[0028] Working principle of the utility model: During use, the medicament falls into the storage box 5 directly below through the hopper 8. At this time, the medicament can be weighed by the pressure sensor 4. When the amount of medicament in the storage box 5 reaches a certain level, the first motor 10 drives the gear 12 to rotate at this time. The gear 12 drives the rotating shaft 11 to rotate, so that the rotating shaft 11 drives the turntable 2 to rotate. The turntable 2 drives the support 3 and the storage box 5 to rotate. When the turntable 2 rotates, the turntable 2 drives the rotating ring 14 to rotate in the rotating groove 13 at this time. The rotating ring 14 plays a supporting role for the turntable 2. The second motor 19 drives the screw 20 to rotate at this time. The screw 20 drives the second slider 21 to move in the second chute 18 at this time. The second slider 21 drives the corresponding storage box 5 to move, so that the blanking pipe 6 on the storage box 5 can move outside the housing 1. Then, the solenoid valve on the blanking pipe 6 is opened, so that the medicament in the storage box 5 can fall to the appropriate position through the corresponding blanking pipe 6, thus completing the quantitative feeding of the medicament.
