Description

Technical Field

[0001] The present application relates to the technical field of plastic mulch film recycling, and in particular to a plastic mulch film recycling device. Background Art

[0002] Plastic mulch is a covering material widely used in agricultural production. It is mainly made of polymer compounds such as polyethylene and polyvinyl chloride. It has the characteristics of being light, durable, light-transmitting and reflective, and heat-insulating and moisture-retaining. Due to the non-degradable nature of plastic mulch, old plastic mulch needs to be recycled after use. In the existing technology, the recycling method for waste plastic mulch usually uses mechanical rollers to pull the mulch out of the soil and wrap it. Since the surface of the mulch is easily contaminated with soil, on the one hand, it causes inconvenience in the later recycling and processing of the mulch, and on the other hand, it also causes the loss of farmland soil, so it needs to be improved. Summary of the Invention

[0003] In order to improve the problem that plastic mulch films are easily carried with soil during recycling, the present application provides a plastic mulch film recycling device.

The moving mechanism drives the roller mechanism to move to the end of the ground film conveyor belt, thereby rolling up the ground film. After that, the roller mechanism will move further. Under the action of the blower, the soil on the ground film will fall into the mud trough. After the soil has fallen, the roller mechanism continues to move and comes to the top of the recovery trough. The roller mechanism rotates to adjust the angle, so that the ground film falls into the recovery trough and the recycling is completed.
