[0024] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a particle size sorting device for feed processing, including a frame 1. Multiple screening mechanisms 2 are slidably connected from top to bottom inside the frame 1. A linkage mechanism 3 is provided between each adjacent screening mechanism 2. The linkage mechanism 3 includes two rack rods 301 and two gears 302. The gears 302 are rotatably connected to the inner wall of the frame 1.

One of the screening mechanisms 2 is swung back and forth using a sliding mechanism. This screening mechanism 2 uses the cooperation of rack and pinion 301 and gear 302 to make the other screening mechanisms 2 slide back and forth together, thus improving the screening and filtering efficiency of the screening mechanism 2.

[0029] By rotating the threaded rod 6, the movable end of the threaded rod 6 is inserted into the slot 7, thereby fixing the screening frame 4 in the mounting slot cavity on the mounting bracket 5.

A connecting rod 14 is fixedly connected to one side of the slip ring 13. The movable end of the connecting rod 14 is fixedly connected to one side of the bottom mounting bracket 5.

[0036] like Figure 1 - Figure 3 As shown, a servo motor 15 is installed on the frame 1. The movable shaft of the servo motor 15 is fixedly connected to the axis at the bottom of the turntable 11. The servo motor 15 is electrically connected to the power supply.
