The invention relates to an automatic folding type flap gate of a construction lifter. The automatic folding type flap gate is characterized in that the lower flap gate of the flap gate is pivoted to the bottom of a lifting cage through a flap gate shaft; an upper slide door is mounted on the upper portion of the lifting cage and can move up and down along the lifting cage; a foldable retaining plate is pivoted to the top of the lower flap gate, and the lower flap gate, the foldable retaining plate and the upper slide door are sequentially disposed from bottom to top; one end of a steel wire rope is connected to the upper slide door, and the other end of the steel wire rope is connected to the lower flap gate and winds on an upper fixed pulley and a lower fixed pulley; a connecting rod is respectively pivoted to the foldable retaining plate and the bottom of the lifting cage through connecting rod pins and can push the foldable retaining plate to turn. The automatic folding type flap gate has the advantages that the problem that a feeding platform (walkway) needs to be built on each layer of the construction lifter is solved, the problem that the lower flap gate size is hard to select when the construction lifter is close to a building outer wall is solved, the lower flap gate cannot be opened if the lower flap gate is too large, and a cage door cannot be completely sealed after closing if the lower flap gate is too small is solved, and the application range of the construction lifter using the flap gate type lifting cage is expanded.
