[0002] In recent years, as the core power equipment for agricultural mechanization, the ability of tractors to quickly get out of trouble in complex working environments directly affects operational efficiency and scope of use.
[0003] Currently, the tractor industry's off-road design mainly focuses on optimizing four-wheel drive systems. However, this type of technology has inherent limitations: when vehicles get stuck in extreme conditions such as deep mud or sand, relying solely on a four-wheel drive system is insufficient for effective extrication. A few tractors equipped with traction devices use a fixed connection structure, fixing the traction device to the rear of the vehicle body, making it impossible to disassemble, significantly increasing maintenance time and operational complexity. Utility Model Content

[0009] In some embodiments, the positioning frame includes a second main body plate and a positioning pin, the positioning pin being used for positioning and engaging with the positioning component of the tractor, the positioning pin being disposed at the end of the second main body plate along the width direction of the tractor, and the second main body plate being connected to the mounting plate.
[0010] In some embodiments, the first main body plate is mounted on the upper end of the mounting plate, the second main body plate is mounted on the lower end of the mounting plate, and the first main body plate, the second main body plate, and the mounting plate form a clearance space to avoid the tractor.
[0011] In some embodiments, both the first main body plate and the second main body plate are connected to the mounting plate via an arc transition.
[0012] In some embodiments, the traction assembly is connected to the mounting plate via a plurality of connectors, the plurality of connectors being spaced apart on the mounting plate.
[0013] In some embodiments, the traction assembly includes an integrated housing and a drive member and a winding member mounted on the integrated housing.

[0039] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0040] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.
[0041] In recent years, tractors, as the core power equipment for mechanized agricultural operations, have seen their ability to quickly extricate themselves from difficult working environments directly impacting operational efficiency and scope of use. Currently, the tractor industry's extrication design primarily focuses on optimizing four-wheel drive systems. However, this approach has inherent limitations: when vehicles are stuck in extreme conditions such as deep mud or sand, relying solely on a four-wheel drive system is insufficient for effective extrication. A few tractors equipped with traction devices employ a fixed connection structure, fixing the traction device to the rear of the vehicle. While this can aid in extrication to some extent, this design has significant drawbacks. The fixed connection means the traction device occupies the rear interface of the vehicle for extended periods, and it also makes disassembly difficult during maintenance, significantly increasing maintenance time, costs, and operational complexity.
[0042] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a traction device 3 for a tractor 1. The traction device 3 includes a traction assembly 40 and a mounting assembly 30. The mounting assembly 30 includes a mounting plate 31 and a quick-connect bracket 32 and a positioning bracket 33 connecting the mounting plate 31. The traction assembly 40 is mounted on the mounting plate 31. The quick-connect bracket 32 is provided with a quick-connect hole 323 for quick connection with the tractor 1 via a quick-connect pin. The positioning bracket 33 is used for positioning and engaging with the positioning component 105 of the tractor 1. The traction device 3 can be used to quickly connect the suspension 101 located at the rear of the tractor 1.
[0043] The traction device 3 provided by this utility model achieves quick assembly and disassembly with the tractor 1 through the mounting component 30. The mounting component 30 includes a mounting plate 31, a quick-connect bracket 32, and a positioning bracket 33. The mounting plate 31 is used to install the traction component 40. The positioning bracket 33 is positioned and snapped into the suspension 101 of the tractor 1, thus facilitating the quick-connect bracket 32 after positioning of the traction device, while ensuring installation accuracy. After aligning the quick-connect hole 323 with the hole position on the tractor 1, the quick-connect pin can be used to connect the traction device to the tractor 1 through the quick-connect hole 323 on the quick-connect bracket 32. In this embodiment, the quick-connect bracket 32 of the mounting component 30 only needs to be aligned with the hole position on the tractor 1 to achieve quick connection through the quick-connect pin. No structural modification of the tractor 1 is required. The existing hole position on the tractor 1 can be used. Furthermore, the positioning bracket 23 is equipped with a positioning component adapted to the tractor 1. The initial installation of the traction device can be achieved simply by inserting and snapping into the tractor 1, without requiring any structural modification of the tractor 1. In this embodiment, the traction device, through the cooperation of the traction component 40 and the mounting component 30, enables the quick installation and disassembly of the traction device and the tractor 1 without occupying the interface structure on the tractor, greatly improving the convenience of maintenance.
