Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an auxiliary needle insertion device and a rotary vaccine injection machine. Background Technology

[0002] In existing poultry vaccination techniques, horizontal syringes are commonly used. This technique has a specific groove and a corresponding needle. Operators need to manually grasp the poultry's neck and squeeze it into the groove to form a bulge so that the needle can be accurately inserted into the bulge for vaccination. However, this method is inefficient. The process of manually squeezing the poultry's neck to form a bulge is time-consuming and laborious, especially in large-scale farming environments, requiring a large amount of manpower to complete the vaccination work, which greatly limits the injection efficiency.

[0003] Meanwhile, because operators need to squeeze poultry into the groove, improper operation can easily result in the moving needle pricking the operator's hand. Such injuries require serious attention. For example, when injecting poultry with oil-based vaccines, a minor prick may cause localized numbness in the hand, while a severe prick may require surgery to remove residual vaccine liquid, posing a threat to the operator's health. Therefore, there is an urgent need for an automated device that can improve vaccine injection efficiency and safety. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] This invention discloses an auxiliary needle insertion device, which aims to solve the problems of time-consuming, labor-intensive, and low-safety artificial vaccine injection for poultry in the prior art.

[0006] (2) Technical solution

[0007] This invention discloses an auxiliary needle insertion device, comprising a gripper mechanism, an injection mechanism, and a frame. The gripper mechanism is mounted on the frame, and the injection mechanism is movably connected to the frame. The gripper mechanism includes a symmetrically arranged left arm and a right arm that can open and close to each other. The left arm and the right arm are provided with a first gripping part and a second gripping part. Symmetrically arranged concave arc surfaces one and two are provided on opposite surfaces of the first and second gripping parts, forming an injection area. The injection mechanism includes a needle, and the needle... The injection areas are coaxially corresponding; at least one of the clamping parts one and two is provided with a protrusion. When the left and right arms are clamped together, an isolation zone is formed between the protrusions to isolate the muscle from the injection area, so as to completely isolate the subcutaneous tissue from the muscle and cervical spine; wherein, before the injection mechanism moves the needle into the injection area, the clamping mechanism rotates from the open state to the clamping state, so that the poultry skin is clamped in the injection area and forms a skin bulge that does not include the cervical spine and muscle, and the needle moves into the bulge to perform injection.

[0008] Furthermore, a fastener is fixed at the bottom of the frame, the left arm includes a first connecting part arranged horizontally, and the right arm includes a second connecting part arranged horizontally. Both the first connecting part and the second connecting part are provided with a through hole arranged coaxially, and the fastener passes through the through hole.

[0009] Furthermore, the fastener has a limiting step at its bottom, a first gasket is provided between the first connecting part and the bottom of the frame, a second gasket is provided between the second connecting part and the limiting step, and a first elastic element is pressed between the second gasket and the limiting step.

[0010] Furthermore, the peripheral wall of the injection mechanism is provided with a conical surface whose diameter increases sequentially from top to bottom. The opposing surfaces of the first connecting part and the second connecting part are respectively provided with a semi-circular surface one and a semi-circular surface two that abut against the conical surface. When the semi-circular surface one and the semi-circular surface two abut against the peripheral wall of the conical surface together, the gripper mechanism is in a clamping state; when the semi-circular surface one and the semi-circular surface two abut against the lower peripheral wall of the conical surface together, the gripper mechanism is in an open state.

[0011] Furthermore, a second elastic element is provided between the left arm and the right arm. One end of the second elastic element is fixedly connected to the left arm, and the other end is fixedly connected to the right arm, so that the gripper mechanism tends to maintain a clamping state.

[0012] Furthermore, it also includes a synchronization mechanism, which includes a symmetrically arranged left support member and a right support member. One end of the left support member is rotatably connected to the bottom of the first connecting part, and the other end is rotatably connected to the bottom of the frame. One end of the right support member is rotatably connected to the bottom of the second connecting part, and the other end is rotatably connected to the bottom of the frame.

[0013] Furthermore, the left support member is provided with a first gear tooth at one end rotatably connected to the frame, and the right support member is provided with a second gear tooth at one end rotatably connected to the frame, with the first gear tooth meshing with the second gear tooth.

[0014] Furthermore, the frame is provided with a connection hole, the injection mechanism passes through the connection hole, a first limiting ring is fixed in the connection hole, a second limiting ring is fixed on the outer peripheral wall of the injection mechanism and above the first limiting ring, and a third elastic element is elastically pressed between the first limiting ring and the second limiting ring.

