The invention discloses a sand suction device for sand excavation of a self-sand-discharging ship, and relates to the technical field of sand excavation ships, the sand suction device comprises a water cutting machine and a water cutting pipe fitting, and the water cutting pipe fitting is installed at the bottom of the water cutting machine. According to the sand suction device for sand excavation of the self-sand-discharging ship, the specific positioning and mounting position of the seam control ring is adjusted on the conical head through threads, rotary type annular water jet cutting of sand pebbles in different ranges is achieved, and the sand pebbles with high hardness and large blocks on a riverbed can be intensively cut and crushed; according to the sand suction device, piled sand pebbles on a riverbed can be subjected to centralized crushing treatment, the tolerance of a notch and the sand pebbles on the riverbed during crushing is improved, the sand pebble crushing effect of the crushing disc is imp
