Road sweeper

Abstract

The invention provides a road sweeper which breaks through the structure form of a traditional road sweeper. Under the action of exhaust force of an exhaust fan, dust swept up from the ground can enter a dustbin along with air through a conveying device, the dust and air in the dustbin enter dust removal filter drums together through an exhaust opening of the dustbin; the air mixed with the dust is filtered by the dust removal filter drums, so that the dust is filtered out of the dust removal filter drums, and then the dust gathered outside the dust removal filter drums is stirred to fall in the dustbin through a stirring device; and all the dust is taken as garbage to be adsorbed, and clean air passes through the dust removal filter drums and then is exhausted to the outside through an outlet of the exhaust fan. When the road sweeper encounters with obstacles which cannot be swept away, main brushes swing upwards with the pivot position of a swing arm and the conveying device as a rotating point through the swing arm, so that the main brushes float vertically in a self-adaption manner according to road conditions, and the main brushes are prevented from being damaged. After the road sweeper encounters with large garbage, a first elastic baffle can be upwards lifted by a lifting mechanism so that the large garbage can smoothly enter main brush shells and then be swept away by the main brushes.

Description

technical field [0001] The invention relates to the field of road sweepers, in particular to a road sweeper. Background technique [0002] The structure of the road sweeper is known, such as Chinese utility model patent CN201320538627.3 discloses a kind of road sweeper, comprising the road sweeper body and the vehicle-mounted garbage bin installed on the road sweeper body; it is characterized in that, in the vehicle-mounted garbage A garbage collection device is installed on the box, and the garbage collection device includes a garbage collection part and a conveying part drawn out from the vehicle-mounted garbage box, which is connected as a whole. The angle of contact or disengagement of the collection part relative to the road surface is adjusted by the oil cylinder. The garbage collection part and the conveying part include a semi-closed cabinet, and the open parts of the cabinet are respectively equipped with arranged main roller brushes, auxiliary roller brushes, acti...

AI Technical Summary

Problems solved by technology

[0003] This utility model is similar to the structure of most road sweepers on the market. During actual use, there will be dust flying, which will seriously pollute the air and bring many troubles to people; the main roller brushes need to float up and down according to the road conditions. When encountering an obstacle that cannot be cleaned, it is necessary to float the main roller brush to avoid the obstacle and avoid damage to the main roller brush. If it is damaged, the action of cleaning and collecting garbage is not smooth enough; when encountering large pieces of garbage, the large pieces of garbage can easily block the garbage inlet of the main brush housing, which will seriously affect the cleaning effect or even make it impossible to clean; cleaning and collection The actions of the garbage are not coordinated enough; the effect and efficiency of cleaning need to be improved
