[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2As shown, the corn anti-blocking vibrating screen of this embodiment includes a bottom plate 1, a column 2, a screen 3, a screen hole 4, a spring 5, a vibration motor 6 and a feed plate 7, a through hole 8 is provided on the feed plate 7, a hydraulic cylinder 9 is fixedly installed above the bottom plate 1, a lifting plate 10 parallel to the feed plate 7 is fixedly installed at the top position of the hydraulic cylinder 9, and a push rod 11 adapted to the through hole 8 is provided on the lifting plate 10, and the push rod 11 can push the corn stuck in the screen hole 4 upward. The screen hole 4, the through hole 8 and the push rod 11 correspond one to one, and the diameter of the screen hole 4 is larger than the diameter of the through hole 8.

[0022] Furthermore, the upper end surface of the push rod 11 is located in the same plane as the upper end surface of the blanking plate 7 to prevent small grains of corn or impurities from entering or passing through the through hole 8.

[0023] Furthermore, the bottom of the sieve hole 4 is a trumpet-shaped structure, which facilitates the insertion of the top rod 11 from the bottom to clean the corn in the sieve hole 4.
