COMBINED TILLAGE TOOL FOR BASIC TILLAGE OF SOLONETZ SOIL Russian patent published in 2005 - IPC

FIELD: agricultural engineering, in particular, equipment for basic cultivation of solonetz soil in closed furrow mode and for surface cultivation of soil by rotavation method.

SUBSTANCE: tillage tool has frame, share, tiered rotavation drums disposed behind share and equipped with knives, drive mechanism made in the form of reducer and adapted for driving of rotavation drums, and seeding unit. Lower part of reducer is deepened into soil together with rotavation drums, which are adapted for rotation in opposite directions. Rotavation drums are arranged in spaced relation with respect to one another, rotate at equal angular speeds and have unequal diameters, with total value of diameters exceeding thickness of soil layer under tillage process. Share is positioned in front of rotavation drums and is deepened to depth equal to half the thickness of soil layer under tillage process. Gas distributing device disposed immediately behind share is connected through filter with exhaust pipe of tractor engine. Ratio of rotavation drum diameters, distance between axes of rotation of rotavation drums and angular offset are set in accordance with respective dependence.

EFFECT: improved quality of basic tillage of solonetz soil.
