WORKING ORGAN OF SUBSOILER Russian patent published in 2019 - IPC A01B13/08 A01B35/22 E02F9/28 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the agricultural machine building. Working body of the subsoiler contains a curvilinear rack with holes for attaching to the tool frame and in the lower part with a flat asymmetrical multi-faceted arrow-shaped paw that has a wedge-shaped protrusion for the introduction of the stop ring. Arrow-shaped paw has a convex-shaped sole, formed by the release of a sinusoidal protrusion on the surface of a straight hollow cylinder, on which a fairing with a notch in the upper part presses the flat protrusion in the lower part and is fixed on the pointed frontal face of the rack with a holding clamp on it. Stop ring has a wedge stop of the lower part and a flat pad of the upper part. Upper part of the flat asymmetrical multi-faceted wedge is made in the form of a one-slit wedge, and the lower part of the curvilinear wedge, having a wedge-shaped ledge to accommodate the dihedral flat wedge, is provided with a through hole parallel to the wedge edge. Upper face of the placed dihedral flat wedge is parallel to the lower face of the wedge-shaped ledge of the curvilinear wedge and is connected to the lower face of the wedge-shaped ledge of the curvilinear wedge of the rack. Pin is inserted through the through hole of the dihedral flat wedge, the edges of which are held in the walls formed by a one-slit wedge-shaped groove in the one-slit wedge-shaped paw body, and the part of the pin between the paw walls has a cross-section smaller than its edges in the paw walls, freely entering the hole of the flat dihedral wedge.

EFFECT: improved design reliability is provided.
