Abstract
Description
Technical Field
[0001] The utility model relates to a firewood splitter. Background Art
[0002] A wood splitter is a tool used to split firewood. For example, the current appearance patent CN307954602S is a tool used for splitting firewood. In addition, the utility model patent CN215471796U discloses a wall-mounted wood splitter with multiple cutting modes, including a base, a fixing portion arranged on the base, and a cutter connected to the horizontal rotating shaft of the base; the base is provided with five steps for a groove for the cutter; the top of the base is provided with a first through hole penetrating the groove, a rotating shaft is inserted in the first through hole, and the cutter is connected to the rotating shaft of the base through the rotating shaft; the cutter is provided with 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 the length of the log, and then the cutter is downward to cut the log into two. However, when placing firewood in the above-mentioned prior art, the current firewood is generally cut round logs. When placing, the blade of the cutter first contacts the side of the outer circle of the firewood. If the firewood is bent or shifted by force, it is easy to cause the firewood to fall during the chopping process, or a larger shift may occur, which may easily cause the firewood splitter to fall over, etc. There are still certain risks and poor stability. Utility Model Content
[0003] To solve the above problems, the purpose of the utility model is to provide a firewood splitter.
[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a wood splitter, comprising a base and a chopping knife vertically arranged at one end of the base, a pressure rod is rotatably arranged at the other end of the base through a rotating shaft structure, and one end of the pressure rod is rotatably connected to the base, and the other end is a pressing end for applying force, the middle part of the pressure rod is rotatably connected to one end of a push rod, and the other end of the push rod is rotatably connected to a push plate below the pressing end of the pressure rod, a guide rod is arranged between the pressure rod and the base, the guide rod is parallel to the surface of the base, and one end of the guide rod is fixedly connected to the push plate, the push surface of the push plate is opposite to the blade of the chopping knife, and the other end of the guide rod passes through the protrusion of the rotatable connection part between the pressure rod and the base.
[0005] Furthermore, a supporting roller is arranged on the surface of the base below the guide rod, and a roller part of the supporting roller is used to support the guide rod.
[0006] Further, the supporting roller is fixed on the lower surface of the guide rod, and the roller part of the supporting roller is supported on the surface of the base.
[0007] Furthermore, the main body of the pressure rod is divided into two parts, the pressure rod at the other end is provided with a handle, and the ends of the left and right parts of the pressure rod main body are respectively rotatably connected to the two sides of one end of the base through a rotating shaft structure. There are also two push rods, and the two ends of each push rod are respectively rotatably connected to the opposite side of the pressure rod and the push plate.
[0008] Furthermore, the splitting knife is vertically fixed on an arched fixing seat, and one end of the splitting knife of the base is provided with multiple seat grooves that match the fixing seat. The fixing seat is located in one of the seat grooves, and threaded holes are opened on both sides of the seat groove and the fixing seat. The fixing seat is fixedly connected to the seat groove by bolts passing through the threaded holes.
[0009] Furthermore, mounting plates with mounting holes are respectively provided on both sides of each end of the base.
[0010] Furthermore, the pressure rod is bent upward at a position where it is rotatably connected to the push rod.
[0011] Furthermore, the base is a square tube structure.
[0012] When the utility model is used for chopping wood, the pressure rod forms a labor-saving lever structure. After the pressure rod is pressed down, it pushes the push rod and then pushes the push plate to move in the direction of the blade of the chopping knife, so that the wood between the chopping knife and the push plate is split. In this process, the movement of the push plate is always guided by the guide rod and moves in a direction parallel to the surface of the base. When chopping wood, the chopping knife does not move but the push plate moves, and the push plate pushes the wood to be subjected to a more uniform and stable force in the whole process of chopping wood. Not only is it more labor-saving and can ensure the efficiency of chopping wood, but the pressure rod can be better kept moving in the vertical plane where the base is located, and the pressure will not deviate when pressed, and the occurrence of the wood splitter tilting can also be effectively avoided, so that the use is more stable, safe and reliable.
