The invention discloses a lower hopper ridge of a hopper car. The lower hopper ridge of the hopper car is made of aluminum alloy materials, and adopts an integrally molded structure. The lower hopper ridge comprises a lower transverse ridge, a connecting part, a supporting part and stiffening beams, wherein the lower transverse ridge comprises two side plates, and one ends of the side plates are fixedly connected in an acute angle; the connecting part comprises two connecting plates, and one ends of the connecting plates are respectively and fixedly connected with the other ends of the two side plates; an included angle between the two connecting plates is larger than that between the two side plates; the supporting part comprises two supporting plates arranged oppositely, and the two supporting plates are respectively and fixedly connected with the other ends of the two connecting plates. Through the adoption of the lower hopper ridge of the hopper car, the dead weight of the lower hopper ridge can be greatly lowered under the situation that the operating requirements of the lower hopper car are met, the improvement of the loading of the car is facilitated, and the lower hopper ridge solves the technical problem that because a lower hopper ridge in the prior art adopts a steel welded structure, the dead weight of the lower hopper ridge is large, and the lower hopper ridge is adverse to the improvement of the loading of the car.
