Elastic screen surface material layered experimental device

Abstract

The invention relates to the technical field of mechanical equipment, and in particular relates to an elastic screen surface material layered experimental device. The elastic screen surface material layered experimental device comprises a rack, a movable frame, a driving component and a crack connection rod component; the crank connection rod component comprises a revolving shaft, a connection rodand an eccentric wheel; the driving component is connected with the revolving shaft and drives the same, so that the revolving shaft rotates around the own axis with respect to the rack; the axis ofthe revolving shaft is parallel to the hinge joint axis of the movable frame; the eccentric wheel is sleeved on the revolving shaft; the eccentric wheel is connected with the movable frame via the connection rod; the distance between the center of the eccentric wheel and the axis of the revolving shaft is an eccentric distance that can be adjusted to change the relaxation rate of an elastic screensurface. The new experimental device is provided for effective research on the motion rule of the elastic screen surface, and layering, screen passage, bounce and layering rule of the material through changing the eccentric distance of the eccentric wheel. The experimental device is simple in structure, convenient to change the parameter and helpful to improve the experimental efficiency.

[0003] The movement characteristics of the elastic screen surface and the material stratification and separation mechanism are important factors affecting the movement of the material on the screen surface. Now, the research on the material stratification of the fixed screen surface has tended to be perfect, but the research on the material separation characteristics of the elastic screen surface is insufficient. , relevant experts have used the two-mass vibration theory and the theory of elastic material mechanics to design the elastic screen surface screening device - the relaxation screen, to study the material layering characteristics of the elastic screen surface during the relaxation movement, but most experts are studying the screening device. Surface motion characteristics and single particle motion characteristics, relatively few studies on complex particle groups
