Abstract
Description
Technical Field
[0001] This utility model belongs to the field of poultry disease prevention technology, and in particular relates to a highly efficient intramuscular injection device for poultry vaccines. Background Technology
[0002] Common poultry fall into two main categories: chickens and ducks. Chickens and ducks are highly valued by consumers for their nutritional and economic benefits and are widely raised in my country. However, various diseases emerge during their cultivation, posing a threat to farmers' economic well-being. Therefore, farmers often administer multiple vaccinations to chickens, ducks, and other poultry during the rearing process. Currently, vaccinations are still administered manually using syringes. Manual injection requires skilled operators, who must precisely control the depth and angle of the needle insertion. With large numbers of poultry on farms, operators must control the birds during injection, increasing the risk of missed vaccinations. Unvaccinated birds are more susceptible to disease, compromising the safety of other poultry. Furthermore, operators are prone to fatigue after prolonged injection sessions, compromising the effectiveness and accuracy of vaccinations. Manual injection is labor-intensive and costly, hindering the development of poultry farming. Utility Model Content
[0003] To address the problems in related technologies, this application provides a highly efficient intramuscular injection device for poultry vaccines, which solves the problems of requiring certain skills and incurring high labor costs for manual injection of poultry vaccines.
[0004] The technical solution is as follows:
[0005] A highly efficient intramuscular injection device for poultry vaccines includes an inclined stepping support and a PLC controller. The front end of the stepping support is provided with an injection device and a propulsion device for driving the injection device to move. One end of the injection device is connected to the propulsion device, and one end of the stepping support is provided with a neck restraint.
[0006] The neck restraint includes a first connector, a second connector, and a neck fixation frame. The second connector and the stepping bracket are fixedly connected. The bottom end of the second connector is hinged to the first connector. The neck fixation frame is disposed on the first connector and faces the injection device. The second connector is provided with a proximity switch for detecting the position of the first connector.
[0007] When not subjected to external force, the top surface of the hinged first connector is attached to the inner wall of the second connector, and the proximity switch is away from the side of the first connector. When the first connector is lifted upward by an external force, the side of the first connector and the proximity switch come into contact.
[0008] When the device is in a non-injection state (i.e., without external force), due to its greater weight, one side of the first connecting member's top surface will adhere to the inner wall of the second connecting member via the hinged first and second connecting members. At this time, the proximity switch is away from the side of the first connecting member. When the operator places the poultry on the neck support, manually secures the poultry, and lifts the first connecting member upwards, the position of the first connecting member changes. The side of the first connecting member that was adhering to the inner wall of the second connecting member is no longer adhering, and the side of the first connecting member abuts against the proximity switch. The operator stops lifting, and the PLC controller controls the propulsion device to start running, pushing the injection device to inject the vaccine into the poultry on the neck support in a timely manner, ensuring injection efficiency. Through mechanically controlled injection, the operator does not need injection skills, thus saving the cost of hiring experienced operators. In addition, the simple mechanical structure can ensure injection efficiency and accuracy.
[0009] Furthermore, the second connector includes a second fixing block and two second fixing plates with identical structures. The second fixing block is connected to the stepper bracket, and the two second fixing plates are spaced apart on the other side of the second fixing block. The proximity switch is disposed on the second fixing block between the two second fixing plates.
[0010] The first connector includes a first fixing block and a first fixing plate. The first fixing plate is disposed on the first fixing block. Both the first fixing plate and the two second fixing plates are provided with through holes. A rotating shaft is disposed between the two second fixing plates. The first fixing plate is movably disposed between the two second fixing plates through the rotating shaft. Both sides of the rotating shaft are threaded with second nuts.
[0011] With the above technical solution, when the device is not subjected to external force, the weight of the first fixing block causes the top surface of the first fixing plate to adhere to the bottom surface of the second fixing plate. When the operator manually lifts the first connector, the top surface of the first fixing plate no longer adheres to the second fixing plate. The method of switching between the two states is simple and easy to operate.
[0012] Furthermore, the propulsion device includes a first drive motor, a propeller, a slide rail, and a meshing mechanism. The first drive motor is fixedly mounted on one side of the top of the stepper bracket. The meshing mechanism includes a meshing gear and a rack. The gear is sleeved on the output shaft of the first drive motor. The slide rail is located on the side of the stepper bracket where the injection device is located. The slide rail has a groove. One side of the propeller has a first slider that matches the groove. The propeller is located on the side of the slide rail via the first slider. The top end of the propeller near the slide rail has a first groove. The rack is located in the first groove and on the side of the slide rail. The piston handle at one end of the injection device is connected to the propeller.
