[0020] The other side of the swinging arm 22 is provided with a driving assembly, and the fixed frame 15 is provided with a lifting driving assembly;

[0021] This invention first uses a drive assembly to drive the swing arm 22 to periodically swing around the fixed shaft 21. Simultaneously, a liquid pump 5 and a suction pipe 6 pump the curing liquid from the liquid tank 4 into the spray pipe 28 via a flexible hose, and then inject it into the nozzle 31 through the spray pipe 28. Finally, the liquid is sprayed out through the nozzle 31, thus spraying and curing the concrete. During spraying, the swing arm 22 drives the nozzle 31 to periodically swing, thereby achieving a fan-shaped spraying of the concrete. At the same time, a lifting drive assembly drives the sliding lifting frame 10 to slide and lift, thereby adjusting the height of the nozzle 31. This allows the nozzle 31 to swing and spray while gradually rising and falling, thus achieving uniform spraying of the curing liquid onto the concrete. Simultaneously, the relative position of the nozzle 31 and the swing arm 22 is adjusted via the sliding connection between the adjusting groove 27 and the spray pipe 28, thereby adjusting the swing radius of the nozzle 31. This adjustment is made according to the width of the concrete. Furthermore, the orientation of the nozzle 31 can be adjusted via the rotational connection between the rotating shaft 14 and the sliding lifting frame 10, thus adjusting the spraying angle of the nozzle 31.

[0022] In one instance of this embodiment, please refer to Figs. 1-3 The frame 1 is equipped with wheels 2 at the bottom and push handles 3 at the rear. The present invention enables the frame 1 to move automatically through the cooperation of push handles 3 and wheels 2.

[0023] In one instance of this embodiment, please refer to Figs. 1-3 The other end of the rotating shaft 14 is fixedly connected to a limiting frame 16. Limiting holes 17 are provided on both sides of the limiting frame 16. A fixing frame 15 is fixedly connected to both sides of the sliding lifting frame 10. Threaded cylinders 18 are fixedly connected to both sides of the fixing frame 15. Limiting bolts 19 are provided in the limiting holes 17, and the limiting bolts 19 are threadedly connected to the threaded cylinders 18. This invention first limits and fixes the fixing frame 15 and the limiting frame 16 through the threaded connection between the limiting bolts 19 and the threaded cylinders 18, thereby limiting and fixing the rotating shaft 14 and the sliding lifting frame 10. Axial limiting and fixing are performed between the frame 10. When it is necessary to adjust the orientation of the nozzle 31, simply unscrew the limiting bolt 19 to release the axial fixing between the limiting frame 16 and the fixed frame 15. At this time, the rotating shaft 14 can be rotated to adjust the angle of the nozzle 31. Then, the limiting bolt 19 is inserted back into the limiting hole 17 and tightened into the threaded cylinder 18, thereby clamping and fixing the limiting frame 16 through the limiting bolt 19, and then clamping and fixing the limiting frame 16 and the fixed frame 15 again.

[0024] In one instance of this embodiment, please refer to Figs. 1-3The drive assembly includes a drive groove 23 on the other side of the swing arm 22. A second motor 24 is fixedly connected to the mounting arm 20. A rotating arm 25 is fixedly connected to the output shaft of the second motor 24. A drive rod 26 is fixedly connected to the rotating arm 25. The drive rod 26 is disposed in the drive groove 23. The drive assembly drives the rotating arm 25 to rotate through the second motor 24. The rotating arm 25 drives the drive rod 26 to rotate around the axis of the second motor 24. The drive rod 26 drives the swing arm 22 to reciprocate through the mutual cooperation of the drive groove 23.

[0025] In one instance of this embodiment, please refer to Figs. 1-3 The lifting drive assembly includes a ball screw 11 rotatably connected within the mounting frame 8. A drive cylinder 12 is fixedly connected to the nut of the ball screw 11. The drive cylinder 12 is fixedly connected to the sliding lifting frame 10. A first motor 13 is fixedly connected to the mounting frame 8. The output shaft of the first motor 13 is fixedly connected to the drive end of the ball screw 11. The lifting drive assembly drives the ball screw 11 to rotate through the first motor 13, thereby converting the rotational motion of the first motor 13 into the linear motion of the nut through the ball screw 11. The nut drives the sliding lifting frame 10 to lift and lower through the drive cylinder 12.
