DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0024] Reference Figure 1-4 , which is the first embodiment of the utility model, and provides a double-layer traction for a tractor, including a traction frame 1, a connecting plate 2 is fixedly installed inside the traction frame 1, a through hole 3 is opened on the front of the connecting plate 2, an inner traction rod 4 is fixedly installed in the inner cavity of the through hole 3, an outer traction rod 5 is fixedly installed at the end of the inner traction rod 4, and the outer traction rod 5 is rotatably connected to the inner traction rod 4 through a connecting piece 6, and an arc plate 14 is fixedly installed on the top of the traction frame 1, and a limiting hole 15 is opened on the top of the arc plate 14.

[0025] Specifically, the connecting member 6 includes a first threaded connecting tube 601, a connecting rod 602, a U-shaped plate 603, a connecting hole 604 and a second threaded connecting tube 605. The first threaded connecting tube 601 is fixedly installed on the end of the inner traction rod 4, the connecting rod 602 is fixedly connected to both sides of the first threaded connecting tube 601, the U-shaped plate 603 is fixedly installed on the front side of the first threaded connecting tube 601, the connecting hole 604 is opened on the left and right sides of the U-shaped plate 603, the connecting hole 604 and the connecting rod 602 are rotatably connected, and the second threaded connecting tube 605 is fixedly installed on the front side of the U-shaped plate 603.

[0026] Furthermore, by providing the connecting rod 602 and the connecting rotating hole 604 , not only the outer traction rod 5 can be connected to the inner traction rod 4 , but also the outer traction rod 5 can be rotated around the inner traction rod 4 .

[0027] Specifically, the traction frame 1 includes a traction plate 101, a reinforcing rod 102, a clamping plate 103, a limiting groove 104 and a limiting rod 105. The two traction plates 101 are arranged in parallel and symmetrically. The reinforcing rod 102 is fixedly connected to the middle part of the two traction plates 101. The clamping plate 103 is fixedly installed at one end of the traction plate 101. The limiting groove 104 is opened at one end of the traction plate 101 close to the clamping plate 103. The limiting rod 105 is fixedly connected to the left and right sides of the clamping plate 103 and passes through the limiting groove 104.

[0028] Furthermore, by setting the reinforcing rod 102, the traction frame 1 can be effectively prevented from being deformed during the traction process, thereby enhancing the overall firmness of the traction frame 1. By using the limiting groove 104 and the limiting rod 105 in coordination, the rotation angle of the clamping plate 103 can be limited to a certain extent to avoid excessive bending angles.

[0029] Specifically, a first pin hole 7 is formed at the other end of the traction plate 101 , and a first pin shaft 8 is fixedly installed in the inner cavity of the first pin hole 7 .

[0030] Furthermore, by providing the first pin shaft 8 , the traction plate 101 can be connected to the tractor and the traction plate 101 can be fixed.

[0031] Specifically, the second pin holes 9 are formed on both the left and right sides of the clamping plate 103 , and the second pin shaft 10 is fixedly installed in the inner cavity of the second pin hole 9 .

[0032] Furthermore, by providing the second pin shaft 10 , the clamping plate 103 can be connected to the traction plate 101 .

[0033] Specifically, a mounting hole 11 is formed at the top of the clamping plate 103 , and third pin holes 12 are formed at the left and right sides of the mounting hole 11 . A third pin shaft 13 is fixedly mounted in the inner cavity of the third pin hole 12 .

[0034] Furthermore, by providing the third pin shaft 13 , one end of the traction frame 1 can be connected to the traction vehicle, and the traction frame 1 can be fixed.

[0035] Specifically, the traction plate 101 and the reinforcing rod 102 are connected by welding.

[0036] Furthermore, welding the reinforcing rod 102 between the two traction plates 101 can enhance the overall rigidity of the traction frame 1 and ensure stability during the traction process.

[0037] When in use, the traction plate 101 is installed at a suitable position on the tractor and fixed with the first pin shaft 8, so that the inner traction rod 4 is directly connected to the tractor, the clamping plate 103 is connected to the tractor by the third pin shaft 13, and the outer traction rod 5 is connected to the tractor, and each pin shaft is adjusted to ensure the stability and reliability of double-layer traction, and the tractor is operated for traction.

[0038] In summary, the inner traction rod 4 is directly connected to the tractor, and the outer traction rod 5 is suspended on the tractor, and the outer traction rod 5 can rotate around the inner traction rod 4. During the rotation of the outer traction rod 5, the limiting hole 15 on the arc plate 14 limits the rotation angle of the outer traction rod 5 to a certain extent. At the same time, the limiting grooves 104 on both sides of the traction plate 101 limit the rotation of the clamping plate 103 to avoid the traction frame 1 from bending too much. The double-layer traction rod is used in conjunction with the traction frame 1 to provide a larger contact area, thereby reducing the friction between the traction structure and the ground, enhancing the traction force, and facilitating the operation of the tractor. At the same time, it can protect the tractor and the tractor from damage, avoid friction between the tractor's frame and tires and the tractor, so as to ensure the stability and safety of the tractor during the traction process.
