Description

Technical Field

[0001] The present invention relates to the technical field of mixing, and particularly relates to an ultra-low temperature bovine straw frozen semen diluent and a processing device therefor. Background Art

[0002] Bovine straw frozen semen dilution refers to a technique used in the cryopreservation of bovine semen, aiming to protect sperm cells from damage during the freezing and thawing processes by adding specific diluents (or "dilution solutions"). This process is crucial for improving the survival rate and motility of sperm after cryopreservation.

[0003] When adding a dilution solution to semen for mixing, since sperm cells are very fragile, stirring should be gentle and slow to avoid mechanical damage to the sperm. Moreover, temperature consistency usually needs to be considered during stirring. A gentle stirring method can help maintain the required temperature and avoid temperature fluctuations from damaging the sperm. However, the conventional method of rotational stirring using a stirrer generates shear forces that cause strong interactions between liquid molecules and easily lead to temperature rise. Summary of the Invention

[0004] To overcome the technical drawbacks presented in the above background art, the present invention provides an ultra-low temperature bovine straw frozen semen diluent and a processing device therefor.

[0005] An ultra-low temperature bovine straw frozen semen diluent and a processing device therefor include a frame. A first motor is fixedly connected to the frame. The output shaft of the first motor is fixedly connected to a rotating frame. A mixing cylinder is placed on the rotating frame. The mixing cylinder is made of a heat-conducting material. Cylinders symmetrically distributed along the frame are fixedly connected to the frame. A first fixing frame is fixedly connected between the telescopic rods of the symmetrically distributed cylinders. The first fixing frame is provided with a connecting ring. A main stirrer is magnetically levitated inside the ring near the connecting ring. The main stirrer is fixedly connected with circumferentially distributed first magnets. The connecting ring is fixedly connected with circumferentially distributed second magnets. The first magnets are magnetically coupled with adjacent second magnets.

[0006] Further, it further includes a second fixing frame. The second fixing frame is fixedly connected to the first fixing frame. A second motor is fixedly connected to the second fixing frame. The output shaft of the second motor is fixedly connected to a gear. The connecting ring is rotatably connected to the first fixing frame. The connecting ring is provided with an annular tooth groove meshing with the gear. The connecting ring is fixedly connected with circumferentially distributed guide rods. A lifting frame is slidably connected to the first fixing frame. The lifting frame is provided with circumferentially distributed guide grooves. The guide rods are slidably connected with adjacent guide grooves. When the guide rods rotate, the lifting frame is driven to slide downward through the guide grooves. The lifting frame is fixedly connected with circumferentially distributed third magnets. A sub-stirrer is slidably connected inside the main stirrer. The sub-stirrer is fixedly connected with circumferentially distributed fourth magnets. The fourth magnets are magnetically coupled with adjacent third magnets.

[0007] Furthermore, both the main stirrer and the auxiliary stirrer are set to be Y-shaped.

[0008] Furthermore, a temperature sensor is also included. The temperature sensor is fixedly connected to the first fixing frame and is used to detect the temperature of the semen.

[0009] Furthermore, the temperature sensor is electrically connected to the second motor through a control module.

[0010] Furthermore, a plurality of blades are included, which are arranged obliquely in the circumferential direction. The blades are fixedly connected to the rotating frame. A filter screen is fixedly connected to one side of the frame close to the rotating frame, and a gas guide ring for guiding natural wind to the mixing cylinder is fixedly connected to one side of the frame close to the filter screen.

[0011] Furthermore, a storage cylinder is also included. The storage cylinder is fixedly connected to the upper part of the frame. A fixed rod is slidably connected to the cylinder fixing part on one side, and the fixed rod is fixedly connected to the first fixing frame. A switching pipe is rotatably connected to the lower part inside the storage cylinder. The switching pipe and the storage cylinder are both provided with the same through holes, and the through holes of the switching pipe are misaligned with those of the storage cylinder. A sliding frame for pushing and pulling the switching pipe to rotate is slidably connected to the storage cylinder. A spring is fixedly connected between the storage cylinder and the sliding frame. A rotating plate is rotatably connected to one side of the sliding frame close to the fixed rod, and when the fixed rod moves downward, it is in pressing cooperation with the rotating plate.

[0012] Furthermore, a protrusion is provided on one side of the fixed rod close to the rotating plate, and the lower side of the protrusion is in pressing cooperation with the rotating plate through a wedge-shaped surface.

[0013] Furthermore, the sliding frame is provided with a movable groove, and the sliding frame is movably connected to the switching pipe through the movable groove.

