Abstract

A cultivator for an agricultural soil processing machine, which includes a base part which has a cutting element on a cutter support. The base part has at least one screw receiving area for securing to a support, in particular a tine of the agricultural soil processing machine. The screw receiving area is designed as a blind hole with an inner thread and is recessed into a cultivator support surface aligned opposite the tool advancing direction of the cultivator, or the screw receiving area is designed as a through-bore with an inner thread and is covered by at least one wear protection element in the tool advancing direction.

First claim

The invention claimed is:

1. A cultivator attached to an agricultural soil processing machine support portion, the cultivator comprising: a base part having at least an inner surface, an outer surface, a proximal end, a distal end and a first length between the proximal end and the distal end, a cutter support defined on the distal end of the base part, a cutting element connected to the cutter support, at least a first wear protection element having a second length less than the first length provided on the outer surface of the base part intermediate the proximal end and the distal end thereof, at least a second wear protection element having the second length defined on an outer surface of the cutting element spaced away from the at least the first wear protection element, and at least one screw receiving area defined in the base part, whereby the base part is attached to the agricultural processing machine support portion,
wherein the at least one screw receiving area includes an inner thread and is recessed into the inner surface of the base part along a direction toward the outer surface of the base part.

2. The cultivator as claimed in claim 1 , wherein a front face of the cultivator, which is aligned in the tool advancing direction, is at least partially covered by the at least one of the at least the first or the at least the second wear protection elements, wherein the at least one of the at least the first or the at least the second wear protection elements is guided as far as the cutting element and wherein the at least one of the at least the first or the at least the second wear protection elements is arranged as far as a region of the at least one screw receiving area.

3. The cultivator as claimed in claim 1 , wherein the at least one screw receiving area extends to a terminal end intermediate the inner surface of the base part and the outer surface of the base part, and at least one of is rounded at the terminal end or has rounded transitions between internal surfaces thereof.

4. The cultivator as claimed in claim 1 , wherein the inner thread of the at least one screw receiving area defines a self-locking screw connection with a screw.

5. The cultivator as claimed in claim 1 , wherein a thickness of the base part in a region of the at least one screw receiving area, measured in a direction of a longitudinal extent of the at least one screw receiving area, is between 5 mm and 120 mm.

6. The cultivator as claimed in claim 1 , wherein a spacing of the at least one screw receiving area upstream in a tool advancing direction relative to a cutter of the cutting element is between 10 mm and 350 mm.

7. The cultivator as claimed in claim 1 , wherein two screw receiving areas are provided in the base part and wherein a spacing between the screw receiving areas is between 20 mm and 500 mm.

8. The cultivator as claimed in claim 1 , wherein the at least one screw receiving area extends to the outer surface of the base part, and is at least partially covered on the outer surface of the base part by the at least the first wear protection element.

9. The cultivator as claimed in claim 1 , wherein the support portion is a tine of the agricultural soil processing machine.

10. The cultivator as claimed in claim 5 , wherein the thickness of the base part in the region of the at least one screw receiving area is between 9 mm and 35 mm.

11. The cultivator as claimed in claim 8 , wherein the at least one screw receiving area is completely covered by the at least the first wear protection element on the outer surface of the base part.

12. A tool system attachable to an agricultural soil processing machine, the tool system comprising: a cultivator and a mounting region, the cultivator comprising a base part having at least an inner surface, an outer surface, a proximal end, a distal end, and a first length between the proximal end and the distal end, a cutting element arranged on a cutter support provided at the distal end, first and second wear protection elements, the first wear protection element having a second length less than the first length and being provided on an outer surface of the base part intermediate the proximal end and the distal end, the second wear protection element having the second length and being provided on an outer surface of the cutter support, and at least one screw receiving area defined in the base part aligned with at least one corresponding mounting bore defined in the mounting region,
wherein the at least one screw receiving area includes an inner thread and is recessed into the inner surface of the base part extending along a direction toward the outer surface of the base part.

13. The tool system as claimed in claim 12 , wherein the at least one screw receiving area extends to a terminal end intermediate the inner surface of the base part and the outer surface of the base part.

14. The tool system as claimed in claim 12 , wherein the mounting region is a surface of a tine of the agricultural soil processing machine.

15. The tool system as claimed in claim 12 , wherein the at least one screw receiving area extends to the outer surface of the base part, and is at least partially covered on the outer surface of the base part by at least one of the first and second wear protection elements.

16. The tool system as claimed in claim 15 , wherein the at least one screw receiving area is completely covered by the at least one of the first and second wear protection elements on the outer surface of the base part.

17. The tool system according to claim 12 , further comprising at least a third wear protection element defined on an outer surface of the cutting element.
