By setting two guide plates 28, the pet food between the two guide plates 28 can be blocked during the rotation of the grain distribution plate 24 to prevent the pet food from staying on the grain distribution plate 24 and unable to fall.

[0039] In order to facilitate the installation and removal of the grain receiving tray 22, a positioning slot 29 is opened on the inner wall of the bottom shell 2 of the feeder, and a positioning card 210 is fixedly installed on the grain receiving tray 22. The positioning card 210 is movably installed in the positioning slot 29. Pushing the grain receiving tray 22 downward can drive the positioning card 210 to disengage from the positioning slot 29, thereby removing the grain receiving tray 22.

[0040] In order to facilitate the disassembly and assembly of the grain storage barrel 31, a mounting ring 36 is fixedly installed on the grain storage barrel 31, and two first arc-shaped buckles 37 are fixedly installed on the mounting ring 36. Two positioning grooves 38 are provided on the inner wall of the grain barrel docking groove 3, and the two positioning grooves 38 are respectively adapted to the two first arc-shaped buckles 37. First arc-shaped snap-on grooves 39 are provided in the two positioning grooves 38. The two first arc-shaped buckles 37 are respectively movably buckled in the two first arc-shaped buckle grooves 39. The grain storage barrel 31 is rotated so that the grain storage barrel 31 drives the two first arc-shaped buckles 37 on the mounting ring 36 to disengage from the buckling with the two first arc-shaped buckle grooves 39. Continuous rotation makes the two first arc-shaped buckles 37 slide to the two positioning grooves 38. At this time, the grain storage barrel 31 can be pulled to remove it from the grain barrel docking groove 3 on the feeder housing 1.

[0041] In order to prevent the limit card plate 49 from loosening, two linear buckle grooves 411 are provided on the inner wall of the feeder bottom shell 2, and the two linear buckle grooves 411 are movably buckled with bar buckles 412. The two bar buckles 412 are respectively fixedly installed on both sides of the limit card plate 49. When the limit card plate 49 is inserted into the limit card groove 410, the movement bottom shell 41 can be restricted from rotating to prevent the movement bottom shell 41 from loosening. At this time, the two linear buckle grooves 411 and the two bar buckles 412 are in a buckled state to prevent the limit card plate 49 from detaching.

[0042] In order to facilitate the disassembly and assembly of the movement housing 42 and the movement bottom housing 41, two second arc-shaped snap grooves 413 are opened on the inner wall of the installation groove 4, and the two second arc-shaped snap grooves 413 are movably snapped with second arc-shaped buckles 414. The two second arc-shaped buckles 414 are fixedly installed on the movement housing 42. By rotating the movement bottom housing 41, the movement bottom housing 41 will drive the two second arc-shaped buckles 414 to disengage from the snap connection with the two second arc-shaped snap grooves 413, and vice versa, the snap-connection and installation operation can be realized.

[0043] In order to enable the grain discharging shaft 45 to drive the grain discharging plate 24 to rotate when docking with the grain discharging plate 24, and not interfere with the grain discharging plate 24 when removing the grain discharging plate 24, a plurality of limiting grooves 415 are provided on the inner wall of the connecting groove 46, and a limiting plate 416 is movably installed in the limiting groove 415, and the limiting plate 416 is fixedly installed on the grain discharging shaft 45, and a plurality of T-shaped grooves 417 are provided on the grain discharging shaft 45, and a T-shaped bar 418 is movably installed in the T-shaped groove 417. 18 is fixedly installed on the inner wall of the connecting groove 46. When the grain discharging shaft 45 rotates, it will drive the grain distributing plate 24 to rotate through the cooperation of the limiting groove 415, the limiting plate 416, the T-slot 417 and the T-bar 418. When the grain discharging shaft 45 is removed, the grain discharging shaft 45 will be separated from the connecting groove 46 and drive the limiting plate 416 to be separated from the limiting groove 415 on the grain distributing plate 24. At the same time, the T-slot 417 on the grain discharging shaft 45 will be separated from the T-bar 418 in the connecting groove 46.

[0044] In order to further save storage space, the feeder shell 1 is adapted to the inner wall of the grain barrel docking groove 3. When not in use, the grain storage barrel 31 can be opened to store the entire feeder shell 1 and internal components in the grain storage barrel 31, which can also save transportation space.

[0045] The working principle is as follows: the cover plate 34 is opened to expose the desiccant tray 310, which can be used to place desiccant. The movable buckles 35 on both sides are flipped to separate it from the connecting frame 32, so as to release the restriction on the connecting frame 32. The grain storage barrel 31 can be opened by pulling the connecting frame 32, and the pet food can be poured into the grain storage barrel 31 through the connecting frame 32 or directly poured into the grain storage barrel 31 for storage after opening the connecting frame 32. The pet food will fall into the guide inclined plate 26, and then fall into the corresponding grain distribution trough 25 in the grain inlet trough 23 through the drop opening 27 and the two guide plates 28. When feeding is needed, the motor 44 is turned on, and the output shaft of the motor 44 drives the grain outlet shaft 45 to rotate. The rotating grain discharging shaft 45 will drive the grain distributing plate 24 to rotate, and the rotating grain distributing plate 24 will drive the pet food in the grain distributing trough 25 to move until the grain distributing trough 25 corresponds to the position of the discharging nozzle 21, and the pet food will fall into the grain receiving plate 22 through the discharging nozzle 21 for the pet to eat. By setting two guide plates 28, the pet food between the two guide plates 28 can be blocked during the rotation of the grain distributing plate 24 to prevent the pet food from staying on the grain distributing plate 24 and unable to fall. The grain storage barrel 31 is a detachable structure, and the grain storage barrel 31 can be directly rotated to remove it from the grain barrel docking groove 3 on the feeder shell 1. The movement bottom shell 41 and the movement shell 42 are detachable designs, and the limit card plate can be pushed 49, the limiting card plate 49 will drive the two strip buckles 412 to disengage from the buckling with the two straight buckle grooves 411, and at the same time, the limiting card plate 49 will disengage from the limiting buckle groove 410, thereby releasing the rotation restriction on the movement bottom shell 41, and then rotating the movement bottom shell 41, the movement bottom shell 41 will drive the two second arc buckles 414 to disengage from the buckling with the two second arc buckle grooves 413, and then pull the movement bottom shell 41, the movement bottom shell 41 will drive the movement shell 42 to be pulled out of the installation groove 4, the movement bottom shell 41 and the movement shell 42 will drive the motor 44 and the grain discharging shaft 45 to be pulled out of the installation groove 4, and the grain discharging shaft 45 will be disengaged from the connecting groove 46 on the grain distributing plate 24, so that the entire driving structure It is separated from the bottom shell 2 of the feeder, and the grain receiving tray 22 can be removed by pushing it downward. At this point, the driving structure is completely separated from other parts, and the electronic components: circuit board 43, motor 44, photoelectric switch 419, battery 420, speaker 421, communication module 422 and sensor 48 are all installed on the bottom shell 41 of the movement and are removed with it, so that the remaining parts such as the grain storage barrel 31, grain receiving tray 22, etc. can be cleaned. If there are parts in the driving structure that are damaged, they can also be removed separately for repair, saving transportation space. When not in use, the grain storage barrel 31 can be opened to store the entire discharge structure and the driving structure in the grain storage barrel 31, which can also save transportation space.
