Abstract

The invention relates to the technical field of environmental sanitary machines, in particular to an air duct part and a street cleaner. The air duct part comprises an air duct part body; the air ductpart body comprises an air duct, an air duct inlet and an air duct outlet; the air duct is arranged within the air duct part body; the air duct inlet and the air duct outlet are in communication withthe air duct; air flow flows into the air duct from the air duct inlet and flows out from the air duct outlet; and moreover, the air duct part further comprises a silencing and noise reducing structure; and the silencing and noise reducing structure is used for reducing the noise of the air flow flowing through the air duct. According to the air duct part, as the silencing and noise reducing structure is arranged on the air duct part, the noise of the air flow flowing through the air duct can be reduced; therefore, the strength of the noise of the air duct part can be effectively weakened. And moreover, the air duct part also has the advantages that the pressure distribution within the air duct part can be improved, the operation efficiency can be enhanced, energy consumption can be reduced and the reliability and durability of the air duct part and appurtenances thereof can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of sanitation machinery, in particular to an air duct piece and a road cleaning vehicle. Background technique [0002] The air duct is an important part of the pneumatic conveying system of sanitation machinery such as road cleaning vehicles. When the road cleaning vehicle is working, the airflow generated by the power source (fan) of the pneumatic conveying system flows through the air duct and flows to the air conveying system. Hair outlet. When the air flow passes through the air duct, pressure loss will be generated and a large noise will be generated. [0003] Taking the road cleaning vehicle as an example, the air duct is generally a square pipe with a large diameter. When the air passes through the bend of the air duct, the energy loss due to the change of the flow direction and the uneven distribution of the fluid will cause the flow resistance of the pipe to increase. , the fluid is easy to form t...
