Description

Technical Field

[0001] The invention relates to the technical field of urine sampling, in particular to a urine sample sampler for animal husbandry and veterinary medicine. Background Art

[0002] In the process of animal husbandry, the health status of livestock is often sampled, and urine tests are generally used to test the health status of livestock. In order to ensure the accuracy of the sampled data, it is often necessary to collect urine from multiple livestock during the urine test. However, traditional urine sample samplers can only collect urine from one livestock at a time for storage, and cannot collect urine from multiple livestock, which makes the sampler inconvenient to use.

[0003] To avoid the above problems: In view of this: Announcement No. CN216754487U discloses a urine sample sampler for animal husbandry and veterinary medicine, including a base, an adjustment chamber is provided on the base, a rotating shaft is rotatably connected in the adjustment chamber, and an adjustment mechanism matched with the rotating shaft is arranged in the adjustment chamber, the upper end of the rotating shaft passes through the adjustment chamber and is fixedly connected to a shell, a plurality of liquid storage chambers are provided on the shell, and a piston plate is sealingly and slidably connected in the liquid storage chamber, and a fixing rod is fixedly connected to the piston plate. The utility model relates to the technical field of urine samplers, and through the provision of a plurality of liquid storage chambers, the device can classify and store the urine of a plurality of individual livestock, and at the same time, through the cooperation of the electromagnetic plate and the permanent magnet block, the electric push rod can control the synchronous sliding of each piston plate, so that each liquid storage chamber can simultaneously suck the urine of the corresponding individual livestock, which greatly facilitates the usability of the device.

This method is relatively limited and inconvenient for actual application. In order to avoid such problems, a urine sample sampler for livestock and veterinary medicine is proposed to optimize the existing problems and improve the portability of the sampler.

A plurality of support frames 101 are provided, and the plurality of support frames 101 are fixedly arranged on the surface of the multi-slot limit cover 801 in a surrounding and equidistant manner. Two extrusion baffles 102 are symmetrically installed on the top of the support frame 101.

[0028] Furthermore: in order to facilitate the automatic retention of a gap between the sampling tube 4 and the rubber piston plate 5, so as to facilitate the subsequent translation of the sampling bottle 904 through the gap stroke, a plurality of third sleeves 30 are fixedly connected equidistantly around the surface of the sampling tube 4, a third telescopic rod 31 is slidably connected inside the third sleeve 30, and a third return spring 32 is fixedly connected between the third telescopic rod 31 and the third sleeve 30, and a baffle 33 used in conjunction with the third telescopic rod 31 is fixedly connected to the surface of the pull rod 6.

[0029] The specific operation method is as follows: Step 1: Portable comfort debugging and multi-point mobile sampling: Portable and comfortable debugging: The operator adjusts the extension length of the push-pull rod 24 according to the height, so as to pull the device as a whole with effort through the push-pull rod 24. During the adjustment process, the thread locking cooperation of the first thread groove 25, the second thread groove 26 and the fastening bolt 27 at the current position is released, and then the length of the push-pull rod 24 is stretched or lowered. After the length of the push-pull rod 24 is adjusted to a suitable length, the second thread groove 26 and the second thread groove 26, which are at the same height at this moment, are thread-locked by the fastening bolt 27; Multi-point mobile sampling: The operator drags the device to move between multiple livestock urine troughs in sequence through the push-pull rod 24. After the device moves to the vicinity of the urine trough, the operator selects the sampling tube 4 close to the urine trough as the sample container, and then installs a disposable plastic transparent thin hose at the bottom of the sampling elbow 11 on the surface of the sampling tube 4, and inserts the bottom end of the hose into the urine, and then pulls the pull plate 7 to prompt the pull rod 6 to drive the rubber piston plate 5 to pump inside the current sampling tube 4. The first hole ring 13 and the first sealing plate 17 inside the sampling elbow 11 of the rubber piston plate 5 will be in a disconnected and closed state, and then the urine will be gradually pumped into the interior of the sampling tube 4. After the urine is extracted, the operator continues to drag the device to the next urine trough, and rotates the device to move other unloaded sampling tubes 4 closer to the urine trough; Step 2: Sample extraction height positioning and centralized control of material removal: Sample extraction height positioning: When the pull plate 7 is lifted upward to cause the rubber piston plate 5 to draw the sample tube 4, the pull plate 7 needs to be lifted into the groove at the bottom of the locking seat 805. During the process of the pull plate 7 entering the inner groove of the locking seat 805, the pull plate 7 will squeeze the locking block 808, causing the locking block 808 to finally elastically reset to the locking groove 810 inside the pull plate 7 to lock the position, thereby avoiding accidental squeezing and bumping of the pull plate 7, causing the sample tube 4 to discharge liquid accidentally. The subsequent pull plate 7 is operated as described above. Centralized control of material removal: After multiple sampling tubes 4 have completed sample extraction for multiple urine troughs, and the corresponding pull plates 7 are all locked with the locking seat 805, the operator squats down and manually twists the tail end of the threaded rod 802. The threaded rod 802 rotates, and the threaded sleeve 803 on its surface will carry several locking seats 805 to collectively descend through the limit plate 804. The descending of the locking seat 805 will carry the pull plate 7 to drive the pull rod 6 and the rubber piston plate 5 to apply pressure to the inside of the sampling tube 4, so that the second hole ring 18 and the second sealing plate 22 inside the sample discharge straight tube 12 form a passage, and discharge urine into the inside of the sample dispensing bottle 904 at the corresponding position; Step 3, container staggered expansion: during the process of the pull plate 7 driving the pull rod 6 and the rubber piston plate 5 to descend and apply pressure to the inside of the sampling tube 4, since there is a reserved space at the starting position between the sampling tube 4 and the rubber piston plate 5, the rubber piston plate 5 can discharge the urine sample into the interior of the sampling bottle 904 before reaching the bottom of the inner cavity of the sampling tube 4, and the corresponding limit plate 804 drives the pull plate 7, the pull rod 6 and the rubber piston plate 5 to descend through the locking seat 805, and the limit plate 804 also synchronously drives the vertical rod 905 to descend, and the vertical rod 905 drives the mounting frame 906 and The roller 907 descends, and when the rubber piston plate 5 has not reached the bottom of the inner cavity of the sampling tube 4 and the urine sample has been discharged, the roller 907 will be synchronously squeezed and contacted with the inclined rod 902, and the descending limit of the roller 907 will be accompanied by the rubber piston plate 5 descending to the bottom of the inner cavity of the sampling tube 4. The inclined rod 902 is forced to drive the moving block 901 and the mesh cover 903 to move horizontally, and the mesh cover 903 moves horizontally to carry the sample bottle 904 away from the bottom of the sample straight tube 12 and spread outward. Finally, the operator takes away several sample bottles 904 in turn for urine sample testing; Step 4, automatic release of lock: the locking seat 805 drives several pull plates 7 to descend, prompting the pull plate 7 to drive the rubber piston plate 5 through the pull rod 6 to discharge the sample inside the sampling tube 4. The first through groove 103 at the bottom of the locking seat 805 will slide vertically toward the extrusion baffle 102, prompting the extrusion baffle 102 to enter the trapezoidal groove 105 through the first through groove 103, and by squeezing the inclined inner wall of the trapezoidal groove 105, the locking block 808 and the locking slot 810 in the pull plate 7 are automatically released from the lock. When the corresponding limit plate 804 drives the locking seat 805 to reset, the locking block 808 will not be re-elastically locked with the locking slot 810 due to the obstruction of the extrusion baffle 102, resulting in the problem of insufficient lock release.
