Description

Technical Field

[0001] The invention relates to the technical field of semen dilution, in particular to a device for diluting fresh semen of a boar. Background Art

[0002] In the process of pig breeding, breeding of boars is a very important process. The number of sperm contained in the semen ejaculated by a boar at one time is far more than the number required for fertilization of a sow. In the process of artificial insemination of pigs, the semen can be diluted several times with a semen diluent. The diluted semen not only increases the volume, but also allows the semen to be preserved for a short or even long term use, so as to inseminate more sows, thereby improving the breeding efficiency of boars and greatly improving the reproduction rate of excellent boars.

[0003] In the existing boar semen dilution process, the prepared diluent is placed in a dilution jar or beaker, and then an appropriate amount of semen is manually poured into the diluent, and then stirred with a glass rod. This operation is not only inefficient, but also difficult to control the amount of semen poured by manual operation. It is easy to pour too much semen during pouring, so that the semen does not meet the dilution requirement. Moreover, manual stirring cannot be done vigorously, otherwise it will damage the sperm. It can only be stirred slowly, which is not only incomplete mixing but also time-consuming and labor-intensive. Moreover, the temperature difference between the semen and the diluent to be mixed cannot be too large, and the temperature difference between the diluent and the semen should not exceed 1°C, otherwise it will seriously affect the sperm motility after the semen is diluted. For this reason, we propose a boar fresh semen dilution device. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 and 2 As shown, a boar fresh semen dilution device comprises a box body 1, a dilution box 2 and a diluent box 3, a water bath chamber 4 is arranged in the box body 1, and the dilution box 2 and the dilution liquid box 3 are located in the water bath chamber 4; a heating plate 5 is arranged in the water bath chamber 4, and a temperature sensor 6 is arranged in the dilution box 2;

[0023] A circulation pipe 10 is provided on one side of the water bath chamber 4, the other end of the circulation pipe 10 is connected to the other side of the water bath chamber 4, and a circulation pump 9 is provided on the circulation pipe 10; temperature sensor 2 7 and temperature sensor 3 8 are respectively provided at the two pipe openings of the circulation pipe 10 in the water bath chamber 4, and the circulation pump 9 is used to drive the water in the water bath chamber 4 to circulate.

[0024] By adopting water bath heating, the temperature can be accurately controlled to avoid inactivation of boar fresh semen due to excessively high or low temperature. By setting a circulation pump 9, water on one side of the water bath chamber 4 can be pumped to the circulation pipe 10, and then injected into the water bath chamber 4 from the other side, so as to realize the circulation of water in the water bath chamber 4, avoid uneven water temperature, and then cause a temperature difference between the temperature and the semen temperature during the dilution process. The water bath chamber 4 heats the dilution tank 2 and the diluent tank 3 at the same time, ensuring that the temperature is uniform and stable during the dilution and stirring process, and at the same time ensuring that the diluent added to the semen is also kept at the same temperature as the semen in advance, avoiding a temperature difference during the addition of the diluent.

[0025] The dilution box 2 is provided with a filter mechanism 11, in which a detachable sterile gauze filter layer 23 and a flow valve 3 24 for detecting the amount of semen are arranged. The sterile gauze is used to filter the fresh semen, and the semen after the filtration is diluted.

[0026] The box body 1 is provided with a stirring motor 12, the output shaft of which is connected to a stirring rod 13 in the dilution box 2, and a stirring frame 14 is provided on the stirring rod 13. The stirring motor 12 drives the stirring rod 13 and the stirring frame 14 to rotate slowly to achieve dilution and stirring of semen.

[0027] A booster pump 15 is installed on the dilution tank 3, and the dilution tank 3 is connected to the dilution tank 2 through a dilution pipe 16. The booster pump 15 can increase the pressure in the dilution tank 3 to make the internal pressure greater than the external pressure and the dilution tank 2, so that the dilution enters the dilution tank 2 through the dilution pipe 16 under the action of pressure.

[0028] A flow valve 17 is provided on the diluent pipe 16, and the flow valve 17 can monitor the amount of diluent added, so as to control the amount of diluent added each time and better realize step-by-step dilution.

[0029] A liquid outlet pipe 18 is provided at the bottom of the dilution box 2, and the liquid outlet pipe 18 extends to the outside of the box body 1, and a flow valve 19 capable of detecting the single liquid output of the diluted semen is provided on the liquid outlet pipe 18. After the dilution is completed, the semen needs to be packaged, and the flow valve 19 can control the packaging amount each time.

[0030] A liquid level meter 20 is provided in the dilution box 2, and the liquid level meter 20 can detect the total amount of semen after dilution.

[0031] The box 1 is equipped with a controller 21, and a timer 22 is provided on the controller 21. The timer 22 is used to record the stirring time and the standing time. The controller 21 can control the operation of each electrical device and collect data from each sensor, and a PLC control system is specifically used. Due to the step-by-step dilution, it is necessary to stand for 5-10 minutes after dilution. The timer 22 can count, and continue to add diluent and stir after the timing ends. The stirring time, the amount of diluent added, and the standing time can all be set by the controller 21 to achieve fully automated step-by-step dilution.

[0032] The diluent box 3 is connected to the flushing head 26 through the flushing tube 25. The flushing head 26 is movably mounted on the box body 1 through the bracket 27 so that it can swing relative to the bracket 27 to adjust the flushing position. The flushing head 26 is aligned with the sterile gauze filter layer 23 of the filter mechanism 11. The flushing tube 25 is provided with a flow valve 28 for detecting the amount of pre-dilution added. The semen in the filtration process can be flushed by the flushing head 26 to avoid semen residue on the filter mechanism 11, and the filtration efficiency can also be improved. And the semen needs to be pre-diluted, that is, the volume ratio of semen and diluent is 1:1 for mixing. By directly using the diluent in the diluent box 3 heated by a water bath as the flushing liquid, the filtration efficiency can be improved while pre-dilution can be achieved.

[0033] The box body 1 is connected with a closed cover 29 by a hinge, and the closed cover 29 is used to cover the filter mechanism 11 and the flushing head 26. The bottom of the box body 1 is provided with a support leg 30. The closed cover 29 can play a protective and heat-insulating role, and the bracket 27 can ensure the stability of the box body 1.
