Embodiment Construction

[0008] Such as figure 1 , 2 Shown, at first original two door leaves on the compartment are removed, and two rows of wicket 2 are installed on the long side of door frame 1, and wicket 2 and door frame 1 link into one. The other edge of two rows of wicket 2 intersects and contacts in the middle of door frame 1, to seal the door opening of loading. The shape of wicket 2 is the elastic plate body of the rectangle with radian, and the radian of two rows of wicket 2 is downward, and wicket 2 is made with saw blade steel band, to guarantee enough permanent elasticity is arranged. The method for adjusting the elastic strength of the wicket 2 is to select saw blade steel strips of different thicknesses for processing.

[0009] When loading, the coal leaks from the hopper of the sky warehouse. The gravity of the coal will open the small door 2 outward, and the small door 2 will be elastically deformed. The coal will rush through the small door and fall into the carriage. Return to ...

Abstract

A door leaf of a bell-type boxcar is provided with an automatic opening and closing function, and structurally comprises two rows of small doors. One edge of each small door is fixedly connected to the side face of a door frame, the other edges of the small doors are in crossed contact with one another in the middle of the door frame so as to seal a door opening for loading, and each small door is provided with a downward radian and made of saw-blade steel strips so that sufficient lasting elasticity is guaranteed. The small doors are automatically opened outwardly under the action of gravity of coal when loading, and reinstate under the action of deforming elasticity after loading is stopped.
