Powder output device capable of automatically controlling discharge amount

The invention discloses a powder output device capable of automatically controlling the discharge amount. The powder output device comprises a funnel-shaped powder cylinder and a feeding device communicating with the bottom of the powder cylinder. A mounting frame is mounted on the lower portion of the powder cylinder in a hoisting mode. One end of the feeding device is fixedly mounted on the mounting frame, and the other end of the feeding device is connected with a fixing frame and communicates with a mixing device. A tension sensor is mounted between the feeding device and the fixing frame. The mass of the feeding device is measured and controlled through the tension sensor, and the tension sensor can precisely control the powder conveying amount of the feeding device, improve the proportion precision of mixed powder and improve the quality of concrete production. The automation degree is high, the labor cost can be reduced, and resources are saved. 本发明公开了种可自动控制排放量的粉料输出装置，包括呈漏斗状的粉料筒，以及与粉料筒底部连通的送料装置，粉料筒的下部吊
