[0036] like Figure 1-6 As shown, the utility model provides a technical solution:

[0037] A mixing component for homogenizing a fine-grained solid medium, and a quantitative component for quantitatively sampling the mixed fine-grained solid medium, wherein:

[0038] The mixing assembly includes a storage tank 3, which is fixedly mounted on a base 1 via a support plate 2, a mixing tank 5 is mounted on the upper portion of the storage tank 3, a lower hopper 504 is fixedly mounted on the top of the mixing tank 5, a connecting plate 4 is fixedly mounted between the lower port of the mixing tank 5 and the upper port of the storage tank 3, a feeding hole 401 is provided on the connecting plate 4, the feeding hole 401 is respectively connected to the lower port of the mixing tank 5 and the upper port of the storage tank 3, and the feeding hole 401 is opened and closed by a blocking component;

[0039] The quantitative component includes a sample delivery component, a sampling component and a control component. The sample delivery component is connected to the inlet of the storage tank 3, and the sampling component is located at the outlet of the sample delivery component. The sample delivery component and the sampling component are respectively controlled by the control component.

[0040] Through the above technical scheme, the mixing tank 5 can effectively mix the fine-particle solid medium, the storage tank 3 can temporarily store the mixed fine-particle solid medium, the sample delivery component can transport the mixed fine-particle solid medium inside the storage tank 3 to the sampling component, and the sampling component can perform quantitative sampling. Through the coordinated use of the quantitative component and the mixing component, quantitative sampling can be completed quickly, avoiding errors in manual mixing and sampling, improving the efficiency of pharmacological experiments, and reducing the cost of pharmacological experiments. Embodiment 2

[0041] like Figure 1-6 As shown, based on the first embodiment, the following improvements are made:

[0042] Furthermore, the mixing tank 5 includes a first drive motor 501 fixedly mounted on the top thereof, the output shaft of the first drive motor 501 extends into the interior of the mixing tank 5 and is fixedly connected to a stirring rod 503 through a coupling; wherein a first bearing 502 is fixedly mounted on the top of the mixing tank 5, and the output shaft of the first drive motor 501 is fixedly mounted in the inner ring of the first bearing 502.

[0043] Through the above technical solution, different types of fine-grained solid media are introduced into the interior of the mixing tank 5 from the lower hopper 504, and the stirring rod 503 is driven by the first drive motor 501 to rotate at a high speed, so that the different fine-grained solid media in the mixing tank 5 can be quickly stirred and mixed, thereby improving the mixing efficiency and quality. The lower end structure of the stirring rod 503 is parallel to the V-shaped structure at the lower end of the mixing tank 5, and can effectively stir and mix the fine-grained solid media at the bottom of the mixing tank 5. The setting of the first bearing 502 can increase the stability of the output of the first drive motor 501, which is conducive to the implementation of this utility model.

[0044] Furthermore, the blocking component includes a plug plate 403 and a hydraulic cylinder 405. A slot 402 is provided at one end of the connecting plate 4. The slot 402 is connected to the material passing hole 401. The plug plate 403 is inserted into the inside of the slot 402. The hydraulic cylinder 405 is fixedly installed on the storage tank 3 through the fixing plate 404. The telescopic end of the hydraulic cylinder 405 is fixedly connected to one end of the plug plate 403.

[0045] Through the above technical scheme, the plug plate 403 is welded and fixed to the storage tank 3 and the mixing tank 5 respectively to increase stability, and the plug plate 403 is driven by the hydraulic cylinder 405 to move forward and backward inside the slot 402. When the plug plate 403 is completely placed inside the slot 402, the feed hole 401 is blocked, and the sample inside the mixing tank 5 cannot enter the storage tank 3. When the plug plate 403 is pulled out from the slot 402, the mixing tank 5 and the storage tank 3 are restored to a connected state, and normal material discharge can be performed, which is convenient for controlling the material discharge of the mixing tank 5. In addition, the storage tank 3 and the mixing tank 5 are used in combination. When the feed hole 401 is closed, the storage tank 3 and the mixing tank 5 can operate at the same time, thereby improving processing efficiency.

