[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides a drilling and hole cleaning device, such as Figure 1 and Figure 2 As shown, it includes a main pipe 1, a scraping assembly 2, a collecting head 4 and a scraping disc 5. The outer side of the main pipe 1 is provided with a scraping assembly 2, and the scraping assembly 2 includes an outer cylinder 21, bristles 22 and an air outlet pipe 23. The outer cylinder 21 is rotatably and slidably connected to the outer side of the main pipe 1, and the bristles 22 are fixedly connected to the circumferential side of the outer cylinder 21. A plurality of bristles 22 are arranged circumferentially around the axis of the outer cylinder 21, and the bristles 22 arranged circumferentially at the same height are arranged linearly along the length direction of the outer cylinder 21, as shown in FIG. Figure 4 As shown, multiple air outlet pipes 23 are fixedly connected to the outer tube 21, and the air outlet pipes 23 are connected to the outer tube 21. The length of the air outlet pipes 23 is shorter than the length of the bristles 22 to prevent the bristles 22 from scratching the air outlet pipes 23 when cleaning the inner wall of the hole. The upper end of the outer tube 21 is fixedly connected to the end tube 212, and the upper end of the main tube 1 is fixedly connected to the plug 14. The collecting head 4 is inserted into the bottom of the drilled hole, and the peripheral side of the scraper 5 is against the inner wall of the hole. The main pipe 1 is rotated to make the scraper 5 rotate synchronously. The scraping teeth 51 provided on the scraper 5 can scrape the debris on the inner wall of the hole. The outer pipe 21 is rotated by the end tube 212 and is slid along the length direction of the main pipe 1 during the rotation, so that the bristles 22 clean the attachments and dust on the inner wall of the hole, and the scraped debris will fall into the inner cavity of the collecting head 4. After the inner wall of the hole of a certain depth is cleaned, the main pipe 1 is pulled to move the scraper 5 outward to the next height, and the scraping work is repeated again until the entire hole is cleaned. As the collecting head 4 is taken out of the hole, the debris in the collecting head 4 is dumped out.

[0028] like Figure 2And Figure 3 As shown in the figure, the collecting head 4 is fixedly connected to the lower end of the main pipe 1, and the scraping disc 5 is fixedly connected to the upper end of the collecting head 4. The collecting head 4 is a hollow hemisphere, and the main pipe 1 is arranged in the inner cavity of the collecting head 4. Figure 5 As shown in the figure, the scraping disc 5 is a circular ring, and a plurality of scraping teeth 51 are fixedly connected to the upper surface of the scraping disc 5. The plurality of scraping teeth 51 are arranged in a circle around the axis of the scraping disc 5, and the two side surfaces of the scraping tooth 51 are inclined surfaces. Figure 2 As shown in the figure, the slot 11 is arranged through the circumferential surface of the main pipe 1, and the two ends of the inner part of the outer cylinder 21 are fixedly connected with the sealing rings 211. The slot 11 is located between the two sealing rings 211, and the side of the slot 11 close to the collecting head 4 is provided with a limiting plate 12. The limiting plate 12 is rotatably connected with the main pipe 1, and the end surface of the limiting plate 12 is fixedly connected with the outer sleeve spring 3. The outer sleeve spring 3 is sleeved on the main pipe 1 and fixedly connected with the outer cylinder 21. The entire scraping assembly 2 can be rotated by rotating the end head cylinder 212. During the rotation of the end head cylinder 212, the end head cylinder 212 can be reciprocally pressed synchronously, so that the outer cylinder 21 reciprocally slides along the main pipe 1 under the action of the outer sleeve spring 3. The bristles 22 can effectively remove the attached matter and floating dust on the inner wall of the hole.

[0029] As shown in the figure, the main pipe 1 is fixedly connected with the branch pipe 13, and the branch pipe 13 is provided with the blowing assembly 6. The blowing assembly 6 can fill the inside of the main pipe 1 through the branch pipe 13. The gas enters the space between the main pipe 1 and the outer cylinder 21 separated and sealed by the two sealing rings 211 through the slot 11 on the main pipe 1, and is sprayed out through the gas outlet pipe 23 on the outer cylinder 21, which assists the bristles 22 in removing the attached matter and floating dust. Figure 6 The distance from the limiting plate 12 to the bottom of the inner cavity of the collecting head 4 is fixed, and the limiting plate 12 can rotate on the main pipe 1. During the sliding of the outer cylinder 21, the two sealing rings 211 in the outer cylinder 21 can always be located at the two ends of the slot 11 to seal the outer cylinder 21, so that the gas flow blown out of the slot 11 by the blowing assembly 6 can be discharged from the gas outlet pipe 23.

