The first feed port 13 is located on the upper side of the first feeding barrel 11, and the first discharge port 14 is located on the lower side of the second feeding port. Preferably, the first discharge port 14 is located at the first opening of the shell 4. The driving part 31 can be a motor, and the driving part 31 drives the transmission part 32 to rotate through gear transmission. The stirring rod 21 is fixed to the second feeding barrel 12, and the driving part 31 drives the transmission part 32 to rotate, driving the second feeding barrel 12, the stirring rod 21, the first set of blades 22 and the second set of blades 23 to rotate, so that the powders in the first accommodating chamber 110 and the second accommodating chamber 120 are in motion to prevent the powders from piling up and agglomerating. The second set of blades 23 are pressed against the screen 5, and the second set of blades 23 stir the powders to prevent the powders from piling up and agglomerating, and can also press the powders to fall downward through the screen 5. The amount of powder discharged can also be controlled by controlling the stirring speed of the second set of blades 23.
