[0003] In related technologies, existing yeast fermentation product sample extraction devices extract yeast fermentation product sample solutions through a sampling structure. However, the extracted yeast fermentation product sample solutions contain a lot of floating matter and cannot be used directly for subsequent testing. They often need to be allowed to settle, which affects the testing efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a stirring sampling device that can remove floating matter in the sample solution without requiring subsequent static sedimentation treatment of the sample solution, thereby improving detection efficiency.

[0007] The frame, with containers placed on top of it;
[0008] Sampling tube, the sampling tube is installed on the frame;
[0009] Water pump, the water pump is fixed to the frame;
[0010] The inlet pipe and outlet pipe are connected. The inlet end of the inlet pipe is connected to the sampling pipe, and the outlet end of the inlet pipe is connected to the input end of the water pump. The inlet end of the outlet pipe is connected to the output end of the water pump, and the outlet end of the outlet pipe is located above the container.
[0011] The first rotating shaft is rotatably mounted on the frame and passes through the sampling tube. Multiple first stirring components are fixedly mounted on the first rotating shaft and are located inside the sampling tube.
[0012] The driving component is used to drive the first rotating shaft to rotate.
[0013] Optionally, the stirring sampling device further includes a second stirring element, which is fixedly connected to one end of the first rotating shaft extending out of the sampling tube.
[0014] Optionally, the outer diameter of the second stirring element is larger than the outer diameter of the sampling tube.
[0015] Optionally, the drive unit includes:
[0016] A bevel gear is rotatably mounted on the frame. One end of the first rotating shaft is fixedly connected to a first bevel gear, which meshes with the bevel gear.
[0017] Optionally, the water pump is a hand-cranked pump, and the input shaft of the water pump is coaxially and fixedly connected to the bevel gear disc.
[0018] Optionally, the stirring sampling device further includes:
[0019] The first operating part is eccentrically disposed and rotatably connected to the bevel gear disk;
[0020] And / or, a second operating unit, which is fixedly installed on the water pump.
[0021] Optionally, the stirring sampling device also includes a second rotating shaft, which is rotatably mounted on the frame.

[0025] The beneficial effects of this utility model are:
[0026] The stirring sampling device provided by this utility model involves inserting a sampling tube into the sample liquid to be extracted, with the inlet tube above the liquid surface. At this time, a driving component drives the first rotating shaft to rotate, which in turn drives the first stirring component to rotate. Under the stirring action of the first stirring component, the liquid in the sampling tube undergoes a swirling motion. Under the swirling action, the floating matter in the liquid will sink downwards, that is, the floating matter in the upper part of the swirling liquid is greatly reduced. Then, the sampling tube is lowered until the inlet end of the inlet tube is immersed in the upper part of the swirling liquid. Then, by starting the water pump, the liquid enters the water pump under the drive of the water pump, and after the liquid is pressurized, it is injected into the container through the outlet tube. The sample liquid in the container undergoes secondary sedimentation. Finally, the container is removed and the clear sample liquid in the upper part is poured in for testing.
[0027] The first stirring element agitates the sample solution to be extracted, causing floating matter in the sample solution to sink and ensuring the clarity of the upper sample solution. This eliminates the need for subsequent static sedimentation treatment of the sample solution, greatly improving the detection efficiency of the sample solution. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0036] like Figure 1-3 As shown, an embodiment of this utility model provides a stirring sampling device, including a frame 1, a sampling tube 2, a water pump 4, an inlet pipe 8, an outlet pipe 9, a first rotating shaft 3, and a driving component. A container 6 is placed on top of the frame 1. The sampling tube 2 is installed on the frame 1, and the water pump 4 is fixed to the frame 1. The inlet end of the inlet pipe 8 is connected to the sampling tube 2, and the outlet end of the inlet pipe 8 is connected to the input end of the water pump 4. The inlet end of the outlet pipe 9 is connected to the output end of the water pump 4, and the outlet end of the outlet pipe 9 is located above the container 6. The first rotating shaft 3 is rotatably installed on the frame 1 and passes through the sampling tube 2. A plurality of first stirring elements 10 are fixedly installed on the first rotating shaft 3, and the plurality of first stirring elements 10 are located inside the sampling tube 2. The driving component is used to drive the first rotating shaft 3 to rotate. Specifically, the first stirring element 10 is a stirring paddle.
[0037] By inserting the sampling tube 2 into the sample liquid to be extracted, so that the inlet tube 8 is higher than the liquid surface, the first rotating shaft 3 is driven to rotate by the driving component. The first rotating shaft 3 drives the first stirring component 10 to rotate. Under the stirring action of the first stirring component 10, the liquid in the sampling tube 2 is in a swirling motion. Under the action of swirling, the floating objects in the liquid will sink downward, that is, the floating objects in the upper part of the swirling liquid are greatly reduced. At this time, the sampling tube 2 is moved down until the inlet end of the inlet tube 8 is immersed in the upper part of the swirling liquid. Then, by starting the water pump 4, the liquid enters the water pump 4 under the drive of the water pump 4, and after the liquid is pressurized, it is injected into the container 6 through the outlet tube 9. The sample liquid in the container 6 undergoes secondary sedimentation. Finally, the container 6 is removed and the upper clear sample liquid is poured in for testing.
[0038] The first stirring element 10 agitates the sample solution to be extracted, causing floating matter in the sample solution to sink and ensuring the clarity of the upper sample solution. This eliminates the need for subsequent static sedimentation treatment of the sample solution, greatly improving the detection efficiency of the sample solution.
