Abstract

A closing tool to be attached to a plough frame to engage a soil layer, the tool includes an attachment stem via which the closing tool is attached to the plough frame. Secured to the lower portion of the stem are wear resistant members.

Claims

1. A plough tool including;

a mounting stem via which the tool is supported so as to have an upper portion and a lower portion, the upper portion being provided so that the tool is supported by a plough frame and is moved in a forward direction thereby;

a flange fixed to the lower portion and extending downwardly and rearwardly therefrom so as to provide a lower surface inclined to the horizontal by an acute angle, said surface being generally planar; and

a wear resistant member fixed to said surface so as to cover a substantial portion of said surface, said wear member having a convex downwardly facing surface that is to engage the soil when the tool is moved in said direction.

2. The tool of claim 1, wherein said member is formed of a material that is harder than material from which said stem and flange are formed.

3. The tool of claim 1, therein said stem and flange are integrally formed.

4. The tool of claim 1, wherein said stem has a longitudinal axis and said surface is inclined to said longitudinal axis by a forward facing angle of between 60°

and 66°

.

5. The tool of claim 1, wherein when said stem is attached to a plougher frame for movement through a soil layer, said surface is inclined to the horizontal by an angle within the range of 20′

to 35°

.

6. The tool of claim 1, therein said wear resistant member is formed of tungsten.

7. The tool of claim 1, wherein said tool includes a fixing layer located between said surface and said wear member securing the wear member to said surface.

8. The tool of claims 1, wherein said layer is formed of solder.

9. The tool of claim 1, wherein the tool is a closing tool.

17. The tool of claim 3, wherein said stem has a longitudinal axis and said surface is inclined to said longitudinal axis by a forward facing angle of between 60°

and 66°

.

18. The tool of claim 17, wherein said wear resistant member is formed of tungsten.

19. The tool of claim 18, wherein said layer is formed of solder.

20. The tool of claim 19, wherein the tool is a closing tool.

10. A plough tool including:

a mounting stem via which the tool is supported so as to have an upper portion and a lower portion, the upper portion being provided so that the tool is supported by, a plough frame and is moved in a forward direction thereby;

a flange extending downwardly and rearwardly from the lower portion so as to provide a lower surface inclined to the horizontal by an acute angle, said stem and said flange being integrally formed, and said surface being generally planar; and

a wear resistant member fixed to said surface so as to cover a substantial portion of said surface, said wear member having a convex downwardly facing surface that is to engage the soil when the tool is moved in said direction.

11. The tool of claim 10, wherein said stem has a longitudinal axis and said surface is inclined to said longitudinal axis by a forward facing angle of between 60°

and 66°

.

12. The tool of claim 11, wherein when said stem is attached to a plougher frame for movement through a soil layer, said surface is inclined to the horizontal by an angle within the range 20°

60 to 35°

.

13. The tool of claim 12, wherein said wear resistant member is formed of tungsten.

14. The tool of claim 13, wherein said tool includes a fixing layer located between said surface and said wear member securing the wear member to said surface.

15. The tool of claim 14, wherein said layer is formed of solder.

16. The tool of claim 15, wherein the tool is a closing tool.
