Description
Technical Field

Since the introduction of the technology into China in the 70 th of the 20 th century, the technology is widely applied to agricultural production activities, and the development of the agricultural production activities is accelerated. However, with the increasing of the covered area of the mulching film, the residual mulching film in the field seriously influences the soil structure, so that a residual film isolation layer is formed between the soil surface and the plough layer, and soil hardening and crop necrosis are caused.
In contrast, China develops a plurality of efficient residual film recycling machines, and the machines are typically of rod tooth type, sprocket tooth type, telescopic rod tooth type, rake type and the like. The machine tool is generally composed of a film lifting mechanism, a film picking mechanism, a film stripping mechanism, a mold unloading mechanism and the like. Through research, most of the existing residual film recycling machines pay attention to the research of a residual film picking part, and the problem of post-treatment of the residual films is ignored. For example, the residual films recycled by the existing machine type are loose in pile and large in occupied space, which not only causes inconvenience for loading, unloading, pulling and storing of the subsequent residual films, but also causes environmental pollution because the loose residual films are easy to scatter with wind. In order to solve the problems, domestic scientific researchers design a round-bundle type residual film bundling machine according to the principle of a foreign fixed type straw bundling machine, and a bundling system is multiple in parts and high in failure rate. In addition, some researchers also design a square packer based on a hydraulic system, and the machine type works as an independent mechanism, cannot be loaded on a common plastic film residue recycling machine, and is not beneficial to research and development of composite machines.
