The paper is focused on the computer simulation and experimental testing of the improved vibratory screening conveyor equipped with the controllable crank-type exciter characterized by the changeable forced frequency and eccentricity. The main scientific novelty of this research is implementing the three-mass discrete-continuous oscillatory system, whose disturbing body is designed in the form of a flat spring characterized by both inertial and stiffness parameters. The proposed excitation method and the novel spring system design can be effectively used while developing new vibratory technological equipment in various industries, e.g., chemical, mining, pharmaceutical, agricultural, etc. The 3D-model of the vibratory screening conveyor is designed in the SolidWorks software; the strength analysis of the conveyor’s springs is performed using the finite-element method integrated into the SolidWorks Simulation application; the control system of the experimental prototype is developed using Arduino software and hardware; the experimental data is processed with the help of the Serial Port Plotter software. The main results of the theoretical research present the specific geometrical parameters of the conveyor’s flat springs ensuring its operation under energy-efficient near-resonance conditions and time dependencies. The results of experimental investigations allow for determining the dynamic response of the conveyor’s oscillatory system at different forced frequencies, which correspond to the eigenfrequencies of the disturbing spring and the intermediate springs. The obtained results allow for substantiating the optimal operating conditions of the vibratory screening conveyor.
