description The invention relates to a coal mine fully-mechanized excavation face cone-shaped body flow guide and air regulation device which comprises a cylindrical pipe, a conical pipe and an air baffle for blocking compressed air flow, the air baffle comprises a base connected to an inner cavity of a circular truncated cone body in a sliding mode and a plurality of fan blades distributed in the circumferential direction of the base and hinged to the base, and the adjacent fan blades are connected through fan cloth. The side face, close to the air pressing barrel, of the circular truncated cone is provided with an annular gap allowing the fan blades to penetrate out and communicating with an inner cavity of the circular truncated cone, and the cylindrical pipe is provided with an air flow opening located between the air baffle and the air pressing pipe. When the fan is used, the base is driven to move opposite to the pressure air flow, the fan blades and the fan cloth are driven by the base to move opposite to the pres
