The utility model discloses a blast furnace iron ore material level detection device, used for conveniently and accurately detecting the status data of cloth without affecting the working continuity of blast furnace cloth. The material level detection device comprises a battery pack, a connecting cord, an indicator lamp, a magnetic bead and a magnetic switch; by virtue of the battery pack, the magnetic switch, the magnetic bead and the indicator lamp are serially connected to form a circuit through the connecting cord; the magnetic bead is hung above the magnetic switch perpendicularly; a circuit is conducted and the indicator lamp is constantly turned on as the magnetic bead is connected to the magnetic switch; when the magnetic bead passes through a juncture between an ore powder layer and a coke layer, the magnetic bead, affected by surrounding magnetic field, is deflected and is disconnected to the magnetic switch, at which time the circuit is disconnected and the indicator lamp is turned off, and a mark is made on the connecting cord; the magnetic field disappears and the magnetic bead resets when the magnetic bead enters the coke layer once again, so that the circuit is conducted and the indicator lamp is recovered to the state of being constantly turned on, and a mark is made on the connecting cord; therefore, the thickness of the ore powder layer can be obtained by measuring a distance between the two marks.
