Abstract
The invention discloses a mower braking structure, comprising a base. A motor is fixed on the base, and the base is rotatably connected with an output shaft. The output shaft is provided with a belt pulley. The output shaft is in transmission with the motor through a belt. A belt pulley lining is arranged between the belt pulley and the output shaft. The belt pulley lining is fixed with the output shaft. A locking structure is arranged between the belt pulley and the belt pulley lining. With the adoption of the locking structure, the belt pulley can drive the belt pulley lining to rotate when the belt pulley rotates. A spring is arranged between the belt pulley and the belt pulley lining, and also a friction structure is arranged between the belt pulley and the belt pulley lining. After the belt pulley loses power, the spring releases elastic force to lead the belt pulley lining to rotate invertedly relative to the belt pulley, and accordingly the friction structure takes effect. According to the invention, the belt pulley and the belt pulley lining can realize rotation relative to each other for certain displacement. In the rotation progress, bulged parts on the inner side of the belt pulley provide pressure or release pressure for movable friction blocks assembled on the belt pulley lining, and thus, the braking structure is effectively ensured to run reliably. Thus, the mower braking structure has a compact structure, convenience in operation, and a stable and reliable system.
