[0039] Through the design of the driving wheel 5, the conveyor belt 6 and the driven wheel 7, when the driving wheel 5 rotates, the driving wheel 5 and the driven wheel 7 will drive the conveyor belt 6 to rotate.

[0040] Wherein, the driving component includes a driving motor 4;

[0041] The side surface of the driving motor 4 is fixedly connected to the side surface of the machine body 1 , and the driving motor 4 is transmission-connected to the driving wheel 5 .

[0042] By driving the motor 4 , the driving wheel 5 drives the brush block 8 through the conveyor belt 6 to wipe the sand screening plate 2 back and forth.

[0048] The reciprocating assembly includes a square port 11 and a cam 12;

[0049] The square opening 11 is disposed inside the stopper 10 , and the inner wall of the square opening 11 is movably sleeved with the outer surface of the cam 12 .
