[0004] The above-mentioned lightweight agricultural machinery drive shaft still has certain shortcomings: since the lightweight agricultural machinery drive shaft does not have the function of being resistant to bending, once the lightweight agricultural machinery drive shaft is squeezed by external force, it will cause the lightweight agricultural machinery drive shaft to bend, which will affect the use of the lightweight agricultural machinery drive shaft. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a lightweight agricultural machinery drive shaft. By setting a bending-resistant component, when the drive shaft body is about to be affected by external force, the bending-resistant component arranged on the surface of the drive shaft body will work, and then the pressure-resistant protection plate will replace the drive shaft body to contact the equipment applying external force, and will transmit the external force to the arc-shaped connecting plate, the limiting telescopic rod and the buffer spring. When the buffer spring is acted on, the buffer spring will reduce the external force applied to the drive shaft body to ensure that the drive shaft body will not bend, thereby saving working time and solving the problems existing in the prior art.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a lightweight agricultural machinery drive shaft, comprising a drive shaft body, a bending-resistant component is fixedly sleeved on the surface of the drive shaft body, both ends of the drive shaft body are fixedly connected with a mounting shell, two first stabilizing plates are fixedly connected to the surface of the mounting shell symmetrically along the center, a first connecting ring is movably sleeved on the top of the first stabilizing plate, a protective rope is fixedly connected to the top of the first connecting ring, a second connecting ring is fixedly connected to the bottom end of the protective rope, a second stabilizing plate is movably sleeved on the surface of the second connecting ring, and a universal joint is movably sleeved on one end of the mounting shell.

[0008] Wherein, the anti-bending component includes a stable connecting tube and a connecting base, and the upper surface of the stable connecting tube is fixedly connected to a plurality of connecting bases in a circular array.

[0009] Wherein, a limited telescopic rod is fixedly connected to the upper surface of the connecting base, and a buffer spring is fixedly sleeved on the surface of the limited telescopic rod.

[0010] Wherein, the top end of the buffer spring is fixedly connected with an arc-shaped connecting plate, the upper surface of the arc-shaped connecting plate is bonded with a pressure-resistant protective plate, and the material of the pressure-resistant protective plate is a rubber component.

[0011] The interior of the stabilizing connection cylinder is adapted to the surface of the transmission shaft body, and the length of the stabilizing connection cylinder is smaller than the elongated length of the transmission shaft body.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. In the above scheme, the lightweight agricultural machinery transmission shaft is provided with a first stabilizing plate, a first connecting ring, a protective rope, a second connecting ring and a second stabilizing plate. When the transmission shaft is in use, the universal joint and the mounting shell are separated. At this time, the first stabilizing plate, the first connecting ring, the protective rope, the second connecting ring and the second stabilizing plate arranged on the surfaces of the two will work. Because the mounting shell is connected to the universal joint by two connection methods, it can be ensured that the universal joint will not be immediately separated from the transmission shaft body, so that the staff can maintain the transmission shaft in time, thereby enhancing the safety performance of the device;

[0014] 2. In the above scheme, the lightweight agricultural machinery drive shaft is provided with a bending-resistant component. When the drive shaft body is about to be affected by external force, the bending-resistant component arranged on the surface of the drive shaft body will work, and then the pressure-resistant protective plate will replace the drive shaft body to contact the equipment applying external force, and will transfer the external force to the arc-shaped connecting plate, the limiting telescopic rod and the buffer spring. When the buffer spring is acted on, the buffer spring will reduce the external force applied to the drive shaft body to ensure that the drive shaft body will not bend, thereby saving working time.

There are four second stabilizing plates 8, and the four second stabilizing plates 8 are equally divided into two groups. The bending-resistant component 2 includes a stabilizing connecting tube 21 and a connecting base 22. The upper surface of the stabilizing connecting tube 21 is fixedly connected to a plurality of connecting bases 22 in a circular array. The upper surface of the connecting base 22 is fixedly connected to a limited telescopic rod 23. The surface of the limited telescopic rod 23 is fixedly sleeved with a buffer spring 24. The top of the buffer spring 24 is fixedly connected to an arc-shaped connecting plate 25. The upper surface of the arc-shaped connecting plate 25 is bonded with a pressure-resistant protective plate 26. The material of the pressure-resistant protective plate 26 is a rubber component. The interior of the stabilizing connecting tube 21 is adapted to the surface of the transmission shaft body 1. The length of the stabilizing connecting tube 21 is less than the elongated length of the transmission shaft body 1.

[0025] Benefits: The arrangement of the limiting telescopic rod 23 is conducive to ensuring that the movement trajectory of the buffer spring 24 does not change when the buffer spring 24 is compressed, thereby enhancing the practicability of the device.

[0026] The working process of the utility model is as follows:
