Description

Technical Field

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

[0002] Wheat is a general term for plants of the genus Triticeum, which belongs to the "awned crops". The wheat fruit powder is white with small yellow-brown peel pieces. It is one of the staple foods of humans. After being ground into flour, it can be used to make bread, steamed buns, biscuits, noodles and other foods. Wheat has high genetic stability and can be directly kept for seeds. Conventional harvested wheat will have organic and inorganic impurities during the harvesting process. Most of the organic impurities are light objects such as roots, stems and leaves of various plants, while most of the inorganic impurities are various inorganic substances such as sand, stone and mud. Therefore, it is necessary to screen and remove impurities from wheat seeds through an impurity removal device. However, during the use of the current impurity removal devices, most of the devices cannot remove organic and inorganic impurities in wheat at the same time, so that the staff have to perform two screening and impurity removal operations on the wheat seeds, which is inconvenient to use. Therefore, we propose a screening and impurity removal device for wheat seeds to solve the above problems. Utility Model Content
