Description

Technical Field

[0001] The invention relates to the technical field of bovine embryo transplantation, in particular to an embryo transplantation device used for dairy cow embryo transplantation. Background Art

[0002] Embryo transplantation is actually a process in which the donor of the embryo and the recipient of the embryo work together to reproduce offspring. A freezing device is required during the transplantation of bovine embryos. Frozen embryos are the only mature method in the world to preserve fertility. This technology is to store bovine embryos obtained through test tube cultivation technology in test tubes, and store the test tubes in a liquid nitrogen environment at minus 196°C, so that the bovine embryos can be preserved for a long time, which is convenient for subsequent transplantation.

[0003] After searching, the Chinese patent application number CN202211092553.5 discloses a freezing device for bovine embryo transplantation that can monitor temperature, including a freezer, a door is arranged on the front side of the freezer, and a plurality of partitions are equidistantly arranged inside the freezer, and the plurality of partitions divide the interior of the freezer into a plurality of freezing chambers of the same size. However, due to the need to open the door on one side of the freezer when taking out the refrigerated frozen sperm test tubes, the multiple placement boxes stored inside the freezer will be exposed to the external environment after the door is opened, and the staff also need manual practical tools to take out the frozen sperm test tubes placed inside the freezer. Therefore, there is still a problem that the frozen sperm test tubes inside the multiple placement boxes are easily contaminated by the external environment when the door is opened, and the staff are easily frostbitten when manually taking out the frozen sperm test tubes. Summary of the invention

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] An elastic chuck is fixed to the telescopic end of the elastic telescopic rod, a plurality of aluminum alloy inner shells are fixed to the inner wall of the aluminum alloy shell, the top outer wall of the aluminum alloy inner shell penetrates the top outer wall of the aluminum alloy shell, an externally threaded sleeve is fixed to the top outer wall of the aluminum alloy inner shell, an internally threaded sleeve is fixed to the outer wall of the externally threaded sleeve through threads, a sealing cover is fixed to the outer wall of the internally threaded sleeve, a splint is fixed to the top outer wall of the sealing cover, the elastic chuck is plugged into the outer wall of the splint, a lifting rod is fixed to the bottom outer wall of the sealing cover, and a lifting tube is fixed to the outer wall of the lifting rod.

[0008] Preferably: the transmission mechanism includes a stepper motor, a rotating shaft, a limit rod and a limit groove, the rotating shaft is rotatably connected to the bottom outer wall of the mounting plate, the limit rod is fixed to the bottom outer wall of the mounting plate, the stepper motor is fixed to the outer wall of the limit rod, the output shaft of the stepper motor is connected to the outer wall of the rotating shaft through a coupling, the limit groove is arranged on the inner wall of the rotating sleeve, the limit rod is inserted into the inner wall of the limit groove, and the rotating shaft is transmission connected to the elastic telescopic rod through a transmission chain.

[0009] Furthermore: a control panel is fixed on the inner wall of the top of the transparent rotating cover, and the stepping motor is electrically connected to the control panel.

[0010] Further preferably, the inner walls on both sides of the elastic clamp are respectively fixed with second arc-shaped blocks, and the outer walls on both sides of the clamp are respectively fixed with first arc-shaped blocks.

[0011] As a preferred embodiment of the present invention: the aluminum alloy shell and the outer wall of the transparent rotating cover are respectively fixed with sealing rings, the sealing ring of the outer wall of the transparent rotating cover is fixed with a second metal positioning block, the sealing ring of the outer wall of the aluminum alloy shell is fixed with multiple first metal positioning blocks, the outer walls of the first metal positioning block and the second metal positioning block are respectively opened with positioning holes, the outer wall of the first metal positioning block is fixed with a magnet block, and the inner wall of the positioning hole is inserted with a positioning pin.

