A water mixer structure,The system includes a floating platform,One agitates the impeller and one electric motor.The floating platform can float on a water surface.The electric motor is arranged above the floating platform.And the driving shaft system of the electric motor can pass through the holding platform.And the front end of the drive shaft is connected to the disc body of the agitated impeller.A plurality of agitated blades with through holes are arranged on the periphery of the disc body.And the front end of each agitated blade extends outwards at a certain angle with a leading edge blade with a through hole.When the electric motor operates,Part of the water below the water surface can pass through the first through hole of the agitating blade and the second through hole of the leading edge blade.So that the water eddy generated by the rotation of the agitated impeller can diffuse to the periphery.And in the course of continuous rotation,The water eddy that diffuses to the surrounding edge flows upward and inward.So as to produce a vortex flow that does not contact or agitate the bottom sediment below the water surface.一種耘水機結構,係包含一浮台、一攪動葉輪及一電動馬達,其中該浮台能夠漂浮於一水面上,其中該浮台上方具有該電動馬達,而該電動馬達之驅動軸係能夠穿過該容置平台、並將該驅動軸前端連接於該攪動葉輪之盤體上,該盤體周緣係側立有數個具有穿透孔之攪動葉片,而每一個攪動葉片前端更以一定角度向外側延伸出有一具有穿透孔之前緣葉片,其中該電動馬達運作時,該水面下方的部分水流能夠穿過該攪動葉片之第一穿透孔及該前緣葉片之第二穿透孔,使該攪動葉輪轉動所產生的水渦流能夠向周緣擴散出去,並於持續轉動的過程中,將向周緣擴散出去的水渦流向上向內捲起,以使產生水渦流不至於向下接觸或攪動水面下方底面的泥沙。
