10. The upward grain handling mechanism of claim 9, wherein the drive assembly comprises a drive motor and a drive gear coupled to a drive shaft of the drive motor, and wherein an outer ring gear engaged with the drive gear is provided on an outer peripheral surface of the outer disc.

11. The pet feeder is characterized by comprising a grain barrel and the upward grain conveying mechanism of claim 9 or 10, wherein the grain conveying tray is arranged in the grain barrel, and a discharge hole is formed in the top of the side wall, close to the grain conveying tray, of the grain barrel.

12. The pet food dispensing device of claim 11, wherein said spout has a closed position and an open position;

in the blocking state of the material guiding opening, the material guiding opening is staggered with the material discharging opening, and the material guiding opening is blocked, so that pet food in the grain storage bin can be kept in the grain storage bin;

in the open state of the material guiding port, the material guiding port is communicated with the material discharging port, so that pet food in the grain storage bin can fall to the outside of the grain bucket through the material guiding port and the material discharging port.

13. The pet feeder of claim 12, further comprising a face housing vertically mounted within the barrel, the face housing having a mounting cavity, the tray being mounted within the mounting cavity, a side of the face housing remote from the center of the barrel being of an open configuration, the tray abutting against a side wall of the face housing proximate the center of the barrel, a side of the bin on which the spout is disposed abutting against an inner wall of the barrel to enable the spout to be blocked by the inner wall of the barrel;

the face shell is close to the bottom of the side wall of the center of the grain barrel and is provided with a communication port, and the communication port is communicated with the material through port and the grain barrel.