[0044] In addition, this connection method does not require complicated tools or a lot of time, significantly improving work efficiency, especially in scenarios where agricultural implements are frequently changed; eliminating the complex linkage mechanism results in a compact overall structure, reducing the load on the suspension 101 system and facilitating efficient power transmission from the tractor 1.
[0045] In some embodiments, the quick-connect bracket 32 includes a first main body plate 321 and at least two quick-connect plates 322 disposed on the first main body plate 321. Each quick-connect plate 322 has a quick-connect hole 323 for a quick-connect pin to pass through. The first main body plate 321 is connected to the mounting plate 31. Specifically, in the actual connection process, the suspension 101 of the tractor 1 has a corresponding connection hole 103. The quick-connect pin passes through the quick-connect hole 323 and the quick-connect pin in sequence to realize the connection between the traction device 3 and the tractor 1. Providing at least two quick-connect plates 322 can improve the stability of the connection. Moreover, the connection through the quick-connect pin allows the traction device 3 to swing freely within a certain angle, adapting to uneven terrain or changes in the posture of agricultural implements, and reducing wear or deformation of mechanical parts caused by rigid connection.
[0046] In some embodiments, the positioning frame 33 includes a second main body plate 331 and a positioning pin 332. The positioning pin 332 is used for positioning and engaging with the positioning component 105 of the tractor 1. The positioning pin 332 is located at the end of the second main body plate 331 along the width direction of the tractor 1. The second main body plate 331 is connected to the mounting plate 31. The engagement design between the positioning pin 332 and the positioning component 105 enables rapid alignment of mechanical parts, reduces adjustment time during installation, and is especially suitable for scenarios where agricultural implements are frequently changed, thereby improving work efficiency. The positioning pin 332 located along the width direction can prevent the second main body plate 331 from interfering with the positioning of the positioning pin 332, and can also share the lateral torque generated during tractor 1 traction operations, avoiding structural deformation caused by stress concentration.
[0047] In some embodiments, the first main body plate 321 is mounted on the upper end of the mounting plate 31, and the second main body plate 331 is mounted on the lower end of the mounting plate 31. The first main body plate 321, the second main body plate 331, and the mounting plate 31 form a clearance space to avoid the tractor 1. By reserving clearance space, it is ensured that the components of the tractor 1 will not directly contact the traction device 3 during movement, eliminating wear, deformation, or accidental damage to components caused by friction or collision; avoiding the rigid structure from squeezing the key components of the tractor 1, reducing the risk of failure caused by mechanical interference; when the tractor 1 is operating on rough ground, the suspension 101 system needs to frequently adjust its height and angle. The clearance space provides physical tolerance for the free movement of the suspension 101 mechanism, ensuring that the traction device 3 is always stably connected, while not restricting the dynamic adaptability of the tractor 1.
[0048] In some embodiments, both the first main body plate 321 and the second main body plate 331 are connected to the mounting plate 31 via a rounded transition. That is, the first main body plate 321, the second main body plate 331, and the mounting plate 31 can be connected by welding or other methods to form an integrated structure. Right-angle or sharp-angle connections are prone to stress concentration points, especially under dynamic loads (such as the bumps of a tractor 1 or the impact of agricultural implements), which may lead to weld cracking or fatigue fracture of the plates. The rounded transition disperses stress through smooth curvature, avoiding localized stress peaks, improving fatigue resistance, and extending structural life. Furthermore, the rounded connection eliminates dead angles, reduces debris adhesion, facilitates washing or cleaning, and reduces maintenance frequency.
[0049] In some embodiments, the traction assembly 40 is connected to the mounting plate 31 via multiple connectors 34, which are spaced apart on the mounting plate 31. In practical use, the connectors 34 can be bolts or other components capable of connection. This invention does not impose specific limitations. Using multiple connectors 34 spaced apart can effectively improve the stability of the connection between the traction assembly 40 and the mounting plate 31.
[0050] In some embodiments, the traction assembly 40 includes an integrated housing 41 and a drive member 411 and a winding member 412 mounted on the integrated housing 41. The drive member 411 drives the winding member 412 to rotate and unwind the traction rope on the winding member 412. The integrated housing 41 is provided with an integrated cavity 413, in which the winding member 412 is housed. The drive member 411 is located outside the integrated cavity 413, and the integrated housing is connected to a mounting plate 31. By housing all components within the integrated housing 41, protection of the components is achieved, and the weight of the traction device 3 is reduced. At the same time, by driving the winding member 412 to rotate and unwind the traction rope through the drive member 411 to apply traction force, the traction device 3 is both lightweight and has traction force, enabling efficient towing and escape from difficult situations.
