Novel spray head of pulp shooting machine

Abstract

The invention provides a novel spray head of a pulp shooting machine, and belongs to the technical field of pulp shooting operation. Comprising a connecting pipe, a spray head seat and a spray head pipe, the connecting pipe is communicated with the spray head seat through a first connecting flange, the spray head seat is communicated with the spray head pipe through a second connecting flange, a water inlet pipe is communicated with the spray head seat, and a water inlet valve is fixedly installed on the water inlet pipe. A water tank is formed in the nozzle base, and a water inlet hole communicating with the interior is formed in the inner wall of the water tank. By arranging the water inlet holes, a water adding cylinder can be formed during water adding, the mixing time is prolonged, the mixing space is lengthened, full contact and mixing of water and a dry mixture of sand, stone and cement are achieved, dry cement small particles which are not wetted by water and contained in sprayed concrete materials are greatly reduced, dust is greatly reduced, and the water adding efficiency is improved. And during spraying, springback materials are reduced, and the spraying surface strength is improved.

Description

technical field [0001] The invention relates to the technical field of shotcrete work, in particular to a new spray head of a shotcrete machine. Background technique [0002] The shotcrete machine is an indispensable mechanical equipment for the roadway shotcrete construction. Its function is to fully stir the shotcrete such as cement, yellow sand, and stones to form a qualified shotcrete material, and use the high-pressure air flow to spray the shotcrete material to the roadway surface. Forms a reinforced surface. In the daily shotcrete construction process, a large amount of dust is generated on site. Through the actual observation of the site shotcrete operation, the fundamental reason for the large amount of dust generated by the shotcrete machine is that the shotcrete cannot be effectively wetted, which not only causes the shotcrete The material ratio cannot fully meet the requirements, the quality of the shotcrete is reduced, the shotcrete operation is laborious and t...

Problems solved by technology

In the daily spraying construction process, a large amount of dust is produced on site. Through the actual observation of the site spraying operation, the root cause of the large amount of dust produced by the spraying machine is that the spraying material cannot be effectively wetted, which not only causes the spraying The ratio of materials cannot fully meet the requirements, the quality of spraying is reduced, the spraying operation is laborious and time-consuming, and the dust generated will cause physical damage to operators
