The invention discloses a combined type grid bottom door device and a wagon hopper car. The combined type grid bottom door device comprises a bottom door frame and a movable bottom door, wherein the movable bottom door can slide in the bottom door frame. The combined type grid bottom door device is installed between an end wallboard and a middle hopper. In this way, the defect of the prior art that space occupied by a bottom door and a hopper of a hopper car in a car body is large, and therefore the using volume of the car can not be increased is overcome, and the unloading efficiency of the large-opening-degree hopper car is improved.