[0039] Optionally, container 6 is a measuring cup, which facilitates observation of the volume of the extracted sample liquid and the sedimentation of floating matter.
[0040] For example, the drive component includes a bevel gear disk 5, which is rotatably mounted on the frame 1. One end of the first rotating shaft 3 is fixedly connected to a first bevel gear 7, which meshes with the bevel gear disk 5.
[0041] The operator rotates the bevel gear disk 5, which in turn drives the first bevel gear 7 to rotate. The first bevel gear 7 then drives the first rotating shaft 3 to rotate, which in turn drives the first stirring element 10 to rotate, thereby settling and removing floating matter in the sample solution. The structure of the first bevel gear 7 and the bevel gear disk 5 is simple to operate and easy to install.
[0042] In other embodiments, the driving component can also be a drive motor, which is fixed to the frame 1 and its output end is fixedly connected to the first rotating shaft 3. The drive motor can drive the first rotating shaft 3 to rotate. By starting the drive motor to drive the first rotating shaft 3 to rotate, manpower is saved.
[0043] Furthermore, such as Figure 2 As shown, the stirring sampling device also includes a first operating part 16, which is eccentrically disposed and rotatably connected to the conical toothed disk 5. Specifically, the first operating part 16 is a hand crank.
[0044] The operator can rotate the bevel gear disk 5 by rotating the first operating part 16, which makes it easier for the operator to drive the bevel gear disk 5 to rotate and improves the ease of operation.
[0045] Furthermore, the water pump 4 is a hand-cranked pump, and the input shaft of the water pump 4 is coaxially and fixedly connected to the bevel gear disc 5.
[0046] The operator rotates the first operating part 16 to drive the conical disc 5 to rotate, which in turn drives the input shaft of the water pump 4 to rotate, thus enabling the water pump 4 to operate and extract the sample liquid from the sampling tube 2 and inject it into the container 6. By manually rotating the first operating part 16, the first stirring element 10 is agitated to ensure the clarity of the sample liquid, while the water pump 4 can promptly extract the clear sample liquid, preventing the settled floating matter from rising again and affecting the clarity of the sample liquid.
[0047] In other embodiments, the water pump 4 may also be an electric water pump.
[0048] Furthermore, the stirring sampling device also includes a second operating part 17, which is fixedly installed on the water pump 4. Specifically, the second operating part 17 is a handle.
[0049] The operator can hold the device firmly through the second operating section 17, which can ensure the stability of the device.
[0050] Furthermore, the stirring sampling device also includes a second stirring element 15, which is fixedly connected to one end of the first rotating shaft 3 extending out of the sampling tube 2. Specifically, the second stirring element 15 is a stirring paddle.
[0051] Before the sampling tube 2 is immersed in the sample solution to be extracted, the second stirring element 15 first contacts the liquid surface. At this time, the driving element is activated, driving the first rotating shaft 3 to rotate. The first rotating shaft 3 drives the second stirring element 15 to rotate, so that the second stirring element 15 removes the floating objects on the liquid surface. After removing the floating objects on the liquid surface, the sampling tube 2 is then inserted into the sample solution to be extracted, which reduces the amount of floating objects entering the sampling tube 2 and ensures the clarity of the sample solution to a certain extent. Then, the first stirring element 10 is used to stir the sample solution. Under the dual stirring action of the second stirring element 15 and the first stirring element 10, the clarity of the sample solution can be greatly improved, thereby improving the detection effect of the sample solution.
[0052] Furthermore, the outer diameter of the second stirring element 15 is larger than the outer diameter of the sampling tube 2. With this configuration, the stirring radius of the second stirring element 15 is larger, which keeps the floating objects away from the inlet of the sampling tube 2, effectively reducing the amount of floating objects entering the sampling tube 2.
[0053] Furthermore, the stirring sampling device also includes a second rotating shaft 11, which is rotatably mounted on the frame 1. One end of the second rotating shaft 11 is fixedly connected to a second bevel gear 12, and the other end is fixedly connected to a tray 13. The tray 13 is used to place the container 6, and the second bevel gear 12 meshes with the bevel gear disk 5.
[0054] After the sample solution is injected into container 6, rotating the first operating part 16 drives the bevel gear 5 to rotate, which in turn drives the second bevel gear 12 to rotate. The second bevel gear 12 then drives the second rotating shaft 11 to rotate, which in turn drives the tray 13 to rotate. Container 6 rotates together with tray 13. Under the action of centrifugal force, the sample solution in container 6 will further settle. Container 6 can then be removed, and the supernatant can be collected for use, further reducing the content of floating matter in the sample solution and greatly improving the detection effect.
[0055] Furthermore, the tray 13 is provided with a limiting part along its circumference, and an elastic element 14 is sandwiched between the limiting part and the container 6. Specifically, the elastic element 14 is a rubber ring.
[0056] The container 6 is in elastic contact with the limiting part through the elastic element 14. The centrifugal force generated during rotation may cause the container 6 to vibrate slightly. The elastic element 14 absorbs the vibration energy through the damping effect, maintaining the stability of the sample liquid in the container 6 during the precipitation process.
[0057] Furthermore, the distance between the outlet end of the liquid outlet pipe 9 and the upper edge of the container 6 is not less than 5cm. This design avoids interference between the liquid outlet pipe 9 and the container 6 during the process of picking up and putting down the container 6, making it convenient to pick up and put down the container 6.
[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
