Description

Technical Field

[0001] This utility model relates to the field of wood splitting machine technology, and in particular to a hydraulic wood splitter that can be used both vertically and horizontally. Background Technology

[0002] Hydraulic wood splitters are widely used equipment in the forestry and wood processing industries. They use a hydraulic system to drive the splitting blades to split wood, greatly reducing the labor intensity of the operator.

[0003] To accommodate timber of varying sizes and weights, a hydraulic log splitter capable of operating both horizontally and vertically has emerged in the prior art. The main beam of this type of log splitter can switch between a horizontal working position and a vertical working position. The horizontal working mode facilitates the operator's handling of lighter, shorter timbers, while the vertical working mode allows the operator to roll heavy, thick logs directly into position for splitting, eliminating the need to laboriously lift them onto the machine, thus improving operational convenience and applicability.

[0004] However, existing log splitters that integrate both vertical and horizontal operation often neglect the stability and durability of the overall structure under different working conditions while pursuing functional versatility. This is especially true when splitting large-diameter hardwoods in vertical mode, where there is a risk of swaying or even tipping over, posing a safety hazard. Furthermore, existing products also have shortcomings in safety design and the ease of maintenance of the hydraulic system, making it difficult to simultaneously meet the comprehensive requirements of ease of operation, high work efficiency, structural stability, and safety reliability. Utility Model Content

[0005] In view of this, the present invention provides a vertical and horizontal dual-purpose hydraulic wood splitter, which aims to solve the technical problems of insufficient structural stability, safety and maintenance convenience of existing vertical and horizontal dual-purpose wood splitters while taking into account both ease of operation and wood splitting efficiency.

[0006] According to one aspect of this utility model, a vertical and horizontal dual-purpose hydraulic log splitter is provided, comprising: frame; The main beam is pivotally connected to the frame to switch between a horizontal working position and a vertical working position; A locking mechanism is used to selectively lock the main beam in the horizontal working position; The wood-splitting blade is detachably mounted on the main beam; A hydraulic drive device is used to drive the wood splitter head to reciprocate along the length of the main beam; Also includes: The base is fixedly mounted on the end of the main beam away from the wood splitting head. When the main beam is in the vertical working position, the base is used to provide ground support for the wood splitter, and the width of the base is greater than the width of the frame.

[0007] Optionally, the locking mechanism is a pull-in quick-release clamp, which includes a jaw disposed on the main beam and a locking pin that can pass through the jaw and the frame.

[0008] Optionally, the end of the locking pin is provided with a U-shaped bracket with an elastic element.

[0009] Optionally, the wood-splitting blade is a combined blade, which includes a first blade with a V-shaped cross-section and a plate-shaped second blade that can be inserted laterally into the first blade.

[0010] Optionally, the wood-splitting blade is an integrated cross-shaped blade.

[0011] Optionally, the hydraulic system of the hydraulic drive device is equipped with a flange-type oil suction filter at the oil suction port of the hydraulic oil tank.

[0012] Optionally, the front of the frame is provided with a foldable front support leg.

[0013] Optionally, the frame is provided with tires underneath, and the tires are provided with mudguards.

[0014] Optionally, wooden planks are provided on both sides of the main beam; The area of ​​the shelf board closer to the hydraulic drive device is larger than the area of ​​the shelf board farther away from the hydraulic drive device.

[0015] Optionally, the main beam is a tubular beam structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Compared with traditional wood splitters, the wood splitter provided by this utility model has a base wider than the frame. When the wood splitter is in a vertical working state, its supporting base area is greatly increased, which effectively resists the impact force and lateral torque generated when splitting large-diameter hardwood. This fundamentally solves the safety hazards of easy shaking and tipping of equipment in the prior art, and significantly improves the stability and safety of vertical operation.

[0017] Meanwhile, the locking mechanism reliably fixes the main beam in the horizontal working position, ensuring operational stability when handling conventional timber.

[0018] In addition, the detachable design of the wood splitter head and the optimization of the hydraulic system simplify the replacement of vulnerable parts and the daily maintenance process, improving the durability and ease of maintenance of the equipment. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Based on the defects described in the background art, the following section, in conjunction with specific appendices, Figure 1-4 A preferred embodiment of the present invention, a hydraulic log splitter that can be used both vertically and horizontally, is described in detail.

