Research into Power and Load Parameters of Flexible Screw Conveyors for Transportation of Agricultural Materials

Abstract

In order to carry out experimental research and determine the performance criteria for the transportation of agricultural materials, a test unit of the combined screw conveyor has been designed by the authors. The axial speed and capacity of bulk material transportation on a curved route have been determined for the articulated-section operating device of the screw conveyor. The calculation has proved that the angular velocities of adjacent sections are almost the same. As a result of the research into the power and load parameters of flexible screw conveyors, graphic relations between the values of the torque T and power N, on the one hand, and the rate of rotation of the operating device’s drive shaft, on the other hand, have been plotted for the process of transportation of bulk materials in screw conveyors, when the process pipeline is fully filled with grain material.
