VIBRATING RAMMER FOR COMPACTION OF ROAD CONSTRUCTION MATERIALS Russian patent published in 2014 - IPC E02D3/46 E01C19/38 

FIELD: process engineering.

SUBSTANCE: invention relates to construction equipment, particularly, to vibrating rammers. Vibrating rammer comprises board with platform to support the drive articulated with vibrator arranged at said board. Said platform is mounted on rolling bearings and is coupled with the board via hinged with horizontal pin. The latter is located opposite the vibrator, at the end of board with rounded working surface circumscribed by radius with centre located at hinge pin. Articulation between vibrator and drive is composed by two-step belt drive with idle pulleys aligned with horizontal hinge. Vibrator and hinge are mounted at the board, at its opposite sides relative to the centre of gravity, at spacing defined by mathematical formula. Pin joint between said platform and said board rules out transfer of vertical oscillations to platform supporting the drive, hence to motor and operator handle.

EFFECT: better compaction.
