FIELD: construction.;SUBSTANCE: invention relates to construction, namely to devices for ejection a mortar or a concrete mixture onto mold pallets, to form thin-walled structures, and can also be used for low-rise construction, for applying a mortar or concrete mixture on the finishing surfaces (external and internal parts of buildings and structures) in any coordinates. Sluice ejector for shotcreting includes: a body (sluice) including a shell, two sidewalls and additionally the base, which passes into the nozzle of the mixture to the sluice chamber; the shell has an open aperture along the rotor rotation path for ejection the mixture.;EFFECT: technical result of the invention are: improvement of the device in order to increase productivity and continuity of the working cycle; the use of an electric drive (or another type of drive) and ensuring an ejection rate of the mixture of more than 80 meters per second; application of mixtures of different plasticity (rigidity) and their application to the treated surfaces in any coordinate.;3 cl, 4 dwg
