Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sampling devices, and particularly relates to a sampling container for an automatic rabbit milk sampler. Background Art
[0002] Rabbits are multiparous animals. A female rabbit can give birth to at least 3 young rabbits at a time, and can even give birth to 7 - 8 young rabbits at a time. However, the milk of female rabbits not only secretes slowly and in small quantities, but also some female rabbits do not actively feed the young rabbits after giving birth. Therefore, most of the young rabbits after the female rabbits give birth need to be artificially fed. In order to fully simulate the lactation of female rabbits and make the nutritional components in the milk powder for feeding young rabbits as close as possible to those of rabbit milk, it is necessary to sample rabbit milk for research.
[0003] The main problems existing in the existing rabbit milk samplers are as follows: Currently, there is no dedicated rabbit milk sampling device. When most laboratories sample rabbit milk, there are mainly two methods, namely sampling with a milk extractor and manual milking sampling. Moreover, it is necessary for the staff to sample each female rabbit one by one. The sampling process is rather troublesome, consuming a large amount of energy of the staff, and the sampling efficiency is very low.
[0004] Therefore, a sampling container for an automatic rabbit milk sampler that can solve the above problems is needed. Summary of the Invention
[0005] The present invention provides a sampling container for an automatic rabbit milk sampler, which uses a negative pressure sampling method to achieve rabbit milk sampling. It can realize the automatic sampling of rabbit milk without manual operation. Moreover, the sample cup, the upper end cover, and the lower end cover in the present invention can be reused multiple times, thereby reducing the experimental cost.
[0006] The technical solution of the present invention is realized as follows:
[0007] The sampling container for the rabbit milk automatic sampler includes a sample cup, an upper end cover and a lower end cover which are threadedly installed at both ends of the sample cup. A sampling tube communicating with the inside of the sample cup is fixed in the middle of the upper end cover. A second solenoid valve is installed on the sampling tube. A rabbit milk suction nozzle is detachably installed at the end of the sampling tube. An air suction pipe adapted to the vacuum pump is installed at the bottom of the lower end cover. A sealing seat for sealing the sample cup is slidably installed inside the lower end cover. A second induction block adapted to the second proximity switch is also fixed at the bottom of the lower end cover. A sliding rod is fixed at the bottom of the sealing seat. A mounting seat with the sliding rod slidably installed inside is provided on the inner wall of the lower end cover. A return spring is jointly connected between the bottom of the sealing seat and the inner wall of the lower end cover. The return spring is sleeved outside the mounting seat and the sliding rod. A sealing cover is arranged inside the sealing seat. An annular rib is provided on the inner wall of the sealing seat. An annular groove adapted to the annular rib is provided on the outer wall of the sealing cover. The annular rib is inserted into the annular groove. A second sealing ring is fixed at the lower end of the sample cup and abuts against the inner wall of the sealing cover.
[0008] As a preferred technical solution, the upper end cover is threadedly installed at the upper end of the sample cup, and a first sealing ring is arranged between the inner wall of the upper end cover and the outer wall of the sample cup;
[0009] A connecting pipe is fixed at the bottom of the rabbit milk suction nozzle. The end of the connecting pipe away from the rabbit milk suction nozzle is threadedly installed on the sampling tube. The connecting pipe communicates the rabbit milk suction nozzle and the sampling tube;
[0010] An annular convex block is fixed at the lower end of the sample cup. The lower end cover is threadedly installed on the annular convex block.
[0011] As a preferred technical solution, two access openings adapted to the sample slots are provided on the side wall of the sampling housing. Mounting bosses are respectively fixed on both side walls of each sample slot. A fixing plate is jointly arranged on every two oppositely arranged mounting bosses. A plurality of fixing holes for fixing the sampling container are provided on each fixing plate. The sampling container with the rabbit milk suction nozzle facing down is arranged in each fixing hole.
