[0027] In this embodiment, the above-mentioned adjustment mechanism includes a rotating shaft 14, a rotating disk 15, a steering ball 16, a pin rod 17, a guide rod 18 and a round tube 19.

[0028] In this embodiment, a water inlet is provided at the top of the water tank 5, a rubber plug 28 is installed on the inner thread of the water inlet, and a heating resistor 27 is fixedly installed in the water tank 5.

By utilizing the combined effect of the round tube 19 and the bearing seat 9, the mounting block 11 and the nozzle 12 can be turned forward, thereby spraying water on the concrete in the left front of the forward direction. Similarly, when the control turntable 15 rotates counterclockwise (as shown in FIG. 1 ), the turntable 15 drives the right end of the guide rod 18 to rotate backward. By utilizing the combined effect of the round tube 19 and the bearing seat 9, the mounting block 11 and the nozzle 12 can be turned forward, thereby spraying water on the concrete in the left front of the forward direction. Figure 3 As shown), the nozzle turns backward, that is, sprays water to the concrete in the right front direction of the device's forward direction. When the ambient temperature is low and the curing temperature needs to be increased, the heating resistor wire can be controlled to operate to heat the clean water and then spray hot water. While spraying water to the concrete, the motor 24 on the same side of the concrete can be controlled to rotate forward, and the motor 24 drives the first gear 25 to rotate. By utilizing the meshing rotation of the first gear 25 and the second gear 26, the central axis 22 can be tilted toward the concrete, and the central axis 22 is supported by the support block 29. The starting end of the protective film is fixed on the concrete surface, and the device can be controlled to move forward. When the device moves forward, water can be sprayed on the concrete, and then the protective film roll 23 is driven to unfold by the forward movement of the device to protect the concrete, which greatly improves the work efficiency and is suitable for promotion.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
