Abstract
Description
Technical Field
[0001] The utility model belongs to the field of seed selection equipment, in particular to a wind screen type corn seed selection device. Background Art
[0002] Corn seeds are generally screened before sowing. Screening can remove impurities, pests and diseases, stunted seeds, and mechanically damaged seeds, thereby improving the overall quality of the seeds. High-quality seeds mean higher germination rates, better growth potential, and stronger resistance to stress.
[0003] Through screening, we can ensure that the corn seeds sown have excellent genetic characteristics, which is beneficial to the uniformity, growth rate and yield of corn plants. At the same time, high-quality seeds also help improve the quality of corn, such as taste and nutritional value.
[0004] The selected high-quality seeds can reduce additional inputs such as replanting, weeding, pest and disease control caused by poor seed quality, thereby reducing production costs.
[0005] The size and shape of the seeds after screening are relatively consistent, which is conducive to mechanized sowing and improves sowing efficiency.
[0006] Therefore, designing a device that can automatically and conveniently select qualified corn seeds has high practical value. Utility Model Content
