Watering spray gun with automatically rotating shower nozzle

Abstract

The invention discloses a watering spray gun with an automatically rotating shower nozzle. The watering spray gun with the automatically rotating shower nozzle comprises an upper spray gun body, a lower spray gun body, a throttling device, a speed regulating device, a steering device and the shower nozzle; the lower spray gun body is connected through the throttling device; one end of the speed regulating device is connected to the lower spray gun body through one end of a pipeline and the other end of the speed regulating device is connected to a P opening of the reversing valve through a water inlet pipe; the reversing device which is installed on the upper spray gun body comprises a water inlet pipe, a reversing valve, a valve block, a hydraulic cylinder, a reversing blocking block, a rack and a pinion; a first reversing blocking block and a second reversing blocking block are installed on the valve block; the end portion of a shifting rod of the reversing valve is arranged between the first reversing blocking block and the second reversing blocking block; the nozzle is installed on the upper spray gun body through a bearing. According to the watering spray gun with the automatically rotating shower nozzle, an electric element is avoided, the safety is high, and application occasions are wide; the valve block which is adopted plays a role as a pipeline for flowing between the reversing valve and the hydraulic cylinder, the hydraulic pipeline is simplified, and the device structure is compact.

Description

technical field [0001] The invention relates to the technical field of dust reduction by spraying, in particular to a watering spray gun with a automatically rotating spray head. Background technique [0002] Sprinkler spray guns are suitable for sprinkling dust and cooling of materials and solid stacks in the yard, suitable for low temperature, corrosion, and dust environments, and are widely used in power plants with severe dust, port coal terminals, railway freight yards, mines, coal mines, steel plants, Coal yards, coal piles, stockyards, raw material yards, and ore yards of industrial enterprises such as coal coke and chemical industry. [0003] Traditional sprinkler lances rely on the momentum of the water flow to power the lance rotation, which often results in a large amount of water pooling around the lance station. In cold weather conditions, the frozen water will bring hidden dangers to production safety. At present, the new sprinkler guns in use mainly include ...

Problems solved by technology

[0003] Traditional sprinkler guns rely on the momentum of water flow to provide power for the rotation of the spray gun, which often results in a large amount of water around the spray gun station

In cold weather conditions, these accumulated water will bring hidden dangers to production safety after freezing

At present, the new sprinkler guns in use mainly include grooved cam type spray guns and ratchet type spray guns. These new sprinkler guns overcome the problem of water accumulation around the spray gun station, but they have disadvantages such as easy wear and low reliability.

After being used for a period of time, the grooved cam spray gun often has difficulty in reversing due to severe wear; while the movement of the ratchet spray gun is intermittent, which has the disadvantages of poor spraying effect and high failure rate.

Sprinkler guns generally work in the open air. Due to the harsh working environment, poor reliability and low service life are common problems.
