In order to realize the function, the side wall of the feeding channel corresponds to the shape of the dial, so that by setting the dial, the dial includes a plurality of evenly distributed paddles, so that every time the dial rotates a certain angle, it can move a certain amount of material. The feed is sent from the left side of the feeding channel to the right side of the feeding channel, and then falls to the first feeding port to complete quantitative feeding.

As a further preferred embodiment, the paddle 121 is provided with a chute 1211. The chute 1211 is provided with a spring 123 and a scraper 122. The scraper 122 is slidingly connected to the chute 1211. The spring 123 The scraper 122 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 111 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.

As a further preferred embodiment, the material storage chamber 11 further includes a second material discharge port 112 . The second material discharge port 112 is provided with a grinding device 13 and a second drive motor for driving the grinding device 13 . 131.

The second weighing slide block assembly includes a The second weighing platform 150, the second load sensor 151, and the second bracket 152 are arranged and connected together. The second weighing platform 150 closes the second blanking port 112, and the second bracket 152 is driven by the second linear module 153 located outside the material storage cavity 11, and the second bracket 152 slides laterally. Combined with the dial wheel provided at the first blanking port, the dial wheel includes a plurality of evenly distributed paddles, so that every time the dial wheel 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. side, and then falls to the first feeding opening. The weight is recorded by the first weighing device, which can quickly complete rough quantitative feeding. The feed is ground at the second feeding opening, and the ground feed falls into the third feeding opening. On the second load cell, based on the required amount of feed and the weight recorded by the first weigher, the amount of feed required by the second load cell is obtained, and a more precise quantitative supply is provided through the second drop port. , when the feed amount reaches the set 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 second powder falling channel 114 is also provided with a fine blanking slider 140, and the fine blanking slider 140 is provided on the upper side of the second weighing slider assembly.
