DEVICE FOR SOIL COMPACTION Russian patent published in 2016 - IPC E02D3/74 

FIELD: construction.

SUBSTANCE: invention relates to the construction of soil compaction. It comprises a housing with a stove, an electric motor, on the shaft of which is rigidly fixed crank pivotally connected via a connecting rod to the driven crank shaft which is fixed imbalance. Links have a special arrangement of the transmission pivots: crossed from different angles α₁ and α₂ and spaced at the shortest distance l₁, l₂, and the associated value for $$\frac{l_1}{l_2}=\frac{\sin {\alpha }_1}{\sin {\alpha }_2}.$$

EFFECT: device provides controlled within wide limits inertial force which effectively compacts the soil and simultaneously moves forward or backward power device without involvement operatora.
