ンクリート投射装置。 In a centrifugal concrete projection device in which concrete material is input from the outside of a plurality of blades rotating in a vertical plane, and the concrete is projected in the circumferential direction by centrifugal force by the rotating blades, each blade of the rotating blades The body is formed into a serrated shape in the direction of rotation between a pair of parallel rotating plates, and the tooth-shaped cross section is
It is formed into a roughly isosceles triangular shape with both hypotenuses in the rotation direction bulging outward in a curved shape, and the curvature of the curve is such that the rotation radius from the rotation center is the same as the protrusion direction tip and base end. It is constructed so that the concrete material changes sequentially according to a certain law between the two ends of the base of the blade, and the concrete material is thrown toward the center of rotation, collides with the curved surface of the blade, and then is reflected in a certain direction. A centrifugal concrete projection device characterized by the following configurations.
