AI Technical Summary
After prolonged use, existing seed screening devices are prone to accumulating impurities or becoming clogged, leading to a decrease in screening efficiency and accuracy. Furthermore, the traditional process of replacing and cleaning screens is cumbersome and laborious, making it difficult to meet the needs of efficient agricultural production.
A seed screening device with easy screen replacement was designed. By setting up screening components, the screen can be quickly rolled up and installed, simplifying the disassembly and installation process. The screen can be easily replaced by using a pull-up component and a motor-driven threaded transmission system.
It effectively improves the convenience of screen replacement and equipment maintenance efficiency, reduces labor intensity, and enhances the efficiency and ease of maintenance of the screening device.
