The invention provides a material receiving device of fireproofing bricks. The material receiving device of the fireproofing bricks comprises a left front supporting plate, a left rear supporting plate, a right front supporting plate and a right rear supporting plate, a left front gear, a left rear gear, a right front gear and a right rear gear are correspondingly arranged on the left front supporting plate, the left rear supporting plate, the right front supporting plate and the right rear supporting plate, a front chain is arranged on the left front gear and the right front gear in a sleeving mode, and a rear chain is arranged on the left rear gear and the right rear gear in a sleeving mode. A feeding mechanism and a material receiving mechanism are arranged between the front chain and the rear chain in sequence in the transferring direction of a base plate, the feeding mechanism comprises a left placing plate, a right placing plate and a feeding air cylinder, and the receiving mechanism comprises a base supporting plate and a supporting air cylinder. The material receiving device of the fireproofing bricks has the beneficial effects that the feeding mechanism and the material receiving mechanism play an automatic feeding role on the base plate; and meanwhile, when the fireproofing bricks are received, the feeding mechanism and the material receiving mechanism play roles of automatic rotating and automatic stacking, and more convenience is achieved.
