The utility model sets a damping rod, and the movable blocks are symmetrically installed at the upper and lower ends of the damping rod with the center of the damping rod as the reference, and the two ends of the support spring are fixedly connected to the movable blocks at the upper and lower ends of the damping rod respectively. The upper end of the damping rod is rotatably connected to the base through the movable blocks, and the lower end is rotatably connected to the fixed shaft. When the movable block under the damping rod is inserted into the outer side of the fixed shaft, the damping rods at the front and rear sides of the bucket and the bottom surface of the bucket form an angle of thirty degrees, and the damping rod points to the bottom of the center of the bucket.

When the cart passes through the crack in the road, the gear on the front side of the lower end of the wheel frame is suspended first. Due to the restriction of the gear on the crawler track, the crawler track remains in its original shape. At this time, the gravity of the bucket will be transmitted to the gear on the rear side of the lower end of the wheel frame. As the cart moves, the gear on the front side of the wheel frame passes over the crack in the road, and then the gear on the rear side of the wheel frame is suspended. The gravity of the bucket will be transmitted to the gear on the front side of the lower end of the wheel frame to ensure that the cart can pass through the crack smoothly, thereby avoiding the impact of road factors on transportation.
