Abstract Currently, the treatment of residual film of the farmlands in China has caused serious white pollution,nevertheless,the membrane fragments of residues in soil seriously have affected the country's grain output。The harm of farmland residual film is growing hard increasingly。 Farmland residual film shredding machine is viewed as the carrier of farmland residual film recycling industry in China。It plays a decisive role in the researching and development of farmland residual film recycling projects。 In this papper, we have mainly studied the structure design of the machine, the statics analysis of roller, the main structure of the finite element analyzing checking and the optimization design and analysis, based on working principle and function of the farmland residual film shredding machine。

Firstly,we discuss the domestic and foreign researching present situation of the shredding machine industry and make detailed introduction of the researching course of the counterparts in China, especially the farmland residual film shredding machine。 According to the working principle, working process and functions of the residual film shredding machine ,we have proposed the overall design of the shredding machine and made analysis of its load and stability。

Secondly,we use PROE software to build the 3 d model of main body structure of the roller in farmland residual membrane shredding machine。And Ansys Workbench software is used to make the further comprehensive analysis of the roller,which has included the statics analysis,modal analysis。It also proves that the design of this structure can satisfy the requirement of the machine’s working conditions。 This design is proved to be rational and practical。

Finally, based on the current roller structureand the problems that may occur, we will optimize the structure of roller again。We will create 3d model of the optimized cylinder structure。We will also make the comprehensive finite element analysis of the structure of the optimized roller and make comparison between the the original design and the current conclusion。