[0013] The first drive motor and gear are connected, and the first drive motor drives the gear to rotate. The rack is set in the first groove at the top of the pusher when it meshes with the gear. Then the pusher moves along the slide rail through the first slider. The pusher is connected to the piston handle. Driven by the first drive motor, the pusher moves the piston handle towards the needle, thereby completing the injection of the vaccine. The injection device has a simple structure and is easy to operate, thus ensuring injection efficiency. The injection process does not require manual assistance, thereby saving labor costs.
[0014] Furthermore, the propulsion device includes a second drive motor and a lead screw assembly. The lead screw assembly includes a first lead screw and a first nut. The first nut is threaded onto the first lead screw. The second drive motor is fixedly mounted on one end of the stepper bracket. The output shaft of the second drive motor is connected to the first lead screw. The first nut is connected to the piston handle in the injection device.
[0015] By setting up a second drive motor and a lead screw device, the rotational motion of the second drive motor can be converted into linear motion. The first nut moves along the first lead screw due to its threaded connection, thereby driving the piston handle of the injection device to move. The propulsion device has a simple structure, which can not only improve injection efficiency, but also save injection time and labor costs.
[0016] Furthermore, a second groove is provided at one end of the first connector, and the neck fixing frame includes a curved shell and a mounting base. The curved shell is disposed on the top of the mounting base, and the mounting base is disposed in the second groove. An injection groove for placing poultry is provided on the curved shell, and the lower part of the injection groove corresponds to the position of the needle on the injection device.
[0017] By setting up the injection slot, the operator places the poultry in the injection slot. In addition to making it easier to control the poultry, the contact point between the poultry and the injection slot can be used as a force point to lift the first connecting piece upwards. This makes the distance between each point on the side of the first fixing piece and the proximity switch consistent, and then the PLC controller starts to inject the vaccine. After eliminating the manual injection step, the operator only needs to perform simple operations, which not only ensures that every poultry is injected, but also saves labor costs.
[0018] Furthermore, one end of the injection device is provided with a liquid inlet.
[0019] The addition port allows for the connection of an external liquid dispensing device, enabling timely replenishment of the injection device without moving it, thus ensuring the success of the next vaccine injection. The liquid dispensing method is simple and easy to operate, simplifying the operation process and saving labor costs.
[0020] Furthermore, the piston handle at one end of the injection device is connected to the pusher, and the other end of the injection device is provided with a second slider that matches the slide groove. The injection device is mounted on one side of the slide rail via the second slider.
[0021] By setting the second slider, the injection device will generate a certain displacement during the process of the piston handle being pushed. The injection device can move along the slide rail through the second device to ensure the safety of the injection device.
[0022] Furthermore, a support plate is provided at the bottom of one end of the stepping bracket, and the plane at the bottom of the support plate is higher than the plane at the bottom of the first connector.
[0023] By setting a higher support plate, the entire device is placed at an angle, with the side containing the first drive motor at a higher position. At this time, because the neck fixing frame and the first connecting piece are too heavy, the first fixing plate and the second fixing plate form a certain angle. When the poultry is fixed on the neck fixing frame between the injection slots and the first connecting piece is lifted upwards, the positional change of the first fixing plate can be detected more clearly, thereby ensuring that the injection device can inject the medicine into the poultry in a timely manner and ensure injection efficiency.
[0024] Furthermore, both the first and second sliders have latches movably installed on the side closest to the slide rail.
[0025] With the locking mechanism in place, when the first drive motor is stopped, the first and second sliders may move along the slide rail, potentially affecting or damaging the injection device. When the first drive motor stops, the position of the locking mechanism can be adjusted to lock between the first slider and the slide rail, and between the second slider and the slide rail, thus stopping the first and second sliders on the slide rail and ensuring the safety of the device.
