Abstract. In recent years, the rapid development of China's agricultural breeding industry has led to a swift increase in the generation of poultry and livestock manure, causing significant environmental pollution and posing threats to human health and safety. Therefore, it is essential to transform waste from poultry and livestock manure into valuable resources by producing organic fertilizers. To address the issues of low work efficiency, uneven mixing, and easy clogging and accumulation at the end in traditional organic fertilizer processing equipment, a dual-shaft horizontal mixer for organic fertilizer is designed in this study. This paper analyzes the overall structure of the dual-shaft horizontal mixer for organic fertilizer, including the selection of the electric motor, analysis of the transmission system, and analysis of the mixing device, to determine a scheme. Subsequently, the design and calculation of the transmission device's belt drive are conducted, followed by the design and calculation of the transmission device's reducer. Then, the design and calculation of other components of the transmission device are carried out, including the selection of the coupling and the design calculation of the driving gear set. Finally, an analysis of the mixing device is performed.
