Abstract
Description
Technical Field
[0001] This utility model relates to the field of poultry injection technology, and in particular to an injection device and poultry processing equipment. Background Technology
[0002] In related technologies, diseases are treated and immunized by injecting drugs into poultry. Depending on the disease, immunization, and drug type, subcutaneous injection or intramuscular injection can be selected. Intramuscular injection requires a higher needle insertion depth and carries the risk of puncturing internal organs and damaging blood vessels. Subcutaneous injection is usually performed under the skin of the neck, with the injection site parallel to the scalp of the poultry's head. It is greatly affected by the location of blood vessels, which is not conducive to injection. When the poultry is standing after the injection, the injection site is at the lowest point of the neck bend, which affects the drug's effectiveness. Utility Model Content

Detailed Implementation
[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0035] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0036] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0038] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0039] In related technologies, subcutaneous injection into the neck of poultry is used to treat diseased birds or to provide immunization. However, the injection site is parallel to the bony line of the bird's head, which is greatly affected by the blood vessels in the neck and is prone to puncturing blood vessels. In addition, some birds carry cysts, which can easily rupture during injection. Furthermore, usually when birds are injected, their necks are extended under restraint. After the injection, when the birds are standing, their necks are bent in a "V" shape, and the subcutaneous injection site is at the lowest point of the neck bend, which is not conducive to the drug's effectiveness.
[0040] For ease of understanding, the concepts or features involved in this application are explained as follows:
[0041] The terms "front" and "back" used in this application refer to the injection state of poultry, with the direction of the poultry's head being "front" and the direction of the poultry's head being "back". "Vertical" and "horizontal" are not strictly vertical or horizontal planes. Considering the influence of processing and assembly factors, a certain degree of angular deviation is allowed.
[0042] Reference Figure 1 and Figure 2 This utility model provides an injection device, including a restraint mechanism 100 and an injection structure 200. The injection structure 200 is used to inject poultry, and the restraint mechanism 100 is used to restrain poultry, restrain the stress response of poultry during the injection process, and avoid injection deviation caused by poultry stress, which could cause damage to poultry. The restraint mechanism 100 includes a first restraint structure 110 and a second restraint structure 120. The first restraint structure 110 is used to hang the head of the poultry in a vertical direction. The restraint mechanism 100 has a restraint state for the poultry. When the restraint mechanism 100 is in the restraint state, the injection structure 200 injects the poultry. At this time, the first restraint structure 110 limits the head of the poultry in a first direction, and the second restraint structure 120 presses against the rear side of the poultry in a second direction. The first direction and the second direction are perpendicular to the vertical direction. The poultry can be restrained by the restraint mechanism 100 from different directions and is stably in a restrained state, which facilitates the injection device to inject the poultry.
[0043] The injection structure 200 has an injection needle 210 for injecting drugs into the neck of poultry along the injection direction, and the injection direction is inclined relative to the second direction in the first direction. The injection needle 210 performs subcutaneous injection into the neck of poultry in an inclined state, and the insertion direction of the injection needle 210 avoids the direction of the blood vessels in the neck of poultry, thus reducing the influence of the neck blood vessels on the injection position during the injection process. In addition, since the second restraint structure 120 restrains the rear side of poultry along the second direction, and the injection direction is inclined relative to the second direction, the injection position of the injection needle 210 is located on the side of the neck of poultry. The side-down insertion method requires less precision in the insertion depth of the injection needle 210 compared to the conventional vertical insertion method. Furthermore, when the poultry is in a standing position, the injection position is located on the side of the neck bend, which has less impact on the efficacy of the drug and can improve the injection effect.
[0044] Understandably, the second restraint structure 120 presses down on the rear of the bird along the second direction, which is parallel to the front-back direction. After the bird's head is placed on the first restraint structure 110, it is supported by the first restraint structure 110. Under the influence of gravity, the bird's height in the vertical direction is restricted. Simultaneously, the first restraint structure 110 restricts the bird's head along the first direction, and the second restraint structure 120 presses down on the rear of the bird along the second direction, restricting the front of the bird. Through the cooperation of the first restraint structure 110 and the second restraint structure 120, the bird is simultaneously restricted in the first direction, the second direction, and the vertical direction, keeping the bird stably restrained and reducing the impact of bird stress on the injection.
