Description

Technical Field

[0001] The utility model relates to the technical field of seed impurity removal, in particular to a device for removing impurities from crop seeds. Background Art

[0002] Seeds, the reproductive bodies unique to gymnosperms and angiosperms, are formed from ovules through pollination and fertilization. Seeds generally consist of three parts: the seed coat, embryo, and endosperm. Some mature seeds contain only the seed coat and embryo. Seed formation allows the young sporophyte ovule to be protected by the mother and receive adequate nutrients, similar to a mammalian fetus. Crop seeds require cleaning before planting.

[0003] Announcement No. (CN221413460U) discloses a mechanism for removing impurities from crop seeds. The seeds are placed into a processing box through a feed port. The seeds naturally descend in the processing box and gradually separate as they descend. The fan is started in advance and the falling seeds are blown at high speed by the fan. The lighter impurities in the seeds can be blown into a collection box by the blowing. Because the lighter impurities descend more slowly and the naturally descending seeds will not be blocked together, the lighter impurities can be effectively removed by blowing. The feed port in the above device is large, which will cause the feeding speed to be too fast, so that the impurities in the seeds cannot be fully removed, which needs to be improved.
