[0032] like Figures 1 to 8 As shown in the figure, this embodiment provides a wall drilling device for construction projects. This wall drilling device for construction projects includes an electric drill 1, a handle 2 fixedly connected to the bottom of the electric drill 1, and a switch provided on the handle 2. Figure 1 As shown, a drill bit 3 is installed at one end of the electric drill 1;

[0033] A transparent cover 4 is fitted over the outer surface of the electric drill 1. The drill bit 3 is located inside the transparent cover 4. A collection hole 5 is provided inside the transparent cover 4. The collection hole 5 is conical. A dust collection pipe 6 is fixedly connected to the bottom of the transparent cover 4. The dust collection pipe 6 communicates with the inside of the transparent cover 4 through the collection hole 5. Auxiliary pipes 7 are fixedly connected to both sides of the dust collection pipe 6. The two sets of auxiliary pipes 7 correspond to each other. A dust collection tank 11 is installed at the bottom of the dust collection pipe 6. The conical collection hole 5 can facilitate the concentrated flow of dust into the dust collection pipe 6. The transparent cover 4 can facilitate the collection of dust and prevent dust from being inhaled into the respiratory system of the workers. At the same time, the transparent cover 4 can facilitate the workers to observe the drilling progress and the amount of dust. The dust collection tank 11 can facilitate the collection of dust for centralized treatment.

[0034] Both sets of auxiliary pipes 7 are equipped with motors 8. The output end of the motors 8 is fixedly connected to an impeller 9 in a ring array. The auxiliary pipes 7 are also fixedly connected with filters 10, which are located on one side of the impellers 9. The filters 10 prevent dust from directly entering the auxiliary pipes 7. When working, the motors 8 convert electrical energy into mechanical energy. The rotating output end drives the impellers 9 to work, so as to generate suction and draw air and dust into the dust collection pipe 6 through the collection hole 5. When the impellers 9 rotate, they create a low-pressure area, and air and dust are quickly drawn into the dust collection pipe 6 and finally flow into the dust collection tank 11 to facilitate dust collection. With the cooperation of the two sets of motors 8, the overall suction of the impellers 9 can be increased.

[0035] The ash collection pipe 6 has a threaded groove 13 inside, located at the bottom of the ash collection pipe 6. The top of the ash collection tank 11 is fixedly connected to an external thread 12, which is located inside the threaded groove 13 and threadedly connected thereto. This allows the ash collection tank 11 to form a detachable structure, facilitating the handling of collected dust. Simultaneously, if... Figure 7 As shown, the position of the threaded groove 13 can prevent dust from adhering to the external thread 12 and the threaded groove 13.

[0036] A movable plate 14 is movably sleeved on the outer surface of the electric drill 1. The movable plate 14 is located on one side of the transparent cover 4. A nut 15 is fixedly connected to the side of the movable plate 14 away from the transparent cover 4. There are two sets of nuts 15, which correspond to each other.

[0037] The top and bottom of the transparent cover 4 are fixedly connected to connecting blocks 16. Bolts 17 are movably connected inside the connecting blocks 16. One end of the bolt 17 passes through the connecting block 16 and extends to the other side of the movable plate 14 and is threadedly connected to the nut 15. The nut 15 and the bolt 17 correspond one to one, which can connect the transparent cover 4 and the movable plate 14, which facilitates the drilling operation of the drill bit 3 and can increase the drilling depth of the drill bit 3.

[0038] Arc-shaped grooves 18 are provided on both sides of the electric drill 1, and guide grooves 19 are provided on the top and bottom of the electric drill 1. A circular plate 20 that matches the arc-shaped groove 18 is fixedly connected to the inner side of the moving plate 14. A guide block 23 that matches the guide groove 19 is also fixedly connected to the inner side of the moving plate 14. The circular plate 20 is located on both sides of the moving plate 14, and the guide block 23 is located on the top and bottom of the moving plate 14. This can prevent the moving plate 14 from being disconnected from the electric drill 1, thereby facilitating the movement of the transparent cover 4.

