Description

Technical Field

[0001] This invention relates to the field of vaccination technology, and more particularly to a continuous vaccination device for biological inoculation. Background Technology

[0002] Bovine nodular dermatitis is an infectious disease caused by certain strains of goat pox virus or sheep pox virus. It is mainly transmitted through mosquito bites, causing nodules and ulcers on the surface of cattle. In severe cases, it can affect the health and productivity of cattle. To prevent bovine nodular dermatitis, freeze-dried live vaccines of goat pox or sheep pox can be used. These vaccines provide protection by injection into the inner layer of skin at the base of the tail. In current technology, when vaccinating cattle, the head of the cattle is first fixed in an iron frame. Usually, one person holds the vaccine while another person assists in fixing the tail (or a single person fixes the tail and injects the vaccine at the same time). Brucella can be transmitted through excrement, and the base of the tail is close to its excretory opening. If the vaccinated cattle carry Brucella, the Brucella on the tail may be transferred to the hands of the assistant (or the person administering the vaccine) when the tail is fixed. If not handled properly, the assistant (or the person administering the vaccine) may be infected with Brucella, thus affecting their health. Summary of the Invention

[0003] To overcome the drawback of existing methods where, if a cow carries Brucella bacteria, the bacteria on the cow's tail may contaminate the hands of the assistant (or the person administering the vaccine) when the tail is secured. If not handled properly, this could lead to Brucella infection and affect the health of the assistant (or the person administering the vaccine). Therefore, this invention provides a continuous vaccination device for biological inoculation that can be fixed in place.

Mirror-distributed telescopic rods are fixedly connected to the bearing plate. The fixed part of the telescopic rod is connected to the transfer shell by a pipe, and the telescopic end of the telescopic rod is fixedly connected to an adjacent first sliding frame.

[0006] Preferably, the fastening mechanism includes mirror-distributed second electric push rods, which are respectively fixed to adjacent side plates.

Fastening straps are fixed to opposite sides of the mirror-distributed second sliding frames, and the mirror-distributed fastening straps are located between the mirror-distributed side plates.

[0007] Preferably, the injection switching mechanism includes a third sliding frame, which is slidably connected to the rear baffle.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the use of terms such as "up," "down," "left," "right," "front," and "back" in this text is based solely on the accompanying drawings and is not intended to limit the specific scope of the invention.

[0028] In current techniques for vaccinating cattle, the cow's head is first fixed in a metal frame. Typically, one person holds the vaccine while another assists in fixing the cow's tail (or one person fixes the tail while simultaneously injecting the vaccine). Brucella can be transmitted through excrement, and the base of the cow's tail is close to its excretory opening. If the cow carrying Brucella is being vaccinated, the Brucella from the tail may transfer to the hands of the assistant (or the person administering the vaccine) while the tail is being fixed. If not handled properly, this can lead to Brucella infection in the assistant (or the person administering the vaccine), thus affecting their health.

[0029] Example 1: A continuous vaccination device for biological inoculation, please refer to... Figures 1-3The system includes a support plate 1 with inclined surfaces on both sides to assist the movement of the cattle being vaccinated. Two side plates 2, mirror-image distributed front to back, are fixed to the support plate 1 to restrict the cattle's range of motion. A top plate 3 is fixed to the support plate 1 via a mounting frame. The two side plates 2 are located between the support plate 1 and the top plate 3. A rear baffle 4 is slidably connected to the left side of the top plate 3. A first electric push rod 5 is fixed to both the support plate 1 and the top plate 3. The telescopic end of the first electric push rod 5 is fixed to the rear baffle 4. An electric slide rail is located on the right side of the support plate 1, with two electric sliders mirror-image distributed front to back. A barrier gate 6 is fixed to each of the two electric sliders on the electric slide rail. The two side plates 2 are located between the two barrier gates 6 and the rear baffle 4. Each side plate 2 has... The first sliding frame 7 is slidably connected. Each first sliding frame 7 has an L-shaped cross-section. Two electric slide rails are arranged in a mirror image on the first sliding frame 7. Electric sliders are arranged in the two electric slide rails on the first sliding frame 7. The electric slider in the left electric slide rail on the first sliding frame 7 is fixedly connected to a first slider 8. The electric slider in the right electric slide rail on the first sliding frame 7 is fixedly connected to a second slider 9. Fastening ropes 10 are fixedly connected between the two first sliders 8 and the two second sliders 9. The fastening ropes 10 are soft elastic high-friction ropes used to fix the cow's tail. The support plate 1 is provided with an adjustment mechanism 11 for detecting the weight of the inoculated cow. The mirror-distributed side plates 2 are jointly provided with a fastening mechanism 12 for fixing the inoculated cow. The rear baffle 4 is provided with an injection switching mechanism 13 for adjusting the injection position.

