[0036] Specifically, the dumping assembly contains molten iron, and the driving assembly is driven to transmit the torque to the transmission assembly, and the transmission assembly drives the dumping assembly connected thereto to rotate, and the dumping assembly rotates in a direction perpendicular to the travel direction, that is, the first rotating shaft 22 is arranged along the travel direction, and the slideway 3 is welded into a whole by steel plates, and the slideway 3 is welded and connected to the side wall of the frame 1, and is arranged on the side where the casting port 6 of the dumping assembly is located, and the slideway 3 is arranged at the position of the casting port 6, and is arranged below the casting port 6. When the dumping assembly rotates until the molten iron flows out of the casting port 6, the slideway 3 guides the molten iron in the dumping assembly to flow out of the casting port 6. The molten iron flows into the funnel 4, which is arranged on one side of the frame 1 through an adjustment component, specifically under the slide 3. The adjustment component drives the funnel 4 to move so that the central axis of the funnel 4 coincides with the central axis of the sand box 21, so that the molten iron flowing into the slide 3 enters the funnel 4, and the molten iron in the funnel 4 enters the sand box 21 to solidify, thereby reducing the risk of molten iron splashing during casting and guiding the molten iron to enter the sand box 21. This casting vehicle is easy to operate, has no special requirements for workers, and does not need to be modified for the original casting workshop. It has high applicability and improves production safety by guiding the molten iron using the slide 3 and the funnel 4.
[0037] Specifically, refer to Figure 4 and Figure 5As shown, the adjustment assembly includes four sections of rotating arms 5 and a control rod, and two adjacent rotating arms 5 are connected by a second rotating shaft 7 and a copper sleeve, and the control rod is arranged on the rotating arm 5 near the funnel 4.
