The utility model provides a detection device of concrete homogeneity. The device comprises a container, wherein the container is a tank body with a fan-shaped cross section and an open top; a plurality of layered openings are equidistantly formed in a plane plate at one end of the container from top to bottom; a water injecting nozzle is inwards arranged at the center of the bottom of the container; the two plane plates are connected by virtue of a hollow cylinder; a solid cylinder which is concentric to the hollow cylinder is arranged in the hollow cylinder; a plurality of arc-shaped openings are equidistantly formed in the hollow cylinder from top to bottom; the number of the arc-shaped openings is the same as that of the layered openings, wherein the corresponding two openings are positioned in the same plane; a plurality of lugs are connected onto the solid cylinder and respectively extend out of the hollow cylinder from the corresponding arc-shaped openings; one side of each lug, facing the layered openings, is connected with one side of a sieve plate; the sieve plate can be used for driving the lugs to rotate around the solid cylinder. The detection device is simple in structure, simple and convenient to operate and short in detection period.
