[0033] The rear part of the carriage is designed in a dovetail shape. In other words, the material outlet end of the bottom plate formed by connecting the left bottom plate 11 and the right bottom plate 21 is slightly tilted upward. When the vehicle is fully loaded, the material loaded in the carriage is not easy to spill.

After the car body is installed on the frame, the bucket pin 140 between the two bucket pin seats 150 falls on the mounting seat on the frame that cooperates with it. By increasing and decreasing the number of bucket pin adjustment gaskets 120, the movement of the car body can be prevented, and the centering installation of the car body can be accurately achieved. The adjustment gasket 120 realizes the adjustment and filling of the gap between the bucket pin 140 and the mounting seat on the frame. When the car body is unloaded and lifted, the car body rotates around the bucket pin 140, that is, the bucket pin 140 is the rotating shaft.

[0042] In this embodiment, a steel plate with reliable strength, good plasticity, good welding performance, strong low-temperature impact toughness and good wear resistance is selected to design the carriage body. The designed carriage body has reliable strength, reasonable stiffness matching, strong impact resistance, good wear resistance and service life that meets user requirements. The carriage body does not need to be paved with wear-resistant plates. The weight reduction ratio of the carriage is 10% to 15% compared with the traditional carriage of the same tonnage vehicle. Therefore, the arc-shaped carriage of this solution achieves a lightweight design.

[0043] Finally, it is necessary to explain here that the above embodiments are only used to further illustrate the technical solution of the utility model in detail and cannot be understood as limiting the protection scope of the utility model.
