[0023] As Figures 1-4 shown, the buffer hanging rack provided in this embodiment includes a sleeve 1 and hanging components 2 arranged on both sides of the sleeve 1. A fixing plate 3 is fixedly installed at the central position inside the sleeve 1. A plurality of auxiliary rods 4 are fixedly installed on both sides of the fixing plate 3. A limiting disc 5 is arranged on the plurality of auxiliary rods 4. One end of the auxiliary rod 4 far from the fixing plate 3 penetrates through the limiting disc 5 and extends to one side of the limiting disc 5. And a plurality of first buffer springs 6 are arranged between the auxiliary rod 4 and the limiting disc 5. One ends of the plurality of first buffer springs 6 are fixedly connected to the auxiliary rod 4, and the other ends of the plurality of first buffer springs 6 are fixedly connected to the limiting disc 5. The first buffer springs 6 are sleeved on the outside of the auxiliary rod 4. Two second buffer springs 9 are arranged inside the sleeve 1. One end of the second buffer spring 9 is fixedly connected to one side of the limiting disc 5, and the other end of the second buffer spring 9 is fixedly connected to the inner side wall of the sleeve 1. The hanging components 2 on both sides of the sleeve 1 are used for the connection between the tractor and the agricultural implement. When the tractor pulls the agricultural implement and travels on a bumpy road section, the hanging components 2 buffer and slide inside the sleeve 1 through the mutual cooperation of the first buffer springs 6 and the second buffer springs 9, thereby preventing the hanging rack from breaking, and thus greatly improving the service life of the hanging rack.

[0024] Furthermore, as Figure 1 、 Figure 2 、 Figure 3 shown, the hanging component 2 includes a hanging block 201. A hanging hole 202 is opened on the hanging block 201. One side of the hanging block 201 is rotatably connected with a rotating rod 203. A hanging rod 204 is fixedly installed on the rotating rod 203. Threads are arranged on the outside of the hanging rod 204. Long nuts 7 are arranged on both sides of the sleeve 1. One end of the long nut 7 close to the sleeve 1 is fixedly installed with a sliding rod 8. The other end of the sliding rod 8 is fixedly connected to the limiting disc 5. And one end of the long nut 7 far from the sliding rod 8 is threadedly connected to the hanging rod 204. The hanging rack is fixed on the tractor and the agricultural implement through the hanging hole 202 on the hanging block 201 to ensure that the tractor suspends and pulls the agricultural implement. Then, by adjusting the length distance between the hanging rod 204 and the sliding rod 8 inside the long nut 7, the distance between the hanging component 2 and the sleeve 1 is adjusted, thereby improving the practicability of the hanging rack.

[0025] Furthermore, as Figure 1 , Figure 3 and Figure 4 shown, a limiting rod 10 is fixedly installed on the limiting disk 5. The limiting rod 10 penetrates through the limiting disk 5 and extends to one side of the limiting disk 5. A plurality of notches 11 are formed on the sleeve 1. The limiting rod 10 is located inside the notch 11, and the limiting rod 10 slides inside the notch 11. The sliding rod 8 is limited by the sliding of the limiting rod 10 inside the notch 11, thereby preventing the hanging assembly 2 from falling off the sleeve 1.

[0026] As Figures 1-4 shown, the principle of the buffer-type hanging rack provided in this embodiment is as follows:

[0027] The buffer-type hanging rack includes a sleeve 1 and hanging assemblies 2 arranged on both sides of the sleeve 1. A fixed plate 3 is fixedly installed at the central position inside the sleeve 1. A plurality of auxiliary rods 4 are fixedly installed on both sides of the fixed plate 3. A limiting disk 5 is arranged on the plurality of auxiliary rods 4. One end of the auxiliary rod 4 far from the fixed plate 3 penetrates through the limiting disk 5 and extends to one side of the limiting disk 5. A plurality of first buffer springs 6 are arranged between the auxiliary rod 4 and the limiting disk 5. One end of the plurality of first buffer springs 6 is fixedly connected to the auxiliary rod 4, and the other end of the plurality of first buffer springs 6 is fixedly connected to the limiting disk 5.
