The invention discloses a bottom door flow control device for a railway stone ballast hopper car, which comprises a limiting baffle plate, a supporting seat, a plurality of pin holes and supporting pins, wherein one end of the limiting baffle plate is connected with a transmission shaft swing block of a middle bottom door of the railway stone ballast hopper car, a supporting seat which is arranged on one side of the limiting baffle plate and is provided with a plurality of pin holes at intervals from top to bottom, and supporting pins which can be inserted into the pin holes; when the limiting baffle rotates along with the transmission shaft swing block, the supporting pin can interfere with the other end of the limiting baffle to limit the rotating angle of the limiting baffle and the transmission shaft swing block, the multiple pin holes and the supporting pin form multiple gears to control the opening degree of the middle bottom door, and therefore the purpose of controlling the flow of the middle bottom door is achieved, operation is easy, and application is reliable. The whole device is simple in structure and is common parts, the number of machining parts is small, manufacturing and purchasing are convenient, and cost expenditure is effectively saved.

    本发明公开了一种铁路石砟漏斗车用底门流量控制装置,包括:限位挡板,一端与铁路石砟漏斗车中间底门的传动轴摆块连接,支撑座,设置于限位挡板的一侧,支撑座上由上至下间隔设置有多个销孔,支撑销,能够插设于销孔内,当限位挡板随传动轴摆块转动时,支撑销能够与限位挡板的另一端干涉,限制限位挡板和传动轴摆块的转动角度,该装置通过多个销孔和支撑销构成多个档位控制中间底门开度,从而达到控制其流量的目的,操作简单、运用可靠,整个装置结构简单,且均为常用件,机加工减件少,方便制造采购,有效地节省了成本支出。
