[0002] The utility model with authorization announcement number CN217069521U discloses a corn seed screening device. The particle size of dry-fried corn seeds is smaller than that of plump corn seeds. Therefore, the dry-fried corn seeds fall from the screening holes of the screening net while the plump corn seeds remain in the screening net, and the plump corn seeds gradually move to the first discharge port under the pushing action of the spiral blades. However, when this structure is in use, when it is used for a long time, the screening net will be blocked by small corn kernels, thereby resulting in a decrease in screening efficiency. The screening net is fixedly connected to the box, which makes it inconvenient to clean the small corn kernels. Utility Model Content