[0030] The blowing assembly 6 has two embodiments.

[0031] In the first embodiment, as shown in the figure,

[0032] Figure 7 ​As shown, the blowing assembly 6 includes a valve component 61, a hose 62 and a blowing nozzle 63. The valve component 61 is arranged at one end of the branch pipe 13, the hose 62 is arranged at the free end of the valve component 61, and the blowing nozzle 63 is fixedly connected to the hose 62. The valve component 61 includes a valve cylinder 611, a valve core spring 612 and a valve plate 613. The valve cylinder 611 is fixed on the branch pipe 13. A baffle 6111 is fixedly connected to the inner side wall of the valve cylinder 611. An air hole 6112 is provided on the side of the baffle 6111. The valve core spring 612 is arranged inside the valve cylinder 611. The valve plate 613 is fixed to one end of the valve core spring 612. The valve plate 613 is located between the valve core spring 612 and the baffle 6111. A through hole 6131 is provided on the end surface of the valve plate 613. The positions of the air hole 6112 and the through hole 6131 do not correspond. When it is impossible to use tools such as an air pump due to space limitations or other factors, you can manually blow air into the nozzle 63. The blown gas will compress the valve core spring 612, so that the valve plate 613 no longer seals the air hole 6112. The gas enters from the air hole 6112, enters the branch pipe 13 through the through hole 6131 on the valve plate 613, and is then ejected from the air outlet pipe 23. When the manual blowing stops, the valve core spring 612 resets, and the valve plate 613 blocks the air hole 6112. The airflow containing dust flows back from the air outlet pipe 23 into the branch pipe 13 and cannot pass through the valve member 61, thereby preventing people from inhaling dust.

[0033] In the second embodiment, as Figure 8 As shown, the blowing assembly 6 includes a second hose 64 and a rubber airbag 65. The second hose 64 is fixedly connected to one end of the branch pipe 13, and the rubber airbag 65 is fixed to the free end of the second hose 64. The rubber airbag 65 is hollow, and the inner cavity of the rubber airbag 65 is connected to the second hose 64. The rubber airbag 65 and the second hose 64 are connected to the external environment through the outlet pipe 23. By pressing the rubber airbag 65, the gas in the inner cavity of the rubber airbag 65 is discharged into the outlet pipe 23. When the rubber airbag 65 is not pressed, the external atmospheric pressure will re-enter the rubber airbag 65. Continuous and intermittent pressure on the rubber airbag 65 will continuously cause the air in the rubber airbag 65 to rush out of the outlet pipe 23 on the outer tube 21 and impact the inner wall of the hole.

[0034] Furthermore, the rubber airbag 65 can be replaced with an air pump to increase the air output of the air outlet pipe 23 and improve the cleaning efficiency.

[0035] Adopting this utility model, such as Figure 1 and Figure 2As shown, the collecting head 4 is inserted into the bottom of the drilled hole, the peripheral side of the scraper 5 is in contact with the inner wall of the hole, and the main pipe 1 is rotated to make the scraper 5 rotate synchronously. The scraping teeth 51 provided on the scraper 5 can scrape the debris on the inner wall of the hole, and the entire scraping assembly 2 is rotated by the end tube 212. In the process of rotating the end tube 212, the end tube 212 can be pressed back and forth synchronously, so that the outer tube 21 slides back and forth along the main pipe 1 under the action of the outer sleeve spring 3. The bristles 22 can effectively remove the attachments and floating dust on the inner wall of the hole, and the blowing assembly 6 can be blown into the inside of the main pipe 1 through the branch pipe 13. During inflation, the gas enters the space between the main pipe 1 and the outer tube 21, which is sealed by two sealing rings 211, through the notch 11 on the main pipe 1, and is then ejected through the air outlet pipe 23 on the outer tube 21, which assists the cleaning work of the bristles 22. The scraped debris will fall into the inner cavity of the collecting head 4. After the inner wall of a hole of a certain depth is cleaned, the main pipe 1 is pulled to move the scraper 5 outward to the next height, and the scraping work is repeated again until the entire hole is cleaned. As the collecting head 4 is removed from the hole, the debris in the collecting head 4 is dumped out, and the drilled hole can be deeply cleaned.

[0036] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
