufficient in hardness due to too much waste, causing large-area extrusion deformation of the sweeping brush to affect the cleaning effect of road garbage.

[0021] Furthermore, when stubborn and easily residual solid waste accumulates, the cleaning brush is completely placed under the sweeping brush, and the cleaning brush is tightened and rigidified by utilizing the squeezing and hydraulic state, so that the stubborn residue on the street surface can be cleaned when rotating. At the same time, the cleaning brush is hidden and soft in the normal state, and it will not cause collision with the street surface when the sweeping brush is in action, resulting in scratches and knocking damage to the cross-section of the road surface.
