DETAILED DESCRIPTION

[0018] 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.

[0019] Example 1.

[0020] like Figure 1-3 As shown, the tow bar assembly for a wood splitter described in this embodiment includes a towing nose 1, a support rod 2 is fixedly installed at the rear end of the towing nose 1, and a hand-cranked support leg 4, a fixed support leg 5 and a tow bar mounting portion 6 are provided on the support rod 2. The hand-cranked support leg 4, the fixed support leg 5 and the tow bar mounting portion 6 are installed on the support rod 2 at intervals along the length direction of the towing nose 1, a universal wheel 7 is installed at the bottom of the hand-cranked support leg 4, and the supporting lengths of the hand-cranked support leg 4 and the fixed support leg 5 relative to the support rod 2 are adjustable, and the tow bar mounting portion 6 is located on the side away from the towing nose 1, and is used to connect to the wood splitter body.

[0021] When working, Figure 2 As shown, the tow bar mounting portion 6 is fixedly installed at the front end of the wood splitter, ensuring a firm and reliable connection between the traction nose 1 and the wood splitter body. At the same time, before starting the wood splitting operation, the operator needs to appropriately adjust the positions of the hand-cranked support legs 4 and the fixed support legs 5 according to the specific conditions of the work site to ensure that the tow bar assembly can provide solid support. The split design of the hand-cranked support legs 4 and the fixed support legs 5 on the support rod 2 allows the user to flexibly select the hand-cranked support legs 4 and the fixed support legs 5 for support according to ground conditions, and the bottom of the hand-cranked support legs 4 is equipped with universal wheels 7, which enables it to move freely on uneven ground, providing flexible support and travel capabilities for the wood splitter, that is, whether it is adjusting the working position of the wood splitter or connecting the traction nose 1 to the traction equipment, the universal wheels 7 can ensure that the wood splitter body is smoothly transitioned and efficiently moved.

[0022] On the other hand, the design of the fixed support leg 5 allows the support length relative to the support rod 2 to be adjusted. This feature allows the user to easily switch to the fixed support leg 5 when a situation requiring more stable support is encountered (such as during wood splitting operations) to ensure the stability and safety of the operation.

[0023] Specifically, if Figure 2 As shown, in order to ensure the flexibility of height adjustment, the fixed support leg 5 is provided with a plurality of pin holes 51 spaced apart along its length direction, and the support rod 2 is provided with a latch 21 matching with the pin hole 51 , and the latch 21 passes through the pin hole 51 to fix the fixed support leg 5 .

[0024] In this way, since the pin holes 51 are spaced apart along the length direction of the fixed support leg 5, a variety of installation position options are provided for the fixed support leg 5, so that it can adapt to various ground conditions and operation requirements. In actual operation, the user can select the appropriate position of the pin hole 51 according to the specific situation, and then insert the pin 21 into the corresponding pin hole to firmly fix the fixed support leg 5 to provide a stable supporting force, ensuring that the wood splitter remains stable during operation. When the wood splitter needs to be towed by the towing nose 1, the user can choose to insert the pin into the upper pin hole 51 to make the fixed support leg 5 suspended. Such adjustment not only retains the installation of the fixed support leg, but also provides convenience for movement under different operating conditions, enhancing the adaptability and practicality of the tow bar assembly.

[0025] In some embodiments, Figure 2 As shown, in order to improve the connection strength, the support rod 2 is provided with a square sleeve 22 adapted to the radial cross section of the fixed leg 5, and the pin hole 51 is set through the square sleeve 22. With this structural design, the square sleeve 22 tightly surrounds the pin hole 51 area of ​​the fixed leg 5, limiting the swing and deflection of the fixed leg 5 after being fixed, so as to ensure that the fixed leg 5 remains vertical and stable when subjected to force, thereby improving the accuracy and safety of the operation.

[0026] In some embodiments, Figure 2 As shown, in order to increase the connection height and enhance the adaptability to operations, the tow rod mounting portion 6 includes a transition diagonal rod 61 and a connecting cross rod 62. The connecting cross rod 62 is connected to the tail of the support rod 2 through the transition diagonal rod 61. The plane where the connecting cross rod 62 is located is higher than the plane where the support rod 2 is located, and a screw hole mounting plate 63 is welded on the connecting cross rod 62.

