[0042] The working principle of the present invention is as follows: an inner support spring 304 and an outer flexible cover 301 are arranged on the outside of the drill rod body 302, a rear outer support ring 306, a middle outer support ring 307 and a front outer support ring 308 are sleeved on the outside of the drill rod body 302, a rear inner connecting tube 309, a middle inner connecting tube 310 and a front inner connecting tube 311 are fixed in the middle of the two, during the rotation drilling process of the drill rod body 302, a front positioning ring 305 is fixed to the front end of the inner support spring 304, a middle outer support ring 307 is arranged inside the front positioning ring 305, during the drilling process of the drill rod body 302, the front positioning ring 305 is supported on the outer facade, and as the drill rod body 302 advances in drilling, the inner support spring 304 can be folded and shortened, so that The dust discharged during the drilling process of the drill rod body 302 can be isolated. The rear inner connecting tube 309, the middle inner connecting tube 310 and the front inner connecting tube 311 are movably connected to the outside of the drill rod body 302. The inner threaded tube 326 is fixed inside the rear inner connecting tube 309, the middle inner connecting tube 310 and the front inner connecting tube 311. The inner threaded tube 326 and the drill rod body 302 are engaged with a large gap. In this way, the inner threaded tube 326 can rotate under the drive of the rotation of the drill rod body 302. The rotation speed of the inner threaded tube 326 changes with the rotation speed of the drill rod body 302. The faster the rotation speed, the more dust is brought out during the drilling process. The faster the drilling, the faster the front end of the drill rod body 302 enters the hole. In this way, not only the drill rod body 302 02 rotates the rear inner connecting tube 309, the middle inner connecting tube 310 and the front inner connecting tube 311. At the same time, the rear inner connecting tube 309 at the front end is squeezed and moves inward, which speeds up the rotation of the rear inner connecting tube 309. A rear push spring 315 and a front push spring 318 are arranged in the middle of the rear inner connecting tube 309, the middle inner connecting tube 310 and the front inner connecting tube 311. After the rear inner connecting tube 309 moves, the distance between them becomes smaller. The rear push spring 315 and the front push spring 318 will push the middle inner connecting tube 310 and the front inner connecting tube 311 to rotate. In this way, the faster the rotation speed of the drill rod body 302 is, the faster the front end of the drill rod body 302 enters. The pipe 310 and the front inner connecting pipe 311 are subjected to the extrusion force from the rear inner connecting pipe 309 to the front inner connecting pipe 311, which pushes them outward along the drill rod body 302, so that the rotation speed will increase, which is conducive to increasing the outward wind force to discharge the dust, realize the positive cycle of dust removal, and prevent the dust from accumulating, so as to avoid affecting the progress of drilling of the drill rod body 302. A connecting vertical plate 208 is fixed to the front end of the outer flexible cover 301, an electrostatic dust removal box 201 is fixed to the outside of the connecting vertical plate 208, a top battery panel 205 is fixed to the top surface of the electrostatic dust removal box 201, a left dust removal plate 203 and a right dust removal plate 202 are fixed to both sides of the inside of the electrostatic dust removal box 201, and a bottom collecting plate 204 is fixed to the inside of the electrostatic dust removal box 201.The left circuit 206 and the right circuit 207 are connected to the two ends of the top battery panel 205, and then the left dust removal plate 203 and the right dust removal plate 202 are connected respectively, and then the left circuit 206 and the right circuit 207 are connected to the drilling device speed switch of the drilling mechanism 1. The drilling device speed switch can control the speed of the drill rod body 302. By connecting the left circuit 206 and the right circuit 207, the voltage between the left dust removal plate 203 and the right dust removal plate 202 can be adjusted with the speed of the drill rod body 302, which is beneficial to the dust removal during the drilling process. The greater the speed of the drill rod body 302, the more dust is absorbed by the surface of the left dust removal plate 203 and the right dust removal plate 202, which is beneficial to the dust removal of drilling. After the drill rod body 302 stops rotating, the dust falls into the inside of the bottom collection plate 204.
