[0002] Fish and shrimp feed have certain requirements for crushing particle size during the production process, so the requirements for screening equipment are higher. Most of the existing screening devices use a vibration motor to drive the screen plate to vibrate synchronously, which plays a role in turning and transporting the material. However, the power amplitude of the vibration motor is constant, the turning efficiency is low, and the material is easily stuck in the screen hole, which affects the screening efficiency and makes it troublesome to clean up later. An aquatic feed grinder disclosed in announcement number CN214636794U can play an anti-blocking role to a certain extent by setting a knocking anti-blocking component under the screen plate, but like the vibration motor, it is an indirect anti-blocking role with poor anti-blocking effect.

[0023] The rear end of the rotating shaft 2 extends out of the rear end face of the shell 1. A second motor 9 is fixed to the lower side of the rear end face of the shell 1. The second motor is a servo motor. The second motor 9 drives the rotating shaft 2 to rotate 30° periodically in forward and reverse directions through a gear connection.
[0024] The left and right ends of the sieve plate 3 are respectively provided with arc-shaped plates 10, which are fixedly connected to the left and right end faces of the shell 1. The axis of the arc-shaped plate 10 is coaxial with the rotating shaft 2. The arc-shaped plate 10 can prevent the material on the upper side of the sieve plate 3 from falling through the left and right sides of the sieve plate 3. The left and right ends of the sieve plate 3 are respectively fixed with arc-shaped slide plates 11, and the outer edge surface of the slide plate 11 is in contact with the inner edge surface of the arc plate 10. The slide plate 11 can prevent the material from entering the matching gap between the arc plate 10 and the sieve plate.
[0025] The front and rear ends of the sieve plate 3 are respectively fixed with a transverse slide bar 12, and the left and right ends of the slide bar 12 are fixedly connected to the lower end face of the sieve plate 3 through a connecting rod. The front and rear ends of the cleaning roller 4 are respectively rotatably connected with a slider 13, and the slide bar 12 passes through the left and right end faces of the slider 13 and is slidably connected to the slider 13; the front and rear sides of the lower end face of the sieve plate 3 are respectively fixed with a transverse rack 14, and the front and rear ends of the cleaning roller 4 are respectively coaxially fixed with a gear 15, and the gear 15 is engaged with the rack 14.
