Description

Technical Field

[0001] This utility model relates to the field of earthworm farming technology, specifically to a soil screening device for earthworm farming. Background Technology

[0002] Earthworm farming is an activity that utilizes the biological characteristics of earthworms for ecological agriculture or resource recycling. Earthworms can transform organic waste, such as livestock and poultry manure, crop straw, and household garbage, into high-quality organic fertilizer, thus achieving resource recycling. Earthworm castings are a highly efficient organic fertilizer, rich in various nutrients and beneficial microorganisms needed by plants, and have a significant effect on improving soil structure and increasing soil fertility. Earthworm farming can not only process organic waste and reduce environmental pollution, but also generate economic benefits through the sale of earthworms and earthworm castings.

[0003] Soil used for earthworm farming needs to be screened before use to remove impurities, stones, and oversized particles, making the soil finer and more conducive to earthworm digging and movement. Earthworm farming soil screening devices typically combine mechanical vibration and sieves for screening and processing. After the soil enters the device through the feed inlet, impurities and oversized particles are separated by the sieve under the action of vibration, while the finer soil passes through the sieve and is discharged.

[0004] Common earthworm farming soil screening devices involve adding various materials directly to the selected soil after screening it, adjusting the soil texture and fertility to make it more suitable for earthworm growth. However, the screened soil may contain pathogens and pests, affecting earthworm growth. Therefore, this application proposes an earthworm farming soil screening device. Utility Model Content
