Description

Technical Field

[0001] This utility model relates to the field of wood splitter technology, and in particular to an adjustable cutting mechanism for wood splitters. Background Technology

[0002] As a key piece of equipment in the initial processing of wood, the height of the blades in a wood splitter directly determines the diameter range of the wood that can be processed and the splitting efficiency. In actual production, the diameter of logs varies greatly between different batches. If the blade height cannot be adjusted quickly and accurately, it will cause frequent machine downtime, repeated manual turning of the logs, significantly reducing the overall production line's output and increasing the labor intensity of operators. Therefore, some wood splitters with adjustable blade heights have appeared on the market.

[0003] For example, the Chinese utility model patent "Quickly Installable and Usable Wood Splitter" with patent publication number CN223369616U has a slot on the side of the support plate. After the blade is inserted into the slot, it is locked and positioned by connecting bolts and threaded holes on the back of the blade. When the blade height needs to be changed, the connecting bolts must be completely unscrewed first. The blade falls to the support plate under its own weight. Then, the spring tension and the supporting plate lifting force are used to complete the coarse height adjustment. Finally, the bolts are screwed back in to fix it.

[0004] However, the above adjustment process relies entirely on manual operation. The unscrewing / screwing of bolts, the control of the tool's falling position, and repositioning all require close intervention from workers, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0005] This invention addresses the problem that existing wood splitters require manual operation for height adjustment, resulting in time-consuming, labor-intensive, and inefficient adjustments. The technical problem this invention aims to solve is to provide an adjustable cutting mechanism for a wood splitter to resolve the aforementioned issues.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: 1. An adjustable cutting mechanism for a wood splitter, including a worktable and a splitting blade. The worktable is used to support the wood. The worktable has an installation channel that runs vertically through it. The installation channel is clearance-fitted with the splitting blade. The worktable is characterized in that: a support platform is provided under the worktable. A telescopic cylinder is fixedly provided on the support platform. A push rod is hinged to the end of the telescopic rod of the telescopic cylinder. A support seat is hinged to the end of the push rod. A connecting column is provided at the lower end of the splitting blade. The connection between the splitting blade and the connecting column forms a backing platform. The splitting blade is located in the installation channel and can slide vertically relative to the installation channel. The lower end of the connecting column slides through the support seat and the support platform in sequence. The upper surface of the support seat abuts against the backing platform. When the telescopic rod extends, the push rod pushes the support seat to slide upward, thereby pushing the splitting blade to slide upward to adjust the size of the splitting blade protruding from the worktable. When the telescopic rod retracts, the support seat is pulled downward by the push rod and slides down, thereby driving the splitting blade to slide down.

[0007] A further preferred embodiment of this utility model is that the telescopic cylinder is a pneumatic cylinder or a hydraulic cylinder.

[0008] A further preferred embodiment of this utility model is: the installation channel is a strip structure, and the length direction of the installation channel is consistent with the length direction of the workbench, and the axis of the length direction of the installation channel coincides with the axis of the length direction of the workbench.

[0009] A further preferred embodiment of this utility model is: the support platform is provided with a sliding hole corresponding to the connecting column, the support base is provided with a shaft hole for the connecting column to pass through, and the connecting column passes through the shaft hole and the sliding hole in sequence to slide and connect with the support base and the support platform.

[0010] A further preferred embodiment of this utility model is as follows: a U-shaped hinge seat is provided on the support base, one end of the push rod is hinged to the U-shaped hinge seat through a hinge shaft, the other end of the push rod is provided with a U-shaped hinge seat, and the end of the telescopic rod is hinged to the U-shaped hinge seat through a hinge shaft.

[0011] A further preferred embodiment of this utility model is as follows: the push rod includes a first round rod, a second round rod, and a threaded sleeve disposed between the first round rod and the second round rod. The two ends of the threaded sleeve are respectively threaded to the first round rod and the second round rod. When the threaded sleeve rotates in one direction, the distance between the first round rod and the second round rod increases; when the threaded sleeve rotates in the opposite direction, the distance between the first round rod and the second round rod decreases.

[0012] A further preferred embodiment of this utility model is as follows: the bottom of the workbench is provided with a front support frame and a rear support frame, the support platform is located between the front support frame and the rear support frame, and one end of the support platform is fixedly connected to the front support frame and the other end is fixedly connected to the rear support frame.

