The invention discloses a discharge pipe of a rotary vibration screen. A feed port connected with a screen body is formed in one end of the discharge pipe, and a discharge port for discharging materials is formed in the other end; the feed port is connected with the discharge port through a connecting pipe; a material plate, forming the top of the connecting pipe, is provided with bends from the center to two sides; and the bends are provided with projections in the center of the material plate in the length direction. The discharge pipe of the rotary vibration screen is reasonable in design and convenient to use, improves overall strength and beauty of the discharge port, meanwhile, facilitates discharge, and improves the production efficiency.
