FIELD: underwater mineral mining. SUBSTANCE: hydraulic agitator of suction-tube dredger consists of manifold in form of fixed pipe with nozzles installed on suction ground intake and water supply pipeline connected to manifold. Located inside manifold is pipe for rotation relative to manifold. Inner pipe is communicated with water supply pipeline. Uniformly arranged on inner pipe over circumference are ports for coincidence with nozzles during rotation of inner pipe. Length of each port is determined by relation given in invention description. Inner pipe is rotated by drive. EFFECT: higher efficiency. 2 cl, 3 dwg
