[0029] In order to facilitate component installation, as shown in the attached Figure 4 As shown, a communication column head 14 is arranged at both ends of the sampling bottle 5, an installation screw hole is arranged in the inside of the communication column head 14, the sealing plug column 6, the installation sealing block 7 and the spring 8 are all installed in the inside of the installation screw hole, a screw thread is arranged at the front of the installation screw hole, the installation sealing block 7 is screwed to the inside of the installation screw hole, and the installation sealing block 7 is located at the opening side of the installation screw hole.

When the bottle 5 is in the open position, the sealing plug 6 at the front end of the bottle 5 moves backward to separate from the material taking hole 15 on the side of the mounting block 7, thereby realizing the communication between the bottle 5 and the hopper, and the medicine enters the bottle 5 through the material taking hole 15. When the sampling plug 3 contacts the end of the regulating limit rod 4, the material taking stops, and the sealing plugs 6 on both sides of the sampling bottle 5 are re-fitted and sealed by the thrust of the spring 8 after losing the suction effect, thereby realizing the sealing of the material taking hole 15 at the end of the sampling bottle 5. Thereafter, the sampling bottle 5 is disassembled and replaced to complete the sampling operation. When discharging the medicine liquid, it is only necessary to switch the mounting end of the sampling bottle 5.
