The invention relates to a tracking type coal bunker material level measurement device and belongs to the technical field of automatic detection and measurement. The tracking type coal bunker material level measurement device is characterized in that the continuous coal bunker material level automatic measurement device consists of a probe 1, a transmission system and a measurement system; the probe 1 is a metal cone hollow body; the whole metal cone hollow body is filled with epoxy resin; an upper limit sensor 2 and a lower limit sensor 3 are mounted inside the metal cone hollow body; the upper limit sensor 2 and the lower limit sensor 3 are reflection infrared photoelectric proximity switches integrating transmitters with receivers; when a material level in a coal bunker is changed, switching value signals output by the upper limit sensor 2 and the lower limit sensor 3 are transmitted to a material level intelligent meter 11 through an electric cable 4; the transmission system consists of a steel wire rope 5, a pulley 6, a motor 7, a speed reducer 8 and a steel wire rope roller 9; and the measurement system consists of a coding sensor 10 and the material level intelligent meter 11. The tracking type coal bunker material level measurement device has the advantages of high measurement precision, long service life and continuous dynamic tracking measurement and is mainly used for measuring the material level of the coal bunker of a coal mine, a coal washery and a power station.
