Technical Field

[0001] The utility model relates to the technical field of earthworm impurity removal, in particular to an auxiliary impurity removal device of an earthworm separator. Background Art

[0002] Earthworms play three roles in the ecosystem: consumer, decomposer and regulator. It is generally believed that their position as consumers in the ecosystem is not important. Generally, only 3-6% of the energy entering the decomposition subsystem is consumed by earthworms. However, if the energy consumed in excrement and cocoons is added, the role of earthworms in the system's energy transfer will be greater. Earthworms affect the biological, chemical and physical characteristics of the ecosystem through activities such as feeding, burrowing and excretion. These factors in turn affect the earthworms themselves. Earthworms are saprophagous animals. They feed on rotten plants or other organic matter, swallowing soil and sand to obtain the organic matter therein.