[0030] Please refer to 2. Figure 4 and Figure 5 The adjusting mechanism 11 includes a load-bearing plate 1101, which is slidably connected to the inner side of the support plate 1. Two sets of first fixed shells 1102 are fixedly connected to the support plate 1, which are mirror-distributed to the left and right. Each set of first fixed shells 1102 consists of two first fixed shells 1102 that are mirror-distributed to the front and back. The first fixed shell 1102 is slidably connected to a first piston rod 1103, and a spring is provided between the two. The first piston rod 1103 is fixedly connected to the lower side of the load-bearing plate 1101. A transfer shell 1104 is fixedly connected to the front side of the support plate 1. The four first fixed shells 1102 and the transfer shell 1104 are all connected through pipes. Two telescopic rods 1105 are fixedly connected to the upper side of the support plate 1, which are mirror-distributed to the front and back. In the initial state, both telescopic rods 1105 are in the extended state. The fixed part of the telescopic rod 1105 is connected to the transfer shell 1104 through a pipe. The telescopic end of the telescopic rod 1105 is fixedly connected to the adjacent first sliding frame 7.

[0031] Please see Figure 1 and Figure 2The fastening mechanism 12 includes two second electric push rods 1201 distributed in a front-to-back mirror image. The two second electric push rods 1201 are respectively fixed to adjacent side plates 2. The side plates 2 are slidably connected to second sliding frames 1202 which are fixed to the telescopic ends of the adjacent second electric push rods 1201. Fastening straps 1203 are fixed to the opposite sides of the two second sliding frames 1202. The fastening straps 1203 are soft and elastic fastening straps used to flexibly fix the vaccinated cattle. The two fastening straps 1203 are located between the two side plates 2.

[0032] Please see Figure 1 and Figures 6-8 The injection switching mechanism 13 includes a third sliding frame 1301, which is slidably connected to the rear baffle 4. A second fixed shell 1302, connected to the transfer shell 1104 via a pipe, is fixedly connected to the left side of the rear baffle 4. A second piston rod 1303, fixedly connected to the third sliding frame 1301, is slidably sealed to the second fixed shell 1302. A first electric rotating shaft 1304 is located on the right side of the third sliding frame 1301. A first fixed frame 1305 is fixedly connected to the right side of the first electric rotating shaft 1304. Two second electric rotating shafts 1306 are centrally symmetrically distributed on the first fixed frame 1305. The center of symmetry of the rotating shaft 1306 coincides with the axis of the first electric rotating shaft 1304. A third fixed shell 1307 is fixedly connected to the second electric rotating shaft 1306. The third fixed shell 1307 is made of soft and elastic material and is used to load vaccine needles. A mechanical claw 1308 is provided on the top plate 3. The mechanical claw 1308 is existing technology and is used to transfer vaccine needles. It will not be described in detail here. The vaccine needle is provided on the mechanical claw 1308. A storage shell 1309 is fixedly connected to the upper side of the top plate 3. The storage shell 1309 is provided with two mirror-distributed storage chambers. The two storage chambers are respectively for storing unadministered vaccines and for storing administered vaccines.

[0033] Please see Figure 8 and Figure 9 A third electric push rod 1310 is fixedly connected to the second electric rotating shaft 1306. A second fixing frame 1311 that contacts and cooperates with the adjacent vaccine needle is fixedly connected to the telescopic end of the third electric push rod 1310. The fixing part of the third electric push rod 1310 is slidably connected to the adjacent second fixing frame 1311 through a mounting rod. A fourth sliding frame 1312 is slidably connected to the end of the telescopic end of the second fixing frame 1311 that is fixed to the telescopic end of the third electric push rod 1310. The fourth sliding frame 1312 is provided with a soft high-friction material for fixing the vaccine. A tension spring is provided between the end of the fourth sliding frame 1312 and the end of the adjacent second fixing frame 1311. In the initial state, the tension spring between the second fixing frame 1311 and the fourth sliding frame 1312 is in a stretched state, and the fourth sliding frame 1312 is in a limited cooperation with the adjacent vaccine needle.