[0012] As a further preferred embodiment of the present invention: a handle is fixed to the outer wall of the mounting plate, a control button is arranged on the outer wall of the handle, and the control button is electrically connected to the control panel.

[0013] As a further solution of the present invention: a plurality of support plates are fixed to the outer wall of the bottom plate, and the support plates are fixed to the outer wall of the first metal positioning block.

[0014] On the basis of the above-mentioned scheme: a push handle is fixed on the outer wall of the bottom plate, a plurality of fixed pulleys are fixed on the outer wall at the bottom of the bottom plate, and a storage box is fixed on the outer wall at the top of the transparent rotating cover.

[0015] Based on the above solution, it is preferred that: a plurality of infrared counter-radiation sensors are fixed to the outer wall of the rotating sleeve and the clamping plate on the opposite side, and the infrared counter-radiation sensors are electrically connected to the control panel.

[0016] The beneficial effects of the present invention are:

[0017] 1. When the staff lifts the mounting plate, they can lift the sealing cover, the lifting rod and the lifting tube as a whole from the inner wall of the corresponding aluminum alloy liner through the inserted clamps and the elastic clamps to pull out the transparent rotating cover, which is convenient for the staff to clamp the frozen sperm test tube placed inside the lifting tube. The lifting tube can be conveniently taken out from the aluminum alloy liner without the staff directly contacting the low-temperature environment inside the aluminum alloy shell. At the same time, the transparent rotating cover and the aluminum alloy shell can continuously shield and seal the internal aluminum alloy liner to prevent the lifting tube in the remaining aluminum alloy liner from contacting the external environment. While facilitating the staff to take and place the frozen sperm test tube, the storage effect of the embryo transplantation device on frozen sperm is improved.

[0018] 2. After the elastic chuck is inserted into the outer wall of the splint, the second arc block located on the inner wall of the elastic chuck will be stuck in the lower part of the first arc block on the outer wall of the splint, so that the elastic chuck can stably lift the splint and pull the lifting tube out from the inside of the aluminum alloy inner liner. After the staff takes out the frozen sperm test tube stored in the lifting tube, the lifting tube can be inserted back into the aluminum alloy inner liner again. When the internal threaded sleeve of the outer wall of the sealing cover is against the outer wall of the external threaded sleeve, the staff can control the stepper motor to drive the elastic telescopic rod to rotate in the opposite direction for a corresponding number of circles, so that the internal threaded sleeve is re-fixed on the outer wall of the external threaded sleeve through threads, and the aluminum alloy inner liner is sealed by the internal threaded sleeve and the sealing cover.

[0019] 3. After the staff holds the mounting plate and rotates the transparent rotating cover to the corresponding angle, the second metal positioning block on the outer wall of the transparent rotating cover will be aligned with the corresponding first metal positioning block on the outer wall of the aluminum alloy shell. At this time, the magnet block on the outer wall of the first metal positioning block will be adsorbed on one side of the second metal positioning block through its own magnetic force, thereby temporarily limiting the transparent rotating cover after it is rotated to the corresponding position, making it convenient for the staff to limit the transparent rotating cover after it is rotated to the corresponding angle through the positioning pins later.

[0020] 4. When the staff inserts the lifting tube back into the aluminum alloy inner liner, the stepper motor will be controlled to drive the elastic telescopic rod to rotate in the opposite direction for the corresponding number of circles, thereby twisting the internal threaded sleeve through the elastic chuck, so that the internal threaded sleeve can be re-threaded on the external threaded sleeve. When the internal threaded sleeve is completely sleeved on the outer wall of the external threaded sleeve, the infrared radiation sensor located on the outer wall of the splint will also be emitted with the corresponding infrared radiation sensor on the outer wall of the rotating sleeve. At this time, the control panel will immediately control the stepper motor to turn off, avoiding the problem of excessive twisting of the splint by the elastic chuck causing damage to the transmission mechanism, thereby improving the stability and service life of the embryo transplantation device during operation.
