Crabsidling articulated mechanism for small tandem vibratory rollers

The utility model relates to a crabsidling articulated mechanism for small tandem vibratory rollers. A front articulated frame is articulated with a middle articulated frame through a steering shaft, a front stop block is welded on the vertical plate of the front articulated frame, the middle articulated frame is articulated with a rear articulated frame through a crabsidling steering shaft, and a rear stop block is welded on the vertical plate of the rear articulated frame. When a vehicle carries out edgewise rolling operation, the middle articulated frame is rotated relative to the rear articulated frame, the front articulated frame is rotated relative to the middle articulated frame as well at the same time, consequently, the vehicle crabsidles, that is, the front articulated frame and the rear articulated frame are parallel with each other, and are staggered from each other for a certain distance, and thereby the utility model can decrease the labor intensity of a driver during rolling operation, enhance
