The invention relates to a coal leveling bar with a vibrating compacting function. At least one group of vibrating compacting devices are mounted on the coal leveling bar in the longitudinal direction; each vibrating compacting device comprises a pneumatic vibrator and a compacting plate, and the compacting plate and the coal leveling bar are mounted in the same direction; three hinged supports are longitudinally arranged on each compacting plate, one hinged support is hinged with one end of a connecting rod I, the other end of the connecting rod I is hinged with a piston rod of the corresponding pneumatic vibrator, the other two hinged supports are hinged with one end of a connecting rod II and one end of a connecting rod III respectively, and the other end of the connecting rod II and the other end of the connecting rod III are hinged with the coal leveling bar. The vibrating compacting devices are arranged on the coal leveling bar, the pneumatic vibrators promote the compacting plates to vibrate, a four-bar mechanism promotes the compacting plates to perform vertical patting motions, the purpose of compacting of a coal cake at the top of a top-mounted coking furnace is achieved, the practical use effect is good, the yield of coke of a single furnace is increased, and the coke quality is improved.
