This invention discloses a railway hopper car for transporting powdery goods, relating to the technical field of railway hopper cars. It includes a car body, a pneumatic
control system, a coupler buffer device, an air braking device, a manual braking device, and a
bogie. A
hydraulic control system is located at the lower part of the car body. The car body includes a
chassis, with two hoppers with double-sealing structures at the bottom of the
chassis. The two hoppers are distributed on both sides of the
chassis's central beam. Two side walls are provided on both sides of the chassis, with end walls at each end of the side walls. A roof is provided above the side walls and end walls. A
discharge port is provided at the bottom of the hoppers, and a flip-up bottom door with a two-stage locking device is provided at the
discharge port. The roof includes a fixed top cover
assembly and a movable top cover
assembly positioned directly above the fixed top cover. This invention has a reasonable design and solves the problems of the side walls not balancing strength and space, top cover jamming, easy accidental opening of the bottom door, and poor sealing in hopper cars.
