Description

Technical Field

[0001] The invention relates to the technical field of livestock artificial breeding and fertilization equipment, and in particular to a multifunctional intelligent gun body for timed insemination of dairy cows and a use method thereof. Background Art

[0002] Artificial insemination technology is a method of injecting semen directly into the reproductive system of cattle, rather than through natural mating. This technology can improve the reproductive efficiency of cattle because it ensures that the semen reaches the uterus directly, thereby increasing the possibility of fertilization. The steps of this technology include: collecting the semen of the bull, checking its quality and activity, and then injecting the semen into the uterus of the cow at the appropriate time; currently, in the field of artificial insemination of cows, the commonly used semen capillaries are mainly spring-clip type, thread type and barrel expansion type.

[0003] After searching, the Chinese patent application number CN202411233149.4 discloses a sterile insemination gun for cattle, including a proximal end and a distal end, the proximal end of the sleeve is connected to the handle, and the distal end of the sleeve is provided with an end cap, and the end cap is provided with an endoscope hole and an illumination hole. However, the above technical solution requires that after the sleeve is aimed at the cow's uterine opening, the semen cap containing the frozen sperm tube is inserted into the insemination channel, so that the frozen sperm tube protruding from one side can be inserted into the cow's uterus for a certain distance, and then the cap is pushed The insemination gun needs to be pushed up and down on one side of the gun to squeeze the semen into the cow's uterus. After the insemination is completed, the capillary insemination gun needs to be pulled out, and the sleeve that limits the frozen sperm tube on the outer wall needs to be pulled out and replaced before the next insemination operation can be performed. Therefore, each insemination needs to be performed. After the sleeve is aimed at the cow's uterus, the capillary insemination gun needs to be inserted before the semen inside the frozen sperm tube can be injected into the uterus through the capillary insemination gun, which makes the insemination operation more complicated and leads to the problem of low efficiency of cow insemination. Summary of the invention

[0010] Further preferably, a control switch is arranged on the outer wall of the handle, a brush plate is fixed on the outer wall of the threaded rod, and the control switch is electrically connected to the stepping motor.

[0011] As a preferred embodiment of the present invention: a fixing frame is fixed to the outer wall of one side of the mounting block, a threaded rod passes through the outer wall of one side of the fixing frame, a group of guide plates are fixed to the outer wall of the fixing frame, a connecting block is fixed to the outer wall of the top of the guide plate, a second airbag is arranged on the outer wall of one side of the connecting block, a second L-shaped rod is fixed to the outer wall of one side of the fixing plate, a push plate is fixed to the outer wall of the second L-shaped rod, an exhaust valve is arranged on the outer wall of one side of the second airbag, and the exhaust valve passes through the outer wall of one side of the push plate.

[0012] As a further preferred embodiment of the present invention: a guide rail is fixed to the inner wall at the bottom of the installation cavity, a fixing plate is slidably connected to the outer wall of the guide rail, a guide rod is fixed to the inner wall on one side of the installation cavity, and an electric heating strip is arranged on the outer wall at the bottom of the guide rod.

[0013] As a further solution of the present invention: a first airbag is fixed to the inner wall of the installation cavity, and one end of the first airbag is connected to the exhaust valve through an air guide pipe.

[0015] On the basis of the above-mentioned scheme, it is preferred that: the inner walls on both sides of the installation cavity are slidably connected with support plates, a movable plate is fixed to the outer wall of one side of the support plate, a support frame is fixed to the outer wall of the bottom of the guide plate, a cylinder is fixed to the outer wall of the support frame, the output shaft of the cylinder is fixed to the outer wall of one side of the movable plate, the input end of the cylinder is connected to one end of the second airbag through an air guide tube, and one end of the first L-shaped rod is fixed to the outer wall of one side of the movable plate.

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

[0017] 1. When one end of the outer sleeve is aligned with the cow's uterine opening, the staff can start the pushing mechanism to push the fixed plate forward as a whole, thereby driving the roller to roll forward through the fixed plate, and the roller that continuously rolls forward continuously squeezes the frozen sperm tube from one end, thereby squeezing the semen stored in the frozen sperm tube and ejecting it. The semen ejected through the frozen sperm tube will pass through the sperm duct into the cow's uterus, and then the staff can complete the insemination by pulling out the outer sleeve. After that, it is only necessary to replace the frozen sperm tube and disinfect and clean the outer wall of the outer sleeve. There is no need to frequently pull out and insert the sperm tube insemination gun, and the insemination operation can be completed quickly, thereby improving the efficiency of scheduled insemination of cows.

