description The utility model discloses a dust fall device for fully-mechanized coal mining, which relates to the technical field of fully-mechanized coal mining, and comprises a base in the shape of a flat box with an open top surface, the upper end surface of the base is connected with a pair of toothed plates in a sliding manner, a pair of first center rods are arranged between the pair of toothed plates, the outer wall of each first center rod is rotatably sleeved with a first gear, and the pair of first gears are meshed with each other; the outer wall of each first gear is meshed with the inner side of the corresponding toothed plate, the upper end face of each toothed plate is fixedly connected with a rectangular frame, and a rectangular block is arranged in each rectangular frame. The air cylinder pushes the toothed plate to slide in a reciprocating mode, the toothed plate drives the other toothed plate to slide synchronously in the same direction through the pair of first gears, and therefore the corresponding at
