Abstract
The utility model discloses a scraper plate conveyor and a driving mechanism thereof. The driving mechanism comprises a motor and a speed reducer. The output shaft of the motor is in transmission connection with the input shaft of the speed reducer through shaft couplings. The motor is electrically connected with a vacuum soft-start controller which is used for causing the motor to start smoothly. According to the scraper plate conveyor provided by the utility model, after the motor and the speed reducer in the driving mechanism are connected through shaft couplings, the motor is caused to start smoothly through the vacuum soft-start controller which is connected with the motor, thereby reducing impact to the electric network. Because the vacuum soft-start controller can accurately control the time of the motor between energization start and full-speed operation, the scraper plate conveyor and other sets of equipment can be controlled according to a centralized manner. Interference among different sets of equipment is prevented, and normal operation of coal mine is ensured.
