Earth block prevent water spraying device of road sweeper suction nozzle

Abstract

This invention discloses a stoppage-proof sprinkler of road sweeping vehicle suction nozzle, which comprises annular spray pipe, water pipe joint and spray hole maintenance device, characterized in that it has more than two spray holes along the annular spray pipe inner wall, and the spray hole maintenance device is set in the annular spray pipe outer wall corresponding to each spray hole; the water pipe joint is set in the annular spray pipe; said invention can prevent the suction nozzle block up by the soil, increasing the operation speed and the labor intensity of the working people.

Description

technical field [0001] The invention belongs to the technical field of cleaning tools, and in particular relates to a road sweeping vehicle suction nozzle anti-clogging water spray device applied to a wet-sweeping road sweeping vehicle. Background technique [0002] At present, a large part of the urban road sweepers used in our country are wet-sweeping sweepers combined with suction and sweeping. This kind of road sweeper has the advantages of fast cleaning speed, low environmental pollution, and high cleaning efficiency. [0003] In order to avoid secondary pollution caused by flying dust, this kind of road sweeper is generally equipped with a water spray device on each sweeping plate and in the suction nozzle. The water spray device inside the suction nozzle is generally two fan-shaped nozzles. The spray of this nozzle is distributed in a fan shape, and the interaction area with the upstream airflow is large, and the penetrating ability of the water mist is poor. Brought...

AI Technical Summary

Problems solved by technology

The water spray device inside the suction nozzle is generally two fan-shaped nozzles. The spray of this nozzle is distributed in a fan shape, and the interaction area with the upstream airflow is large, and the penetrating ability of the water mist is poor. Brought downstream by the high-speed airflow, most of the water is concentrated near the wall of the suction pipe and cannot reach the center of the flow channel, causing the dust near the wall of the flow channel to quickly become sticky mud, and the mud blocks move under the action of the airflow The speed is very high. Once it hits the inner ring wall of the suction nozzle flow channel, it will be tightly adhered to the wall surface, and the mud will accumulate more and more, and finally the flow channel of the suction pipe will be completely blocked, causing the road sweeper to fail to work. Moreover, this kind of mud is difficult to clean out from the suction pipe because it is very sticky, which brings great inconvenience to the operators of the road sweeper.

[0004] At present, the cities in our country are in the construction period, and there is a lot of dust in many road sections, which has caused certain limitations to the use of road sweepers with fan-shaped nozzles installed in the suction nozzles.
