[0054] Start the motor 41. The motor 41 drives the first threaded rod 42 and the second threaded rod 45 to rotate synchronously. Under the drive of the thread and the guiding and limiting of the first chute 461, the first slider 43 moves along the axial direction of the first threaded rod 42, and the second slider 44 moves along the axial direction of the second threaded rod 45.

[0057] Start the motor 41 to rotate in the reverse direction. Under the drive of the drive assembly 4, it drives the moving top plate 53 to slide forward into the placing protection box 2, and the moving bottom plate 63 and the prefabricated building materials slide backward into the placing protection box 2, so that each first partition 54 and each second partition 62 are docked up and down, dividing the placing protection box 2 into several placing spaces, and the prefabricated building materials are located in the placing spaces, completing the feeding process. The reverse movement of the drive assembly 4 is the same as the forward movement away from it, only the movement direction is opposite, so it will not be elaborated here.

[0058] Construction workers can move the entire device and the prefabricated building materials to the construction position by pushing the handrail 1 and the universal wheel 9. Start the motor 41 again, so that the drive assembly 4 drives the moving top plate 53 to move backward out of the placing protection box 2, and the moving bottom plate 63 and the prefabricated building materials move forward out of the placing protection box 2, facilitating the removal of the prefabricated building materials and completing the discharging process.
