Description

Technical Field

[0001] The present invention relates to the technical field of poultry farming, and in particular to a comprehensive automatic immunization machine. Background Art

[0002] In the poultry farming industry, vaccination is a critical step in preventing and controlling infectious diseases, ensuring healthy poultry growth, and improving farming profitability. Traditional poultry vaccination relies primarily on manual procedures, such as intramuscular injections, subcutaneous injections behind the neck, wing membrane punctures, and eye drops. However, manual vaccination methods have numerous drawbacks. Not only are they labor-intensive and inefficient, making them difficult to meet the demands of large-scale farming, but they also face challenges in ensuring the accuracy and consistency of vaccination procedures. Improper handling can easily lead to vaccination failure, increasing the risk of disease infection in poultry.

[0003] With the development of technology, some automated poultry vaccination equipment has appeared on the market, but most of them only have a single vaccination function, such as intramuscular injection or eye drop vaccination. In actual production, farmers often need to vaccinate poultry in multiple ways, which requires the use of multiple devices with different functions. This not only increases equipment procurement costs and floor space, but also makes switching between devices cumbersome, affecting the timeliness and consistency of vaccination. Therefore, there is an urgent need for a vaccination device that can integrate multiple vaccination functions, has a high degree of automation, and is easy to operate to meet the development needs of modern large-scale poultry farming. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a comprehensive automatic immunization machine.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides an integrated automatic immunization machine, comprising a machine base and a controller arranged on the machine base, a poultry intramuscular injection device, a poultry subcutaneous injection device behind the neck, a poultry wing membrane pricking device and a poultry eye drop immunization device. The poultry intramuscular injection device, the poultry subcutaneous injection device behind the neck, the poultry eye drop immunization device and the poultry wing membrane pricking device are controlled by the controller. The poultry intramuscular injection device is used to perform intramuscular injection on poultry, the poultry subcutaneous injection device behind the neck is used to perform subcutaneous injection on poultry, the poultry eye drop immunization device is used to perform eye drop operation on poultry, and the poultry wing membrane pricking device is used to perform pricking injection on the wing membrane of poultry.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: an integrated automatic immunization machine includes a machine base and a controller arranged on the machine base, a poultry intramuscular injection device, a poultry subcutaneous injection device behind the neck, a poultry wing membrane pricking device and a poultry eye drop immunization device. The poultry intramuscular injection device, the poultry subcutaneous injection device behind the neck, the poultry eye drop immunization device and the poultry wing membrane pricking device are controlled by the controller. The poultry intramuscular injection device is used to perform intramuscular injection on poultry, the poultry subcutaneous injection device behind the neck is used to perform subcutaneous injection on poultry, the poultry eye drop immunization device is used to perform eye drop operation on poultry, and the poultry wing membrane pricking device is used to perform pricking injection on the wing membrane of poultry. The present invention integrates a poultry intramuscular injection device, a poultry subcutaneous injection device behind the neck, a poultry wing membrane pricking device and a poultry eye drop immunization device into one, and uniformly controls them by a controller, thereby changing the situation of high labor intensity and low efficiency of traditional manual immunization, greatly improving the working efficiency of immunization, and meeting the needs of large-scale farming for rapid poultry immunization; at the same time, it avoids the problems of inaccurate and poor consistency of immunization operations caused by factors such as fatigue and differences in technical levels during manual operation, effectively guarantees the success rate of immunization, and reduces the risk of poultry contracting diseases. In addition, compared with single-function automated immunization equipment on the market, farmers do not need to purchase multiple devices, which significantly reduces equipment procurement costs and site occupation area; and reduces the number of poultry grabbing times and reduces stress, making the connection between different immunization methods smoother, improving the timeliness and consistency of immunization, and further optimizing the farming production process.

DETAILED DESCRIPTION

[0014] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] like Figures 1 to 17 As shown, an embodiment of the present invention provides an integrated automatic immunization machine, including a machine base 5 and a controller arranged on the machine base 5, a poultry muscle injection device 1, a poultry subcutaneous injection device 2 behind the neck, a poultry wing membrane pricking device and a poultry eye drop immunization device 4. The poultry muscle injection device 1, the poultry subcutaneous injection device 2 behind the neck, the poultry eye drop immunization device 4 and the poultry wing membrane pricking device are controlled by the controller. The poultry muscle injection device 1 is used to perform intramuscular injection on poultry, the poultry subcutaneous injection device 2 behind the neck is used to perform subcutaneous injection on poultry, the poultry eye drop immunization device 4 is used to perform eye drops on poultry, and the poultry wing membrane pricking device is used to perform pricking injection on the wing membrane of poultry.

[0016] By integrating the poultry intramuscular injection device 1, the poultry subcutaneous injection device 2 behind the neck, the poultry wing membrane pricking device and the poultry eye drop immunization device 4 into one and controlling them uniformly by a controller, the situation of high labor intensity and low efficiency of traditional manual immunization has been changed, the working efficiency of immunization has been greatly improved, and the demand for rapid immunization of poultry in large-scale farming has been met; at the same time, the problems of inaccurate and poor consistency of immunization operations caused by factors such as fatigue and differences in technical levels in manual operations have been avoided, the success rate of immunization has been effectively guaranteed, and the risk of poultry infection with diseases has been reduced. In addition, compared with the single-function automated immunization equipment on the market, farmers do not need to purchase multiple devices, which significantly reduces the equipment procurement cost and site area occupied; and the number of times poultry are grabbed is reduced, stress is reduced, and the connection between different immunization methods is smoother, which improves the timeliness and consistency of immunization, and further optimizes the breeding production process.

[0017] In one embodiment, if Figure 1 As shown, in order to facilitate operation and enhance the compactness of the structure, the poultry wing membrane injection device is installed on the poultry neck subcutaneous injection device 2.

[0018] The poultry intramuscular injection device 1 has the same structure as the poultry subcutaneous injection device 2 behind the neck. In the specific embodiment, the poultry subcutaneous injection device 2 is used for specific description, and the poultry intramuscular injection device 1 is not described in detail.

