Abstract
Description
Technical Field
[0001] This invention relates to the field of wood splitting machine technology, specifically to a convenient tracked wood splitting machine with fast loading. Background Technology
[0002] Wood splitters are core material preparation equipment in the paper, engineered wood, and wood pulp processing industries. They use hydraulic or mechanical power to split large timber, stumps, and other raw materials into sizes that meet the processing requirements of wood chippers. The equipment can be divided into two structural types: vertical and horizontal. The household type has a simple design and is suitable for splitting small pieces of wood, while the industrial type has a thrust of 30-60 tons and a processing capacity of 4,000 kg / hour. It adopts high-strength steel blades, adjustable blades, and a V-shaped feeding platform to achieve a balance between wood chip precision and safe operation.
[0003] Wood splitters are heavy steel products. Previously available wood splitters were either trailer-mounted or manually moved, unable to move on their own and requiring a vehicle to tow them or manual labor. They are unsuitable for landscaping and timber processing, and cannot be moved on hills, slopes, or uneven roads.
[0004] The original wood splitters on the market were cumbersome to operate. Moving the wood and operating the hydraulic rods were not in the same position. People had to walk around the machine, which was time-consuming, fuel-consuming, labor-intensive, and inefficient. In addition, the original wood splitters required people to manually move the wood onto the machine before splitting it. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a convenient and easy-to-operate tracked log splitter with rapid material loading, solving the problems of time-consuming, labor-intensive, and inefficient operation.

A tension adjustment assembly is provided at the other end of the bottom of the frame. A controller is fixedly connected to the middle of the top of the frame. An operating lever is provided at one end of the controller. An operating handle is threaded through and threaded to the top of the outer ring of the operating lever. An engine is fixedly connected to one side of the middle of the top of the frame. A first hydraulic cylinder is fixedly connected to one end of the support frame, and the output end of the first hydraulic cylinder is in contact with the I-beam frame.
[0007] Preferably, the feeding assembly includes a sleeve, which is rotatably connected to one end of an I-beam frame. A feeding plate is fixedly connected to the top of the sleeve, and a telescopic rod is slidably connected to the inner wall of the sleeve. One end of the telescopic rod is fixedly connected to a slanted frame plate.
[0008] Preferably, the tension adjustment component includes a fixed plate, both ends of which are fixedly connected to the other end of the bottom of the frame. Threaded rods are provided through both sides of one end of the fixed plate, and nuts are threaded to both sides of the outer ring of each threaded rod. A top block is rotatably connected to one end of the threaded rod, and the top block is slidably connected to the other end of the bottom of the frame. Tracks are provided at both ends of the top block, and a protective plate is provided on one side of each track.
[0009] Preferably, a lubrication box is fixedly connected to both ends of one side of the I-beam frame, a stop block is slidably connected through the top of the lubrication box, and a rack is fixedly connected to the bottom of the stop block, and the rack is meshed with a gear.
[0010] Preferably, both ends of the other side of the I-beam frame are fixedly connected to limit frames, and a feeding plate is provided between the limit frames.
[0011] Preferably, a support plate is rotatably connected to one middle end of the bottom of the frame, a standing plate is fixedly connected to the top of the support plate, a support rod is fixedly connected to one bottom end of the frame, and rubber pads are slidably connected to both sides of the outer wall of the support rod.
[0012] Preferably, a second hydraulic cylinder is rotatably connected to the middle of one side of the I-beam frame, and a second connecting plate is rotatably connected to the output end of the second hydraulic cylinder. The second connecting plate is fixedly connected to the bottom of the sleeve frame. A rotating rod is fixedly connected between the sleeve frames, and gears are fixedly connected to both ends of the outer ring of the rotating rod.
[0013] Preferably, the inner wall of the chassis is provided with a fixing frame, one end of the fixing frame is fixedly connected to a first handle, and the outer wall of the first handle is fixedly connected to a second handle.
