SECTION OF INTERMITTENT PLOWING Russian patent published in 2019 - IPC A01B35/18 A01B13/16 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building. Section of discontinuous cutting comprises frame and furrow-forming spherical discs installed on rotary posts fixed on the frame. Boron-forming spherical discs are installed symmetrically relative to longitudinal axis of section. Spring-loaded levers with sealing skis are arranged behind said disks. Leash is installed on the rack, and the ski is on a leash with the possibility of their rotation relative to the vertical axis. Pivotally connected to the pivoting posts are screw links of adjustment mechanism of attack angle of furrow-forming spherical disks. Screw mechanism is arranged between furrow-forming spherical discs to set their angle of attack from 24° up to 44° and is made in the form of turnbuckle with coupling and screws with opposite left and right thread fixed on rods. Coupling is installed on slider movable along longitudinal axis of section and arranged in guide on transverse beam of frame.

EFFECT: providing stability of movement across slopes of the tool with furrow-forming discs and increasing capacity and time of effective functioning of water-retaining intermittent furrows.
