Roadbed filling quality detection device

The utility model discloses a roadbed filling quality detection device, and relates to the technical field of road engineering. The device comprises a mounting plate, an ultrasonic detector and an electric push rod, the upper end face of the mounting plate is fixedly connected with the ultrasonic detector, the mounting plate is connected with a sleeve through a vertical rod, the mounting plate is connected with a bottom plate through a telescopic rod, and the bottom plate is connected with the electric push rod through a side plate. By arranging the electric push rod, the connecting line can be driven to move downwards, so that the probe is attached to the ground for detection, the labor intensity and the fatigue degree of workers are reduced, a buffering effect is achieved through the spring, the situation that the mounting plate crushes the probe under the action of the electric push rod is avoided, and the fan is arranged, so that the working efficiency is improved. According to the ultrasonic detector, he
