Abstract

Soil treating systems and shearing assemblies for use in forestry operations are described. Embodiments of soil treating systems include a movement assembly having a front end and a back end, a shearing assembly mounted on the front end of the movement assembly, and leveling assembly mounted on the back end of the movement assembly. In some embodiments shearing assemblies are inverted V-type shearing assemblies. Further aspects described are directed towards methods for using soil treating systems and shearing assemblies for preparing land for interplanting an energy crop with a primary crop.

Claims

1. A soil treating system comprising:

a movement assembly having a front end and a back end;

a shearing assembly mounted on the front end of the movement assembly, the shearing assembly comprising;

a frame having two opposing sides;

a substantially V-shaped cutting blade having an apex, the substantially V-shaped cutting blade arranged on the frame between the two opposing sides so that the apex points towards the movement assembly; and

a filtering mechanism mounted on the frame behind the substantially V-shaped cutting blade, the filtering mechanism being configured to filter soil and plantation debris;

a leveling assembly mounted on the back end of the movement assembly.

2. The soil treating system of claim 1 wherein the shearing assembly further comprises a deflector mounted on the frame behind the substantially V-shaped cutting blade, the deflector being configured to deflect soil and plantation debris onto the soil filtering mechanism.

3. The soil treating system of claim 1 wherein the substantially V-shaped cutting blade is a serrated cutting blade.

4. The soil treating system of claim 1 wherein the leveling assembly comprises:

one or more mounting assemblies; and

a plurality of grading devices attached to the each of the one or more mounting assemblies, the plurality of grading devices being disposed angularly with respect to one another in a configuration to effect grading of soil;

wherein each of the one or more grading devices are selected from the group consisting of blades and rakes.

5. The soil treating system of claim 1 wherein the filtering mechanism comprises a screen having one or more openings, the one or more openings being large enough to allow soil to pass through the screen and small enough to prevent plantation debris from passing through the screen.

6. The soil treating system of claim 1 wherein the filtering mechanism further comprises one or more plantation debris discharge devices configured to remove plantation debris from the filtering mechanism.

7. The soil treating system of claim 1 wherein the shearing assembly and the leveling assembly are each detachable from the movement assembly.

8. The soil treating system of claim 1 wherein the movement assembly is a prime mover or a tractor.

9. A soil treating system comprising:

a movement assembly having a front end and a back end;

a shearing assembly mounted on the front end of the movement assembly, the shearing assembly comprising;

a blade mounting assembly;

a substantially V-shaped serrated cutting blade having an apex, the substantially V-shaped serrated cutting blade arranged on the blade mounting assembly so that the apex points towards the movement assembly; and

a leveling assembly mounted on the back end of the movement assembly, the leveling assembly comprising a plurality of grader blades, the plurality of grader blades being positioned to effect grading of the soil.

10. The soil treating system of claim 9 wherein the plurality of grader blades are disposed angularly with respect to one another.

11. The soil treating system of claim 9 wherein the shearing assembly and the leveling assembly are each detachable from the movement assembly.

12. The soil treating system of claim 9 wherein the movement assembly is a prime mover or a tractor.

13. A shearing assembly comprising:

a frame having two opposing substantially parallel sides, the frame configured to attach to a front of a mechanism for moving the shearing assembly;

a substantially V-shaped cutting blade mounted on the frame between the two opposing substantially parallel sides; and

a bar arranged between the two opposing substantially parallel sides of the frame behind the substantially V-shaped cutting blade;

wherein the substantially V-shaped cutting blade has an apex and the substantially V-shaped cutting blade is arranged on the frame so that the apex points toward the bar.

14. The shearing assembly of claim 13, further comprising a filtering mechanism mounted on the frame behind the substantially V-shaped cutting blade, the soil filtering mechanism being configured to separate soil and plantation debris.

15. The shearing assembly of claim 14, further comprising a deflector mounted on the frame behind the substantially V-shaped cutting blade, the deflector being configured to deflect soil and plantation debris onto the filtering mechanism.

16. The shearing assembly of claim 14 wherein the frame further comprises one or more plantation debris discharge devices configured to remove plantation debris from the filtering mechanism.

17. The shearing assembly of claim 14 wherein the filtering mechanism comprises a screen having one or more openings, the one or more openings being large enough to allow soil to pass through the screen and small enough to prevent plantation debris from passing through the screen.

18. The shearing assembly of claim 13 wherein the substantially V-shaped cutting blade is a serrated cutting blade having a plurality of teeth.

19. The shearing assembly claim 13, further comprising one or more connection mechanisms mounted on the bar, the one or more connection mechanisms being configured to mount the shearing assembly on a movement assembly.
