Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural and livestock product quality testing technology, and in particular to a rotary testing device for the viscosity of liquids in agricultural and livestock products. Background Technology
[0002] Agricultural and livestock products, including milk, honey, and feed slurry, have viscosity that is an important parameter for measuring certain standards during production and processing. For example, the viscosity of milk decreases as the degree of spoilage increases, which can be used to detect the freshness of milk. The viscosity of the slurry also needs to be controlled during cheese processing. The viscosity of honey increases significantly when the water content is low, which can be used to judge the maturity of honey.
[0003] Existing rotational viscometers are mostly designed for laboratory environments, employing precision motors and torque sensors. However, they suffer from the following problems: 1. During operation, the height of the viscometer unit needs to be repeatedly adjusted up and down, and leveling may be required after the unit is moved. This is particularly inefficient when dealing with a large quantity of agricultural and livestock products, requiring sample changes or cleaning; 2. The transmission components of the lifting mechanism (commonly such as lead screws and nuts, gear meshing surfaces) are prone to wear and tear over long-term use, leading to reduced lifting and positioning accuracy. Furthermore, vibrations or torque fluctuations generated during motor operation are transmitted to the rotor through these gaps, causing rotor position shifts or wobbling during measurement, directly affecting the accuracy of torque signal acquisition. Therefore, to address these issues, a rotary viscometer for detecting the viscosity of liquids in agricultural and livestock products is proposed to meet the needs of practical applications.

[0022] Example 1
[0023] The rotary viscosity testing device for agricultural and livestock products provided in this embodiment keeps the viscometer main unit 1 in one position and measures the viscosity value by changing the position of the container. This avoids repeated adjustments to the height of the main unit and avoids errors caused by gaps in the transmission components. As shown in the figure, this utility model includes a viscometer main unit 1, a rigid support rod 2, a main unit base 3, a horizontal knob 4, a lifting seat 5, and a sample container 6. The rigid support rod 2 is fixed to the main unit base 3, the viscometer main unit 1 is fixed to the top of the rigid support rod 2, the horizontal knob 4 is threaded to the bottom of the main unit base 3, and the lifting seat 5 is movably connected to... The sample container 6 is placed on the lifting seat 5 on the rigid support rod 2; the viscometer main unit 1 includes an operation panel 11, a rotor connector 12, a rotor body 13, a rotor protection frame 14, a power switch 15, and a level 16. The rotor connector 12 is located on the front of the viscometer main unit 1 and is rotatably connected to the bottom of the viscometer main unit 1. The rotor body 13 is detachably connected to the bottom of the rotor connector 12. The rotor protection frame 14 is fixedly connected to the bottom of the viscometer main unit 1. The power switch 15 is located on the back of the viscometer main unit 1, and the level 16 is located on the top of the viscometer main unit 1.
[0024] In this embodiment, the device must be checked and calibrated before operation: After turning off the power switch 15, check whether the level 16 and rotor protection frame 14 of the device are intact, and select the rotor body 13 that conforms to the ISO standard according to the characteristics of the liquid being measured. Insert it vertically into the rotor connector 12 below the viscometer main unit 1 and lock it. Then, by adjusting the level knob 4 of the main unit base 3, ensure that the bubble of the top level 16 is centered, so that the device is in a horizontal state to reduce measurement errors. The sample needs to be placed in the sample container 6 and placed on the lifting seat 5. The liquid level should be 10-15mm lower than the container opening and allowed to stand to defoam.
[0025] At the start of the measurement, the operator needs to vertically adjust the height of the sample container 6 using the lifting seat 5, ensuring a 5-10mm gap between the rotor body 13 immersed in the liquid and the bottom of the container to avoid contact with the container wall. After setting parameters such as temperature and rotation speed via the operation panel 11, the power is turned on. Real-time data is acquired based on changes in torque value, and the data is recorded after the value stabilizes. After the measurement is completed, the power should be turned off before removing the rotor for cleaning. A special cleaning agent should be used to treat any residual liquid to protect the measurement surface. The final data needs to be converted using a preset formula and analyzed in conjunction with the temperature curve.
[0026] Example 2
[0027] Based on Example 1, such as Figure 3-4 As shown, the lifting seat 5 in this embodiment includes a container support 51, a sliding rod 52, an external thread 53, and a threaded sleeve 54. The container support 51 is fixed to one end of the sliding rod 52, the external thread 53 is integrally formed on the other end of the sliding rod 52, and the threaded sleeve 54 is threadedly connected to the surface of the external thread 53. A positioning groove 21 matching the diameter of the sliding rod 52 is provided on the rigid support rod 2, and the side of the rigid support rod 2 is in contact with one side of the container support 51.
[0028] In this embodiment, the container holder 51 serves as a support platform for the sample container 6 and is rigidly connected to one end of the sliding rod 52 by welding. The sliding rod 52 is made of stainless steel, and its diameter matches the positioning groove 21 on the rigid support rod 2. The container holder 51 can be fixed to one side of the rigid support rod 2 using a threaded sleeve 54.
[0029] Among them, the surface of the threaded sleeve 54 is integrally formed with anti-slip protrusions 57, which can increase the friction of manually rotating the threaded sleeve 54.
[0030] The threaded end of the sliding rod 52 is integrally formed with an anti-disengagement post 56, which can prevent the threaded sleeve 54 from disengaging from the external thread 53.
[0031] Example 3
[0032] Based on Example 2, such as Figure 4 As shown, the top of the container holder 51 in this embodiment is provided with a cylindrical groove 58. The cylindrical groove 58 is cylindrical, and the diameter of the cylindrical groove 58 matches that of the sample container 6.
[0033] In this embodiment, by creating a cylindrical groove 58 of a certain depth, the stability of the sample container 6 after placement can be increased.
[0034] Example 4
[0035] Based on Example 3, such as Figure 4As shown, the bottom of the cylindrical groove 58 in this embodiment is provided with ventilation holes 510, and the number of ventilation holes 510 is several. The inner wall of the cylindrical groove 58 is provided with a protective layer 59, which is annular.
[0036] In this embodiment, to prevent the bottom of the sample container 6 from sticking to the cylindrical groove 58 due to sealing, the air pressure is balanced through the vent 510. The protective layer 59 reduces the risk of damage caused by collision between the sample container 6 and the container holder 51, while also improving the securing effect of the sample container 6 after placement, preventing it from rotating with the liquid during measurement.
[0037] Example 5
[0038] Based on Example 2, such as Figure 4 As shown, in this embodiment, a locking tooth 55 is integrally formed on one side of the container holder 51, and an anti-slip tooth 22 matching the locking tooth 55 is provided on one side of the rigid support rod 2. The upper and lower sides of the anti-slip tooth 22 are located above and below the positioning groove 21, respectively.
[0039] In this embodiment, the combination of the locking teeth 55 and the anti-slip teeth 22 increases the stability of the container tray 51 after it is fixed. The anti-slip teeth 22 cover a height greater than the length of the positioning groove 21, ensuring the stability of the container tray 51 before and after lifting.
