Description

Technical Field

[0001] The utility model relates to the technical field of livestock breeding detection equipment, in particular to a semen quality detection device for prolific mutton sheep breeding rams. Background Art

[0002] In the large-scale prolific mutton sheep breeding industry, the semen quality of breeding rams is a core key factor that determines the breeding success rate, offspring survival rate and population genetic improvement efficiency, and is directly related to the core economic benefits of breeding enterprises and the industrial sustainable development capacity. Indicators such as sperm motility, density and morphological integrity of high-quality semen are not only the premise for the successful implementation of artificial insemination technology, but also have a decisive influence on genetic traits such as growth performance and disease resistance of the offspring mutton sheep. The common detection method used in existing grassroots sheep farms or breeding sheep stations adopts the combination of traditional slides, cover slips and microscopes, in which the semen sample is mixed with the staining solution on the slide, the cover slip is placed thereon, and then the mixture is observed under a microscope. Since the lens of the microscope and the light source at the bottom are fixedly arranged, the slide needs to be manually and frequently moved to complete the detection of the entire area of the sample. Moreover, the semen sample has high requirements for temperature stability, the temperature of the sample will drop rapidly after it is dropped on the slide at room temperature, and the temperature fluctuation will be further changed during the subsequent frequent manual movement of the slide, resulting in distortion of key indicators such as sperm activity and morphology, and ultimately affecting the accuracy and repeatability of detection results.

[0023] Please refer to Figures 1 to 6, the present utility model provides a technical solution: a semen quality detection device for prolific mutton sheep breeding rams, comprising a base 1, a detection box body 2 is fixedly connected above the base 1, a placement notch 3 is formed through the upper side of the top plate of the detection box body 2 in a downward penetrating manner, an adjusting frame 4 is arranged at the rear side of the detection box body 2, a displacement assembly 5 is arranged between the adjusting frame 4 and the detection box body 2, the adjusting frame 4 is arranged in a "C" shape, a lens mechanism 6 is arranged on one side of the upper transverse plate of the adjusting frame 4 and above the placement notch 3, a light source mechanism 7 is fixedly installed on one side of the lower transverse plate of the adjusting frame 4 and inside the detection box body 2, the lens mechanism 6 corresponds to the light source mechanism 7, a transparent heating plate 8 is fixedly installed on the lower side of the top plate of the detection box body 2 and below the placement notch 3, and a sample slide 9 located in the placement notch 3 is placed above the transparent heating plate 8.

[0024] In this embodiment, a cover plate 10 is arranged between the top plate of the detection box body 2 and the upper transverse plate of the adjusting frame 4, a through groove 12 corresponding to the lens mechanism 6 is formed through the middle part of the cover plate 10, a vertical block 11 is fixedly connected to the upper side of the cover plate 10, a connecting groove 13 is formed through the upper side of the upper transverse plate of the adjusting frame 4 in a downward penetrating manner, the vertical block 11 is slidably fitted in the connecting groove 13, a fixing bolt 14 with one end penetrating into the connecting groove 13 is threadedly fitted on one side of the upper transverse plate of the adjusting frame 4, a fixing groove 15 matched with the fixing bolt 14 is formed on one side below the vertical block 11, and the cover plate 10 is located above the placement notch 3 to cover it.

[0025] Specifically, the semen sample mixed with the staining solution is dropped onto the sample slide 9, after the cover slip is covered, the sample slide 9 is placed above the transparent heating plate 8 through the placement notch 3 on the top plate of the detection box body 2; the transparent heating plate 8 works continuously to provide a constant suitable temperature of 37-38°C for the sample slide 9, so as to avoid temperature fluctuation of the sample caused by contact with a carrier at room temperature or environmental temperature change, the cover plate 10 is covered above the placement notch 3 through the sliding fit of the vertical block 11 and the connecting groove 13, which reduces the influence of the external environment on the sample temperature, the lens mechanism 6 observes the sample in the constant temperature environment below through the through groove 12 of the cover plate 10, and the light source mechanism 7 provides stable illumination to ensure detection clarity.

