A pneumatic opening and closing system of an ore hopper car comprises a pair of bottom door pneumatic operating valves and a bottom door opening and closing two-way air cylinder. The pair of bottom door pneumatic operating valves are respectively arranged on two sides of a floor of the ore hopper car; the bottom door opening and closing two-way air cylinder is arranged on a floor of the ore hopper car, a first piston and a first push rod are arranged in the bottom door opening and closing two-way air cylinder, one end of the first push rod is connected with the first piston, and the other end of the first push rod penetrates through the end of the bottom door opening and closing two-way air cylinder and is connected with the bottom door mechanical transmission device. The pneumatic opening and closing system of the ore hopper car comprises a pair of bottom door pneumatic operating valves and a bottom door opening and closing two-way air cylinder, the pair of bottom door pneumatic operating valves are arranged on the two sides of a floor of the ore hopper car respectively, and an operator can conduct pneumatic operation on the bottom door pneumatic operating valves when standing on the ground of any side of the ore hopper car. The problem that in the prior art, an operator can only get on a vehicle to conduct pneumatic unloading operation and cannot stand on the ground flush with the rail to conduct pneumatic unloading operation is effectively solved.

    一种矿石漏斗车风动开闭系统,包括一对底门风动操作阀和底门开闭双向气缸;一对底门风动操作阀分别设于矿石漏斗车的地板两侧;底门开闭双向气缸设于矿石漏斗车的地板上且底门开闭双向气缸内设有第一活塞和第一推杆,第一推杆的一端与第一活塞相连接,另一端穿过底门开闭双向气缸的端部并与底门机械传动装置相连接。本发明的矿石漏斗车风动开闭系统包括一对底门风动操作阀和底门开闭双向气缸,一对底门风动操作阀分别设于矿石漏斗车的地板两侧,操作人员站在矿石漏斗车的任一侧的地面上均可对底门风动操作阀进行风动操作,有效解决了现有技术中操作人员只能上车进行风动卸货操作,无法站在与轨道平齐的地面进行风动卸货操作的问题。
