Description

Pet automatic feeding and feeding mechanism

technical field

The invention relates to the field of pet feeding, in particular to an automatic feeding and feeding mechanism for pets.

Background technique

Pets have become partners in people's daily life, and feeding pets is an important item to take care of pets. At present, there are many automatic pet feeding equipment on the market, which can realize the automatic feeding of pet feed, and even realize quantitative feeding of feed more accurately. Most of the discharging mechanisms in the prior art use a rotary or sliding type for material distribution and discharging. The so-called rotary type means that a rotating shaft is rotated at the discharge port at the lower end of the grain storage bin, and the outer wall of the rotating shaft is provided with a concave for accommodating the feed. When the groove opening faces the grain storage bin, the feed in the grain storage bin can be accommodated in the groove. With the rotation of the rotating shaft, when the groove opening is downward, the feed in the groove can be discharged; the so-called sliding type It means that a slider is slidably connected to the discharge port at the lower end of the grain storage bin, and the slider is provided with a through hole for accommodating feed. When the through hole is located directly below the discharge port at the lower end of the grain storage bin, the feed in the grain storage bin can be It slides into the through hole, and the bottom of the through hole is pressed by another baffle plate, so the feed in the through hole will not leak. If the feed in the hole loses the restraint of the baffle plate, the feed in the through hole will be discharged from the lower end opening. The automatic feeding action of the feed can be realized through the above two methods, but there is a common problem: the general feed is granular, such as dog food. Many dog food on the market are round or five-pointed star, or even some Special-shaped structure, then in the process of automatic discharge, that is, when the shaft rotates, the edge of the rotary groove and the edge of the discharge port of the grain storage bin are often stuck by the granular feed, resulting in unsmooth discharge; or, When the slider slides, the edge of the upper opening of the sliding through hole and the edge of the discharge port of the grain storage bin will also be clamped by granular feed, resulting in unsmooth discharge. To sum up, the current automatic pet feeding equipment has the phenomenon that the material is not smooth enough.