[0045] Furthermore, in the first direction, the angle between the injection direction and the vertical direction is α, where 5°≤α≤35°, so that the injection needle 210 is injected into the neck of the bird in an inclined state. On the one hand, this avoids the injection direction from being too upright, which would cause the injection needle 210 to be affected by the blood vessels in the neck. On the other hand, it reduces the range of motion of the injection needle 210 in the horizontal plane, and avoids the injection needle 210 from tilting at too large an angle, which would affect the accuracy of the insertion depth.
[0046] like Figure 3The first restraining structure 110 includes a mounting part 111, a first restraining part 112 and a second restraining part 113. The first restraining part 112 and the second restraining part 113 are connected to the same side of the mounting part 111 and are distributed at intervals along a first direction. The first restraining part 112 and the second restraining part 113 define a restraining groove 114 for receiving the head of a poultry. The bird's head is placed between the first restraining part 112 and the second restraining part 113, and is supported by the first restraining part 112 and the second restraining part 113 in the first direction. The bird's head is in contact with the top of the mounting part 111 and is supported by the top of the mounting part 111. A part of the bird's head or the bird's neck is accommodated in the restraining groove 114, which runs through the front and back direction. The bird's head can pass through the restraining groove 114 and extend to the front side of the first restraining structure 110, while the other parts are left at the rear side of the first restraining structure 110. Thus, the second restraining structure 120 can press the bird forward from the rear side of the first restraining structure 110, so that the bird is clamped between the first restraining structure 110 and the second restraining structure 120 in the second direction and is in a stable holding state.
[0047] Reference Figure 4 The restraining mechanism 100 also includes a first driving member 130, which is connected to the first restraining structure 110 and drives the first restraining structure 110 to rotate. Specifically, the plane containing the second direction and the vertical direction is defined as the vertical plane. The first restraining structure 110 can rotate in the vertical plane. Driven by the first driving member 130, the first restraining structure 110 can rotate from a horizontal state to a vertical state. When the first restraining structure 110 is in a horizontal state, the restraining groove 114 passes through in the vertical direction, and one end of the restraining groove 114 forms an opening 115. The poultry head can be hung in the restraining groove 114 through the opening 115. During the process of the first restraining structure 110 rotating from a horizontal state to a vertical state, the poultry head is always supported by the top of the mounting part 111 and stably transitions to the vertical state. At this time, the restraining mechanism 100 is in a restraining state. By setting up the installation part 111, the first restraint part 112 and the second restraint part 113, poultry can maintain a stable position in different states and smoothly switch between different states.
[0048] The second restraint structure 120 includes a pressing part 121 and a guide part 122. The guide part 122 is installed on the pressing part 121. The pressing part 121 is used to press the rear side of the poultry. The injection needle 210 is slidably connected to the guide part 122 along the injection direction. The guide part 122 guides the movement of the injection needle 210, so that the injection needle 210 can always move back and forth along the injection direction, avoiding deviation or bending of the injection needle 210 during movement. While the pressing part 121 in the second restraint structure 120 presses the rear side of the poultry, the guide part 122 is in a ready-to-injection state. Since the injection needle 210 is connected to the guide part 122, the pressing position of the pressing part 121 and the injection position of the injection needle 210 can be pre-positioned simultaneously.
[0049] The restraining mechanism 100 also includes a second driving member 140, which is connected to the second restraining mechanism 100 and is used to drive the second restraining structure 120 to flip. The plane containing the second direction and the vertical direction is defined as the vertical plane. The second restraining structure 120 flips within the vertical plane. Driven by the second driving member 140, the second restraining structure 120 can flip from a horizontal state to a vertical state. When the second restraining structure 120 is in a horizontal state, it avoids the flipping of the first restraining structure 110, allowing the first restraining structure 110 to flip upwards from a horizontal state to a vertical state, thus restraining the bird's head. After the first restraining structure 110 flips to a vertical state, the second restraining mechanism 100 flips downwards from a horizontal state to a vertical state. At this time, the pressing part 121 presses forward on the bird from the rear side of the first restraining structure 110, restraining the bird in the second direction. Understandably, when both the first restraining structure 110 and the second restraining structure 120 are in a vertical state, the restraining mechanism 100 is in a restraining state. At this time, the injection structure 200 injects the poultry. After the injection is completed, the second driving member 140 drives the second restraining structure 120 to flip upward, avoiding the flipping of the first restraining structure 110. After the second restraining structure 120 flips to a horizontal state, the first restraining structure 110 flips downward from a vertical state to a horizontal state.
