Description

Technical Field

[0001] This utility model relates to the field of forestry and wood processing machinery technology, and in particular to a horizontal hydraulic wood splitter with traction function that is suitable for field operations. Background Technology

[0002] A log splitter is a mechanical device that uses a mechanical structure to divide a log into multiple strips. It is commonly used in cold regions for burning wood for warmth.

[0003] Wood splitters are divided into vertical and horizontal types. When using a horizontal wood splitter, the log can be placed flat on the worktable, and the pusher at the front of the piston rod of the hydraulic cylinder on one side pushes the log into contact with the splitting blade to complete the splitting operation. However, a vertical wood splitter requires the log to be placed vertically and stably, and a person needs to hold the log with their hand, which is more inconvenient than a horizontal wood splitter.

[0004] (1) Problems with the existing technology: Traditional horizontal log splitters are mostly fixed (such as fixed base + manual or electric hydraulic drive) or small mobile models, which have the following drawbacks: 1) Poor mobility: Most log splitters need to be carried manually or towed simply, and cannot be quickly moved to the work site by a towing vehicle (such as a tractor or pickup truck), resulting in poor adaptability; 2) Complex operation: Some models use electric hydraulic pumps or complex multi-way valve control, which rely on external power sources (such as generators or high-voltage lines) when working in the field. They cannot work when the power is cut off or the voltage is unstable. 3) Inefficient structure: The lifting and lowering of the wood splitter relies on manual assistance (such as a lever mechanism), which is inefficient and labor-intensive; the support structure is not stable enough (such as a single tire or fixed bracket), and it is easy to sway and deviate when splitting heavy loads. 4) Inconvenient loading: Logs need to be manually carried to the splitting location, which is time-consuming and labor-intensive, especially for large-diameter logs (such as 30-50cm in diameter), where safety hazards are prominent. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a horizontal hydraulic log splitter with traction function. Through the combined design of "traction design + large-tonnage hydraulic cylinder + manual valve for precise operation + horizontal compact layout + auxiliary feeding mechanism + torsion shaft dual tires + 4 support legs for stable support + self-contained engine + adjustable log splitting blade", it solves the problems of poor mobility, complicated operation, insufficient stability and difficulty in feeding of existing log splitters, and realizes efficient, safe and flexible log splitting operation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a horizontal hydraulic wood splitter with traction function, including a traction rod, a frame, a drive mechanism, a pusher head, a walking mechanism, a support mechanism, a loading mechanism, and a wood splitting blade mechanism; its innovation lies in: the frame includes a main beam, the front end of which is fixedly connected to the traction rod; an engine seat, an oil tank seat, a valve mounting plate, and a pair of loading frame hinge seats are respectively arranged on the left and right sides of the main beam; the drive mechanism is mounted on the engine seat, oil tank seat, and valve mounting plate; the pusher head is slidably disposed on the main beam and slides through the drive mechanism; the walking mechanism is disposed at the bottom of the frame; the support mechanism is disposed at the four corners of the frame for support; the loading mechanism is hinged to the loading frame hinge seats and performs a flipping motion; the wood splitting blade mechanism is fixedly disposed on the crossbeam and corresponds to the pusher head.

[0007] Furthermore, the drive mechanism includes an engine, a gear pump, a hydraulic tank, a pusher cylinder, a manual valve group, and several oil pipes. The engine drives the gear pump through a coupling, and the gear pump converts the engine power into high-pressure oil, which is delivered to the manual valve group through the oil outlet pipe. The manual valve group controls the cylinder movements of the pusher cylinder, the feeding mechanism, and the wood splitting knife mechanism. The piston rod of the pusher cylinder is fixedly connected to the pusher head.

[0008] Furthermore, the manual valve assembly includes a pusher valve operating lever, a feed valve operating lever, and a lifting valve operating lever.

[0009] Furthermore, the pusher head includes a slide plate and a connecting plate, which form an L-shaped structure and are welded together by connecting ribs to form a pusher head weld. The connecting plate is fixedly connected to the piston rod of the pusher cylinder. An upper guide rail plate is provided at the bottom of the slide plate. A pair of pads are provided on both sides of the bottom of the upper guide rail plate. A lower guide rail plate is provided at the bottom of the pads. A pressure plate is provided at the bottom of the lower guide rail plate. A sliding groove is formed between the pressure plates. The sliding groove slides along the main beam.