[0026] The beneficial effects of this utility model are as follows: By using the hinged first and second connecting parts, when the device is not subjected to external force, because the neck fixing frame is set on the first connecting part, the first connecting part, which is hinged to the second connecting part, has a relatively large weight. One side of the top surface of the first connecting part is attached to the inner wall of the second connecting part. At this time, the proximity switch is away from the side of the first connecting part. When the operator manually places the poultry on the injection tank, manually fixes the poultry and lifts the first connecting part upwards, that is, under the state of using external force, the position of the first connecting part changes significantly. The side of the first connecting part attached to the inner wall of the second connecting part will move away, and the side of the first connecting part will abut against the proximity switch. When the operator stops lifting, the PLC controller controls the propulsion device to start running, pushing the injection device to inject the vaccine into the poultry on the neck fixing frame in a timely manner, ensuring injection efficiency. After the injection is completed, the operator removes the poultry and the external force, and the first connecting part returns to its original position due to gravity. One side of the top surface of the first connecting part continues to be attached to the inner wall of the second connecting part. Through mechanically controlled injection, the operator does not need to have injection skills, thus saving the cost of hiring operators with injection experience.
[0027] In addition, the device has a simple structure and is easy to operate, which can ensure the efficiency and accuracy of injection. After eliminating the step of manual injection, the operator only needs to perform some simple operations, which can not only ensure that every poultry is injected, but also save labor costs.

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this invention as detailed in the appended claims.
[0034] Example 1:
[0035] As attached Figure 1 As shown, the poultry vaccine high-efficiency intramuscular injection device includes an inclined stepping bracket 1 and a PLC controller. A support plate 12 is provided at the bottom of one end of the stepping bracket 1. The support plate 12 is triangular in shape and has many holes. This reduces the weight of the device while ensuring that the function of the device is not affected. In the absence of external force, the top surface of the hinged first connector 3 is attached to the inner wall of the second connector 4, and the side of the first connector 3 is away from the proximity switch. When the first connector 3 is lifted upward by an external force, the side of the first connector 3 abuts against the proximity switch.
[0036] The front end of the stepper bracket 1 is provided with an injection device 2 and a propulsion device for driving the injection device 2 to move. One end of the injection device 2 is connected to the propulsion device. The propulsion device includes a first drive motor 6, a pusher 7, a slide rail 8, and a meshing mechanism. A PLC controller is used to control the start and stop of the first drive motor 6. The first drive motor 6 is fixedly installed on one side of the top of the stepper bracket 1. The meshing mechanism includes a meshing gear 9 and a rack 10. The gear 9 is sleeved on the output shaft of the first drive motor 6. The slide rail 8 is provided on the side of the stepper bracket 1 where the injection device 2 is located. The slide rail 8 is provided with a sliding groove. The sliding groove is located on the side of the slide rail 8. One side of the pusher 7 is provided with a first slider that matches the sliding groove. The pusher 7 is located on the side of the slide rail 8 through the first slider. The top end of the pusher 7 is located near the slide rail 8. The device has a first groove, and a rack 10 is set in the first groove and is located on the side of the slide rail 8. When the first drive motor 6 is started, the output shaft of the first drive motor 6 drives the gear 9 to rotate. The gear 9 and the rack 10 are meshed, and the gear 9 will mesh with each tooth on the rack 10 in sequence. The rack 10 drives the first slider to move along the slide rail 8. The piston handle at one end of the injection device 2 is connected to the pusher 7. The pusher 7 then pushes the piston rod to move towards the needle in the injection device 2, so as to push out the vaccine and complete the injection. The other end of the injection device 2 is provided with a second slider that is compatible with the groove. The injection device 2 is set on one side of the slide rail 8 through the second slider. During the injection process, the injection device 2 moves to a certain extent. The injection device 2 moves on the slide rail 8 through the first slider to ensure the safety of the injection device 2.
[0037] One end of the injection device 2 is provided with a liquid inlet 11, which is located on the syringe. The liquid inlet 11 can be connected to an external liquid dispensing device, which can be connected to a PLC controller. After the vaccine injection in the injection device 2 is completed, the PLC controller sends a command, and the external liquid dispensing device starts to input the vaccine. The injection device 2 does not need to be removed before the vaccine is drawn. The structure is simple and easy to operate, saving a lot of operation time and thus improving injection efficiency.
