The invention discloses an ultrasound vibrating sand mixer which comprises a supporting mechanism, a box body, a stirring device, a driving device and a control device. An ultrasonic transducer is arranged in the driving device. An ultrasonic controller is arranged in the control device. The two ends of the ultrasonic transducer are connected with the stirring device and the ultrasonic controller respectively. According to the ultrasound vibrating sand mixer, the ultrasonic transducer is arranged in the driving device, energy generated by ultrasounds is converted into kinetic energy through the ultrasonic transducer, and the problem of sand adhesion can be well solved; the uniformity of mixing of sand is greatly improved through continuous vibration of the ultrasounds during machining; meanwhile, equipment is controlled through the ultrasonic controller in the operating process, intelligent control over the equipment is achieved, the using stability of the equipment is improved, and accordingly the equipment can better meet production requirements.