[0010] Furthermore, the walking mechanism includes a torsion shaft, with tires fixed at both ends of the torsion shaft via bearing seats. The torsion shaft is an elastic steel structure, and its middle part is rigidly connected to the frame.

[0011] Furthermore, the support mechanism is a hand-cranked support leg.

[0012] Furthermore, the feeding mechanism includes a feeding cylinder and a feeding frame. The feeding frame is hinged to the feeding frame hinge seat via a feeding pin. The feeding cylinder is located at the bottom of the frame, with one end hinged to the frame and the piston rod end of the other end hinged to the feeding frame. The feeding frame has an L-shaped structure and a serrated upper surface.

[0013] Furthermore, the wood-splitting mechanism includes a lifting cylinder, a lifting bending plate, a storage trough, and a wood-splitting blade. The lifting bending plate is hinged to the frame via a pin. The lifting cylinder is located at the bottom of the frame, with one end hinged to the frame and the piston rod end of the other end hinged to the lifting bending plate. The wood-splitting blade is fixedly mounted on the storage trough, with its bottom penetrating the storage trough and having a slotted hole. This slotted hole is hinged to the lifting bending plate via a pin.

[0014] Furthermore, the wood-splitting knife has a cross-shaped structure.

[0015] The beneficial effects of this utility model after adopting the above structure are as follows: Significantly improved mobility and adaptability: With the tow bar at the front end, it can be quickly attached to tractors, pickup trucks and other tractors, enabling the rapid transfer of the whole machine between different work sites. It overcomes the shortcomings of traditional fixed or small mobile log splitters, such as difficulty in transportation and weak adaptability, and is particularly suitable for mobile operations in forests, farms and other fields.

[0016] Independent and simple to operate, with no external dependence: The entire hydraulic system is controlled by a manual valve group, and the operation logic is clear and intuitive. All actions such as pushing, feeding, and lifting can be precisely controlled through the operating lever. This system does not rely on an external power source at all, solving the problem that electric motor-driven systems cannot work in the field when there is no power, power outage, or unstable voltage, greatly expanding the applicable scenarios.

[0017] With its powerful chopping ability and high operating efficiency, this product utilizes a large-tonnage hydraulic cylinder to provide tremendous chopping force, easily handling hard logs with diameters ranging from 30 cm to 80 cm. Combined with an adjustable wood-splitting blade, it can quickly adapt to wood of different diameters, increasing chopping efficiency by 5-10 times compared to manual labor, resulting in significant economic benefits.

[0018] The machine boasts exceptional stability and reliable operation: it innovatively employs a composite stabilizing structure of "torsion shaft dual-tire support + four-corner hand-cranked support legs." During transport, the elastic torsion shaft effectively cushions road impacts; during operation, the four support legs provide primary support, with tires providing additional assistance, creating a stable structure with a low center of gravity and a large support surface. This completely eliminates equipment swaying and shifting during heavy-duty chopping, greatly improving operational safety and chopping accuracy.

[0019] Effortless and safe loading, reducing labor intensity: With a hydraulically driven loading mechanism, operators only need to roll the logs to the front of the loading rack. Then, by operating the loading valve lever, the hydraulic cylinder automatically lifts the logs and sends them to the splitting station. This avoids the high-intensity labor and safety hazards of manually lifting heavy, large-diameter logs, achieving semi-automated loading.

[0020] The power system is redundant and reliable with strong environmental adaptability: It is equipped with a self-powered engine and designed with a dual starting mode of "electric start + manual rope start", which ensures that it can still start reliably in harsh environments such as low temperature and insufficient battery power, thus ensuring the continuity and reliability of operation.

[0021] Compact structure and easy maintenance: Utilizing a horizontal layout and integrated design, the engine, hydraulic pump, oil tank, valve assembly, and other components are highly integrated within or above the frame, resulting in a compact overall structure and optimized dimensions, facilitating transportation and operation in confined spaces. Simultaneously, the modular design facilitates routine maintenance and troubleshooting, making it suitable for long-term outdoor use. Attached Figure Description

An engine seat 22, an oil tank seat 23, a valve mounting plate 24, and a pair of loading frame hinge seats 25 are respectively arranged on the left and right sides of the main beam 2. The drive mechanism 3 is installed on the engine seat 22, the oil tank seat 23, and the valve mounting plate 24. The pusher head 4 is slidably arranged on the main beam 21 and slides through the drive mechanism 3. The traveling mechanism 5 is arranged at the bottom of the frame 2.