[0019] like Figures 2 to 8 As shown, the poultry neck subcutaneous injection device 2 includes an injection trigger mechanism 24 and an injection propulsion mechanism. The injection propulsion mechanism includes a first injection fixing seat 21, a propulsion power assembly 22 and a syringe 23. The first injection fixing seat 21 is provided with a mounting cavity 211. The syringe 23 is arranged in the mounting cavity 211. The propulsion power assembly 22 includes a motor 221 and a direct push assembly. The syringe 23 is connected to the motor 221 through the direct push assembly. The direct push assembly converts the rotational motion of the output shaft of the motor 221 into linear motion, and applies a force to the syringe 23 in a direct push manner.

[0020] Specifically, the first injection fixture 21 is made of aluminum alloy and has a stepped mounting cavity 211 therein for accommodating the syringe 23 and the propulsion power assembly 22. The mounting cavity 211 includes a syringe 23 accommodating portion and a power assembly mounting portion 413. The inner wall of the syringe 23 accommodating portion is provided with a limiting structure, such as a protrusion or a snap-in block, to ensure the stability of the syringe 23 after installation.

[0021] The power assembly mounting portion 413 is adapted to the motor 221 and is fixed to the motor 221 by bolts.

[0022] The injection propulsion mechanism converts the rotational motion of the motor 221 into linear motion through a direct-push assembly. Compared with the traditional rotary propulsion method, it eliminates the error caused by the rotation gap tolerance and significantly improves the injection accuracy.

[0023] like Figure 3 As shown, the direct push assembly includes a screw, a spline screw 222 and a spline sleeve 223. The screw is connected to the motor 221 in a transmission manner. One end of the screw is fixedly connected to one end of the spline screw 222. The other end of the spline screw 222 is connected to the syringe 23. The spline sleeve 223 is sleeved on the spline screw 222 and connected to the end cover of the motor 221.

[0024] One end of the screw is connected to the rotor (including the screw nut) of the motor 221 via a key connection or a threaded pair. A pulsed current is passed through the stator winding of the motor 221 to generate an alternating magnetic field, which drives the rotor to rotate in steps (or continuously), thereby driving the screw to rotate synchronously. The other end of the screw is connected to the spline screw 222 via a coupling or an integral molding method to compensate for the coaxiality error of the two shafts. The outer surface of the spline screw 222 is machined with multiple splines, which mesh with the spline grooves on the inner wall of the spline sleeve 223. The spline type can be a rectangular spline or an involute spline.

[0025] The inner wall of the spline sleeve 223 is machined with a spline groove that matches the spline screw 222. Its outer diameter transitions with the mounting hole of the first injection fixture 21. The spline sleeve 223 is secured to the end cap of the motor 221 via bolts or a retaining ring to ensure axial positioning accuracy. To reduce frictional resistance, the mating surfaces of the spline screw 222 and the spline sleeve 223 can be surface-treated, such as with hard chrome plating or spray-coated with a friction-reducing coating. Dustproof seals are also provided at both ends of the spline sleeve 223 to prevent the intrusion of dust and liquid medicine.

[0026] When motor 221 is powered and rotated, its rotor (including the screw nut) drives the screw, which in turn rotates the attached spline screw 222. Because spline sleeve 223 is fixed to the end cap of motor 221, it restricts the rotational freedom of spline screw 222, forcing it to move linearly along its axial direction. This linear motion of spline screw 222 is transmitted to syringe 23, pushing syringe 23 to perform the injection operation.

[0027] like Figure 5 As shown, the syringe 23 includes a first injection needle 231, an injection syringe 232, a liquid pushing piston, an injection push rod 233 and a push rod spring 234. The liquid pushing piston is placed in the injection syringe 232, the first injection needle 231 is arranged at the liquid outlet end of the injection syringe 232, one end of the injection push rod 233 is placed in the injection syringe 232 and connected to the liquid pushing piston, the other end of the injection push rod 233 is connected to the spline screw 222, and the push rod spring 234 is sleeved on the injection push rod 233 and abuts against the injection syringe 232.

[0028] A cylindrical cavity is formed inside the injection syringe 232 as a liquid medicine storage area. The front end of the syringe shrinks to form a tapered liquid outlet end, and the outer surface of the liquid outlet end is processed with a standard Luer connector structure for sealing connection with the first injection needle 231; an annular flange or step surface is provided at the rear end to provide a support surface for the push rod spring 234. The liquid pushing piston is molded from an elastic sealing material (such as nitrile rubber, silicone), and is cylindrical as a whole. The outer diameter is precisely matched with the inner diameter of the injection syringe 232, and at least two annular sealing lips are provided on the periphery to ensure that the piston maintains liquid tightness with the inner wall of the syringe during reciprocating motion. The front end face of the piston is designed to be a plane or a slightly convex surface to reduce liquid medicine residue; the rear end face is provided with a connecting hole or a groove to form an interference fit or a snap connection with the connecting structure at the front end of the injection push rod 233.

[0029] A liquid inlet hole is provided on the side of the injection syringe 232, and a liquid inlet pipe is connected to the liquid inlet hole, through which liquid is supplied.

[0030] The injection push rod 233 is a slender rod-shaped structure as a whole. Its front end is provided with a connecting portion (such as a cylindrical protrusion, a claw structure) that matches the liquid pushing piston through an integrated molding or assembly method.

[0031] The push rod spring 234 is a cylindrical compression spring. Its inner diameter is larger than the outer diameter of the injection push rod 233, ensuring it can fit freely around the outside of the push rod. Its outer diameter is smaller than the inner diameter of the rear end of the injection syringe 232 to prevent movement interference. The spring's preload is designed to provide sufficient resistance during injection to balance the flow resistance of the liquid, ensuring smooth injection, and to return the piston to its initial position during the return stroke.

