[0003] Existing construction engineering waterproofing technology often uses a construction engineering waterproofing device disclosed in announcement number CN210738031U, which drives the stirring rod and spiral on the rotating shaft to rotate synchronously through the rotation of the rotating shaft to stir and mix the paint, and then transports the paint to the spray head through pressurization, which is sprayed onto the building surface by the spray head, and the hot air blower outputs hot air to the air nozzle to quickly dry and solidify the sprayed building surface. However, the device does not move at a uniform speed, which will cause uneven spraying of the paint, affecting the appearance and the waterproofing effect. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0022] Reference Figures 1-4 A waterproof device for construction engineering includes a main body 1 equipped with universal wheels, a driving motor 2 is fixedly installed on the top of the main body 1, a central shaft 3 connected to the output end of the driving motor 2 is rotatably installed in the main body 1, and a stirring rod 4 is fixedly installed on the central shaft 3. In order to maximize the waterproof effect of the paint, the stirring rod 4 is rotated to fully mix the paint and the diluent. The paint is relatively viscous and the flow rate of the paint is slow in a static state. The stirring rod 4 controls the movement of the paint to improve the efficiency of spraying.
[0023] A conduit 5 is fixedly installed on one side of the main body 1. A slope for the circulation of paint is provided at the connection between the main body 1 and the conduit 5, and the conduit 5 is located between the bottom surface of the main body 1 and the universal wheel. A spray plate 6 equipped with a nozzle is installed at the free end of the conduit 5. The slope can facilitate the flow of paint into the spray plate 6. A scraper 7 for spreading the paint is installed on the pin shaft of the spray plate 6, and an adjustment mechanism for controlling the state of the scraper 7 is provided on the spray plate 6.
[0024] The adjustment mechanism includes two groups of sliders 8 slidably mounted on the scraper 7. Both groups of sliders 8 are pin-mounted with transmission rods 9 connected to the pins of the spray plate 6. Both groups of transmission rods 9 are L-shaped structures, and the two groups of transmission rods 9 are equidistantly distributed on the spray plate 6. A connecting shaft 10 is fixedly installed between the two groups of transmission rods 9. The free end of the transmission rod 9 is fixedly mounted with a strong spring 11 fixedly connected to the spray plate 6. The strong spring 11 is a part made of elastic material. It is deformed under the action of external force and returns to its original shape after the external force is removed. The strong spring 11 here always has an extension force, and a guide long hole 12 is provided on the transmission rod 9.
[0025] A support rod 13 is welded on the spray plate 6, and a locking hole 17 is provided on the support rod 13. A first connecting rod 14 connected to the pin shaft of the support rod 13 is installed in the guide long hole 12, and a second connecting rod 15 is fixedly installed on the first connecting rod 14. The first connecting rod 14 and the second connecting rod 15 are both U-shaped structures. The second connecting rod 15 is located on the outside of the first connecting rod 14, and a fixing plate 16 is rotatably installed on the second connecting rod 15. A buckle 18 connected to the locking hole 17 is installed on the fixing plate 16. One end of the buckle 18 is in the shape of a cross bar, and the outside of the locking hole 17 is a structure that fits one end of the buckle 18. The inside of the locking hole 17 is in the shape of a circular hole. When the buckle 18 is inserted into the locking hole 17, the strong spring 11 is stretched by external force and exceeds its normal force. At this time, the strong spring 11 will have a contraction force, which makes the buckle 18 have an outward force, thereby controlling the buckle 18 to fit the inner wall of the locking hole 17.
[0026] It should be noted that the specific model and specifications of the drive motor 2 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.
[0027] The functional principle of this utility model can be explained through the following operation modes:
[0028] Place the paint in the main body 1, turn on the drive motor 2, control the central shaft 3 to rotate clockwise, and use the stirring rod 4 to evenly stir the paint. The paint enters the spray plate 6 through the conduit 5 and is sprayed onto the building surface by the nozzle. The paint is then smoothed by the scraper 7 on the building surface. The strong spring 11 is always in a contracted state, controlling the transmission rod 9 to keep rotating clockwise, so that the scraper 7 is always in contact with the building ground.
[0029] When the device is not needed, the buckle 18 is inserted into the locking hole 17 and rotated 90 degrees. At this time, the first connecting rod 14 will swing upward, thereby pulling and driving the transmission rod 9 to rotate counterclockwise, controlling the slider 8 to slide downward, thereby controlling the scraper 7 to rotate clockwise, so that the scraper 7 does not contact the building ground.
[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
