Road sweeper and sweeping device thereof

Abstract

The invention relates to a road sweeper and a sweeping device thereof. The sweeping device comprises a connection frame, a sweeping body and a floating regulation device. The sweeping body is mounted on the connection frame, a first end of the connection frame is connected with a chassis frame of the road sweeper, and the connection frame is capable of rotating relative to a connection point of the first end of the connection frame and the chassis frame. A position close to a second end of the connection frame is connected with the chassis frame through the floating regulation device to make the connection frame float up and down along with up-down changes of a swept road surface under the action of the floating regulation device so as to drive the sweeping body to float up and down. By the floating regulation device, the connection frame connected with the sweeping body is capable of floating up and down along with up-down changes of the swept road surface so as to drive the sweeping body to float up and down, damages caused by hard collision of the sweeping body and the swept road surface in up-down changes can be avoided, the service life of the sweeping device is prolonged, and sweeping efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a cleaning device of a road sweeper and the road sweeper. Background technique [0002] A road sweeper is a mechanical device with a special chassis and a power drive for removing and collecting ground (road) rubbish. Road sweepers are not only suitable for the cleaning and maintenance of urban arterial roads, but also for cleaning work in squares, parks, schools or communities. The front end of the chassis frame of the road sweeper is equipped with a cleaning device. During the cleaning operation, the cleaning device lowers the disc brush to contact with the road surface, sprays water and cleans the road surface. [0003] In the prior art, there is a lifting mechanism of a small-sized electric cleaning vehicle disc brush, such as figure 1 As shown, the mechanism includes a bracket a5, an electric push rod a4 and a planar six-bar mechanism a8. The planar six-bar m...

Problems solved by technology

[0010] 3. The grounding pressure of the disc brush cannot be adjusted in time and continuously. There are two consequences: one is that the grounding pressure of the disc brush cannot be increased in time when cleaning the road surface is bad, resulting in poor cleaning effect; When the grounding pressure of the disc brush is large, the grounding pressure of the disc brush cannot be appropriately reduced, resulting in faster wear of the bristles, shortening the service life of the disc brush, and also causing a waste of energy for the road sweeper