[0032] The first injection needle 231 is made of a medical stainless steel tube, with a sharp bevel ground on the front end and a Luer interface matching the liquid outlet end of the syringe at the rear end, and a sealed connection is achieved by rotation or pressing.

[0033] When the spline screw 222 moves forward in a straight line under the drive of the motor 221, the injection push rod 233 is forced forward, and the liquid pushing piston moves forward in the syringe, compressing the liquid medicine and causing it to be discharged through the first injection needle 231. At this time, the push rod spring 234 is compressed, storing elastic potential energy. When the motor 221 is reversed or the driving force is withdrawn, the push rod spring 234 releases energy, pushing the liquid pushing piston to move back to its initial position. At the same time, negative pressure is formed in the syringe, and the liquid medicine is sucked from the liquid storage bottle through the liquid inlet hole. Throughout the entire process, the sealing lip of the liquid pushing piston always remains in contact with the inner wall of the syringe to prevent liquid medicine from leaking.

[0034] It should be noted that the movement direction of the injection push rod 233 is the same as the movement direction of the spline screw 222. Such a design can control the transmission error within a very small range, effectively ensuring the accuracy of the injection dose.

[0035] like Figure 3 As shown, the direct push assembly further includes an auxiliary push block 224 , the other end of the spline screw 222 is fixedly connected to the auxiliary push block 224 , and the end of the injection push rod 233 away from the injection syringe 232 is fixedly connected to the auxiliary push block 224 .

[0036] Specifically, the auxiliary push block 224 is a block-shaped structure, with a connection portion on one side adapted for the spline screw 222 and a guide structure on the other side for the injection push rod 233. The connection portion can be designed as a threaded hole or a slot, and is fastened to the end of the spline screw 222 via a set screw or clamp to ensure that there is no relative rotation or axial displacement between the two. For example, if the end of the spline screw 222 has an external thread structure, the connection portion of the auxiliary push block 224 is machined with a matching internal thread. After the two are screwed together through a threaded pair, they are further locked with a set screw on the side to prevent loosening.

[0037] The rigid connection between the auxiliary push block 224 and the spline screw 222 enables the driving force output by the motor 221 to be directly and efficiently transmitted to the injection push rod 233 .

[0038] like Figure 6 As shown, the auxiliary push block 224 is provided with a spherical groove 2242, and a guide channel 2241 is extended on one side of the spherical groove 2242 toward the injection syringe 232. The injection push rod 233 is provided with a ball head 2331 at one end away from the injection syringe 232. The injection push rod 233 is placed in the guide channel 2241 and the ball head 2331 is clamped in the spherical groove 2242.

[0039] A spherical groove 2242 is provided on one side of the auxiliary push block 224 at a connection portion adapted to the spline screw 222 . The inner diameter of the spherical groove 2242 forms a precise clearance fit with the outer diameter of the ball head 2331 at the end of the injection push rod 233 .

[0040] When the spline screw 222 is driven by the motor 221 to make axial linear motion, the auxiliary push block 224 moves synchronously, driving the injection push rod 233 to move axially along the guide channel 2241 through the cooperation between the spherical groove 2242 and the ball head 2331. The injection push rod 233 maintains linear motion under the constraint of the guide channel 2241, ensuring that the thrust is effectively transmitted to the liquid pushing piston.

[0041] The injection trigger mechanism 24 includes a first proximity sensor 241 and a first sensing element 242. The first sensing element 242 is movably arranged. The first sensing element 242 has at least a first state that senses the first proximity sensor 241 and a second state that does not sense the first proximity sensor 241. When the first sensing element 242 switches from the second state to the first state, the syringe 23 performs a quantitative injection operation. After the injection is completed, the first sensing element 242 returns to its original state and waits for the next triggered injection.

[0042] Specifically, the first proximity sensor 241 utilizes a Hall effect sensor or microswitch, secured to the first injection fixture 21 via bolts or a slot. The first sensing element 242 is a plate-like or block-shaped structure, hinged to the first injection fixture 21 via a pivot pin in the middle, forming a lever structure that can rotate about the pivot pin. One end (the sensing end) of the first sensing element 242 is positioned opposite the first proximity sensor 241, while the other end (the operating end) extends outside the device to receive an external trigger force.

[0043] When the operating end of first sensing element 242 is subjected to external pressure (such as contact with a poultry's body), first sensing element 242 rotates about its pin, and its sensing end approaches and senses the first proximity sensor 241. First proximity sensor 241 then outputs an electrical signal to the controller. Upon receiving the signal, the controller drives motor 221, driving the spline screw 222 of the injection propulsion mechanism axially, pushing injection plunger 233 forward and injecting the liquid medicine.

[0044] In one embodiment, the first sensing member 242 is provided with a rotating shaft, and the first sensing member 242 is rotatably disposed on the first injection fixing seat 21 via the rotating shaft. A first elastic reset member is provided between the first sensing member 242 and the first injection fixing seat 21. When the first sensing member 242 is pressed and the first sensing member 242 senses the first proximity sensor 241, the syringe 23 performs an injection operation. When the pressing force of the first sensing member 242 is eliminated, the first sensing member 242 is reset under the action of the first elastic reset member.

[0045] The two ends of the rotating shaft are connected to the two side brackets of the first injection fixed seat 21 through bearings or sleeves to form a rotating pair. The connection between the rotating shaft and the first sensing element 242 can be keyed, interference fit or set screw locked to ensure synchronous rotation of the two.

[0046] The first elastic return member is a cylindrical helical compression spring or a torsion spring. When a compression spring is used, one end of the spring abuts against the inner wall step of the first injection fixture 21, and the other end contacts the bottom protrusion of the first sensing member 242. The spring axis is perpendicular to the rotation plane of the first sensing member 242.

[0047] like Figure 8 As shown, the poultry immunization injection device also includes a neck positioner 25 for fixing the neck of the poultry. The neck positioner 25 and the first sensing element 242 are designed as an integral whole or as a split part. The neck positioner 25 includes a curved shell 251, which is connected to the first sensing element 242. The curved shell 251 is provided with an avoidance hole 252 for avoiding the syringe 23 from performing injection.

