The invention disclose efficient multifunctional agricultural machinery. The structure of the machinery comprises a grain box, an agricultural machinery vehicle body, assisting wheels, a grain liftingdelivering device, a control delivering device,walking wheels, a cutting device, an illumination lamp, an operating chamber, an electricity storage box and a lifting device, two assisting wheels arearranged and welded to the two ends of the left side of the bottom of the agricultural machinery vehicle body respectively, and the grain lifting and delivering device is fixedly welded to the middleof the bottom of the agricultural machinery vehicle body and is in reinforced connection through bolts. A first gear is embedded in the upper portion of a rotary worm, the rotary worm is driven by thefirst gear to start rotating and drive a fourth gear to start rotating, the fourth gear meshes with a third gear while the fourth gear rotates to drive a first connecting rod and a second connectingrod to start rotating, an axial flow roller is welded to a cutter knife, the cutter knife is driven to operate when the axial flow roller rotates, the operation of equipment is time saving and labor saving, driving is conducted by adopting electricity, and the machinery is energy saving and environmentally friendly.
