Description

[0001] The utility model relates to the technical field of seed screening, in particular to a drum type seed grading and seed mixing device. Background Art

[0002] Seeds are the basis of plant growth and development. Seed size is closely related to seed germination, emergence, growth rate, seedling size, etc., and also affects the seed yield of the plant. It is particularly important to carry out seed size grading to give full play to the potential of excellent varieties and meet the field production requirements of uniform, even and strong seedlings.
