DETAILED DESCRIPTION
[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0022] Example 1.
[0023] like Figure 1-7 As shown, the wood splitter with a lifting device described in this embodiment includes a machine body 1, and a power device 2, an oil circuit control device 3, a wood splitting component 4 and a lifting component 5, all of which are arranged on the machine body 1, wherein: Figure 1 The overall structure of the wood splitter is shown. The power unit 2 includes components such as an engine, a gear pump, and a coupling, which serve as a power source for driving the entire wood splitter, while the oil circuit control device 3 is composed of components such as a two-way control valve, an oil pipe, and a lifting handle, which are used to control the splitting action of the wood splitting component 4 and the lifting action of the lifting component 5.
[0024] Specifically, the lifting assembly 5 includes a lifting bracket 51, a lifting cylinder 52 and a lifting arm 53. The body 1 is provided with a bracket mounting ear 11 and a cylinder mounting ear 12. The bracket mounting ear 11 is provided with two first fixed cylinders 13. The lifting bracket 51 is provided with two second fixed cylinders 54 that rotate with the first fixed cylinders 13. The lifting cylinder 52 is connected to the cylinder mounting ear 12 through a hinge; one end of the lifting arm 53 is connected to the power output end of the lifting cylinder 52 through a hinge, and the other end is provided with a third fixed cylinder 55 that rotates with the first fixed cylinder 13, and the end of the lifting arm 53 that cooperates with the lifting cylinder 52 is against the bottom surface of the lifting bracket 51.
[0025] In actual use, the user rolls the wood onto the lifting bracket 51 and operates the lifting handle. The oil circuit control device 3 then controls the lifting cylinder 52 to extend. As the lifting cylinder 52 extends, the lifting arm 53 rotates around the machine body 1 through the third fixed cylinder 55. Since the movable end of the lifting arm 53 is against the bottom surface of the lifting bracket 51, the rotation of the lifting arm 53 drives the lifting bracket 51 to rotate relative to the third fixed cylinder 55 through the second fixed cylinder 54, thereby realizing automatic lifting of the wood; when the wood is lifted to the working surface of the wood splitter, the lifting cylinder 52 stops extending. At this time, the user operates the oil circuit control device 3 to control the wood splitting component 4 to split the wood according to the preset action path. After the wood splitting is completed, the user operates the oil circuit control device 3 again to control the lifting cylinder 52 to retract. As the lifting arm 53 descends, the wood is gradually lowered to the working surface or designated position of the machine body 1.
[0026] In this way, through the coordinated action of the lifting bracket 51, the lifting cylinder 52 and the lifting arm 53, the wood can be automatically lifted onto the working surface of the wood splitter, effectively reducing the labor intensity of the operator. At the same time, the wood splitter has a compact structure, relatively low cost, good mobility and wide applicability, and is very suitable for use in various scenarios such as homes, construction sites, and forest farms.
[0027] In some embodiments, Figure 1 , Figure 5 and Figure 6 As shown, for the sake of mobility and ease of operation, the body 1 is also provided with traveling wheels 6 and a tow bar 7, as well as a support leg 8 that can be unfolded or folded relative to the body 1, a fixed hook 81 is provided on one side of the support leg 8, and a hanging ear 16 that cooperates with the fixed hook 81 is provided on the body 1, and the hanging ear 16 cooperates with the hook 81 to limit the support leg 8 to remain in a folded state.
[0028] In this embodiment, the wood splitter is equipped with traveling wheels 6, which give the device mobility. When the wood splitter needs to be moved, the user can use the tow bar 7 to tow the machine to the designated work location, whether it is a flat concrete ground or a rugged woodland. After arriving at the work location, the user can unfold the support legs 8 according to the ground conditions to provide additional stability. The design of the support legs 8 allows them to be quickly unfolded or folded when needed. For example, when moving the wood splitter, the support legs 8 can be folded up, and the fixed hooks 81 on one side of the support legs 8 can be used to cooperate with the hanging ears 16 on the body 1, so as to prevent the support legs 8 from hitting the body 1 during movement, reduce accidental risks, and improve the safety of operation.
[0029] In some embodiments, Figure 2 , Figure 3 and Figure 5As shown, for the convenience of storage and transportation, a first fixing ear 56 is fixedly installed on the second fixing cylinder 54, and a first latch 57 is passed through the first fixing ear 56. A first socket 111 adapted to the first latch 57 is opened on the bracket mounting ear 11, and the first fixing ear 56 is configured to rotate synchronously with the lifting bracket 51. When the lifting bracket 51 is rotated to a vertical state relative to the body 1, the first latch 57 is coaxial with the first socket 111.
[0030] Utilizing this structural design, the first fixing ear 56 is designed to rotate synchronously with the lifting bracket 51, ensuring that when the lifting bracket 51 needs to be fixed in a specific position (generally a vertical state), the first latch 57 can be accurately inserted into the first plug hole 111, that is, after the operation is completed or the wood splitter is being transported, the lifting bracket 51 can be freely rotated to a vertical state, and then the first latch 57 can be inserted into the first plug hole 111 to lock the position of the lifting bracket 51 into a state suitable for storage and transportation. This not only optimizes the storage space of the wood splitter, but also significantly improves the efficiency and convenience of transportation.