[0013] A further preferred embodiment of this utility model is that the top surface of the support platform and the bottom surface of the worktable have a distance between them.

[0014] A further preferred embodiment of this utility model is that the width of the support base is greater than the width of the installation channel, and the height of the chopping knife is at its maximum value when the upper surface of the support base abuts against the bottom surface of the workbench.

[0015] Compared with the prior art, this utility model has the following advantages: In this utility model, the linkage mechanism composed of the push rod and the support seat drives the push rod through the telescopic cylinder.

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0021] This embodiment mainly describes the adjustable cutting mechanism of the wood splitter, as follows: like Figures 1 to 4As shown, the adjustable cutting mechanism of the wood splitter includes a worktable 1 and a splitting blade 2. The worktable 1 supports the wood, and the splitting blade 2 splits the wood placed on the worktable 1. The worktable 1 has a vertically extending mounting channel 3 for mounting the splitting blade 2. The splitting blade 2 is installed after the mounting channel 3, and the mounting channel 3 and the splitting blade 2 are fitted with a clearance fit. A support platform 4 is provided under the worktable 1, and a telescopic cylinder 5 is fixedly installed on the support platform 4. The telescopic rod 51 of the telescopic cylinder 5 is hinged to a push rod 6, and the end of the push rod 6 is hinged to a support seat 7. The lower end of the splitting blade 2 is provided with a connecting column 8, and the connection between the splitting blade 2 and the connecting column 8 forms an abutment platform 9. The splitting blade 2 is located in the mounting channel 3 and can slide vertically relative to the mounting channel 3. The lower end of the connecting column 8 slides through the support seat 7 and the support platform 4 in sequence. The upper end surface of the support seat 7 abuts against the abutment platform 9 to support the splitting blade 2. When the telescopic rod 51 extends, the lower end of the push rod 6 moves closer to the connecting column 8 along with the telescopic rod 51, while the upper end of the push rod 6 pushes the support seat 7 to slide upward, thereby pushing the chopping blade 2 to slide upward to adjust the size of the chopping blade 2 protruding from the worktable 1; when the telescopic rod 51 retracts, the lower end of the push rod 6 gradually moves away from the connecting column 8 along with the telescopic rod 51. At this time, the support seat 7 is pulled downward by the push rod 6 and slides down along the connecting column 8. At this time, the chopping blade 2 loses the upward support force of the support platform 4 and slides downward with the support platform 4 under its own gravity. In this design, the linkage mechanism consisting of push rod 6 and support base 7 is driven by telescopic cylinder 5. Push rod 6 moves up and down with telescopic rod 51, causing support base 7 to move up and down. Support base 7 moves up and down through abutment platform 9, realizing stepless adjustment of the height of splitting blade 2, which greatly adapts to the processing needs of wood of different diameters. The entire process of adjusting splitting blade 2 does not require direct manual intervention and is remotely driven by telescopic cylinder 5, which not only saves time and effort but also greatly improves the efficiency of splitting blade 2 adjustment and effectively avoids the risk of possible hand injury.

[0022] Specifically, the telescopic cylinder 5 is a pneumatic cylinder or a hydraulic cylinder. Pneumatic cylinders or hydraulic cylinders have the characteristics of large output force, smooth operation and fast response, which can meet the requirements of speed and stability of height adjustment of the splitter 2. At the same time, the installation and maintenance of pneumatic cylinders or hydraulic cylinders are relatively simple, making them easy to use in industrial environments such as wood splitters.

[0023] like Figure 4 As shown, the installation channel 3 is a strip structure, and the length direction of the installation channel 3 is consistent with the length direction of the workbench 1. The axis of the length direction of the installation channel 3 coincides with the axis of the length direction of the workbench 1. The strip-shaped installation channel 3 can adapt to the shape and movement direction of the splitting blade 2, ensuring that the splitting blade 2 slides smoothly in the installation channel 3. At the same time, the length direction of the installation channel 3 is consistent with the length direction of the workbench 1, making the position of the splitting blade 2 on the workbench 1 more reasonable and facilitating the splitting of wood.