[0014] Furthermore, a magnetic ring is also included, which is fixedly connected to the bottom of the first fixing frame.

[0015] Compared with the prior art, the present invention has the following advantages: In the present invention, the mixing cylinder rotates instead of the main stirrer, and the main stirrer oscillates slightly up and down, so that the semen and the diluent are gently and slowly mixed sufficiently, reducing the shear force on sperm cells and the risk of potential physical mechanical damage, and is more suitable for processing bovine straw frozen semen, which is sensitive to mechanical stress. In addition, the non-rotation of the main stirrer means less heat generated by friction, and magnetic stirring also reduces the energy loss and heat generation caused by mechanical transmission, which is beneficial to maintaining a more stable temperature environment and improving the activity of sperm.

[0016] The present invention detects the temperature of the semen through a temperature sensor, and controls the second motor to drive the extension and retraction of the auxiliary stirrer through a control module, achieving the effect of temperature control and adjusting the stirring area, taking into account both the mixing efficiency and the frictional heat.

[0017] The present invention utilizes the guiding action of the air guiding ring to enable the natural wind to flow upward along the outer wall of the mixing cylinder, thereby cooling the mixing cylinder. In this way, the temperature of the mixed liquid is further reduced, and the effect of low-temperature mixing of semen and diluent is improved.

[0018] Through the extrusion cooperation between the protrusion of the first fixing frame and the rotating plate, the present invention realizes the effect of automatically adding a quantitative diluent during the downward stirring process, without the need for manual control of the addition amount of the diluent, and can ensure that no diluent is added during the upward reset after the stirring is completed.

[0019] The present invention enables the dropped main stirrer and auxiliary stirrer to be suspended at the magnetic ring by the magnetic ring magnetically attracting the second magnet for the second time, avoiding the main stirrer and auxiliary stirrer from falling to the bottom of the mixing cylinder. Moreover, when the main stirrer and auxiliary stirrer still fall to the bottom of the cylinder, the main stirrer and auxiliary stirrer are lifted upward by the magnetic attraction force between the magnetic ring and the second magnet.

Detailed implementation manners

[0032] The present invention will be further described below with reference to the drawings and embodiments.

[0033] Embodiment 1: A cryopreservation diluent for bovine fine straw semen and a processing device, as shown in Figure 1 - Figure 4, including a frame 101, a first motor 102 is fixedly connected to the lower part of the frame 101, an output shaft of the first motor 102 is fixedly connected to a rotating frame 103, a mixing cylinder 104 is placed in the rotating frame 103 through a placement groove, the mixing cylinder 104 is made of a heat-conducting material, cylinders 105 symmetrically distributed left and right along the frame 101 are fixedly connected to the upper part of the frame 101, a first fixing frame 106 is fixedly connected between the telescopic rods of the symmetrically distributed cylinders 105 left and right, a connecting ring 107 is arranged at the lower part of the first fixing frame 106, a main stirrer 108 is magnetically levitated inside the ring close to the connecting ring 107, three first magnets 109 evenly distributed at equal circumferential intervals are fixedly connected to the main stirrer 108, six second magnets 110 evenly distributed at equal circumferential intervals are fixedly connected to the inner wall of the connecting ring 107, and the first magnet 109 is magnetically coupled with the adjacent second magnet 110.

[0034] When using this device to mix semen and diluent, first, an appropriate amount of semen and diluent are added into the mixing cylinder 104, then the first motor 102 is started, the output shaft of the first motor 102 drives the mixing cylinder 104 to rotate through the rotating frame 103, then, the telescopic rods of the cylinders 105 are controlled to extend downward, thereby driving the first fixing frame 106, the connecting ring 107 and the first magnet 109 to move downward as a whole, the first magnet 109 drives the second magnet 110 to move downward through magnetic attraction, and the second magnet 110 drives the main stirrer 108 to move downward synchronously, so that the main stirrer 108 enters the inner bottom of the mixing cylinder 104, and the connecting ring 107 is sleeved outside the mixing cylinder 104.

[0035] Next, the telescopic rod of the control cylinder 105 is intermittently extended and retracted slightly up and down, so that the main stirrer 108 moves intermittently up and down in the mixing cylinder 104, thereby causing the mixed liquid of semen and diluent to oscillate slightly up and down. After complete mixing, the control cylinder 105 is retracted upward to reset, so that the first fixing frame 106, the connecting ring 107, the first magnet 109 and the main stirrer 108 move upward as a whole to reset, and the first motor 102 is controlled to turn off.

