Electric watering spray gun

Abstract

The invention discloses an electric watering spray gun, which comprises a water inlet pipe, a water outlet pipe, a first drive device, a second drive device, a first elbow pipe, a second elbow pipe, a first three-way joint and a second three-way joint. The first three-way joint is provided with a first water inlet, a first water outlet and a second water outlet; the second three-way joint is provided with a second water inlet, a third water inlet and a third water outlet; the water outlet end of the water inlet pipe is in sealed connection with the first water inlet; the first water outlet is in sealed connection with the second water inlet through the first elbow pipe; the second water outlet is in sealed connection with the third water inlet through the second elbow pipe; the third water outlet is in sealed connection with the water inlet end of the water outlet pipe; the first drive device is in transmission connection with the water inlet pipe; the second drive device is in transmission connection with the second three-way joint. The electric watering spray gun provided by the invention is simple and reasonable in structure, convenient to operate in a labor-saving way, powerful in water flow, larger in output flow, larger in spray gun rotation range, and better in spraying effect.

Description

technical field [0001] The invention relates to the technical field of sprinklers, in particular to an electric sprinkler gun. Background technique [0002] The sprinkler gun, also known as the sprinkler, is mainly used in large-scale coal mines, iron mines, steel mills, power plants, coal terminals, and ore departments' stockyards, coal stockyards, ore yards, etc., for sprinkling and dust prevention and road washing, Sprinkler irrigation for large forest farms and orchards. Traditional sprinkler guns are all controlled by manpower, resulting in high work intensity for operators. For this reason, electric sprinkler guns also appear at present, and the sprinkler guns are automatically controlled by setting corresponding driving mechanisms, which can effectively reduce the labor intensity. [0003] Chinese patent (Application No. 201310043395.9) discloses a sprinkler gun automatic adjustment rotation device, its structure includes straight through, S elbow, 90-degree elbow, ...

AI Technical Summary

Problems solved by technology

[0005] However, the defects of the above-mentioned sprinkler gun automatic adjustment rotation device are: first, due to the single-way water supply structure formed by the cooperation of the S elbow and the 90-degree elbow, the water path is too circuitous, and the water force drops significantly during the flow process. The output flow rate is small; secondly, due to the unreasonable installation structure of the transmission device, the rotation range of the spray gun is small, and the spraying effect is not good
