[0002] The rapid and continuous development of the construction industry has led to an increasing degree of mechanization in construction. Therefore, the research, development and application of construction machinery and equipment are of great significance to the construction industry. In construction, walling is the most important project. The traditional walling method basically relies on human hands to complete the huge walling work, and the mechanical equipment used for construction is relatively backward. Therefore, it takes a lot of time and energy to complete the walling work, which leads to high construction investment, long construction period and low construction efficiency. As the wall rises during the walling process, it is necessary to manually lift the blocks onto the scaffolding, which consumes a lot of physical energy for the workers, and the work away from the ground is dangerous, which may cause casualties and pose serious safety hazards. In addition, with the increasing shortage of labor, the new generation of workers are generally unwilling to engage in construction work that requires strong physical labor. Therefore, the development of a wall-building machine is an inevitable choice for the decreasing number of migrant workers in society and a development trend of the construction industry.

When the brick slides down from the load-bearing plate 23, it can be buffered to prevent the brick from being damaged and reducing the performance of the product.

[0055] It should be noted that the combination of the first worm 115 and the first worm wheel 116 is fixed on the base 11 by threaded connection, and a gasket is placed in the middle to prevent the lubricating oil from leaking and polluting the atmosphere.

[0056] A wall-building method based on an automatic wall-building machine comprises the following steps:

[0057] S1: Start the first motor 120, the first motor 120 drives the first transmission mechanism to rotate, the first transmission mechanism transmits power to the lead screw 117, the up and down movement of the lead screw 117 drives the top mechanism above the base 11 to rise and fall, so that the transport unit installed on the top mechanism 12 is raised and lowered;

[0058] S2: Bricks are placed on the turntable 21, and the second motor 27 is started. The second motor 27 transmits power to the second worm gear assembly 28, and the second worm gear assembly 28 drives the turntable 21 to rotate. The turntable 21 transports the bricks to the load-bearing plate 23 through the conveyor belt 22. After the bricks completely enter the load-bearing plate 23, the bricks will slide onto the conveyor 24 driven by their own gravity. The conveyor 24 transports the bricks to the predetermined position and aligns the bricks along the wall under the rotation of the fan blades 26;

[0059] S3: After the bricks are aligned, the cement spraying fixing unit 3 is started, and the nozzle clamping device 32 is controlled to move by the mechanical arm 31, driving the cement pump to move to a distance of 5 cm from the bricks to be laid, and the cement pump is started to spray cement on the surface of the bricks.

[0060] The working principle of the device of the present invention:

[0061] When the device of this aspect is working, the first motor 120 on the base 11 drives the first transmission gear 111 to rotate, and the second transmission gear 112 rotates in coordination with the first transmission gear 111, and transmits power to the first worm 115 through the transmission shaft 113. The first worm 115 will drive the first worm wheel 116 to rotate together, and the rotation is transmitted to the lead screw 117 on the coupling 119 through the shaft installed by the first worm wheel 116. The lead screw 117 cooperates with the nut 118, so that the nut 118 can rise or fall, thereby realizing the lifting and lowering of the top working platform 122, so that the transport unit 2 installed on the top working platform 122 reaches the target position. The power input of the transport unit 2 is provided by the second motor 27, and the second motor 27 transmits power to the second worm gear assembly 28, and the second worm gear assembly drives the rotating shaft 29 to rotate, thereby realizing the rotation of the turntable 21. Bricks are placed on the turntable 21 and transported to the load tray 23 by the conveyor belt 22. After the bricks completely enter the load tray 23, the outer side of the load tray 23 is pressed forward by its own weight, and the bricks will slide onto the conveyor 24, and finally fall to the predetermined output position due to its own weight. After the bricks reach the predetermined position, the cement nozzle will spray cement on the surface of these bricks at a distance of about three or four bricks (30cm) from the bricks being laid. Because there is a certain gap between the bricks, and the spraying range of the cement nozzle is large, the outer surface of the bricks will eventually be covered with cement, which also ensures the laying of the next layer of bricks.
