A mortar nozzle device comprises a spraying cavity. A mortar inlet is formed in one end of the spraying cavity. The spraying cavity comprises a first inner spraying cavity body, a second inner spraying cavity body and an outer spraying cavity body. The outer spraying cavity body wraps the second inner spraying cavity body which wraps the first inner spraying cavity body. The cross sections of the first inner spraying cavity body, the second inner spraying cavity body and the outer spraying cavity body are circular. A nozzle gap is formed in the outer spraying cavity body. First nozzle holes are formed in the first inner spraying cavity body and arrayed in the inner spraying cavity body at equal intervals. The areas of the first nozzle holes gradually increase from one side of the mortar inlet to the bottom of the spraying cavity. Second nozzle holes are formed in the second inner spraying cavity body and are equal in hole area. By means of the mortar nozzle device, mortar arrives at the second inner spraying cavity body and then the outer spraying cavity body after passing through the first inner spraying cavity body, the content of mortar at the mortar inlet is compensated for, the content of mortar in the whole spraying cavity is uniform, and mortar is evenly sprayed.