[0048] The neck positioner 25 consists of a curved shell 251, a connecting assembly, and a fixed structure. Curved shell 251 is molded from a medical-grade flexible plastic (such as thermoplastic elastomer (TPE)) or silicone. Its inner wall curve is designed based on the physiological curvature of the poultry neck, with a radius of curvature of 5-8 cm. This ensures a tight fit and stable support for the necks of chickens, ducks, and other poultry. Curved shell 251 has an axial length of 8-12 cm and a width of 4-6 cm, ensuring coverage of the primary injection area of ​​the neck without interfering with the poultry's movements.

[0049] The escape hole 252 is located in the middle or side of the curved shell 251 and is circular or oval in shape, with rounded edges to prevent scratching the poultry's skin. The location of the escape hole 252 corresponds to the position of the first injection needle 231 of the syringe 23, ensuring that the needle can penetrate the subcutaneous tissue at the back of the poultry's neck vertically, avoiding oblique or accidental insertions.

[0050] During operation, the operator places the curved shell 251 of the neck positioner 25 around the poultry's neck. When the poultry moves, its neck presses against the curved shell 251, causing the first sensing element 242 to rotate about the axis. The first proximity sensor 241 activates the injection propulsion mechanism. The first injection needle 231 passes through the avoidance hole 252 and penetrates the subcutaneous tissue of the neck, completing the vaccine injection.

[0051] It should be noted that whether to install the neck positioner 25 can be selected according to specific usage requirements. For example, in the poultry intramuscular injection device 1, the neck positioner 25 can be omitted, and the first sensor 242 can be directly used to control the injection. When it is necessary to inject the subcutaneous tissue behind the neck of the poultry, the neck positioner 25 can be used.

[0052] The overall working process of the poultry neck subcutaneous injection device 2 is as follows: Taking the injection of subcutaneous tissue behind the neck of poultry as an example, the operator surrounds the curved shell 251 of the neck positioner 25 around the poultry neck, and the inner wall of the curved shell 251 fits the physiological curvature of the poultry neck. At the same time, it is confirmed that the syringe 23 of the injection propulsion mechanism has absorbed sufficient liquid medicine, the push rod spring 234 is in the initial state, and the first proximity sensor 241 and the first sensing element 242 maintain the second non-sensing state.

[0053] The poultry's neck compresses curved shell 251. Since curved shell 251 is connected to first sensing element 242, the force exerted on curved shell 251 drives first sensing element 242 to rotate about its axis. First sensing element 242 is provided with a rotation axis, and the elastic return element between it and first injection fixture 21 is initially preloaded. As first sensing element 242 rotates, its sensing end gradually approaches and senses first proximity sensor 241. In response, first proximity sensor 241 outputs an electrical signal to the controller.

[0054] After receiving an electrical signal from the first proximity sensor 241, the controller activates the motor 221 that drives the injection push mechanism. The output shaft of the motor 221 drives the screw to rotate, which is fixedly connected to the spline screw 222. The splines on the outer periphery of the spline screw 222 engage with the spline grooves of the spline sleeve 223. The spline sleeve 223 is fixed to the end cap of the motor 221, limiting the rotational freedom of the spline screw 222, forcing it to move linearly along the axial direction. The spline screw 222 is connected to the injection push rod 233 via an auxiliary push block 224. The auxiliary push block 224 is equipped with a spherical groove 2242 and a guide channel 2241. The ball head 2331 of the injection push rod 233 is retained in the spherical groove 2242 and placed within the guide channel 2241. The linear motion of the spline screw 222 pushes the auxiliary push block 224, which in turn drives the injection push rod 233 axially forward. The direction of movement of the injection push rod 233 is consistent with that of the spline screw 222. Injection plunger 233 pushes the plunger within syringe 232, squeezing the liquid medicine from the syringe. The liquid medicine then passes through first injection needle 231 and through relief hole 252 in neck locator 25, accurately injecting it into the subcutaneous tissue of the poultry's neck. The precise alignment of relief hole 252 with the needle ensures a smooth injection process.

[0055] When the injection is complete, the poultry moves away, no longer pressing against the curved shell 251, and the external force acting on the first sensing element 242 is eliminated. At this point, the elastic reset element between the first sensing element 242 and the first injection mount 21 releases its elastic potential energy, pushing the first sensing element 242 to rotate in the opposite direction about its axis of rotation, returning it to its second, non-sensing state relative to the first proximity sensor 241. Driven by the push rod spring 234, the injection push rod 233 drives the injection piston backward, creating negative pressure within the syringe, drawing liquid from the reservoir through the liquid inlet port and inlet tube, preparing for the next injection. Simultaneously, the entire device returns to its initial state, awaiting the next trigger.

[0056] like Figures 9 to 13As shown, the poultry wing membrane seeding device includes a second injection fixing seat 31 and a second sensing member 32, a second proximity sensor 33 and a second injection needle 35 provided on the second injection fixing seat 31. The second sensing member 32 is rotatably provided on the second injection fixing seat 31, and the second proximity sensor 33 and the second injection needle 35 are provided side by side; the second sensing member 32 includes a main body 321 and a sensing portion 322. The sensing portion 322 is arranged on a side of the main body 321 close to the second proximity sensor 33. The main body 321 is provided with a through hole 3211 for the needle portion of the second injection needle 35 to pass through. The axis direction of rotation of the second sensing member 32 is perpendicular to the injection direction of the second injection needle 35. The sensing portion 322 has at least a first state in which it senses the second proximity sensor 33 and a second state in which it does not sense the second proximity sensor 33. When the sensing portion 322 switches from the second state to the first state, the second injection needle 35 performs a quantitative injection operation. After the injection is completed, the sensing portion 322 returns to its original state and waits for the next injection trigger.

