[0027] As Figures 1-3 shown, a fresh raw milk detection sampling device includes a sampling mechanism 1, the sampling mechanism 1 is located on a tank body 2, the sampling mechanism 1 includes an outer shell 11, a sampling cylinder 12, an extraction cylinder 13, a lifting rod 14, a support frame 15, a driving rod 16, and a support rod 17. The sampling cylinder 12 is located inside the outer shell 11. The extraction cylinder 13 passes through the outer shell 11 and is connected to the sampling cylinder 12. A piston 131 is arranged inside the extraction cylinder 13. The support frame 15 is located on the extraction cylinder 13. One end of the lifting rod 14 is movably connected to the support frame 15, and the other end passes through the extraction cylinder 13 and is connected to the piston 131. One end of the driving rod 16 is connected to the lifting rod 14.

[0028] The bottom of the sampling cylinder 12 is provided with a sampling inlet 121, and the top is provided with a first channel 122. The sampling inlet 121 is connected to a sampling tube 110, and the sampling tube 110 extends into the tank body 2. A first partition 123 is arranged on the sampling cylinder 12. One end of the first partition 123 is rotatably connected to the sampling cylinder 12, and the first partition 123 is located above the first channel 122. The outer diameter of the first partition 123 is larger than the inner diameter of the first channel 122; the inner diameter of the extraction cylinder 13 is larger than the outer diameter of the first partition 123. The first partition 123 can completely cover the first channel 122 when at rest.

[0029] A second channel 132 is arranged in the middle of the piston 131. A second partition 133 is arranged on the piston 131. One end of the second partition 133 is rotatably connected to the piston 131. The outer diameter of the second partition 133 is larger than the inner diameter of the second channel 132. The second partition 133 can completely cover the second channel 132 when at rest.

[0030] The upper part of the extraction cylinder body 13 is provided with a sample outlet 134, and the sample outlet 134 is located above the piston 131. The sample outlet 134 can be connected to a sampling bottle through a pipeline.

[0031] A support block 18 is arranged on one side of the extraction cylinder body 13. One end of a support rod 17 is connected to the support block 18, and the other end is rotatably connected to the driving rod 16. The support rod 17 provides support for the driving rod 16. The driving rod 16 is manually pressed down for sampling, and the number of times of pressing down the driving rod 16 can be adjusted according to the requirement of the sampling volume.

[0032] A bracket 19 is arranged at the bottom of the outer shell body 11, and the outer shell body 11 is detachably connected to the tank body 2 through the bracket 19. The bottom of the bracket 19 can adopt a vacuum suction cup or a small electric suction cup to adsorb on the tank body 2.

[0033] Implementation process:

[0034] Fix the bracket 19 of the sampling mechanism 1 on the tank body 2, then connect the sampling tube 110 to the sample inlet 121, open the tank opening 21 of the tank body 2, put the lower end of the sampling tube 110 into the tank body 2, and then press down the lower part of the driving rod 16. At this time, the upper end of the driving rod 16 rises, driving the lifting rod 14 to rise, and further driving the piston 131 to rise. At this time, the pressure in the extraction cylinder body 13 increases, and the pressure in the sampling cylinder body 12 decreases. One end of the first partition plate 123 rises, and the second partition plate 133 covers the second channel 132. Thus, the milk in the tank body 2 is sucked into the sampling cylinder body 12 through the sampling tube 110, and then the milk enters the extraction cylinder body 13 through the first channel 122. Then, lift the driving rod 16 to drive the piston 131 to move downward. At this time, the pressure in the extraction cylinder body 13 increases and the pressure in the sampling cylinder body 12 decreases, causing the second partition plate 133 to open and the first partition plate 123 to cover the first channel 122. The milk enters the sampling cylinder body 12. After the liquid level is higher than the sample outlet 134, it flows out through the sample outlet 134 to complete the sampling. After use, deionized water or distilled water can be used for sampling and flushing. After flushing, the next sampling can be carried out.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
