[0020] See also Figure 1-2A dynamic tamping machine comprises a dynamic tamping machine hammer 1, wherein the dynamic tamping machine hammer 1 is provided with a vent hole 2, wherein the number of the vent holes 2 is five, and the five vent holes 2 are distributed in a circular array with the center of the circle of the dynamic tamping machine hammer 1 as the center, wherein a holder 3 is fixedly installed on the top of the dynamic tamping machine hammer 1, wherein a connecting bracket 4 is plugged into the inside of the holder 3, wherein a connecting plate 5 is fixedly installed on the top of the connecting bracket 4, wherein a threaded sleeve 6 is fixedly installed on the top of the connecting plate 5, wherein a cleaning rod 7 is connected to the inner thread of the threaded sleeve 6, wherein the ... A threaded head 8 is fixedly installed on the top of the rod 7, and the top of the connecting plate 5 is rotatably connected to the main shaft 9. The bottom end of the main shaft 9 is rotatably connected to the output shaft of the driving motor 10. The bottom end of the driving motor 10 is movably connected to the top of the rammer 1 of the rammer machine. The top output shaft of the driving motor 10 passes through the bottom axis of the connecting plate 5 and is fixedly connected to the main shaft 9 above the connecting plate 5. The outside of the main shaft 9 is movably connected to the outer wall of the threaded head 8 through a thread, and the outer wall of the cleaning rod 7 is connected to the internal thread of the threaded sleeve 6 through a thread.

[0021] according to Figure 2 A screw rod 11 is fixedly installed at the bottom end of the cleaning rod 7, and a mud cleaning drill bit 12 is connected to the external thread of the screw rod 11. Mud scrapers 13 are fixedly installed on both sides of the mud cleaning drill bit 12. A mud scraper 14 is fixedly installed on the outer side of the bottom of the mud cleaning drill bit 12, and a drill bit 15 is fixedly installed at the bottom end of the mud cleaning drill bit 12. The threaded connection direction of the screw rod 11 and the mud cleaning drill bit 12 is opposite to the threaded connection direction of the threaded sleeve 6 and the cleaning rod 7.

[0022] During use, after the rammer 1 of the ramming machine is used, the main shaft 9 is installed and placed above the rammer 1 by connecting the connecting bracket 4 and the socket 3. Then, the driving motor 10 is placed above the rammer 1 and connected to the axis of the main shaft 9 through the output shaft, so that the main shaft 9 rotates. As the main shaft 9 rotates, the threaded heads 8 on both sides are driven to rotate and move downward, so that the cleaning rod 7 can drive the mud cleaning drill bit 12 to clean the inner wall of the vent 2, thereby avoiding blockage of the vent 2 and facilitating the next use of the rammer 1 of the ramming machine. The specific process for cleaning the clay is as follows: by starting the driving motor 10, the output shaft of the driving motor 10 drives the main shaft 9 to rotate. As the main shaft 9 rotates, the outer side of the main shaft 9 is threadedly connected to the outer walls of the two threaded heads 8 through threads. Therefore, the rotation of the main shaft 9 can drive the threaded heads 8 to rotate. Moreover, because the outer side of the cleaning rod 7 is threadedly connected to the threaded sleeve 6 through threads, and the outer side of the threaded sleeve 6 is fixedly connected to the inner side of the connecting plate 5, when the threaded sleeve 6 cannot rotate and move, the threaded head 8 drives the cleaning rod 7 to rotate and move downward. Thereby, the mud cleaning drill bit 12 can be moved from top to bottom inside the air hole 2, and because the scraper plate 13 and the scraper knife 14 are provided, the mud cleaning drill bit 12 can clean the clay on the inner wall of the air hole 2 during the rotation, wherein the outer part of the cleaning rod 7 is threadedly connected to the mud cleaning drill bit 12 through the screw 11, and the threaded connection direction is opposite to the threaded sleeve 6 and the cleaning rod 7. Therefore, as the mud cleaning drill bit 12 rotates, the mud cleaning drill bit 12 and the cleaning rod 7 can be turned tighter and tighter, which can prevent the mud cleaning drill bit 12 from falling off during the mud cleaning process.
