Locking tooth structure of rear baffle of coal charging car

The utility model relates to the technical field of coal charging cars, in particular to a coal charging car rear baffle locking tooth structure which comprises a compartment, a matched rear baffle is arranged on one side of the compartment, first rotating blocks are fixedly connected to the tops of the two sides of the rear baffle, and rotating shafts are fixedly connected to the opposite sides of the two first rotating blocks. The coal charging car overcomes the defects in the prior art, through the arrangement of the rack, the second gear and the rotating shaft, the rotating shaft and the first gear can be driven to rotate when the unloading oil cylinder of the coal charging car pushes the carriage to rotate with the rotating shaft as the axis, and the first gear can drive the rack to move upwards when rotating. When the rack moves upwards, a second gear can be driven to rotate, when the second gear rotates, a third gear, a rotating shaft and a first rotating block can be driven to rotate reversely, and th
