| Pointed to the problems of low efficiency, easy to plug, poor recovery and adaptability for the existed residual film pickup machine with the eccentric telescopic rod or suction/blowing type, a new pickup machine for residual plastic film was designed out. This pickup machine was mainly composed by the fork assembly of picking film railings, tapered picking film roller device tooth, frame, retarder and so on. The results by field test have showed that: These operating procedures as picking film, rolling film, compacting film, removing film and collecting film can be completed in one time by this new machine. When the soil water content was reached 17.75%, the pickup rate of residual plastic film can be reached 97.32%. |