[0024] Specifically, the support platform 4 is provided with a sliding hole 10 corresponding to the connecting column 8, and the support base 7 is provided with a shaft hole 11 for the connecting column 8 to pass through. The connecting column 8 passes through the shaft hole 11 and the sliding hole 10 in sequence and is slidably connected to the support base 7 and the support platform 4. The sliding hole 10 and the shaft hole 11 provide stable sliding guidance for the connecting column 8, ensuring that the chopping blade 2 always maintains a vertical state during the up and down movement, avoiding the chopping blade 2 from shifting or getting stuck, and improving the accuracy and reliability of the height adjustment of the chopping blade 2.

[0025] Specifically, the support base 7 is provided with a U-shaped hinge seat 12. One end of the push rod 6 is hinged to the U-shaped hinge seat 12 via a hinge shaft 13. The other end of the push rod 6 is provided with a U-shaped hinge seat 24. The end of the telescopic rod 51 is hinged to the U-shaped hinge seat 24 via a hinge shaft 25. The U-shaped hinge seat 12 and the U-shaped hinge seat 24 provide a stable hinge structure for the connection between the push rod 6 and the support base 7 and the telescopic rod 51, so that the push rod 6 can rotate flexibly when pushing the support base 7 to move up and down, reducing wear at the hinge and improving the service life of the mechanism.

[0026] Specifically, the push rod 6 includes a first round rod 61, a second round rod 62, and a threaded sleeve 63 disposed between the first round rod 61 and the second round rod 62. The two ends of the threaded sleeve 63 are threadedly connected to the first round rod 61 and the second round rod 62, respectively. When the threaded sleeve 63 rotates in one direction, the distance between the first round rod 61 and the second round rod 62 increases; when the threaded sleeve 63 rotates in the opposite direction, the distance between the first round rod 61 and the second round rod 62 decreases. The design of the threaded sleeve 63 facilitates the installation of the push rod 6. When installing the push rod 6, first, the support seat 7 connected to the first round rod 61 is fitted onto the connecting post 8, and then the first round rod 61 and the second round rod 62 are connected through the threaded sleeve 63.

[0027] like Figure 1 and Figure 4 As shown, the bottom of the workbench 1 is provided with a front support frame 16 and a rear support frame 17. The support platform 4 is located between the front support frame 16 and the rear support frame 17, with one end fixedly connected to the front support frame 16 and the other end fixedly connected to the rear support frame 17. The front support frame 16 and the rear support frame 17 provide stable support for the support platform 4, ensuring that the support platform 4 will not shake or shift during operation, thereby improving the accuracy of the height adjustment of the splitter 2 and the overall stability of the wood splitter.

[0028] Specifically, there is a gap between the top surface of the support platform 4 and the bottom surface of the worktable 1. This gap provides sufficient space for the downward movement of the chopping blade 2, ensuring that the chopping blade 2 can smoothly descend and rise, and realizing the adjustment of the height range of the chopping blade 2.

[0029] Specifically, the width of the support base 7 is greater than the width of the installation channel 3. When the upper surface of the support base 7 abuts against the bottom surface of the workbench 1, the height of the chopping blade 2 is at its maximum value. The width of the support base 7 is greater than the width of the installation channel 3, so that when the support base 7 moves upward to a certain position, it can abut against the bottom surface of the workbench 1, thereby limiting the further rise of the chopping blade 2, playing a limiting role, ensuring the stability of the chopping blade 2 at its maximum height, and avoiding damage to the mechanism due to excessive rise.

[0030] Specifically, there is a gap between the top surface of the support platform and the bottom surface of the workbench. This gap provides sufficient space for the chopping blade to move downwards, ensuring that the chopping blade can smoothly descend and rise, and realizing the adjustment of the chopping blade height range.

[0031] Specifically, the width of the support base is greater than the width of the installation channel. When the upper surface of the support base abuts against the bottom surface of the workbench, the height of the chopping blade is at its maximum. The width of the support base is greater than the width of the installation channel, so that when the support base moves upward to a certain position, it can abut against the bottom surface of the workbench, thereby limiting the further rise of the chopping blade, playing a limiting role, ensuring the stability of the chopping blade at its maximum height, and avoiding damage to the mechanism due to excessive rise.
