Abstract:
A side brush structure for road sweeper, including: a main shaft (110) configured to connect the side brush structure (100) to the road sweeper; a side brush assembly (120), wherein the main shaft (110) is connected to the side brush assembly (120) by a first anti-collision assembly (130) and a second anti-collision assembly (140) in turn. The second anti-collision assembly (140) is arranged to be rotatable in relation to the first anti-collision assembly (130), and the side brush assembly (120) is inclinable by moving in multiple directions and within a certain range in relation to the first anti-collision assembly (130). The first anti-collision assembly (130) and the second anti-collision assembly (140) comprise a first rebounding mechanism (131) and a second rebounding mechanism (141), respectively. The side brush structure (100) not only enables rotation of the side brush assembly (120) in multiple directions, but resets the side brush assembly (120) to its initial position in time.
