By adopting the technical scheme, the invention has the beneficial effects that:
because the rabbit milk automatic sampler comprises a sampling shell, wherein an auxiliary device, a holding device, a sampling container and a control system are arranged in the sampling shell, one of two sample tanks is used for placing an unused sampling container, the other one is used for placing the sampling container for collecting the rabbit milk sample, a worker controls a first speed reduction motor and a second speed reduction motor to start through a control panel on the outer side wall of the sampling shell, the first speed reduction motor and the second speed reduction motor can drive a sliding seat to move to the position of one sampling container, an electric push rod is started to withdraw a piston rod, so that a clamping claw clamps the corresponding sampling container inwards to clamp the sampling container, the sampling container is taken, then the first speed reduction motor and the second speed reduction motor drive the sampling container to move to the upper part of a holding roller, the rabbit milk sampling work is carried out on female rabbits in the holding roller, and the sampling container is driven to move to the other sample tank after the sampling is finished, the sampling container containing the rabbit milk sample is placed in the sample groove, so that the rabbit milk sampling work of the female rabbit is realized.
Compared with the problems that female rabbits are sampled one by workers in the existing manual sampling method, the sampling efficiency is low and the labor consumption of the workers is large, the automatic rabbit milk sampling method has the advantages that the automatic rabbit milk sampling is realized, the problems that the rabbit milk sampling efficiency is low and the labor consumption is large are solved, the time consumed for sampling the rabbit milk of a plurality of female rabbits is greatly shortened, the sampling efficiency of a sampler is improved, in the whole sampling process, the workers only need to operate through a control panel, the operation is very simple, and the working intensity of the workers is greatly reduced.
Because the retaining device comprises the fixed frame, the retaining roller and the retaining air bag, in the invention, a worker controls the female rabbit to enter the retaining roller from one end of the retaining roller, then the control panel controls the inflator pump to start, the inflator pump inflates the fixing air bag through the inflation tube to ensure that the fixing air bag expands rapidly, clamping and fixing the female rabbit in the fixing roller, starting a third speed reducing motor to drive the fixing roller to rotate, enabling a sampling opening on the side wall of the fixing roller to face upwards and then stopping, thereby realizing the fixation work of the rabbit, the inflation condition of the fixation air bag can be determined according to the size of the body of the rabbit, can be suitable for the fixation work of rabbits with different body sizes, has strong applicability, and the fixation air bag has elasticity, even if the rabbit struggles vigorously, the rabbit can not cause injury, and the safety of the use of the restraint device is improved.
Because the inner diameter of the retaining air bag is gradually reduced from the middle to the two ends, the inner diameter of the retaining air bag is large in the middle, the openings of the two ends are small, the small openings of the two ends can retain the neck and tail of a rabbit, and compared with the problem that the rabbit is easy to break away from the retaining air bag through a straight tube type air bag, the retaining air bag effectively improves the retaining effect on the rabbit.
Because the sampling container comprises the sample cup, the upper end cover, the rabbit milk suction nozzle, the lower end cover and the sealing cover, when the sampling container is clamped by the clamping claw on the auxiliary device, the air suction pipe at the bottom of the sampling container is communicated with the vacuum pump at the bottom of the sliding seat, the controller controls the vacuum pump to be started, the vacuum pump completely pumps out the air in the sample cup, negative pressure is formed in the sampling container, when the rabbit milk suction nozzle on the sampling container is abutted to the nipple of a female rabbit through the sampling opening on the retaining roller, the controller controls the second electromagnetic valve to be opened, the pressure in the sample cup is far smaller than the pressure at the rabbit milk suction nozzle to generate suction force in the rabbit milk suction nozzle, the effect that a baby rabbit sucks the nipple is simulated, the rabbit milk in the nipple of the female rabbit is sucked out into the rabbit milk suction nozzle, the fast sampling of the rabbit milk is realized, the sampling container in the invention adopts the mode of negative, the automatic sampling of the rabbit milk can be realized without manual operation, and the sample cup, the upper end cover and the lower end cover can be repeatedly used, so that the experiment cost is reduced.
Because the sealing seat is detachably provided with the sealing cover which is abutted against the end part of the sample cup, the lower end cover is internally provided with a metal part such as a return spring, so that the cleaning is inconvenient, but the sealing cover is directly contacted with the sample, and in order to ensure the quality of the rabbit milk sample, the sealing cover is required to be cleaned.
Because upper end cover and lower end cover are dismantled respectively and are installed in the both ends of sample cup, rabbit milk suction nozzle demountable installation can carry out the split with the sampling container on the appearance pipe of advancing of upper end cover to thoroughly washing and disinfection are conveniently carried out, avoid unclean sampling container to cause the pollution to rabbit milk sample, thereby have guaranteed the quality of rabbit milk sample in the sampling container.
According to the invention, the second sealing ring is used for sealing a gap between the outer wall of the sample cup and the sealing cover, and the first sealing ring is used for sealing the gap between the upper end cover and the outer wall of the sample cup, so that the sealing performance of the whole sample cup is ensured, the interior of the vacuumized sample cup is always kept in a vacuum state, the negative pressure sampling effect of the sampling container is ensured, and the leakage caused by the rabbit milk sample in the sample cup flowing out through the gap is also avoided.
Because the fixing frame is provided with the third proximity switch, and the side wall of the holding roller is also provided with the third induction block matched with the third proximity switch, in the invention, when the third proximity switch induces the third induction block, the third proximity switch can control the third speed reduction motor to stop, and the sampling opening on the side wall of the holding roller faces to the right upper side, so that the sampling container can finish sampling through the sampling opening.
Because the side wall of the sampling shell is provided with two taking and placing openings matched with the sample grooves, and each sample groove is internally and slidably provided with a fixing plate, when the sampling container needs to be taken out or placed into the sample groove, a worker only needs to draw out the fixing plate from the sample groove, and the use is very convenient.
