TILLAGE DEVICE Russian patent published in 2023 - IPC A01B21/08 

FIELD: agriculture.

SUBSTANCE: invention relates to tillage machines and implements that loosen the soil while simultaneously grinding plant residues. The tillage implement contains a frame with transverse beams, on which vertical posts are mounted with their upper sides rotatable, at the lower ends of which holders with working parts are installed, as well as a roller mounted using a leash on the frame. The working bodies are a pin drum and a spherical disk. The pin drum has a diameter D greater than the diameter d of the spherical disk, and the distance between the working bodies on one holder is less than half the diameter of the pin drum, but more than half the distance between the racks located on the same beam. The diameters d of the spherical disk and D of the pin drum are related by the ratio D = 1.2…1.3d, and the distance between rows of racks is 1.5 times greater than the distance between sections.

EFFECT: improving the quality of soil crumbling without changing energy intensity.
