The bucket body is vertically arranged in the middle of the top surface of the base, and the bottom of the bucket body passes through the top surface of the base and extends into the inner cavity of the base; horizontal slots and vertical retaining slots are arranged on the front and rear side walls of the bucket body from top to bottom in sequence;

[0006] Two groups of rotating covers are symmetrically arranged on the bottom surface of the bucket body, and the rotating covers are arranged in the inner cavity of the base. The front and rear ends of the outer sides of the two groups of rotating covers are respectively hinged to the front and rear side walls of the base through rotating shafts; two groups of arc sliding grooves are symmetrically arranged at the positions corresponding to the flipping tracks of the inner sides of the two groups of rotating covers, and the rotating shafts at the front and rear ends of the inner sides of the two groups of rotating covers are arranged in the arc sliding grooves;

[0007] The hanging device includes a lifting ear, a cross beam, two groups of cross beam frames respectively located on the front and rear sides of the bucket body and four groups of pushing plates, the cross beam is arranged above the bucket body, the lifting ear is arranged in the middle of the cross beam, the upper ends of the two groups of cross beam frames are respectively hinged to the two ends of the cross beam, the lower ends of the cross beam frames pass through the horizontal card slot and the vertical retaining slot in turn and are hinged to the upper ends of the two groups of pushing plates, the lower ends of the pushing plates are respectively hinged to the front and rear ends of the inner sides of the two groups of rotating covers through the rotating shafts arranged in the circular arc slide groove; the pushing plate pushes the rotating shaft in the circular arc slide groove, so that the rotating cover is flipped around the rotating shaft in the inner cavity of the base to realize the closing and opening of the bottom surface of the bucket body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When the transport steel bucket is placed on the base of the transport trolley, the base presses the rotary cover horizontally to prevent the rotary cover from falling and affecting the collection of scrap steel. When the unloading steel bucket is unloading, the crossbeam tends to the left side of the bucket body, the horizontal slot limits the inclination angle of the crossbeam, and the vertical stopper limits the up and down movement of the push plate; the coordinated use of the rotating lock and the lock baffle ensures that the crossbeam always falls on one side during the unloading process of the unloading steel bucket, which will not affect the unloading;

[0014] 2. After the unloading of the steel bucket is completed, the transfer trolley transports the transport steel bucket out, unlocks the rotating lock, and the crane hook lifts the lifting lug for transportation. The lifting lug support plate makes the direction of the lifting lug present the most suitable lifting position for the crane hook. During transportation, the push plate is at the highest point, and the rotating sealing plate is tightened to prevent the scrap steel in the transport steel bucket from falling.

[0015] The invention has a simple structure and is easy to operate, thereby improving the efficiency of transferring and unloading scrap steel. BRIEF DESCRIPTION OF THE DRAWINGS