[0031] In some embodiments, Figure 2 , Figure 3 and Figure 4 As shown, in order to simplify the mechanical structure, the first fixed cylinder 13, the second fixed cylinder 54 and the third fixed cylinder 55 are coaxially penetrated by the rotating shaft 10. In this way, by adopting the rotating shaft 10, the three key fixed cylinders (13, 54, 55) can be accurately aligned and connected in series to form a compact and efficient structure. This design reduces the dependence on additional connecting parts, thereby simplifying the mechanical structure. At the same time, this integrated configuration enhances the overall rigidity and stability of the wood splitter, so that it can more effectively resist the mechanical stress caused by repeated operations.
[0032] In some embodiments, Figure 4 , Figure 5 and Figure 6 As shown, in order to improve the safety of operation, it also includes a material stopping frame 9, which is installed at the front end of the body 1 through a hinge structure, and the body 1 is provided with a second fixing ear 14, and the material stopping frame 9 is provided with a second plug hole 91, and a second pin 92 is inserted into the second plug hole 91. When the material stopping frame 9 is rotated to a vertical state relative to the body 1, the second pin 92 passes through the second fixing ear 14 and is placed in the second plug hole 91.
[0033] With this structural design, as the wood splitting assembly 4 performs the chopping action, the wood is effectively split, and the chopped wood is then firmly caught by the rear material stopper 9. This process not only prevents the possible operational risks caused by the wood rolling or moving out of the working area, but also ensures the cleanliness and orderliness of the working area, helping to maintain a clean and safe working environment.
[0034] In addition, when the operation is completed or the wood splitter needs to be transported, the material blocking frame 9 can be flexibly rotated to a vertical state like the lifting bracket 51, and locked through the coordinated cooperation of the second pin 92, the second fixing ear 14 and the second socket 91, so that the material blocking frame 9 can be firmly maintained in a vertical position, which greatly improves the portability of the wood splitter and further enhances its adaptability in different working scenarios.
[0035] In some embodiments, Figure 1 As shown, in order to reduce vibration and impact of the material stopper 9, a shock absorbing pad 15 is installed on the second fixing ear 14. In this embodiment, when the material stopper 9 is retracted, the shock absorbing pad 15 helps to reduce the impact caused by the contact between the material stopper 9 and the machine body or other parts, thereby protecting the mechanical structure from damage.
[0036] In some embodiments, Figure 1 and Figure 7 As shown, in order to optimize the wood chip extraction, the wood splitting assembly 4 includes a wood splitting cylinder 41 and an axe 42, the wood splitting cylinder 41 is connected to the oil circuit control device 3, and is arranged opposite to the axe 42, the material blocking frame 9 is arranged on the side of the axe 42, and the power output end of the wood splitting cylinder 41 is fixedly connected with a push plate 43, and a chip removal plate 44 is provided at the bottom of the push plate 43, the plate surface of the chip removal plate 44 is in contact with the working surface of the machine body 1, and guide rails 45 matching the chip removal plate 44 are provided on both sides of the working surface of the machine body 1, and the side edges of the guide rails 45 are provided with limited position edges 46.
[0037] With this structural design, the wood splitting cylinder 41 is connected to the oil circuit control device 3, ensuring the power supply for the wood splitting action, and is arranged opposite to the axe 42 to perform the wood splitting operation. The material blocking frame 9 is located on the peripheral side of the axe 42, which is used to accurately catch the wood. The push plate 43 is provided with anti-slip grooves on the side opposite to the axe 42, so as to stably push the wood forward during the wood splitting process, ensuring the contact between the wood and the axe 42 and the splitting effect.
[0038] In addition, a chip removal plate 44 is provided at the bottom of the push plate 43, and its plate surface is tightly fitted with the work surface of the machine body 1, and the edge of the push plate 43 adopts a bevel design, so that it can form a smooth surface with the work surface of the machine body 1, thereby effectively guiding the smooth discharge of wood chips during the operation of the wood splitting cylinder 41 (the side where the wood splitting cylinder 41 retreats). At the same time, guide rails 45 that cooperate with the chip removal plate 44 are provided on both sides of the work surface of the machine body 1. These guide rails 45 not only guide the discharge direction of the wood chips, but also ensure that the wood on the work surface of the machine body 1 will not shift during the splitting process through the side limiting edges 46.
[0039] The wood splitter with a lifting device provided in this embodiment realizes automatic lifting and splitting of wood by integrating key components such as a power device, an oil circuit control device, a wood splitting assembly and a lifting assembly on the machine body. The design of the lifting assembly can automatically lift the wood onto the bed of the wood splitter, eliminating tedious manual handling actions, greatly saving manual labor, and improving utilization efficiency and operating comfort. At the same time, the wood splitter has a simple structure, a low overall machine cost, and a good service life, which meets the needs of a wide range of users such as families and units, and embodies strong economy and practicality.
