This device uses a specific suspension or traction method to firmly mount the agricultural machinery and implements on the tractor, thereby ensuring that the agricultural machinery and implements can operate efficiently and stably during operations such as tillage, sowing and harvesting.

[0003] When the towing device in the prior art is in use, the connection parts between the tractor and the agricultural machinery are fixedly connected. When encountering bumpy roads, the height between the moving tractor and the agricultural machinery changes continuously, which can easily cause damage to the connection parts. Moreover, when the road surface is bumpy, the agricultural machinery is fixedly connected to the rear of the tractor, and one side of the agricultural machinery is easily lifted up, making it impossible to cultivate the soil. Summary of the invention

[0004] The utility model aims to solve the problem that when the towing device in the prior art is in use, the connection parts between the tractor and the agricultural machinery are all fixedly connected. When encountering a bumpy road section, the height between the moving tractor and the agricultural machinery changes continuously, which easily causes damage to the connection parts. Moreover, when the road surface is bumpy, the agricultural machinery is fixedly connected to the rear of the tractor, one side of the agricultural machinery is easily lifted up, and the soil cannot be cultivated. A towing device for agricultural machinery is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A farm machinery towing device comprises a traction arc ring and a mounting cross bar, wherein an anti-dropping folding plate is fixedly arranged on the top of the traction arc ring, and a limiting pin is movably inserted into the traction arc ring below the anti-dropping folding plate, and the limiting pin is movably inserted into a vertical cylinder along the vertical direction, an extension tube is fixedly arranged on the side of the vertical cylinder, and the other end of the extension tube is movably inserted into the interior of the limiting cylinder, and a connecting shock-absorbing component is arranged between the limiting cylinder and the mounting cross bar to reduce damage to the farm machinery support frame caused by road bumps.

[0007] Optionally, an arc-shaped groove is opened on the side of the limiting cylinder, and a limiting bolt is inserted into the arc-shaped groove.

[0008] Optionally, the connection shock-absorbing assembly includes a vertical shift seat, a containing frame, and a vertical shift block. The vertical shift seat is fixedly connected to the bottom of the limiting cylinder, and the vertical shift blocks are symmetrically fixedly arranged on the side surfaces of the vertical shift seat.

[0009] Optionally, the front and rear sides of the accommodating frame are provided with vertical movement grooves, the vertical movement block extends into the vertical movement groove, the bottom of the vertical movement block is fixedly connected to one end of a connecting spring, and the bottom end of the connecting spring is fixedly connected to the bottom of the vertical movement groove.

[0010] Optionally, a mounting cross bar is fixedly provided on the front side of the vertical shift seat, and mounting holes are provided at the four corners of the side of the mounting cross bar and the four corners of the traction arc ring.

[0011] Optionally, the end of the limiting bolt is threaded into the side wall of the extension tube, and the width of the head of the limiting bolt is greater than the width of the arc groove.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The main structure of the utility model includes a mounting cross bar, a connecting shock-absorbing assembly and a traction arc ring. The traction arc ring is used to connect with the tractor, and the mounting cross bar and the connecting shock-absorbing assembly are used to fix with the agricultural implement. The connecting shock-absorbing assembly allows the agricultural implement to be relatively displaced with the tractor in the vertical direction, which can alleviate to a certain extent the problem that when encountering bumpy roads, the height between the moving tractor and the agricultural machinery and equipment changes continuously, which is easy to cause damage to the connection parts.

[0014] 2. The connection shock-absorbing assembly of the utility model is indirectly connected to the connection arc ring through a limit tube and an extension tube, so the agricultural implement installed on the mounting cross bar can rotate within a certain range along the horizontal axis, thereby solving the problem that when the road surface is bumpy, the traditional agricultural implement is fixedly connected to the rear of the tractor, one side of the agricultural implement is easy to tilt up, and the soil cannot be cultivated.
