Conical trajectory vibrating screen

Abstract

The invention discloses a conical trajectory vibrating screen, and belongs to the field of vibrating screening machines. Vibrating strength of a screening machine is matched with distribution of materials on a screen face. The vibrating screen is mainly composed of a screen box, the screen face, vibrators, a vibrating reduction supporting device and a base. The vibrators are mounted on the feeding end of the screen box, and the feeding end of the screen box is connected with the base through the vibrating reduction supporting device; the discharging end of the screen box is hinged to a spherical support fixed to the base through an elastic rod or connecting rod; the length of the elastic rod is smaller than the length of the screen box; and the vibrators are single-shaft vibrators, and the center line of a vibration shaft of each single-shaft vibrator passes through the center of the spherical support located on the base. The spherical support is in sliding connection or rolling connection with the elastic rod. According to the vibrating screen, the damage force of the resonance phenomenon to a screening machine during starting or closing down is greatly reduced; and the vibrating screen has the beneficial effects of being reasonable in structure, stable in work and high in screening efficiency, saving raw materials and energy and the like and is suitable for screening work of various materials.

Description

technical field [0001] The invention belongs to the field of vibrating screening machinery, and mainly relates to a conical track vibrating screen with spherical hinges and elastic rod constraints. Background technique [0002] In the prior art of vibrating screen application, there are mainly three types of motion trajectories: linear motion trajectory, circular motion trajectory and elliptical motion trajectory. In order to ensure the smooth and normal operation of the vibrating screen, it is necessary to pass the resultant force line of the vibrator through the center of gravity of the screen box, otherwise the vibration of the screen machine will be unbalanced, which will affect the normal operation of the screen machine. Since the resultant line of action of the vibrator passes through the center of gravity of the screen box, the movement track and vibration intensity of each part on the screen box are the same. Because the material on the screen surface at the feed en...

AI Technical Summary

Problems solved by technology

The design of the vibrator should meet the requirement of the maximum thickness of the material layer at the feed end of the screen box, so when the thickness of the material layer at the discharge end is small, the vibration intensity is excessive
