Abstract

A mounting assembly for plough skimmers comprises a mounting rail adapted to be connected to the main frame of a plough and a skimmer support bracket adapted to surround parts of the mounting rail. The mounting rail and the skimmer support bracket are arranged such that the mounting rail and the skimmer support bracket are braced against each other in at least two directions when the plough skimmer is in use, wherein the at least two directions are oblique to a ploughing direction.

First claim

The invention claimed is:

1. A mounting assembly for a plough skimmer, the mounting assembly comprising:
a mounting rail for connecting to a main frame of a plough;
a skimmer support bracket for connecting a plough skimmer to the mounting rail, such that the skimmer support bracket surround parts of the mounting rail,
wherein the mounting rail and the skimmer support bracket have aligned mating surfaces that are arranged obliquely to a ploughing direction such that the mounting rail and the skimmer support bracket are braced against each other in at least two directions when the plough skimmer is in use;
wherein the mounting rail and the skimmer support bracket are arranged such that the skimmer support bracket configured to be fixed to the mounting rail at a plurality of locations along the length of the mounting rail.

2. The mounting assembly of claim 1 , wherein the at least two directions are perpendicular to each other.

3. The mounting assembly of claim 1 , wherein the at least two directions are oblique to the ploughing direction.

4. The mounting assembly of claim 3 , wherein the mating surfaces are arranged at an angle of 10 degrees to 80 degrees, preferably at an angle of 30 degrees to 60 degrees, with respect to the ploughing direction.

5. The mounting assembly of claim 3 , wherein a first mating surface of the mounting rail is a bevelled edge.

6. The mounting assembly of claim 1 , wherein the mounting rail has a polygonal cross-section.

7. The mounting assembly of claim 1 , wherein an outer surface contour of the mounting rail matches an inner surface contour of the skimmer support bracket.

8. The mounting assembly of claim 1 , wherein the skimmer support bracket is a two-piece structure.

9. The mounting assembly of claim 8 , wherein the skimmer support bracket comprises a first part for connection with a first side of the mounting rail and a second part for connection with an opposite, second side of the mounting rail.

10. The mounting assembly of claim 9 , the first part of the skimmer support bracket comprises a first mating surface arranged on an inner surface of the skimmer support bracket, the first mating surface being shaped to mate with a first mating surface of the mounting rail, when the skimmer support bracket is connected to the mounting rail.

11. The mounting assembly of claim 9 , wherein the first and second parts of the mounting rail are permanently connected to each other.

12. The mounting assembly of claim 9 , wherein the first part has a generally U-shaped cross-section and/or wherein the second part is plate shaped.

13. Method for manufacturing a mounting assembly for a plough skimmer, comprising:
providing a mounting rail for connecting to the main frame of a plough;
providing a skimmer support bracket for connecting a plough skimmer to the mounting rail, wherein the mounting rail and the skimmer support bracket are arranged such that the skimmer support bracket configured to be fixed to the mounting rail at a plurality of locations along the length of the mounting rail, the skimmer support bracket being a two-piece structure comprising a first part and a second part;
arranging the first part of the skimmer support bracket on a first side of the mounting rail,
arranging the second part of the skimmer on an opposite, second side of the mounting rail;
connecting the first part and the second part of the skimmer support bracket with each other.

14. The mounting assembly of claim 11 , wherein the first and second parts of the mounting rail are welded to each other.

15. The mounting assembly of claim 12 , wherein the second part is L-shaped.