[0026] In this embodiment, the displacement assembly 5 includes a first screw 501 rotatably fitted between the two side plates of the detection box 2 and extending to the outside at one end. The detection box 2 has a connecting frame 502 inside that is threadedly fitted to the first screw 501 and located below the horizontal plate of the adjusting frame 4. The rear side plate of the detection box 2 has a through groove 16 that movably engages with the horizontal plate below the adjusting frame 4. The horizontal plate below the adjusting frame 4 is slidably fitted between the two side plates of the connecting frame 502. One end of the plate is provided with a threaded groove 503, and the inner wall of the threaded groove 503 is threaded with a second screw 504. The front side plate of the detection box 2 is provided with a strip-shaped through groove 505. The inner wall of the strip-shaped through groove 505 is rotatably and slidably fitted with a connecting post 506. Both ends of the connecting post 506 are fixedly connected to limiting plates 507 located on the front and rear sides of the strip-shaped through groove 505. One end of the second screw 504 is fixedly connected to one side of the limiting plate 507 and is located on the same central axis as the connecting post 506.

[0027] Specifically, the synchronous displacement of the lens mechanism 6 and the light source mechanism 7 is achieved through the displacement component 5, without the need to manually move the sample slide 9. Rotating the first screw 501 drives the threaded connecting frame 502 to move laterally along the detection box 2, which in turn drives the adjusting frame 4, which is slidably engaged with the connecting frame 502, to move laterally synchronously, thereby achieving the lateral position adjustment of the lens mechanism 6 and the light source mechanism 7. Rotating the second screw 504, using the thread transmission of the threaded groove 503, pushes the adjusting frame 4 to slide longitudinally along the connecting frame 502. At the same time, the connecting column 506 slides synchronously along the strip through groove 505 and is limited, thereby achieving the longitudinal position adjustment of the lens mechanism 6 and the light source mechanism 7.

[0028] Before using the device, preheat the transparent heating plate 8 to a suitable temperature of 37-38℃. After the temperature stabilizes, mix the semen sample and staining solution evenly in proportion, drop the mixture onto the surface of the sample slide 9, and cover it with a coverslip. Place the sample slide 9, carrying the sample, smoothly above the transparent heating plate 8 through the placement slot 3 on the top plate of the detection box 2. Then, push the cover plate 10 so that it slides through the connecting slot 13 of the horizontal plate above the adjustment frame 4 via the upright block 11, covering the placement slot 3 to reduce the interference of the external environment on the sample temperature. During detection, activate the light source mechanism 7 to provide stable illumination, and observe the sample initially through the lens mechanism 6. If it is necessary to observe different areas of the sample, adjust the detection angle through the displacement component 5: rotate the first screw 501 to drive the threaded connecting frame 502 along the detection box 2. The lateral movement causes the adjusting frame 4 and the lens mechanism 6 and light source mechanism 7 mounted on it to move laterally in sync. Rotating the second screw 504, the threaded transmission of the threaded groove 503 pushes the adjusting frame 4 to slide longitudinally along the connecting frame 502. At the same time, the connecting column 506 slides and is limited along the strip through groove 505, realizing the longitudinal position adjustment of the lens mechanism 6 and the light source mechanism 7. Through precise linkage adjustment in the lateral and longitudinal directions, clear observation of the entire sample area can be completed without moving the sample slide 9. After the test is completed, the cover plate 10 can be slid upward on the lateral plate above the adjusting frame 4 via the upright block 11. By tightening the fixing bolt 14 on one side of the adjusting frame 4, one end of it is embedded in the fixing groove 15 of the upright block 11, thus firmly fixing the cover plate 10. At this time, the cover plate 10 is located above the placement slot 3, which makes it easy to remove the moving sample slide 9.
