The invention discloses a rotary bottom door of a railway hopper car, which relates to the technical field of bottom doors of railway hopper cars and comprises two bottom door components, a bearing mounting seat component, a transmission shaft component, a hydraulic cylinder and a hydraulic cylinder mounting seat. The two bottom door assemblies are symmetrically arranged on the two sides of the transmission shaft assembly and movably connected with the transmission shaft assembly. The bearing installation seat assemblies are arranged at the two ends of the transmission shaft assembly and connected with the transmission shaft assembly through fasteners. The hydraulic cylinder mounting base is fixed to the middle beam assembly, one end of the hydraulic cylinder is connected with the hydraulic cylinder mounting base in a hinged mode, and the other end of the hydraulic cylinder is connected with the transmission shaft assembly in a hinged mode; the transmission shaft assembly is provided with a locking device which is matched with the secondary locking mechanism to prevent the bottom door from being opened accidentally. By adopting the transmission mechanism passing through the dead point, the bottom door has a self-locking function, and the bottom door is prevented from being accidentally opened. The hydraulic control system is adopted to drive the bottom door to be opened and closed, and special ground facilities are not needed.
