Enhanced spraying device of cleaning and sweeping vehicle

Abstract

The invention relates to an enhanced spraying device of a cleaning and sweeping vehicle. The enhanced spraying device comprises a fan connecting pipe, a rear air pipe and a spraying pipe. According to the enhanced spraying device of the cleaning and sweeping vehicle, the air outlet of a fan of the cleaning and sweeping vehicle is guided to the position below the spraying pipe for assisting spraying, the air outlet airflow direction and the spraying direction can be controlled to be consistent all the time when the spraying incidence angle is adjusted, airflow loss is reduced, and the problems that the fixed spraying range of the cleaning and sweeping vehicle is limited and the spraying strength is poor are solved; the spraying effect of the cleaning and sweeping vehicle is effectively improved, and the application range of the cleaning and sweeping vehicle is widened.

Description

technical field [0001] The invention relates to an enhanced spraying device for a washing and sweeping vehicle, which belongs to the technical field of special vehicles. Background technique [0002] The sweeper is a multi-functional sanitation vehicle with multiple functions such as road sweeping, sweeping, cleaning, and spraying. The spray operation is to spray granular water droplets into the air through the nozzle to capture the fine dust in the air and purify the air. Spraying can be done alone or simultaneously with sweeping or cleaning operations. Existing cleaning and sweeping car spraying device is that the spray pipe is fixedly installed at the rear of the car, and sprays to the rear of the car during operation. As the incident angle of the nozzle increases, the spray distance in the horizontal direction also gradually increases, and the spray distance is the farthest when the incident angle is 45°; because the nozzle is fixed, the incident angle of the nozzle is...

AI Technical Summary

Problems solved by technology

Existing cleaning and sweeping car spraying device is that the spray pipe is fixedly installed at the rear of the car, and sprays to the rear of the car during operation. As the incident angle of the nozzle increases, the spray distance in the horizontal direction also gradually increases, and the spray distance is the farthest when the incident angle is 45°; because the nozzle is fixed, the incident angle of the nozzle is also certain, and the water pump pressure is constant. The spraying distance and height cannot be adjusted under certain conditions; second, the spraying force is limited, and the spraying force is completely dependent on the pressure provided by the high-pressure water pump, especially when cleaning and spraying work at the same time, the water pressure of the spray is small due to the diversion of high-pressure water , so the intensity of the spray is not enough, the spray effect is not ideal
