AI Technical Summary
The film cutting mechanism of existing agricultural mulching equipment is prone to "broken threads" during the cutting process, resulting in poor cutting effect and requiring manual secondary processing.
A film cutting mechanism was designed, comprising a lifting component, a cutting component, and a pressing component. The cutting plate is hydraulically driven to flip and pull the film, while the film is fixed by pressing rollers, thus achieving a combination of vertical shearing and pulling actions to improve the cutting effect.
This effectively avoids the "broken threads" phenomenon that still exists after film cutting, improves the efficiency and effect of film cutting, and reduces manual intervention.
