The invention discloses a rapid powdered material discharging and receiving port which comprises a hollow chassis, and a hollow supporting plate fixed on the upper part of the hollow chassis through an extension spring, wherein a sealing ring is arranged on the upper part of the hollow supporting plate; an elastic washer is arranged on the hollow supporting plate between the sealing ring and a central hole of the hollow supporting plate; a round pipe matched with the central hole of the hollow supporting plate is arranged on the lower part of the hollow supporting plate; a blanking pipe is arranged in a central hole of the hollow chassis and fixed at the bottom of the hollow chassis through a flange fixed on the upper part of the blanking pipe and a bolt running through a flange bolt hole; the blanking pipe and the round pipe are connected through a corrugated hose. According to the rapid powdered material discharging and receiving port disclosed by the invention, the problem that the existing discharging joint is difficult to butt and poor in sealing property can be effectively solved, the discharging and receiving port can be rapidly butted with a discharge opening, the sealing property is high, and materials are difficulty to leak.