[0057] The second injection mount 31 can be made of a strong, corrosion-resistant metal (such as stainless steel) or engineering plastic to ensure stability and durability. In this embodiment, the second injection mount 31 is made of stainless steel with a smooth surface treatment to prevent scratches on poultry or operators during operation.

[0058] During actual operation, the operator holds the poultry wing membrane. When the poultry wing membrane contacts the main body 321 and pushes it, the second sensing element 32 rotates around the pin shaft, and the sensing part 322 changes from the second state of non-sensing with the second proximity sensor 33 to the first state of sensing. The second proximity sensor 33 is triggered, and the second injection needle 35 starts the injection operation. The vaccine is injected into the poultry wing membrane through the second injection needle 35.

[0059] Through the coordination of the second sensing element 32 and the second proximity sensor 33, the second injection needle 35 will only inject when the sensing portion 322 senses the second proximity sensor 33, thereby avoiding accidental injections and preventing vaccine waste. This ensures accurate vaccination and improves the effectiveness and success rate of vaccination. For example, in large-scale poultry vaccination processes, this can significantly reduce vaccine waste and lower farming costs. Furthermore, the through-hole 3211 design of the main portion 321 of the second sensing element 32 ensures the stability of the second injection needle 35 during the vaccination process, allowing the needle to accurately penetrate the second sensing element 32 and penetrate the poultry's wing membrane, ensuring consistency in the vaccination depth and reducing damage to the poultry caused by improper vaccination depth.

[0060] In one embodiment, if Figure 13As shown, the main body 321 is in an elongated shape. The upper end of the main body 321 is provided with a rotating shaft hole 3212 rotatably connected to the second injection fixing seat 31 , and the lower end of the main body 321 is provided with a through hole 3211 .

[0061] The upper end of the main body 321 is provided with a rotational axis hole 3212, which is used to achieve a rotational connection with the second injection mount 31. Specifically, the second injection mount 31 is provided with a corresponding rotational groove 311, into which the main body 321 can be fit. A rotational axis mounting hole 3111 is provided at the position of the rotational groove 311 corresponding to the rotational axis hole 3212 of the main body 321. By inserting a pin into the rotational axis mounting hole 3111 and the rotational axis hole 3212, a rotational connection between the main body 321 and the second injection mount 31 is achieved, with the pin as the axis. This rotational connection allows the main body 321 to rotate smoothly about the pin when subjected to external forces (such as the push of a poultry wing membrane), thereby changing the relative position of the sensing portion 322 and the second proximity sensor 33, thereby controlling the injection operation of the second injection needle 35.

[0062] The lower end of the main body 321 is provided with a through hole 3211. This hole 3211 is sized to accommodate the tip of the second injection needle 35 and is designed to pass through it. During use, after the second injection needle 35 passes through the through hole 3211, its tip can be precisely aligned with the poultry's wing membrane for seeding. By observing the position of the through hole 3211, accurate positioning can be achieved quickly and easily, thereby improving injection efficiency.

[0063] The main body 321 is designed to be rotatably connected to the second injection fixing seat 31 through the rotating shaft hole 3212, so that the second sensing element 32 can flexibly rotate around the pin shaft when subjected to the force of the poultry wing membrane, thereby accurately controlling the sensing and non-sensing states of the sensing part 322 and the second proximity sensor 33, and then accurately controlling the injection timing of the second injection needle 35, effectively avoiding vaccine waste or inaccurate vaccination due to misoperation.

[0064] In one embodiment, a second elastic return member is further provided between the rotation slot 311 and the main body 321. The provision of the second elastic return member ensures that the second sensing member 32 can quickly and stably return to its initial position after completing a pricking operation, so as to be ready for the next pricking operation.

[0065] The second elastic return element is a spring. A spring mounting groove 412 is provided within the rotational groove 311 of the second injection fixture 31, corresponding to the position of the main body 321. The spring mounting groove 412 can be located on the sidewall or bottom of the rotational groove 311. A spring connection portion corresponding to the spring mounting groove 412 is provided on the side or bottom of the main body 321. The spring connection portion can be designed as a protrusion or a hook structure. One end of the spring is fixedly installed in the spring mounting groove 412, and the other end is connected to the spring connection portion of the main body 321. When installed, the spring is in a certain state of compression, providing a restoring force for the main body 321.

[0066] When the sensing portion 322 of the second sensing element 32 is pushed by the poultry's wing membrane, the main body 321 rotates about the pin. This further compresses the second elastic return element, storing elastic potential energy. After the pricking operation is complete and the force acting on the sensing portion 322 is removed, the spring releases this elastic potential energy, pushing the main body 321 to rotate in the opposite direction about the pin, rapidly returning the sensing portion 322 to its second, non-sensing state relative to the second proximity sensor 33.

[0067] The second elastic reset member can quickly pull the main body 321 back to the initial position after the sensing part 322 loses the external force, which greatly improves the reset speed and stability, allowing the device to perform continuous pricking operations at a stable rhythm.

[0068] In one embodiment, the sensing portion 322 is extended from a position near the lower end of the main body 321. Such a design enables the sensing portion 322 to sense the second proximity sensor 33 at a suitable position, thereby ensuring smooth operation.

[0069] In one embodiment, if Figure 12 As shown, the second injection fixing seat 31 is provided with a receiving groove 314, and the second proximity sensor 33 is fixed in the receiving groove 314, with the sensed surface of the second proximity sensor 33 facing the sensing portion 322. The second proximity sensor 33 can be fixed by bonding, clamping or screws.

[0070] During actual operation, when the triggering member is pushed by the poultry wing membrane and rotates, the sensing part 322 gradually approaches and senses the sensing surface of the second proximity sensor 33. When the sensing reaches the triggering threshold of the second proximity sensor 33, the second proximity sensor 33 is triggered and sends a signal to the control system of the second injection needle 35 to control the second injection needle 35 to perform the injection operation.