[0012] Adopting the above technical solution, the beneficial effects of the present invention are:
[0013] Since the sampling container includes a sample cup, an upper end cap, a rabbit milk suction nozzle, a lower end cap, and a sealing cap, when the clamping claws on the auxiliary device in the present invention clamp the sampling container, the air suction pipe at the bottom of the sampling container is connected to the vacuum pump at the bottom of the sliding seat. The controller controls the vacuum pump to start, and the vacuum pump evacuates all the air inside the sample cup, creating a negative pressure inside the sampling container. When the rabbit milk suction nozzle on the sampling container is abutted against the nipple of the female rabbit through the sampling opening on the holding roller, the controller controls the second solenoid valve to open. The pressure inside the sample cup is much lower than the pressure at the rabbit milk suction nozzle, generating suction force inside the rabbit milk suction nozzle, simulating the effect of a baby rabbit sucking on a nipple, thereby sucking the rabbit milk inside the nipple of the female rabbit into the rabbit milk suction nozzle, achieving rapid sampling of rabbit milk. The sampling container in the present invention uses a negative pressure sampling method to achieve rabbit milk sampling, enabling automatic sampling of rabbit milk without manual operation. Moreover, the sample cup, upper end cap, and lower end cap in the present invention can all be reused multiple times, thereby reducing the experimental cost.
[0014] Since the sealing cap is detachably installed on the sealing seat and abuts against the end of the sample cup, and because there are metal components such as a return spring inside the lower end cap, it is not convenient to clean. However, the sealing cap is in direct contact with the sample. To ensure the quality of the rabbit milk sample, the sealing cap must be cleaned. The sealing cap in the present invention is detachably installed on the sealing seat. After using the present invention to complete one sampling, the staff can remove the sealing cap from the sealing seat for cleaning and disinfection or replacement, facilitating the next sampling and also ensuring the quality of the collected rabbit milk sample.
[0015] Since the upper end cap and the lower end cap are respectively detachably installed at both ends of the sample cup, and the rabbit milk suction nozzle is detachably installed on the sampling tube of the upper end cap, the sampling container can be disassembled to facilitate thorough cleaning and disinfection, avoiding contamination of the rabbit milk sample caused by an unclean sampling container, thereby ensuring the quality of the rabbit milk sample inside the sampling container.
[0016] Since a second sealing ring that abuts against the inner wall of the sealing cap is fixed at the lower end of the outer side wall of the sample cup, and a first sealing ring is provided between the inner wall of the upper end cap and the outer wall of the sample cup. In the present invention, the second sealing ring seals the gap between the outer wall of the sample cup and the sealing cap, and the first sealing ring seals the gap between the upper end cap and the outer wall of the sample cup, ensuring the tightness of the entire sample cup, so that the inside of the sample cup always remains in a vacuum state after being evacuated, to ensure the negative pressure sampling effect of the sampling container, and also avoiding leakage caused by the rabbit milk sample in the sample cup flowing out through the gap.
[0017] Since there are two pick-and-place openings adapted to the sample slots provided on the side wall of the sampling housing, and a fixing plate is slidably installed in each sample slot. In the present invention, when the staff needs to take out or put the sampling container into the sample slot, they can simply pull out the fixing plate from the sample slot, which is very convenient to use.

[0047] The third driving mechanism includes a third reduction motor 3012 fixed on the fixing frame 3001. The third reduction motor 3012 is connected to the controller 1002 and the third proximity switch 3010. A second driving gear 3013 is fixedly installed on the motor shaft of the third reduction motor 3012. A second driven gear 3014 meshing with the second driving gear 3013 is fixed on the outer side wall of the holding roller 3002.
[0048] The process of using the present invention for sampling rabbit milk is as follows:
[0049] In the first step, the staff controls the female rabbit to enter the holding roller 3002 from one end of the holding roller 3002. At this time, the inflation pump 3005 is controlled to start through the control panel 1001. The inflation pump 3005 inflates the holding airbag 3003 to clamp the female rabbit. After the inflation pump 3005 works for a period of time, the controller 1002 will control the inflation pump 3005 to close and control the third reduction motor 3012 to start. The third reduction motor 3012 drives the holding roller 3002 to rotate through power transmission. When the third proximity switch 3010 on the fixing frame 3001 senses the third induction block 3011, it will directly control the third reduction motor 3012 to stop working. At this time, the sampling opening 3008 on the side wall of the holding roller 3002 faces directly upward;
