Starting the motor 4 drives the screw 41 to rotate, which in turn drives the slide 51 to slide vertically at a uniform speed along the slide bar 42, allowing the spray pipe 2 to spray mortar on the small concrete wall in the vertical direction.

[0025] like Figure 3 As shown, the clamping assembly 5 is arranged inside the frame 3, and the clamping assembly 5 includes a slide 51, a sleeve 52 and a fastening bolt 53. The slide 51 is threadedly connected to the screw 41, the sleeve 52 is fixed inside the slide 51, and the nozzle end of the spray tube 2 is fixed inside the sleeve 52. Multiple groups of fastening bolts 53 are arranged on the peripheral side of the sleeve 52. The nozzle end of the spray tube 2 is inserted into the interior of the sleeve 52, and the multiple groups of fastening bolts 53 arranged on the peripheral side of the sleeve 52 are turned so that the end of the fastening bolt 53 moves toward the interior of the sleeve 52, thereby firmly fixing the spray tube 2 to prevent the spray tube 2 from detaching from the sleeve 52 during mortar spraying operations.

[0026] like Figure 2 and Figure 4 As shown, the transverse movement mechanism 6 is arranged on one side of the frame 3, and the transverse movement mechanism 6 includes a driving assembly 61 and a clamping assembly 62. The driving assembly 61 is arranged on one side of the frame 3, and the driving assembly 61 includes a side seat plate 611, a second motor 612 and a roller 613. The side seat plate 611 is fixed on the frame 3, and the second motor 612 is fixed to the lower end of the side seat plate 611 parallel to the frame 3.

The upper end of the stud 621 is threadedly connected to the limiting sleeve 6211. The size of the limiting sleeve 6211 is larger than the size of the slide groove 6112. The stud 621 is pushed to slide along the slide groove 6112. When the splint 623 contacts the top of the wall of the concrete short wall, the limiting sleeve 6211 is tightened. The limiting sleeve 6211 and the fixed end of the lower end of the stud 621 clamp the stud 621, thereby limiting the position of the splint 623, so that the splint 623 and the side seat plate 611 are respectively clamped on both sides of the concrete short wall.

When the clamping plate 623 contacts the top of the wall of the concrete small wall, the limiting sleeve 6211 is tightened. The limiting sleeve 6211 and the fixed end of the lower end of the stud 621 clamp the stud 621, thereby limiting the position of the clamping plate 623, so that the clamping plate 623 and the side seat plate 611 are respectively clamped on both sides of the concrete small wall, and the nozzle end of the spraying pipe 2 is inserted into the interior of the pipe sleeve 52. The multiple sets of fastening bolts 53 arranged on the side of the pipe sleeve 52 are screwed so that the end of the fastening bolt 53 moves toward the interior of the pipe sleeve 52, thereby firmly fixing the spraying pipe 2. To avoid the spraying tube 2 from detaching from the tube sleeve 52 during the mortar spraying operation, the starting motor 1 4 drives the screw 41 to rotate, and then drives the slide 51 to slide vertically at a uniform speed along the slide rod 42, so that the spraying tube 2 can spray mortar on the concrete small wall in the vertical direction, and the starting motor 2 612 can drive the roller 613 to rotate horizontally, so that the frame 3 moves horizontally at a uniform speed, so that the spraying tube 2 can spray mortar on the concrete small wall in the horizontal direction, which can ensure that the concrete small wall is sprayed evenly. After the spraying is completed, the device is removed from the concrete small wall, and it is further leveled manually, and the position where the plywood 623 contacts the top of the wall of the concrete small wall is supplemented with material.
