Studying of movement kinematics of dynamically active sieve

Abstract

The article presents the movement kinematics of the modular bar element of a dynamically active polymer sieve of a vibrating screen. On the basis of analytical methods, the mathematical model was obtained, which makes it possible to determine the law and trajectory of the modular bar element movement depending on its geometric characteristics, physico-mechanical properties of the polymer material, the regime and technological parameters of the vibrating screen. The results of this research show that in the working frequency range of the vibrating screen grate, modular bar element of the dynamically active sieve moves along the trajectories, the envelope of which is represented by Cassini’s ovals, which along with the generation of the amplitude component in the horizontal and vertical directions allows one to obtain the selfcleaning effect of the sowing surface.

“…The box vibrations are transmitted by two kinematically unbound iner tial vibration generators 4 operating in selfsynchronization mode. Given research [14], the sie ving surface is formed by a freely supported plate with round holes, which performs periodic shock-pulse oscillations in the vertical plane limited by support 5. To prevent the longitudinal movement of the sieving surface it is fixed by stoppers 6 [15].…”