[0038] A neck restraint is provided at one end of the stepper bracket 1. The neck restraint includes a first connector 3, a second connector 4, and a neck fixing frame 5. The second connector 4 is fixedly connected to the stepper bracket 1. The bottom end of the second connector 4 is hinged to the first connector 3. After hinge, one edge of the top surface of the first connector 3 is attached to the inner wall of the second connector 4. The neck fixing frame 5 is disposed on the first connector 3 and faces the injection device 2. A proximity switch for detecting the position of the first connector 3 is provided on the second connector 4. The proximity switch is connected to a PLC controller. The second connector 4 includes a second fixing block and two second fixing plates with identical structures. The second fixing block is connected to the stepper bracket 1. The two second fixing plates are spaced apart at the first... On the other side of the two fixing blocks, the first connecting member 3 includes a first fixing block and a first fixing plate. The first fixing plate is disposed on the first fixing block. Both the first fixing plate and the two second fixing plates are provided with through holes. A rotating shaft is provided between the two second fixing plates. The first fixing plate is movably disposed between the two fixing plates through the rotating shaft. The two sides of the rotating shaft are threaded with second nuts. The first connecting member 3 can rotate through the rotating shaft on the first fixing plate. A second groove is provided at one end of the first connecting member 3. The neck fixing frame 5 includes a curved shell and a mounting base. The curved shell is disposed on the top of the mounting base. The mounting base is disposed in the second groove. An injection groove for placing poultry is opened on the curved shell. The lower part of the injection groove corresponds to the position of the needle on the injection device 2.
[0039] When the device is not subjected to external force, i.e., when no poultry is placed in the injection tank, the bottom plane of the support plate 12 is higher than the bottom plane of the first connecting member 3. At this time, the entire device is set in an inclined state, with the side with the propulsion device being much higher than the needle position of the injection device 2. The first connecting member 3 and the second connecting member 4 are hinged by a rotating shaft. Because the neck fixing bracket 5 is set on the first connecting member 3, the weight of the first connecting member 3 hinged to the second connecting member 4 is relatively large. Under the influence of gravity, the edge of the top surface of the first fixing plate near the right side is attached to the bottom surface of the second fixing member located above. At this time, the first connecting member 3 is away from the proximity switch. When injection is required, the operator places the poultry in the injection tank and manually fixes the poultry. The first connector 3 is then lifted upwards, causing a significant change in its position. The edge of the first connector 3 that was attached to the second fixing plate slowly moves away. When the side of the first connector 3 comes into contact with the proximity switch, the PLC controller controls the propulsion device to start running, pushing the injection device 2 to inject the vaccine into the poultry on the neck fixing frame 5 in a timely manner, ensuring injection efficiency. Through mechanically controlled injection, the operator does not need to have injection skills, thus saving the cost of hiring operators with injection experience. After the injection is completed, the operator removes the poultry from the injection slot, and the first connector 3 loses external force. Due to the greater gravity, the first connector 3 once again has one edge on the top surface of the first fixing plate attached to the inner wall of the second connector 4.
[0040] Both the first and second sliders have latches 13 movably installed on the side closest to the slide rail 8. When vaccine injection is not required, the first drive motor 6 will be in a stopped state. Without the pulling force, the first and second sliders will move along the slide rail 8, which may affect or damage the injection device 2. When the first drive motor 6 stops, the position of the latches 13 is adjusted. Originally, the latches 13 were located at the top of the first and second sliders. Now, they are pushed to the side of the first and second sliders, so that they are locked between the first slider and the slide rail 8, and between the second slider and the slide rail 8, ensuring that the first and second sliders stop on the slide rail 8, thereby ensuring the safety of the device.
[0041] Example 2:
[0042] As attached Figure 2 As shown, the poultry vaccine high-efficiency intramuscular injection device includes an inclined stepping bracket 1 and a PLC controller. A support plate 12 is provided at the bottom of one end of the stepping bracket 1. The support plate 12 is triangular in shape and has many holes. This reduces the weight of the device while ensuring that the function of the device is not affected. In the absence of external force, the top surface of the hinged first connector 3 is attached to the inner wall of the second connector 4, and the side of the first connector 3 is away from the proximity switch. When the first connector 3 is lifted upward by an external force, the side of the first connector 3 abuts against the proximity switch.
