Road sweeper and sweeping device thereof, anti-collision sweeping disc arm mechanism and control method

Abstract

The invention discloses a road sweeper and a sweeping device thereof, an anti-collision sweeping disc arm mechanism and a control method.The anti-collision sweeping disc arm mechanism comprises a sweeping disc arm, a mounting base and an impact self-adaptive adjusting mechanism, one end of the sweeping disc arm is used for mounting a sweeping disc, and the other end of the sweeping disc arm is mounted on the mounting base in a swinging mode; the impact self-adaptive adjusting mechanism comprises at least two elastic telescopic devices, one of the sweeping plate arm and the mounting seat is rotatably connected with one end of the elastic telescopic device, and the other one of the sweeping plate arm and the mounting seat is slidably and rotatably connected with the other end of the elastic telescopic device; the elastic telescopic devices are arranged on the two sides of the middle line, swinging relative to the mounting base, of the sweeping disc arm respectively. The anti-collision sweeping disc arm mechanism can prevent the sweeping disc arm and the sweeping disc on the sweeping disc arm from being damaged due to the collision of external obstacles, is beneficial for ensuring the sweeping operation of the sweeping disc in a complex environment, and improves the reliability of the sweeping device of the sweeping vehicle.

Description

technical field [0001] The invention relates to the technical field of sanitation equipment, in particular to a road sweeper and its cleaning device, an anti-collision sweeping arm mechanism and a control method. Background technique [0002] The road sweeper collects garbage by combining suction and sweeping, and has the function of dust removal. It can quickly and efficiently clean the road and ensure the cleanliness of the urban environment. It has become a necessity in modern cities. [0003] In the prior art, the cleaning device of the road sweeper is mostly composed of a sweeping plate and a mechanical arm. The sweeping plate is connected to the vehicle body through the mechanical arm. During the operation, due to the complicated road conditions near the curb, the cleaning device will inevitably encounter bosses. Therefore, how to provide an anti-impact sweeping structure to avoid damage to the cleaning device when it is subjected to external impact has become an impor...
