ROLLER FOR INTRA-SOIL COMPACTION Russian patent published in 2021 - IPC A01B29/04 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agriculture. The roller for intra-soil compaction contains sparsely spaced and assembled from pairs of opposite curved cup-shaped plates, rings-seals of the conical shape of the rim, fastened with spacer pipes in the battery and fixed to three-sided protrusions along the edges of a solid axis resting on bearing nodes from inside the pipe. A through hole in the shape of a deltoid is made on the flat base of the curved cup-shaped plates in the center of the circle. The edges of the base are raised and curved outwards parallel to the base with the formation of a circular flat surface on the periphery, radially projecting outwards with a sharp edge. The curved cup-shaped plates are closed in pairs by round-shaped surfaces into hollow sealing rings with a sharp protrusion and have a spacer disk fixed inside with a convex rim shape and flat ends. The through hole in the form of a deltoid of the spacer disk and the hole of the hollow sealing rings are offset coaxially. Spacer disks are attached by screws through the through holes along the concentric circles of hollow sealing rings, forming rollers for sealing with hollow sealing rings. The rollers for compaction are assembled through the through holes on the concentric circles of the rollers for compaction with long spacer pipes into a battery, which is fixed with short spacer pipes on bearing disks of a triangular convex-concave rim shape, which are placed at opposite ends of a solid axis that transmits the load through self-aligning bearing supports to the pipe. The bearing disks are located with a gap to the pipe.

EFFECT: invention makes it possible to increase the intra-soil compaction of the previously loosened soil.
