Analysis and improvement of transport performance of eccentric retractable finger type conveyor
摘要
Abstract
In order to improve the transport efficiency of the eccentric retractable finger type con-veyor , the retractable finger type mechanism of 4FZ-2000A self-propelled straw bundling machine was studied .The transport performance and its influencing factors of the device were an-alyzed .It was determined that the retractable finger rotary center met the conveying requirements in the fourth quadrant ,and the retractable finger was collocated based on the actual demand .On this basis ,a mathematical model for the transport capacity in a single transport cycle was estab -lished ,and the parameters of affecting transport capacity were determined .The structure was de-signed and optimized by using the virtual prototype technology which took the structural parame-ters of the device as design variables and the maximum transport capacity in a single transport cy -cle as the objective function .The results showed that when the retractable finger shaft bracket length was 54 .2 mm ,the length of the telescopic link was 190 mm ,the angle between retractable finger shaft bracket and vertical direction was 10° and the installation height was 234 mm ,the maximum transport capacity was 0 .79 kg ,which was 36 .9％ higher than that before optimization . The research will lay a foundation for further study of the dynamics peculiarity of the device ,and provide the theoretical basis for the actual design and production of retractable finger type conveyors .关键词
