[0033] Specifically, by injecting the sample through the injection valve 16, then starting the servo motor 5, the rotating column 6 rotates accordingly, driving the stirring blade 7 to rotate, thereby ensuring that the sample can be fully mixed. After the mixing process is completed, the sample enters the detection device 10 through the connection valve 9. Driven by the electric push rod 12, the pushing piston 13 moves downward, so that the chemical liquid inside the liquid injection pipe 15 is injected into the detection device 10 through its bottom end, enabling the chemical reactions and changes inside the detection device 10 to smoothly carry out the automatic detection work. At the same time, the cleaning disc 14 moves together with the movement of the pushing piston 13, ensuring that the chemical agent residues on the inner wall of the liquid injection pipe 15 are cleaned, improving the cleanliness of the inner wall of the liquid injection pipe 15, thereby reducing the labor intensity of the operator and improving the overall work efficiency.

[0034] Reference Figure 1 、 Figure 3 and Figure 5 The mixing mechanism 2 includes a power blower 201, the bottom wall of the power blower 201 is fixedly connected to the rear side of the top wall of the workbench 1, one end of the power blower 201 is communicated with a suction pipe 202, the front end of the suction pipe 202 is communicated with a filter box 203, a plurality of filter columns 204 are fixedly connected to the top of the filter box 203 at equal intervals, the other end of the power blower 201 is communicated with a delivery pipe 205, and one end of the delivery pipe 205 is communicated with an annular spray head 206, and the outer wall of the annular spray head 206 is fixedly connected to the right inner wall of the processing barrel 4;

[0035] Specifically, by starting the power blower 201, the extraction pipe 202 is connected to the filtration box 203, thereby achieving the extraction of external air. The extracted air is filtered through multiple filter columns 204 to complete the removal of large particulate impurities in the air, ensuring that these particulate impurities will not have a negative impact on the homogenization work. The filtered air is then transported through the delivery pipe 205 to reach the annular nozzle 206. The annular nozzle 206 sprays the filtered air using high pressure to efficiently mix the samples. This jet of air enables the samples inside the treatment barrel 4 to fully flow and mix, thus significantly improving the efficiency of sample homogenization and mixing, optimizing the quality of sample processing, and shortening the time required for detection.

[0036] Refer to Figure 1 、 Figure 2 and Figure 5 The mixing mechanism 2 further includes a rubber ring 207, and the inner wall of the rubber ring 207 is fixedly installed on the outer wall of the extraction pipe 202; a control switch 17 is fixedly connected to the front side of the workbench 1, and the control switch 17 is electrically connected to the servo motor 5, the electric push rod 12, and the power blower 201 respectively; a plurality of square grooves 8 are equidistantly arranged on the outer wall of the stirring blade 7, and the plurality of square grooves 8 are all symmetrically designed.

[0037] Specifically, the rubber ring 207 enables the protection of the front connection part of the extraction pipe 202, thereby increasing the service life of the extraction pipe 202. The control switch 17, which is electrically connected to the servo motor 5, the electric push rod 12, and the power blower 201 respectively, enables the control switch 17 to turn on and off the device.

[0038] Refer to Figure 1 and Figure 2 The middle part of the support frame 3 is fixedly connected with two reinforcing plates 21, and the top walls of the two reinforcing plates 21 are both provided with arc surfaces; an observation window 20 is fixedly installed on the front side of the treatment barrel 4, and the front side of the observation window 20 is smooth; two connecting plates 18 are fixedly connected to the left and right sides of the inner wall of the workbench 1 respectively, and installation grooves 19 are arranged on the top walls of the plurality of connecting plates 18.

[0039] Specifically, the reinforcing plates 21 improve the supporting effect of the support frame 3 on the treatment barrel 4, the observation window 20 facilitates the observation of the sample mixing situation, and the connecting plates 18 and the installation grooves 19 facilitate the fixed installation of the device.

[0040] Working principle: When starting to use, a sample is added through the injection valve 16 to start the homogenization work. The servo motor 5 is started, causing the rotating column 6 to drive the stirring blade 7 to rotate, so that the sample can be mixed. After the mixing is completed, the sample enters the detection device 10 through the connection valve 9. Under the start of the electric push rod 12, the downward displacement of the push piston 13 is caused, so that the chemical liquid inside the liquid injection pipe 15 is injected into the detection device 10 through the bottom end of the liquid injection pipe 15. Then, through the reaction and change inside the detection device 10, the automatic detection work is completed. At the same time, the cleaning disc 14 moves together with the push piston, so that the chemical agent attached to the inner wall of the liquid injection pipe 15 can be cleaned, thereby improving the cleaning of the inner wall of the liquid injection pipe 15, reducing the labor cost of the operator, improving the work efficiency, and completing the situation of the automatic liquid injection experiment. And through the start of the power blower 201, it extracts the outside air through the extraction pipe 202 by means of the filter box 203. Then, the outside air performs the work of filtering large particle impurities through a plurality of filter columns 204, avoiding the influence of particle impurities on the homogenization work. Thus, the filtered air is transported through the delivery pipe 205 and is sprayed onto the sample at high pressure through the annular nozzle 206, so that the output air flow can mix and flow the sample inside the treatment barrel 4, thereby improving the sample homogenization efficiency and shortening the detection time. Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
