Multi-dimensional corn kernel cleaning device with amplitude based on inertia adjustment

A throwing type short-range corn kernel cleaning device comprises a machine frame, an upper screen, a throwing crankshaft, a lower screen, a front driving crankshaft, a driving belt wheel, a transmission belt wheel, a transmission sliding way and a rear driving crankshaft. During operation, external power is transmitted in through the driving belt wheel, the front driving crankshaft and the rear driving crankshaft are driven to rotate, the lower screen is driven to do reciprocating motion, meanwhile, the front driving crankshaft and the throwing crankshaft drive the upper screen to do throwing motion through the transmission sliding way, and threshing of corn is achieved. The cleaning quality is good, and the device is suitable for large-feeding-quantity operation of a small corn kernel harvester.
