Description

Technical Field

[0001] This utility model relates to the field of earthworm farming equipment technology, and in particular to a mechanized earthworm collection device. Background Technology

[0002] Livestock and poultry manure contains a large amount of undigested protein and crude fat. However, antibiotics, trace elements, and drugs added during animal feeding also leave residues in the manure. Earthworms, as common decomposers in ecosystems, can decompose organic solid waste into humus. Earthworm farming, as an important method for high-value resource utilization of livestock and poultry manure, has advantages such as simple technology, low processing costs, and high resource utilization rate. Besides increasing the bioavailable components in manure and improving its added value, it also utilizes the biological enzymes and endogenous microorganisms secreted in the earthworm's intestines to decompose and transform ARBs and ARGs in livestock and poultry manure. During earthworm farming, organic waste is transformed into stable, high-quality manure that can be used for soil improvement through the earthworm's digestive system. Earthworm castings are characterized by comprehensive nutrients, good water permeability and aeration, and high stability. They also contain a large number of beneficial microorganisms and plant growth regulators, which not only improve soil nutrients but also improve soil structure, increase the content of inorganic nitrogen and nitrate nitrogen in the soil, thereby enriching the soil. Earthworm castings play a vital role in promoting plant growth, suppressing soil-borne plant diseases, and restoring the soil environment. Farmed earthworms can be processed into animal-derived protein feed, and earthworms also possess unique medical and biological benefits, showing broad prospects for use in medicine, healthcare, and food. As a clean and environmentally friendly bioreactor, earthworm farming yields high-protein live earthworms and produces earthworm castings, known as the king of organic fertilizers. In recent years, due to its low investment, high economic returns, and large market demand, earthworm farming has become an important source of income for some rural farmers.

[0003] In existing technologies, earthworms are mostly collected manually, which is labor-intensive and inefficient. In addition, existing collection devices are simple in structure and have unsatisfactory collection results. They also require manual separation and cleaning of earthworms, which is inefficient and results in high labor costs for earthworm collection.

[0004] Therefore, a mechanized earthworm collection device is proposed. Utility Model Content
