Abstract

The present invention relates to a tool system for an agricultural ground cultivating machine having a base part which communicates, by means of a releasable connection, with a carrier element, in particular with a tine of the agricultural ground cultivating machine, wherein the base part comprises a cutter and, adjoining the cutter, at least one hard material element, and wherein the carrier element comprises, in its end region pointing in the operating direction, laterally arranged wing shares which are fitted with hard metal plates. In this case, it is provided that the edge of the wing share which is fitted with hard metal plates runs up to a lateral surface of the carrier element. The present invention additionally relates to an associated wing coulter. The tool system has reduced wear and tear and consequently extended changing intervals.

First claim

The invention claimed is:

1. A tool system for an agricultural ground cultivating machine having a base part which communicates, by means of a releasable connection, with a carrier element of the agricultural ground cultivating machine, the base part comprises a cutter and, adjoining the cutter, at least one hard material element, and the carrier element comprises, in an end region thereof, pointing in the operating direction, laterally arranged wing shares which are fitted with hard metal plates,
wherein the base part covers at least in part one of a fastening plate of the wing shares or fastening elements of the wing shares for fastening the fastening plate on the carrier element transversely with respect to the operating direction, and
wherein edges of the wing shares fitted with hard metal plates run up to lateral surfaces of the carrier element.

2. The tool system as claimed in claim 1 , wherein a setting angle of the wing shares is adjustable in relation to the carrier element within a predetermined range and in that the at least one hard material element adjoining the cutter covers the hard metal plates, arranged in the region close to the carrier, of the wing shares transversely with respect to the operating direction at least in part in all the adjustable setting angles of the wing shares.

3. The tool system as claimed in claim 1 , wherein a distance between the edges of the wing shares, which is fitted with hard metal plates, and a ground area of the ground to be cultivated is smaller compared to a distance between an end point, located in the direction of flow of the ground material, of the at least one hard material element and the ground area.

4. The tool system as claimed in claim 1 , wherein the length of the at least one hard material element adjoining the cutter in the direction of flow of the ground material is adapted to a horizontal position of the wing shares which are fitted with hard material plates.

5. The tool system as claimed in claim 4 , wherein a projection of the at least one hard material element in the opposite direction to the operating direction into a plane which includes an edge comprising a greater length perpendicular to the operating direction than the extent of the hard material plates in said direction.

6. The tool system as claimed in claim 4 , wherein a projection of an outer dimension boundary of the at least one hard material element in the opposite direction to the operating direction into a plane which includes an edge comprising a greater length than the extent of the hard material plates into said direction.

7. The tool system as claimed in claim 1 , wherein the hard material element adjoining the cutter is realized in one piece or multiple pieces.

8. The tool system as claimed in claim 1 , wherein the hard material element is connected integrally to a cutting element which forms the cutter.

9. The tool system as claimed in claim 1 , wherein the distance from the hard metal plates, arranged in the region close to the carrier, of the wing shares to a plane which includes a lateral surface, facing the wing shares, of the carrier element, is smaller than the distance from an outer dimension boundary, which is transverse with respect to the operating direction, of the hard material element to the plane.

10. The tool system as claimed in claim 1 , wherein the cutter is realized in a stepped manner, wherein the central region of the cutter protrudes in relation to the outer region of the cutter.

11. The tool system as claimed in claim 1 , wherein joint edges which are realized between adjacent hard metal plates are aligned obliquely with respect to a surface which extends vertically with respect to the ground area and in the operating direction.

12. The tool system as claimed in claim 1 , wherein two wing shares which are arranged opposite one another on the carrier element are integrally connected together.

13. A tool system for an agricultural ground cultivating machine having a base part, wherein the base part communicates, by means of a releasable connection, with a carrier element of the agricultural ground cultivating machine, the base part comprises a cutter and, adjoining the cutter, at least one hard material element, and the carrier element comprises, in an end region thereof, pointing in the operating direction, laterally arranged wing shares which are fitted with hard metal plates,
wherein the base part covers at least in part one of a fastening plate of the wing shares or fastening elements of the wing shares for fastening the fastening plate on the carrier element transversely with respect to the operating direction, and
wherein the at least one hard material element which adjoins the cutter covers the hard metal plates, arranged in the region close to the carrier, of the wing shares transversely with respect to the operating direction at least in part.

14. A wing share for a tool system of an agricultural ground cultivating tool having a base plate, the wing share comprising a fastening plate configured to be fixed at an angle to the base plate, the base plate comprising hard metal plates which form an edge, wherein an edge of the wing share runs as far as into one of a region of the fastening plate or into a region of a transition contour which is formed between the fastening plate and the base plate, and
wherein the base part covers at least in part one of a fastening plate of the wing share or fastening elements of the wing share for fastening the fastening plate on a carrier element of an agricultural machine transversely with respect to the operating direction.

15. The wing share as claimed in claim 14 , wherein the fastening plate comprises mounting elements and/or mounting receiving means for fastening the wing share on the carrier element and the mounting elements and/or mounting receiving means are designed in such a manner that the wing share is connectable to the carrier element at different setting angles.