[0015] Furthermore, the ends of the left arm and the right arm are each provided with symmetrically arranged "V" shaped cut surfaces.

[0016] The present invention also discloses a rotary vaccine injection machine, including a conveying mechanism, fixed positions, and an auxiliary needle insertion device. A plurality of the fixed positions are arranged on the conveying mechanism and convey the vaccines one by one toward the auxiliary needle insertion device. Poultry are placed in the fixed positions and the poultry in the fixed positions are conveyed to the auxiliary needle insertion device for vaccine injection.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The first concave arc surface and the second concave arc surface form an injection area, and the needle is coaxially and correspondingly arranged with the injection area; before the injection mechanism moves the needle into the injection area, the gripper mechanism rotates from the open state to the closed state under the action of the injection mechanism, so that the tissue other than the muscle tissue is clamped in the injection area, thereby improving the accuracy and stability of the injection.

[0019] 2. The injection mechanism and the gripper mechanism adopt a linkage design. When the injection mechanism is subjected to external force or other driving mechanism movement, the movement of the injection mechanism can automatically drive the gripper mechanism to clamp, making the clamping action of the gripper mechanism more automated and the matching error with the movement of the needle smaller.

[0020] 3. The auxiliary needle insertion device and rotary vaccine injection machine can perform batch automated vaccine injection for poultry, which significantly improves the efficiency of vaccination. Moreover, the machine-based vaccine injection can reduce the cost of manual injection and avoid the risk of operators being pricked by needles during the injection process.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1-13 As shown, the present invention discloses an auxiliary needle insertion device including a gripper mechanism 1, an injection mechanism 2, and a frame 3. The gripper mechanism 1 is disposed on the frame 3, and the injection mechanism 2 is movably connected to the frame 3. The gripper mechanism 1 includes a left arm 11 and a right arm 12 that are symmetrically arranged and can be opened and closed. The left arm 11 and the right arm 12 are provided with a clamping part 9 and a clamping part 10. The opposing surfaces of the clamping part 9 and the clamping part 10 are provided with a concave arc surface 111 and a concave arc surface 121 that are symmetrically arranged. The concave arc surface 111 and the concave arc surface 121 enclose an injection area 13. The injection mechanism 2 includes a needle 21, which is coaxially and correspondingly arranged with the injection area 13.

[0038] At least one of the clamping part 19 and clamping part 210 is provided with a protrusion 100. When the left arm 11 and the right arm 12 are clamped together, an isolation area 200 is formed between the protrusions to isolate the muscle from the injection area 13, so as to completely isolate the subcutaneous tissue from the muscle and cervical spine.

[0039] Before the injection mechanism 2 moves the needle 21 into the injection area 13, the gripper mechanism 1 rotates from the open state to the closed state, so that the poultry skin is clamped in the injection area 13 and forms a skin bulge that does not include the cervical vertebrae and muscles. The needle 21 moves into the bulge to perform injection.

[0040] It should be noted that the injection area for some vaccines, especially oil-based vaccines, is strictly limited. The skin structure of the poultry cervical spine consists of epidermis, subcutaneous tissue, muscle, and cervical spine from the outside in. Such vaccines can usually only be injected into the subcutaneous tissue area of ​​poultry. To further improve the success rate of vaccine injection, the gripper mechanism 1 pinches up the skin of the poultry to be injected to form a bulge. The height of the bulge is basically the same as the space of the injection area 13. The needle is inserted directly into the bulge. Since the gripping part 1 9 and the gripping part 2 10 are provided with protrusions 100, when the bulge is pinched up, an isolation area 200 is formed between the protrusions 100 to isolate the bulge from the muscle. At this time, the bulge area is all subcutaneous tissue. The protrusions 100 and the isolation area 200 can effectively physically isolate the subcutaneous tissue from the muscle or cervical spine, completely avoiding the risk of the needle 21 entering the muscle or cervical spine, thereby improving the accuracy and stability of the injection.

[0041] It should be noted that the isolation zone 200 is not directly formed by the protrusion 100, but is formed by the skin when the protrusion 100 clamps the skin and the skin is squeezed by the protrusion 100.

