Air splitting type spouting head

Abstract

The invention provides an air splitting type spouting head. The air splitting type spouting head comprises a connecting pipe, a nozzle, an air mixing pipe and an air mixing pipe sleeve. An annular groove formed in the air mixing pipe and the air mixing pipe sleeve form an amplification chamber, the amplification chamber, a side opening in the air mixing pipe sleeve and amplification holes in the annular groove form an amplification channel, secondary power is provided through the amplification channel, the spouting strength of the nozzle is improved, the spouting distance is increased, accelerating agents are injected into the air mixing pipe through the amplification channel, and filling of the accelerating agents is convenient. Through the holes formed around the annular groove and inclined inwards, air and the accelerating agents can enter the air mixing pipe easily, the phenomenon that the air flows back can be avoided, and the accelerating agents can be uniformly mixed with spouted materials. The nozzle is made of elastic rubber materials, so that the blockage phenomenon of common metal nozzles is avoided, when slurry is partially blocked, the pressure of the blockage part is increased, the slurry is automatically spouted when the pressure is increased by a certain value, the nozzle does not need to be disassembled, material leakage is prevented in the spouting process, and raw materials are saved.

Description

technical field [0001] The invention belongs to the field of spraying equipment, in particular to an air-distributing type spraying head. Background technique [0002] Shotcrete is a support method widely used in the construction of mine roadways, various tunnels, underground buildings and high-rise building foundation pits. As an important part of the spraying equipment, the spraying head is an important part of the spraying equipment, and its design mechanism directly determines the effect and quality of the spraying. quality. Commonly used spraying heads in engineering, such as patent number: 201520638643.9, named as the spraying head of multi-functional mixing pile driver; Defects include: uneven spraying, slurry leakage, clogging and anti-wind phenomenon. These defects will directly affect the quality of the project, waste resources and reduce work efficiency. Contents of the invention [0003] In order to solve the problems of uneven spraying, slurry leakage, clogg...