[0071] In one embodiment, the second injection fixture 31 is provided with a first engaging groove 312, into which the second injection needle 35 is engaged. The first engaging groove 312 is provided with first locking holes at the upper and lower sides thereof, and first elastic locking blocks 36 are provided in the first locking holes. When the first elastic locking blocks 36 are tightened, the second injection needle 35 is fastened in the first engaging groove 312.

[0072] The shape and size of the first engaging groove 312 are designed to match the outer contour of the second injection needle 35 to ensure a compatible engagement between the two. For example, if the second injection needle 35 is cylindrical, the first engaging groove 312 is designed as a cylindrical groove. This allows the second injection needle 35 to be smoothly inserted into the first engaging groove 312 while ensuring a certain degree of fit and preventing the second injection needle 35 from shaking within the first engaging groove 312.

[0073] First locking holes are symmetrically disposed on the upper and lower sides of the first engaging groove 312, and the diameter of the first locking holes matches the diameter of the first elastic locking block 36. In this embodiment, the first elastic locking block 36 is in the form of a threaded tube with an elastic rubber head mounted on the head. The length of the threaded tube is selected based on the thickness of the first engaging groove 312 and the material of the second injection needle 35, ensuring that the second injection needle 35 can be securely and elastically engaged within the first engaging groove 312 after installation.

[0074] When installing the second injection needle 35, first place the second injection needle 35 into the first clamping groove 312, then screw the first elastic locking block 36 into the locking hole, and by twisting the first elastic locking block 36, the elastic rubber head of the first elastic locking block 36 presses the second injection needle 35, thereby fastening the second injection needle 35 in the first clamping groove 312; when the second injection needle 35 needs to be replaced, simply pull the second injection needle 35 and overcome the elastic force of the elastic rubber head, and then the second injection needle 35 can be removed for replacement.

[0075] The first elastic locking block 36 utilizes a hexagon socket screw. To install the second injection needle 35, first insert the second injection needle 35 into the first engaging groove 312 to initially secure the second injection needle 35. Then, screw the hexagon socket screw into the first locking hole. By tightening the hexagon socket screw, its end gradually presses against the surface of the second injection needle 35. As the hexagon socket screw is tightened, the friction between the second injection needle 35 and the first engaging groove 312 increases, thereby firmly securing the second injection needle 35 in the first engaging groove 312. To remove the second injection needle 35, simply loosen the hexagon socket screw with a hexagon wrench, and the second injection needle 35 can be easily removed from the first engaging groove 312.

[0076] It should be noted that the tail of the second injection needle 35 is connected to a liquid inlet tube, which is used to provide injection liquid to the second injection needle 35. The liquid inlet tube is usually made of a flexible material. One end of the liquid inlet tube is connected to an external liquid storage container (such as a liquid storage bottle or liquid storage tank), and the other end is fixed to the tail of the second injection needle 35 through a suitable connection method.

[0077] Furthermore, if Figure 10 As shown, the poultry wing membrane injection device also includes a shielding protective member 34, which is rotatably arranged with the second injection fixing seat 31, and the shielding protective member 34 is provided with a shielding cavity that can cover the needle tip of the second injection needle 35.

[0078] In actual use, when the poultry wing membrane seeding device is in an idle state or needs to be transported or stored, the operator manually rotates the shielding protective part 34 around the rotating axis so that the shielding cavity accurately covers the needle tip of the second injection needle 35, avoiding collision and friction between the second injection needle 35 and external objects, and preventing dust and debris from adhering to the second injection needle 35; when the poultry wing membrane seeding operation is required, the shielding protective part 34 is rotated to one side to fully expose the second injection needle 35 for normal seeding operation.

[0079] In one embodiment, if Figure 12 As shown, a connecting block 313 is extended from one side of the second injection fixing seat 31 , and a first connecting hole 3131 is defined in the connecting block 313 .

[0080] Specifically, the connecting block 313 and the second injection fixing seat 31 may be manufactured in an integrally formed manner to enhance structural strength and stability.

[0081] The location and number of the first connection holes 3131 can also be adjusted based on actual conditions. For example, a single first connection hole 3131 can be positioned at the center of the connection block 313 for single-point connection scenarios. Alternatively, multiple first connection holes 3131 can be symmetrically distributed across the connection block 313 to achieve a more stable multi-point connection, suitable for connection scenarios that require withstanding significant external forces.

[0082] In practical applications, when the poultry wing membrane injection device needs to be installed on the poultry neck subcutaneous injection device 2, the connecting block 313 is connected to the first injection fixing seat 21 of the poultry neck subcutaneous injection device 2 by bolts.

[0083] like Figure 14-17As shown, the poultry eye drop immunization device 4 can be used in scenarios where poultry eye drops or nasal drops require drop immunization. Specifically, the poultry eye drop immunization device 4 includes a drop fixing seat 41 and a drop needle 42, a third sensing element 43 and a third proximity sensor 44 provided on the drop fixing seat 41. The third sensing element 43 is movably arranged up and down relative to the drop fixing seat 41. The drop needle 42 is arranged vertically, and the liquid outlet of the drop needle 42 is vertically downward, which is used to store and drip out the vaccine. In actual use, the drop needle 42 is connected to an external vaccine storage container, and the vaccine is transported to the drop needle 42 through a pipeline. When the dripping conditions are met, the vaccine drips out from the liquid outlet of the drop needle 42. The third sensing element 43 has at least a first state in which it senses the third proximity sensor 44 and a second state in which it does not sense the third proximity sensor 44. When the third sensing element 43 switches from the second state to the first state, the dripping needle 42 performs a quantitative injection. After the injection is completed, the third sensing element 43 returns to its original state and waits for the next injection trigger. When the third sensing element 43 is in the first state, that is, when the third sensing element 43 moves upward and senses the third proximity sensor 44, the third proximity sensor 44 is triggered, and the dripping needle 42 performs a dripping operation, and the vaccine drips from the dripping needle 42 into the poultry's eyes.

