WORKING TOOL OF THE CULTIVATION TOOL Russian patent published in 2018 - IPC A01B13/14 

FIELD: agriculture; mechanical engineering.

SUBSTANCE: invention refers to the field of agricultural engineering, in particular to the working tools for basic cultivation. Working tool of the cultivating tool includes the stand (1), the plough share (2), the blade (3), the ripper (4), which is attached to the side of the stand (1) and is adjustable in height. Chisel (5) of the ripper (4) is exposed below and in the middle of the plough share (2) in the transverse-vertical plane. Ripper (4) is attached to the stand (1) through the spacer (6), at which at least two rows of vertical holes (7) are provided. Holes (7) provide for two positions of the chisel (5) in the alignment, relative to the tip and the toe of the plough share (2). In case of the first position, the chisel groove depth (5) relative to the tip of the plough share (2) is not less than half the difference between the width of the plough share (2) and the chisel width (5). In case of the second position, when the chisel (5) is worn with respect to the toe of the share (2), the groove of the chisel (5) with respect to the toe tip (2) is not more than half of this difference.

EFFECT: such a design solution provides for the reduction in operating costs for basic cultivation.
