The utility model relates to an electromagnetic speed sensing action device for a coal conveyer apparatus, comprising a sensor and a magnetic line cutting wheel. The sensor is provided with a sensing head, a base, a working head and a signal sensing leading line. The magnetic line cutting wheel is composed of two semi-circle gears which can be folded. Both ends of each semi-circle gear are respectively provided with connecting bosses which are fastened by bolts. The exterior surfaces of the circumferences of the gears are provided with a plurality of magnetic line cutting teeth and the magnetic line cutting rotate along the end surfaces of the working head and the sensing head to cur the magnetic lines. The utility model is non-contact type and has no mechanical wear problem. The electromagnetic speed sensing action device is convenient to be installed and is water-proof by sealing.
