Description

Technical Field

[0001] This utility model relates to the field of dairy product testing technology, and in particular to a sampling device for testing special milk. Background Technology

[0002] In the field of dairy production and quality control, especially in the quality monitoring stages of fresh milk acquisition, entry inspection and production, accurate and representative sampling of raw milk or semi-finished products is the first key step to ensure the validity of test results and the safety of the final product.

[0003] A search of Chinese patent CN217738759U reveals a fully automatic milk testing sampling device, relating to the field of milk production equipment technology. The device includes a connecting frame, and further comprises: movable wheels connected to the connecting frame; a lateral movement mechanism connected to the connecting frame; a second driving component connected to the lateral movement mechanism; a connecting plate connected to the output end of the second driving component; a first telescopic component connected at one end to the connecting plate; a sampling mechanism connected at one end to the other end of the first telescopic component and at the other end to the connecting frame; and a stirring mechanism connected to the sampling mechanism. This patent utilizes the lateral movement mechanism to drive the second driving component to move laterally, which in turn drives the first telescopic component to rotate. The first telescopic component then drives the sampling mechanism to rotate, allowing the sampling mechanism to sample the milk. The sampling mechanism also drives the stirring mechanism to rotate, thus stirring the milk. This solves the problem of existing sampling devices failing to stir the milk properly, resulting in uneven milk composition and affecting test results.

[0004] Based on the above search results and existing technologies, the following findings were made: Existing automated milk sampling devices mostly employ a fixed-depth, single-point sampling mode, which cannot overcome the stratification phenomenon caused by fat rising to the surface and uneven composition after the milk has been left to stand. This results in severely distorted samples that are difficult to represent the overall true composition. This problem is particularly prominent in the testing of high-value specialty milk products that are sensitive to stratification, directly impacting the accuracy and fairness of quality inspection. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a sampling device for special milk testing, which is equipped with multiple inlet pipes and sampling chambers, enabling the collection of samples from different locations for diverse comparisons and further improving the testing effect.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a sampling device for special milk detection, including a base, a mounting frame installed on the base, a mounting plate installed on the top of the mounting frame, a stirring mechanism provided on the mounting plate, the stirring mechanism including a drive motor, a stirring shaft and a stirring rod, the drive motor being fixedly installed on the end of the mounting plate away from the mounting frame, the stirring shaft being fixedly installed on the output end of the drive motor, the stirring rod being fixedly installed on the side wall of the stirring shaft, and a sampling mechanism being provided on the stirring shaft; The sampling mechanism includes multiple sampling chambers and inlet pipes. The multiple sampling chambers are evenly distributed inside the stirring shaft. The inlet pipes are all fixedly installed on the side wall of the stirring shaft at the positions corresponding to the sampling chambers, and the inlet pipes are connected to the upper interior of the sampling chambers. An outlet pipe is also fixedly installed on the side wall of the stirring shaft at the position corresponding to the sampling chambers, and the outlet pipe is also connected to the interior of the inlet pipe.

[0007] In some embodiments, the sampling mechanism further includes a one-way valve, a piston plate, and a transmission rod. There are multiple one-way valves, which are fixedly installed on multiple inlet and outlet pipes respectively. The piston plate is movably installed inside the sampling chamber, and the transmission rod is located inside the stirring shaft and fixedly connected to the multiple piston plates.

[0008] In some embodiments, the one-way valve allows the inlet tube to allow the sample to enter the sampling chamber from the outside but not to leave the sampling chamber through the inlet tube, while allowing the outlet tube to allow the sample to leave the sampling chamber from the inside but not to enter the sampling chamber through the outlet tube.

[0009] In some embodiments, the mounting plate is provided with a drive mechanism, which includes an electric telescopic rod. A push rod is installed on the output end of the electric telescopic rod, and the push rod penetrates downward through the upper and lower walls of the mounting plate.

[0010] In some embodiments, a movable groove is provided above the side wall of the stirring shaft, and a connecting seat is movably sleeved on the stirring shaft at the position corresponding to the movable groove. A connecting rod is fixedly connected between the connecting seat and the transmission rod.

[0011] In some embodiments, a limiting block is movably mounted inside the connecting seat, and the bottom of the push rod is fixedly connected to the limiting block.

[0012] Compared with existing technologies, the significant advantages of this invention are: In this invention, when the stirring shaft is inside the sample, it can be driven downward by the piston plate via the transmission rod, generating suction inside the sampling chamber. At this time, the sample can be drawn into the sampling chamber through the inlet pipe. Then, the stirring shaft can be removed from the container, and the sampling container can be placed at the outlet pipe position. Subsequently, the transmission rod drives the piston plate upward, which squeezes the sample inside the sampling chamber, allowing the sample to be collected by the sampling container through the outlet pipe. Furthermore, since multiple inlet pipes and sampling chambers are provided, samples can be collected from different locations, enabling diverse comparisons and further improving the detection effect.

[0015] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0016] This utility model provides an improved sampling device for detecting special milk. The technical solution of this utility model is as follows: like Figures 1 to 3 As shown, a special milk testing sampling device includes a base 1, a mounting frame 2 mounted on the base 1, a mounting plate 3 mounted on the top of the mounting frame 2, and a stirring mechanism mounted on the mounting plate 3. The mounting frame 2 can be driven to move up and down, thereby driving the stirring mechanism to move up and down, thus adapting to sampling work at different positions. The stirring mechanism includes a drive motor 4, a stirring shaft 5, and stirring rods 6. The drive motor 4 is fixedly mounted on the mounting plate 3 at one end away from the mounting frame 2. The stirring shaft 5 is fixedly mounted on the output end of the drive motor 4 and located below the mounting plate 3. There are multiple stirring rods 6, which are evenly distributed and fixedly mounted on the side wall of the stirring shaft 5. A sampling mechanism is provided on the stirring shaft 5. During sampling, the stirring shaft 5 is inserted into the container containing the sample. First, the drive motor 4 is started, which drives the stirring shaft 5 and stirring rods 6 to rotate. The rotation of the stirring rods 6 can stir the sample inside the container evenly, making the internal components of the sample more uniform and ensuring the detection effect.

