Wall building machine

The invention discloses a wall building machine, which comprises a brick grabbing mechanism, a mortar feeding mechanism and a plastering mechanism. The brick grabbing mechanism, the mortar feeding mechanism and the plastering mechanism are all arranged on an operating platform. The brick grabbing mechanism comprises a first mechanical arm and a brick clamping device; the mortar feeding mechanism comprises a mortar storage tank, a supporting frame and a conveying bucket; the plastering mechanism comprises a second mechanical arm and a plastering plate. The first mechanical arm and the second mechanical arm are both connected to the controller, and a moving mechanism is arranged under the operating platform. By integration of the brick grabbing mechanism, the mortar feeding mechanism and theplastering mechanism, a whole process of feeding, plastering and bricking is completed automatically, simulation of manual wall building action is realized, and accordingly manual participation is sharply reduced, and labor
