[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The two hydraulic cylinders drive the horizontal moving plates on both sides to move relative to each other until the two flipping mechanical arms are against the sand box, and the output shaft of the flipping motor drives the flipping mechanical arms and the sand box to flip.
