[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] In order to solve the problem that in the prior art, during the actual use of a building wall grooving device, dust reduction is achieved by spraying liquid, but the spraying of liquid will cause liquid to drip, and a large amount of liquid dripping in the corners of the wall will affect subsequent use, and further construction cannot be carried out for a period of time after grooving, affecting the overall construction efficiency. The following technical solutions are provided in this embodiment:

[0024] A building wall grooving device includes a pressing piece 5. A rotatable grinding wheel 10 is arranged inside the pressing piece 5. In the rotating state, the grinding wheel 10 can approach the wall and grooving can be achieved. As Figure 2 and Figure 3 shown, one end of the pressing piece 5 is provided with a first handle 6 for grasping and pushing. By pushing the position of the first handle 6, the grinding wheel 10 can be manually moved towards the wall, move towards the wall and complete grooving.

[0025] In this embodiment, a wrapping frame 4 is arranged outside the pressing piece 5. When the device is not in use, the wrapping frame 4 wraps and protects the internal pressing piece 5 and the grinding wheel 10. The wrapping and protection can prevent external foreign objects from colliding with the grinding wheel 10. As Figure 1 , Figure 2 and Figure 3As shown, hydraulic telescopic rods 2 for pushing are provided at the lower ends on both sides of the wrapping frame 4. A support telescopic rod 3 is provided on one side between the two hydraulic telescopic rods 2. Before the device is used, the horizontal position of the grinding wheel 10 can be pushed by the telescopic movement of the hydraulic telescopic rods 2. And during the pushing and subsequent pressing for grooving, the support is provided by the telescopic movement of the support telescopic rod 3 to prevent the positions of the wrapping frame 4 and the internal grinding wheel 10 from shifting, improving the stability of the device during construction. The lower ends of the two hydraulic telescopic rods 2 and the support telescopic rod 3 are fixedly connected through a base 1. The device as a whole is supported through the base 1, and the universal wheels at the four corners of the lower end of the base 1 can be used to push the device. The user can push the device to the required position;

[0026] In this embodiment, guide frames 11 are provided at the four corner positions inside the wrapping frame 4. Second guide posts 12 for sliding guidance are provided on the guide frames 11 facing the middle position of the wrapping frame 4. As Figure 3 、 Figure 5 and Figure 6 shown, second reserved holes 24 are provided at the four corner positions outside the pressing piece 5, and the inside of the second reserved holes 24 is slidably connected to the external sliding grooves of the second guide posts 12. Through the support of the guide frames 11 and the guidance of the second guide posts 12, the stability during the horizontal pressing of the grinding wheel 10 can be improved;

[0027] In this embodiment, a dust collection block 13 is fixedly provided at the lower end inside the wrapping frame 4. An inclined surface 16 is provided on the dust collection block 13 facing the inside of the wrapping frame 4. The guidance of the dust collection block 13 can prevent the dust cut by the grinding wheel 10 from flowing out after flowing into the inside of the wrapping frame 4, and the inclined surface generated by the inclined surface 16 can prevent the remaining dust from falling into the dust collection bucket 15, facilitating the collection of dust and preventing the dust from flowing out. As Figure 3 、 Figure 5 、 Figure 6 and Figure 7 shown, a dust limiting block 14 is provided at the upper end inside the wrapping frame 4. A limiting arc 17 is provided on the dust limiting block 14 facing the inside of the wrapping frame 4. As the grinding wheel 10 rotates, a part of the particles will be driven to rotate along with the grinding wheel 10. Before the particles rotating with the grinding wheel 10 splash onto the wall surface, they will be restricted by the dust limiting block 14 and retained inside the limiting arc 17 to prevent the particles;

[0028] In this embodiment, as Figure 6 shown, a storage frame 9 is welded and provided at the middle of the lower end of the wrapping frame 4. A dust collection bucket 15 is slidably arranged inside the storage frame 9. The materials collected by the wrapping frame 4 will directly fall into the dust collection bucket 15 and be collected. After the device is used, it can be directly slid out for easy handling and use of the dust particles;

