Description

Technical Field

[0001] This invention relates to the field of seed screening technology, and more specifically, to an agricultural seed screening and classification device and method. Background Technology

[0002] Agricultural seeds refer to any plant organs that can be directly used for sowing in agricultural production. To distinguish them from seeds in botany, they are called agricultural seeds. Before planting, seeds need to be screened. A search revealed an agricultural seed screening device with application number CN202220168937.X, comprising a base plate. Its features include: a placement groove fixedly connected to the upper side of the base plate; one end of a support rod fixedly connected to the upper side of the base plate; the other end of the support rod fixedly connected to the long plate of an L-shaped plate; the short plate of the L-shaped plate fixedly connected to one end of a grooved plate; a motor bracket fixedly connected to one side of the grooved plate; a motor fixedly connected to the upper side of the motor bracket; the output shaft of the motor passing through the grooved plate; the end of the motor's output shaft fixedly connected to the center of one side of a turntable; and a screening mechanism movably connected to the eccentric part of the other side of the turntable. This patent application uses a sieving method to screen seeds and pebbles, but some unripe seeds are still mixed in, indicating that the screening is not perfect.

[0003] Seed flotation utilizes the difference in specific gravity between protein and starch in seeds. After soaking in water, the protein in the seeds absorbs five times more water than the starch. This reduces the specific gravity of high-protein seeds. Finally, solution flotation is used to remove the high-protein seeds. Specifically, the seeds at the bottom often clump together, pressing down the seeds that should float. Usually, the seeds are manually lifted repeatedly by inserting both hands, bringing the pressed seeds to the surface. The floating seeds also often clump together, keeping the seeds that should sink to the bottom together and floating on the surface. They are usually broken up by crushing or other methods.

[0004] Using bionic principles to design mechanical mechanisms to achieve manual lifting and crushing is a very good solution. Therefore, a seed screening device was designed that can simulate the human hand to pick up, stir and crush seeds. Summary of the Invention
