The utility model discloses a screw driving system of low-speed big torque motor paver, which comprises an engine. The engine is connected with a driving shaft positioned on a transfer case through a coupling. A pump is arranged on the output shaft of the transfer case, and the output end of the pump is connected with the low-speed big torque motor. The low-speed big torque motor is connected with the screw driving mechanism through a chain drive mechanism. The utility model has reliable working performance, and can reduce the pressure of the screw driving system, increase the screw delivery capacity, reduce the rotational speed of the screw driving, increase the height of the screw delivery, and reduce the impact and acceleration of the working of the screw starting. The utility model makes the screw driving system steady and slow start so as to effectively solve the phenomenon of the segregation, improve the ground smoothness and ensure the operational quality of the large paving width.