[0036] In this way, in the present invention, the mixing cylinder 104 is used to replace the rotation of the main stirrer 108, and the main stirrer 108 oscillates slightly up and down, so that the semen and the diluent are gently and slowly mixed sufficiently, reducing the shear force on sperm cells and the risk of potential physical mechanical damage. It is more suitable for processing bovine straw frozen semen, which is sensitive to mechanical stress. In addition, the non-rotation of the main stirrer 108 means less heat generated by friction, and magnetic stirring also reduces the energy loss and heat generation caused by mechanical transmission, which is beneficial to maintaining a more stable temperature environment and improving the activity of sperm.

[0037] Embodiment 2: On the basis of Embodiment 1, as Figure 5 shown in - Figure 7, it further includes a second fixing frame 201. The second fixing frame 201 is fixedly connected to the first fixing frame 106. A second motor 202 is fixedly connected to the second fixing frame 201. A gear 2021 is fixedly connected to the output shaft of the second motor 202. The connecting ring 107 is rotatably connected to the first fixing frame 106. An annular tooth groove meshing with the gear 2021 is formed on the outer wall of the connecting ring 107. Guide rods 203 distributed circumferentially are fixedly connected to the top of the connecting ring 107. A lifting frame 204 is slidably connected to the upper part of the first fixing frame 106 in the up and down direction. Guide grooves distributed circumferentially are formed in the lifting frame 204. The guide rods 203 are slidably connected to the adjacent guide grooves. When the guide rods 203 rotate, the lifting frame 204 is driven to slide downward through the guide grooves. Six third magnets 205 evenly distributed circumferentially are fixedly connected to the top of the lifting frame 204. A sub-stirrer 206 is slidably connected to the main stirrer 108 in the up and down direction. Both the main stirrer 108 and the sub-stirrer 206 are arranged in a Y shape. Three fourth magnets 207 distributed circumferentially are fixedly connected to the sub-stirrer 206. The fourth magnets 207 are magnetically coupled with the adjacent third magnets 205. A temperature sensor 208 for detecting the temperature of semen is fixedly connected to the top of the first fixing frame 106. The temperature sensor 208 is electrically connected to the second motor 202 through a control module.

[0038] The up-and-down movement of the first fixing frame 106 drives the second fixing frame 201, the second motor 202, the gear 2021, the guide rod 203, the lifting frame 204 and the third magnet 205 to synchronously move up and down. The main stirrer 108 drives the sub-stirrer 206 and the fourth magnet 207 to synchronously move up and down. If the temperature sensor 208 detects that the temperature of the semen is higher than the preset value, the temperature sensor 208 controls the rotation of the output shaft of the second motor 202 through the control module, thereby driving the gear 2021 to rotate. The gear 2021 drives the connecting ring 107 to rotate through the annular tooth groove. The connecting ring 107 drives the guide rod 203 to rotate. The guide rod 203 acts on the guide groove of the lifting frame 204, causing the lifting frame 204 to move downward. The lifting frame 204 drives the third magnet 205 to move downward. The third magnet 205 drives the fourth magnet 207 to move downward through magnetic attraction. The fourth magnet 207 drives the sub-stirrer 206 to slide downward and retract into the main stirrer 108. In this way, the stirring area is reduced at high temperatures, thereby reducing frictional heat.

[0039] If the temperature sensor 208 detects that the temperature of the semen is lower than the preset value, the temperature sensor 208 controls the output shaft of the second motor 202 to rotate in the reverse direction through the control module, thereby driving the gear 2021 to rotate in the reverse direction. The gear 2021 drives the connecting ring 107 to rotate in the reverse direction through the annular tooth groove. The connecting ring 107 drives the guide rod 203 to rotate in the reverse direction. The guide rod 203 acts on the guide groove of the lifting frame 204, causing the lifting frame 204 to move upward. The lifting frame 204 drives the third magnet 205 to move upward. The third magnet 205 drives the fourth magnet 207 to move upward through magnetic attraction. The fourth magnet 207 drives the sub-stirrer 206 to slide upward and extend out of the main stirrer 108. At low temperatures, the stirring area is increased to improve the mixing efficiency.

[0040] In summary, the present invention detects the temperature of the semen through the temperature sensor 208 and controls the extension and retraction of the sub-stirrer 206 by driving the second motor 202 through the control module, achieving the effect of temperature-controlled adjustment of the stirring area and taking into account both the mixing efficiency and the frictional heat.

[0041] As Figure 8 shown, there are also several blades 301 inclined circumferentially. The blades 301 are fixedly connected to the outer wall of the rotating frame 103. A filter screen 302 is fixedly connected to one side of the frame 101 close to the rotating frame 103. A gas guide ring 303 is fixedly connected to one side of the frame 101 close to the filter screen 302. The gas guide ring 303 is used to direct the natural wind to the mixing cylinder 104 to cool the mixing cylinder 104 and thereby cool the semen.

