[0032] 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.

[0033] 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.

[0034] This embodiment mainly describes a vertical log splitter that improves flexibility and stability during hauling, as detailed below:

[0035] like Figures 1-7 As shown, the vertical log splitter, which is easy to tow, includes a body frame 1 and a rotating frame 2. A tow bar 3 and two wheels 4 are mounted on the body. The tow bar 3 has ground-contacting support feet 5. The rotating frame 2 is rotatably connected to the body frame 1. A guard plate 6 and a worktable 7 are fixed on the rotating frame 2. A hydraulic cylinder 8 is slidably mounted on the rotating frame 2. The hydraulic cylinder 8 includes a telescopically adjustable cylinder barrel 8a and a piston rod 8b. The rotating frame 2 has a slide rail 2a, and a splitter is fixedly mounted on the piston rod 8b. The blade 9 is connected to a slide 10, which is slidably connected to a slide rail 2a. A U-shaped frame 11 is provided on the rotating frame 2. A lug 8c that can slide into the U-shaped frame 11 is provided on the cylinder 8a. A limiting member 12 is detachably installed on the U-shaped frame 11. The limiting member 12 can restrict the cylinder 8a of the hydraulic cylinder 8 from sliding relative to the rotating frame 2. A positioning member 13 is detachably installed on the slide 10. The positioning member 13 can restrict the piston rod 8b of the hydraulic cylinder 8 from sliding relative to the rotating frame 2.

[0036] Preferably, the opening of the U-shaped frame 11 faces the direction of the worktable 7. To facilitate the sliding of the lug 8c into the U-shaped frame 11, both ends of the U-shaped frame 11 can be made into open or outward-facing flared openings.

[0037] In this embodiment, the rotating frame 2 is provided with a fixing hole 2b, and the slide 10 is provided with a fixing hole 10a. When the slide 10 slides along the slide 2a until the fixing hole 2b and the fixing hole 10a are aligned, the positioning member 13 can be inserted into the fixing hole 2b and the fixing hole 10a for installation, thus restricting the slide 10, i.e. the chopping knife 9 or the piston rod 8b, from sliding relative to the rotating frame 2.

[0038] The traction rod 3 of the body bracket 1 is also provided with a support rod 14. A locking shaft 15 is rotatably installed on the support rod 14. A limiting member 16 is threadedly connected to the locking shaft 15. The rotating frame 2 is provided with a U-shaped piece 17. The limiting member 16 is provided with a limiting part 16a. When the rotating frame 2 rotates to a horizontal or oblique position relative to the ground, the U-shaped piece 17 is located between the limiting part 16a and the support rod 14. The limiting member 16 can restrict the rotation of the rotating frame 2 relative to the body bracket 1.

[0039] In this embodiment, the wood splitter has a working state and a towing state.

[0040] Working status: such as Figures 1-5 As shown, the rotating frame 2 is vertically positioned relative to the ground, and the worktable 7 is in contact with or close to the ground. At this time, the opening of the U-shaped frame 11 faces downward, the lug 8c on the cylinder 8a of the hydraulic cylinder 8 is located in the U-shaped frame 11, and the limiting member 12 is inserted into the U-shaped frame 11 to restrict the cylinder 8a of the hydraulic cylinder 8 from sliding down. Through the operation of the hydraulic cylinder 8, the piston rod 8b can be extended and retracted relative to the cylinder 8a.

[0041] To prevent the limiting component 12 from detaching from the U-shaped frame 11 due to vibration during operation, an R-pin 18 is detachably installed on the limiting component 12. The R-pin 18 can prevent the limiting component 12 from detaching from the U-shaped frame 11.

[0042] Meanwhile, to prevent the hydraulic cylinder 8 from shaking or rotating with the lug 8c as a reference when it is working, a support frame 19 is fixed on the rotating frame 2, and a U-shaped hoop 20 is installed on the support frame 19. A limiting cavity is formed between the hoop 20 and the support frame 19, and the cylinder barrel 8a is located in the limiting cavity. The limiting cavity can restrict the rotation or shaking of the cylinder barrel 8a. Preferably, the hoop 20 can be adjusted relative to the support frame 19 by means of nuts and other accessories to adjust the tightness of the clamping of the cylinder barrel 8a between the hoop 20 and the support frame 19.

[0043] Shipping status: such as Figures 6-7 As shown, the rotating frame 2 is arranged horizontally or obliquely relative to the ground. The U-shaped piece 17 on the rotating frame 2 is located between the limiting part 16a and the support rod 14. The limiting part 16 restricts the rotation of the rotating frame 2 relative to the machine body bracket 1. The positioning part 13 is simultaneously inserted into the fixing hole 2b on the rotating frame 2 and the fixing hole 10a on the slide 10. The cylinder barrel 8a and piston rod 8b of the oil cylinder 8 are in a retracted state.

[0044] In order to avoid the fixed hole one 2b and the fixed hole two 10a of the positioning piece 13, the B-shaped pin shaft 21 is inserted into the positioning piece 13, and the B-shaped pin shaft 21 can be detachably inserted into the positioning piece 13.

[0045] In the application, through the rotation setting of the rotating frame 2 and the telescopic adjustable setting of the oil cylinder 8 on the rotating frame 2, when the wood splitting machine is transported, the rotating frame 2 can be transversely arranged relative to the machine body bracket 1, and the cylinder barrel 8a of the oil cylinder 8 can slide towards the workbench 7, so that the wood splitting machine is transported in the state that the oil cylinder 8 is in the contraction state, and the length of the traction rod 3 can be effectively shortened, so that the flexibility and stability of the wood splitting machine during transportation are improved.

[0046] In the embodiment, when the wood splitting machine is switched from the working state to the transportation state, the specific operation steps are as follows:

[0047] Step one: rotate the vertically arranged rotating frame 2 to be transversely or obliquely arranged, so that the U-shaped piece 17 on the rotating frame 2 is attached to or close to the supporting rod 14, and rotate the limiting piece 16 around the shaft 15, so that the limiting part 16a on the limiting piece 16 is above the U-shaped piece 17, and rotate the limiting piece 16 around the threaded shaft, so that the limiting part 16a on the limiting piece 16 is attached to the U-shaped piece 17, and the rotation of the rotating frame 2 is limited.

[0048] Step two: drive the oil cylinder 8 to extend, so that the piston rod 8b on the oil cylinder 8 drives the sliding frame 10 to slide on the slide 2a, until the fixed hole two 10a on the sliding frame 10 is aligned with the fixed hole one 2b on the rotating frame 2, the positioning piece 13 is inserted, the extension of the piston rod 8b is limited, at this time, the limiting piece 12 on the U-shaped frame 11 is removed, when the oil cylinder 8 is in the contraction state, the cylinder barrel 8a of the oil cylinder 8 slides relative to the rotating frame 2, and the lug 8c on the cylinder barrel 8a slides out of the U-shaped frame 11, until the length required for the contraction of the oil cylinder 8, and the work of the oil cylinder 8 is stopped.

[0049] Preferably, the operation of step one and step two can be sequentially interchanged, and after the completion of step one and step two, the wood splitting machine can be transported.

[0050] In the description of the utility model, it should be explained that the terms "upper", "lower", "front", "rear", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the utility model product is used, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation on the utility model.
