[0024] As a preferred embodiment, the horizontal rod 41 and the vertical rod 42 are both configured as magnetic rods, and metal material is provided at the welding position, so that the magnetic frame 4 can easily adsorb metal impurities in the sand block.

[0025] Specifically, when the metal impurities absorb the sand, when the device housing 1 vibrates, the sand on the surface of the metal impurities is shaken off and falls.
