One end of the wire rope 7 is arranged on the rope collector 2, and the other end is connected with the ultrasonic sensor 10 after bypassing a rope winding wheel 4. In use, the ultrasonic sensor 10 is located at a distance above the material level of the bin, so that the material level in the bin can be measured without contacting with the material, and the accuracy of the measurement of the ultrasonic sensor 10 is affected.