[0042] The temperature of the semen can also conduct heat to the mixing cylinder 104. When the rotating frame 103 rotates, it drives the blades 301 to rotate, causing the air to flow upward from bottom to top to form natural wind. The filter screen 302 filters impurities such as dust in the natural wind. Under the guiding action of the air guiding ring 303, the natural wind flows upward along the outer wall of the mixing cylinder 104, thereby cooling the mixing cylinder 104. In this way, the temperature of the mixed liquid is further reduced, and the effect of low-temperature mixing of semen and diluent is improved.

[0043] Embodiment 3: On the basis of Embodiment 2, as Figure 9 shown in FIGS. 10, it further includes a storage cylinder 401 for storing diluent. The storage cylinder 401 is fixedly connected to the upper part of the frame 101. The fixed part of the cylinder 105 on the right side is slidably connected with a fixed rod 402 in the vertical direction. A protrusion is provided on the lower side of the fixed rod 402. The fixed rod 402 is fixedly connected to the first fixing frame 106. A switching pipe 403 is rotatably connected to the lower part inside the storage cylinder 401. The switching pipe 403 and the storage cylinder 401 are both provided with three identical through holes distributed circumferentially. The through holes of the switching pipe 403 are misaligned with the through holes of the storage cylinder 401. At this time, the diluent cannot be discharged. The lower part of the storage cylinder 401 is slidably connected with a sliding frame 404 in the left-right direction. An activity groove is opened in the front part on the left side of the sliding frame 404. The sliding frame 404 is movably connected with the switching pipe 403 through the activity groove for pushing and pulling the switching pipe 403 to rotate. A spring 405 is fixedly connected between the storage cylinder 401 and the sliding frame 404. A rotating plate 406 is rotatably connected to the right side of the sliding frame 404. When the protrusion on the lower side of the fixed rod 402 moves downward, it is in pressing fit with the rotating plate 406 through a wedge-shaped surface.

[0044] The diluent to be added is placed in the storage cylinder 401 for storage. When the first fixing frame 106 drives the fixed rod 402 to move downward, the fixed rod 402 presses the rotating plate 406 to move leftward through the wedge-shaped surface of the protrusion, thereby pushing the sliding frame 404 to slide leftward. The spring 405 is compressed. The sliding frame 404 pushes the switching pipe 403 to rotate clockwise through the activity groove, so that the through holes of the switching pipe 403 correspond to the through holes of the storage cylinder 401 one by one. At this time, the diluent in the storage cylinder 401 flows into the lower mixing cylinder 104. When the protrusion of the fixed rod 402 driven by the first fixing frame 106 moves downward and disengages from the rotating plate 406, the spring 405 resets and drives the sliding frame 404 to slide rightward. The sliding frame 404 pulls the switching pipe 403 to rotate counterclockwise and reset through the activity groove, so that the through holes of the switching pipe 403 are misaligned with the through holes of the storage cylinder 401, thereby pausing the discharge of the diluent.

[0045] And when the protrusion of the fixed rod 402 moves upward past the rotating plate 406, the protrusion of the fixed rod 402 toggles the rotating plate 406 to rotate upward, so that the protrusion of the fixed rod 402 moves upward over the rotating plate 406. At this time, the rotating plate 406 rotates downward and resets under the action of gravity. In this way, during the downward stirring process, the effect of automatically adding a quantitative diluent is achieved, without the need for manual control of the addition amount of the diluent, and when resetting upward after the stirring is completed, it can be ensured that no more diluent is added.

[0046] Example 4: On the basis of Example 3, as Figure 11 shown, it further includes a magnetic ring 501, and the magnetic ring 501 is fixedly connected to the bottom of the first fixing frame 106.

[0047] If the second magnet 110 breaks free from the magnetic attraction of the first magnet 109 and drops downward due to external force factors, the magnetic ring 501 can magnetically attract the second magnet 110 a second time, so that the main stirrer 108 and the auxiliary stirrer 206 are suspended at the magnetic ring 501, avoiding the main stirrer 108 and the auxiliary stirrer 206 from falling to the bottom of the mixing cylinder 104. If the main stirrer 108 and the auxiliary stirrer 206 still fall to the bottom of the cylinder, when the magnetic ring 501 descends to the bottom of the cylinder, the main stirrer 108 and the auxiliary stirrer 206 can still be lifted upward by the magnetic attraction between the magnetic ring 501 and the second magnet 110.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
