Description

Technical Field

[0001] The utility model relates to the field of vibrating screens, in particular to a vibrating screen transmission device. Background Art

[0002] The vibrating screen works by using the reciprocating vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyration vibration, while the lower rotating weight causes the screen surface to produce a conical gyration vibration. The combined effect causes the screen surface to produce a complex gyration vibration. Its vibration trajectory is a complex space curve. The curve is projected as a circle on the horizontal plane and an ellipse on the vertical plane. The amplitude can be changed by adjusting the exciting 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 screen surface motion trajectory and change the motion trajectory of the material on the screen surface.

Since the particle sizes of some raw materials are not uniform, some raw materials are easily stuck in the screen during screening, which in turn affects the screening of subsequent raw materials.
