Vibrating screen provided with adjustable vibration exciter

Abstract

The invention discloses a vibrating screen provided with an adjustable vibration exciter. The vibrating screen comprises a base and a sieve box, wherein the sieve box is positioned above the base; the base is connected with fixed devices through support columns; springs are arranged on the outer sides of the support columns and are connected with the base and the fixed devices; the fixed devices are fixedly connected with the sieve box; an oblique screen mesh and a screen mesh support rack are arranged in the sieve box; the sieve box is connected with the vibration exciter through a high-strength bolt; the vibration exciter comprises a fixed wheel and an adjustable flywheel and is connected with an electromotor through a belt; and the electromotor is connected with the base. According to the vibrating screen provided with the adjustable vibration exciter, center of gravity of the vibration exciter is changed through changing the position of the adjustable flywheel, the rotational inertia generated when the vibration exciter rotates changes, and the vibrating effect of the vibration exciter is changed to widen the working range of the vibrating screen, improve the adaptation of the vibrating screen and enable the vibrating screen to be more efficient, so that the problem in the prior art that the vibrating screen sorts minerals through same vibration only is effectively solved.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a vibrating screen with an adjustable exciter. Background technique [0002] As a kind of mineral processing machinery, the vibrating screen works by using the reciprocating spiral vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator makes the screen surface produce plane circular vibration, while the lower rotating weight makes the screen surface produce cone vibration. Surface rotary vibration, the combined effect of which causes the screen surface to produce double-rotating vibration. The vibrating screen uses an eccentric exciter as the excitation source, a spring as the elastic element, and a screen box as the movable part of the screening equipment; The material is thrown continuously along the circular direction on the horizontal screen surface, and moves forward while throwing up loose layers, completing the process of p...