[0051] In some embodiments, the integrated shell 41 includes multiple side plates, which together form an integrated cavity 413 with an opening 414. Specifically, the multiple side plates are a left side plate, a top plate, a right side plate, a bottom plate, and a rear side plate. The left side plate, right side plate, top plate, bottom plate, and rear side plate together form an integrated cavity 413 that is closed on five sides and open on one side 414. When the integrated shell 41 is installed on the mounting bracket 214, the opening 414 faces the hollow portion 24. The traction rope passes through the opening 414 and the hollow portion 24 in sequence and connects to external equipment. At least one guide member 415 is provided at the opening 414 to guide the direction of the traction rope's release and retraction. In this embodiment, two guide members 415 are provided at the opening 414, respectively located on both sides of the opening 414. Providing guide members 415 at the opening 414 can prevent the rope from hard contacting and wearing the opening 414. After the guide member 415 wears out, it can be directly removed and replaced from the opening 414 without opening the main body of the integrated shell 41. The top of the integrated housing 41 is provided with multiple lifting rings 416, which are spaced apart on the edge area of the top of the integrated housing 41. The lifting rings 416 are used for hooking by lifting equipment or manual lifting to transfer the traction assembly 40. The spaced distribution of the lifting rings 416 on the edge area of the top of the integrated housing 41 ensures that the force is evenly distributed when transferring the traction assembly 40, thus avoiding damage to the traction assembly 40.
[0052] The second aspect of this utility model provides a tractor 1, which is connected to the aforementioned traction device 3. A mounting assembly 30 is detachably connected to the suspension 101 of the tractor 1. Specifically, the suspension 101 includes an upper pull rod 102 with a connecting hole 103. The connecting hole 103 is compatible with a quick-connect hole 323 on a quick-connect bracket 32. A quick-connect pin passes through the quick-connect hole 323 and the connecting hole 103 in sequence, thereby connecting the traction device 3 to the tractor 1. Alternatively, the suspension 101 includes a lower pull rod 104 with a positioning element 105. A positioning pin 332 and the positioning element 105 are engaged in a locking and positioning fit, with the positioning pin 332 locked into the positioning element 105, similarly enabling the connection between the traction device 3 and the tractor 1.
[0053] In another embodiment, the suspension 101 includes an upper pull rod 102 with a connecting hole 103. The connecting hole 103 is compatible with a quick-connect hole 323 on the quick-connect bracket 32. A quick-connect pin passes through both the quick-connect hole 323 and the connecting hole 103 to connect the traction device 3 to the tractor 1. Simultaneously, a positioning pin 332 and a positioning element 105 engage in a locking mechanism, with the positioning pin 332 locked into the positioning element 105. The quick-connect hole 323 and the positioning pin 332 together connect the traction device 3 to the tractor 1. The quick-connect pin ensures the connection between the upper pull rod 102 and the traction device 3 and provides high tensile strength. The lower pull rod 104's locking mechanism provides stable support, reduces the risk of loosening during operation, and ensures safety during high-intensity operations.
[0054] This utility model provides a traction device 3 for a tractor 1. The traction device 3 includes a traction component 40 and a mounting component 30. The mounting component 30 includes a mounting plate 31 and a quick-connect bracket 32 and a positioning bracket 33 for connecting the mounting plate 31. The traction component 40 is mounted on the mounting plate 31. The quick-connect bracket 32 is provided with a quick-connect hole 323 for quick connection with the tractor 1 through a quick-connect pin. The positioning bracket 33 is used for positioning and engaging with the positioning component 105 of the tractor 1. The mounting assembly 30 enables quick assembly and disassembly with the tractor 1. The mounting assembly 30 includes a mounting plate 31, a quick-connect bracket 32, and a positioning bracket 33. The mounting plate 31 is used to install the traction assembly 40. The quick-connect bracket 32 is connected to the tractor 1 through the quick-connect hole 323 on the quick-connect plate 322. The positioning bracket 33 is positioned and engaged with the suspension 101 of the tractor 1. This connection method eliminates the need for complex tools or a lot of time, significantly improving work efficiency, especially in scenarios where agricultural implements are frequently changed. It also eliminates the need for complex linkage mechanisms, resulting in a compact overall structure, reducing the load on the suspension 101 system, and facilitating efficient power transmission from the tractor 1.