[0017] The sampling mechanism includes sampling chambers 7 and inlet pipes 8. Sampling chambers 7 are cylindrical cavities, and there are multiple sampling chambers 7, evenly distributed inside the stirring shaft 5. The inlet pipes 8 are tubular structures, and the number of inlet pipes 8 matches the number of sampling chambers 7. Multiple inlet pipes 8 are fixedly installed on the side wall of the stirring shaft 5 at positions corresponding to the sampling chambers 7, and are connected to the upper interior of the sampling chambers 7. Multiple outlet pipes 9 are also fixedly installed on the side wall of the stirring shaft 5 at positions corresponding to the sampling chambers 7. The outlet pipes 9 are also tubular structures and are also connected to the interior of the inlet pipes 8. When the stirring shaft 5 is inside the sample, the sample can be drawn into the sampling chambers 7 through the inlet pipes 8, thus achieving the sampling effect. Furthermore, due to the presence of multiple inlet pipes 8 and sampling chambers 7, samples from different locations can be collected, allowing for diverse comparisons and further improving the detection effect.

[0018] The sampling mechanism also includes a one-way valve 10, a piston plate 11, and a transmission rod 12. Multiple one-way valves 10 are fixedly installed on multiple inlet pipes 8 and outlet pipes 9. The one-way valves 10 ensure that the sample can only enter the sampling chamber 7 from the outside through the inlet pipe 8 and cannot leave the sampling chamber 7 through the inlet pipe 8. Similarly, the sample can only leave the sampling chamber 7 from the inside through the outlet pipe 9 and cannot enter the sampling chamber 7 through the outlet pipe 9. The piston plate 11 is a circular plate and is movably installed inside the sampling chamber 7. The transmission rod 12 has a cylindrical structure and is designed to... The sample is placed inside the stirring shaft 5 and fixedly connected to multiple piston plates 11. The piston plates 11 can be moved inside the sampling chamber 7 by the transmission rod 12. When the piston plates 11 are moved downward by the transmission rod 12, a suction force is generated inside the sampling chamber 7. At this time, the sample can be sucked into the sampling chamber 7 through the liquid inlet pipe 8. Then the stirring shaft 5 can be removed from the container. Subsequently, the sampling container can be placed at the position of the liquid outlet pipe 9. Then the transmission rod 12 drives the piston plates 11 to move upward. The piston plates 11 can squeeze the sample inside the sampling chamber 7, so that the sample can be collected by the sampling container through the liquid outlet pipe 9.

[0019] The mounting plate 3 is equipped with a drive mechanism, which includes an electric telescopic rod 13. A push rod 14 is installed on the output end of the electric telescopic rod 13. The push rod 14 passes through the upper and lower walls of the mounting plate 3. A movable groove 15 is provided above the side wall of the stirring shaft 5. The movable groove 15 is a rectangular groove. A connecting seat 16 is movably sleeved on the stirring shaft 5 at the position corresponding to the movable groove 15. The connecting seat 16 is a hollow circular structure. A connecting rod 17 is fixedly connected between the connecting seat 16 and the transmission rod 12. A limiting block 18 is movably installed inside the connecting seat 16. The bottom of the push rod 14 is fixedly connected to the limiting block 18. Through the setting of the drive mechanism, when the stirring shaft 5 rotates, the connecting seat 16 and the connecting rod 17 can rotate with the stirring shaft 5. The push rod 14 and the limiting block 18 will remain in place to limit the connecting seat 16. The limiting block 18 is located inside the connecting seat 16 to limit the connecting seat 16. When the stirring shaft 5 stops rotating, the electric telescopic rod 13 can be activated. The electric telescopic rod 13 drives the connecting seat 16 to move through the push rod 14. The connecting seat 16 can then drive the transmission rod 12 to move through the connecting rod 17, thereby enabling sampling work.

[0020] The specific working method is as follows: During sampling, the stirring shaft 5 is inserted into the container containing the sample. First, the drive motor 4 is started. The drive motor 4 drives the stirring shaft 5 and the stirring rod 6 to rotate. The rotation of the stirring rod 6 can stir the sample inside the container evenly, making the composition inside the sample more uniform and ensuring the detection effect. When the stirring shaft 5 is inside the sample, it can be driven downward by the piston plate 11 and the transmission rod 12 to generate suction inside the sampling chamber 7. At this time, the sample can be sucked into the sampling chamber 7 through the liquid inlet pipe 8. Then, the stirring shaft 5 can be removed from the container. Subsequently, the sampling container can be placed at the position of the liquid outlet pipe 9. Then, the transmission rod 12 drives the piston plate 11 to move upward. The piston plate 11 can squeeze the sample inside the sampling chamber 7, so that the sample can be collected by the sampling container through the liquid outlet pipe 9. At the same time, since multiple liquid inlet pipes 8 and sampling chambers 7 are provided, samples from different positions can be collected, thereby making diverse comparisons and further improving the detection effect.
