PLOUGHSHARE WEAR REDUCTION Russian patent published in 2022 - IPC A01B49/02 A01B35/18 A01B73/04 

FIELD: agriculture.

SUBSTANCE: tillage tool (10) with n working bodies (12), in particular paws, such as winged or pointed paws of a cultivator, is proposed. Working bodies (12) are arranged in one or more rows (16.1…16.3) following each other in working direction (A), perpendicular to working direction (A). Working bodies (12) have at least one first part (20) and second part (24). Tillage tool (10) has s disc tools (14), which are arranged in front of working bodies (12) in working direction (A) in one or more rows of discs (18.1, 18.2) following each other in working direction (A) and perpendicular to working direction (A). Each disc tool (14) is located at individual disc distance (ds) from central longitudinal axis (22) of tillage tool (10). First part (20) of each working body (12) is located at first individual body distance (dw1) from central longitudinal axis (22) of tillage tool (10), and second part (24) of each working body (12) is located at second individual body distance (dw2) from central longitudinal axis (22) of tillage tool (10), which differs from first individual body distance (dw1). Disc tools (14) and working bodies (12) are arranged in such a way that each first part (20) of the body with first lateral distance (dw1) includes disc tool (14) with lateral disc distance (ds) in such a way that first lateral working body distance (dw1) is equal to lateral disc tool distance (ds). Working bodies (12) have a ploughshare tip, which forms at least incomplete first part (20) of the working body. The number s of disc tools (14) is equal to the number n of working bodies (12), or working bodies (12) have one or two ends of wings (15.1, 15.2), which forms or form at least incomplete first part (20) of the working body. The number s of disk tools (14) is less than the number n of working bodies (12) by one, or the number s of disk tools (14) is more or less than double the number n of working bodies (12) by one. A method for the production of tillage tool (10) is also proposed, in which disc tools (14) and working bodies (12) are arranged in such a way that each first part (20) of the body with first lateral distance (dw1) includes disc tool (14) with lateral disc distance (ds) in such a way that first lateral working body distance (dw1) is equal to lateral disc tool distance (ds). Tillage tool (10) with working bodies (12), in particular paws, such as winged or pointed paws, and central longitudinal axis (22) is described. Tillage tool (10) has n working bodies (12), which are arranged in one or more rows (16.1…16.3) following each other in working direction (A), perpendicular to working direction (A), and s disc tools (14), which are arranged in front of working bodies (12) in working direction (A) in one or more rows of discs (18.1, 18.2) following each other in working direction (A) and perpendicular to working direction (A). Working bodies (12) have at least one first part (20) and second part (24). Disc tools (14) and working bodies (12) are arranged so that each first part (20) of the working body includes disc tool (14) located coaxially in working direction (A) in front of first part (20) of the working body. Working bodies (12) have a ploughshare tip, which forms at least incomplete first part (20) of the working body. The number s of disc tools (14) is equal to the number n of working bodies (12), or working bodies (12) have one or two ends of wings (15.1, 15.2), which forms or form at least incomplete first part (20) of the working body. The number s of disc tools (14) is less than the number n of working bodies (12) by one, or the number s of disc tools (14) is more or less than double the number n of working bodies (12) by one. A method for the production of tillage tool (10) is also described, in which disc tools (14) and working bodies (12) are arranged so that each first part (20) of the working body includes disc tool (14) located coaxially in working direction (A) in front of first part (20) of the working body.

EFFECT: more uniform wear of working bodies is provided in order to extend a service life of working bodies and reduce operating costs of a tillage tool.