[0034] When this device is needed to vaccinate cattle, the user first transports it to the cattle farm, dividing the farm into an unvaccinated area and a vaccinated area, with the unvaccinated area to the left of the device and the vaccinated area to the right. The user then herds all the cattle requiring vaccination to the unvaccinated area. Next, the user prepares a sufficient quantity of vaccine and places it orderly in the unvaccinated vaccine storage chamber of storage shell 1309. The user controls the mechanical gripper 1308 to pick up a vaccine and rotate it 180°. Then, the user controls the mechanical gripper 130... 8. The vaccine is pressed down into the upper third fixed shell 1307. During this process, the front of the vaccine is also squeezed and stuck in the upper fourth sliding frame 1312. The user controls the mechanical claw 1308 to release the vaccine and reset it. Then, the first electric rotating shaft 1304 is rotated. The first electric rotating shaft 1304 drives the first fixed frame 1305 to rotate 180°. The first fixed frame 1305 drives the two second electric rotating shafts 1306 and the two third fixed shells 1307 to rotate 180°. At this time, the upper third fixed shell 1307 drives the vaccine to rotate to the lower side. The preparation work is now complete.

[0035] After preparation, the user drives the cow to be vaccinated (hereinafter referred to as the vaccinated cow) along the inclined surface on the left side of the support plate 1 to the upper side of the load-bearing plate 1101 until the entire cow is positioned between the two side plates 2. The cow squeezes and drives the load-bearing plate 1101 to move downwards. The load-bearing plate 1101 drives the four first piston rods 1103 to move downwards together, simultaneously squeezing the springs between the first piston rods 1103 and the adjacent first fixed shells 1102. The hydraulic oil in the four first fixed shells 1102 flows through pipes to the transfer shell 1104. The transfer shell 1104... The internal hydraulic oil flows through the pipes to the two telescopic rods 1105. The telescopic ends of the two telescopic rods 1105 retract and drive the two first sliding frames 7, i.e., the parts on them (two first sliders 8, two second sliders 9 and two fastening ropes 10), to move to the left together. That is, the distance the two first sliding frames 7 move to the left is proportional to the size of the inoculated cattle (the larger the size of the inoculated cattle, the greater the distance the two first sliding frames 7 move to the left), until the load-bearing plate 1101 stops moving downward and the two first sliding frames 7 stop moving to the left. At this time, the root of the cattle's tail is located between the two fastening ropes 10.

[0036] During the downward movement of the load-bearing plate 1101, some of the hydraulic oil in the transfer shell 1104 moves through the pipeline to the second fixed shell 1302. The hydraulic oil squeezes and drives the second piston rod 1303 to move upward. The second piston rod 1303 drives the third sliding frame 1301 and its parts to move upward until the load-bearing plate 1101 stops moving downward. At this time, the third sliding frame 1301 and its parts stop moving upward (that is, the upward movement distance of the third sliding frame 1301 and its parts is proportional to the body size of the inoculated cattle). Through the cooperation of the load-bearing plate 1101 and the first fixed shell 1102, the vaccination position of the vaccine is synchronously and automatically adjusted according to the body size of the inoculated cattle, thus expanding the applicability of this device.

[0037] After the load-bearing plate 1101 stops moving downwards, the user controls the telescopic end of the first electric push rod 5 to retract. The telescopic end of the first electric push rod 5 drives the rear baffle 4 and its parts to move downwards until the lower side of the rear baffle 4 contacts and presses against the upper side of the load-bearing plate 1. At this time, the horizontal plane where the lower vaccine needle is located is within the injection range of the cow's tail. The user controls the telescopic end of the first electric push rod 5 to stop retracting. At this time, the isolation of the vaccinated cow is completed.

[0038] After the two first sliding frames 7 stop moving to the left (i.e., the vaccinated cattle are isolated), the user controls the slider on the left electric slide rail inside the two first sliding frames 7 to move the two first sliders 8 and the left fastening rope 10 upward. As the left fastening rope 10 moves upward, it contacts and squeezes the cow's tail, causing the tail to swing upward until the vaccination site (tail root vaccination site) is exposed. The user then controls the slider on the left electric slide rail of the first sliding frame 7 to stop moving upward, and the left fastening rope 10 stops moving upward. During the above process, the left fastening rope 10 is compressed and stretched, causing it to bend. Subsequently, the user controls the two first sliding frames 7 to move upward. The slider on the right electric slide rail of the sliding frame 7 drives the two second sliders 9 and the right fastening rope 10 to move downwards until the right fastening rope 10 moves downwards and squeezes the cow's tail. At this time, the right fastening rope 10 also bends under the reaction force of the cow's tail. The left and right fastening ropes 10 work together to fix the cow's tail. At this time, the cow's tail is fixed. Through the cooperation of the first sliding frame 7 and the fastening rope 10, the position of the cow's tail is adjusted and fixed according to the body shape of the cow being vaccinated. This eliminates the need for others to assist in fixing the cow's tail during the entire vaccination process, thereby cutting off the risk of Brucella infection at the source and reducing the risk of infection for vaccination personnel.

