Abstract: In order to solve the problems of high labor intensity, difficult manipulation and prominent safety risks in the loading of fresh tobacco leaves in dense baking house, combined with the structure of the dense baking house and the technical requirements of tobacco leaf curing, an inclined rotary tobacco loading machine was designed, which was mainly composed of power platform, lifting device, horizontal moving device, inclined rotary device and PLC control system. Through the analysis of the process of tobacco leaf lifting, the chain lifting mechanism and the oil cylinder lifting mechanism were designed, and their structural parameters were determined. In order to ensure that the machine had good loading and unloading effect, analyses of the motion process of the rotating mechanism and the tilting mechanism were carried out. It was determined that the length of the smokecarrying rod was 650 mm, the distance between the two axes of the smokecarrying rod and the connecting shaft of the bevel gear was 13 mm, and also optimized the design of bevel gears by genetic algorithm. After the tobacco loading test in the dense baking house, according to the test results, it had been found that the working performance of the inclined rotary tobacco loading machine was reliable and stable, the average success rate of tobacco loading was 96.7%, and the average damage rate of tobacco was 7.8%. The research results can provide reference for the study of intelligent tobacco loading machine in dense baking house.
