TOOL FOR SOIL COMPACTION Russian patent published in 2017 - IPC A01B29/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The tool for soil compaction comprises rollers mounted in sequence on the frame. The rollers are made in the form of cylinders of the same diameter and are mounted on axles which are arranged along the longitudinal axis of symmetry of the cylinders. On side surfaces of both cylinders the holes are made in staggered order. On the axles the chain-connected sprockets of equal diameter are mounted on one side. The sprockets are mounted in such a way that the projections of the holes of the second roller on the same soil region are located between the projections of the holes of the first roller. The diameter of the holes does not exceed the soil clod size maximum permissible with agronomic requirements. On the axles within each cylinder the leashes are pivotally mounted. On the ends of the leashes the hammers are mounted.

EFFECT: invention provides improvement in quality of soil compaction and crumbling of soil clods.
