Description

Technical Field

[0001] This utility model relates to a wood-splitting device. Background Technology

[0002] Wood splitters are primarily used to split large or irregularly shaped pieces of wood into smaller, usable pieces, and are widely used in homes, rural areas, forestry areas, and wood processing. Current wood splitters are driven by electric, hydraulic, or lever principles, significantly reducing manual labor. For example, electric wood splitters can quickly process large-diameter, long pieces of wood, far exceeding the efficiency of traditional axes. Hydraulic wood splitters utilize high-pressure systems to easily split hard wood blocks, suitable for industrial-grade operations; they are highly adaptable, handling various types of wood (softwood, hardwood) and specially shaped wood (such as knotted or twisted wood), and some models even support processing into uniformly sized firewood for easy storage and use. However, electric wood splitters have serious noise and vibration problems. Electric or hydraulic models generate significant noise and vibration during operation, which may affect the operator's comfort and even damage their hearing with long-term use. In addition, they have high energy consumption and high operating costs. Relying on electricity or fuel (such as chainsaws and hydraulic presses) leads to high energy consumption, especially with a significant increase in costs during large-scale operations. Maintenance complexity and costs also increase. Electric and hydraulic equipment require regular maintenance (such as changing hydraulic oil and cleaning debris), and some precision parts are prone to wear and tear, increasing long-term operating costs.

[0003] Manual wood splitters have also emerged. Utility model patent CN215471796U discloses a wall-mounted wood splitter with multiple cutting modes, including a rack, a fixing part on the rack, and a cutter connected to the rack's horizontal rotating shaft. The rack has five steps for grooves in the cutter's grooves. A first through hole is provided at the top of the rack, penetrating the grooves, and a rotating shaft is inserted into the first through hole. The cutter is connected to the rack's rotating shaft via the rotating shaft. The cutter has at least one blade and a handle for connecting the blade. The wood splitter is installed on the wall, and the log is placed on the corresponding step according to its length. Then, the cutter points downwards, splitting the log in two. However, in the aforementioned prior art, the wood is generally pre-cut round logs. When placing the log, the blade first contacts the outer edge of the log. If the log bends or shifts due to force, it is easy for the log to fall during the splitting process, or for it to shift further, potentially causing the wood splitter to tip over. This still carries a certain risk and indicates poor stability. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a wood-splitting device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a firewood splitting device, including a rack and a manual baler tensioner slidably mounted on the rack. A handle is rotatably mounted on one side of the manual baler tensioner to push the sliding block of the manual baler tensioner to move in one direction. A lever structure for returning the sliding block of the manual baler tensioner to its original position is also provided on the same side of the handle. A splitting blade is vertically fixed at one end of the rack, with the blade facing the pressure plate. A pressure plate located on the same side of the splitting blade is fixed on one side of the sliding block of the manual baler tensioner. Support structures that are fixedly connected to the wall are fixed at both ends of the rack, and the rack is kept away from the wall by the support structures.

[0006] Furthermore, the support structure consists of two symmetrical L-shaped fixing plates, one end of which is fixedly connected to the rack, and the other end is provided with hollow fixing holes.

[0007] Furthermore, the pressure plate has a right-angled trapezoidal cross section, and the bottom side of the right-angled trapezoidal pressure plate is fixedly connected to the sliding block of the tensioner of the manual packing machine.

[0008] Furthermore, one end of the blade of the cleaver is fixedly connected to the rack perpendicularly.

[0009] Furthermore, the rack and the support structure are fixedly connected by welding.

[0010] Furthermore, each support structure is fixed to the wall surface by bolts and nuts that pass through the fixing holes.

[0011] When used for splitting firewood, this invention allows the manual baler tensioner handle to be swung up and down, continuously pushing the tensioner sliding block downwards in one direction. The firewood is placed vertically between the splitting blade and the pressure plate. As the tensioner sliding block moves downwards, it pushes the firewood towards the blade, causing the blade to split the firewood. After splitting, a lever structure is provided on the same side of the handle for the tensioner sliding block to return to its original position, facilitating continued firewood splitting. The handle forms a force-saving lever structure. During the firewood splitting process, the pressure plate moves along the direction of the rack. The splitting blade remains stationary while the pressure plate moves, and the pressure plate pushes the firewood, resulting in more even and stable force distribution throughout the splitting process. This not only makes splitting firewood less strenuous but also better maintains the firewood within the vertical plane of the rack, preventing the splitting force from shifting and effectively preventing the firewood splitter from tipping over. This makes the use more stable, safe, and reliable. Attached Figure Description
