Abstract

A tool combination, including a share tip and an adjoining guide element, wherein the share tip and the guide element have threaded receptacles for fastening to a tine. An easy and secure fastening of both the share tip and the guide element is achieved according to this invention if the guide element has a threaded receptacle which is covered in the tool advancement direction by a cover portion of the share tip.

First claim

The invention claimed is:

1. A share tip ( 30 ) for an agricultural soil cultivating machine, comprising:
a base part ( 31 ) including a blade holder ( 37 ) at a first end and which has a blade ( 40 . 3 ), the base part ( 31 ) including a screw opening ( 33 ) for fastening to a support tine ( 10 ) of the agricultural soil cultivating machine; and
the base part ( 31 ) having a recess ( 38 ) at a second end opposite the first end, the recess covered in a tool advancement direction (V) by a covering section ( 38 . 1 ) and the recess disposed between the covering section and the support tine;
wherein a back surface of the base part is fastenable on the support tine, and the recess ( 38 ) is formed in the back surface open toward the back of the base part ( 31 ), and forms an insertion socket at the second end between the covering section and the support tine.

2. The share tip according to claim 1 , wherein the recess ( 38 ) has at least one locking piece ( 38 . 3 ) to provide a form-fitting locking of a guide element ( 50 ) perpendicular to the tool advancement direction.

3. The share tip according to claim 2 , wherein the recess has two locking pieces ( 38 . 3 ) spaced apart from each other and perpendicular to the tool advancement direction.

4. The share tip according to claim 2 , wherein near the covering section ( 38 . 1 ), two locking pieces ( 38 . 3 ) are formed onto the back side of the base part ( 31 ), and the locking pieces ( 38 . 3 ) form support surfaces.

5. The share tip according to claim 4 , wherein the recess ( 38 ) has a connecting section ( 38 . 4 ) which integrally connects the locking pieces ( 38 . 3 ) to each other.

6. The share tip according to claim 5 , wherein an insertion socket of the recess is laterally bordered by insertion bevels ( 38 . 2 ) spaced apart from each other.

7. The share tip according to claim 6 , wherein in front of the screw opening ( 33 ) in the tool advancement direction (V) is a projection ( 34 . 1 ) which protrudes up from a deflection surface ( 34 ).

8. The share tip according to claim 1 , wherein the recess ( 38 ) has at least one locking piece ( 38 . 3 ) to provide a form-fitting locking of a guide element ( 50 ) perpendicular to the tool advancement direction.

9. The share tip according to claim 1 , wherein an insertion socket of the recess is laterally bordered by insertion bevels ( 38 . 2 ) spaced apart from each other.

10. The share tip according to claim 1 , wherein in front of the screw opening ( 33 ) of the share tip in the tool advancement direction (V) is a projection ( 34 . 1 ) which protrudes up from a deflection surface ( 34 ).

11. The share tip according to claim 1 , wherein the back surface of the base part ( 31 ) comprises a slot ( 39 . 1 ) disposed between the recess and the blade holder, and adapted to receive the support tine.

12. A tool combination, comprising:
a share tip ( 30 ) and a guide element ( 50 ), the share tip ( 30 ) and the guide element ( 50 ) including screw openings ( 33 , 57 ) for fastening to a tine ( 10 )
the guide element ( 50 ) including one of the screw openings ( 57 ) covered in a tool advancement direction (V) by a covering section ( 38 . 1 ) of the share tip ( 30 ), wherein the covering section does not include any opening;
wherein near an end oriented toward the share tip ( 30 ), the guide element ( 50 ) has an insertion projection ( 51 ) laterally inserted into a recess ( 38 ) formed in the share tip and between the covering section and the tine.

13. The tool combination according to claim 12 , wherein one or more locking pieces ( 38 . 3 ) lock the share tip ( 30 ) and the guide element ( 50 ) to each other in a form-fitting fashion perpendicular to the tool advancement direction (V).

14. The tool combination according to claim 13 , wherein the covering section ( 38 . 1 ) is at an end of the share tip ( 30 ) opposite a blade holder ( 37 ) and the share tip ( 30 ) has a screw opening ( 33 ) through the share tip and positioned between the covering section ( 38 . 1 ) and the blade holder ( 37 ).

15. The tool combination according to claim 12 , wherein the insertion projection ( 51 ) has two guide bevels ( 54 ) arranged in a V shape relative to each other.

16. The tool combination according to claim 15 , wherein in the connecting region to the share tip ( 30 ), the guide element ( 50 ) has a hard material element ( 56 ), in particular an armored layer or the like.

17. A tool combination, comprising:
a share tip ( 30 ) and a guide element ( 50 ), the share tip ( 30 ) and the guide element ( 50 ) including screw openings ( 33 , 57 ) for fastening to a tine ( 10 )
the guide element ( 50 ) including one of the screw openings ( 57 ) covered in a tool advancement direction (V) by a covering section ( 38 . 1 ) of the share tip ( 30 ), wherein the covering section does not include any opening and covers a recess ( 38 );
wherein near an end oriented toward the share tip ( 30 ), the guide element ( 50 ) has an insertion projection ( 51 ) inserted into the recess ( 38 ) laterally.

18. The tool combination according to claim 12 , wherein in the connecting region to the share tip ( 30 ), the guide element ( 50 ) has a hard material element ( 56 ), in particular an armored layer or the like.

19. A tool combination for a tine of an agricultural soil cultivating machine, the tool combination comprising:
a share tip ( 30 ) including a blade holder ( 37 ) at a first end and a recess ( 38 ) at a second end opposite the first end, the recess covered in a tool advancement direction (V) by a covering section, the share tip ( 30 ) further including a first screw opening ( 33 ) disposed between the covering section and the blade holder, for fastening the share tip to the tine;
a guide element ( 50 ) including an insertion projection ( 51 ) insertable into the recess ( 38 ) and including a deflection surface extending from the insertion projection and beyond the recess ( 38 ), the guide element having a second screw opening ( 57 ) for fastening the guide element to the tine ( 10 ), wherein the second screw opening ( 57 ) is covered in the tool advancement direction (V) by the covering section ( 38 . 1 ) of the share tip ( 30 ) when the insertion projection is inserted in the recess ( 38 ).

20. The share tip according to claim 19 , wherein the covering section does not include any screw opening.
