A Seedling Film Recycling Machine

technical field

The utility model belongs to the field of agricultural machinery, in particular to a recycling machine for plastic film at seedling stage.

Background technique

With the needs of people's life, in order to improve the yield and quality of crops, more and more crops are planted with plastic film. If the plastic film left in the field is not cleaned in time, it will affect the planting of the next crops on the one hand, and at the same time, due to the accumulation over the years, it will cause serious pollution to the soil and the environment. Therefore, it is necessary to develop a plastic film recycling machine that can meet the operational requirements.

At present, the mulch recycling machines developed in China mainly include telescopic rod-tooth type, spring-tooth type and gear-tooth type. The retractable rod-tooth type recovery machine has a complex structure and high cost; the spring-tooth type recovery machine has a low film recovery rate and can only collect the film into piles or strips; the gear-tooth type is not suitable for film recovery at the seedling stage. These implements generally have the problems of low plastic film recovery rate, complex structure, and difficult repair, maintenance and cleaning.
