The invention relates to an U-shaped fluidized feed port. The U-shaped fluidized feed port comprises a container shell and a feed port; the feed port is formed in the container shell, and is providedwith a sleeve; a fluidized feed pipe is aslant arranged in the sleeve; the fluidized feed pipe comprises an U-shaped fluidized pipe, a nonmetal expansion joint, a striding joint and a fluidized chute;one end of the U-shaped fluidized pipe is fixedly connected into the sleeve, and the other end of the U-shaped fluidized pipe is connected with the nonmetal expansion joint; the left end of the fluidized chute is connected with the striding joint; a through hole is formed in the inner side of the nonmetal expansion joint; the striding joint is fixedly arranged in the through hole; a fluidized surface is arranged on the inner side of the U-shaped fluidized pipe, and is arranged between the sleeve and the nonmetal expansion joint; an U-shaped ventilation surface can blow fluidized air into theU-shaped fluidized pipe; and the fluidized air can loosen materials, and feeds the loosened materials into a storage tank or a storage bin in a spraying state, so that the blockage problem of a discharge port is effectively solved.
