Log splitter
A log splitter includes a trailer supporting a hydraulic pump, and a splitting beam coupled to the trailer. The splitting beam includes a housing maintaining a reservoir communicating with the hydraulic pump, and a hydraulic ram coupled to the housing, where the hydraulic ram is in communication with the reservoir and the hydraulic pump. The splitting beam is movable relative to the trailer between a first splitting position adjacent to the trailer and a second splitting position in which the splitting beam is displaced away from the trailer.
1. A log splitter comprising:
a trailer supporting a hydraulic pump, the trailer comprising a central longitudinal axis; and
a splitting beam movably coupled to the trailer by a coupling structure, the coupling structure permitting the splitting beam to move relative to the trailer between a first splitting position parallel to the central longitudinal axis of the trailer and a second splitting position in which the splitting beam is displaced above and away from and parallel to the central longitudinal axis of the trailer, the splitting beam comprising:
a housing maintaining a reservoir communicating with the hydraulic pump,
a hydraulic ram coupled to the housing, the hydraulic ram communicating with the reservoir and the hydraulic pump to operably drive the hydraulic ram toward a wedge.
2. The log splitter of claim 1 , wherein the splitting beam comprises a baffle insertable into the housing and configured to separate the reservoir into a hydraulic fluid inlet volume and a hydraulic fluid outlet volume.
3. The log splitter of claim 2 , wherein the housing comprises a tubular housing having first and second opposing ends, the first end sealed, and the baffle comprises an end plate that is sealed to the second end of the tubular housing.
4. The log splitter of claim 3 , wherein the end plate of the baffle defines an inlet port communicating with the hydraulic fluid inlet volume and an outlet port communicating with the hydraulic fluid outlet volume.
5. The log splitter of claim 2 , wherein the housing comprises a housing length and the baffle comprises a baffle length that is between about 20-95% of the housing length.
6. The log splitter of claim 1 , wherein the splitting beam comprises a first trunnion coupled adjacent to a first end of the housing and a second trunnion coupled adjacent to a second end of the housing, the first and second trunnions coupled to respective first and second risers that are pivotably coupled to the trailer.
7. The log splitter of claim 6 , wherein the trailer comprises a length-adjustable tongue.
8. The log splitter of claim 6 , wherein the risers each comprise a bumper attached to an exterior surface, the bumper configured to contact the trailer when the splitting beam is in the first splitting position adjacent to the trailer.
9. The log splitter of claim 1 wherein the coupling structure comprises a pair of risers that form a parallelogram structure between the splitting beam and the trailer.
10. The log splitter of claim 1 wherein the splitting beam is parallel to the trailer in both the first and second splitting positions.
11. A log splitter comprising:
a trailer supporting a hydraulic pump, the trailer comprising a central longitudinal axis; and
a splitting beam comprising:
a coupling structure movably coupling the splitting beam to the trailer, the coupling structure permitting the splitting beam to move relative to the trailer between a first splitting position parallel to the central longitudinal axis of the trailer and a second splitting position in which the splitting beam is displaced above and away from and parallel to the central longitudinal axis of the trailer,
a housing maintaining a reservoir communicating with the hydraulic pump,
a baffle inserted into the housing effectively separating the reservoir into an inlet volume and an outlet volume, wherein the baffle comprises an end plate and a blade extending from the end plate,
a hydraulic ram coupled to the housing and communicating with the reservoir and the hydraulic pump to operably drive the hydraulic ram toward a wedge.
12. The log splitter of claim 11 , wherein the hydraulic pump is operated by an engine coupled to the housing.
13. The log splitter of claim 11 , further comprising:
a trailer, the splitting beam movably coupled to the trailer between a first position in which the splitting beam is collapsed onto the trailer and a second position in which the splitting beam is displaced away from the trailer;
wherein the hydraulic pump is operated by an engine coupled to the trailer.
14. The log splitter of claim 11 , wherein the end plate is connected to the housing and the blade is not connected to the housing.
15. The log splitter of claim 11 , wherein the housing comprises a tubular housing sealed on a first end and sealed on a second end opposite the first end by the end plate of the baffle.
16. The log splitter of claim 11 , wherein the end plate defines an inlet port communicating with the inlet volume and an outlet port communicating with the outlet volume, a low pressure return line of the hydraulic ram coupled with the inlet port and a suction line coupled between the outlet port and an intake of the hydraulic pump.
