Abstract

The invention provides an amplitude-adjustable vibration screen which comprises a vibration exciter, a hanging device and a screen plate mounted on the hanging device. The amplitude-adjustable vibration screen is characterized in that the vibration exciter comprises a movable mounting support, a driving motor is mounted on the movable mounting support, the driving motor is connected with a length-adjustable needle rod, and the needle rod is connected with a sleeve through a first pin shaft; and the end, penetrating the sleeve, of a swing rod is fixed through a second pin shaft mounted on the lower portion of the movable mounting support, and the other end of the swing rod is connected with a beating hammer. The amplitude of the vibration screen can be adjusted according to needs, the adjusting mode is simple and practical, and the application range is wide.

Description

[0001] Technical field: [0002] The invention relates to a vibrating screen with adjustable amplitude, which belongs to the technical field of industrial equipment. [0003] Background technique: [0004] The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material o...
