[0020] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] Please refer to Figures 1-4, Embodiments provided by the present utility model: A wall drilling device includes a frame 1. At the top of the frame 1, a water tank 2 is fixedly installed by bolts for storing clean water. At the top of the water tank 2, a water inlet 3 is opened, and the water inlet 3 is communicated with the inside of the water tank 2, improving the convenience of adding water to the water tank 2. The top of the water inlet 3 can be threadedly connected with an end cover to prevent the water inside the water tank 2 from spilling. Near the top of the water tank 2 on the frame 1, a water pump 4 is fixedly installed by bolts. At the end of the frame 1, a drill bit 7 is rotatably connected. Inside the frame 1, a notch 16 is opened. On the inner side wall of the notch 16, a servo motor 17 is fixedly installed. The output end of the servo motor 17 penetrates through the frame 1 and is fixedly installed at the end of the drill bit 7 through a coupling. Starting the servo motor 17 can drive the drill bit 7 to rotate at a high speed for drilling. A protective cover 5 is sleeved on the outer surface of the drill bit 7. The protective cover 5 is in a horn shape to reduce the range of dust particle dispersion. The protective cover 5 is made of transparent plastic material to facilitate the operator to observe the drilling distance of the drill bit 7. On the inner side wall of the protective cover 5 close to the drill bit 7, two spray nozzles 6 are symmetrically inserted for atomizing clean water. An overflow groove 13 is opened inside the protective cover 5 and is sequentially communicated with the spray nozzles 6. A communication pipe 9 is inserted on the side wall of the protective cover 5, and the communication pipe 9 is communicated with the overflow groove 13. The end of the communication pipe 9 is inserted with a pipe 10. The other end of the pipe 10 is inserted at the water outlet of the water pump 4. The other end of the water pump 4 is inserted with a pipe 11. Both the pipe 11 and the pipe 10 are made of rubber material. The other end of the pipe 11 is inserted at the top of the water tank 2. The pipe 11 penetrates through the top of the water inlet 3 and is inserted at the inner bottom of the water tank 2. Starting the water pump 4 can transport the clean water inside the water tank 2 to the inside of the overflow groove 13 in sequence through the pipe 11 and the pipe 10. The clean water is then atomized by the two spray nozzles 6 and fully combined with the dust particles, thereby realizing dust reduction, reducing the dust content in the air, reducing the dust content inhaled by the construction workers, reducing the damage to the bodies of the construction workers, and improving the safety during construction.

[0022] At the end of the frame 1 away from the drill bit 7, a grille 12 is fixedly installed. The grille 12 is in a grid shape and is fixedly connected with the frame 1 to form an integral structure, facilitating ventilation and heat dissipation. At the bottom of the frame 1, two handles 8 are fixedly installed. Grooves are opened on the side walls of the handles 8, improving the convenience of the construction workers' grasping.

[0023] At the end of the frame 1 close to the drill bit 7, a mounting seat 15 is fixedly installed for the threaded connection of the protective cover 5. The mounting seat 15 is sleeved on the outer surface of the drill bit 7. A threaded groove 14 is opened inside the protective cover 5, and the internal dimensions of the threaded groove 14 are adapted to the external dimensions of the mounting seat 15, improving the stability of the installation of the protective cover 5.

[0024] Working principle: When this kind of wall drilling device is in use, the construction worker first connects to an external power supply, then grasps the outer surface of the handle 8 with both hands in turn. Starting the servo motor 17 can drive the drill bit 7 to rotate at a high speed. When the construction worker presses the high-speed rotating drill bit 7 against the wall surface, drilling construction can be realized. When a large amount of dust is generated due to the high-speed rotation of the drill bit 7, the protective cover 5 is sleeved on the outer surface of the drill bit 7 in a horn shape to reduce the range of dust dispersion. Then, starting the water pump 4 can deliver the clear water inside the water tank 2 to the inside of the overflow tank 13 in turn through the second pipeline 11 and the first pipeline 10. The clear water is then atomized by the two nozzles 6 and fully combined with the dust particles, thereby realizing dust reduction, reducing the dust content in the air, reducing the dust content inhaled by the construction worker, reducing the damage to the body of the construction worker, and improving the safety during construction.

[0025] Secondly, the internal size of the thread groove 14 is adapted to the external size of the mounting seat 15, and the protective cover 5 can be threadedly connected to the outer surface of the mounting seat 15, thereby improving the stability of the installation of the protective cover 5. The protective cover 5 is made of transparent plastic material, which is convenient for the operator to observe the drilling distance of the drill bit 7.
