[0003] When the existing tractor towing frame is in use, the spring and shock absorber are usually used to reduce the impact force between the tractor and the towing vehicle when the tractor brakes or accelerates. However, in actual use, we found that due to the integrated design of the towing frame, the spring inside the towing frame will gradually become less effective in resisting the impact force after long-term use, which will easily cause the towing frame to be damaged by the impact force. Therefore, how to solve this problem is what we need to consider. Utility Model Content

In view of the use problem of the traction frame, two buffer mechanisms are arranged, which can effectively reduce the impact force between the tractor and the towing vehicle during driving by cooperating with two shock absorbers. At the same time, the buffer mechanism can be quickly replaced to avoid the long-term use of the spring affecting the effect of the traction frame in absorbing the impact force, thereby effectively reducing the maintenance cost.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0022] Among them, it also includes two buffer mechanisms, both of which are used to reduce the impact force between the tractor and the towing vehicle when braking or accelerating. The buffer mechanism includes two limit frames 11, the inner walls of the two limit frames 11 are respectively slidably connected to the corresponding second connecting block 7 and the corresponding third connecting block 9, the two limit frames 11 are elastically connected by a spring 12, and the inner tops of the two limit frames 11 are both provided with limit slots 13;
[0023] Among them, a first C-shaped limiting rod 14 is provided at the upper end of the shell 1, and a second C-shaped limiting rod 15 is provided at the upper end of the first connecting block 3. The first C-shaped limiting rod 14 cooperates with the second C-shaped limiting rod 15 to limit the two buffer mechanisms. The first C-shaped limiting rod 14 and the second C-shaped limiting rod 15 are both composed of a horizontal part in the middle and vertical parts on both sides. The first C-shaped limiting rod 14 is fixed to the shell 1 by a first limiting bolt 16, and the second C-shaped limiting rod 15 is fixed to the first connecting block 3 by a second limiting bolt 17;
[0024] Among them, the two vertical parts of the first C-shaped limit rod 14 respectively penetrate the corresponding limit groove 13 and the corresponding first limit groove 8, and the two vertical parts of the first C-shaped limit rod 14 are respectively fitted with the corresponding inner wall of the limit groove 13 and the corresponding inner wall of the first limit groove 8, and the two vertical parts of the second C-shaped limit rod 15 respectively penetrate the corresponding limit groove 13 and the corresponding second limit groove 10, and the two vertical parts of the second C-shaped limit rod 15 are respectively fitted with the corresponding inner wall of the limit groove 13 and the corresponding inner wall of the second limit groove 10.
[0025] In the utility model, before use, the mounting plate 5 is first connected to the tractor, and then the mounting frame 6 is connected to the tractor, so that the device can be used normally.

Finally, install the first limit bolt 16 and the second limit bolt 17 respectively. In this way, the replacement of the two buffer mechanisms is completed. The whole process is convenient and quick. Only two buffer mechanisms need to be replaced to ensure the long-term shock absorption effect of the traction parts, and the maintenance cost is low.
