大豆玉米带状复合种植同步精量排种器
By designing a screening mechanism and a synchronous precision seed metering device controlled by a motor, the problems of cumbersome operation and impurity blockage in existing seed metering devices have been solved. This has enabled flexible control of seed falling frequency and improved purity, thereby enhancing planting efficiency and equipment stability.
