[0002] Feed is a general term for all foods needed by farmed animals. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains and feed additives.

[0003] After the feed is produced, it needs to be screened to screen out the unqualified feed. In the existing patent CN219540899U, it is disclosed that by setting a rotating rod, a fixed plate, an electric telescopic rod, a connecting rod, a rotating block, and a fixed block, it is achieved to prevent the position of the screen plate from being blocked due to large feed, and avoid the inability to perform normal screening due to feed accumulation;

[0004] However, the above patent still has certain problems. For example, since the position of the feed port is fixed, the feed can only fall on a small part of the filter plate corresponding to the feed port after passing through the feed port, which results in no feed falling into other positions of the filter plate, thereby reducing the utilization rate of the filter plate. Utility Model Content

[0009] Preferably, the fixing frame is in contact with the interior of the collecting bin, and two baffles for blocking feed are fixedly connected to the top surface of the fixing frame;

[0010] Among them, the side of the baffle away from the self-locking motor is an inclined surface.

[0012] Preferably, the feeding device comprises two sliders, which are respectively slidably connected to the inside of the corresponding slide groove, and the slider close to the threaded rod is threadedly sleeved on the threaded rod;

[0013] The opposite surfaces of the two sliders are fixedly connected with a mounting frame for installation, a feed box is fixedly installed inside the mounting frame, and a plurality of discharge pipes with electric control valves are fixedly installed at the output end of the feed box, and the discharge ends of the discharge pipes penetrate the mounting frame;
