Technical Field

[0001] This utility model relates to the field of agricultural seed screening technology, specifically to a seed screening device. Background Technology

[0002] Crop farming is a major component of agriculture. Its characteristics are: using land as the basic means of production, and utilizing the biological functions of crops to convert solar energy into chemical potential energy and agricultural products.

[0003] Seeds need to be screened before sowing to ensure germination rate and emergence rate, thereby increasing crop yield. Selecting high-quality seeds also ensures full and strong seedlings.

[0004] Before sowing, agricultural seeds need to be screened using screening equipment to prevent the presence of stones or other large particles in the seed pile, which could affect subsequent mechanical sowing. However, some current seed screening devices can only screen for larger particles such as stones and soil, and cannot screen out smaller particles such as dust and unfilled particles, thus limiting their effectiveness.