[0046] Furthermore, the sample delivery component includes a feed pipe 6, which is fixedly mounted on the base 1 through a support leg 101, a feed port 601 is provided at one end of the top of the feed pipe 6, and the feed port 601 is communicated with the lower port of the storage tank 3, a discharge port 602 is provided at one end of the bottom of the feed pipe 6, second bearings 603 are fixedly mounted at both ends of the feed pipe 6, a spiral conveying rod 604 is fixedly mounted between the inner rings of the two second bearings 603, a second drive motor 605 is fixedly mounted at one end of the outer wall of the feed pipe 6, and the output shaft of the second drive motor 605 is fixedly connected to one end of the spiral conveying rod 604; the sampling component includes a third drive motor fixedly mounted on the support leg 101 Machine 7, a mounting plate 701 is fixedly connected to the output shaft of the third drive motor 7, a weighing sensor 702 is fixedly installed on the mounting plate 701, a quantitative cup 703 is fixedly installed on the weighing sensor 702, the upper part of the quantitative cup 703 is open, and the quantitative cup 703 is located directly below the discharge port 602; the control component includes a controller 10, the controller 10 can select a PLC controller, and its model is 6ES72350KD220XA8, and the controller 10 has a control button, and the controller 10 is electrically connected to the hydraulic cylinder 405, the first drive motor 501, the second drive motor 605, the third drive motor 7 and the weighing sensor 702 respectively.

[0047] Through the above technical solution, the second drive motor 605 drives the spiral conveying rod 604 to rotate slowly, so that the fine-grained solid medium inside the conveying pipe 6 is pushed out from the discharge port 602 for discharge. The fine-grained solid medium falling from the discharge port 602 falls into the quantitative cup 703. When the weight of the fine-grained solid medium inside the quantitative cup 703 reaches the set value, the weighing sensor 702 transmits a signal to the controller 10. The controller 10 controls the second drive motor 605 to stop outputting the discharge, and at the same time controls the third drive motor 7 to drive the quantitative cup 703 to flip and discharge, so that quantitative sampling can be completed quickly.

[0048] Furthermore, the discharge port 602 is in the shape of a circular tube, and the diameter of the tube opening is smaller than the diameter of the quantitative cup 703 .

[0049] Through the above technical solution, the fine-grained solid medium falling from the discharge port 602 can accurately fall into the quantitative cup 703.

[0050] Furthermore, the third driving motor 7 drives the quantitative cup 703 to rotate by 180° each time.

[0051] Through the above technical solution, the mouth of the quantitative cup 703 can be completely downward, thereby increasing the falling rate of the fine particle solid medium inside the quantitative cup 703.

[0052] Furthermore, a discharge track 8 is fixedly mounted on the base 1 , and the quantitative cup 703 is located directly above the upslope of the discharge track 8 .

[0053] The above technical solution makes it convenient to collect the quantitatively falling fine-grained solid media.

[0054] Furthermore, a connecting rod 704 is fixedly connected to the bottom of the feeding pipe 6 , a third bearing 705 is fixedly mounted on the connecting rod 704 , and an output shaft of the third driving motor 7 is fixedly mounted in an inner ring of the third bearing 705 .

[0055] Through the above technical solution, the stability of the output of the third drive motor 7 can be further increased.

[0056] Furthermore, both the storage tank 3 and the mixing tank 5 are provided with observation windows 9 .

[0057] Through the above technical solution, the inventory of fine particle solid medium and the degree of mixing inside the storage tank 3 and the mixing tank 5 can be easily observed, which is helpful for the implementation of this utility model.

[0058] As is well known to those skilled in the art, the working principles and wiring methods of the hydraulic cylinder 405, the first drive motor 501, the second drive motor 605, the third drive motor 7, the weighing sensor 702 and the controller 10 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can select their models arbitrarily according to their needs or convenience.

[0059] In summary, the workflow of the utility model is:

[0060] When in use, different types of fine-grained solid media are introduced into the interior of the mixing tank 5 from the lower hopper 504, and then the control button on the controller 10 is pressed to control the first drive motor 501 to drive the stirring rod 503 to rotate at a high speed, so that the different fine-grained solid media in the mixing tank 5 are quickly stirred and mixed. When the fine-grained solid media in the mixing tank 5 are mixed, the control button on the controller 10 is pressed to control the hydraulic cylinder 405 to drive the plug plate 403 to be pulled out from the slot 402, and the mixing tank 5 and the storage tank 3 are restored to the connected state, and the material can be discharged normally. The mixed fine-grained solid media are accumulated in the storage tank 3. When the second drive motor 501 is pressed, the mixing tank 5 is cooled and the mixing tank 5 is cooled. When the machine 605 drives the spiral conveying rod 604 to rotate slowly, the fine-grained solid medium in the storage tank 3 enters the interior of the conveying pipe 6 from the feed port 601, and is pushed out from the inside of the discharge port 602 as the spiral conveying rod 604 conveys, and the fine-grained solid medium falling from the discharge port 602 falls into the inside of the quantitative cup 703. When the weight of the fine-grained solid medium in the quantitative cup 703 reaches the set value, the weighing sensor 702 transmits a signal to the controller 10, and the controller 10 automatically controls the second drive motor 605 to stop outputting the material, and at the same time drives the third drive motor 7 to drive the quantitative cup 703 to turn 180° to discharge the material, so that the quantitative sampling can be completed quickly.
