| Abstract: |
| Aiming at the problem of congestion caused by the accumulation of soil and debris in the forward direction of the unit during the operation of the existing residual film pickup machine, in order to reduce the working resistance, the “open\|hold” style of including rocker device and pickup device was designed using the resistance among the picking teeth, the soil, and the spring tension to the residual film pick\|up machine, the residual film was picked up only by the tractor to adapt to the tractor’s forward speed.The force analysis and kinematics analysis of the pick\|up teeth determined that the diameter of the pick\|up teeth was 15 mm, the number of circumferential arrangements was 14 and the axial distance was 140 mm; the track shape were determined by analyzing the closing process of the picking teeth. Field tests showed that the film pick\|up rate reached 86.40% when the machine operating speed was 5.15 km·h-1, the soil depth was 8.49 cm, and the holding distance was 7.61 cm. The research results helped to solve the problem of residual film pollution in cotton fields and enrich the design theory of residual film recovery machinery. |
