The invention provides a bottom door opening and closing device and a hopper car. The bottom door opening and closing device comprises a driving device and a transmission device. The transmission device comprises a bearing seat, a transmission shaft and a transmission self-locking structure; the transmission shaft is rotationally connected with the bearing seat, and the transmission self-locking structure comprises a push rod and a driven rod which are arranged on the transmission shaft; the first end of the push rod is fixedly connected with the transmission shaft, the second end of the push rod is hinged to one end of the driven rod, and the other end of the driven rod is used for being connected with a bottom door. The driving device is used for driving the transmission shaft to rotate so as to drive the bottom door to be opened and closed through the driven rod; and the driven rod comprises a bending part, and when the driven rod rotates until the first end of the push rod is in contact with the inner concave surface of the bending part, the push rod forms a self-locking state. According to the hopper car and the bottom door opening and closing device thereof, the opening and closing speed and unloading efficiency of the bottom door can be improved, and meanwhile safety is improved.
