68 results about "Log splitter" patented technology

A log splitter is a piece of machinery or equipment used for splitting firewood from softwood or hardwood logs that have been pre-cut into sections (rounds), usually by chainsaw or on a saw bench. Many log splitters consist of a hydraulic or electrical rod and piston assembly and these are often rated by the tons of force they can generate. The higher the force rating, the greater the thickness or length of the rounds that can be split. The log splitter consists of all four major hydraulic components.

Quad wedge tip up log splitter

A uniquely configured quad wedge allows for the creation of a tip-up log splitter that is capable of multiple splits in a single stroke of the drive mechanism. The quad wedge is attached to the piston of a hydraulic cylinder, and is slidably mounted to a framework to allow for movement through a splitting zone. The quad wedge further includes a main splitting blade, along with a pair of splitting wings extending outwardly in a perpendicular manner. The blades each have structures on the ends thereof which are configured to help contain a log during splitting operations, thus avoiding undesired movement or wandering. The log splitter further includes a stripper mechanism positioned near the cylinder housing to allow jammed logs to be easily removed, which includes a recess to house the quad wedge when retracted. A jammed log will necessarily contact the stripper mechanism, causing it to be removed from the blade.

A new or retrofit block hoist for conventional, hydraulic-powered log splitters assists in the lifting, maneuvering, and positioning of large diameter, heavy logs that require multiple radial splits to section them for firewood, comprising a boom, pulley and cable system. A boom assembly is secured to the top end of the splitter guide beam and pulleys guide a lifting cable anchored to the wedge slide to a log section retainer means (dog or awl). The upward, hydraulically-powered movement of the cutting wedge along the I-beam lifts the log section as the wedge is raised into its upward, retracted position. Once lifted, the log is swung into position between the wedge and splitter foot plate. The wedge is then power extended (lowered), splitting the log. An optional turntable is securable to the footplate. The inventive block hoist can be provided as a kit.

Single post convertible split wedge system

This log splitter is designed to work very fast and efficiently, yet be less expensive to construct than comparable splitters. By using a single, vertical, rectangular post to support all the split wedges including the two-way, these wedges can be of a simpler, less expensive, yet as strong construction. Secondly, by angling the Split Wedge Post slightly forward, it retains the split wedges during splitting operations, limits them to rise only slightly as the wood passes through, yet allows them to be freely and easily placed and removed by hand by the operator. The manually operated Height Adjuster Bar located conveniently on the side of the beam, allows the operator to easily and quickly raise and lower the split wedges as necessary to accommodate different sized logs and to retain the wedges in place with a simple latch type arrangement.

Single cylinder hydraulic log lifter

This invention adds a very large (24×32 inch or larger) log table permanently mounted to the log splitter. This alone adds immeasurably to the efficiency and convenience of splitting. It allows for the true, convenient, and safe one-man operation of a splitter because it catches and stores the far side of the log and log pieces while the operator is free to handle the near side with one hand and the control valve with the other hand. The log lifter is powered hydraulically with the same cylinder, control valve, hoses and fittings that power the split wedge. Very simply, a cable and a pulley are used to direct the force of the existing cylinder to raise the log lifter. This simplicity lowers the cost of the log lifter considerably and makes it and the log table and the convenience of splitting in a more comfortable, standing position more readily available to the splitting public.
