Abstract

The present disclosure provides a plow blade edge device for mounting to a moldboard of a plow comprising at least one adapter blade including a bottom edge having a carbide insert along at least a portion of the bottom edge. The device further includes at least one moldboard shoe selectively reversible to present the adapter blade at a first angle or a second angle. The device further includes at least one impact bar mounted to a front side of the adapter blade. The at least one moldboard shoe can include a bottom edge having a carbide insert along at least a portion of the bottom edge.

Claims

1. A plow blade edge system for mounting to a moldboard of a plow comprising:

a first plow blade edge segment and a second plow blade segment;

each plow blade segment including;

at least one adapter blade including a bottom edge having a carbide insert along at least a portion of said bottom edge;

at least one moldboard shoe selectively reversible to present said adapter blade at a first angle or a second angle wherein said at least one moldboard shoe includes a bottom edge having a carbide insert along at least a portion of said bottom edge,

at least one impact bar mounted to a front side of said adapter blade;

wherein said first plow blade edge segment is mounted adjacent said second plow blade edge segment wherein said at least one impact bar of said first plow blade segment is interlocked with said at least one impact bar of said second plow blade segment when attached to said moldboard.

2. The plow edge system as recited in claim 1, wherein each said at least one moldboard shoe is cast steel.

3. The plow edge system as recited in claim 1, wherein said plow edge system is mounted to a front plow moldboard including each said at least one moldboard shoe in said first angle.

4. The plow edge system as recited in claim 3, wherein said plow edge system is mounted to a wing plow moldboard including each said at least moldboard shoe in said second angle.

5. The plow edge system as recited in claim 1, wherein each said at least one moldboard shoe is welded to a back side of each said adapter blade.

6. The plow edge system as recited in claim 5, wherein each said at least one impact bar is welded to said front side of said at least one adapter blade.

7. The plow edge as recited in claim 5, further including at least two moldboard shoes welded to the back side of each said at least one adapter blade.

8. The plow edge as recited in claim 7, wherein each said impact bars include a wear line demarcating when the plow blade edge system needs replacing.

9. The plow edge as recited in claim 1, wherein interlocked said impact bars include an interlocking joint spanning across a merge line between said at least one adapter blade of the first plow blade segment and said at least one adapter blade of said second plow blade segment.

10. The plow edge as recited in claim 9, wherein said first angle is from about 55 degrees to about 75 degrees relative to the ground surface therebelow.

11. The plow edge as recited in claim 10, wherein said second angle is from about 70 degrees to about 90 degrees relative to the ground surface therebelow.

13. The plow edge system as recited in claim 1, wherein each said at least one moldboard shoe is cast steel.

14. The plow edge system as recited in claim 1, wherein said plow edge system is mounted to a front plow moldboard including each said at least one moldboard shoe in said first angle.

15. The plow edge system as recited in claim 3, wherein said plow edge system is mounted to a wing plow moldboard including each said at least moldboard shoe in said second angle.

16. The plow edge system as recited in claim 1, wherein each said at least one moldboard shoe is welded to a back side of each said adapter blade.

17. The plow edge system as recited in claim 5, wherein each said at least one impact bar is welded to said front side of said at least one adapter blade.

18. The plow edge as recited in claim 5, further including at least two moldboard shoes welded to the back side of each said at least one adapter blade.

19. The plow edge as recited in claim 7, wherein each said impact bars include a wear line demarcating when the plow blade edge system needs replacing.

20. The plow edge as recited in claim 9, wherein said first angle is from about 55 degrees to about 75 degrees relative to the ground surface therebelow.

21. The plow edge as recited in claim 10, wherein said second angle is from about 70 degrees to about 90 degrees relative to the ground surface therebelow.

12. A plow blade edge system for mounting to a moldboard of a plow comprising:

a first plow blade edge segment and a second plow blade segment;

each plow blade segment including;

at least one adapter blade including a bottom edge having a carbide insert along at least a portion of said bottom edge;

at least one moldboard shoe selectively reversible to present said adapter blade at a first angle or a second angle wherein said at least one moldboard shoe includes a bottom edge having a carbide insert along at least a portion of said bottom edge,

at least one impact bar mounted to a front side of said adapter blade;

wherein said first plow blade edge segment is mounted adjacent said second plow blade edge segment wherein said at least one impact bar of said first plow blade segment is interlocked with said at least one impact bar of said second plow blade segment when attached to said moldboard

wherein interlocked said impact bars include an interlocking joint spanning across a merge line between said at least one adapter blade of the first plow blade segment and said at least one adapter blade of said second plow blade segment.

22. An expendable plow blade wear system adapted for replaceable attachment to a plow moldboard, comprising:

at least one plow blade wear device, each at least one plow blade wear device integrally includes;

at least one adapter blade including a bottom edge having a carbide insert along at least a portion of said bottom edge;

at least two moldboard shoes selectively reversibly mounted to said at least one adapter blade to cant to the ground surface below at a first angle or a second angle relative to said at least one adapter blade;

at least one impact bar mounted to a front side of said adapter blade; and

,

said at least two moldboard shoes each including a bottom edge having a carbide insert along at least a portion of said bottom edge.

23. The plow blade wear device as recited in claim 22, wherein said at least two moldboard shoes are cast steel.

24. The plow blade wear device as recited in claim 22, wherein said first angle is from about 55 degrees to about 75 degrees relative to the ground surface therebelow.
