Spraying device who sprays structure and have this injection structure

The utility model discloses a spraying device who sprays structure and have this injection structure sprays the structure, including the nozzle, with the nozzle is connected, is used for mix the mixed structure of at least first material and second material around the nozzle, and go mixed structure carries the transport structure of each material respectively. Spraying device includes the spray gun, to the material feeding mechanism of material is supplied with to the spray gun, and foretell injection structure, the material feeding mechanism with transport structure is connected. The utility model provides a current spray technique to stir into the liquid coating with coating powder and water mixture, leading -in spray gun carries out the spraying again, the engineering time is long, the inefficiency, the condense technical problem of quick coating of unable spraying, it does not need earlier that whitewashed and water mixes the stirring, spray time weak point, efficiency of construction height, but the effect that quick coating is condensed in the spraying to coating at other devices to have.
