Description

Technical Field

[0001] The present invention relates to the technical field of pig breeding, and particularly relates to an auxiliary device for batch thawing of pig frozen semen straws. Background Art

[0002] With the rapid development of the preservation technology of pig frozen semen (abbreviated as "frozen semen"), the artificial insemination effect of pig frozen semen has been comparable to that of semen preserved at room temperature (the evaluation indicators are the average conception rate and litter size). Pig breeding enterprises have fully realized the deficiencies of semen preserved at room temperature restricted by time and space and the importance of biosecurity. As a result, pig frozen semen, following cattle, has also started to rapidly enter the process of commercial production and popular application. There are already several pig breeding enterprises in China relying on their own boar stations for the standardized production and sales of pig frozen semen. Pig frozen semen, which has the advantages of being not restricted by time and space and having high biosecurity, has begun to be accepted and used by the majority of pig-raising customers.

[0003] Currently, the dosage form of pig frozen semen products is mainly straws (0.5 mL), and usually 4 - 6 frozen semen straws are required for one insemination. When thawing, generally, ordinary medical forceps are used to clamp a number of frozen semen straws (the number varies from person to person) and quickly transfer them from liquid nitrogen to a water bath (for example, the water temperature is 50 degrees). After a certain time in the water bath, the straws need to be quickly taken out. It is rather difficult to use traditional medical forceps to clamp multiple straws, and improper operation may cause loss of straws or a decline in the thawing effect. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary device for batch thawing of pig frozen semen straws to solve the above problems.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An auxiliary device for batch thawing of pig frozen semen straws of the present invention includes side plates and a bracket grid hinged to the bottom of the side plates. The bracket grid is in a saw-tooth shape. An adjusting component for controlling the rotation of the bracket grid is connected to the outer side wall of the side plates. A number of groups of semi-cylindrical lower card slots arranged side by side are formed on the top surface of the bracket grid. A cross plate is provided above the bracket grid, and one end of the cross plate is fixed to the inner wall of the side plates. A lower pressing plate is arranged between the cross plate and the bracket grid. Two cross pressing bars are connected to both side ends of the lower pressing plate. The end of one side of the cross pressing bar is slidably connected to the inner wall of the side plates. The top of the lower pressing plate is connected to the cross plate through a lifting component. Semi-cylindrical upper card slots corresponding to the lower card slots are formed on the bottom surfaces of the lower pressing plate and the cross pressing bars. A force application component is arranged in the upper card slots.

[0007] Further, the adjusting assembly includes a limiting member connected to the outer wall of the side plate and an extension plate connected to the side wall of the bracket grid bar. A vertically arranged strip-shaped hole is formed in the limiting member, and an adjusting rod is slidably connected in the strip-shaped hole. The bottom of the adjusting rod is placed in a groove formed in the extension plate. First sliding grooves are formed on both side walls of the groove. A sliding rod is connected to the side wall at the bottom of the adjusting rod, and the other end of the sliding rod is slidably connected in the first sliding groove. The rod body of the adjusting rod is clamped on the limiting member through a clamping assembly.

[0008] Further, a handle is connected to the top of the adjusting rod.

[0009] Further, the clamping assembly includes a micro pressing self-locking buckle provided on the rod wall of the adjusting rod and the top of the limiting member.

[0010] Further, the lifting assembly includes a threaded rod connected to the top surface of the lower pressing plate through a bearing. The top of the threaded rod threadedly penetrates through a threaded hole formed in the cross plate and is connected to a hand wheel. A first spring is sleeved on the rod body of the threaded rod between the cross plate and the lower pressing plate, and both ends of the first spring are respectively connected to the top surface of the lower pressing plate and the bottom surface of the cross plate.

[0011] Further, two symmetrically arranged second sliding grooves are formed on the inner side wall of the side plate. A guiding rod is installed in the second sliding groove, and a slider is slidably connected to the guiding rod. The slider is connected to the end of a cross pressing strip on one side of the lower pressing plate.

[0012] Further, the force applying assembly includes an arc-shaped pressing plate arranged in the upper clamping groove. The top surface of the arc-shaped pressing plate is connected to the top surface of the upper clamping groove through a plurality of second springs.

[0013] Further, a handle is connected to the top surface of the cross plate.

[0014] Further, the materials of the side plate and the bracket grid bar are both polytetrafluoroethylene or polyimide.

[0015] Further, a first liquid dropping hole is formed on the bottom surface of the lower clamping groove on the bracket grid bar. A slope frame is connected to one end of the two bracket grid bars away from the side plate.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0017] The present invention has a simple structure, is convenient to operate, and has a low cost. It can firmly clamp multiple frozen fine tubes at one time, quickly move them from liquid nitrogen to a water bath, and then quickly move them out to the air after a certain time in the water bath, and maintain the spacing between the frozen fine tubes, reducing the influence of liquid nitrogen on the water bath temperature.

Specific embodiments

[0026] As Figures 1-6 shown, a batch thawing auxiliary device for porcine frozen seminiferous tubules includes a side plate 1 and a bracket grid 2 hinged to the bottom of the side plate 1. The bracket grid 2 is saw-toothed, and the materials of the side plate 1 and the bracket grid 2 are both polytetrafluoroethylene or polyimide. One end of the two bracket grids 2 away from the side plate 1 is connected with an inclined plane frame 26, which is convenient for the frozen seminiferous tubules to move onto the bracket grid 2.

