Technical Field

[0001] The utility model relates to the technical field of corn seed screening equipment, in particular to a screening machine for corn seed breeding. Background Art

[0002] Corn is an annual monoecious, cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop, and also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. In order to increase the survival rate of corn planting, fuller corn seed grains are generally selected for cultivation. When selecting corn seeds, screening equipment is usually used to screen a large amount of corn.