[0029] In this embodiment, a guiding frame 8 is provided at the upper end of the wrapping frame 4, and the guiding frame 8 is fixedly connected to the outer wall of the wrapping frame 4 by bolts. A first guiding column 7 is provided at the upper end of the first handle 6, and the first guiding column 7 is fixedly welded to the first handle 6. As Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the outside of the first guiding column 7 is slidably connected to the internal sliding groove of the guiding frame 8. During the pressing process of the first handle 6, the first guiding column 7 will also be guided by the guiding frame 8, further improving the stability during the pressing and grooving process;

[0030] In this embodiment, a threaded rod 21 is horizontally arranged inside the guiding frame 8. A limiting piece 22 is arranged outside the threaded rod 21, and the inside of the limiting piece 22 is in threaded cooperation with the outside of the threaded rod 21. As Figure 4 shown, after the rotation of the threaded rod 21 and the limitation of the guiding frame 8, the limiting piece 22 is transformed from a rotational motion into a horizontal linear motion. A first reserved hole 23 is penetrated through the inside of the first guiding column 7, and the diameter of the first reserved hole 23 is larger than the diameter of the threaded rod 21. When the first guiding column 7 extends into the inside of the guiding frame 8, the threaded rod 21 will be embedded into the first reserved hole 23. During the embedding process, the horizontal position of the limiting piece 22 can limit the extending distance of the first guiding column 7. By limiting the first guiding column 7, the extending distance of the grinding wheel 10 can be limited;

[0031] In this embodiment, as Figure 3 and Figure 4 shown, a second sector gear 20 is arranged towards the inside of the guiding frame 8 on the threaded rod 21. The second sector gear 20 is fixedly welded to the threaded rod 21. The second sector gear 20 is rotatably connected to the inner wall of the guiding frame 8. A first sector gear 19 is arranged on one side outside the second sector gear 20, and the outside of the first sector gear 19 is meshed with the outside of the second sector gear 20. By rotating the first sector gear 19, the second sector gear 20 and the threaded rod 21 connected at one end can be driven to rotate, and then the horizontal position of the limiting piece 22 can be adjusted;

[0032] In this embodiment, a second handle 18 penetrates through the guiding frame 8 on the first sector gear 19. By rotating the second handle 18, the first sector gear 19 can be driven to rotate. As Figure 3 and Figure 4 shown, a scale 25 is arranged at the upper end inside the guiding frame 8. The scale 25 is made of a transparent material, and the user can directly observe the horizontal position of the limiting piece 22 through the transparent material.

[0033] Working principle: When using the device to groove the wall surface, the rollers at the four corners of the lower end of the base 1 can drive the whole device to move horizontally. The hydraulic telescopic rod 2 can be extended or retracted to adjust the horizontal height of the grinding wheel 10. Rotating the second handle 18 drives the first sector gear 19 to rotate. The rotation of the first sector gear 19 drives the second sector gear 20 to rotate. The rotation of the second sector gear 20 drives the threaded rod 21 to rotate. Relative movement occurs between the outside of the threaded rod 21 and the inside of the limiting piece 22. After being restricted by the inside of the guiding frame 8, the rotational movement of the limiting piece 22 is transformed into a horizontal linear movement. The position of the limiting piece 22 is adjusted by the horizontal linear movement. Press the first handle 6, and the first handle 6 will drive the pressing piece 5 and the first guiding column 7 to move horizontally at the same time. The second guiding column 12 will be inserted into the second reserved hole 24 around the pressing piece 5, and the first guiding column 7 will be inserted into the inside of the guiding frame 8. The rotating grinding wheel 10 will contact the wall after being pushed, contact the wall and groove it. The limiting piece 22 can limit the extending distance of the first guiding column 7. The grooving generated by the rotation of the grinding wheel 10 will cause the splashing of particles. The particles will move towards the inside of the wrapping frame 4 along with the grinding wheel 10. The particles will flow towards the receiving frame 9 under the diversion of the inclined surface 16 of the inner wall of the dust receiving block 13. Some of the particles flowing along with the grinding wheel 10 will stay inside the limiting arc 17 due to the collision of the dust limiting block 14. After the grinding wheel 10 stops rotating, it will fall into the dust collection bucket 15 again. The dust collection bucket 15 can be slid out to handle the particles wrapped and collected by the wrapping frame 4.