[0043] The front end of the stepper bracket 1 is provided with an injection device 2 and a propulsion device for driving the injection device 2 to move. One end of the injection device 2 is connected to the propulsion device. The propulsion device includes a second drive motor 14 and a lead screw device. The lead screw device includes a first lead screw 15 and a first nut 16. The first nut 16 is threaded onto the first lead screw 15. The second drive motor 14 is fixedly installed at one end of the stepper bracket 1. The output shaft of the second drive motor 14 is connected to the first lead screw 15. The first nut 16 is connected to the piston handle in the injection device 2. The piston handle is fixedly connected to the bottom of the first nut 16. The PLC controller is used to control the start and stop of the second drive motor 14. After the second drive motor 14 is started, the output shaft of the second drive motor 14 drives the first lead screw 15 to rotate. At this time, the threaded first nut 16 moves horizontally along the first lead screw 15, thereby pushing the piston handle of the injection device 2 towards the needle in the injection device 2, so as to push out the vaccine and complete the injection.
[0044] One end of the injection device 2 is provided with a liquid inlet 11, which is located on the syringe. The liquid inlet 11 can be connected to an external liquid dispensing device, which can be connected to a PLC controller. After the vaccine injection in the injection device 2 is completed, the PLC controller sends a command, and the external liquid dispensing device starts to input the vaccine. The injection device 2 does not need to be removed before the vaccine is drawn. The structure is simple and easy to operate, saving a lot of operation time and thus improving injection efficiency.
[0045] A neck restraint is provided at one end of the stepper bracket 1. The neck restraint includes a first connector 3, a second connector 4, and a neck fixing frame 5. The second connector 4 is fixedly connected to the stepper bracket 1. The bottom end of the second connector 4 is hinged to the first connector 3. After hinge, one edge of the top surface of the first connector 3 is attached to the inner wall of the second connector 4. The neck fixing frame 5 is disposed on the first connector 3 and faces the injection device 2. A proximity switch for detecting the position of the first connector 3 is provided on the second connector 4. The proximity switch is connected to a PLC controller. The second connector 4 includes a second fixing block and two second fixing plates with identical structures. The second fixing block is connected to the stepper bracket 1. The two second fixing plates are spaced apart at the first... On the other side of the two fixing blocks, the first connecting member 3 includes a first fixing block and a first fixing plate. The first fixing plate is disposed on the first fixing block. Both the first fixing plate and the two second fixing plates are provided with through holes. A rotating shaft is provided between the two second fixing plates. The first fixing plate is movably disposed between the two fixing plates through the rotating shaft. The two sides of the rotating shaft are threaded with second nuts. The first connecting member 3 can rotate through the rotating shaft on the first fixing plate. A second groove is provided at one end of the first connecting member 3. The neck fixing frame 5 includes a curved shell and a mounting base. The curved shell is disposed on the top of the mounting base. The mounting base is disposed in the second groove. An injection groove for placing poultry is opened on the curved shell. The lower part of the injection groove corresponds to the position of the needle on the injection device 2.
[0046] When the device is not subjected to external force, i.e., when no poultry is placed in the injection tank, the bottom plane of the support plate 12 is higher than the bottom plane of the first connecting member 3. At this time, the entire device is set in an inclined state, with the side with the propulsion device being much higher than the needle position of the injection device 2. The first connecting member 3 and the second connecting member 4 are hinged by a rotating shaft. Because the neck fixing bracket 5 is set on the first connecting member 3, the weight of the first connecting member 3 hinged to the second connecting member 4 is relatively large. Under the influence of gravity, the edge of the top surface of the first fixing plate near the right side is attached to the bottom surface of the second fixing member located above. At this time, the first connecting member 3 is away from the proximity switch. When injection is required, the operator places the poultry in the injection tank and manually fixes the poultry. The first connector 3 is then lifted upwards, causing a significant change in its position. The edge of the first connector 3 that was attached to the second fixing plate gradually moves away. When the side of the first connector 3 comes into contact with the proximity switch, the PLC controller controls the propulsion device to start running, pushing the injection device 2 to inject the vaccine into the poultry on the neck fixing frame 5 in a timely manner, ensuring injection efficiency. Through mechanically controlled injection, the operator does not need to have injection skills, thus saving the cost of hiring operators with injection experience. After the injection is completed, the operator removes the poultry from the injection slot, and the first connector 3 loses external force. Due to the greater gravity, the first connector 3 once again causes one edge of the top surface of the first fixing plate to attach to the inner wall of the second connector 4.
