摘要： The present invention discloses a large-volume grain hopper car suitable for a low-loading position hopper bin. The grain hopper car includes a car body; a loading opening of the car body is provided with a top cover opening and closing mechanism, the top cover opening and closing mechanism includes a top cover and a transmission shaft, the transmission shaft is located inside the car body, the transmission shaft is connected to a top cover driving mechanism, the transmission shaft is hinged to a crank throw, and the crank throw is hinged to the top cover. The beneficial effects of the present invention are as follows: According to the grain hopper car, the arrangement of the top cover opening and closing mechanism is innovated in order to improve the volume of the car, and the transmission shaft, which is conventionally disposed on the car roof for opening and closing the top cover, is disposed in the internal space of the car body in such a way that the upper space of the car roof is utilized to the maximum extent, and the distance between the car roof and the upper limit is closest, so that the volume of the car is improved under the condition of the same car length, and the loading capacity of the whole train is improved; besides, by translating or sliding the top cover, the occupancy of the upper space in the opening process of the top cover is decreased, thus the grain hopper car is suitable for a station yard with the low-loading position hopper bin condition.
