[0032] Example 1: Refer to Figures 1-6This is the first embodiment of the present invention, which provides a screening device for animal feed additives. During processing and packaging, animal feed additives need to be screened to avoid packaging large particles, which would affect the packaging effect. Additionally, screening animal feed additives can easily clog the screening mesh, thus affecting the screening effect of the device. The device includes a screening mechanism 1, which includes a screening hopper 101. The screening hopper 101 is located at the top of the screening mechanism 1, and a door panel body 1 is hinged to one side wall of the screening hopper 101. 02. An L-shaped support frame 104 is installed at the top of the screening hopper 101, and a drive motor 105 is installed at the bottom of the L-shaped support frame 104. The output end of the drive motor 105 is connected to a drive shaft 106 via a coupling. A scraper body 108 is installed at the bottom of the outer wall of the drive shaft 106. Fixing plates 107 are installed on the side walls at both ends of the screening mechanism 1. A first groove 1010 is opened at the bottom of the screening hopper 101. A first threaded hole 1011 is opened at the bottom of the screening hopper 101. An installation groove 1012 is opened on the side walls at both ends of the interior of the screening hopper 101. A screening mesh body 1013 is installed inside the installation groove 1012.

[0033] Each scraper body 108 has a brush body 109 installed at its bottom end, and the bottom end of the brush body 109 is in contact with the top end of the screen body 1013. A handle body 103 is installed on the side wall of one side of the door panel body 102, and a rubber sleeve is installed on the outer wall of the handle body 103. Each screening mechanism 1 has a limit rod 111 installed at its top end, and the limit rod 111 is engaged with the first groove 1010.

[0034] The installation and disassembly mechanism 2 includes a rotating rod 201, which is rotatably mounted on a positioning plate 202 via a bearing. A positioning block 204 is installed on the side wall of one end of the positioning plate 202. A pressing plate 205 is provided at one end of the positioning block 204.
