摘要

开发螺旋喂料机的流速模型和优化卸料性能对于实现自动化智能精确喂料至关重要。考虑到料斗和螺旋输送机的耦合结构参数，本研究构建了螺旋输送机的质量流量模型。该模型是通过单因素测试和中央复合设计（CCD）响应面测试建立的，并通过实际卸料测试进行了验证。结果表明，料斗-螺旋输送机系统的卸料率主要受螺旋输送机本身的影响。在结构参数中，料斗倾角和料斗卸料口长度对填充系数有显著影响。验证测试表明，预测质量流量与模拟质量流量之间的平均误差为 6.8%，与实际质量流量之间的平均误差为 5.0%，这表明该模型具有很高的精度和准确性。

Modeling the Discharge Rate of a Screw Conveyor Considering Hopper–Conveyor Coupling Parameters

Developing a flow rate model for the screw feeder and optimizing discharge performance are crucial for achieving automated intelligent precision feeding. This study constructs a mass flow rate model for screw conveyors, considering the coupled structural parameters of the hopper and screw conveyor. The model is developed using single-factor tests and central composite design (CCD) response surface tests and is validated through actual discharge tests. Results indicate that the discharge rate in the hopper–screw conveyor system is primarily influenced by the screw conveyor itself. Among the structural parameters, the hopper inclination angle and the hopper discharge opening length significantly affect the filling coefficient. Validation tests show an average error of 6.8% between the predicted and simulated mass flow rates and 5.0% with the actual mass flow rate, demonstrating the model’s high precision and accuracy.
