An anti-slip pad 15 is fixedly connected to the top of the handle 14. A sealing ring 13 is fixedly connected to the bottom end of the handle 14, and the sealing ring 13 is located outside the connecting shaft 19.

[0023] The first electric push rod 11, the second electric push rod 12, the motor 16 and the quantitative sensor 9 are all electrically connected to the PLC controller 17. The stirring blade 6 is provided with two sets, and the support rod 10 is movably hinged to the stirring blade 6.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, during sampling, the sampler 1 is inserted into the chemical auxiliary agent storage tank through the sampling port. The sealing ring 13 at the bottom of the handle 14 can improve the sealing of the insertion sampling. Then, the second electric push rod 12 pushes the adjustment plate 3 downward. When the adjustment plate 3 moves down, the support rod 10 can open the two sets of stirring blades 6. Then, before sampling, the motor 16 drives the sampler 1 to rotate at a uniform speed to fully stir the chemical reagent. After stirring, the sampling tube 7 can sample the uniformly mixed chemical reagent.

The sealing ring 13 at the bottom of the handle 14 improves the sealing of the insertion sampling. Then, the second electric push rod 12 pushes the adjusting plate 3 downward. When the adjusting plate 3 moves down, the support rod 10 can open the two sets of stirring blades 6. Then, before sampling, the motor 16 drives the sampler 1 to rotate at a uniform speed to fully stir the chemical reagent. After stirring, the sampling tube 7 can sample the uniformly mixed chemical reagent. The first electric push rod 11 can pull the piston plate 8 upward. The air pressure difference formed during the upward movement of the piston plate 8 can draw the chemical auxiliary agent liquid into the sampling tube 7 to achieve sampling. The quantitative sensor 9 inside the sampling tube 7 is distributed at 5ml intervals. The quantitative sensor 9 can detect the extracted chemical additives in real time, and the detected data is fed back to the PLC controller 17. The PLC controller 17 can control the start and stop of the first electric push rod 11 to achieve accurate sampling. The sampling tube 7 is connected to the adjustment plate 3 through the threaded block 21. The threaded block 21 at the top of the sampling tube 7 is embedded in the threaded groove 20 of the adjustment plate 3 and then screwed in. The threaded block 21 is inserted into the threaded groove 20 and fixedly connected by threads. When disassembling, it is only necessary to rotate the sampling tube 7 in the opposite direction and remove the threaded block 21 at the top of the sampling tube 7 from the threaded groove 20 to complete the disassembly. After disassembly, it is convenient to clean the inside of the sampler 1 and the sampling tube 7. This structure realizes the function of easy disassembly and cleaning.
