A large-volume grain hopper car suitable for a low-loading hopper bin, comprising a car body (1). A top cover opening and closing mechanism (2) is arranged at a loading opening of the car body; the top cover opening and closing mechanism comprises a top cover (21) and a transmission shaft (22); the transmission shaft is located inside the car body, and is connected to a top cover drive mechanism; the transmission shaft is hingedly connected to a crank throw (212); the crank throw is hingedly connected to the top cover. According to the grain hopper car, in order to improve the volume of the car and innovate the arrangement of the top cover opening and closing mechanism, the transmission shaft for opening and closing the top cover traditionally arranged on a roof is arranged inside the car body, and the upper space of the roof is utilized to the maximum extent, so that the roof is closest to the upper clearance, the volume of the car can be improved under the condition of the same car length, and the loading capacity of the whole car is improved. The occupation of the upper space in the opening process of the top cover is reduced by means of translation or sliding of the top cover, and the hopper car is suitable for a station yard condition of the low-loading hopper bin.
