Abstract

The invention relates to a sweeping and brushing device for a road sweeping vehicle, which belongs to the technical field of street cleaning and comprises an inner support frame and an outer support frame arranged at the front end of the road sweeping vehicle, wherein a first rotating shaft and a swinging oil cylinder are arranged on the inner support frame, a second rotating shaft and a sweeping and brushing device are arranged on the outer support frame, an upper connecting rod, a lower connecting rod and a lifting oil cylinder are hinged between the first rotating shaft and the second rotating shaft, the upper connecting rod, the lower connecting rod, the first rotating shaft and the second rotating shaft form a first parallel four-rod mechanism in a vertical plane, and simultaneously, when the swinging oil cylinder moves, the inner support frame, the outer support frame, the first parallel four-rod mechanism and the elastic connecting rod form a second parallel four-rod mechanism in a horizontal projection surface. The sweeping and brushing device for the road sweeping vehicle has the advantage that garbage in the transverse recessed parts can be cleaned and swept.

Description

technical field [0001] The invention relates to a sweeping device of a road sweeper used for ground cleaning, belonging to the technical field of street cleaning. Background technique [0002] At present, when building roads or bridges, road expansion joints will be left on the road surface, and road expansion joints will be left on the bridge deck of the bridge. When roads and bridges are in use, expansion joints are more likely to accumulate debris than horizontal surfaces. As far as the applicant knows, all kinds of road sweepers on the existing market generally use 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 for cleaning. Rubbish. For example, the retrieved Chinese Patent Application No. 200810155829.3 discloses a sweeping device for a road sweeper. The sweeping device for a road sweeper uses a vertically placed disc-shaped brush. The lifting cylinder on t...
