The ore slides along the primary filter plate 12 through the connecting port 13 and the second feed port 21 to the secondary filter plate 22. The secondary filter plate 22 is squeezed and driven by the weight of the ore to squeeze the active end of the telescopic rod 23, driving the liquid in the rodless cavity of the telescopic rod 23 to flow through the pipeline into the rodless cavity of the sparse hole telescopic rod 31, and the active end of the sparse hole telescopic rod 31 is extended, the baffle 33 isolates the first feed port 11, and the sparse hole needle 321 on the pressing plate 32 is inserted into the filter hole of the primary filter plate 12.
