[0002] With the rapid advancement of China's industrialization and urbanization process, combined with the trend of rural land circulation and the great change of rural land integration (small field to large field), a large number of rural labor force is transferred to the city, young people go out to work, and the old, weak, sick, pregnant and other surplus labor force carry out agricultural production, resulting in the increasingly reduced agricultural production efficiency, the serious shortage of labor force in agricultural production, and the phenomenon of lack of advanced technical equipment in agricultural production, and the existing production and operation mode in rural areas cannot meet the needs of modern agricultural development. Therefore, accelerating the level of agricultural mechanization and improving labor productivity are the urgent problems to be solved for realizing agricultural modernization and promoting the comprehensive and coordinated development of agriculture and rural economy, and are also the objective requirements for improving the level of agricultural material technical equipment and developing modern agriculture in China.
[0003] As an important agricultural material, agricultural mulching film plays an important role in increasing agricultural production and increasing farmers' income. However, in recent years, with the increasing use of agricultural film and the increasing use of agricultural film, the residual film in the plough layer of farmland soil is more and more, and the problem of "white (black) pollution" in local areas is increasingly prominent. The waste agricultural film left in the soil of cultivated land causes serious harm to crop growth, soil ecological environment and village appearance. Therefore, strengthening the recycling, treatment and reuse of waste agricultural film, preventing and treating the "white (black) pollution" of farmland residual film, is of great significance to the protection of cultivated soil environment and the promotion of agricultural green development.
[0004] At present, most of the production activities in agricultural production are carried out with the help of mechanized equipment. However, in many areas, after the harvest of crops, the treatment of farmland residual film still relies on manual operation recycling, even in the farmland film recycling machinery, it is completed by relying on single function recycling equipment, combined with the fact that many agricultural films are easily aged and rotten under long-term sunlight, resulting in poor recycling effect of farmland residual film, low residual film treatment and reuse rate, and very low agricultural production efficiency. Especially in some areas where mechanized operation cannot be implemented (such as mountainous areas, hilly areas, loess plateau and fixed small range agricultural scientific research test area), crop residual film can only rely on manual recycling, and mechanized operation is significantly inhibited.
