[0021] The mesh screen is provided with two mesh screens, which are arranged up and down, and the mesh hole of the mesh screen located at the bottom is smaller than the mesh hole of the mesh screen located at the top. The two mesh screens are detachably connected with an anti-leakage component, which includes a flexible and retractable anti-leakage cylinder 10, and an upper fixing ring 11 is fixed on the top of the anti-leakage cylinder 10, and a plurality of upper fixing holes 15 are evenly distributed on the upper fixing ring 11 along the circumferential direction. An upper clamping block 12 cooperating with the upper fixing hole 15 is provided on the outer wall of the screen cylinder 3 of the upper mesh screen, and a lower fixing ring 13 is fixed on the bottom of the anti-leakage cylinder 10, and a plurality of lower fixing holes 18 are evenly distributed on the lower fixing ring 13 along the circumferential direction.

The setting of the anti-leakage component can prevent the leakage of the material screened by the upper mesh screen from falling on the lower mesh screen without affecting the swing of the two mesh screens. The anti-leakage component is detachable, which is convenient for cleaning or maintaining each mesh screen, and the operation is convenient and efficient, which improves the work efficiency.
