A discharging baffle 16 is fixedly connected to the middle side of the lower portion of the outer cylinder 12.
[0027] Through structures such as the outer cylinder 12, a metering port 14 is provided in the upper portion of the metering cylinder 13. Materials flow into the metering port 14 through the feeding and discharging ports 15 and then enter the metering cylinder 13. The metering cylinder 13 is driven by the third motor 6 to rotate 180°. Then, it is discharged through the discharging baffle 16 of the feeding and discharging port 15. If it is necessary to adjust the volume of feeding and discharging, the length of the regulating cylinder 9 inside the metering cylinder 13 can be controlled by the telescopic movement of the electric telescopic rod 7, so as to adjust the discharging volume. With the help of structures such as the metering cylinder 13, the metering structure can accurately measure the amount of required materials, and the volume adjustment is realized through the regulating cylinder 9.
[0028] Refer to Figures 5-6 , An upper portion of the box body 1 is fixedly connected with a screening cylinder 2.

The materials are discharged into the box body 1 through the screening holes 17, while impurities or materials larger than the screening holes 17 remain inside the screening cylinder 2. When there are too many impurities or materials inside the screening cylinder 2, the screening cylinder 2 is detached from the box body 1, and the materials or impurities inside the screening cylinder 2 are poured out to avoid damage to the metering cylinder 13.
[0030] Working principle: First, with the cooperation of structures such as the sieve cylinder 2, the material enters through the funnel 3. Driven by the first motor 4, the stirring rods 19 on the rotating rod 18 stir the material in the sieve cylinder 2.