[0039] During vaccination, the cow's body is not fixed in place. If the pain during the injection causes the cow to move around, it can lead to problems in the injection process, and may even cause the vaccine needle to break (or a large wound to appear at the injection site on the cow's tail), thereby affecting the effectiveness of the vaccine and the cow's health.

[0040] During the aforementioned process of securing the cow's tail, the user simultaneously controls the retraction of the telescopic ends of the two second electric push rods 1201. The telescopic ends of the two second electric push rods 1201 drive the two second sliding frames 1202 to move in opposite directions. The two second sliding frames 1202 drive the two fastening straps 1203 to move in opposite directions. As the two fastening straps 1203 move in opposite directions, they gradually reduce the cow's movement space until the cow comes into contact with the fastening straps 1203. As the two fastening straps 1203 gradually move in opposite directions, they are stretched by the pressure of the cow's body, thus positioning and securing the cow. This continues until the telescopic ends of the two second electric push rods 1201 are completely retracted. At this point, the cow is secured. The cow is secured by the mirror-distributed fastening straps 1203 moving in opposite directions. The entire securing process is a gentle and gradual process to secure the cow, minimizing any fright.

[0041] After the cow is secured for vaccination, the user controls the lower second electric rotating shaft 1306 to rotate. The second electric rotating shaft 1306 drives the lower third fixing shell 1307 and the vaccine needle to rotate until the angle between the vaccine needle tip and the cow's tail injection position reaches the injection angle. The user then controls the extension end of the third electric push rod 1310 to extend. The extension end of the third electric push rod 1310 drives the second fixing frame 1311 to move to the right. The second fixing frame 1311 drives the fourth sliding frame 1312 to move to the right via a tension spring. The fourth sliding frame 1312 drives the vaccine needle to move towards the cow's tail injection site until the vaccine needle tip contacts and penetrates the cow's tail injection site. The vaccine needle injection cartridge stops moving upon contact with the cow's tail. As the extension end of the lower third electric push rod 1310 continues to extend, the third electric push rod 1310... The telescopic end drives the second fixed frame 1311 to continue moving towards the injection site at the cow's tail, while simultaneously stretching the tension spring of the fourth sliding frame 1312. The second fixed frame 1311 contacts and compresses the vaccine needle push rod. As the second fixed frame 1311 continues to move, it compresses and drives the vaccine needle push rod to move towards the injection site at the cow's tail, simultaneously injecting the vaccine inside the vaccine needle into the cow's tail through the needle tip. After the injection is completed, the user controls the telescopic end of the third electric push rod 1310 to retract and drive the fourth sliding frame 1312 and the vaccine needle to reset. At this point, the vaccine injection is complete. Through the cooperation of the third electric push rod 1310 and the fourth sliding frame 1312 with the vaccine needle, contactless vaccine injection is completed for the vaccinated cow, preventing angle deviations that occur during manual vaccination and improving the reliability of the vaccination device.

[0042] After the vaccine injection is completed, the user controls two sliders in the electric slide rail on the support plate 1 to move in opposite directions. These two sliders then drive two blocking gates 6 to move in opposite directions until the two blocking gates 6 no longer obstruct the vaccinated cow. The user then controls the two sliders on the electric slide rail on the support plate 1 to stop moving. The user then drives the vaccinated cow to the right, off the upper side of the support plate 1101, and moves it to the vaccine injection area along with the right-side inclined plate of the support plate 1. The support plate 1101 moves upward and resets under the action of the springs between the four first fixed shells 1102 and the four first piston rods 1103. The oil flow reverses, and the user controls the two sliders on the electric slide rail on the support plate 1 to move in opposite directions. The two blocking gates 6 are moved in opposite directions and reset. Then, the extension end of the first electric push rod 5 is extended. The extension end of the first electric push rod 5 drives the rear baffle 4 and its parts to reset. The user repeats the above steps to install the vaccine needle into the upper third fixed shell 1307. The user controls the first electric rotating shaft 1304 to rotate the vaccine needle that has been injected on the lower side to the upper side. Then, the user controls the mechanical claw 1308 to remove the injected vaccine needle and place it in the vaccine storage chamber of the storage shell 1309. At this time, a single vaccine injection is completed. The user repeats the above steps to vaccinate all the cows until all the cows have been vaccinated. At this time, the use of this device is completed.