[0018] 2. The second airbag can support and limit the frozen sperm tube inserted into the outer sleeve. When the fixed plate pushes the roller to roll forward, the second airbag will be squeezed by the push plate at the same time. After the second airbag is compressed, the internal gas will be ejected through the exhaust valve, so that the second airbag can continuously shorten its own length according to the roller rolling forward. While stably supporting the frozen sperm tube, it will not hinder the roller from squeezing the frozen sperm tube.

[0019] 3. When the second airbag is squeezed, the internal gas will be transported to the first airbag through the exhaust valve and the air guide tube for storage. After completing an insemination, the staff will first pull out the outer sleeve from the cow's vagina, then unscrew the sperm tube from one side of the internal threaded socket, pull out the flattened frozen sperm tube, and then press the control switch to control the stepper motor to rotate in the opposite direction, thereby driving the roller and the fixed plate to move backward and reset as a whole. When the fixed plate moves back, the second airbag can be stretched by the push plate while squeezing the first airbag on one side, so that the gas previously filled into the first airbag is filled back into the second airbag.

[0020] 4. When the roller squeezes the frozen sperm tube, the gas inside the second airbag enters the first airbag through the exhaust valve, and also enters the cylinder through the air supply pipeline, thereby pushing the movable plate forward through the output shaft of the cylinder, and pushing the first L-shaped rod forward through the movable plate. When the first L-shaped rod moves forward, it will pull the nozzle forward through the arc-shaped card plate inserted in the card slot on the outer wall. When the nozzle moves forward, it will stretch the telescopic bellows between the nozzle and the sperm discharge tube, so that the semen sprayed into the sperm discharge tube is sprayed into the uterus under the guidance of the telescopic bellows and the nozzle. At the same time, the nozzle moving forward can penetrate deeper into the cow's uterus, thereby improving the success rate of cow fertilization.

[0021] 5. The plug plate can be adsorbed on the inner wall of the slot by magnetic force, so as to support the nozzle on one side of the ejaculation tube as a whole, and prevent the nozzle from being displaced when semen is not injected. After the insemination is completed, the gas inside the cylinder will be sucked back into the second airbag again. At this time, the first L-shaped rod as a whole will also move back and reset under the drive of the cylinder, so that the protruding nozzle can be re-inserted into the side of the ejaculation tube through the arc-shaped clamping plate. Then the staff can easily unscrew the ejaculation tube from one end of the internal threaded socket through the nozzle at one end of the protruding outer sleeve, and replace the frozen semen tube.

[0035] The inner wall of the internal threaded socket 15 is connected to an external threaded tube 38 through threads, and a sperm discharge tube 42 is fixed to the outer wall of the external threaded tube 38;

[0036] A mounting block 8 is fixed to the inner wall of the mounting cavity 36 , a miniature camera 9 is arranged on the outer wall of the mounting block 8 , a handle 5 is fixed to the outer wall of the outer sleeve 1 , and a display panel 2 is fixed to the outer wall of the outer sleeve 1 .

[0037] The staff first inserts the thawed frozen sperm tube 25 into the internal threaded socket 15 at one end of the outer sleeve 1 until the end of the frozen sperm tube 25 with the sealing cotton is stuck between the roller 28 and the gap between the extrusion chamber 37. Then the staff sleeves the sperm discharge tube 42 on the inner wall of the internal threaded socket 15 through the thread to limit the end of the frozen sperm tube 25 protruding from the outer sleeve 1. Then the staff holds the handle 5 to insert the outer sleeve 1 as a whole into the cow's vagina. The micro camera 9 on one side of the mounting block 8 can take pictures of the inside of the cow's vagina, and the pictures are displayed on the display panel 2, which is convenient for the staff to align one end of the outer sleeve 1 with the cow's uterine opening. When one end of the outer sleeve 1 is aligned with the cow's uterine opening, the outer sleeve 1 is closed. After the cow's uterus is reached, the staff can start the pushing mechanism to push the fixed plate 18 to move forward as a whole, thereby driving the roller 28 to roll forward through the fixed plate 18, and the roller 28 that continuously rolls forward continuously squeezes the frozen sperm tube 25 from one end of the frozen sperm tube 25, thereby squeezing the semen stored in the frozen sperm tube 25 and ejecting it. The semen ejected through the frozen sperm tube 25 will pass through the sperm discharge duct 42 into the cow's uterus, and then the staff can complete the insemination by pulling out the outer sleeve 1. Then, it is only necessary to replace the frozen sperm tube 25 and disinfect and clean the outer wall of the outer sleeve 1 at the same time. There is no need to frequently pull out and insert the sperm tube insemination gun, and the insemination operation can be completed quickly, thereby improving the efficiency of regular insemination of dairy cows.

