Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically a screening device for shrimp feed production. Background Technology

[0002] In shrimp feed production, the feed varies in size. Screening can effectively remove substandard raw materials and classify shrimp feed of different sizes, thus meeting the needs of farmers for high-quality feed.

[0003] The prior art, disclosed in patent document CN216574198U, presents the following technical solution: a feed pellet screening and grading device for feed production, comprising a box body, a feeding hopper at the top of the box body, a stirring device inside the feeding hopper, an opening at the lower end of the feeding hopper extending into the box body, a first screen on the upper side of the box body, a second screen on the lower side of the box body, a vibrating motor at the bottom center of both the first and second screens, and slow-falling baffles between the front and rear side walls of the box body and above the first and second screens. The advantage of this invention compared to the prior art is that it incorporates a paddle-type stirrer inside the feeding hopper to break up clumps of feed entering the hopper, preventing them from entering the box body in block form and affecting the screening effect.

[0004] The above-mentioned technical solution installs a stirring device in the feed hopper to break up clumps of feed. However, when the feed is poured into the feed hopper, the space between two adjacent stirring rods becomes full of feed. As the feed falls through the rotating rod, the breaking up effect is generally poor. Furthermore, the gap between the stirring rod and the feed hopper may cause clumps of feed to slip away.
