In order to solve the problem of poor profiling effect, easy congestion, stubble lifting, and unsatisfactory film unloading performance of the existing collector machine for corn whole plastic film mulching on double ridges, the improved design of film lifting, film rolling device and the transmission scheme of the machine were carried out. The film lifting device consisted of eight profiling film lifting monomers, slider, guide rail and pressure regulating spring, which can be profiled up and down with the terrain, and solved the problems of stubble lifting, congestion and impact vibration. The film rolling device was composed of main and subordinate moving cone-shaped film rolling roller, the auxiliary film rolling teeth and the linkage film unloading rotating arm. Among them, the film rolling roller was applied as the constant linear speed mechanism of friction transmission to ensure the uniform tightness of the film rolling. The auxiliary film rolling teeth were inserted on the main and subordinate moving film rolling roller by the fast insertion mechanism to realize the efficient winding of the residual film. The main and subordinate moving film rolling roller was designed as the cone-shaped structure to facilitate film unloading. The linkage film unloading rotating arm can ensure that the main and secondary cone-shaped roll were separated approximately in a straight line, which made the film unloading easier and faster. By analyzing the movement of eccentric telescopic elastic teeth, it was determined that the number of circumferential distribution of elastic teeth was 4. Taking the orthogonal test as the optimization design method, the recovery rate, winding rate and impurity content rate of the residual film as the evaluation index, the optimal working parameters of the prototype were obtained by using the comprehensive balance method, which was the forward speed of 3km/h, the rotation speed of the eccentric retractable elastic tooth take-up drum was 60r/min, and the rotation speed of the film roll was 90r/min. The field test was carried out with the optimal working parameters. The test results showed that the recovery rate of the residual film of the machine was 89.46%, the wrapping rate was 1.93%, and the impurity rate was 25.53%. The result met the technical requirements of the collector for corn whole plastic film mulching on double ridges and can provide a reference for the design of the residual film recovery machine.
