Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to a vibrating chute mechanism. Background Art

[0002] Existing vibrators are generally installed below the vibrating bowl, so that items vibrate in the vibrating bowl and then are discharged from the chute.
