Aiming at the poor film-impurity separation effect in the process of recycling residual film in the cotton field after autumn,the poor film lifting effect and the problem of a single mode of operation,this paper designs a kind of nail tooth belt type pick-up device.The key components of the pick-up device design,to determine the clearing device;on the nail teeth of the trajectory,picking film conditions and picking up the process of residual film force analysis and calculation,to determine the impact of the main parameters of the work of the pick-up device.Dynamic simulation analysis of the nail tooth belt pickup device picking film process,simulation results show that:nail tooth tooth root stress is the largest,the maximum deformation in the tip of the tooth,and the nail tooth picking film movement process of residual film did not fall off.In order to verify the operational performance of the picking device,taking the forward speed of the machine,the input speed of the film picking spike teeth and the belt installation angle as the influencing factors,and taking the residual film recovery rate and the impurity rate as the evaluation indexes,the integrated scoring method was used to carry out a pseudo-level orthogonal test,and to determine the better combination of the working parameters as follows:the forward speed of the machine was 8 km/h,the installation angle of the belt was 90°,and the input speed of the film picking spike teeth was 124 r/min.The optimal parameter combination was verified,and the residual film recovery rate was 91.13% and the impurity rate was 30.78%,which can provide a reference for the optimisation of the subsequent spiked-tooth belt-type residual film recycling machine.
