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

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machinery industry, in particular to tools for soil packing. The tools for soil packing comprises rollers mounted one behind the other on a frame on the axes. The rollers are made in the form of cylinders of equal diameter, mounted on axles which are arranged along the longitudinal axis of symmetry of the cylinders. On the lateral surfaces of both cylinders there are holes arranged in staggered order. On the axle ends protruding outwards of the cylinders on one side the sprockets of the same diameter are mounted, coupled with a chain. When rotating the rollers the projections of the holes in contact with the soil surface, of the second roller on the same soil region are located between the projections of holes of the first roller. The diameter of the holes does not exceed the size of the soil clods, maximum permissible by the agrotechnical requirements. Inside each cylinder, the leashes are pivotally mounted on the axles, and on the ends of the leashes the flat curved hammers are mounted, which are made as a circular arc in the longitudinal section and arranged concentrically to the lateral surface of the cylinders. The gap between the inner side surface of the cylinders and the outer surface of the hammers does not exceed the minimum permissible size of the soil clods.

EFFECT: in the use of the tool for soil packing the quality of soil packing and soil clods crumbling is improved.
