Ultrasonic-assisted static jaw device of jaw crusher

The ultrasonic auxiliary device of the jaw crusher comprises a rack, a motor is fixedly arranged on one side of the rack, the output end of the motor is connected with a belt, the other end of a belt pulley is connected to the belt pulley, the belt pulley is fixed to one end of an eccentric shaft, the eccentric shaft is connected with a movable jaw, and the movable jaw is connected with the motor. A static jaw is fixed to the left side of the movable jaw, lining plates are arranged on the surfaces of the static jaw and the movable jaw, and an ultrasonic machining system is connected to the lining plate of the static jaw and fixed to the rack. According to the utility model, the ultrasonic processing system is additionally arranged on a traditional jaw crusher, so that when the crusher works, except that the movable jaw crushes rocks through reciprocating motion, the static jaw lining plate also has a certain movable space and has an ultrasonic excitation effect on the rocks, so that the working efficiency can