[0039] The outer wall of the handle 5 is provided with a control switch 6, and the control switch 6 is electrically connected to the stepper motor 4; after the staff holds the handle 5 to insert the outer sleeve 1 and move it to the side of the cow's uterine opening, the staff can press the control switch 6 on the side of the handle 5 by finger, thereby controlling the stepper motor 4 to drive the threaded rod 11 to rotate. When the threaded rod 11 rotates, it will drive the fixed plate 18 slidably connected to the inner wall of the outer sleeve 1 to move forward through the thread of the outer wall, thereby pushing the roller 28 to move forward as a whole through the fixed plate 18 to squeeze out the semen inside the frozen sperm tube 25.

[0040] like Figure 3-5As shown, a fixing frame 21 is fixed to the outer wall of one side of the mounting block 8, the threaded rod 11 penetrates the outer wall of one side of the fixing frame 21, a group of guide plates 23 are fixed to the outer wall of the fixing frame 21, a connecting block 22 is fixed to the outer wall of the top of the guide plate 23, a second air bag 24 is arranged on the outer wall of one side of the connecting block 22, a second L-shaped rod 19 is fixed to the outer wall of one side of the fixing plate 18, a push plate 26 is fixed to the outer wall of the second L-shaped rod 19, an exhaust valve 27 is arranged on the outer wall of one side of the second air bag 24, and the exhaust valve 27 penetrates one side of the push plate 26. On the side outer wall; the second airbag 24 can support and limit the frozen sperm tube 25 inserted into the outer sleeve 1. When the fixed plate 18 pushes the roller 28 to roll forward, the second airbag 24 will be squeezed by the push plate 26 at the same time. After the second airbag 24 is pressurized, the internal gas will be ejected through the exhaust valve 27, so that the second airbag 24 can continuously shorten its own length according to the roller 28 that continues to roll forward. While stably supporting the frozen sperm tube 25, it will not hinder the roller 28 from squeezing the frozen sperm tube 25.

[0041] like Figure 3-5 As shown, a guide rail 20 is fixed to the inner wall at the bottom of the installation cavity 36, and the fixed plate 18 is slidably connected to the outer wall of the guide rail 20. A guide rod 33 is fixed to the inner wall on one side of the installation cavity 36, and an electric heating strip 32 is provided on the outer wall at the bottom of the guide rod 33; the guide rail 20 can guide and limit the fixed plate 18 when it moves forward and backward, and the electric heating strip 32 on one side of the guide rod 33 can heat the outer sleeve 1 as a whole, thereby improving the comfort of the outer sleeve 1 when it is inserted into the cow's vagina and avoiding greater discomfort to the cow.

[0042] like Figure 3-5 As shown, a first airbag 17 is fixed to the inner wall of the installation cavity 36, and one end of the first airbag 17 is connected to the exhaust valve 27 through an air duct; when the second airbag 24 is squeezed, the internal gas will be transported to the first airbag 17 through the exhaust valve 27 and the air duct for storage. After completing an insemination, the staff first pulls out the outer sleeve 1 from the cow's vagina, then unscrews the sperm discharge tube 42 from one side of the internal threaded socket 15, pulls out the flattened frozen sperm tube 25, and then presses the control switch 6 to control the stepper motor 4 to rotate in the opposite direction, thereby driving the roller 28 and the fixed plate 18 to move backward and reset as a whole. When the fixed plate 18 moves back, the second airbag 24 can be stretched by the push plate 26, while the first airbag 17 on one side can be squeezed, so that the gas previously filled into the first airbag 17 is filled back into the second airbag 24.

