And a water spraying pipe is arranged on the frame at the lower part of the machine frame.

And a material receiving box is arranged below the first support plate and the second support plate.

And the spiral auger teeth are wrapped with wear-resistant rubber check rings.

And the silt screening equipment is connected with the magnetic separator.

The silt screening equipment provided by the invention is different from the traditional dry screening equipment, and can be used for directly carrying out wet screening on silt mixed with water and impurities. The specially arranged spiral auger can directly clean and remove impurities from silt extracted from a river, and then carries out classified screening through different screens so as to meet different production requirements. By using the silt screening equipment, the single machine (provided with two screening units) can produce 3 thousand cubic meters in one day, and the efficiency is high.