[0027] An adjustment component for controlling the rotation of the bracket grid bars 2 is connected to the outer side wall of the side plate 1. The adjustment component includes a limiting member 7 connected to the outer wall of the side plate 1 and an extension plate 8 connected to the side wall of the bracket grid bar 2. A vertically arranged strip-shaped hole is formed in the limiting member 7, and an adjustment rod 9 is slidably connected in the strip-shaped hole. The top of the adjustment rod 9 is connected with a grip 13, which is convenient for pressing down or pulling up the adjustment rod 9. The bottom of the adjustment rod 9 is placed in a groove 10 formed in the extension plate 8. First sliding grooves 11 are formed on both side walls of the groove 10. A sliding rod 12 is connected to the side wall at the bottom of the adjustment rod 9, and the other end of the sliding rod 12 is slidably connected in the first sliding groove 11. By pressing down or pulling up the grip 13, the adjustment rod 9 is driven to rise or fall, thereby driving the bracket grid bar 2 to rotate, so that it can be arranged vertically or horizontally.

[0028] The rod body of the adjustment rod 9 is clamped on the limiting member 7 through a clamping component. The clamping component includes a micro press self-locking buckle 14 arranged on the rod wall of the adjustment rod 9 and the top of the limiting member 7. The position of the adjustment rod 9 is limited by the micro press self-locking buckle 14. The micro press self-locking buckle 14 is a prior art, and its specific structure will not be described in detail here. When the micro press self-locking buckle 14 on the adjustment rod 9 is locked, the bracket grid bar 2 is exactly in a horizontal state at this time.

[0029] A number of groups of semi-cylindrical lower clamping grooves 3 arranged side by side are formed on the top surface of the bracket grid bar 2. The diameter of the lower clamping grooves 3 is larger than the diameter of the frozen fine tube. First liquid dropping holes 24 are formed on the bottom surface of the lower clamping grooves 3 on the bracket grid bar 2. When the frozen fine tube falls on the lower clamping grooves 3, the liquid nitrogen remaining in the lower clamping grooves 3 or on the frozen fine tube can flow downward along the first liquid dropping holes 24, preventing the liquid nitrogen from remaining in the lower clamping grooves 3.

[0030] A cross plate 4 is arranged above the bracket grid bar 2. A handle 23 is connected to the top surface of the cross plate 4. One end of the cross plate 4 is fixed to the inner wall of the side plate 1. A lower pressing plate 5 is arranged between the cross plate 4 and the bracket grid bar 2. Two cross pressing strips 25 are connected to both side ends of the lower pressing plate 5. The end of one side of the cross pressing strip 25 is slidably connected to the inner wall of the side plate 1. Two symmetrically arranged second sliding grooves 18 are formed on the inner side wall of the side plate 1. A guide rod 19 is installed in the second sliding grooves 18. A slider 20 is slidably connected to the guide rod 19. The slider 20 is connected to the end of the cross pressing strip 25 on one side of the lower pressing plate 5.

[0031] The top of the lower pressing plate 5 is connected to the cross plate 4 through a lifting assembly. The lifting assembly includes a threaded rod 15 connected to the top surface of the lower pressing plate 5 through a bearing. The top of the threaded rod 15 threadedly penetrates through a threaded hole formed in the cross plate 4 and is connected to a hand wheel 16. A first spring 17 is sleeved on the rod body of the threaded rod 15 between the cross plate 4 and the lower pressing plate 5. Two ends of the first spring 17 are respectively connected to the top surface of the lower pressing plate 5 and the bottom surface of the cross plate 4.

[0032] Semicylindrical upper card slots 6 corresponding to the lower card slots 3 are formed in the bottom surfaces of the lower pressing plate 5 and the cross pressing strip 25. A force applying assembly is arranged in the upper card slots 6. The force applying assembly includes an arc-shaped pressing plate 21 arranged in the upper card slots 6. The lowest horizontal height of the arc-shaped pressing plate 21 is lower than the lowest horizontal height of the upper card slots 6. The top surface of the arc-shaped pressing plate 21 is connected to the top surface of the upper card slots 6 through a plurality of second springs 22.

[0033] The operation process of the present invention is as follows:

[0034] During use, hold the handle 23, place the whole device above liquid nitrogen, then rotate the hand wheel 16 to make the threaded rod 15 drive the lower pressing plate 5 to rise, and at the same time drive the cross pressing strip 25 to rise. The bracket grid bars 2 are vertically arranged. Then place the bracket grid bars 2 against the inner wall of the liquid nitrogen box for placing frozen fine tubes and lower them until the bottom of the bracket grid bars 2 touches the frozen fine tubes at the edge. Then hold the grip 13 and press down the adjusting rod 9 to make the sliding rod 12 connected to the bottom of the adjusting rod 9 slide in the first sliding groove 11, driving the bracket grid bars 2 to rotate until the adjusting rod 9 is locked in position by the micro pressing self-locking buckle 14. At this time, the bracket grid bars 2 just keep horizontal. At this time, the cross plate 4 is placed above the liquid nitrogen, and some frozen fine tubes fall into the lower card slots 3. Then hold the handle 23 and push the whole device until all the lower card slots 3 are filled with frozen fine tubes. Then rotate the hand wheel 16 in the reverse direction to make the threaded rod 15 drive the lower pressing plate 5 to descend until the lower pressing plate 5 presses on the bracket grid bars 2. At this time, the cross pressing strip 25 will also press on the bracket grid bars 2. The inner wall of the arc-shaped pressing plate 21 presses on the frozen fine tubes, and the second spring 22 is compressed. The frozen fine tubes are firmly fixed in the lower card slots 3 through the arc-shaped pressing plate 21. Then take the device out of the box and quickly move it to a water bath (at a specific temperature). At the same time, press the timer. When the time shown on the timer reaches, quickly take the device out of the water bath, remove the fine tubes, wipe them clean with a tissue, move the thawed sperm to the thawing solution and mix well.
