[0002] Rice, also known as rice, is a food made from rice grains after cleaning, husking, milling, and finishing. Rice is the main food for people in most parts of China. In the process of rice processing, in order to ensure the quality of rice, broken rice needs to be removed, and a screener is needed to remove the broken rice.

[0003] The authorization announcement number is CN 216441087 U, a screener for processing organic rice, which relates to the technical field of organic rice processing. The utility model comprises a shell body, a coarse screen and a fine screen are slidably connected inside the shell body, two screen pushing mechanisms are installed at one end of the shell body, which are used to drive the coarse screen and the fine screen to move, a collecting box is slidably connected to the bottom end of the shell body, and a collecting box pushing mechanism is installed inside the shell body to drive the collecting box to move;

[0004] The above-mentioned document can push the screen by electric means through the setting of the rotating disk and the middle connecting rod, which saves manpower and completes the screening function.
