The invention discloses a duplex multi-door-hole grain hopper car bottom door which comprises a bottom door frame assembly, a plurality of discharging holes are formed in the bottom door frame assembly, a sliding bottom door plate assembly is arranged on the bottom door frame assembly, and a plurality of material passing holes are formed in the bottom door plate assembly. A discharging hole formed by the bottom door frame and a material passing hole formed by the bottom door plate are opposite or staggered to achieve through discharging or closed material blocking. The door further comprises a roller device and a driving device, the roller device supports the sliding motion of the bottom door plate assembly in a rolling mode, and the driving device drives the bottom door plate assembly to slide between the door closing position and the door opening position. The bottom door has the beneficial effects that the bottom door is simple in structure, the unloading area is increased through the multi-door-hole bottom door, and the unloading efficiency is improved; meanwhile, through a simple mechanical sealing mode, the sealing performance of the bottom door is guaranteed, and small-particle goods such as rapeseeds cannot be leaked when being transported; the bottom door is simple in structure, convenient to maintain and composed of the drawer type short-stroke bottom door, the stroke of the air cylinder is short, and the bottom space of the grain hopper car is saved.
本发明公开了一种复式多门孔粮食漏斗车底门,包括底门框组成,底门框组成上设有若干下料孔,底门框组成上设有滑移运动的底门板组成,底门板组成上设有若干过料孔,底门框组成的下料孔与底门板组成的过料孔相对或相错实现贯通卸料或封闭挡料;还包括辊轮装置和驱动装置,辊轮装置滚动支撑底门板组成的滑移运动,驱动装置驱动底门板组成在关门位与开门位之间滑移运动。本发明的有益效果:此底门结构简单,多门孔底门增大了卸货面积,提高了卸货效率;同时,通过简单的机械式密封方式,保障了底门的密封性能,在运输油菜籽等小颗粒货物时不会泄露;此底门不仅结构简单,便于维护,抽屉式短行程底门组成,气缸行程短,节约了粮食漏斗车底部空间。
