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

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building, in particular, to tools for soil compaction. Soil compaction tool includes rollers fitted on the frame one after another and provided with axes of rollers made in the form of hollow cylinders of the same diameter. On one side of rollers there is a variator consisting of pulleys and belt transmission. Pulley of front roller is rigidly installed on the basis of hollow cylinder, and pulley of rear roller is rigidly installed on its axis. On the other side of the rollers there is also a variator, wherein belt connected pulleys of front and rear rollers of variator are rigidly installed on their axes. Inside the hollow cylinders of the front and rear rollers on their axes imbalances are installed. Unbalances 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 weights there are weighting materials with their fixation in preset position relative to rods axis.

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