[0084] Through the up and down movement of the third sensing element 43 relative to the drip holder 41, and the cooperation between the third sensing element 43 and the third proximity sensor 44, precise control of dripping is achieved according to whether the poultry is in place. Compared with traditional timing control methods, this avoids the waste of vaccines caused by blind dripping, while ensuring that each poultry can accurately obtain the vaccine, thereby improving the immunization effect. The design of the third sensing element 43 enables the dripping operation to quickly respond to changes in the position of the poultry, without the need for complicated operating procedures. In large-scale poultry farming scenarios, this device can greatly improve the efficiency of eye drop immunization and effectively reduce the intensity of manual labor.

[0085] In one embodiment, if Figure 17 As shown, the third sensing element 43 includes a sensing plate 431 and two connecting vertical plates 432 arranged on the left and right sides of the sensing plate 431. The third proximity sensor 44 is located above the sensing plate 431. The connecting vertical plates 432 are movably connected to the drip fixing seat 41.

[0086] Specifically, the sensing plate 431 can be designed as a rectangular flat plate, whose width is slightly larger than the lateral dimension of the third proximity sensor 44, and the length is set according to the comfort of the user's manual operation. The surface can be provided with an anti-slip texture to facilitate the user to push.

[0087] The third proximity sensor 44 is located above the sensing plate 431. When it is necessary to perform eye drops for immunization on poultry, the user pushes the sensing plate 431 upward with his hand, so that the sensing plate 431 and the third proximity sensor 44 form a sensing state, thereby triggering the dripping operation. In order to ensure the accuracy and reliability of the trigger, the sensing parts corresponding to the sensing plate 431 and the third proximity sensor 44 can be specially processed. For example, a raised triggering portion is provided on the upper surface of the sensing plate 431. The triggering portion is made of a material with moderate hardness and wear resistance, such as rubber or plastic, and its shape matches the sensed surface of the third proximity sensor 44. When the user pushes the sensing plate 431, the triggering portion is closer to the sensed surface of the third proximity sensor 44, thereby improving the sensitivity of the sensing.

[0088] In one embodiment, a limiting groove 411 is provided through the drip fixing seat 41 along its left and right directions, and the length direction of the limiting groove 411 extends in the upward and downward directions. A connecting rod 45 is passed through the limiting groove 411, and the connecting rod 45 has the freedom of movement in at least the upward and downward directions in the limiting groove 411. The two ends of the connecting rod 45 are respectively connected to the two connecting vertical plates 432.

[0089] Specifically, the length direction of the limiting groove 411 extends in the up and down direction, and its shape can be a rectangular groove, a T-shaped groove, etc. The width design of the limiting groove 411 needs to take into account the diameter of the connecting rod 45 to ensure that the connecting rod 45 can move freely up and down in the limiting groove 411, while limiting the movement of the connecting rod 45 in the horizontal direction, ensuring the stability and accuracy of the movement of the third sensing member 43.

[0090] The connecting rod 45 serves as a component connecting the third sensing element 43 and the drip holder 41, and its two ends are respectively connected to the two connecting vertical plates 432 of the third sensing element 43. The length of the connecting rod 45 is designed according to the size of the third sensing element 43 and the position of the limiting groove 411 to ensure that both ends can be accurately connected to the connecting vertical plates 432 and will not become loose or stuck when moving within the limiting groove 411. The connection method between the connecting rod 45 and the connecting vertical plates 432 can be welding, threaded connection, etc. Taking threaded connection as an example, a threaded hole matching the connecting rod 45 is provided on the connecting vertical plate 432, and the end of the connecting rod 45 is processed with an external thread. By screwing the connecting rod 45 into the threaded hole, a secure connection between the two is achieved.

[0091] When the user pushes the sensing plate 431 upward to perform a dripping operation, the sensing plate 431 drives the connecting rod 45 upward within the limiting groove 411 via the connecting vertical plate 432. Because the limiting groove 411 limits the connecting rod 45, the connecting rod 45 can only move in the up-and-down direction, thereby ensuring that the sensing plate 431 can accurately sense the third proximity sensor 44 and trigger the dripping needle 42 to perform the dripping operation.

[0092] The cooperation between the limiting groove 411 and the connecting rod 45 enables the third sensing element 43 to move up and down stably and precisely relative to the drip holder 41, ensuring the accuracy of the sensing between the third sensing element 43 and the third proximity sensor 44. This ensures that the drip needle 42 can drip at the correct time, avoiding dripping errors caused by deviations in the movement of the third sensing element 43 and improving the success rate of poultry eye drop immunization. Furthermore, this structural design is simple and reliable, facilitating fabrication and assembly, and reducing the production cost of the device.

[0093] In one embodiment, if Figure 16 and Figure 17 As shown, a second elastic return member is provided between the drip holder 41 and the third sensing member 43. The second elastic return member is a return spring. A spring groove 414 is provided at the bottom of the drip holder 41, and a positioning protrusion 4311 is provided on the sensing plate 431. The upper end of the return spring is embedded in the spring groove 414, and the lower end of the return spring is sleeved on the positioning protrusion 4311.

[0094] The shape of the spring groove 414 is adapted to the outer shape of the reset spring, and is a circular groove so that the reset spring can be smoothly embedded therein. At the same time, it can also play a certain limiting role on the reset spring to prevent it from deflecting during operation.

[0095] The positioning protrusion 4311 on the sensing plate 431 is designed to precisely mate with the lower end of the return spring. Positioning protrusion 4311 can be cylindrical, with a diameter slightly smaller than the inner diameter of the return spring. This allows the lower end of the return spring to fit snugly onto positioning protrusion 4311, preventing the return spring from separating from the sensing plate 431 during movement of the third sensing element 43. The height of positioning protrusion 4311 is designed based on the installation requirements of the return spring, ensuring stable installation of the return spring while preventing interference with the movement of the third sensing element 43.