[0027] The drive mechanism 3 includes an engine 31, a gear pump 32, a hydraulic oil tank 33, a pusher cylinder 34, a manual valve group 35, and several oil pipes. The engine 31 drives the gear pump 32 through a coupling. The gear pump 32 converts the engine power into high-pressure oil, which is delivered to the manual valve group 35 through the oil outlet pipe. The manual valve group 35 controls the cylinder movements of the pusher cylinder 34, the feeding mechanism, and the wood splitting knife mechanism. The piston rod of the pusher cylinder 34 is fixedly connected to the pusher head 4. It is equipped with a small engine that drives the gear pump through a coupling; it is equipped with an electric starter motor, while retaining manual rope start, adapting to low temperature or battery depletion environments; the gear pump converts the engine power into high-pressure oil, which is delivered to the manual valve group through the oil outlet pipe. The operation of each cylinder is controlled by an operating lever, making operation simple and convenient; the pusher cylinder 34 uses a large-tonnage cylinder to provide strong pressure, and with the liftable wood splitting knife, it can handle large-diameter hardwood (efficiency is 5-10 times higher than manual splitting).

[0028] The manual valve assembly 35 includes a pusher valve operating lever, a feed valve operating lever, and a lifting valve operating lever. The oil flow direction is precisely controlled via the operating levers. Operation is simple (no electricity required), making it suitable for outdoor environments without power. The pusher valve operating lever controls the pusher cylinder 34; the feed valve operating lever controls the feed cylinder 71; and the lifting valve operating lever controls the lifting cylinder 81.

[0029] The pusher head 4 includes a slide plate 41 and a connecting plate 42, which form an L-shaped structure and are welded together by connecting ribs 43 to form a pusher head weld. The connecting plate 41 is fixedly connected to the piston rod of the pusher cylinder 34. An upper guide plate 44 is provided at the bottom of the slide plate 41.

[0030] The walking mechanism 5 includes a torsion shaft 5. Tires 52 are fixed to both ends of the torsion shaft 5 via bearing seats. The torsion shaft 51 is a flexible steel structure, and its middle part is rigidly connected to the frame 2. The two tires are connected to the bottom of the frame via a torsion shaft. The torsion shaft is a flexible steel structure, which can buffer the impact force during traction and chopping (reducing machine vibration).

[0031] The support mechanism 6 is a hand-cranked support leg, which is convenient for operation.

[0032] The feeding mechanism 7 includes a feeding cylinder 71 and a feeding frame 72. The feeding frame 72 is hinged to the feeding frame hinge seat 25 through a feeding pin 73. The feeding cylinder 71 is located at the bottom of the frame, with one end hinged to the frame 2 and the piston rod end of the other end hinged to the feeding frame 72. The feeding frame 72 has an L-shaped structure and a serrated upper surface.

[0033] The wood splitting mechanism 8 includes a lifting cylinder 81, a lifting bend plate 82, a storage trough 83, and a wood splitting blade 84. The lifting bend plate 82 is hinged to the frame 2 via a pin. The lifting cylinder 81 is located at the bottom of the frame, with one end hinged to the frame and the piston rod at the other end hinged to the lifting bend plate 82. The wood splitting blade 84 is fixedly mounted on the storage trough 83, with its bottom penetrating the trough and having a slotted hole. This slotted hole is hinged to the lifting bend plate 82 via a pin. The wood splitting blade 84 is raised and lowered by the lifting cylinder 81 and the lifting bend plate 82. It rises to the required height to split large-diameter logs and descends to the required height to split small-diameter logs. In the neutral position, the lifting cylinder (wood splitting blade) locks.

[0034] The wood splitter 84 has a cross-shaped structure and is suitable for splitting round logs and harder wood into the required block shapes.

