The invention relates to a non-uniform inflow channel type propeller which comprises a guide pipe, a stator assembly is installed on the front portion in the guide pipe, a rotor assembly is installed on the rear portion in the guide pipe, and the guide pipe is a through pipe body with the large front portion and the small rear portion and comprises a first pipe body and a second pipe body which are connected front and back. The distance between the top face of the first pipe body and the axis of the second pipe body is smaller than the distance between the bottom face of the first pipe body and the axis of the second pipe body. The stator assembly is located in the first pipe body, and the rotor assembly is located in the second pipe body. The stator assembly comprises a stator hub, stator blades are installed on the outer wall face of the stator hub at intervals in the circumferential direction, and the density degree of the stator blades distributed on the upper portion of the outer wall face of the stator hub is larger than that of the lower portion. Therefore, the guide pipe is matched with the stator assembly to jointly form a non-uniform inflow channel, so that non-uniform inflow flows are converted into uniform fluid through the non-uniform inflow channel and then flow into the rear rotor assembly, and the whole propeller has smaller non-steady exciting force and higher propelling efficiency.
