Abstract

Provided is an active-passive dual overload disengagement mechanism for a mower blade. The active-passive dual overload disengagement mechanism for a mower blade includes a blade holder and a control rod, where the blade holder is configured to connect an output shaft of a drive motor to the mower blade in a transmission manner, and release a transmission state between the output shaft of the drive motor and the mower blade when the mower blade impacts against a hard obstacle. According to the present invention, the mower blade is an external sheet structure. Blades of two mower blades are provided symmetrically, and can cut a tough weed. The control rod includes one end connected to the blade holder, and the other end connected to a servo motor. The servo motor can drive the control rod to move the blade holder to a preset position.
