Air duct of sprayer

Abstract

The invention relates to an air duct of a sprayer. The air duct of the sprayer comprises a front barrel, a middle barrel and a back barrel successively connected from left to right. The middle barrelis composed of a middle outer barrel and a middle inner barrel; a motor is arranged in the middle inner barrel; an outer retaining structure is arranged on the inner surface of one end of the middle outer barrel; an inner retaining structure in retaining fit to the outer retaining structure is arranged on the outer surface of one end of the middle inner barrel; a connecting structure detachably and fixedly connected to the middle inner barrel is arranged on the inner side surface of the other end of the middle outer barrel; and an annular fit clearance capable of moving radially relatively isformed between the inner retaining structure of the middle inner barrel and the wall of the middle outer barrel. When the motor vibrates in an operating process, as the motor is fixed in the middle inner barrel and the annular fit clearance exists between one end of the middle inner barrel and the middle outer barrel, vibration transferred to the middle outer barrel will be weakened, so that vibration of the middle outer barrel is reduced, bolt looseness and desoldering of a welded junction generated by vibration of the middle outer barrel are avoided, continuous operation of the sprayer is guaranteed and the work efficiency of the sprayer is improved.

Description

technical field [0001] The invention relates to a spray machine air cylinder. Background technique [0002] The process of urban development is accompanied by a large number of demolition and construction, and a large amount of dust will appear in the process of demolition and construction. These dusts will cause the deterioration of the environment and even cause the occurrence of smog. The water can be turned into mist through the spray dust suppression device. Combine with fine dust particles in the air to reduce the dust content in the air; while the air duct in the spray dust suppression device is a key component for turning water into water mist and transporting water mist, but the air duct will generate blast during operation Friction creates noise and vibration. [0003] In the Chinese utility model patent whose authorized notification number is CN206325763U, a spray and dust-suppressing blower device is provided. The blower includes a frustum-shaped front barrel, a...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sprayer blower, which is used to solve the problem in the prior art that the working efficiency of the sprayer becomes low due to the vibration of the motor, which causes the bolts to loosen or the welding joint to be desoldered.
