[0002] In order to evaluate the quality and performance of polysilicon, staff need to sample and process the polysilicon cores. By testing and analyzing the polysilicon cores, they can understand its chemical composition, crystal structure, mechanical properties, electrical properties and other aspects, and thus determine whether the polysilicon meets the requirements of the production process and the needs of downstream applications.

[0003] Currently, when staff use drilling tools to sample polysilicon sample cores, the samples obtained will enter the interior of the drilling tools. After the sampling is completed, the staff need to remove the samples from the interior of the drilling tools. However, the current removal method is mostly manual removal by staff with the help of tools (such as through a shovel or a spoon). It is inconvenient to remove the samples after entering the drill tool, which causes the staff to spend a lot of time when removing the samples from the drill tool, reducing the sampling efficiency of the polysilicon sample cores.

[0024] The positioning structure 8 includes a threaded rod 81, a knob 82, a threaded sleeve 83 and a connecting rod 84. The threaded rod 81 is rotatably connected to the inside of the fixing frame 7, the knob 82 is rotatably connected to the left side of the fixing frame 7, and the right end of the knob 82 passes through the fixing frame 7 and is fixedly connected to the left end of the threaded rod 81. The threaded sleeve 83 is arranged on the surface of the threaded rod 81, and the connecting rod 84 is fixed on the front and rear sides of the threaded sleeve 83. One end of the connecting rod 84 passes through the through groove 9 and is fixedly connected to the clamping plate 10. The thread directions on the left and right sides of the surface of the threaded rod 81 are arranged in opposite directions. There are two threaded sleeves 83, and they are symmetrically arranged on the left and right sides of the surface of the threaded rod 81. The threaded sleeve 83 is threadedly connected to the threaded rod 81. After the staff rotates the knob 82 on one side, the threaded rod 81 can be rotated, and the threaded sleeves 83 on both sides of the surface of the threaded rod 81 can move toward each other, thereby controlling the clamping plates 10 on both sides above to move toward the polysilicon sample core, thereby clamping and fixing the polysilicon sample core.

The fixed block 133 is fixed to one side of the surface of the rotating disk 132. The movable frame 134 is set on the surface of the rotating disk 132, and the fixed block 133 is located inside the movable frame 134 and is slidably connected to the inner wall of the movable frame 134. The push rod 135 is fixed to the rear side of the movable frame 134 and pushes The rear end of the rod 135 is bolted to the surface of the slapping plate 14, and a guide sleeve 17 is fixed to the rear of the top of the mounting platform 12, and the push rod 135 passes through the guide sleeve 17 and is slidably connected to the inner wall of the guide sleeve 17. After the staff turns on the motor 131, the output shaft of the motor 131 can drive the upper rotating disk 132 to rotate, so that the fixed block 133 moves. When the fixed block 133 moves inside the movable frame 134, the guide sleeve 17 at the rear can guide the push rod 135, so that the push rod 135 pushes the slapping plate 14 to move back and forth in the front and rear directions, so that the slapping plate 14 slaps the surface of the drilling tool body 6 back and forth.

[0027] Working principle: When the staff needs to sample the polysilicon sample core, the staff first places the polysilicon sample core on the surface of the sampling table 1, and then the staff rotates the knob 82 on one side, thereby moving the clamping plates 10 on both sides, and then adjusts the position of the clamping plates 10 on both sides according to the size of the polysilicon sample core, so that the clamping plates 10 clamp and fix the polysilicon sample core. After the fixation is completed, the staff can open the upper drive device 5 to rotate the drill body 6. At this time, the staff controls the drill body 6 to move downward through the hydraulic cylinder 3, so that the drill body 6 It contacts the polysilicon sample core below and then performs a sampling operation on the polysilicon sample core. After the sampling is completed, the staff controls the output shaft of the hydraulic cylinder 3 to make the drill body 6 rise back to its original position, and then the staff turns off the drive device 5 to stop the drill body 6 from rotating. The staff turns on the front motor 131 to push out the slapping plate 14, which slaps the surface of the drill body 6, causing the entire drill body 6 to vibrate. By slapping, the polysilicon sample core sampled inside the drill body 6 falls out, thereby completing the sampling operation on the polysilicon sample core.
