The invention discloses a self-unloading transfer carrier. The carrier comprises a bottom frame, four stand columns are fixedly connected to the bottom frame, and the four stand columns are located at the four top corners of the bottom frame correspondingly; a dustproof cover is buckled to the top ends of the stand columns, an unloading plate is slidably connected to the interior of the bottom frame through a sliding rail, the unloading plate abuts against an unloading opening, a plurality of buffer layers are arranged between the unloading opening and the dustproof cover, each buffer layer comprises a buffer strip, the two ends of each buffer strip are fixedly connected with supporting rods, the supporting rods are perpendicular to the buffer strips, and the supporting rods are erected between the stand columns; a protective flexible plate made of anti-static PVC fiber canvas is hung between every two stand columns, and an observation window is arranged on each protective flexible plate; the end, close to the dustproof cover, of each protective flexible plate is provided with a fixing assembly, and the fixing assemblies are used for fixing the relative positions between the protective flexible plates and the stand columns; and the end, close to a discharging opening, of each protective flexible plate is fixedly connected with the discharging opening. According to the carrier, the effect of improving the bearing capacity is achieved.
