Embodiment 1

[0023] Such as figure 1 As shown, the frequency-tunable vibrating screen of this embodiment includes a vibrator, a suspension device, and a sieve plate 1 installed on the suspension device, the vibrator includes a drive motor 2, and the drive motor The cylinder installation frame 3 is connected through the reducer, and a group of striking hammers 4 with different phase angles are installed on the cylinder installation frame. When the motor drives the cylinder mounting frame to rotate through the reducer, the impact hammers of different phases continue to strike the force plate of the sieve plate, causing the sieve plate to vibrate. The frequency at which the hammer hits the vibrating screen changes, thereby realizing the function of frequency modulation.

[0024] In the frequency-adjustable vibrating screen described in this embodiment, the sieve plate is connected to the force plate 5, and the force plate is installed on one side of the vibrator. The force plate is set, whi...

Abstract

The invention provides a frequency-adjustable vibration screen. The frequency-adjustable vibration screen comprises a bearing trough arranged on an elastic system. One side of the bearing trough serves as an open end, and a vibration exciter is arranged on the other side, opposite to the open end, of the bearing trough. The frequency-adjustable vibration screen is characterized in that the vibration exciter comprises a drive motor, the drive motor is connected with a needle rod through a reducer, and the needle rod is connected with a connecting rod through a pin shaft; and the connecting rod is connected with a beating hammer, a sleeve is arranged on the beating hammer, and the sleeve penetrates a fixed guide rod. The frequency-adjustable vibration screen is simple in structure, more convenient to operate and maintain and low in equipment cost.

Description

[0001] Technical field: [0002] The invention relates to a frequency-adjustable vibrating screen, 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 on the...