[0035] The specific details of this application are as follows: (1) Overall layout: The machine adopts a horizontal frame structure (the frame is arranged horizontally), and is connected to the tractor / tractor vehicle through the front traction frame, which facilitates quick transfer of the work site; a torsion shaft double tire support system is set under the frame to ensure stability and reliability during transportation; the frame is equipped with 4 hand-cranked support legs, which support the whole machine during the splitting operation, and the tires play an auxiliary support role, so the machine body will not sway during the splitting operation; the wood splitting blade is vertically arranged in the middle left of the frame; the pusher head and pusher cylinder are horizontally installed on the upper right side of the frame, and the piston rod of the pusher cylinder extends to drive the pusher head forward and cooperate with the wood splitting blade to complete the splitting action of the log section.

[0036] (2) Large-tonnage pusher cylinder: The pusher head is controlled by a large-tonnage pusher cylinder (the pusher head is installed on the main beam and limited by the upper and lower guide plates). It has a large rated thrust and is used to provide strong chopping pressure, which can easily split hardwood (such as oak and pine) with a diameter of 30-80cm.

[0037] (3) Configure a manual valve group to control the flow of hydraulic oil via an operating lever: 1) Push valve operating lever: Move the push valve operating lever to the left → hydraulic oil enters the rodless chamber of the push cylinder → the push head moves forward to split the log section; Move the push valve operating lever to the right → hydraulic oil enters the rod chamber of the push cylinder → the push head moves backward to reset; Neutral position → push cylinder (push head) locks.

[0038] 2) Feeding valve operating lever: Move the feeding valve operating lever to the left → hydraulic oil enters the rodless chamber of the feeding cylinder → the piston rod of the feeding cylinder extends, driving the feeding frame to rotate around the pin of the feeding frame and feed the log section into the trough (the groove between the pusher head and the splitting knife); Move the feeding valve operating lever to the right → hydraulic oil enters the rod chamber of the feeding cylinder → the piston rod of the feeding cylinder retracts, driving the feeding frame to reset; Neutral position → the feeding cylinder (feeding frame) locks.

[0039] 3) Lifting valve operating lever: Move the lifting valve operating lever to the left → hydraulic oil enters the rodless chamber of the lifting cylinder → the piston rod of the lifting cylinder extends and pushes the lifting bending plate to rotate around the pin shaft, causing the wood splitter to rise to the required height (used to split large-diameter logs); Move the lifting valve operating lever to the right → hydraulic oil enters the rod chamber of the lifting cylinder → the wood splitter descends to the required height (used to split small-diameter logs); Neutral position → the lifting cylinder (wood splitter) locks.

[0040] The manual valve is located on the upper part of the pusher cylinder on the frame. It is easy to operate (no electricity required) and is suitable for outdoor environments without power.

[0041] (4) Horizontal frame and compact design: The machine's external dimensions are compacted according to actual needs, making it easy for a tractor to tow it through forest paths or narrow spaces. The hydraulic pump, oil tank, and valve group are integrated inside the frame to reduce space occupation.

[0042] (5) Loading mechanism: The loading frame is hinged to the left front end (or left rear end) of the frame using a loading frame pin. The logs can be moved to the front and below the loading frame by manual pushing or a small forklift, and then pushed onto the loading frame by manual pushing.

[0043] (6) Walking mechanism: The two tires on the left and right are connected by a torsion shaft under the frame. The torsion shaft is an elastic steel structure that can buffer the impact force during traction and chopping (reduce the vibration of the machine body). The middle part of the torsion shaft is rigidly connected to the frame, and the tires are fixed at both ends by bearing seats to ensure that the machine body does not deviate or overturn during chopping.

[0044] (7) Engine electric start system: Equipped with a small diesel engine (or gasoline engine) that drives the gear pump through a coupling; the engine is equipped with an electric start motor (powered by a 12V battery) while retaining manual pull rope start to adapt to low temperature or battery depletion environments; the gear pump converts the engine power into high-pressure oil, which is delivered to the manual valve group through the oil outlet pipe and then drives each cylinder to move.

[0045] Work process: (1) The tractor connects to the log splitter via the towing frame and moves to the work site, then raises the four support legs (the tires only serve an auxiliary purpose); (2) Start the engine (electric start or pull rope), and the hydraulic pump starts working; (3) The operator moves the loading control lever to the left to push the log section through the loading frame between the log splitter and the pusher head; (4) Move the pusher valve control lever to the left → the pusher cylinder drives the pusher head to push the log section forward to the log splitter until the log section is split; after splitting, move the pusher valve control lever to the left → the pusher head resets. Repeat this cycle to complete the log splitting operation.

[0046] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
