Description

Technical Field

[0001] The present invention belongs to the technical field related to analysis and detection equipment, and more specifically, relates to an analysis and detection equipment for accurately detecting nutrient mixture. Background Art

[0002] Nutrient mixing analysis and testing equipment measures the content of specific nutrients. This involves placing the test substance and an analytical solution into a test tube and mixing them. Mixing promotes a chemical reaction between the test substance and the analytical solution. Many nutrient tests are based on specific chemical reactions. Even mixing allows the reactants to fully contact, improving the completeness of the reaction and thus making the test results more reliable. However, existing analytical testing equipment has the following drawbacks: In the prior art, when shaking the solution in the test tube to mix it, the elasticity of the ordinary clamp may gradually weaken as the shaking time increases or the shaking force increases, resulting in a decrease in the clamping force on the test tube. As a result, the test tube may become loose or even fall off during the shaking process, affecting the normal progress of the experiment. In the prior art, when a test tube solution is oscillated to mix the solution, simple clamping is unable to effectively resist the effects of vibration. Due to the lack of a stable support structure and buffer mechanism, the vibration may cause the relative position between the clamp and the test tube to shift, further weakening the clamping effect, causing the test tube to shake more during the oscillation process, which is not conducive to uniform mixing of the solution. In the prior art, when the test tube oscillates, the impact force generated by the oscillating device is directly transmitted to the test tube. Since there is no buffer to disperse or absorb this energy, the test tube may be subjected to greater stress. Especially during high-frequency or violent oscillations, this stress can easily cause the test tube to rupture or loosen the connection between the clamp and the test tube, thereby affecting the stability of the entire device.

[0003] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a nutrient mixture analysis and detection device with accurate detection is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0032] Preferably, refer to the attached Figure 4 A test tube placement slot 18 is placed below the oscillation mixing device 19. The test tube placement slot 18 is used to store test tubes.

[0033] Preferably, refer to the attached Figure 4 An analysis device 12 and a recovery device 13 are also fixedly installed above the operating table 11. The analysis device 12 is arranged on the left side of the recovery device 13, and the analysis device 12 and the recovery device 13 are arranged in front of the test tube oscillation device 14.

[0034] Specific use of the present invention: When using the device, first, connect the power supply of the device, place the test tube of the food testing solution next to the device, and then place the test tube to be tested on the test tube storage rack 21. Then start the device, and the oscillation mixing device 19 of the device will automatically clamp the test tube and oscillate and mix it.

[0035] During operation, the drive motor 26 in the oscillating and mixing device 19 first rotates the first fixed pulley 24 via a synchronous belt, simultaneously raising or lowering the oscillating and rocking device 25. As the oscillating and rocking device 25 descends, it lowers the clamping and adjusting assembly 37 to clamp the test tube. When the clamping and adjusting assembly 37 is ready to clamp a test tube, the third rotary motor 45 within the clamping and adjusting assembly 36 drives the two sets of clamping and adjusting assemblies 37 toward or away from each other. To clamp, the third rotary motor 45 moves the two sets of clamping end blocks 46 toward each other; to release, the opposite operation is performed.

[0036] After the clamping and adjusting assembly 37 initially clamps the test tube, the first rotary motor 34 starts to rotate to shake and mix the clamping and adjusting assembly 37. However, when the first rotary motor 34 shakes the clamping and adjusting assembly 37, the test tube may be thrown out, causing problems such as test failure and environmental pollution.

[0037] To address this issue, the airbag protection assembly 67 within the clamping and adjusting assembly 37 activates when the first rotary motor 34 drives the clamping and adjusting assembly 37 to oscillate and swing. As the clamping and adjusting assembly 37 oscillates, the counterweight slider 51 within the slide cavity 66 slides left and right within the slide cavity 66. As the counterweight slider 51 slides, it pushes the first piston plates 55 on either side via the guide rods 54, compressing the air chambers. The left-right sliding of the first piston plates 55 alternates the inflation chambers, and the air in the inflation chambers flows through the one-way control valves into the side airbags 41, the upper suction cup protection assembly 40, and the telescopic bottom support protection assembly 43.

[0038] After the gas enters the side bladder 41, it inflates and wraps around the outside of the test tube. Furthermore, the longer the clamping adjustment assembly 37 is shaken, the tighter the inflated side bladder 41 grips the test tube. Simultaneously, the inflation chamber of the second inflation assembly 53 inflates the upper suction cup protection assembly 40. The air pressure pushes the second piston plate 59, which in turn pushes the curved rubber stopper 61 to squeeze and wrap around the upper end of the test tube.

[0039] In addition, when the inflation chamber at one end of the first inflatable component 52 is inflated, the gas enters the side bag 41 and the telescopic bottom protection component 43. The gas first enters the cavity between the fixed shell 62 of the telescopic bottom protection component 43 and the first-stage telescopic airbag 63, pushing out the first-stage telescopic airbag 63; then the cavity between the first-stage telescopic airbag 63 and the second-stage telescopic airbag 64 is inflated, pushing out the second-stage telescopic airbag 64; after the second-stage telescopic airbag 64 is filled with gas, it is discharged into the arc-shaped expansion body 65. When the first-stage telescopic airbag 63, the second-stage telescopic airbag 64, and the arc-shaped expansion body 65 are inflated and extended, they form a semi-enclosed protection for the test tube together with the upper suction cup protection component 40. Because there are two clamping adjustment components 37, the upper suction cup protection component 40, the side bag 41, and the telescopic bottom protection component 43 between them can achieve full protection for the test tube, and the longer the test tube is shaken, the tighter the wrapping force.

[0040] After the shaking is completed, the electrically controlled pressure relief valve in the clamping adjustment assembly 37 relieves pressure on the upper suction cup protection assembly 40, the telescopic bottom protection assembly 43 and the side bag 41 to recover the test tube, so that the test tube returns to its original clamping state. Afterwards, the second rotary motor 38 adjusts the direction of the test tube and places the test tube into the test tube placement slot 18. Next, the mechanical clamping arm 32 in the test tube displacement clamp 17 takes out the test tube from the test tube placement slot 18, and the driving machine 29 controls the position of the mechanical clamping arm 32 through lifting and lowering drive. After the mechanical clamping arm 32 reaches the appropriate position, it adjusts the lateral angle and places the test tube into the test tube temporary storage rack 31. Finally, the operator takes out the test tube and places it into the analysis device 12 for solution analysis. After the analysis is completed, the tested test tube is placed into the recovery device 13, thus completing the entire detection process.

[0041] The embodiments of the present invention are presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art.
