Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a vibrating screen with a shock absorbing mechanism. Background Art

[0002] The vibrating screen works by utilizing the reciprocating vibration generated by excitation. The upper rotating weight of the vibrator produces planar gyratory vibration, while the lower rotating weight causes the screen surface to produce conical gyratory vibration. The combined effect causes the screen surface to produce compound gyratory vibration. Its vibration trajectory is a complex spatial curve, which is projected as a circle on the horizontal plane and an ellipse on the vertical plane. By adjusting the upper and lower rotating weights, the shape of the curve can be changed, and by adjusting the space of the upper and lower weights, the curve shape of the screen surface motion trajectory and the motion trajectory of the material on the screen surface can be changed.
