Abstract

The invention relates to a suction nozzle device of a sweeping car, comprising a frame body and an air suction port arranged on the frame body, wherein a cavity which is communicated with the air suction port is formed in the frame body; the frame body comprises an elastic baffle plate positioned at one side of the cavity; one end of the elastic baffle plate is fixed on the frame body; the suction nozzle device of the sweeping car also comprises an overturning mechanism which is in driving connection with the elastic baffle plate; when the overturning mechanism overturns, the overturning mechanism drives the elastic baffle plate to overturn upwards; and when the overturning mechanism resets, the elastic baffle plate returns to the original state under self elasticity. Compared with the prior art, the suction nozzle device disclosed by the invention has the advantages that: because the overturning mechanism is additionally arranged, when meeting wastes, such as big leaves and the like with larger size, the elastic baffle plate is overturned, the size of the opening of the suction nozzle is increased, the space of a suction pipe, in which the wastes enter, is increased, and the negative pressure of the suction nozzle cannot be reduced at the instant of overturning the elastic baffle plate, therefore the suction effect cannot be influenced.

Description

technical field

[0001] The present invention relates to a road surface cleaning equipment, and in particular to a suction-sweeping road sweeper and its suction nozzle device. Background technique

[0002] At present, due to the high cleaning efficiency and safety of road sweepers, road sweepers have been increasingly used for cleaning and cleaning in environments that are not suitable for manual cleaning, such as highways and urban roads.

[0003] Road sweepers can be divided into suction sweeping, pure suction, and pure sweeping according to their working methods. The suction-sweeping road sweeper has good suction, dust removal and conveying effects on fine garbage and dust, which effectively reduces the environmental pollution caused by cleaning. Ideal cleaning equipment for road cleaning.

[0004] The suction nozzle is an important part of the suction sweeper. It relies on the negative pressure of the fan to suck the garbage on the road to the garbage bin. Please refer...
