Abstract

A trench cleaning apparatus for attachment to a tractor, the trench cleaning apparatus for extricating crumbs from a trench into control of the tractor. The trench cleaning apparatus utilizes a rigid member having a top edge, a bottom edge, a first side edge and a second side edge. When the rigid member is inserted into a trench at an angle to horizontal and propelled, the first edge and the second edge engage the sidewalls of the trench and the bottom edge of the rigid member engages the bottom of the trench. As the rigid member is propelled, crumbs flow from the bottom of the trench to the top of said rigid member such that crumbs are extricated from the trench and the trench is cleaned. A bucket can be utilized in cooperation with the trench cleaning apparatus such that crumbs above ground level can also be removed.

Claims

1. A trench cleaning apparatus for extricating crumbs from a trench, the trench cleaning apparatus comprising:

a rigid member having a top edge, a bottom edge, a first side edge and a second side edge;

means for removably attaching said rigid member to a vehicle, such that when said rigid member is inserted into a trench at an angle to horizontal and propelled, said first side edge and said second side edge engage sidewalls of said trench and said bottom edge engages a bottom of said trench and crumbs flow from said bottom of said trench towards said top edge of said rigid member and out of said trench, thereby cleaning said trench; and

a depth pad coupled to said rigid member to allow said rigid member to float on a bottom of said trench and extract loose crumbs.

2. The trench cleaning apparatus of claim 1, further comprising a crumb controlling member coupled to said rigid member wherein said crumbs which are transported out of said trench are controlled by said crumb controlling member.

3. The trench cleaning apparatus of claim 2, wherein said crumb controlling member is a bucket.

4. The trench cleaning apparatus of claim 2, wherein said crumb controlling member is a blade.

5. The trench cleaning apparatus of claim 2, further comprising a mounting bracket for adjustable attaching said trench cleaning apparatus to said crumb controlling member.

6. The trench cleaning apparatus of claim 2, further comprising a mounting brackets for attaching said rigid member to said crumb controlling member wherein said crumb controlling member allows crumb removal of crumbs above said trench.

7. The trench cleaning apparatus of claim 2, wherein said rigid member is adjustable in relationship to said crumb controlling member to accommodate trench depth.

8. The trench cleaning apparatus of claim 1, wherein said first side edge, said second side edge and said bottom edge are cutting edges.

9. The trench cleaning apparatus of claim 1, wherein said rigid member is adjustable in width.

10. The trench cleaning apparatus of claim 1, wherein said rigid member is further comprised of a means for automatically adjusting said rigid member in length responsive to a leveling system.

11. The trench cleaning apparatus of claim 1, wherein said bottom edge of said rigid member is semi-circular.

12. The trench cleaning apparatus of claim 1, further comprising a depth guide coupled to said rigid member.

13. The trench cleaning apparatus of claim 1, further comprising a compaction roller attached to said rigid member.

14. The trench cleaning apparatus of claim 9, further comprising width sensors for automatically adjusting the width of said rigid member to a width of said trench.

15. The trench cleaning apparatus of claim 1, further comprising a spring-loaded mounting bracket allowing said trench cleaning apparatus to move laterally in relationship to said tractor.

16. The trench cleaning apparatus of claim 1, further comprising a trench sensor for increasing a length of said rigid member when said rigid member is inserted into said trench to a pre-excavated depth.

17. A trench cleaning apparatus for extricating crumbs from a trench, the trench cleaning apparatus comprising:

a rigid member having a top edge, a bottom edge, a first side edge and a second side edge, said rigid member being adjustable in width;

means for removably attaching said rigid member to a vehicle, such that when said rigid member is inserted into a trench at an angle to horizontal and propelled, said first side edge and said second side edge engage sidewalls of said trench and said bottom edge engages a bottom of said trench and crumbs flow from said bottom of said trench towards said top edge of said rigid member and out of said trench, thereby cleaning said trench.

18. The trench cleaning apparatus of claim 17, further comprising width sensors for automatically adjusting the width of said rigid member to a width of said trench.

19. A trench cleaning apparatus for extricating crumbs from a trench, the trench cleaning apparatus comprising:

a rigid member having a top edge, a bottom edge, a first side edge and a second side edge;

means for removably attaching said rigid member to a vehicle, such that when said rigid member is inserted into a trench at an angle to horizontal and propelled, said first side edge and said second side edge engage sidewalls of said trench and said bottom edge engages a bottom of said trench and crumbs flow from said bottom of said trench towards said top edge of said rigid member and out of said trench, thereby cleaning said trench; and

means for automatically adjusting said rigid member in length responsive to a leveling system.

20. A trench cleaning apparatus for extricating crumbs from a trench, the trench cleaning apparatus comprising:

a rigid member having a top edge, a bottom edge, a first side edge and a second side edge;

means for removably attaching said rigid member to a vehicle, such that when said rigid member is inserted into a trench at an angle to horizontal and propelled, said first side edge and said second side edge engage sidewalls of said trench and said bottom edge engages a bottom of said trench and crumbs flow from said bottom of said trench towards said top edge of said rigid member and out of said trench, thereby cleaning said trench; and

a depth guide coupled to said rigid member.
