[0028] Working principle: First, when the U-shaped ore bucket truck is transporting materials, the pulling plate 606 can be pushed on both sides of the bucket 2, and the rain shield 604 can be pulled out by pulling the plate 606 to cover the surface of the bucket 2. Then, the pulling plate 606 can be rotated on one side of the fixed plate 607 through the slider 609 to make the rain shield 604 cover the bucket 2. Then, the fixing nut 611 can be rotated at one end of the screw 610 to lock the pulling plate 606, and then the material can be transported. When unloading is required, the rain shield 604 is opened, and then the bucket 2 is lifted by the hydraulic push rod 3. When most of the material is unloaded, the worm 405 on one side of the worm wheel 402 is driven to rotate by the driving motor 401, and the worm 405 drives the threaded rod 404 to rotate. When the threaded rod 404 rotates, the connecting plate 407 and the push plate 406 are driven to move, and the push plate 406 can push the remaining material out of the bucket 2.
