The problem of residual film pollution is serious in the cotton fields of Xinjiang, and the mechanical recycling of residual film is the main recycling method. In the existing residual film recycling machines, spring tine or telescopic rod tine film producing device are commonly used, thus the phenomenon that residual film winds work piece is prone to occur, affecting the effect of film producing and removal. In view of the above problems, a sprocket conveying residual film recycling machine of casting film with film producing throwing, sprocket conveying and automatic film stripping was designed according to the advantages of the existing models based on the principles of planer cylinder knife film producing and casting film cylinder knife throwing. The machine was mainly composed of film-producing device, conveying device, film stripping device, transmission system and film collecting box. The residual film by throwing up film with chain gear conveying realized the separation of residual film and film clod, ensured the reliability of automatic stripping, and the scraper stripping mechanism to complete unloading film, plastic film, solved the difficult problem of removing film winding. The results of the field experiment showed that when the operating speed was 4~7km/h, the average value of the recycling rate of residual film was 90.6%, the average value of working efficiency of the machine was 0.84hm2/h, and the average value of impurity rate of residual film was 3.971%. When the operating speed was fast, the working efficiency was improved, but the recycling rate was reduced, and the impurity rate was increased. When the operating speed was 5km/h, the average value of the recycling rate was 91.8%, the working efficiency was 0.733hm2/h, and the average value of impurity rate was 2.605%, so it was more suitable operation speed. The machine was operated well, which had good effects of film producing and stripping, and it can be used for the recycling of residual film in the cotton fields of Xinjiang, it can also provide design reference for residual film recycling machine.
