[0022] A slide groove 22 is provided on the inner side of the vibration frame 2, and the sieve mesh plate 7 is detachably inserted in the slide groove 22. The slide groove 22 and the sieve mesh plate 7 are fixed by bolts. During the operation, the sand and gravel cause serious wear and tear on the sieve mesh plate 7, and the service life is short. The detachable sieve mesh plate 7 is conducive to its replacement or maintenance, improves the replacement efficiency, and reduces the labor intensity of employees.

[0023] The mesh screen plate 7 comprises a fixing frame 71 and a mesh plate 72 , wherein the mesh plate 72 is fixed in the fixing frame 71 .

[0024] The mesh aperture of the mesh plate 72 is 0.01-0.05mm, the mesh plate thickness is 3mm, and a support beam 23 is horizontally provided on the vibration frame 2 to support the bottom of the mesh plate 72.

As the vibration material is transported to the end, the mountain-shaped material is spread to both sides by the cloth roller, which is conducive to the water in the fine sand to penetrate into the sieve mesh plate and be discharged with the vibration, thereby realizing vibration dehydration. It can ensure that the material is spread evenly and the dehydration effect is guaranteed.
