Road sweeper water mist spraying device capable of achieving dust falling function

Abstract

The invention discloses a road sweeper water mist spraying device capable of achieving a dust falling function. The water mist spraying device comprises a water mist spraying and dust falling device assembly and a pressurizing device assembly. The water mist spraying and dust falling device assembly comprises an inclined atomizing nozzle, a vertical water spraying nozzle, a nozzle fixing water pipe, a single-spraying connector, a double-spraying connector, a nozzle fixing water pipe end cover, a three-way port and the like; the pressurizing device assembly comprises a high-pressure water conveying pipe, a pressurizing gear pump, a water conveying pipe, a U-shaped hoop, a water storage tank and the like. The spraying device solves the problems that a spraying device of an existing road sweeper cannot simultaneously and effectively restrain dust raising at the rear portion and the front portion of a disc brush, or the sweeping efficiency is reduced due to water accumulation on the road surface, and has the advantages that dust raising pollution caused by the disc brush is effectively restrained, the sweeping efficiency is not reduced, and water is saved.

Description

technical field [0001] The invention belongs to the technical field of parts for special cleaning vehicles, and in particular relates to a water mist spraying device for a road cleaning vehicle capable of realizing the function of reducing dust, which can effectively reduce the dust caused by disc brushes during the cleaning process. Background technique [0002] With the rapid development of my country's road infrastructure, my country's road mileage will exceed 5 million kilometers in 2020. In order to reduce the work intensity of road cleaning personnel and improve cleaning efficiency, the demand for sweeping vehicles is increasing. Many sweepers are easy to cause dust pollution during the cleaning operation, but at present, the sweeper with the function of watering and dust reduction can only reduce the dust at the rear of the disc brush, but cannot effectively reduce the dust at the front of the disc brush. [0003] Invention patent CN108894155A discloses an atomization...

AI Technical Summary

Problems solved by technology

The atomization haze reduction device involved in the above invention patent uses a curved gooseneck to change the spray direction of water mist, but it needs to be manually controlled during use

Invention patent CN103790132A provides a fully enclosed rear sweeping energy-saving and environmentally friendly road sweeper, including a car chassis, a central side sweeping brush, a water circulation system, a hydraulic system, an upper garbage bin, and a rear garbage collection device. The engine configured above provides power for the whole vehicle; the engine can drive the high-pressure water pump in the water circulation system, the hydraulic pump in the hydraulic system and the rear garbage collection device in addition to driving the vehicle; A high-pressure nozzle is arranged on the front side of the disc brush to spray water and reduce dust. During the cleaning process, it is inevitable that the uncleaned garbage and dust on the road will be wet and some garbage cannot be cleaned and collected.

Invention patent CN108894169A discloses a rapid cleaning mechanism for a sweeping vehicle. The multi-directional water spraying dust suppression device uses two sets of ordinary high-pressure nozzles, one set is placed directly behind the plate brush to spray horizontally towards the plate brush, and the other set is placed at the rear of the vehicle vertically. Spraying straight down to the road surface, using this ordinary high-pressure nozzle and arrangement will not only reduce the cleaning efficiency due to the accumulation of water on the road, but also cannot effectively suppress the dust in front of the disc brush

[0004] The dust suppression device of the sweeping vehicle involved in the above invention patents cannot effectively suppress the dust generated at the front of the disc brush during the cleaning process, or it will cause water accumulation on the road and make the cleaning operation impossible

Based on the above problems, the present invention designs a water mist spraying device for a road sweeper that can realize the function of dust reduction. It can spray water to the rear of the disc brush and at the same time spray water mist to the front and upper part of the disc brush, which can effectively inhibit the dust removal of the road sweeper. The dust pollution caused by the disc brush during operation will not reduce the cleaning efficiency due to water accumulation in the road in front of the disc brush
