[0045] The support column 20 is higher than the second support arm 23 (the support column 20 can limit the anti-falling arm 19 and prevent the anti-falling arm 19 from rotating too large), and the top of the first support arm 21 and the second support arm 23 are both provided with a stabilizing groove 24 for clamping the anti-falling arm 19.

[0046] The material quantitative extraction device provided by the utility model, when sampling the liquid in the fermentation material (also other reactants or dissolved materials), first, the first control mechanism controls the sealing plug 6 to open, and then the whole container body 1 is immersed in the fermentation material, wherein the filter hole 2 can prevent the fermentation solid from entering the container body 1, and the filter screen 7 can prevent the fermentation solid from entering the discharge pipe 5 and the sampling dish 4. After the container body 1 is immersed in the fermentation liquid for a period of time, the container body 1 and the sampling dish 4 are both filled with liquid. Then the first control mechanism controls the sealing plug 6 to close the discharge pipe 5, and the container body 1 is taken out from the fermentation material, at this time, the liquid outside the sampling dish 4 can flow out directly through the filter hole 2 at the bottom of the container body 1. When the liquid outside the sampling dish 4 is completely flowed out, the container for receiving the sampling liquid is placed at the bottom of the discharge pipe 5 or connected at the bottom of the discharge pipe 5, and then the first control mechanism controls the sealing plug 6 to be lifted, at this time, the liquid in the sampling dish 4 flows out and is received, and the sampling of the liquid is completed.

[0047] The structure of the application does not need to filter the extracted material when sampling, so that the sampling is simpler. Since the capacity of the sampling dish 4 is fixed, the amount of liquid extracted each time is fixed, and subsequent detection is not needed to take or calculate the amount of material again, so that the sampling operation effect is better.

[0048] In the actual sampling, first, the operating rod 18 is rotated, and the anti-falling arm 19 is swung to the side of the first supporting arm 21 and the second supporting arm 23; then the operating rod 18 is raised upward, and after the anti-falling arm 19 is higher than the second supporting arm 23, the operating rod 18 is rotated, so that the anti-falling arm 19 is rotated and clamped into the stabilizing groove 24 of the second supporting arm 23; at this time, not only the sealing cover 13 is separated from the sampling dish 4, but also the sealing plug 6 opens the discharge pipe 5. Therefore, the worker can immerse the container body 1 into the fermentation liquid through the handle 8, so that the fermentation liquid easily fills the container body 1 and the sampling dish 4.

[0049] Then the worker clamps the anti-falling arm 19 into the stabilizing groove 24 of the first supporting arm 21 through the operating rod 18; at this time, under the elastic force of the first elastic member 12, the sealing part 6a is tightly attached to the inner wall of the transmission part 5a, and the extension part 6b is inserted into the discharge part 5b; after the liquid in the container body 1 flows stably, the anti-falling arm 19 is separated from the first supporting arm 21; at this time, under the elastic force of the second elastic member 14, the sealing cover 13 and the leakage prevention groove seal the sampling dish 4. Alternatively, after the anti-falling arm 19 is separated from the second supporting arm 23, the lowering speed of the operating rod 18 is slowly reduced, so that the sealing cover 13 seals the sampling dish 4.

[0050] After the container body 1 is taken out to the outside, since the sealing plug 6 and the sealing cover 13 seal both ends of the sampling dish 4, spilling or overflowing does not occur during the operation, so that the volume of the liquid discharged from the sampling dish 4 can be better guaranteed, and the sampling effect is better.

[0051] Since the cross section of the linkage column 15 is rectangular, the sealing cover 13 can only be vertically raised and lowered and cannot be rotated, so that the second elastic member 14 can normally move; and the linkage column 15 cannot rotate with the rotation of the operating rod 18; similarly, the stabilizing rod 11 can make the sealing plug 6 only vertically raise and lower and cannot rotate, so that the first elastic member 12 can stably drive the sealing plug 6 to move. Furthermore, since the transmission part 5a and the sealing part 6a are both circular truncated cones (or the cross sections are inverted trumpets), the sealing performance of the two can be improved, and the sampling stability is better. During the entire operation, the raising and lowering of the sealing plug 6 is controlled through the linkage cable 22, and the linkage cable 22 is controlled through the sealing cover 13, so that only one operating rod 18 can be used to operate the sealing plug 6 and the sealing cover 13, and the operation is more simple and convenient. The linkage cable 22 can be deformed, but has no elasticity or has very small elasticity.

[0052] It should also be understood that the filter hole 2 and the filter screen 7 have small pore sizes, and can filter solid objects, and the figure is only schematic and does not represent the actual structure.

[0053] The above description is only a description of the preferred embodiments of the present application, and is not any limitation on the scope of the present application. Any modification or modification made by a person skilled in the art according to the above disclosure is within the protection scope of the claims.
