Description

Technical Field

[0001] The present invention relates to the field of mulch film transportation, recovery and processing with classification numbers B65G, B02C and B29B17, and in particular to an agricultural mulch film raw material air selection, transportation and recovery system and an application method thereof. Background Art

[0002] In agricultural planting, ground film has the effects of increasing ground temperature, retaining water, soil and fertilizer, killing weeds, preventing pests and diseases, preventing drought and waterlogging, inhibiting salt and protecting seedlings, and improving near-ground light and heat conditions. Therefore, it is widely used. With the development of technology, a variety of waste ground film cleaning processes and cleaning equipment have emerged. These equipment and processes are designed to improve cleaning efficiency, reduce environmental pollution, and achieve the recycling of ground film.

[0003] Our team found that the traditional way to clean mulch is to directly put the mulch material into the friction washing machine, and then use the rotating blades in the separation tank to push the waste mulch forward to achieve assembly-line mulch cleaning. Since straw and dust are easily attached to the mulch, direct contact with water will further make the mulch and these materials stick together and difficult to separate. However, this method is inefficient for cleaning mulch, and it also wastes a lot of water resources. Therefore, the mulch needs to be pre-cleaned before cleaning. Therefore, in order to improve the cleaning and screening efficiency and screening quality of the mulch, it is urgent to develop an agricultural mulch processing system. Summary of the invention
