Description

Technical Field

[0001] The invention relates to the technical field of film removal during planting, in particular to a film removal mechanism for crop planting. Background Art

[0002] Crop mulch films are thin films used to cover farmland. They are used to increase soil temperature, retain moisture, maintain soil structure, and protect crops from pests and diseases caused by certain microorganisms. After use, mulch films often remain in the fields due to inadequate and incomplete recycling. Mulch films are primarily made of polyethylene (PE), a hydrocarbon compound that is extremely difficult to degrade under natural conditions. Failure to promptly recycle these films not only affects crop growth and development but also pollutes the environment.

[0003] However, when removing mulch, a rake claw is typically fixed to the rear end of the vehicle body, and the vehicle body moves to drive the rake claw to remove the mulch. As the claws remove the mulch, the mulch tends to wrap around the outside of the claws. After each period of operation, the mulch outside each claw must be cleaned sequentially, otherwise it will affect subsequent mulch removal operations. Cleaning multiple claws one by one is cumbersome and can easily cause injury to the operator if not handled with caution. To facilitate scraping off mulch that has wrapped around the claws, a crop planting film removal mechanism is provided. Summary of the Invention