[0043] Studies have shown that cattle experience increased stress in enclosed environments. If cattle are further restrained, they may struggle violently, which can have the opposite effect and interfere with the vaccination process.

[0044] Example 2: Based on Example 1, please refer to section 2. Figure 10 and Figure 11It also includes a fixing mechanism 14 for fixing the head of the inoculated cow. The fixing mechanism 14 is set on the mirror-distributed barrier gates 6. The fixing mechanism 14 includes two rotating columns 1401 distributed in a mirror-distributed manner. The two rotating columns 1401 are rotatably connected to the adjacent barrier gates 6. A feed trough for storing feed is provided on the right side of the barrier gates 6. Limiting rods 1402 are fixed to the opposite sides of the two rotating columns 1401. The two limiting rods 1402 are centrally symmetrically distributed. The center of symmetry of the two limiting rods 1402 coincides with the midpoint of the line connecting the two rotating columns 1401. A third fixing frame 1403 is fixed to the opposite side of the two rotating columns 1401. The third fixing frame 1403 is used for... To slow down the descent speed of the adjacent limiting rod 1402, a fifth sliding frame 1404 is slidably connected to the right side of the barrier gate 6 via an installation rod. The fifth sliding frame 1404 consists of an L-shaped plate and a cylindrical rod. A fourth electric push rod 1405 is fixedly connected to the barrier gate 6. The telescopic end of the fourth electric push rod 1405 is fixedly connected to the L-shaped plate portion of the adjacent fifth sliding frame 1404. The cylindrical rod portion of the fifth sliding frame 1404 is in a limiting engagement with the adjacent limiting rod 1402. A fixing rod 1406 is fixedly connected to the right side of the third fixing frame 1403. Two limiting frames 1407, which are distributed in a front-to-back mirror image, are fixedly connected to the upper side of the bearing plate 1. The limiting frames 1407 are in a pressing engagement with the adjacent fixing rod 1406.

[0045] When the user controls this device to vaccinate the cattle, the user loads sufficient feed into the feed trough on the right side of the two barrier gates 6. Simultaneously, the user prepares the vaccine. After preparation, the user drives the cattle onto the load-bearing plate 1101. At this time, the cattle are attracted by the feed and pass their heads through the gap between the two barrier gates 6 and the two limit rods 1402 until the cattle's heads can reach the feed. The user then controls the extension and retraction ends of the two fourth electric push rods 1405 to extend, which in turn drive the two fifth... The sliding frame 1404 moves to the right until the fifth sliding frame 1404 loses its restriction on the adjacent limiting rod 1402. At this time, the limiting rod 1402 swings downward around the rotation center of the rotating column 1401 under the action of gravity. The rotating column 1401 drives the adjacent third fixed frame 1403 and the adjacent fixed rod 1406 to swing upward until the two limiting rods 1402 contact the neck of the cow being vaccinated. At this time, the two limiting rods 1402 restrict the head of the cow being vaccinated, thereby preventing the cow from swinging too much due to pain during vaccination, which would affect the vaccine injection.

[0046] After the vaccine injection is completed, the user controls the two blocking gates 6 to move in opposite directions and then reset. Taking the front blocking gate 6 as an example, the blocking gate 6 drives the rotating column 1401, the limiting rod 1402, the third fixed frame 1403, the fifth sliding frame 1404, the fourth electric push rod 1405, and the fixed rod 1406 to move forward together. During this process, the front fixed rod 1406 is squeezed by the limiting frame 1407 and gradually swings downward. The fixed rod 1406 drives the third fixed frame 1403 to swing downward synchronously, and the third fixed frame 1403 drives... The rotating column 1401 and the limiting rod 1402 rotate and reset. After the limiting rod 1402 resets, the user controls the extension end of the fourth electric push rod 1405 to retract. The extension end of the fourth electric push rod 1405 drives the fifth sliding frame 1404 to reset and re-limit the limiting rod 1402. The limiting rod 1402 and the fifth sliding frame 1404 cooperate to limit the head of the vaccinated cow. At the same time, the feed in the feed trough on the barrier gate 6 diverts the attention of the vaccinated cow, improving the stability of the vaccinated cow during vaccination.