[0042] Specifically, when the injection mechanism 2 is not acted upon by an external force or driving mechanism, it does not move relative to the frame 3. At this time, the gripper mechanism 1 is in an open state to allow the poultry to be injected to be placed into or removed from its grasping range. In the open state, the opening angle between the left arm 11 and the right arm 12 of the gripper mechanism 1 is usually at its maximum to ensure sufficient space to hold the poultry to be injected. At this time, the needle 21 is furthest from the injection area 13. When the injection mechanism 2 is acted upon by an external force or driving mechanism, it descends, and the injection... Before the needle 21 is moved to the injection area 13 by the mechanism 2, the gripper mechanism 1 rotates from the open state to the clamping state under the action of the injection mechanism 2. At this time, the clamping state means that the left arm 11 and the right arm 12 of the gripper mechanism 1 are close to or in contact with each other, so as to grasp or clamp the poultry to be injected and pinch its skin to a certain degree of bulge, so as to separate the subcutaneous tissue of the poultry epidermis from the muscle or cervical spine. In the clamping state, the angle between the left arm 11 and the right arm 12 of the gripper mechanism 1 is small, so as to firmly grasp the neck of the poultry.

[0043] like Figure 4As shown, a fastener 31 is fixed to the bottom of the frame 3. The left arm 11 includes a first connecting part 112 arranged laterally, and the right arm 12 includes a second connecting part 122 arranged laterally. Both the first connecting part 112 and the second connecting part 122 are provided with coaxially arranged through holes 14, and the fastener 31 passes through the through holes 14. During installation, the design of the first connecting part 112 and the second connecting part 122 allows the left arm 11 and the right arm 12 to move relative to the frame 3 or be fixed in a specific position. The coaxial arrangement of the through holes 14 ensures the alignment accuracy of the first connecting part 112 and the second connecting part 122 during connection, thereby ensuring the symmetry and balance of the entire structure. At the same time, the first connecting part 112 and the second connecting part 122 can also rotate relative to each other to ensure the stability of the structure and the reliability of operation.

[0044] Furthermore, the fastener 31 can be a bolt or a screw. By setting the fastener 31, the installation structure of the left arm 11, the right arm 12 and the frame 3 is simplified, effectively improving the efficiency and convenience of installation, maintenance and replacement of the left arm 11 and the right arm 12.

[0045] Preferably, the fastener 31 is connected to the through hole 14 by a thread to facilitate the installation and removal of the fastener 31, while ensuring the connection stability between the fastener 31 and the frame 3.

[0046] Specifically, the fastener 31 has a limiting step 311 at its bottom, a first washer 312 is provided between the first connecting part 112 and the bottom of the frame 3, and a second washer 313 is provided between the second connecting part 122 and the limiting step 311. In use, the first washer 312 and the second washer 313 reduce friction, improve service life, and prevent the fastener 31 from loosening when the first connecting part 112 and the second connecting part 122 rotate.

[0047] Furthermore, in order to improve the rotational flexibility of the first connecting part 112 and the second connecting part 122, a first elastic element 314 is also provided between the second gasket 313 and the limiting step 311; the first elastic element 314 may be a spring or an elastic rubber material, which is designed to provide the necessary preload to keep the gripper mechanism 1 more flexible and reliable in switching between the clamping state and the opening state, while absorbing the impact and vibration generated during operation.

[0048] like Figure 5 As shown, the peripheral wall of the injection mechanism 2 is provided with a conical surface 22 whose diameter increases from top to bottom. The diameter of the conical surface 22 increases from top to bottom, forming a smooth transition surface. This design not only ensures the smoothness of the gripper mechanism 1 in the clamping and opening process, but also helps to reduce friction and wear during operation.

[0049] Furthermore, the first connecting portion 112 and the second connecting portion 122 are respectively provided with a semi-circular surface 113 and a semi-circular surface 123 on their opposite surfaces, which abut against the conical surface 22. When the semi-circular surface 113 and the semi-circular surface 123 abut against the upper wall of the conical surface 22, the gripper mechanism 1 is in a clamping state, at which time the left arm 11 and the right arm 12 are close to each other, achieving a firm grip on the target poultry. Conversely, when the semi-circular surface 113 and the semi-circular surface 123 abut against the lower wall of the conical surface 22, the gripper mechanism 1 is switched to an open state, at which time the left arm 11 and the right arm 12 are far apart, allowing the target poultry to be put in or taken out.

[0050] like Figure 6 As shown, a second elastic element 15 is provided between the left arm 11 and the right arm 12. One end of the second elastic element 15 is fixedly connected to the left arm 11, and the other end is fixedly connected to the right arm 12, so that the gripper mechanism 1 tends to maintain a clamping state. In the design of the gripper mechanism 1, the second elastic element 15 can be a spring. The introduction of the second elastic element 15 is to provide a continuous clamping tendency force between the left arm 11 and the right arm 12. This force can prevent the gripper mechanism 1 from accidentally opening due to vibration or other external forces during the clamping process. This design ensures that the gripper mechanism 1 can maintain its clamping state even in the presence of external loads or interference, thereby improving the stability and reliability of clamping.

