[0002] A grain elevator, also known as a grain lift, is a specialized device used for storing, conveying, and lifting bulk materials such as grain and cereals. It primarily consists of a motor, reducer, drive sprocket, chain, guide pulley, and movable lifting components. It also includes a conveying mechanism, tensioning mechanism, guide mechanism, and protective devices. It is a mechatronic device. The working principle of a grain elevator is that the motor drives the reducer, which drives or raises the conveying mechanism, achieving the function of conveying or lifting grain. Specifically, grain is placed in a silo, where the guide pulley drives the chain to rotate, lifting the grain to a higher level.
