Description

Technical Field

[0001] The utility model relates to the technical field of residual film recycling equipment, in particular to a film and impurity shredding cutter roller and a shredding device. Background Art

[0002] The ground film, namely the ground covering film, is usually a transparent or black PE film, which is widely used in modern agriculture to keep the soil temperature, reduce water evaporation, inhibit weed growth and increase crop yield. However, the large-scale use of ground film also brings environmental pollution problems.

[0003] Although the existing residual film recycling equipment alleviates the problem of ground film pollution in cotton fields to a certain extent, the impurity content of the ground film after mechanical recycling is relatively high, and "knotting" is serious, that is, the flexible residual film in the form of strips or sheets and the impurities such as woody straws and soil in the form of strips in the residual film mixture after mechanical recycling are tightly wound and wrapped together, resulting in the inability to recycle the ground film and cotton stalks. Therefore, shredding the residual film and cotton stalks and separating the film and impurities, converting the rich cotton stalk resources into high-quality fuels, artificial boards, feeds, etc., and processing the waste ground film into plastic products can turn the machine-harvested residual film mixture into treasure to solve the problem of residual film pollution.

[0004] In the film and impurity shredding technology, the existing shredding cutter roller can shred the film and impurities. However, due to the softness of the film and impurity mixture and the presence of some blocky structures, when the blocky film and impurity mixture enters the shredding component, it is easy to accumulate, jam, and even freeze in the shredding cavity. In addition, the shredded materials are easy to rotate with the cutter roller continuously, resulting in winding around the cutter roller, which also affects the shredding efficiency.
