[0019] When in use, when unloading is required, the linked ratchet structure 12 operates so that the ratchet 123 is stuck on the meshing tooth 71, causing the swing wheel 7 and the connecting plate 8 to rotate synchronously. Then the hydraulic cylinder 10 pushes the top plate 11 up, lifts the connecting plate 8 and rotates clockwise, thereby causing the swing wheel 7 and the lever 4 to rotate synchronously. After rotating 90°, the wedge block at the front end of the limiting component 13 is embedded in the position of the meshing tooth 71 to play a limiting role. After unloading is completed, the limiting component 13 contracts and the linked ratchet structure 12 disengages from the meshing tooth 71, causing the swing wheel 7 to rotate counterclockwise under the action of gravity and return to its original position. At the same time, a buffer can be set at the bottom of the lever 4 to reduce the shaking of the lever 4 and shrink the hydraulic cylinder 10 to its original position.

[0020] The meshing teeth 71 provided on the swing wheel 7 are spaced 30 degrees apart from each other, and six groups of meshing teeth 71 are provided. Meanwhile, a counterweight 15 is installed on the side of the swing wheel 7. The counterweight 15 ensures the stability and balance of the structure.

[0022] The U-shaped bracket 3 includes a bottom bracket 31 and a bracket cover 32 hinged on the bottom bracket 31, and the groove of the bracket cover 32 is stuck on the outside of the bottom bracket 31. At the same time, a U-shaped groove is arranged inside the bottom bracket 31 to facilitate the installation of the slag bucket. The bracket cover 32 structure has the effect of limiting and dustproofing.
