Discharging opening of high-speed mixer

The utility model relates to the technical field of mixing machine feed openings. The high-speed mixer feed opening comprises a main frame body, a mixing box body is erected on the top of the main frame body, a sealing door is hinged to the top of the mixing box body, a strip-shaped stirring shaft is transversely erected in the mixing box body through a bearing, and a control panel is installed on one side of the mixing box body. And a servo motor is fixed at the position of the other side of the mixing box body. Through the design of the anti-blocking mechanism in the feed opening, the connecting belt at the output end of the servo motor can drive the first rotating shaft to rotate, and the other group of connecting belts can drive the second rotating shaft and the third rotating shaft which is in meshed connection with the second rotating shaft through the driven gear and the driving gear to synchronously rotate; and therefore, materials discharged through the discharging opening can pass through the second
