Description

Technical Field

[0001] The utility model relates to the technical field of seed cleaning, in particular to a seed cleaning machine with a screening mechanism. Background Art

[0002] Seeds are structures that grow from the ovules of seed plants after fertilization. They are generally composed of seed coat, embryo and endosperm. The embryo is the most important part of the seed and grows into a new individual after germination. The endosperm contains nutrients. Seeds are reproductive bodies unique to gymnosperms and angiosperms, formed by ovules through pollination and fertilization.

[0003] After searching, application number CN202120415569.X discloses a seed cleaning and processing equipment. This scheme can drive the third rotating rod to rotate around the discharge pipe in the inner cavity of the cleaning box and the third rotating rod to rotate by itself by setting a cleaning device, so as to facilitate the brush rod to clean the seeds in the inner cavity of the cleaning box. By setting a filtering device, larger stones or leaves are filtered out and enter the lower side of the inner cavity of the cleaning box. By setting a first motor, a spring, a first rotating rod and an elastic bar, the filter plate can be driven to move up and down to prevent slow seed filtering and increase the seed filtering speed.
