[0050] Please refer to Figures 1 to 6 An embodiment of the present invention provides a vacuum feeder, including a feeding hopper 1 and a grain discharging rotating disk 2.

[0051] Among them, the unloading hopper 1 has an inverted cone-shaped loading surface 11, thereby forming a storage space, and a unloading hole 12 is opened on the loading surface 11; the grain discharge rotating disk 2 is installed on the bottom side of the unloading hopper 1, and is provided with a discharge hole 21; the grain discharge rotating disk 2 can rotate around the center line of the unloading hopper 1 so that the discharge hole 21 is aligned with or staggered from the unloading hole 12; comb-tooth-like screening combs 22 are provided on the hole walls on both sides opposite to the unloading hole 12, and the comb teeth of the screening comb 22 are in contact with the top surface of the grain discharge rotating disk 2, and the extension line of the surface of one side of the comb-tooth-like structure passes through the rotation center line of the grain discharge rotating disk 2.

[0052] When the discharging rotating disk 2 rotates relative to the discharging hopper 1, the screening comb 22 can push the granulated pet food to the discharging hole 12 for discharging, and the crumbs and powdered pet food remain on the top surface of the discharging rotating disk 2, that is, the screening comb 22 cannot completely push the crumbs and powdered pet food, thereby effectively reducing the amount of crumbs and powdered pet food falling into the food bowl, which is equivalent to reducing the output of crumbs pet food.

[0053] Specifically, when the grain discharging rotating disk 2 rotates to the first set rotation angle, the pet food falls onto the top surface of the grain discharging rotating disk 2 along the discharge hole 12, and then the grain discharging rotating disk 2 rotates relative to the discharge hopper 1, so that the pet food on the grain discharging rotating disk 2 is pushed into the discharge hole 21 by the screening comb 22 for discharge. In the process of the pet food being pushed, the crumbs and powdered pet food pass through the gaps of the screening comb 22 and remain on the grain discharging rotating disk 2, thereby reducing the outflow of crumbs and powdered pet food and avoiding excessive crumbs from accumulating on the grain bowl of the vacuum feeder.

[0054] Optionally, the vacuum feeder is further provided with a slag suction device for sucking the slag on the grain discharging rotating disk 2; the slag suction device includes a suction device and a slag suction pipe that can extend to the top surface of the grain discharging rotating disk 2, and the slag suction pipe is connected to the suction device. When the material discharging hole 21 and the material discharge hole 12 are completely staggered, the end of the slag suction pipe extends into the top surface of the grain discharging rotating disk 2, and the slag suction device sucks the slag on the top surface of the grain discharging rotating disk 2, thereby recovering the pet food in the form of slag.

[0055] Optionally, the vacuum feeder also includes a rotating shaft 3 and a rotating drive device 4 for driving the rotating shaft 3 to rotate, the rotating shaft 3 passes through the grain discharge rotating disk 2 and the feeding hopper 1 in sequence from bottom to top, and the center line of the rotating shaft 3 coincides with the rotation center line of the grain discharge rotating disk 2; the grain discharge rotating disk 2 is fixedly connected to the rotating shaft 3, and a stirring element 5 for stirring the pet food in the feeding hopper 1 is installed at the top of the rotating shaft 3.

[0056] Specifically, the stirring member 5 stirs the pet food in the discharge hopper 1 so that the pet food can fall into the discharge hole 12, making the discharge of the pet food more stable.

[0057] Optionally, the stirring member 5 includes a dome portion 51 and a stirring rod portion 52 connected to the dome portion 51; the bottom surface of the stirring rod portion 52 is lower than the bottom surface of the dome portion 51, and the distance between the bottom surface of the stirring rod portion 52 and the loading surface 11 is greater than the maximum particle size of the pet food. Specifically, the dome portion 51 structure can make it easier for the pet food to slide into the feeding hole 12, and the stirring rod portion 52 extends outward, so that more pet food can be stirred to avoid the situation where the pet food is piled up and does not move. The distance between the bottom surface of the stirring rod portion 52 and the loading surface 11 is greater than the maximum particle size of the pet food, which can avoid crushing the pet food.

