摘　　要：针对在实际应用中螺旋输砂器输砂量理论计算结果与试验结果相差较大的问题,提出了一种新的试验台架设计方案,可实现精确称量螺旋输砂器输砂量,介绍了试验台架分流装置、变倾角装置和称量装置的结构设计,设计了试验台架的二级控制系统。目前,该试验台架已投入使用,各系统均能正常工作,为进一步研究螺旋输砂器输送特性与结构参数之间关系奠定了试验基础。Aiming at the problem that the difference between theoretical calculation results of sand transport mass and test results is large in the real application of spiral sand conveyor, a new test bench design scheme achieving precision weighing of sand transport mass of spiral sand conveyor is proposed, and the structure design of shunt device, variable angle device and weighing device of the test bench are introduced, and secondary control system of test bench is designed~ At present, the test bench has been put into use, and each system can work normally, establishing the experimental foundation for further study on the relationship between transport properties of spiral sand conveyor and structure parameters.
