Although the benefits of the mulching film are great, the white pollution caused by the mulching film is also great, the composition of the mulching film is polyethylene, the natural degradation is extremely long, and the residual mulching film can damage the soil structure and hinder the water migration. In recent years, mechanical mulching film recovery is mainstream, the treatment mode of mechanical mulching film recovery mainly comprises centralized landfill and incineration, secondary pollution is directly caused to the land and the environment, and the recycling of the mulching film cannot be realized. The mulching film is a recyclable material, and because the impurity content of the machine-harvested mulching film is high and the mulching film is seriously wound and knotted with impurities such as cotton stalks and the like, the mulching film is difficult to separate from the cotton stalks by the traditional method. Only when the separation of the mulching film and the cotton stalk is realized, the mulching film can be recycled.
At present, in order to realize the recycling of mulching films, the mulching films are separated from cotton stalks by adopting a manual sorting mode, but large-area popularization cannot be realized due to high-strength labor amount and high cost, and the tying is especially unfeasible when knotted film stalk mixtures are faced. Therefore, in order to realize the separation of the mechanical mulching film collecting mixture and the recycling of the mulching films, the development of a device for efficiently separating the mulching films from the cotton stalks is indispensable.