[0014] Working Principle: After the equipment starts, the gasoline engine provides power, simultaneously meeting the needs of hydraulic cylinder splitting and track movement, eliminating the need for additional towing. The operator stands on the standing plate at the bottom of the frame, using the first and second handles for stability. Rubber pads enhance standing comfort, and a support plate can store the standing plate. The loading stage is completed by the loading assembly: the operator places the timber on the inclined frame plate and controls the second hydraulic cylinder to supply oil via the operating lever. The output end of the second hydraulic cylinder drives the sleeve frame to rotate and adjust the angle through the second connecting plate. The loading plate at the top of the sleeve frame and the telescopic rod slidingly connected to the inner wall cooperate to transport the timber to the I-beam frame. When the sleeve frame rotates, it drives the rotating rod to rotate, causing the gear and rack to mesh and transmit power. The rack drives the stop block to move up and down, intercepting the timber and ensuring that only one piece of timber enters the I-beam frame at a time. The lubrication box provides lubrication for the gear and rack, and the sealing ring prevents lubricating oil leakage. During the timber splitting stage, the first hydraulic cylinder can be adjusted. The frame angle is adapted to fit the timber, and the controller provides centralized operation. Operators control the hydraulic cylinder supply via a ergonomically positioned lever and handle. The cylinder output drives the splitting blade and slider (sliding along the top of the frame) towards the baffle to split the timber. Controlling the cylinder retraction retracts the splitting blade and automatically lifts the timber into the splitting position, eliminating the need for manual handling. After one timber is split, the second hydraulic cylinder restarts, sending the next timber to the frame and repeating the splitting process. For movement and adjustment, the engine drives the hydraulic pump, and the hydraulic oil flow is adjusted to the hydraulic motor via the lever. This drives the drive wheels and driven wheels of the track, enabling the equipment to move, turn, brake, and accelerate. The tension adjustment component adjusts the track condition: rotating the nuts on both sides of the threaded rod adjusts the position of the threaded rod, causing the top block to slide, thereby adjusting the position of the tension wheel and adjusting the track tension. The protective plate protects the track.
[0015] This invention provides a convenient, tracked log splitter with rapid loading. It offers the following advantages: 1. This invention has a powerful power supply capability through a gasoline engine, which can simultaneously meet the dual needs of splitting wood with a hydraulic cylinder and moving the equipment. This design completely gets rid of the limitations of traditional equipment that relies on manual towing or vehicle transport. It not only saves additional manpower input, but also avoids the costs incurred by vehicle transportation. At the same time, the self-propelled function allows the equipment to flexibly shuttle between different work sites, greatly improving the convenience of movement and site adaptability.
[0016] 2. This invention adopts an integrated control position design, which centrally sets the control joystick in a position that is comfortable for the human body. Operators can easily complete all operations such as splitting wood, walking, turning, braking, and accelerating from a single position. This design simplifies the operation process, reduces the difficulty of operation, and reduces manual input. In addition, the unified power supply mode is more economical in terms of fuel consumption, which significantly improves the overall work efficiency in many ways.
[0017] 3. This invention uses the retraction of a hydraulic cylinder to automatically lift the wood, allowing it to be precisely positioned for the cutting blade. This completely replaces the tedious manual lifting and lowering operations of traditional methods. This function significantly reduces the labor intensity of operators and avoids fatigue and safety hazards that may result from manual handling. At the same time, the automated feeding process reduces feeding time, further improving the continuity of operations and overall efficiency. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example: Please see the appendix Figure 1-Appendix Figure 8 This invention provides a convenient, tracked log splitter with rapid loading, comprising a frame 1. A housing 2 is fixedly connected to one top end of the frame 1, and a support frame 3 is fixedly connected to the other top end of the frame 1. An I-beam 4 is rotatably connected to the top of the support frame 3. First connecting plates 11 are fixedly connected to both sides of the top end of the I-beam 4. Limiting frames 5 are provided on the outer sides of the first connecting plates 11. A hydraulic cylinder 10 is provided at one end of the inner wall of the limiting frame 5. A splitting blade 13 is fixedly connected to the output end of the hydraulic cylinder 10. A baffle 12 is fixedly connected to the other end of the I-beam 4. A feeding assembly is provided on one side of the frame 4. A slider 27 is provided at the bottom of the splitter 13 and is slidably connected to the top of the frame 4. A tension adjustment assembly is provided at the other end of the bottom of the frame 1. A controller 14 is fixedly connected to the middle of the top of the frame 1. An operating lever 19 is provided at one end of the controller 14. An operating handle 8 is threaded through and threaded to the top of the outer ring of the operating lever 19. An engine 23 is fixedly connected to one side of the middle of the top of the frame 1. A first hydraulic cylinder 9 is fixedly connected to one end of the support frame 3 and the output end of the first hydraulic cylinder 9 is in contact with the frame 4.