[0058] Optionally, the bottom surface of the stirring member 5 is parallel to the loading surface 11, and the top surface of the stirring member 5 is a convex arc surface. It should be particularly noted here that the feeding hopper 1 has an inverted cone-shaped loading surface 11, and the bottom surface of the stirring member 5 is parallel to the loading surface 11, so that the effect of stirring the pet food can be better, that is, the pet food can more easily enter the feeding hole 12 along the inverted cone-shaped loading surface 11.

[0059] Optionally, the vacuum feeder also includes a storage barrel 6; the storage barrel 6 has a conical bucket portion 61 and a cylindrical barrel portion 62, the cylindrical barrel portion 62 and the conical bucket portion 61 are connected, and the unloading hopper 1 and the food outlet rotating disk 2 are both installed in the barrel-shaped space of the cylindrical barrel portion 62; the pet food in the conical bucket portion 61 slides into the space in the storage barrel 6 under the action of gravity.

[0060] The bottom surface of the food discharging rotating disk 2 is in contact with the bottom wall of the cylindrical barrel portion 62, and the bottom wall is provided with a slide-out hole 601 that can be connected to the discharging hole 21. Specifically, after the pet food falls into the feeding hole 12, the food discharging rotating disk 2 continues to rotate under the drive of the rotary drive device 4, so that the slide-out hole 601 and the discharging hole 21 are connected to each other, so that the pet food slides out for the pet to eat. When the pet food just enters the discharging hole 21, the slide-out hole 601 and the discharging hole 21 are staggered with each other.

[0061] Optionally, the grain discharge rotating disk 2 includes a main disk body 201 and a limiting disk 202 embedded in one side of the bottom of the main disk body 201; the limiting disk 202 is provided with an arc-shaped groove 203 around the rotation center line of the grain discharge rotating disk 2, and a limiting column 602 extending into the arc-shaped groove 203 is provided on the bottom wall of the barrel; when the limiting column 602 abuts against the groove wall at one end of the arc-shaped groove 203, the discharge hole 21 is aligned with the discharge hole 12; when the limiting column 602 abuts against the groove wall at the other end of the arc-shaped groove 203, the discharge hole 21 and the discharge hole 12 are completely staggered, and the grain discharge rotating disk 2 closes the discharge hole 12.

[0062] Specifically, in this embodiment, the rotation of the discharge rotating disk 2 is limited by the limit column 602, and the rotation drive device 4 controls the rotation angle of the discharge rotating disk 2 by driving the discharge rotating disk 2 to rotate forward or reverse.

[0063] Optionally, two rotating shafts 3 are provided, and each rotating shaft 3 is equipped with a feeding hopper 1 and a food discharging rotating disk 2, and a transmission gear is installed on the rotating shaft 3; the rotating driving device 4 includes a rotating motor and a driving gear installed on the output shaft of the rotating motor, and the driving gears are respectively engaged with the transmission gears. Specifically, the discharging rotating disk 2 in this embodiment can drive the two rotating shafts 3 to rotate at the same time, thereby controlling the two feeding hoppers 1 to discharge pet food.

[0064] Optionally, the vacuum feeder further comprises a support seat 7 for supporting the material storage barrel 6 and a grain barrel seat 8 for supporting the support seat 7. The support seat 7 and the grain barrel seat 8 form a grain outlet flow channel, and the grain outlet flow channel is connected to the slide-out hole 601.

[0065] Optionally, the grain barrel seat 8 is further provided with a grain bowl 9 for holding pet grain, and the grain bowl 9 is the final resting place of the pet grain, that is, the pet grain falls on the grain bowl 9 after passing through the feeding hole 12, the grain discharging rotating disk 2, the discharging hole 21, the sliding hole 601, and the grain discharging flow channel.

[0066] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
