FIELD: underwater ground mining. SUBSTANCE: ground intake of suction-tube dredger has suction head, ejector head with central ejecting nozzle, ejector with nozzle and mixing chamber and diffuser. Ejector head is communicated with mixing chamber through successively installed receiving chamber and collector. Suction head is double-flow. Both flows are symmetrically connected to side surface of receiving chamber. Ejector head with central ejecting nozzle is installed between flows and coaxially connected to receiving chamber. Ejector nozzle is located on central axis of mixing chamber. EFFECT: higher efficiency. 2 dwg
