Description

Technical Field

[0001] The utility model relates to the technical field of cleaning vehicles, in particular to a duckbill structure used for a road cleaning vehicle. Background Art

[0002] Existing road cleaning vehicles are generally equipped with a water tank and a water pipe connected to the water tank. A nozzle for spraying water is provided at the end of the water pipe. The nozzle sprays water to achieve the operating functions of cleaning curbs, sweeping / driving away garbage, and washing the road surface.

DETAILED DESCRIPTION

[0015] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0016] Example: Figure 1 and Figure 2As shown, the utility model is a duckbill structure for a road cleaning vehicle. The water outlet pipe used for connecting the cleaning vehicle comprises an access pipe 1, which is a four-way pipe, wherein the water inlet thereof is connected to the water outlet pipe of the cleaning vehicle, and the other three water outlets are respectively connected to the first branch pipe 11, the second branch pipe 21 and the third branch pipe 31, wherein the first branch pipe 11, the second branch pipe 21 and the third branch pipe 31 are arranged in a trident shape, and the first branch pipe 11, the second branch pipe 21 and the third branch pipe 31 are respectively provided with a first valve 12, a second valve 22 and a third valve 32, a valve end of the first valve 12 is provided with a first duckbill nozzle 13, a valve end of the third valve 32 is provided with a third duckbill nozzle 33, a valve end of the second valve 22 is connected with a bend pipe 24, and a second duckbill nozzle 23 is provided at the end of the bend pipe 24, and a first valve switch 121, a second valve switch 221 and a third valve switch 321 are respectively provided on the outer sides of the first valve 12, the second valve 22 and the third valve 32, and the three valve switches are used to control the opening and closing of the corresponding valves.

[0017] As a preferred embodiment, a bend pipe 24 is provided between the second duckbill nozzle 23 and the second valve 22, and the bend pipe 24 is connected to the second valve 22 by a thread, and the direction of the bend pipe 24 can be adjusted by rotating the thread. Preferably, the direction of the second duckbill nozzle 23 is adjusted to be the same as the nozzle direction of the first duckbill nozzle 13, and opposite to the nozzle direction of the third duckbill nozzle 33. In this way, the second duckbill nozzle can be used to clean / drive away garbage, the first duckbill nozzle can be used to clean the curb, and the third duckbill nozzle can be used to clean the road surface.
