[0002] Seeds are reproductive bodies unique to gymnosperms and angiosperms, which are formed by ovules through pollination and fertilization. Seeds are generally composed of seed coat, embryo and endosperm. Some mature seeds of plants only have seed coat and embryo. The seeds in production include not only the botanical seeds mentioned above, but also the organs that plants can use for reproduction and artificial seeds. In today's agricultural planting, the seeds used are basically high-quality seeds that have been manually screened.

[0003] After searching, the utility model patent with patent number CN219817017U discloses "a seed screening device". This seed screening device rotates the worm to drive the screening net to rotate, and improves the screening efficiency by connecting a vibration motor under the screening net. When the user screens the seeds for the second time, the angle of the screening net can be adjusted by the auxiliary screening mechanism, which can increase the feeding speed, and the quality of the screened seeds can be guaranteed by the screening motor.

[0004] While the device adjusts the angle of the screening net to increase the seed feeding speed, seeds of poor quality are easily discharged together with seeds of good quality, resulting in poor screening effect and being very inconvenient to use.

[0005] Therefore, it is necessary to provide a rapid screening device that can improve screening efficiency to solve the above technical problems. Utility Model Content

[0030] The working principle of a fast screening device that can improve screening efficiency provided by the utility model is as follows:

[0031] The first step: when in use, the eccentric block 14 is driven to rotate by the first motor 13. The rotation of the eccentric block 14 drives the first motor 13 and the second top plate 12 to shake. The second top plate 12 can drive the two groups of first top plates 6 to shake through the connecting transverse plate 15 and the connecting vertical plate 9. The first top plate 6 drives the screen 3 to shake through the connecting rod 7. The shaking of the screen 3 can lift up the seeds.

[0033] Compared with the related art, the rapid screening device provided by the utility model can improve the screening efficiency and has the following beneficial effects:

[0034] The eccentric block 14 is driven to rotate by the first motor 13. The rotation of the eccentric block 14 drives the first motor 13 and the second top plate 12 to shake. The second top plate 12 can drive the two groups of first top plates 6 to shake by connecting the horizontal plate 15 and the vertical plate 9. The first top plate 6 drives the screen 3 to shake through the connecting rod 7. The shaking of the screen 3 can lift the seeds, thereby improving the seed screening effect. At the same time, due to the small inclination of the screen 3, the seeds roll down from the discharge port 2 slowly, the screening process is long, non-excellent seeds are easily screened out, and the screening effect is better. When the seeds fall from the variable diameter port 20 to the upper end of the rotating block 22, the seeds will enter the inside of the groove 23. The second motor 21 drives the rotating block 22 to rotate, which can drive the seeds inside the groove 23 to move. When the groove 23 rotates from top to bottom, the seeds will fall. The seed feeding speed can be controlled by this mechanism, which is very convenient to use.
