A wheat seed selection device
This invention proposes a wheat seed selection device, including a frame. Inside the frame, from top to bottom, are inclined and adjustable primary and secondary screens. This invention features a reasonable design and convenient operation. By setting multiple inclined adsorption plates between the primary and secondary screens, it can adsorb metallic impurities mixed in with the wheat seeds. Because there are multiple adsorption plates, falling seeds first land on them, adsorbing metallic impurities without accumulation. Furthermore, it allows workers to easily remove the adsorbed metallic impurities from the drain outlet, achieving rapid cleaning. In addition, the pull-out primary and secondary screens facilitate maintenance and replacement, improving disassembly and assembly efficiency, and also allow for easy screen angle adjustment to meet screening needs under different working conditions, thus expanding its applicability.
