WORKING BODY OF THE SUBSOILER Russian patent published in 2022 - IPC A01B13/08 A01B35/22 E02F9/28 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The working body of the subsoiler contains a curvilinear rack with a fairing with a paw attached to it. The fairing has a recess in the form of a groove for connection with a coaxial cutting sharp curved edge of the curved rack. The outer side of the fairing in the direction of movement is made of a sharp wedge-shaped shape and is connected to the stand by a fork ledge, one side of which rests against the rear edge of the cast lug, the other enters the groove of the cast lug located on the stand, above the curved sharp cutting curvilinear edge of the stand. The fairing with its sides, bending around the curvilinear rack, forms grooves on its sides, which are put on the cast tides of the curved rack. The sides of the fairing, superimposed on the curved post, open the rear bend of the curved post, along which marks the depth of immersion in the soil are applied. The lower part of the curved rack has a wedge-shaped shape, which is included in the reciprocal groove of the wedge-shaped paw. The walls of the groove of the wedge-shaped paw have a through hole coaxial to the through groove of the curved post, through which the curved post is connected to the wedge-shaped paw into the assembly by a pin. The surface of the wedge-shaped paw that acts on the soil consists of flat sections located at an acute angle in the direction of movement, symmetrical to the direction of movement. On the sides of the wedge-shaped paw, wings protrude, increasing the width of the grip. A recess is made on the lower part of the wedge-shaped paw.

EFFECT: reduced resistance to movement inside the cultivated soil.
