Elastic broom with adjustable elastic force

Abstract

The invention discloses an elastic besom with adjustable elasticity. The elastic besom comprises a cylinder body, a piston rod, a piston, a brush, a pressure spring, a pressing plate and an adjustment bolt, wherein the cylinder body is arranged upside down, namely an opening of the cylinder body is downward; a threaded hole is formed in the rear wall of the cylinder body; the adjustment bolt is arranged in the threaded hole in a penetrating manner; the lower end of the adjustment bolt is propped against the pressing plate; the pressing plate is positioned in the inner cavity of the cylinder body; the piston is arranged on the piston rod; the pressure spring is arranged between the piston and the pressing plate; the lower end part of the piston rod is detachably connected with the brush; the brush of the elastic besom can elastically stretch according to the ups and downs change of a pavement, so that the abrasion to the bristles is alleviated, and the service life of the brush is prolonged; furthermore, the brush can be independently replaced, and the whole cleaning disk does not need to be replaced, so that the cost can be reduced. More importantly, the elasticity of elastic stretching of the elastic besom can be adjusted according to the abrasion degree of each brush, so that the abrasion to the brush can tend to be consistent; meanwhile, the cleaning requirements of different pavements can be met.

Description

technical field [0001] The invention relates to an elastic broom with adjustable elastic force. Background technique [0002] Sweeper is a kind of environmental protection equipment for cleaning road garbage. It can reduce the labor intensity of sanitation workers to a certain extent, so it is praised as the main equipment for cleaning urban roads. The used cleaning disc of existing road sweeping vehicles mainly includes a rotating disc and some bundles of bristles fixed and evenly distributed on the rotating disc. When the sweeper is working, it is usually necessary to tilt the turntable so that the bristles on one side touch the ground, while the bristles on the other side are lifted off the ground. The bristles wear out quickly and need to be replaced frequently. Usually when replacing, the whole cleaning disc needs to be replaced together, and the rotating disc is often not damaged, and it can still work normally, but it is discarded together because the length of the ...

The bristles wear out quickly and need to be replaced frequently

Usually, the entire cleaning disc needs to be replaced together, and the turntable is often not damaged, and it can still work normally, but it is discarded together because the length of the bristles is not enough, which is very wasteful.

[0003] In addition, the turntable and the bristles of the existing cleaning disc are fixedly connected, that is, the bristles are directly embedded on the turntable. When encountering some rough roads, the bristles cannot respond elastically, so they can only brush over abruptly, which accelerates the bristles. wear and tear
