Quantitative feeding device

The utility model discloses a quantitative feeding device which comprises a fixing frame, a third rotating shaft and a first rotating shaft are rotationally connected in the fixing frame, a driving belt wheel is fixedly connected to the outer side of the third rotating shaft, a driven belt wheel is fixedly connected to the outer side of the first rotating shaft, and the driving belt wheel is in transmission connection with the driven belt wheel through a belt. The semiconductor conveying device has the advantages that semiconductors can be conveyed through the belt, the semiconductors fall into the containing grooves, the second rotating shaft is rotated to drive the rotating disc to move, the semiconductors can be conveyed through the belt, the semiconductors can be conveyed through the belt, and the semiconductors can be conveyed through the rotating disc. Therefore, semiconductors in the placing groove fall on the guide plate through the discharging groove, automatic feeding is achieved, the working effici
