The utility model relates to the technical field of
casting of aluminum
alloy automobile parts, and discloses an automatic slagging-off device of a
melting furnace, which comprises a bottom plate, a rack is fixedly connected onto the bottom plate, a
crank is rotatably connected onto the rack, one end of the
crank is in transmission connection with a power device, and the other end of the
crank is slidably connected into a chute of a grooved connecting rod. A sliding rod is fixedly connected in the length direction of the grooved connecting rod, a guide sleeve corresponding to the sliding rod is arranged on the bottom plate, the sliding rod is connected to the guide sleeve in a sliding mode, and a rake used for slagging off is hinged to the front end of the sliding rod. Automatic slagging-off operation of the
melting furnace is achieved,
body discomfort caused by long-time standing of
slag removal personnel in a high-temperature area is relieved, labor intensity is lowered, the
scalding risk is avoided, the rake head is lifted to be separated from molten aluminum when the rake enters the furnace through the matching effect of the
cam, and the
slag removal efficiency is improved. And when the drag head is pulled back, the drag head descends to cling to the bottom of the furnace to remove
slag, so that the slag removal effect is ensured, and the cleanliness of molten aluminum is improved.