[0096] When the user pushes the sensing plate 431 upward to perform a dripping operation, the sensing plate 431 drives the third sensing element 43 upward. The return spring is squeezed by the sensing plate 431 and gradually compressed, storing elastic potential energy in the return spring. When the dripping operation is completed and the user no longer applies force to the sensing plate 431, the return spring releases the stored elastic potential energy, generating an upward force that pushes the sensing plate 431 downward, returning the third sensing element 43 to its initial position.

[0097] Through the cooperation of the reset spring, the spring groove 414 of the drip fixing seat 41, and the positioning protrusion 4311 of the sensing plate 431, a reliable and stable automatic reset function of the third sensing element 43 is realized, ensuring that after each dripping operation, the third sensing element 43 can accurately return to the initial position, thereby ensuring the accuracy and consistency of subsequent dripping operations, and improving the work efficiency and success rate of poultry eye drop immunization.

[0098] In one embodiment, if Figure 16 As shown, the drip fixing seat 41 is provided with a mounting groove 412 , the notch of the mounting groove 412 extends to the bottom of the drip fixing seat 41 , and the third proximity sensor 44 is fixed in the mounting groove 412 , with the sensed surface of the third proximity sensor 44 facing downward.

[0099] The notch of the mounting groove 412 extends to the bottom of the drip holder 41. This facilitates installation and removal of the third proximity sensor 44 from the bottom and facilitates direct sensing between the sensing plate 431 and the sensing surface of the third proximity sensor 44. The third proximity sensor 44 can be fixed in the mounting groove 412 using screws, a snap-fit ​​connection, or an interference fit.

[0100] The sensing surface of the third proximity sensor 44 is positioned downward. When the user pushes the third sensing element 43 upward to initiate a dripping operation, the third sensing element 43 moves upward until it senses the sensing surface of the third proximity sensor 44. Once triggered, the third proximity sensor 44 sends an electrical signal to control the dripping needle 42 to continue the dripping operation. When the dripping operation is complete, the third sensing element 43, under the action of the second elastic return element, moves downward, separating from the sensing surface of the third proximity sensor 44. In this way, the operation of the dripping needle 42 is precisely controlled based on the sensing state of the third sensing element 43 and the third proximity sensor 44, ensuring that each dripping operation is executed accurately.

[0101] In one embodiment, if Figure 16 As shown, a mounting portion 413 is provided on the front side of the drip holder 41. The mounting portion 413 defines a second engaging groove 4131, into which the drip needle 42 is engaged. Second locking holes are provided on the left and right sides of the second engaging groove 4131, and second elastic locking blocks 41311 are provided in the second locking holes. When the second elastic locking blocks 41311 are tightened, the drip needle 42 is fastened in the second engaging groove 4131.

[0102] The second engaging groove 4131 defined in the mounting portion 413 is shaped to fit the engaging portion of the dripping needle 42. This groove is typically U-shaped or rectangular to accommodate the cylindrical dripping needle 42. The depth and width of the second engaging groove 4131 must be precisely designed to ensure that, once the dripping needle 42 is engaged, the liquid outlet remains vertically downward, meeting dripping operation requirements.

[0103] Second locking holes, located on either side of the second engaging groove 4131, are used to mount second elastic locking blocks 41311 to elastically engage the dripping needle 42. These second locking holes are threaded, with a diameter matching the threaded portion of the second elastic locking block 41311. In this embodiment, the second elastic locking block 41311 is in the form of a threaded tube with an elastic rubber screw mounted at the head. The length of the screw is selected based on the thickness of the second engaging groove 4131 and the material of the dripping needle 42, ensuring that the dripping needle 42 is securely and elastically engaged within the second engaging groove 4131 after installation.

[0104] When installing the dripping needle 42, first put the dripping needle 42 into the second clamping groove 4131, and then screw the second elastic locking block 41311 into the second locking hole. By twisting the second elastic locking block 41311, the end of the second elastic locking block 41311 is pressed against the dripping needle 42, thereby fastening the dripping needle 42 in the second clamping groove 4131; when the dripping needle 42 needs to be replaced, directly pull the second elastic locking block 41311 and overcome the elastic force of the elastic rubber head, so that the dripping needle 42 can be easily taken out for replacement.

[0105] In one embodiment, if Figure 17 As shown, the third sensing element 43 is provided with an avoidance notch 4312 at a portion corresponding to the needle tip of the dripping needle 42 .

[0106] In actual application, the avoidance gap 4312 is opened on the front side of the sensing plate 431. The center of the avoidance gap 4312 is aligned with the central axis of the vertical downward dripping of the dripping needle 42 to ensure that the needle tip of the dripping needle 42 will not be blocked by the third sensing component 43 during the entire working process. The avoidance gap 4312 can be designed as a semicircular, U-shaped or arc-shaped groove to adapt to the contour of the needle.

[0107] During the operation of the poultry eye drop immunization device 4, when the user pushes the third sensing element 43 upward to perform the dripping operation, the third sensing element 43 moves upward. Due to the presence of the avoidance gap 4312, the liquid dripping from the needle tip of the dripping needle 42 can smoothly pass through the avoidance gap 4312 and reach the eyes of the poultry.

[0108] In one embodiment, if Figure 16 As shown, a fixing plate 415 is provided on the top of the drip fixing seat 41 , and a second connecting hole 4151 is provided on the fixing plate 415 .

[0109] The fixing plate 415 is a rectangular plate structure, and its length and width must ensure that it can stably support the drip fixing seat 41 and related components, while being convenient for connection with external structures.

[0110] The number, position and shape of the second connection holes 4151 formed on the fixing plate 415 are designed according to the actual installation method and the type of external connection parts.

[0111] During actual installation, if a bolt connection is used, the bolt is inserted through the second connection hole 4151 and tightened with a nut on the external device or bracket to securely mount the drip holder 41 in the desired location. If a screw is used for direct mounting, the screw is screwed into a pre-threaded hole on the external device or bracket. The connection achieved through the second connection hole 4151 allows the drip holder 41 to be tightly coupled to the external structure, ensuring that the device does not shake or shift during poultry eye drop immunization.

[0112] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
