The invention discloses a hopper car sealing type bottom door which comprises a bottom door frame and a bottom door body and further comprises a sliding way, wherein the bottom door body is arranged on the sliding way in a sliding mode, the bottom door frame makes contact with and is attached to the bottom door body, the supporting height of a supporting part on the sliding way is gradually increased in the closing direction, and/or the lifting height of a lifting part of the bottom door body is gradually increased in the opening direction. Through contact combination of three rollers, a bottom door plate and a sealing adjusting plate, automatic change of a gap between the bottom door body and the bottom door frame during opening and closing of the bottom door body is achieved. The sealing performance of the bottom door is effectively improved, the inertia problems of rain and snow infiltration and cargo leakage caused by structural gaps of the bottom door of the hopper car are solved, and the manufacturing difficulty and the maintenance cost are reduced.

    本发明公开了一种漏斗车密封式底门,包括底门框和底门,还包括滑道,底门滑动设在滑道上,底门框与底门接触贴合,滑道上支撑部的支撑高度沿关闭方向逐渐增高,和/或底门的托举部的托举高度沿开启方向逐渐增高。本发明通过三个滚轮与底门板、密封调整板之间的接触组合,实现底门开启、关闭时与底门框间隙的自动变化。有效提高底门密封性,解决了既有漏斗车底门因结构缝隙,导致的雨雪渗入、货物泄漏惯性问题,且降低制造难度及维护成本。