[0051] like Figure 13 As shown, the present invention also provides a second embodiment, wherein the peripheral wall of the injection mechanism 2 is provided with a conical surface 22 whose diameter decreases from top to bottom, forming a smooth transition surface. The opposing surfaces of the first connecting part 112 and the second connecting part 122 are respectively provided with a semi-circular surface 113 and a semi-circular surface 123 that abut against the conical surface 22. When the semi-circular surface 113 and the semi-circular surface 123 abut against the peripheral wall of the conical surface 22, the gripper mechanism 1 is in an open state, with the left arm 11 and the right arm 12 moving away from each other, allowing the target poultry to be placed in or removed. Conversely, when the semi-circular surface 113 and the semi-circular surface 123 abut against the lower peripheral wall of the conical surface 22, the gripper mechanism 1 is switched to a clamping state, with the left arm 11 and the right arm 12 moving closer together, achieving a firm grip on the target poultry.

[0052] It should be noted that in the first embodiment, the cone surface 22 with the diameter increasing from top to bottom is moved downward so that the semi-circular surface 113 and the semi-circular surface 123 abut against the upper wall of the cone surface 22, thereby causing the left arm 11 and the right arm 12 to move closer to each other at the same time, causing the clamping part 19 and the clamping part 20 to be in a clamping state.

[0053] Conversely, in the second embodiment, the cone surface 22, whose diameter decreases from top to bottom, is moved downward so that the first semi-circular surface 113 and the second semi-circular surface 123 abut against the upper wall of the cone surface 22. This causes the left arm 11 and the right arm 12 to open at the end near the cone surface 22, and the end away from the cone surface 22 to drive the clamping part 9 and the clamping part 10 to move closer to each other and form a clamping state.

[0054] Therefore, the purpose of the above two embodiments is to enable the injection mechanism 2 to move downward so as to drive the gripper mechanism 1 to perform a clamping effect. So, under the same effect, the technical solutions in which the injection mechanism 2 moves upward or downward so as to drive the gripper mechanism 1 to open or close are all within the protection scope of this application.

[0055] like Figure 8-9 As shown, the auxiliary needle-feeding mechanism also includes a synchronization mechanism 4. The synchronization mechanism 4 includes a symmetrically arranged left support member 41 and a right support member 42. The left support member 41 has a fixing hole 161, and the right support member 42 has a fixing hole 162. The first connecting part 112 has a limiting hole 114 coaxially corresponding to the fixing hole 161, and the second connecting part 122 has a limiting hole 124 coaxially corresponding to the fixing hole 162. The first connecting part 112 and the second connecting part 122 include locking members 7. The locking members 7 are inserted into the fixing hole 161 and the limiting hole 114, and the locking members 7 are inserted into the fixing hole 162 and the limiting hole 124. The left support... One end of the left support member 41 is rotatably connected to the bottom of the first connecting part 112, and one end of the right support member 42 is rotatably connected to the bottom of the second connecting part 122. The left support member 41 is provided with a positioning hole 413, and the right support member 42 is provided with a positioning hole 423. A shaft pin 19 is inserted into both the positioning hole 413 and the positioning hole 423. The first connecting part 112 and the second connecting part 122 are both provided with coaxially corresponding clearance holes 18. The diameter of the clearance hole 18 is larger than the diameter of the shaft pin 19. The shaft pin 19 does not interfere with the movement of the left arm 11 and the right arm 12. The other end of the left support member 41 is rotatably connected to the bottom of the frame 3. The other end of the right support member 42 is rotatably connected to the bottom of the frame 3.

[0056] Furthermore, such as Figure 9As shown, the left support member 41 is rotatably connected to the frame 3 at one end and is provided with a first gear tooth 411. The right support member 42 is rotatably connected to the frame 3 at one end and is provided with a second gear tooth 421. The first gear tooth 411 meshes with the second gear tooth 421. This design enables the left arm 11 and the right arm 12 to move precisely and synchronously relative to the frame 3, so as to realize the synchronous clamping or opening function of the left arm 11 and the right arm 12.

[0057] like Figure 10 As shown, the frame 3 has a connecting hole 32, and the injection mechanism 2 passes through the connecting hole 32 to ensure the correct positioning of the injection mechanism 2 within the connecting hole 32 and restrict its axial movement. A first limiting ring 321 is fixedly installed in the connecting hole 32, and a second limiting ring 322 is fixedly installed on the outer peripheral wall of the injection mechanism 2 above the first limiting ring 321. A third elastic element 33 is elastically pressed between the first limiting ring 321 and the second limiting ring 322. The third elastic element 33 can be a spring. The third elastic element 33 provides a restoring force for the injection mechanism 2, which helps to maintain the position of the injection mechanism 2 during operation and to move upward and reset without being subjected to external force or other driving mechanisms.

