SOIL COMPACTION TOOL Russian patent published in 2020 - IPC A01B29/02 A01B29/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to tools for soil compaction. Proposed tool comprises axles mounted on the frame one after another and provided with axles of rollers made in the form of hollow cylinders of the same diameter. On one side of rollers there are sprockets connected by chain. Sprocket of the front roller is rigidly installed on the base of the hollow cylinder, and the sprocket of the rear roller is rigidly installed on its axis, besides, the transfer number of sprockets of the front and rear rollers makes at least 1 to 2. Inside the hollow cylinders of the rear and front rollers on their axes imbalances are installed. Imbalances are made in the form of rods pivoted on axes of front and rear rollers, which can be fixed in a given position relative to roll axis. On rods there are weighting materials with their fixation in preset position relative to rods axis. On the other side of rear roller on its axis rigidly installed sprocket, connected by chain with sprocket, rigidly installed on axis of front roller.

EFFECT: this structural solution is aimed at improvement of soil compaction quality and crumbling of soil lumps.
