A door opening and closing device of a transport line for a bottom-dump hopper car is provided according to the present application, which includes a striker device configured to open and close a bin gate of the bottom-dump hopper car, and a lifting device mounted to a 5 base. The lifting device includes a lifting component, and the lifting component has an articulated end articulated to the base and a support end configured to support the striker device. In the case that the lifting component rotates by a preset angle with respect to the base, the support end is configured to raise or lower the striker device to a respective preset position. The door opening and closing device uses the rotation of the lifting device to change the 10 height of the striker device, has a simple structure, and can control the lifting height of the striker device by controlling the rotating angle, thus the operation of the door opening and closing device is convenient. Therefore, the door opening and closing device not only can be applied to the transport line for the bottom-dump hopper car, but also can allow other types of vehicles to pass through the railway track by lowering the striker device after the unloading is 15 completed, thereby greatly improving the adaptability of the railway track. 6504608_1 (GHMatters) P99991.AU ADAMD Fig. 9 o o Fig. 10
