Description

Technical Field

[0001] The invention relates to the technical field of animal husbandry epidemic prevention, and in particular to a veterinary vaccine injection device. Background Art

[0002] Animal husbandry is an important part of the material exchange between humans and nature, and it is also an important part of agriculture. In modern animal husbandry, livestock vaccination has always been a rather thorny issue. At present, most people use manual injection methods to simply and roughly inject vaccines into livestock. This not only requires high labor intensity for personnel, but also causes the livestock to shake during vaccination, resulting in the vaccine sometimes not being fully injected. After searching, it was found that the Chinese invention patent with patent number CN 2022110616565 discloses an automatic veterinary vaccination device, including a livestock fixing mechanism, which drives a spiral rod through a motor to lift and lower a linkage rod, and the lifting of the linkage rod drives the sliders at both ends of the linkage rod to move, the slider drives the connecting rod, and the connecting rod drives the livestock fixing clamp to fix the livestock. This structure can fix livestock of different sizes.

[0003] However, the above example still cannot fix multiple livestock at one time. The livestock need to be captured one by one, and then fixed one by one through the livestock fixing mechanism before vaccination. This process still consumes too much manpower and time. In pastoral areas, a herder raises hundreds or even thousands of sheep. The above example obviously cannot meet the needs of vaccination of a large number of livestock in pastoral areas. Moreover, as long as the four feet of the livestock do not leave the ground during the fixation process, the livestock will jump around and move abnormally when they feel pain during the injection, which may easily cause harm to the veterinarian. In addition, the existing veterinary vaccination fixing device generally only clamps and fixes the animal from both sides. When the animal is clamped and fixed from both sides, the animal's trunk will be subjected to a large squeezing force, which may easily injure the animal's ribs. During the injection process, after each livestock is injected, a certain amount of liquid medicine needs to be re-inhaled into the syringe. This process requires manual operation by the veterinarian, which is relatively cumbersome and consumes a lot of physical strength of the veterinarian.

[0004] Based on the above, the present invention designs a veterinary vaccine injection device to solve the above problems. Summary of the invention

The second spring 48 is sleeved on the square guide rod 46. The first hydraulic cylinder 9 and the second hydraulic cylinder 38 are respectively connected to the external hydraulic station pipeline through a conduit.

[0029] A roller structure 49 is symmetrically fixed on the two workbenches 8, and the roller structure 49 includes an L-shaped mounting plate 50. A third hydraulic cylinder 51 is fixed to the top of the L-shaped mounting plate 50. The telescopic end of the third hydraulic cylinder 51 penetrates the L-shaped mounting plate 50 and is fixed with a universal wheel 52. The third hydraulic cylinder 51 is connected to the external hydraulic station pipeline through a conduit.

[0030] The distance between the two baffle structures 2 is 40-100 cm, and the distance between two adjacent rollers 5 is 10-30 cm.