[0039] A positioning plate 24 is installed at the end of the electric drill 1 away from the drill bit 3. Positioning blocks 25 are fixedly connected to both sides of the positioning plate 24. Locking blocks 26 are fixedly connected to the top and bottom of the positioning plate 24. The positioning blocks 25 are located at one end of the arc groove 18, and the locking blocks 26 are located at one end of the guide groove 19. This can facilitate sealing the arc groove 18 and the guide groove 19, and at the same time provide support for the tension spring 21 and the telescopic rod 22.

[0040] Telescopic rods 22 are fixedly connected to the inner sides of both sets of circular plates 20. Tension springs 21 are sleeved on the outer surface of the telescopic rods 22. The other end of each telescopic rod 22 abuts against the positioning block 25. The two ends of the tension springs 21 abut against the circular plate 20 and the positioning block 25 respectively. The tension springs 21 and the telescopic rods 22 are both located inside the arc grooves 18. The two sets of tension springs 21 and telescopic rods 22 correspond one-to-one with the two sets of arc grooves 18. The telescopic rods 22 can prevent the tension springs 21 from getting tangled. The tension springs 21 can make the moving plate 14 and the transparent cover 4 elastic, which facilitates the deep drilling operation of the drill bit 3.

[0041] A connecting plate 27 is installed inside the positioning plate 24. A plug 28 is fixedly connected to one end of the connecting plate 27. A screw 29 is rotatably connected inside the connecting plate 27. The screw 29 is located on one side of the plug 28.

[0042] The electric drill 1 has a positioning hole 30 and a threaded hole 31 at the end away from the drill bit 3. The positioning hole 30 is located on one side of the threaded hole 31. One end of the plug 28 passes through the positioning plate 24 and extends into the interior of the electric drill 1 to be movably connected to the positioning hole 30. One end of the screw 29 passes through the positioning plate 24 and extends into the interior of the electric drill 1 to be threadedly connected to the threaded hole 31, so as to fix the positioning plate 24. By fixing the positioning plate 24, the tension spring 21 can be positioned. By disassembling the positioning plate 24, the tension spring 21 can be easily inspected and replaced.

[0043] When in use, the operator holds the electric drill 1 with handle 2, then aligns the drill bit 3 with the area to be drilled, while the transparent cover 4 is placed on the wall. The operator then turns on the switch to start the drill bit 3. The dust generated during the drilling process falls directly into the interior of the transparent cover 4. At the same time, the two motors 8 are activated to drive the impeller 9 to rotate, generating suction. The dust is then sucked into the dust collection pipe 6 through the collection hole 5. The dust then falls into the dust collection tank 11 through the dust collection pipe 6. This completes the purpose of collecting dust and also prevents the dust from flying around and being inhaled into the respiratory system by the operator.

[0044] After drilling is completed, the dust collection tank 11 can be rotated in the opposite direction to make the external thread 12 rotate, so that it is disconnected from the thread groove 13. Finally, the dust collection tank 11 can be disassembled to facilitate the centralized treatment of the collected dust.

[0045] When it is necessary to insert the drill bit 3 into the wall, the drill bit 3 can be inserted into the wall by pushing the handle 2. The other hand can hold the dust collection pipe 6 to facilitate the positioning of the dust collection pipe 6. At the same time, when the drill bit 3 is inserted, the transparent cover 4 is against the wall and slides along the outer surface of the electric drill 1 via the moving plate 14. The tension spring 21 can be squeezed to generate deformation, which facilitates the drilling operation on the wall.

[0046] When the tension spring 21 is damaged or has insufficient elasticity, the screw 29 can be turned in the opposite direction to disconnect it from the threaded hole 31. Pulling the screw 29 will cause the connecting plate 27 and the plug 28 to move away from the positioning plate 24 and separate the plug 28 from the positioning hole 30, thus disassembling the tension spring 21 and facilitating its maintenance and replacement.

[0047] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
