The second weighing platform 50 closes the second blanking port 12. The second bracket 52 is driven by the second linear module 53 located outside the material storage chamber 1. The second bracket 52 slides laterally, so The second load sensor 51, the second drive motor 31, and the second linear module 53 are all electrically connected to the control system. By setting the dial, the dial includes a plurality of evenly distributed paddles, so that every time the dial rotates a certain angle, a certain amount of feed can be sent from the left side of the feed channel to the right side of the feed channel, and then dropped to the third At the first feeding port, the weight is recorded by the first weighing device, which can quickly complete rough quantitative feeding. The feed is ground at the second feeding port, and the ground feed falls on the second weighing sensor. According to the required amount of feed and the weight recorded by the first weighing device, the amount of feed required by the second weighing sensor is obtained, and a more precise quantitative supply is provided through the second feeding port. When the amount of feed reaches After setting the amount, the second weighing slider assembly is moved through the second linear module, so that the material can be quantitatively fed quickly and accurately. In addition, through grinding, some animals that do not have the ability to chew in their infancy can eat feed. Furthermore, when it is necessary to feed medicine to pets, on the one hand, the grinding device and the weighing device can accurately supply the medicine; on the other hand, the Medication mixed in the feed is easier for pets to absorb.

As a further preferred embodiment, the paddle 21 is provided with a chute 211, and the chute 211 is provided with a spring 23 and a scraper 22. The scraper 22 is slidingly connected to the chute 211, and the spring 23 The scraper 22 is provided with an outward thrust. This ensures that the dial is always in close contact with the cavity wall of the powder feeding channel during rotation, and the feed will not be unable to be delivered due to falling in the gap between the paddle and the cavity wall, and the amount of feed transferred each time will be greater. for stability.

As a further preferred embodiment, it also includes an air injection device, the air injection device includes a first air pump, and the first air pump is connected to the first blanking port 11 through an air pipe. By arranging the air jet device, when the dial is rotating and cannot rotate due to the densely packed feed, the air can be sprayed into the first feeding port to disturb the tightly packed feed, thereby returning the tightly packed feed to a looser state. status, so that the dial wheel can move the feed normally.
