METHOD FOR BASIC TREATMENT, PREPARATION OF SEED BED, SOIL DECOMPACTION AND DEVICE THEREFOR (VERSIONS) Russian patent published in 2016 - IPC A01B61/04 A01B49/02 A01B35/22 A01B35/28 A01C5/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural engineering, in particular to methods for basic and surface soil treatment in pre-sowing period and devices for their implementation. Method includes preparing a seedbed and decompression of soil working elements (4) made in form of clutches and/or arched and/or chisel rippers and/or disks. Working members (4) are arranged on frame (1) and have an upper and lower part of rack and provided with lifting and lowering of working bodies (4) when meeting with obstacles or without raising and lowering. Upper and lower racks are interconnected and adapted to lock releasably. After separation of upper and lower portions of rack stroke of rack bottom element acts on stop element with its upper part lifting working member (4) above the ground and latching lower part in catcher of top part or frame (1).

EFFECT: engineering solution is aimed at improving reliability of implementation process and reliability of operation of working members of tillers.
