SOIL CULTIVATING MACHINE, IN PARTICULAR, HOEING PLOUGH Russian patent published in 2011 - IPC A01B49/02 

FIELD: agriculture.

SUBSTANCE: machine comprises at least one frame with tilling implements, made of at least two serial front and rear sections of disks. Sections of disks are arranged across the longitudinal axis of the frame along with its motion. Each section comprises separately installed disks or a group of disks, as a rule, from two to five discs. Discs or groups of discs are independent and swinging relative to the frame with the possibility of deviation when impacted by the specified, preferably controlled, pressure and treatment of soil with discs with their continuous deepening. Discs of each section have angles of incline and attack (α1, α2), which are not equal to zero. Soil treatment is carried out by deepening of at least one support element, such as a wheel, a skid or a roller connected to the frame. Discs of at least one section have a diameter that differs from the discs diameter of at least one other section of discs. Discs of section or sections having large diameter have an angle (α1) of attack, which is less than the angle of attack (α2) in discs of smaller diameter in the section or sections.

EFFECT: invention provides for treatment of a soil layer of optimal thickness, which helps to improve growth of plants with reduction of power inputs.