[0058] Preferably, such as Figure 1 As shown, the ends of the left arm 11 and the right arm 12 are provided with symmetrically arranged "V" shaped cut surfaces. When the gripper mechanism 1 is in the clamping state, these "V" shaped cut surfaces correspond to each other and form a narrow groove. When the poultry skin being injected is clamped and raised, the design of the "V" shaped cut surfaces, which are adapted to the fluid design of the raised skin tissue surface, increases the comfort of the poultry being injected during the process of clamping the skin.

[0059] This invention discloses a rotary vaccine injection machine, such as... Figure 11-12 As shown, the device includes a conveying mechanism 5, fixed positions 6, and the auxiliary needle insertion device. The conveying mechanism 5 includes a driving mechanism and a chain 51. The driving mechanism provides power for the transmission of the chain 51, enabling the chain 51 to perform continuous transmission. The chain 51 is also provided with a number of spaced fixed positions 6. During operation, as the chain 51 is driven, the number of fixed positions 6 are conveyed one by one toward the auxiliary needle insertion device. Poultry is placed in the fixed positions 6, and the poultry in the fixed positions 6 is conveyed to the auxiliary needle insertion device for injection.

[0060] In use, the design of the fixing position 6 is intended to provide stability support and fixation for poultry. The setting of the fixing position 6 not only improves the accuracy of needle insertion and saves the labor cost of manually placing poultry on the needle 21 for injection, but also improves the production efficiency of the entire rotary equipment, ensuring that needle insertion and injection can be performed automatically when each fixing position 6 reaches the predetermined position. Therefore, this automated rotary needle insertion method not only improves production efficiency and optimizes the operator's operation steps, but also effectively improves the operator's operation safety.

[0061] The working principle of the present invention will be explained in detail below;

[0062] The poultry to be injected is fixed in the fixed position 6. The fixed position 6 is conveyed one by one towards the auxiliary needle device by the transmission of the chain 51. When the fixed position 6 reaches the position of the auxiliary needle device, the injection mechanism 2 moves down and drives the gripper mechanism 1 to rotate from the open state to the clamping state. The gripper mechanism 1 pinches up a certain length of bulge on the skin of the poultry to be injected. When the needle 21 on the injection mechanism 2 moves into the injection area 13, the needle position is directly opposite the bulge, thereby effectively isolating the skin from the muscle or cervical spine, completely avoiding the risk of injecting into the muscle or cervical spine, and thus improving the accuracy and stability of the injection.

[0063] After injection, the injection mechanism 2 moves upward under the elastic force of the third elastic element 33, simultaneously driving the gripper mechanism 1 to rotate again and switch to the open state to release the poultry's skin. Then, the conveying mechanism 5 continues to transport the next fixed position 6 to the position of the auxiliary needle device. This process is repeated cyclically to achieve continuous automated injection operation on a rotary basis. The above-mentioned rotary working principle realizes the efficient operation of automated injection, ensuring accurate positioning and stable clamping during the injection process, as well as continuous transport and positioning of the poultry to be injected, greatly improving production efficiency, reducing labor costs, and making it suitable for large-scale production environments.

[0064] The innovation of this invention lies in the fact that the concave arc surface 111 and the concave arc surface 121 form an injection area 13, and the needle 21 is coaxially and correspondingly arranged with the injection area 13. Before the injection mechanism 2 moves the needle 21 into the injection area 13, the gripper mechanism 1 rotates from an open state to a closed state under the action of the injection mechanism 2, so that the tissue other than the muscle tissue is clamped in the injection area 13, thereby improving the accuracy and stability of the injection.

[0065] The injection mechanism 2 and the gripper mechanism 1 adopt a linkage design. When the injection mechanism 2 is subjected to external force or other driving mechanism movement, the movement of the injection mechanism 2 can automatically drive the gripper mechanism 1 to clamp, making the clamping action of the gripper mechanism 1 more automated and the coordination error with the movement of the needle 21 smaller.

[0066] The auxiliary needle insertion device and rotary vaccine injection machine can perform batch automated vaccine injection for poultry, which significantly improves the efficiency of vaccination. Furthermore, machine-based vaccine injection can reduce the cost of manual injection and avoid the risk of operators being pricked by the needle 21 during the injection process.

[0067] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0068] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