[0043] like Figure 2-4As shown in Figures 6-8, a magnet ring 40 is fixed to the outer wall of the semen discharge tube 42, a plurality of slots 41 are opened on the outer wall of the magnet ring 40, a plug plate 39 is inserted into the inner wall of the slot 41, a nozzle 13 is fixed to the outer wall of the plug plate 39, a slot 43 is opened on one side of the outer wall of the plug plate 39, a first L-shaped rod 12 is slidably connected to the inner wall of the mounting block 8, an arc-shaped card plate 44 is fixed to the outer wall of the first L-shaped rod 12, the arc-shaped card plate 44 is inserted into the inner wall of the slot 43, a telescopic bellows 14 is connected between the semen discharge tube 42 and the nozzle 13, and the first L-shaped rod 12 passes through the outer wall of one side of the fixed frame 21;

[0044] The inner walls on both sides of the installation cavity 36 are slidably connected with support plates 30, a movable plate 31 is fixed to the outer wall of one side of the support plate 30, a support frame 35 is fixed to the outer wall of the bottom of the guide plate 23, a cylinder 34 is fixed to the outer wall of the support frame 35, the output shaft of the cylinder 34 is fixed to the outer wall of one side of the movable plate 31, the input end of the cylinder 34 is connected to one end of the second airbag 24 through the air guide tube, and one end of the first L-shaped rod 12 is fixed to the outer wall of one side of the movable plate 31; when the roller 28 squeezes the frozen fine tube 25, the gas inside the second airbag 24 enters the first airbag 17 through the exhaust valve 27, and also passes through The air delivery pipeline enters the cylinder 34, thereby pushing the movable plate 31 forward through the output shaft of the cylinder 34, and pushing the first L-shaped rod 12 forward through the movable plate 31. When the first L-shaped rod 12 moves forward, the arc-shaped clamping plate 44 inserted in the clamping groove 43 through the outer wall will pull the nozzle 13 forward. When the nozzle 13 moves forward, the telescopic bellows 14 between the nozzle 13 and the sperm discharge tube 42 will be stretched, so that the semen sprayed into the sperm discharge tube 42 is sprayed into the uterus under the guidance of the telescopic bellows 14 and the nozzle 13. At the same time, the nozzle 13 moving forward can penetrate deeper into the cow's uterus, thereby improving the success rate of cow fertilization;

[0045] The insert plate 39 can be adsorbed on the inner wall of the slot 41 by magnetic force, thereby supporting the nozzle 13 on one side of the semen discharge tube 42 as a whole, and preventing the nozzle 13 from being displaced as a whole when semen is not injected. After the insemination is completed, the gas inside the cylinder 34 will be sucked back into the second air bag 24 again. At this time, the first L-shaped rod 12 as a whole will also move back and reset under the drive of the cylinder 34, so that the protruding nozzle 13 can be reinserted into the side of the semen discharge tube 42 through the arc-shaped clamping plate 44. Subsequently, the staff can conveniently unscrew the semen discharge tube 42 from one end of the internal threaded socket 15 through the nozzle 13 at one end of the outer sleeve 1, and replace the frozen semen tube 25.

Then the staff sleeves the sperm discharge tube 42 on the inner wall of the internal threaded socket 15 through the thread to limit the end of the frozen sperm tube 25 protruding from the outer sleeve 1. Then the staff holds the handle 5 to insert the outer sleeve 1 as a whole into the cow's vagina. The micro camera 9 on one side of the mounting block 8 can take pictures of the situation inside the cow's vagina, and the pictures are displayed on the display panel 2, so that the staff can align one end of the outer sleeve 1 with the cow's uterine opening for convenience. When one end of the outer sleeve 1 is aligned with the cow's uterine opening, the staff can start the pushing mechanism to push the fixed plate 18 to move forward as a whole, thereby driving the roller 28 to roll forward through the fixed plate 18, and the roller 28 that continuously rolls forward continuously squeezes the frozen sperm tube 25 from one end of the frozen sperm tube 25, thereby squeezing and ejecting the semen stored in the frozen sperm tube 25, and the semen ejected through the frozen sperm tube 25 will pass through the sperm discharge duct 42 into the cow's uterus, and then the staff can complete the insemination by pulling out the outer sleeve 1, and then only need to replace the frozen sperm tube 25 and disinfect and clean the outer wall of the outer sleeve 1, without frequently pulling out and inserting the sperm tube insemination gun, and the insemination operation can be quickly completed.
