The China is a large agricultural country, the mulching film is very widely used, and the problems are increasingly revealed along with the large-scale application of the mulching film covering technology: waste mulch film is difficult to recycle and has low recycling rate. The global mulching film consumption is 74% in China, and the problem of recycling waste mulching films is to be solved. The application of the novel machinery and the novel technology of the agricultural residual film provides a foundation for recycling the agricultural residual film, and improves the enthusiasm of vast growers for recycling waste films. However, due to the limitation of recycling technology and mechanical equipment, the recycled mulching film contains a large amount of impurities such as soil, stones and crop straws, and the waste mulching film accounts for less than 10%, so that the recycled waste mulching film cannot be recycled further.

At present, the existing mixed waste mulch separating equipment mainly adopts a multi-stage drum screen and multi-stage winnowing mode, and has the problems of low separation efficiency, high energy consumption and high cost, so that the capacity of large-scale treatment and recovery of waste mulch is limited, and the waste mulch recovery of farmers is insufficient in enthusiasm and cannot be popularized; the waste mulch film mixture recovered from cotton fields can contain floor cotton (cotton which is not fully opened and cotton which is not completely collected after being picked by a cotton picker is discarded in the ground to become floor cotton), the floor cotton can be recovered and reused, the existing separation equipment only aims to obtain waste mulch films, cotton is directly discarded along with other impurities after separation, cotton waste can be caused, or a large amount of cotton remains in the waste mulch films obtained after separation, so that the recovery and reuse rate of the waste mulch films is reduced.
