Variable flow area suction nozzle applied to road sweeper
The invention discloses a variable flow area suction nozzle applied to a road sweeper. The variable flow area suction nozzle comprises a suction nozzle body and a conveying pipe arranged on the suction nozzle body, as well as a front air baffle plate arranged at the front end of the suction nozzle body and a rear air baffle plate at the back end of the suction nozzle body, wherein air inlet passages are formed between the bottom ends of the front air baffle plate and the rear air baffle plate and road surface when the sweeper works; a suction inner cavity communicated with the conveying pipe is formed among the suction body, the front air baffle plate and the rear air baffle plate; a tongue plate arranged on the suction nozzle body is arranged in the suction nozzle inner cavity; and the tongue plate can swing when the sweeper works so that the cross-sectional flow area of the suction inner cavity is increased or reduced. By optimizing the flow field, the suction nozzle disclosed by the invention can guarantee relatively good adaptability of the road sweeper to dense garbage and light garbage on the ground, so that the adaptability of the road sweeper to the road garbage is enhanced, and the sweeping quality and working efficiency of the road sweeper are improved.
