Fracture-proof agricultural machinery traction device

The agricultural machine traction device comprises a scarifier shell, the side wall of the scarifier shell is fixedly connected with a sliding rail and two sets of symmetrically-arranged protruding blocks, the side walls of the protruding blocks are provided with penetrating through holes, and the interiors of the through holes are rotationally connected with two-way threaded rods; and the end part of the bidirectional threaded rod is fixedly connected with a rotating wheel. According to the agricultural machine traction device capable of preventing breakage, the buffer spring is a rubber spring, has certain internal resistance and can absorb impact and high-frequency vibration, the telescopic rod is rotationally connected between the top plate and the supporting plate and is supported through the buffer spring, and therefore the top plate and the scarifier shell can rotate; when the scarifier shakes, the buffer spring twists, so that torsion is generated, the connecting plate can quickly restore to the origi
