Claims

[Scope of utility model registration request]

In a vibration compaction machine that has two vibrating drive shafts and two vibrating driven shafts attached with eccentric weights installed side by side, and rotates both shafts to cause vibration and compact the roadbed, etc., it is operated on the fixed side. An arm that rotates by a member is provided, and a gear that meshes with a gear of an excitation drive shaft is provided on a shaft rotatably supported on the arm, and an idle sprocket is connected to a sprocket of the excitation driven shaft, or A sprocket is provided that is directly linked by a winding member, and the phase of the eccentric weight can be arbitrarily changed by rotating the arm about the vibration driving shaft by the operating member. Vibration generation mechanism of vibratory compaction machine.