[0027] Utilizing this structural design, the connecting cross bar 62 is connected via the transition diagonal bar 61, so that the connecting cross bar 62 is located at a position higher than the plane where the supporting rod 2 is located. This design helps to increase the height of the connection point between the wood splitter and the tow bar assembly, so that the wood splitter has better passability during operation, especially when crossing obstacles or operating on uneven ground, it can reduce the operating obstacles caused by uneven ground. At the same time, the screw hole mounting plate 63 welded on the connecting cross bar 62 provides a stable connection interface, which is convenient for fixing the wood splitter body or other accessories in the appropriate position, which is simple and intuitive.

[0028] In some embodiments, Figure 2 As shown, in order to enhance the structural stability, the support rod 2 is a Y-shaped welded part formed by welding a main square tube 2a and two secondary square tubes 2b, and a fastening cover 8 is fixedly installed at the connection transition between the main square tube 2a and the secondary square tube 2b, and the fastening cover 8 is provided with a base 81 for installing the hand-cranked support leg 4.

[0029] In this embodiment, the Y-shaped support rod 2 can disperse and withstand the impact force and pressure generated by the wood splitter during operation, compared with the single-tube structure, thereby improving the stability of the overall structure. At the same time, welding, as an economical and durable method for connecting metal pipes, not only ensures the strength of the structure, but also reduces the manufacturing cost. The fastening cover 8 is installed at the connection transition between the main square tube 2a and the secondary square tube 2b, which can provide additional protection and reinforcement for the welding point and help prevent cracks and fatigue of the welding point due to long-term use or heavy-load operation. In addition, the base 81 on the fastening cover 8 provides a stable and sturdy mounting point for the hand-cranked support leg 4. When necessary, the fastening cover 8 can be quickly accessed and replaced or necessary maintenance can be performed on the hand-cranked support leg 4.

[0030] In some embodiments, Figure 1 and Figure 2 As shown, in order to enhance the support stability, the fixed support leg 5 is installed between the two secondary square tubes 2b. With this structural design, the fixed support leg 5 is installed between the two secondary square tubes 2b to form a more stable support structure. This layout effectively disperses the force acting on the fixed support leg 5, reduces the stress concentration of the unilateral force, and thus improves the stability of the overall structure.

[0031] In some embodiments, Figure 2 As shown, in order to ensure the reliability of the connection, the main square tube 2a is fixedly connected to the traction nose 1 by bolts, and a safety chain 9 is provided on the main square tube 2a. In this embodiment, in addition to the bolt connection, the safety chain 9 provided on the main square tube 2a provides additional safety for the connection. Even if the bolts are loosened in extreme cases, the safety chain can prevent the traction nose 1 from being completely separated from the main square tube 2a, thereby ensuring the safety of the operation.

[0032] In some embodiments, Figure 2 As shown, in order to adapt to different working requirements and conditions, the front end of the support rod 2 is fixedly installed with a multi-hole adjustment plate 10, and the traction nose 1 is fixedly connected to the multi-hole adjustment plate 10 by bolts. In this way, the multi-hole adjustment plate 10 provides a plurality of bolt installation holes, which allows the user to select a suitable hole position to fix the traction nose 1 according to specific working requirements and conditions, so that the traction angle of the towing rod assembly can be adjusted according to different traction equipment to adapt to different wood splitter models and working environments.

[0033] The tow bar assembly for the wood splitter provided in this embodiment, through structural design, the universal wheels of the hand-cranked support legs and the adjustable support length, enable the tow bar assembly to easily cope with various terrains and working conditions, thereby ensuring the stability and operating efficiency of the wood splitter. The Y-shaped support rod structure of the assembly, combined with the reinforcement of the fastening cover, significantly enhances the overall structural stability and load-bearing capacity, thereby improving the wood splitting accuracy and machine durability. In addition, the pin hole and latch design of the fixed support legs and the application of a multi-hole adjustment plate provide users with fast and flexible adjustment performance, thereby optimizing the installation and operation process of the wood splitter.
