The device starts to be started, a user puts sand into the inner side of the placing chamber 221 and presses the electrifying button 4, then the motor one 223 and the motor three 301 are electrified, the motor one 223 is electrified to operate to drive the belt wheel 224 to rotate, the belt wheel 224 rotates to drive the transmission belt 225 to rotate, the transmission belt 225 rotates to transmit the sand inside the placing chamber 221 to the inside of the sealing shell 21 through the transmission port 226, the sand entering the inside of the sealing shell 21 falls on the surface of the filtering elastic plate 228 and drives the filtering elastic plate 228 to vibrate under the action of gravity, the filtering elastic plate 228 vibrates to drive the telescopic rod 2210 to contract, so that the sand on the surface of the filtering elastic plate 228 enters the inside of the guide pipe 229 through the filtering elastic plate 228 and is transmitted to the surface of the vibrating plate 304, meanwhile, crushed stone enters the inner side of the feeding port 232 through the filtering elastic plate 228 until the crushed stone contacts with the swing rod 233 and drives the swing rod 233 to rotate, and the crushed stone enters the surface of the crushing plate 2314 inside the protective shell 231 through the feeding port 232, meanwhile, the swing rod 233 swings until the swing rod is contacted with the contact 234, then the second motor 235 is electrified to operate to drive the screw rod 236 to rotate, the screw rod 236 rotates to drive the reciprocating block 237 to rotate, the reciprocating block 237 rotates to drive the connecting rod 238 to rotate, the connecting rod 238 rotates the sliding plate 2310 to slide on the inner side of the sliding rail 239, the sliding plate 2310 slides to drive the fixing plate 2311 to slide on the outer side of the fixing plate 2311, the fixing plate 2311 slides to compress the spring 2313, the fixing plate 2311 slides to drive the impact blade 2312 to move to crush the crushed stones under the supporting action of the crushing plate 2314, the crushed stones enter the discharge pipe 2315 through the crushing plate 2314 and are conveyed to the surface of the vibrating plate 304, similarly, the swing rod 233 stops rotating and is not contacted with the contact 234, then the second motor 235 stops being electrified, meanwhile, the third motor 301 is electrified to operate to drive the turntable 302 to rotate, the turntable 302 rotates to drive the connecting plate 303 to rotate, the connecting plate 303 rotates to drive the vibrating plate 304 to vibrate on the inner side of the collecting plate 306, vibration board 304 vibrates to carry out the secondary screening with sand and drops in the inside of collecting plate 306, and iron metal receives the attraction of magnetic force until adsorbing in the magnetic field of magnet 307 in the sand simultaneously, and the inside sand of collecting plate 306 drops in the inside of casing 1 through opening 308, and the user can handle collecting iron metal through taking off collecting plate 306.

When the sand treatment is completed, the user presses the power button 4 again, and the first motor 223 and the third motor 301 stop being powered on.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
