VOLUME AMELIORATIVE RIPPER Russian patent published in 2013 - IPC A01B15/00 A01B13/10 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry, and in particular to ameliorative tillage tools for deep processing of heavy compacted soils without overturning. The volume ameliorative ripper is a spatial structure comprising two side inclined cutting racks of curvilinear parabolic configuration connected to each other by the plowshare in the lower part. In the upper part the side racks are connected by the "П"-shaped frame. The tool is made as welded construction. On the "П"-shaped frame an additional horizontal bar with teeth or an elastic plate is mounted, which support ends transfer the load by springs to the main frame. The springs mounted between the bar and the main frame provide a flexible suspension of the bar and contribute to reducing the dynamic loads on the working element. The position of the bar or elastic plate can be adjusted in height in the guides depending on the depth and the amount of lifting of the loosened soil. The horizontal bar mounting axis with teeth is fixed at the required depth with nuts. The spring stiffness is also adjusted with nuts. The teeth are fixed on the bar in a chessboard manner.

EFFECT: invention enables to reduce the resistance to loosening, to increase the uniformity of loosening along the whole profile of the loosened soil, and to reduce the soil cloddiness in the upper layer and levelling a soil surface.