[0031] Working principle: When the present invention is used, the telescopic end of the third hydraulic cylinder 51 is controlled to lift the device, so that the four universal wheels 52 can push the device to move to the work site, and then the four roller structures 49 are set to facilitate the convenient movement of the device. When vaccinating livestock, first open the entry door 3, and then drive the livestock (cow or sheep) into the space between the two baffle structures 2 through the entry door 3. The livestock entering between the two baffle structures 2 faces the exit door 4 and the tail faces the entry door 3. Since the spacing between the two baffle structures 2 is 40-100cm, the spacing is relatively narrow, so the livestock can be restricted from turning around and running back and forth between the two baffle structures 2 (the spacing between the two baffle structures 2 is 40-100cm. For smaller volumes, such as when vaccinating sheep, the present device with a smaller spacing between the two baffle structures 2 can be selected, so that the sheep can be restricted from turning around and running back and forth between the two baffle structures 2). For animals with a large volume, such as cattle, when being vaccinated, the device with a larger spacing between the two baffle structures 2 can be selected, so that the cattle can be restricted from turning around and running around between the two baffle structures 2. Therefore, according to the size of the livestock, the device with an appropriate spacing between the two baffle structures 2 can be selected to ensure that the livestock can enter between the two baffle structures 2 while ensuring that the spacing between the two baffle structures 2 can restrict the livestock from turning around at will. When an appropriate amount of livestock enters between the two baffle structures 2, the entry door 3 is closed, and then the telescopic ends of the two first hydraulic cylinders 9 of the two roller lifting structures 7 are controlled to rise synchronously, so that the multiple rollers 5 rise slowly and synchronously, and the multiple rollers 5 rise synchronously. During the rising process of the drum 5, due to the free rolling characteristics of the drum 5, the feet of the livestock cannot be fixed on the drum 5, and the four feet of the livestock slide down from between two adjacent drums 5. The distance between two adjacent drums 5 is 10-30cm, and the distance between two adjacent drums 5 is enough to accommodate the legs and feet of the livestock, ensuring that the legs and feet of the livestock can fall between two adjacent drums 5. In this way, during the rising process of multiple drums 5, the livestock can be stably lifted from the abdomen, the bottom of the chest cavity and the bottom of the neck of the livestock. At this time, the four feet of the livestock are suspended off the ground, and they cannot jump with the help of the four feet when injecting the vaccine. At this time, the telescopic end of the second hydraulic cylinder 38 is controlled to descend, so that the multiple n-shaped plates 41 slowly descend, and the multiple n-shaped plates When the roller 41 descends, the strap 43 between the two guide rollers 42 is tightened and pressed down by the second spring 48, and the livestock lifted up by the roller 5 is firmly fixed on the roller 5, which effectively prevents the livestock from twisting violently when the vaccine is injected. Then, through the arrangement of the roller 5, the roller lifting structure 7 and the pressing and fixing structure 36, multiple livestock entering between the two baffle structures 2 can be lifted and fixed at the same time before the vaccine is injected. When the livestock is vaccinated, the vaccine liquid is first poured into the medicine barrel 22, and then the telescopic end of the electric telescopic rod 28 is controlled to retract. When the telescopic end of the electric telescopic rod 28 is retracted, the piston 2 is synchronously driven to move toward the first cover plate 26.In this way, the piston 2 sucks the liquid medicine in the medicine barrel 22 into the piston cylinder 25 through the first connecting tube 23, the first connecting hose 32 and the second connecting tube 30 in turn. In this process, due to the one-way valve arranged in the third connecting tube 31, the outside air will not be sucked into the piston cylinder 25 through the needle 34. After the piston cylinder 25 sucks in an appropriate amount of liquid medicine, the veterinarian picks up the needle 34 hanging on the Y-shaped hanger 35, inserts the needle into the injection site of the livestock through the injection window 19, and then controls the telescopic end of the electric telescopic rod 28 to slowly extend, and injects the liquid medicine in the piston cylinder 25 into the livestock through the third connecting tube 31, the second connecting hose 33 and the needle 34 in turn, thereby completing the work of vaccinating the livestock. After all the livestock between the two baffle structures 2 have been vaccinated, the telescopic end of the first hydraulic cylinder 9 is controlled to retract and the roller 5 is lowered to its original position, so that the livestock can be placed back on the bottom plate 1. At the same time, the telescopic end of the second hydraulic cylinder 38 is controlled to retract and the n-shaped plate 41 is raised to its original position. At this time, the exit door 4 is opened to release the vaccinated livestock. When the livestock lifted by the roller 5 is put down, when the livestock's foot joint is stuck by the roller 5, the roller 5 will not continue to descend. The roller 5 stays in place through the sliding cylinder 14 to prevent the roller 5 from crushing the livestock's foot joint. When the livestock's foot is no longer stuck, the roller 5 automatically falls back to its original position under the action of the first spring 18.
