Abstract:
The bucket elevator with centrifugal discharge designed for transport of grains is analysed in the paper. Operation, main characteristics and major elements of bucket elevator are described in the paper. Essential elements of calculation of the drive mechanism are presented, bucket discharge type is adopted and main elements of transport device are selected. A rubber belt is selected as traction device. Available transport capacity ranged from 15 t/h to 45 t/h, while lifting height was 18 m. Based on initial data and calculations, a spatial 3D model of the elevator is formed. Static finite element analysis (FEA) of the elevator bucket was conducted based on previously formed model. A modified version of the bucket was made in order to show the influence of design change on mass, deformation and the stress states of the elevator buckets. Modelling of the elevator bucket was conducted using 3D Autodesk Inventor software.
