This video features a homemade vibrating grain screener. The screen mesh is suspended by ropes, and the screen frame is connected to a drive wooden rod linked to an electric tricycle. Powered by the tricycle, the screen shakes back and forth to separate grain.
The tricycle delivers power to drive the connecting rod for reciprocating push-pull movement. The suspended screen vibrates and sorts grain according to particle size. The drive wooden rod mounted on the suspended screen connects directly to the tricycle’s power outlet to transmit reciprocating driving force.
Ropes hoist the entire screen assembly. Power keeps it swinging steadily. Fine grain sifts through the mesh, while coarse impurities stay on the screen surface. Fine grain falls into the collection area underneath, and continuous feeding allows uninterrupted screening.
This device uses easy-to-source materials at low cost. It is assembled simply with ropes, screen mesh and wooden rods and driven by an electric tricycle, requiring no dedicated screening equipment. The suspended screening design creates little resistance for smooth feeding; grain rarely clogs the mesh, delivering consistent screening results.
