Abstract

A machine pushed trencher assembly includes a first plate that is triangularly shaped. A pair of second plates is coupled singly to and extends transversely from opposing sides of the first plate. The second plates are coupled to define a cutting edge. A fourth plate that is coupled to a base of the first plate is configured to couple to a front end of a machine. A second bar is coupled to the fourth plate and extends angularly above the second plates. A third bar is pivotally coupled to the second bar. An actuator is coupled to the second and third bars. At least one wheel is rotationally coupled to the third bar. The machine compels the cutting edge through a substrate to prepare a trench. The actuator positions the wheel so that it rolls on a surface of the substrate to control a depth of the trench.

Claims

a first plate, said first plate being triangularly shaped;

a pair of second plates, each said second plate being coupled to and extending transversely from a respective opposing side of said first plate, said second plates being coupled proximate to an apex of said first plate defining a cutting edge;

a fourth plate coupled to and extending substantially perpendicularly from a base of said first plate, said fourth plate being configured for coupling to a front end of a machine, such as a skid loader, articulated loader, and a tracked bulldozer;

a second bar coupled to an inner face of said fourth plate, said second bar extending angularly above said second plates to proximate to said apex of said first plate;

a third bar pivotally coupled to said second bar distal from said fourth plate;

an actuator coupled to said second bar and said third bar, said actuator being configured for operationally coupling to the machine;

at least one wheel rotationally coupled to said third bar distal from said second bar; and

wherein said fourth plate is positioned on said first plate such that said fourth plate is configured for coupling to the machine such that the machine is configured for compelling said cutting edge through a substrate for preparing a trench, wherein said actuator is positioned on said second bar and said third bar such that said actuator is positioned for selectively positioning said at least one wheel relative to said apex such that said at least one wheel is configured for rolling on a surface of the substrate for controlling a depth of the trench.

2. The assembly of claim 1, further including said cutting edge being arcuate.

3. The assembly of claim 1, further including said second plates being arcuate proximate to said base of said first plate such that said second plates are configured for directing material distally from said second plates.

4. The assembly of claim 1, further including said second plate being tapered proximate to said base of said first plate such that a lower edge of each said second plate extends past said base.

5. The assembly of claim 1, further including a third plate coupled to said first plate adjacent to said apex, said third plate extending coplanarly from said first plate past said opposing sides of said first plate defining a cutting point.

6. The assembly of claim 1, further including a plurality of couplers coupled to an outer face of said fourth plate, said couplers being configured for coupling to the front end of the machine, wherein said couplers are positioned on said fourth plate such that said couplers are configured for coupling said fourth plate to the machine.

7. The assembly of claim 6, further including said plurality of couplers comprising two said couplers.

8. The assembly of claim 6, further including each said coupler comprising a first bar, a hook, an extrusion, and a penetration, said first bar being coupled vertically to said outer face of said fourth plate, said hook being coupled to and extending from an upper end of said first bar, said extrusion being coupled to and extending from a lower end of said first bar, said penetration being positioned through said extrusion, wherein said hook is positioned on said first bar such that said hook is configured for inserting a rod of the machine for coupling said fourth plate to the machine, wherein said extrusion is positioned on said first bar such that said penetration is configured for inserting a connector for coupling said extrusion to the machine and fixedly positioning said hook on the rod of the machine.

9. The assembly of claim 1, further including said second bar and said third bar being rectangularly shaped when viewed longitudinally.

10. The assembly of claim 1, further including said second bar being coupled to upper edges of said second plates proximate to said cutting edge.

11. The assembly of claim 1, further comprising:

an extension coupled to and extending from said third bar proximate to said second bar; and

said actuator comprising a hydraulic cylinder pivotally coupled to and extending between said second bar and said extension.

12. The assembly of claim 1, further including said at least one wheel comprising a pair of rollers.

13. The assembly of claim 1, further including a fifth plate coupled to and extending from said inner face of said fourth plate, said fifth plate extending to said second bar, said fifth plate being coupled to said second plates, wherein said fifth plate is positioned on said fourth plate and said second plates such that said fifth plate is positioned for bracing said second plates as said second plates contact the substrate.

14. The assembly of claim 13, further including a pair of sixth plates coupled to and extending between said fourth plate and said fifth plate, said sixth plates being triangularly shaped.