[0022] In use, the first hydraulic cylinder 10 is opened, and the output end of the first hydraulic cylinder 10 drives the splitting blade 13 and the slider 27 to move towards the baffle 12. The splitting blade 13 splits the wood. The oil supply valve of the operating lever 19 supplies oil to the hydraulic cylinder 10 to realize the functions of extending the splitting blade 13 (splitting wood) and retracting (retracting the splitting blade 13). The gasoline engine 23 can simultaneously supply the hydraulic cylinder for wood splitting work, or it can supply the walking work. There is no need for people to tow or vehicles to tow. The control position is integrated, and the control lever is centrally set in a position that conforms to the human body comfortably. It controls various tasks such as splitting wood, walking, turning, braking, and acceleration, greatly improving work efficiency in terms of labor, fuel costs, and other aspects. After the first piece of wood is cut, the second hydraulic cylinder 35 is started again. The second hydraulic cylinder 35 then sends the next piece of wood to the I-beam 4. The hydraulic cylinder 10 retracts and automatically lifts the wood into the splitting blade 13 position, eliminating the need for manual lifting and unloading.
[0023] Please see the appendix Figure 2 and attached Figure 5 -Appendix Figure 7The feeding assembly includes a sleeve 30, which is rotatably connected to one end of an I-beam 4. A feeding plate 31 is fixedly connected to the top of the sleeve 30. A telescopic rod 32 is slidably connected to the inner wall of the sleeve 30. A slant plate 33 is fixedly connected to one end of the telescopic rod 32. Lubrication boxes 37 are fixedly connected to both ends of one side of the I-beam 4. A stop block 40 is slidably connected through the top of the lubrication box 37. A rack 38 is fixedly connected to the bottom of the stop block 40, and the rack 38 meshes with a gear 39. Limit frames 28 are fixedly connected to both ends of the other side of the I-beam 4. A discharge plate 29 is provided between the limit frames 28. A second hydraulic cylinder 35 is rotatably connected to the middle of one side of the I-beam 4. A second connecting plate 34 is rotatably connected to the output end of the second hydraulic cylinder 35, and the second connecting plate 34 is fixedly connected to the bottom of the sleeve 30. A rotating rod 36 is fixedly connected between the sleeves 30. Gears 39 are fixedly connected to both ends of the outer ring of the rotating rod 36.
[0024] The loading and unloading of timber is achieved by supplying oil to the second hydraulic cylinder 35 via the control lever 19, which extends (lifts) and retracts (reloads) the timber. When the second hydraulic cylinder 35 is activated, it drives the sleeve 30 to adjust its angle via the connecting plate 34. The operator places the timber on the inclined plate 33, and the second hydraulic cylinder 35 lifts the sleeve 30, causing the timber to roll onto the I-beam 4. During the rotation of the sleeve 30, the rotating rod 36 rotates, which in turn rotates the gear 39, thereby causing the rack 38 to move up and down. This, in turn, intercepts the timber via the stop block 40, ensuring that there is only one timber on the I-beam 4. The gear 39 and rack 38 are lubricated by the lubrication box 37, and a sealing ring is provided at the point where the lubrication box 37 passes through the rotating rod 36 to prevent lubricating oil leakage.
[0025] Please see the appendix Figure 1 and attached Figure 4 The tension adjustment component includes a fixed plate 24. Both ends of the fixed plate 24 are fixedly connected to the other end of the bottom of the frame 1. Threaded rods 26 are provided through both sides of one end of the fixed plate 24. Nuts are threadedly connected to both sides of the outer ring of the threaded rods 26. A top block 25 is rotatably connected to one end of the threaded rod 26, and the top block 25 is slidably connected to the other end of the bottom of the frame 1. Tracks 17 are provided at both ends of the top block 25, and a protective plate 6 is provided on one side of each track 17.
[0026] The track 17 includes a track, a driven wheel, a driven wheel, and a tensioner. The position of the threaded rod 26 can be adjusted by adjusting the nuts on both sides, thereby adjusting the position of the top block 25 and thus the position of the tensioner, thereby adjusting the tension of the track 17. The track 17 can be protected by the guard plate 6. The engine 23 drives the hydraulic pump, and the hydraulic oil flow is reduced or increased by the operating lever 19 to enter the hydraulic motor, which drives the drive wheel and track to move.
[0027] Please see the appendix Figure 3 -Appendix Figure 4 A support plate 20 is rotatably connected to one end of the bottom of the frame 1. A standing plate 18 is fixedly connected to the top of the support plate 20. A support rod 21 is fixedly connected to one end of the bottom of the frame 1.
