The seed pre-cleaner comprises a water reservoir 2 and a push plate 4. Support plates 1 are fixedly connected to the upper ends of both sides of the water reservoir 2, and the water reservoir 2 and support plates 1 can function as a single unit. A first filter plate 3 is fixedly connected within the water reservoir 2, and the first filter plate 3 tilts from the upper portion of the front vertical portion of the water reservoir 2 to the lower portion of the rear vertical portion. The push plate 4 is movably positioned above the first filter plate 3.

[0026] The length of the two support plates 1 is longer than that of the water reservoir 2 . The lower surface of the push plate 4 is parallel to the first filter plate 3 . The push plate 4 can move along the upper surface of the first filter plate 3 .

[0027] The seeds to be pre-cleaned are poured into the rear end of the water reservoir 2, and the push plate 4 pushes the seeds out of the water reservoir along the upper surface of the first filter plate 3. During the pushing process, the seeds flip back and forth between the angles of the first filter plate 3 and the push plate 4 and rub against each other to achieve a pre-cleaning effect. After the pre-cleaning, dust and seed shells will be separated from the seeds, the seed shells will float on the water surface, and the dust will sink to the bottom of the water.

[0028] A filtering mechanism is provided between the two support plates 1, and the filtering mechanism includes a second filter plate 9, a collecting plate 10 and a discharge plate 11. There are two collecting plates 10 and they are fixedly connected to both sides of the second filter plate 9. The rear end of the discharge plate 11 is hinged to the rear end of the collecting plate 10, and the front end is detachably placed on the lower end of the second filter plate 9. A collection groove is opened on one side of the discharge plate 11.

[0029] The rear side of the second filter plate 9 is arc-shaped and consistent with the curvature of the front end of the discharge plate 11 when it is flipped up.
