Therefore, pretreatment of sheep manure and extraction of effective ingredients such as humic acid are of great significance for the preparation of high-quality organic fertilizers.

[0003] In the existing technical solutions, the methods for processing sheep manure include natural drying, manual turning of the pile, etc. These methods have the problems of low efficiency, unstable product quality, and high labor intensity.

[0004] Therefore, a sheep manure pretreatment device for preparing organic fertilizer is proposed. Utility Model Content