[0050] In the second step, the staff controls the first reduction motor 2016 to start through the control panel 1001. The first reduction motor 2016 drives the lifting seat 2003 to slide on the auxiliary frame 2001 through power transmission and makes the lifting seat 2003 move to a certain height. After the lifting seat 2003 moves to the predetermined height, the first reduction motor 2016 stops. At this time, the controller 1002 controls the second reduction motor 2022 to start. The second reduction motor 2022 drives the sliding seat 2004 to slide on the lifting seat 2003 and move towards one end of the sample tank 2002 containing the unused sampling container 400. After the second proximity switch 2008 at the bottom of the sliding seat 2004 senses the second induction block 4009, it controls the second reduction motor 2022 to stop. Then the controller 1002 controls the first reduction motor 2016 to start, driving the lifting seat 2003 and the sliding seat 2004 to descend, and making the two clamping claws 2005 insert downward into the sample tank 2002 and be located on both sides of the sampling container 400;
[0051] In the third step, at this time, the controller 1002 controls the first reduction motor 2016 to stop and the electric push rod 2006 to start. The piston rod of the electric push rod 2006 retracts, driving the first sliding block 2014 to slide upward in the second sliding cavity 2013. The first sliding block 2014 drives the clamping claws 2005 to also move upward. Under the blocking action of the inner walls of the corresponding second sliding cavities 2013, the two clamping claws 2005 rotate inward simultaneously to clamp the sampling container 400. Then, the controller 1002 controls the first reduction motor 2016 to start and drive the lifting seat 2003 to rise, and then controls the second reduction motor 2022 to start and drive the sliding seat 2004 to move in the direction of the holding roller 3002;
[0052] In the fourth step, when the clamping claws 2005 in the auxiliary device 200 clamp the sampling container 400, the air suction pipe 4007 at the bottom of the sampling container 400 is connected to the vacuum pump 2009 at the bottom of the sliding seat 2004. During the movement of the sliding seat 2004, the controller 1002 controls the vacuum pump 2009 to start. The vacuum pump 2009 generates suction inside the lower end cover 4003 through the air suction pipe 4007. Under the suction of the vacuum pump 2009, the sealing seat 4008 causes the sealing cover 4012 to separate from the bottom of the sample cup 4001, making the inside of the sample cup 4001 communicate with the inside of the lower end cover 4003. The air in the sample cup 4001 and the lower end cover 4003 is pumped out by the vacuum pump 2009 to form a vacuum space. After the controller 1002 controls the vacuum pump 2009 to stop working, the sealing seat 4008 drives the sealing cover 4012 to re-abut against the end of the sample cup 4001 under the elastic force of the return spring 4015 to seal the sample cup 4001, and a negative pressure is formed inside the sample cup 4001;
[0053] In the fifth step, when the first proximity switch 2007 on the sliding seat 2004 senses the first sensing block 3009 on the holding roller 3002, the first proximity switch 2007 controls the second reduction motor 2022 to stop and controls the first reduction motor 2016 to start. After the first reduction motor 2016 drives the lifting seat 2003 to descend a certain height, the controller 1002 controls the first reduction motor 2016 to stop. At this time, the rabbit milk suction nozzle 4006 on the sampling container 400 abuts against the nipple of the female rabbit through the sampling opening 3008. At the same time, the controller 1002 controls the second solenoid valve 4005 to open to connect the rabbit milk suction nozzle 4006 with the sample cup 4001. Under the negative pressure, the rabbit milk in the nipple of the female rabbit is sucked into the sample cup 4001 through the rabbit milk suction nozzle 4006;
[0054] In the sixth step, after the sampling is completed, the controller 1002 controls the second solenoid valve 4005 to close, and then controls the first reduction motor 2016 and the second reduction motor 2022 to drive the sampling container 400 to move to the corresponding sample slot 2002. When the sampling container 400 is inserted downward into the corresponding fixing hole 2027, the controller 1002 controls the piston rod of the electric push rod 2006 to extend, driving the clamping claw 2005 to move outward in the second sliding cavity 2013. After the clamping claw 2005 extends out of the sliding seat 2004, it rotates outward and opens under the elastic force of the torsion spring 2012, releasing the sampling container 400 and placing it in the sample slot 2002.
[0055] In the seventh step, the staff controls the third reduction motor 3012 to start through the control panel 1001, driving the holding drum 3002 back to its original position. Then, the controller 1002 controls the first solenoid valve 3006 to close, and the air in the holding airbag 3003 is discharged through the exhaust pipe 3007. The holding airbag 3003 retracts, and the rabbit can leave the holding drum 3002 from the other end of the holding drum 3002, completing the entire process of collecting rabbit milk from the female rabbit.
[0056] In summary, the automatic rabbit milk sampler proposed by the present invention can realize the automatic sampling of rabbit milk, solve the problems of low working efficiency and high energy consumption in rabbit milk sampling, greatly shorten the time of rabbit milk sampling, and reduce the work intensity of the staff. It has the characteristics of simple operation, high sampling efficiency, and high use safety.
[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
