[0002] As people's living standards continue to improve, their requirements for crops are also increasing. Since the quality of seeds directly affects the harvest, seed selection is extremely important. The topic of superior seed screening devices is very meaningful. Such devices can help farmers select high-quality seeds more accurately, thereby improving agricultural yield and quality.
[0003] Existing screening devices remove impurities and substandard seeds of varying sizes from seeds through multi-stage screening or air separation. Multi-stage screening devices can screen seeds according to their size, ensuring that the screened seeds are of uniform size. Air separation devices can blow out light substandard seeds. However, conventional screening devices can only transfer seeds to different screening devices sequentially for alignment and screening, resulting in low screening efficiency during seed transfer and affecting the overall seed screening efficiency. Therefore, we propose an excellent seed screening device for crop cultivation. Utility Model Content
