Auto-rotating sprayer

Abstract

Disclosed is an auto-rotating sprayer. The auto-rotating sprayer comprises a hollow rotating shaft, a rotator connected to the head of the rotating shaft, a case arranged on the circumference of the rotating shaft in a sleeving mode, and a connecting nut threadedly connected at the tap of the case; thrust spray nozzles are circumferentially distributed at the lower end of the rotator and obliquely and eccentrically arranged relative to the central axis of the rotator; the top of the rotator is obliquely provided with a cutting nozzle, and the thrust spray nozzles and the cutting nozzle are communicated with a water supply channel; the middle of the rotating shaft is provided with a damping ring unit, a damping slit is formed between the damping ring unit and the inner wall of the case; two bearings are matched between the rotating shaft and the case and on both sides of the damping ring unit; oil seals are arranged outside the bearings, and damping oil is filled between the two oil seals of the inner cavity of the case. According to the auto-rotating sprayer, the damping oil achieves lubricating effects as well as the aim of adjusting the rotating speed; a rotary sealing design breaks through the limitation of pressure insufficiency of the auto-rotating sprayer, and a 60 Mpa ultrahigh-pressure cleaning function can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of pipeline cleaning, and particularly refers to a self-rotating nozzle. Background technique [0002] The pipe cleaning nozzle is a high-pressure water jet cleaning product developed and manufactured for the cleaning of sewers and other industrial pipelines. It has been transformed from a single high-pressure water washing to a structure that can rotate under the reaction of water pressure; but the existing cleaning The spray head still has some shortcomings. For example, the utility model patent application number 201520774132.X discloses a high-pressure water rotating spray head. The lubricating oil in the shell only plays a role of lubricating the bearing and does not have the function of adjusting the speed. Summary of the invention [0003] The purpose of the present invention is to provide a self-rotating sprinkler. The damping oil not only has a lubricating effect, but also has the purpose of adjusting the...

[0002] The pipe cleaning nozzle is a high-pressure water jet cleaning product developed and manufactured for the cleaning of sewers and other industrial pipes. There are still some shortcomings in the nozzle. For example, the utility model patent with application number 201520774132.X discloses a high-pressure water rotary nozzle. The lubricating oil in the casing only serves to lubricate the bearing and does not have the function of adjusting the speed.
