Description

Technical Field

[0001] The present invention relates to a firewood splitting device. Background Art

[0002] Firewood splitters are mainly used to split large or irregularly shaped wood into small pieces for easy use, and are widely used in households, rural areas, forest areas and wood processing scenarios. Current firewood splitters are driven by electric, hydraulic or lever principles, greatly reducing manual labor. For example, an electric firewood splitter can quickly process wood with a large diameter and long length, and its efficiency far exceeds that of a traditional axe. A hydraulic firewood splitter uses a high-pressure system to easily split hard wood blocks and is suitable for industrial-level operations. It has strong adaptability and can handle various types of wood (softwood, hardwood) and special-shaped wood (such as wood with knots or twists). Some models also support processing into firewood of a unified specification for easy storage and use. However, electric firewood splitters have relatively serious noise and vibration problems. Electric or hydraulic models generate relatively large noise and vibration during operation, which may affect the operator's comfort in the long term and even cause damage to hearing. In addition, they have high energy consumption and high operating costs, relying on electricity or fuel for driving (such as chainsaws, hydraulic presses), resulting in high energy consumption, especially in large-scale operations where the cost increases significantly. The maintenance complexity and cost also increase. Electric and hydraulic equipment requires regular maintenance (such as changing hydraulic oil, cleaning debris), and some precision components are prone to wear, increasing the long-term use cost.

[0003] Currently, manual firewood splitters have also emerged. The invention patent CN215471796U discloses a wall-mounted firewood splitter with multiple cutting modes, including a rack, a fixing part arranged on the rack, and a cutter horizontally rotatably connected to the rack; multiple steps are arranged on the rack for the grooves of the cutter; a first through hole penetrating the groove is arranged at the top of the rack, a rotating shaft is inserted in the first through hole, and the cutter is rotatably connected to the rack through the rotating shaft; the cutter is provided with at least one blade body and a handle for connecting the blade body. The firewood splitter is installed on the wall. According to the length of the log, it is placed on the corresponding step, and then the wood is pushed down to cut the log in half. However, when placing the firewood in the above-mentioned prior art, the current firewood is generally cut round logs. When placing it, the blade edge of the cutter first contacts the side of the outer circle of the firewood. If the firewood is bent or the force is offset, it is easy to cause the firewood to fall during the splitting process, or a greater offset may occur, easily causing the firewood splitter to fall over, etc. There is still a certain risk and the stability is poor. Summary of the Invention

[0004] To solve the above problems, the purpose of the present invention is to provide a firewood splitting device.

[0005] To achieve the above object, the technical solution of the present invention is: a firewood splitting device, including a rack and a manual strapping machine tensioner slidably arranged on the rack. A handle for pushing the slider of the manual strapping machine to move unidirectionally is rotatably arranged on one side of the manual strapping machine tensioner. A block structure for returning the slider of the manual strapping machine to its original position is also arranged on the same side of the handle. One end of the rack is vertically fixed with a splitting knife, and the cutting edge of the splitting knife faces the pressing plate. A pressing plate located on the same side as the splitting knife is fixed to one side of the slider of the manual strapping machine tensioner. Both ends of the rack are respectively fixed with a bracket structure fixedly connected to the wall, and the rack is supported away from the wall through the bracket structure.

[0006] Further, the bracket structure is composed of two symmetrical L-shaped fixing plates on the left and right. One end of the L-shaped fixing plate is fixedly connected to the rack, and the other end is respectively provided with a hollow fixing hole.

[0007] Further, the cross-section of the pressing plate is a right trapezoid, and the bottom surface of the right trapezoid of the pressing plate is fixedly connected to the slider of the manual strapping machine tensioner.

[0008] Further, one end of the cutting edge of the splitting knife is fixedly connected to the rack vertically.

[0009] Further, the rack and the bracket structure are fixedly connected by welding.

[0010] Further, each bracket structure is respectively fixed to the wall through bolts and nuts passing through the fixing holes.

[0011] When the present invention is used for splitting firewood, by swinging the handle of the manual strapping machine tensioner up and down, the slider of the manual strapping machine tensioner can be continuously pushed to move unidirectionally downward. The firewood is vertically placed between the cutting edge of the splitting knife and the pressing plate. As the slider of the manual strapping machine tensioner moves downward continuously, the firewood is pushed towards the cutting edge, so that the cutting edge splits the firewood. After splitting, a block structure for returning the slider of the manual strapping machine to its original position is also arranged on the same side of the handle. Just return the slider of the manual strapping machine to its original position, which is convenient for continuous use of splitting firewood. The handle forms a labor-saving lever structure. During the process of splitting firewood, the pressing plate moves along the direction of the rack. When splitting firewood, the splitting knife does not move and the pressing plate moves. The pressing plate pushes the firewood, and the force on the firewood is more uniform and stable during the whole process of splitting firewood. It is not only more labor-saving to split firewood, but also can better keep the firewood moving in the vertical plane where the rack is located, and the force for splitting firewood will not deviate. It can also effectively avoid the occurrence of the splitting device falling over, and the use is more stable, safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
