Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood splitter blade technology, specifically to a three-blade fixed blade for a wood splitter. Background Technology
[0002] The wood splitter is a key piece of equipment in the initial processing of wood and is indispensable in the papermaking, artificial board and wood pulp processing industries. The wood splitter uses a three-blade fixed blade, which is an innovative blade. It consists of three blades, one horizontal and two vertical, forming a "∏" shape. This blade replaces the traditional single blade, splitting the log into four pieces in one pass, thus increasing efficiency many times over. In addition, the cutting edge and the rear edge are formed into a trumpet shape, which helps to reduce the load on the hydraulic push plate and ensure safe discharge.
[0003] After a knife has split wood, wood chips are usually left on the blade. These wood chips increase the friction between the knife and the wood, causing the knife to consume more energy when splitting wood, resulting in a slower splitting speed and reduced efficiency.
[0004] Therefore, a three-blade fixed blade for a wood splitter is proposed. Utility Model Content
[0005] The purpose of this utility model is to solve the problem of wood chips remaining on the blade. This utility model provides a three-blade fixed blade for a wood splitter.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A three-piece fixed blade for a wood splitter includes a wood splitter blade, with fixed plates fixedly connected to the left and right sides of the wood splitter blade, and brushes provided on the top of each fixed plate. Movable plates are provided on the left and right sides of the wood splitter blade, with movable rods fixedly connected to the bottom of each movable plate. A cleaning component is provided on the wood splitter blade, and a fixed component is provided on the wood splitter blade.
[0008] Furthermore, the cleaning component includes a bevel gear one fixedly connected to the bottom of the movable rod, a stepper motor is provided on the rear side of the bottom of the fixed plate, the output end of the stepper motor is fixedly connected to a rotating shaft, and the output end of the rotating shaft is fixedly connected to a bevel gear two.
[0009] Furthermore, the bottom of the brush is in contact with the wall of the wood splitter blade.
[0010] Furthermore, the fixing component includes hooks movably connected to the front side of the movable plate and the rear side of the brush, with a compression spring fixedly connected between the hooks.
[0011] Furthermore, the fixing component includes a limiting groove on the rear side of the movable plate, and limiting blocks are fixedly connected to the front side of the brush.
[0012] Furthermore, support plates are fixedly connected to the front and rear sides of the bottom of the fixed plate.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model splits logs with wood splitter blades. When the external controller is activated, two stepper motors start simultaneously. The stepper motors drive the rotating shaft to rotate in the forward and reverse directions respectively through the output end. During the rotation of the rotating shaft, the second bevel gear rotates, which in turn drives the first bevel gear meshing with it to rotate. The first bevel gear then drives the movable plate and brush to rotate through the movable rod. During the rotation of the movable plate, the wood chips on the surface of the wood splitter blades are cleaned, avoiding the need for the wood splitter blades to apply multiple forces to split the logs.

[0023] like Figures 1 to 3 As shown, a three-piece fixed blade for a wood splitter includes a wood splitter blade 1, which is the main body. Fixed plates 2 are fixedly connected to the left and right sides of the wood splitter blade 1. A brush 201 is provided on the top of each fixed plate 2, with the output end of the brush 201 fitting against the wall surface of the wood splitter blade 1. Movable plates 202 are provided on the left and right sides of the wood splitter blade 1, with a movable rod 203 fixedly connected to the bottom of each movable plate 202. A cleaning assembly 3 for driving the brush 201 to rotate is provided on the wood splitter blade 1. Figure 2 As shown, specifically, the cleaning component 3 includes a bevel gear 301 fixedly connected to the bottom of the movable rod 203, a stepper motor 302 is provided on the rear side of the bottom of the fixed plate 2, the output ends of the stepper motor 302 are all fixedly connected to a rotating shaft 303, the output ends of the rotating shaft 303 are all fixedly connected to a bevel gear 304, and the bevel gear 304 meshes with the bevel gear 301.
[0024] More specifically, the log is split by the wood splitter blade 1, the external controller is started, and two stepper motors 302 start simultaneously. The stepper motors 302 drive the rotating shaft 303 to rotate in the forward and reverse directions respectively through the output end. During the rotation of the rotating shaft 303, the second bevel gear 304 rotates. The second bevel gear 304 drives the first bevel gear 301 meshing with it to rotate. The first bevel gear 301 then drives the movable plate 202 and the brush 201 to rotate through the movable rod 203. During the rotation, the movable plate 202 cleans the wood chips on the surface of the wood splitter blade 1, so as to avoid the wood splitter blade 1 needing to exert force multiple times to split the log.
[0025] The wood splitter blade 1 is equipped with a fixing component 4 for easy installation and removal of the brush 201, such as... Figure 3As shown, specifically, the fixing component 4 includes a hook 401 movably connected to the front side of the movable plate 202 and the rear side of the brush 201. A compression spring 402 is fixedly connected between the hooks 401. A limiting groove 403 is opened on the rear side of the movable plate 202. A limiting block 404 is fixedly connected to the front side of the brush 201. The limiting blocks 404 are located inside the limiting groove 403.
[0026] More specifically, firstly, the limiting block 404 is placed inside the limiting groove 403. Then, by the tension of the compression spring 402, the hook 401 can be pulled to move away from each other. The hook 401 is placed on the front side of the movable plate 202 and the rear side of the brush 201 respectively. By the tension of the compression spring 402, the hook 401 is pulled to fix the movable plate 202 and the brush 201.
[0027] Support plates 5 are fixedly connected to the front and rear sides of the bottom of the fixed plate 2. The stepper motor 302 is fixedly connected to the wall of the support plate 5, and the output end of the rotating shaft 303 is movably connected to the inside of the support plate 5.
[0028] More specifically, the support plate 5 is used to support the position of the rotating shaft 303 on the wood splitter blade 1, thereby enabling the subsequent work of the rotating shaft 303.
[0029] In summary: The log is split by the wood splitter blade 1, the external controller is activated, and the two stepper motors 302 start simultaneously. The stepper motors 302 drive the rotating shaft 303 to rotate in the forward and reverse directions respectively via their outputs. During rotation, the rotating shaft 303 drives the second bevel gear 304, which in turn drives the meshing bevel gear 301. The first bevel gear 301, in turn, drives the movable plate 202 and the brush 201 to rotate via the movable rod 203. During the rotation process, the wood chips on the surface of the wood splitter blade 1 are cleaned to prevent the wood splitter blade 1 from having to use force multiple times to split the log. The limiting block 404 is placed inside the limiting groove 403. Then, by compressing the tension of the spring 402, the hook 401 can be pulled to move away from each other. The hook 401 is placed on the front side of the movable plate 202 and the back side of the brush 201 respectively. By compressing the tension of the spring 402, the hook 401 is pulled to fix the movable plate 202 and the brush 201.
