PLOUGH Russian patent published in 2008 - IPC A01B13/00 

FIELD: agriculture.

SUBSTANCE: plough consists of frames with coulters and mouldboards, draw bars, beams, shoes, knives, hitch, damping devices, chains. Each plough frame is fitted with additional coulter on the left. The additional coulter is sloped at an acute angle to the line of motion with the possibility to adjust coverage by rotating it around mounting hinge. Mouldboard upper parts with curvature radius of 180 mm are fixed to draw bars. Frames are connected to beams through the draw bars and lag hinges with the possibility of rotating in relation to the beams. Each beam is equipped with a shoe and vertical knife. Back parts of the shoes are connected to the knives by hinges, pushers and cranks to ensure automatic adjustment of knife penetration into the soil depending on pressure on the shoes with cutting angle alteration. Each beam is connected to hitch by flapping hinges and is placed at the distance of 0.04 - 0.1 m from the soil surface depending on ploughing depth. Adjustable damping devices are put between each beam and hitch. Angles of rotating beams down in relation to the hitch are limited by chains, and those of rotating up - by running of damping devices.

EFFECT: improvement of quality of soil ploughed with reducing energy consumption.
