Mixed-spraying type concrete sprayer

The utility model discloses a mixed-spraying type concrete sprayer and belongs to the technical field of engineering machinery in drilling soil layers or rocks. The mixed-spraying type concrete sprayer comprises a water spraying portion and a material spraying portion and is characterized by further comprising a filament spraying portion, and water, materials and filaments are jointly sprayed out through the water spraying portion, the material spraying portion and the filament spraying portion. Materials of concrete, river sand, the water and the filaments can be effectively mixed together to form sprayed concrete to be sprayed on a slope surface of shoring engineering, the slope surface of the shoring engineering is further strengthened, and the situations of frequent falling off and cracking of sprayed concrete layers on the slope surface of the shoring engineering can be avoided. Compared with the prior art, the mixed-spraying type concrete sprayer has the advantages of simple structure, reliable performance, convenience in operation, high operation efficiency and the like.
