Abstract

The invention discloses an inertial vibrating screen mechanism and belongs to the field of vibration screening. The mechanism comprises a rack, a screen body, a motor, springs and a connection rod mechanism; the motor is a power source and drives the connection rod mechanism to move; the connection rod mechanism is a five-rod mechanism and comprises two cranks and two connection rods, wherein the first crank and the second crank are both connected with a rack rotating pair, the two ends of the first connection rod are connected with a first crank rotating pair and a second crank rotating pair correspondingly, one end of the second connection rod, the second crank and the first connection rod are jointly connected through a rotating pair, and the other end of the second connection rod is connected with a screen body rotating pair; the screen body comprises a screen frame, a screen net and supporting frames; the two ends of each supporting frame are connected with the screen frame and the springs through bolts; the screen body is pushed by a double-crank mechanism to make reciprocating translational motion; the other ends of the springs are fixedly connected with sliders on a guiding rail; the rack comprises a base, stand columns and a cross beam; the lower ends of the stand columns are fixedly connected with the base; the upper ends of the stand columns are fixedly connected with the cross beam; and by means of vibration of a machine, classification, desliming and separation according to mass or particle diameter on materials are achieved.

Description

technical field [0001] The invention relates to the technical field of screening materials, in particular to an inertia vibrating screen mechanism. Background technique [0002] Vibrating machinery can be divided into crank-connecting rod-type vibrating machinery, electromagnetic vibrating machinery and inertial vibrating machinery according to its driving form. The crank-connecting rod vibration machine is driven by the crank-connecting rod mechanism, and its amplitude is stable, but the working noise is large, the life is short, the inertial force of the vibrating body cannot be automatically balanced, and the failure rate of the mechanical transmission is high. The electromagnetic vibrating machine is driven by an electromagnetic exciter, and its operating frequency is determined by the frequency of the alternating current. Its frequency is not easy to adjust, and the gap between the armature and the iron core should not be too large, which limits the amplitude of the vib...

Problems solved by technology

[0003] Aiming at the deficiencies of the inertial reciprocating linear vibrating screen, the purpose of the present invention is to provide an inertial vibrating screen mechanism, which solves the problem that the belt of the original pulley-driven vibrating screen mechanism is easy to slip, and at the same time increases the property of the quick return characteristic. The control of the rod length of the mechanism makes the screen body do reciprocating motion with rapid return characteristics, thereby improving the working performance of the vibrating screen, and the structure of the mechanism is simple, the operation is stable, the noise is small, the screening efficiency is high, and the cost is relatively low
