Abstract

Claims (29)

1. A splitting device for a log splitter comprising:

a support structure with a slot therein and at least one stop;

an elongate beam having an outer surface, a first end, and a second end, the elongate beam nestable beneath an outer surface of the support structure, wherein the elongate beam includes an open center portion between the first end and the second end, the elongate beam further comprising a mount member extending from the second end of the elongate beam and into the open center portion, wherein the mount member comprises one or more substantially flat plate members with a pin receiving aperture extending therethrough; and

a splitting wedge coupled to the elongate beam near the first end, the splitting wedge arranged substantially perpendicular to the outer surface of the elongate beam and including at least one splitting surface formed thereon, the splitting wedge extending through the slot in the support structure.

2. The splitting device of claim 1 , wherein the open center portion of the elongate beam is structured to receive a drive mechanism.

3. The splitting device of claim 1 , further comprising one or more bracket members positioned within the open center portion of the elongate beam for providing structural support to the beam.

4. A log splitter comprising:

a support structure having a first end, a second end, and an open center portion defined therebetweeen, the support structure defining a slot;

a splitting device slidably coupled to the support structure, the splitting device comprising:

an elongate beam having an outer surface, a first end, a second end, an open center portion between the first end and the second end, wherein the elongate beam is disposed within the open center portion of the support structure, the elongate beam further comprising a mount member extending from the second end of the elongate beam and into the open center portion, the mount member comprising one or more substantially flat plate members with a pin receiving aperture extending therethrough; and

a splitting wedge coupled to the outer surface of the elongate beam and extending through the slot in the support structure, the splitting edge including at least one splitting surface formed thereon; and

a drive mechanism disposed within the open center portion of the elongate beam, the drive mechanism coupled on a first end to the first end of the support structure and on a second end to the second end of the elongate beam.

5. The log splitter of claim 4 , wherein the drive mechanism is a hydraulic cylinder positioned within the elongate beam.

6. The log splitter of claim 4 , further comprising a wheel assembly coupled to the support structure.

7. The log splitter of claim 6 , further comprising a hitch member extending from the support structure.

8. The log splitter of claim 4 , wherein the splitting wedge is a dual splitting wedge having first and second splitting surfaces.

9. The log splitter of claim 4 , wherein the support structure further comprises a mount member extending from the first end of the support structure and into the open center portion of the structure.

10. The log splitter of claim 4 , further comprising a pair of longitudinally spaced stop members coupled to the support structure and defining a splitting zone therebetween, the splitting wedge extending into the splitting zone.

11. The log splitter of claim 4 , further comprising a three point mounting system coupled to the support structure and adapted for attachment to a three point hitch.

12. A log splitting system comprising:

a support structure having a first end, a second end, and an open center portion defined therebetweeen, the support structure defining an aperture;

a splitting device slidably coupled to the support structure, the splitting device comprising:

an elongate beam having an outer surface, a first end, a second end, and an open center portion between the first end and the second end, wherein the elongate beam is disposed within the open center portion of the support structure; and

a splitting wedge coupled to the outer surface of the elongate beam, the splitting wedge including at least one splitting surface formed thereon, the splitting wedge extending through the aperture in the support structure;

a drive mechanism disposed within the open center portion of the elongate beam; and

first and second longitudinally spaced stop members coupled to the support structure; wherein the drive mechanism is structured to drive the splitting device between a retracted position wherein the splitting wedge is positioned adjacent the first stop member and an extended position wherein the splitting wedge is positioned adjacent the second stop member and wherein a portion of the elongate beam extends through an opening in the second end of the support structure when the splitting device is driven to the extended position.

13. The log splitting system of claim 12 , wherein the splitting wedge is a dual splitting wedge having first and second splitting surfaces.

14. The log splitting system of claim 12 , wherein the drive mechanism comprises:

a hydraulic cylinder coupled to the first end of the support structure, wherein a piston of the hydraulic cylinder is extendable to drive the splitting device between the retracted position and the extended position.