[0024] This utility model provides a preferred embodiment of a hydraulic log splitter that can be used both vertically and horizontally. Please refer to [link / reference]. Figures 1 to 6 The wood splitter mainly includes a frame 10, a main beam 20, a locking mechanism 30, a wood splitting blade 40, a hydraulic drive device 50, and a base 70 as a core improvement.

[0025] The frame 10 forms the load-bearing foundation of the entire log splitter, typically constructed from high-strength steel using welding or bolting to create a robust frame structure. A pair of tires 60 are mounted beneath the frame 10 to facilitate easy movement of the equipment within the work area. A hydraulic drive unit 50 is usually integrated and mounted at one end of the frame 10, providing the power source for log splitting operations.

[0026] The main beam 20 is the primary working platform for wood splitting operations, with one end pivotally connected to the frame 10. This pivotal connection allows the main beam 20 to... Figure 1 The horizontal working position shown is the same as Figure 2 The vertical working position can be switched as shown, thus achieving a dual-purpose function of standing and lying down. In one embodiment of this application, the main beam 20 preferably adopts a tubular beam structure, for example, made of rectangular or square thick-walled steel pipes. This structure can effectively control the overall weight while ensuring sufficient bending and torsional strength. The timber is placed on the main beam 20 during the splitting operation.

[0027] The hydraulic drive unit 50, serving as the power core of the wood splitter, mainly comprises a power unit (such as an electric motor or internal combustion engine), a hydraulic pump, a hydraulic oil tank 51, a control valve assembly, and a hydraulic cylinder 54. The cylinder body of the hydraulic cylinder 54 is fixed to one end of the main beam 20, specifically connected to the main beam 20 via an embedded cylinder plate 53. This embedded method enhances the connection strength. The end of the piston rod of the hydraulic cylinder 54 is connected to the wood splitting blade 40. When the operator activates the hydraulic drive unit 50, the hydraulic pump pressurizes the hydraulic oil in the hydraulic oil tank 51 and delivers it to the hydraulic cylinder 54 through the control valve assembly, thereby driving the piston rod to extend or retract. Correspondingly, the wood splitting blade 40 reciprocates linearly along the length of the main beam 20, applying a significant thrust to the wood placed on the main beam 20 to achieve splitting.

[0028] To improve equipment maintenance convenience and extend its service life, this embodiment optimizes the hydraulic system. Please refer to... Figure 4 A flange-type oil suction filter device 52 is installed at the oil suction port of the hydraulic oil tank 51.

[0029] The flange-type suction oil filter device 52 is connected to the suction line of the hydraulic oil tank 51 via a detachable flange. Compared to traditional built-in or spin-on suction oil filters, the replacement or cleaning process is relatively complex, sometimes even requiring the drainage of some hydraulic oil. With the flange connection, when the filter needs maintenance, the maintenance personnel only need to unscrew the flange connection bolts to easily remove the entire filter device for cleaning or replacement, eliminating the need for complex disassembly operations. This significantly simplifies the maintenance process, shortens downtime, and more effectively ensures the cleanliness of the hydraulic oil, thereby protecting precision components such as the hydraulic pump.

[0030] The wood splitter head 40 is the actuating component that directly interacts with the wood.

[0031] In this embodiment, to adapt to different wood-splitting needs, the wood-splitting blade 40 is designed as a detachable modular structure, which has a blade guard 43 to protect the wood-splitting blade 40.

[0032] Please see Figure 3 The combined wood splitter head 40 includes a main blade body, namely the first blade head 41, with a sharp V-shaped cross-section for initial splitting of wood. Simultaneously, a through slot is formed on the first blade head 41, into which a plate-shaped second blade head 42 can be inserted laterally, forming a cross-splitting structure with the first blade head 41. The second blade head 42 can be installed when it is necessary to split the wood into four pieces at once; it can be easily removed when it is only necessary to split the wood in half. The base of the entire wood splitter head 40 is fixed to the connecting end of the piston rod of the hydraulic cylinder 54 with high-strength bolts, achieving a reliable and convenient detachable connection. This design not only enhances operational flexibility but also makes replacement or resharpening of the blade head after wear more convenient.

