Design and test of self-propelled sphaeroides globus spreading machine

Abstract This study presented the development and testing of a self-propelled spreading machine specifically designed for Sphaeroides globus cultivation. Traditional manual spreading methods were labor-intensive, inefficient, and inconsistent, often leading to increased labor costs and variability in spreading quality. The newly designed machine aimed to address these challenges by automating the spreading process, enhancing productivity, and reducing labor dependency. The machine, comprising a power unit, material box, scraper feeding mechanism, stirring device, and feeding device, was subjected to rigorous orthogonal testing to determine the optimal operational parameters. The identified parameters—discharging port height at 147 mm, driving wheel speed at 8 r min−1, and feeding port spacing at 186 mm—were critical in achieving uniform material distribution. Field tests conducted at the Shangqiu Henan Jinlong Mushroom Planting Base demonstrated the machine’s ability to deliver high-quality, uniform spreading, effectively replacing the labor of 6–8 individuals and improving spreading efficiency by 5–10 times compared to manual methods. The results highlighted the machine’s significant economic benefits, reducing operational costs and increasing productivity. The innovative design features, including a precise adjusting plate mechanism, scraper feeding mechanism, and stirring device, contributed to its high performance and reliability. The spreading machine met the requirements for Sphaeroides globus cultivation, providing a practical and efficient solution for large-scale operations. In summary, the self-propelled spreading machine represents a substantial advancement in mechanized fungi cultivation, offering improved productivity, reduced labor costs, and significant economic benefits. Future enhancements should focus on increasing material box capacity, incorporating advanced sensors, and conducting broader field tests to further refine the design, ensuring its viability for large-scale agricultural operations.
