Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, and in particular to a straw composting device for organic fertilizer production. Background Technology

[0002] Straw composting, as an agricultural wisdom derived from the natural cycle, focuses on transforming crop straw—the residue left after harvest—into a valuable resource that nourishes the soil and promotes plant growth. Through a series of scientific and meticulous operations, these raw materials undergo a complex composting process under specific conditions, ultimately transforming into environmentally friendly organic fertilizer rich in various nutrients.

[0003] In current technological practices, to improve composting efficiency and quality, flexible rotating crushing rollers are often used to initially crush straw raw materials. The crushed straw is then evenly mixed into a specific mixture to ensure the full integration and interaction of various components during composting. However, because existing operating methods require manual intervention—removing the crushed straw from the processing equipment before mixing—this extra step not only increases labor intensity but also leads to a decrease in overall operational efficiency due to frequent transfers and waiting times.