[0033] The locking mechanism 30 is used to securely lock the main beam 20 to the frame 10 when the wood splitter is in a horizontal working position, to prevent unnecessary relative displacement or shaking due to force during the wood splitting process. (See also...) Figure 1 and Figure 4 When the main beam 20 is laid flat in the horizontal working position, the locking mechanism 30 comes into play.

[0034] As an alternative implementation, the locking mechanism 30 employs a convenient pull-out quick-release clamp.

[0035] Specifically, one or more grippers 31 are welded and fixed below the main beam 20, away from the pivot point, and the grippers 31 have through holes; corresponding through holes are also provided at the corresponding positions on the frame 10. A locking pin 32 can pass through the through holes of the frame 10 and the grippers 31 in sequence.

[0036] To prevent the locking pin 32 from accidentally slipping out during equipment vibration and to facilitate insertion and removal by the operator, a U-shaped bracket 33 with an elastic element is provided at the end of the locking pin 32. This U-shaped bracket 33 can be a spring-loaded steel clamp. When the locking pin 32 is inserted into place, the U-shaped bracket 33, relying on its own elasticity, clamps against the outside of the gripper 31 or the frame 10, thus reliably locking the locking pin 32 in the working position. When switching to the vertical mode, simply squeeze the U-shaped bracket 33 by hand and pull out the locking pin 32; the operation is very quick.

[0037] It should be noted that an important technical feature of this embodiment is that by setting the base 70, the problem of insufficient stability of the wood splitter in the vertical working mode in the prior art is effectively solved.

[0038] Please see Figures 1 to 6 When dealing with large, heavy wooden stakes, the operator pulls out the locking pin 32 and rotates the main beam 20, along with the wood splitting blade 40 and hydraulic cylinder 54, upwards by 90 degrees, placing it in a vertical working position.

[0039] At this point, the base 70, which is fixedly installed at the end of the main beam 20 away from the wood splitter head 40 (i.e., the original free end), comes into contact with the ground and becomes the main support foundation for the entire wood splitter in vertical mode. This base 70 is usually made of a thick steel plate and is firmly fixed to the end of the main beam 20 by welding.

[0040] The key feature is that the width of the base 70 is designed to be significantly greater than the width of the frame 10 itself. For example, in a specific implementation, if the width of the frame 10 is 800 mm, the width of the base 70 can be designed to be 1200 mm or wider, for example, 1.5 times the width of the frame 10. Accordingly, when the wood splitter is upright, its contact with the ground forms a large supporting base, greatly increasing the machine's anti-tipping moment. When the wood splitter head 40 moves downward to split large-diameter logs with hard texture or knots, the huge impact force and possible lateral force generated are effectively dispersed and absorbed by this large base 70, thereby ensuring the machine has excellent stability and effectively avoiding the risk of swaying or even tipping due to uneven force distribution, significantly improving the safety and reliability of vertical operation.

[0041] The working process of this wood splitter can be summarized as follows: (1) When processing lighter and shorter timber, the operator places the wood splitter in a horizontal working state, inserts the locking pin 32 to engage the locking mechanism 30, and locks the main beam 20.

[0042] (2) Then place the wood in the splitting area of ​​the main beam 20, start the hydraulic drive device 50, and the wood splitting blade 40 moves forward horizontally, splitting the wood and then automatically retracting.

[0043] (3) When dealing with heavy and thick wooden piles, the operator first pulls out the locking pin 32 to release the locking of the main beam 20.

[0044] (4) Then, grasp the end of the main beam 20, lift it upwards and rotate it until the main beam 20 is fully upright and the base 70 lands smoothly on the ground. Since there is no need to lift the heavy log, the operator can directly roll it to the splitting position between the ground and the splitting blade 40. Then, activate the hydraulic drive device 50, and the splitting blade 40 moves vertically downwards under the drive of the hydraulic cylinder 54 to complete the splitting of the log. During this process, the large base 70 provides excellent stability.
