Description

Technical Field

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

[0002] A vibrating screen works by the reciprocating spiral vibration generated by the excitation of a vibrator. The upper rotating weight of the vibrator causes the screen surface to generate a planar gyratory vibration, while the lower rotating weight causes the screen surface to generate a conical rotary vibration. The combined effect is to make the screen surface generate a compound spiral vibration.

[0003] However, in the prior art, when the existing vibrating screen is driven by a motor, since the vibrating screen vibrates up and down, there will be a certain amplitude of up and down vibration. The transmission structure connected by a belt may fall off, resulting in the stop of the transmission. Not only does it require personnel to fix the belt on it again, but it also affects the screening efficiency of the vibrating screen. Summary of the Utility Model
