FIELD: civil engineering. SUBSTANCE: vibration sinker includes a case. Cam shafts integrated into individual groups are placed in the case. A group with hollow cam shafts is connected through a gear to drive cam shaft. Cam shafts of other group are also hollow, connected through a gear to the cam shaft and integrated in pairs to the cam shafts of the first group through an axle passing through their cavity. The axle is rigidly connected to the case. EFFECT: higher efficiency. 2 dwg
