Description

Combined Cotton Stalk Pulling, Crushing, Field Returning and Surface Residual Film Recovery Combined Operating Machine

technical field

The utility model relates to a combined operation machine for pulling up and crushing cotton stalks and returning them to the field and recovering residual film on the surface.

Background technique

In 1980, the Xinjiang Production and Construction Corps introduced plastic film mulching technology for the first time in cotton planting, and the cotton production increased by more than 35% through the planting test. Mulch film is widely used in cotton planting because of its advantages of increasing temperature and keeping moisture, inhibiting weed growth and increasing cotton yield. At present, the large-scale cotton planting in Xinjiang all adopts plastic film mulching technology. However, the use of a large number of mulch films not only brings significant economic benefits, but also causes serious residual film pollution in cotton fields. Residual film pollution will have a bad impact on cotton growth, cotton production and livestock, and the problem of residual film pollution treatment needs to be solved urgently.

Aiming at the treatment of residual film pollution in cotton fields, some scientific research institutions, colleges and agricultural machinery enterprises have successively developed some agricultural machinery for residual film recovery operations. Because there are still some problems in the currently developed residual film recycling machines, the residual film recycling work mainly depends on manual picking up of residual film to complete. The main factors affecting the mechanical recovery of residual film are that the thin film thickness leads to low strength after weathering and the intensive cotton planting affects the mechanical recovery of residual film.
