The invention discloses a railway hopper car unloading device. The railway hopper car unloading device comprises at least one set of bottom door assembly and control mechanisms. The bottom door assemblies are arranged at a bottom discharging outlet of a hopper bin, and the control mechanisms are used for controlling opening and closing of the bottom door assemblies. Each bottom door assembly is composed of two bottom doors which are symmetrically arranged relative to the car body longitudinal center. The multiple corresponding bottom doors on same side of the bottom discharging outlet of the hopper bin are controlled to be opened and closed by the same set of control mechanisms. The control mechanisms open the corresponding bottom doors on any one side or two sides so that goods in the hopper bin can be completely unloaded. By means of the railway hopper car unloading device, the same set of control mechanisms control the multiple bottom doors on the same side of the bottom discharging outlet of the hopper bin to be opened and closed at the same time, transmission efficiency is high, the whole structure is compact, and unloading efficiency is greatly improved; moreover, one-sided unloading can be achieved or simultaneous two-sided unloading can be achieved, and one-sided complete unloading can be achieved.
