Description

TECHNICAL FIELD

[0002] Mulch film has the effects of improving ground temperature, water conservation, soil conservation, and fertilizer conservation in agricultural planting, and also has the effects of weed control, disease and pest prevention, drought and flood resistance, salt inhibition, seedling preservation, and improvement of light and heat conditions near the ground, and is widely used. With the development of technology, various cleaning processes and cleaning equipment for waste mulch film have appeared. These equipment and processes aim to improve cleaning efficiency, reduce environmental pollution, and realize the recycling of mulch film.

[0003] Through the team's search, it is found that the traditional mulch film cleaning method is to directly put the mulch film into a friction washing machine, and then the waste mulch film is moved forward by the rotating blades of the separation tank to realize the flow line type mulch film cleaning work. Since straw and dust are easily attached to the mulch film, direct water contact will further cause the mulch film to stick together with these impurities and be difficult to separate, but this way is low in efficiency for cleaning the mulch film, and also wastes a lot of water resources, so the mulch film needs to be pre-cleaned before cleaning, so in order to improve the cleaning and screening efficiency and quality of the mulch film, a mulch film processing system needs to be developed.
