1.1 Analysis of the structure of bucket elevator
Due to the special national conditions of our country, bucket elevator occupies the absolute majority. There are three types that are most widely used among the bucket elevator :TD type belt type, TH type ring chain type and plate chain type. There are many classifications of the bucket elevators, and there are different divisions for different classifications. According to the different type of the hoppers, thebucket elevators can be divided into shallow hopper, deep hopper, guide side hopper.In light of the unloading characteristics, the bucket elevators can be divided into centrifugal type, centrifugal - gravity type and gravity type. The centrifugal discharge is suitable for conveying powdery, granular and small block materials with good fluidity while gravity unloading for transporting lumpy and heavy materials. The bucket elevator is specially used for continuous conveyer equipment. For its features of small floor space , high lifting height and large throughput, it is widely used in fodder and grain processing plants. Bucket elevator is composed of driving device , traction parts , hopper , shell , bottom wheel , tensioning device , throwing mouth and other parts. The tensioning device, hopper and casing are the key design components. 1.2 Work process analysis
The operation principle of bucket elevator : the material is loaded into the hopper through the bottom of the elevator running with the elevator chain or belt to the top, past the head wheel and turning down where the hopper throws the material into the corresponding receiving device.The working procedure of bucket elevator can be simplified into three parts: loading , lifting and unloading.After the bucket elevator operates for a period of time and contacts with the lower part of the grain, during the bucket rotating it will dig part of the grain, and then lift vertically. When it reached the head part, it will be thrown out with the rotation of the belt, and be conveyed to the destination by the conveyor.
In the process of conveying reflux occurs to reduce the transporting efficiency and wear the bucket and eventually affect its service life,therefore we should ，in practice,try our best to reduce and overcome the occurrence of the reflux.
Therefore, we must study the unloading process of hopper. Through the analysis and simulation, we made the corresponding shape of the casing to determine the bucket model, the size of the head cover shell. The purpose is to reduce the loss of materials in the work of the elevator, transportation time and improve transportation efficiency.
