[0002] To improve grass seed quality, seeds usually need to be screened. Seeds that are shriveled, deformed, or large or small are not conducive to cultivation and can easily lead to various problems during planting, such as low germination and survival rates, and poor drought and flood resistance. Therefore, only by screening seeds with moderate particle sizes for planting can crop planting efficiency be effectively guaranteed. In addition, seeds with moderate particle sizes are conducive to mechanized sowing. Natural grass seed storage cleaning devices are used to clean and screen grass seeds before storage to remove impurities and unqualified seeds.
