The rotating shaft 2 is clamped on the front and rear sides of the top of the mobile frame 1, and the rotating shaft 2 can rotate on the mobile frame 1. The storage rack 3 is connected between the rotating shafts 2 on both sides. The charging crucible 4 can be placed on the storage rack 3 for storage. The mobile frame 1 is provided with a blocking mechanism for blocking the top of the charging crucible 4 to prevent molten iron from splashing out. The mobile frame 1 is provided with a flipping mechanism. The flipping mechanism is used to flip the charging crucible 4 to pour out the molten iron in the charging crucible 4.

[0034] like Figure 3 and Figure 4 As shown, the baffle mechanism includes a connecting bracket 51, a baffle plate 52 and an electric push rod 53. The upper parts of the left and right sides of the mobile frame 1 are connected to the connecting brackets 51. The baffle plates 52 are slidably connected to the connecting brackets 51 on both sides. The baffle plates 52 can slide to block the top opening of the charging crucible 4 to prevent the molten iron in the charging crucible 4 from splashing out during the transportation of the molten iron. Electric push rods 53 are installed on the connecting brackets 51 on both sides. The two electric push rods 53 are respectively connected to the two baffle plates 52, so that the operation of the electric push rods 53 can drive the baffle plates 52 to move.

[0035] like Figure 5As shown, the flipping mechanism includes a reduction motor 61, a connecting frame 62, an arc rack 63 and a cylindrical gear 66. The reduction motors 61 are installed on the left and right sides of the top of the mobile frame 1. The output shafts of the two reduction motors 61 are connected to the connecting frame 62. The rear side of the left connecting frame 62 is connected to the arc rack 63, and the front side of the right connecting frame 62 is connected to the arc rack 63. The right side of the front rotating shaft 2 is connected to the cylindrical gear 66, and the right side arc rack 63 is engaged with the front side cylindrical gear 66. The left side of the rear rotating shaft 2 is connected to the cylindrical gear 66, and the left side arc rack 63 is engaged with the rear side cylindrical gear 66, so that the operation of the reduction motor 61 can drive the storage rack 3 to flip, which is used to drive the loading crucible 4 to flip and pour the molten iron.

[0036] like Figure 5 As shown, the flipping mechanism also includes a sliding frame 64, a pressure plate 65, a connecting sleeve 67 and an elastic member 68. The rear side of the left connecting frame 62 and the front side of the right connecting frame 62 are both connected to the connecting sleeve 67. The sliding frame 64 is slidably connected in the connecting sleeve 67. The bottom of the sliding frame 64 is connected to the pressure plate 65. The left pressure plate 65 is used to press the rotating shaft 2 on the rear side, and the right pressure plate 65 is used to press the rotating shaft 2 on the front side. An elastic member 68 is connected between the two pressure plates 65 and the connecting sleeve 67. The elastic member 68 is a compression spring.

[0037] When the molten iron needs to be transported by the metallurgical vehicle, the device can be used. When in use, the device can be placed at the laid railway first, then the device is moved to the charging position by moving the frame 1 to add molten iron, and the added molten iron can be added into the charging crucible 4. After the addition is completed, the moving frame 1 can be controlled to move along the railway to the subsequent process. During the transmission process, the extension rod of the electric push rod 53 can be controlled to extend to drive the blocking plate 52 to block the charging crucible 4, so that the molten iron in the charging crucible 4 is prevented from spilling out during the conveying process, and the stability during the conveying process is ensured. When the molten iron in the charging crucible 4 needs to be poured out after being conveyed to the appropriate position, the extension rod of the electric push rod 53 can be controlled to retract to drive the blocking plate 52 to reset and no longer block the charging crucible 4. Then the reduction motor 61 is controlled to operate to drive the connecting frame 62 to swing. When the connecting frame 62 swings, it can drive the arc gear rack 63 to move. The arc gear rack 63 moves to rub the cylindrical gear 66 to rotate. The cylindrical gear 66 rotates to drive the rotating shaft 2 and the storage frame 3 to rotate, so as to overturn the charging crucible 4 and pour out the material in the charging crucible 4. In the actual operation process, if the charging crucible 4 needs to be controlled to overturn backward, the left reduction motor 61 can be controlled to operate to drive the left connecting frame 62 to swing backward. If the charging crucible 4 needs to be controlled to overturn forward, the right reduction motor 61 can be controlled to operate to drive the right connecting frame 62 to swing forward. In this way, the molten iron can be transported by using the device, and the molten iron can be prevented from spilling out during the conveying process. The charging crucible 4 can also be automatically controlled to overturn. The elastic member one 68 can exert pressure on the sliding frame 64, so that the pressing plate 65 presses the rotating shaft 2, and the rotating shaft 2 is fixed more stably.
