Background

The concrete spraying machine is widely applied to protection engineering machines such as tunnels, culverts, subways, bridges, coal mines, high-biogas mines, hydropower engineering, underground engineering, constructional engineering and the like, is divided into three types of dry type, wet type and semi-wet type according to different water adding methods of concrete mixture, and is divided into a dry type concrete spraying machine, a wet type concrete spraying machine and a dry-wet type two-purpose spraying machine according to different construction processes.

The concrete in the concrete spraying machine passes through the hopper, the rotor body reaches the cyclone of the spraying machine, and then is sprayed to a construction area through the spray head after passing through the spraying pipe, but the service life of the spraying pipe is not high due to the fact that the spraying pipe is directly connected with the cyclone, the spraying pipe of the spraying machine is inclined downwards after being connected with the cyclone, a corner is formed at a place which is contacted with the ground, the inner wall of the spraying pipe at the corner is impacted by concrete sand stones greatly, the surface of the pipe wall is worn relatively quickly, a quick wear area is formed at the place, the spraying pipe is characterized in that only one part of the spraying pipe is worn out, the concrete is broken out quickly under a relatively large pressure, the whole pipe is scrapped, the service life of the first spraying pipe connected with the spraying machine is not very high, meanwhile, the construction cost of the material waste construction party is increased after the pipe is broken, the first spraying pipe discharged by the spraying machine is mostly worn out, the whole spraying pipe is replaced relatively frequently, and the construction is frequently replaced, and the part is frequently replaced, so that the part is frequently replaced. This forms the waste of material and has increased very big expense for the constructor, and then causes construction cost to increase, and the pipeline that breaks easily exists the potential safety hazard, because of the quick wearing and tearing district of the first root guniting pipe of guniting machine ejection of compact is very near from the guniting machine, when this is worn out, the concrete grit thick liquids can be sprayed out from the breach and hurt the constructor of machine operation very easily, so this also brings certain potential safety hazard for the workman.
