The double-spiral feeder is fixed in the feeding bin through the rotating device.

[0004] Although the above-mentioned existing technology can realize the feeding of chlorinated organic contaminated soil, in the actual use process, due to the fact that the chlorinated organic contaminated soil contains a large amount of clay minerals, these mineral particles will form strong cohesive force under the joint action of water and organic pollutants, resulting in the adhesion of the soil into blocks.
