Abstract

The purpose of the present invention is to provide a sprinkling nozzle rotating apparatus for a road floor sprinkler truck, rotating a direction of water injection of a sprinkling unit, to have a wide injection range to significantly improve a performance of sprinkling. The present invention comprises: a sprinkling unit installed in a front side of a sprinkler truck to inject water supplied from a water tank provided to the sprinkler truck; and an operation unit installed to rotate the sprinkling unit to control the direction of water injection.

Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a sprinkling-

More particularly, the present invention relates to a sprinkler revolving operation device for a road bottom sprinkler, and more particularly, to a sprinkler revolving operation device for a road bottom sprinkler, The present invention relates to a sprinkler rotation actuator for a bottom sprinkler.

Generally, each local government or an organization that manages roads periodically removes foreign matter and fine dust accumulated on the roads to maintain and maintain the roads in a clean condition.

A lot of manpower is required for the maintenance of the road surface. Since the work is performed in such a manner that the worker uses the broom directly to sweep off the foreign material on the road surface or sweeps away the foreign material on the road surface such as a road sweeper, Treatment of fine dust among air pollutants was not smooth.

Accordingly, a water sprayer for automatically cleaning the road surface is provided for easy removal of foreign matter and fine dust on the road surface. Most of the water sprayers proposed are equipped with a water tank, and a plurality of water sprayers Nozzles are provided.

As a result, the water sprayer separates foreign matter by injecting water at high pressure toward the road surface while traveling on the road, and the separated foreign matter is introduced into the drain port together with the water to be treated.

The water spray pump is used to clean the road surface by supplying water to the water spray device provided in the vehicle.

A conventional water sprayer will be schematically described. A water spray nozzle is provided with a water tank, a nozzle, and a supply pipe for supplying water to the nozzle.

This sprayer is sprayed with water supplied from a water tank through a nozzle to clean the road surface. That is, the water stored in the water tank can be sprayed through the nozzle when the watercourse is running, thereby eliminating the dust generated in the road or the construction site.

However, since the nozzle is installed to be fixed to the lower end of the front bumper of the vehicle in the prior art, the water is sprayed perpendicularly to the road so that the foreign matter accumulated on the road is scattered and the troublesome post- This was caused

Further, since the direction of the nozzle can not be adjusted, the nozzle is sprayed only in one direction, so that the cleaning is not simple and clean.

In order to compensate for this, there is a problem that a worker takes a long time to work because he or she must perform additional work using a water spraying hose.
