The invention discloses a railway hopper car which comprises a hopper, an underframe, a bogie, a brake device, a coupler buffer device and a bottom door opening and closing device, a longitudinal opposite-opening inner-unloading type bottom door is arranged at the bottom of the hopper, and the longitudinal opposite-opening inner-unloading type bottom door comprises a first bottom door body and a second bottom door body which are symmetrically arranged in the longitudinal direction; the outer side edge of the first bottom door and the outer side edge of the second bottom door are hinged edges, and the inner side edge of the first bottom door and the inner side edge of the second bottom door are oppositely arranged; and the bottom door opening and closing device is mounted at a bottom discharge port of the funnel and is used for driving the longitudinal oppositely-opened inner discharge type bottom door to be opened or closed. According to the railway hopper car, the bottom door opening and closing device is arranged at the end of the bottom door, and the driving shaft is perpendicular to the length direction of the bottom door and is arranged at the end of the bottom door, so that the problems that in the prior art, a longitudinal hopper ridge needs to be arranged in a car body due to the fact that a longitudinal transmission shaft needs to penetrate through a car body unloading area are fundamentally solved, and the cargo carrying space of the funnel is occupied.

    本发明公开了一种铁路漏斗车,包括漏斗、底架、转向架、制动装置、车钩缓冲装置和底门开闭装置,漏斗的底部设置有纵向对开内卸式底门,纵向对开内卸式底门包括沿纵向对称设置的第一底门和第二底门,第一底门的外侧边和第二底门的外侧边均为铰接边,第一底门的内侧边与第二底门的内侧边相对设置;底门开闭装置安装在漏斗的底部卸料口处,用于驱动纵向对开内卸式底门开启或关闭。本发明提供的铁路漏斗车,通过将底门开闭装置设置于底门的端部,且主动轴垂直于底门的长度方向、设置于底门的端部,从而从根本上消除现有技术因纵向传动轴需要贯通车体卸货区域,因此在车体中需要有纵向漏斗脊,挤占漏斗的载货空间的技术问题。
