[0002] Rabbits are widely used as experimental animals and play a unique role in the field of medical research. Feed impurity removal equipment is used to remove impurities, foreign matter and unclean substances from animal feed. It can ensure the quality and purity of feed, thereby improving the health and growth efficiency of animals. During the processing of experimental rabbit feed, impurity removal equipment is needed to remove impurities from pellet feed.

[0003] According to Chinese patent application No.: 202320672337.1, a feed impurity removal device with intelligent filtration is disclosed, including a bottom box, the top of the bottom box is connected to a processing box, the inner cavity of the processing box is provided with a crushing roller, the inner cavity of the bottom box is provided with a conveyor belt, and the surface of the bottom box is fixedly connected with a first motor. By arranging the bottom box, the processing box, the crushing roller, the conveyor belt, the first motor, the guide inclined plate, the heating block, the U-shaped plate and the magnet, a feed impurity removal device with intelligent filtration is jointly constructed, wherein the feed is broken up by the crushing roller, and the iron filings and other debris inside the feed can be completely exposed, and then the feed is transmitted through the conveyor belt. At the same time, during the transmission process, the feed is dried by the heating block to prevent the moisture in the feed from sticking the feed together and making it inconvenient for the subsequent impurity removal, thereby improving the quality and work efficiency of the feed, and finally the feed is transmitted to the magnet to adsorb the metal objects in the feed to achieve the effect of impurity removal;
