Because the sand box carries a large amount of steel slag to enter the box turner, the box turner can drop the steel slag onto the chain when driving the sand box to turn over, so that the chain is easy to be blocked, and the normal rotation of the conveying roller is influenced.

In the utility model, the transmission of the original chain sprocket 0 is optimized into the transmission of the gear by combining with fig. 2 and 3-8, and the gear is placed in the gear box 3, so that the tightness of the transmission mechanism is enhanced, and steel slag is prevented from entering the gear box 3 to influence the transmission of the gear.
