All-dimensional regulating device for air outlet of fully mechanized excavation face air cylinder

The invention discloses an all-dimensional regulating device for an air outlet of a fully mechanized excavation face air cylinder. The all-dimensional regulating device comprises the air cylinder, a bracket and a guide rail. The air inlet end of the air cylinder is in rotation connection with one end of the bracket, a sliding block is installed at the other end of the bracket. The guide rail is internally provided with a front-and-back pushing mechanism. A rotation driving mechanism is installed between the bracket and the pushing sliding block. A vertical regulating mechanism is hinged to the part between the air cylinder and the bracket. A plurality of tapered fan blades are hinged to the air inlet of the air cylinder, and a conical structure is formed by the multiple tapered fan blades. Blade regulating hydraulic cylinders are fixed to the outer wall of the air cylinder, the number of the blade regulating hydraulic cylinders is equal to the number of the tapered fan blades, each tapered fan blade correspon
