When the field ridge is crossed, the rear wheels are too high, and the chassis is in an inclined state, so that the spray rod moves relative to the horizontal ground. The chassis mass center can also move forward, easily takes place the potential safety hazard. After the swing frame device is added, the invention can be used for solving the problems of the prior art. When the rear wheel assembly is too high, the right swing frame assembly 6 and the left swing frame assembly 15 rotate around the main shaft 135, and the right frame connecting frame 4 and the left frame connecting frame 17 rotate around the frame connecting shaft, so that the fluctuation of the road surface does not influence the upper frame, and the upper frame can continuously keep a horizontal state.
When the vehicle runs on an uneven road surface, on one hand, the swing of the right swing frame assembly 6 and the swing of the left swing frame assembly 15 can be profiled to the ground, on the other hand, the vibration energy transmitted through the tire assembly is transmitted to the right swing frame assembly 6 and the left swing frame assembly 15, the suspension 2 is arranged between the right swing frame assembly 6 and the left swing frame assembly 15 and the upper layer vehicle frame, the vibration energy can be absorbed and dissipated, the impact is relieved, and the stability of the upper layer vehicle frame and the stability of the spray rod are guaranteed.