[0050] It should be noted that, since the pressing part 121 is connected to the guide part 122 and the injection needle 210 is slidably connected to the guide part 122, when the second driving member 140 drives the second restraining structure 120 to flip, the injection needle 210 flips synchronously with the second restraining structure 120. Thus, when the second restraining structure 120 switches to a vertical state by flipping and restrains poultry, the injection needle 210 switches to the injection position synchronously, which can perform the injection action more quickly without the need for additional positioning of the injection position of the injection needle 210, thereby improving the injection efficiency of the injection device.
[0051] Both the first driving member 130 and the second driving member 140 can be selected as power components capable of outputting rotational motion, such as rotary motors, electric motors, etc. In some embodiments, the restraining mechanism 100 includes a plurality of first restraining structures 110 and second restraining structures 120. The restraining mechanism 100 also includes a first connecting portion 150 and a second connecting portion 160. The plurality of first restraining structures 110 are installed on the first connecting portion 150 and arranged at intervals, and the plurality of second restraining structures 120 are installed on the second connecting portion 160 and arranged at intervals. The number and position of the first restraining structures 110 and the second restraining structures 120 are matched so that each poultry can be restrained by the combined restraining effect of the first restraining structures 110 and the second restraining structures 120 when injected. It is understood that by connecting the first driving member 130 to the first connecting portion 150, the plurality of first restraining structures 110 can share a power source for flipping; and by connecting the second driving member 140 to the second connecting portion 160, the plurality of second restraining structures 120 can share a power source for flipping. Both the first driving member 130 and the second driving member 140 can be connected to the first connecting part 150 or the second connecting part 160 through a transmission structure to change the transmission direction and adapt to the layout of the components. For example, the transmission structure can be set as a worm gear transmission mechanism, a bevel gear transmission mechanism, etc. Taking the connection between the first driving member 130 and the bevel gear rotation mechanism as an example, the first driving member 130 and the first connecting part 150 are connected through the bevel gear transmission mechanism. The first connecting part 150 passes through one of the bevel gears. The first driving member 130 is located in the middle of the first connecting part 150 and can transmit power to the two opposite directions of the first connecting part 150 at the same time.
[0052] In one embodiment, the guide portion 122 is movably connected to the pressing portion 121 and can move relative to the pressing portion 121 in the front-back direction to change the position of the guide portion 122 in the front-back direction, thereby adjusting the injection position of the injection needle 210 in the front-back direction, so that the injection device can be applied to injection of poultry at different times or of different types. The movable connection between the guide portion 122 and the pressing portion 121 is not limited to the following methods: for example, one of the guide portion 122 and the pressing portion 121 has a waist-shaped hole extending in the front-back direction; the guide portion 122 and the pressing portion 121 are threadedly connected; a threaded fastener passes through the waist-shaped hole and locks the guide portion 122 and the pressing portion 121; moving the position of the threaded fastener in the waist-shaped hole can change the relative position of the guide portion 122 and the pressing portion 121 in the front-back direction, thereby realizing the injection of the injection needle 210. The injection position can be adjusted; or, the guide part 122 and the pressing part 121 are arranged in the front-back direction, and multiple gaskets are provided between them. The guide part 122 and the pressing part 121 are threadedly connected, and threaded fasteners are passed through the guide part 122, the pressing part 121 and the gaskets, and the guide part 122 and the pressing part 121 are locked. The gaskets are clamped between the guide part 122 and the pressing part 121. Increasing or decreasing the number of gaskets can change the position of the guide part 122 in the front-back direction, thereby adjusting the injection position of the injection needle 210.
[0053] like Figure 5 and Figure 6 As shown, the injection structure also includes an injection rod 220 and a clamping part 230. An injection needle 210 is mounted on the clamping part 230, which is movably connected to the injection rod 220 along the injection direction. The injection rod 220 can move along the injection direction, causing the clamping part 230 to move synchronously. The injection needle 210 moves along the injection direction under the influence of the clamping part 230 to perform injection. Since the clamping part 230 can move relative to the injection rod 220 along the injection direction, and the injection needle 210 is mounted on the clamping part 230, changing the position of the clamping part 230 in the injection direction can adjust the height of the lower end of the injection needle 210, thereby changing the insertion depth of the injection needle 210 into the neck of the bird, making the injection device more convenient to use. Understandably, the movable connection between the clamping part 230 and the injection rod 220 is similar to the movable connection between the guide part 122 and the pressing part 121. That is, a waist-shaped hole extending along the injection direction can be provided on the clamping part 230 or the injection rod 220, or the clamping part 230 and the injection rod 220 can be arranged along the injection direction, and a gasket can be clamped between them, which can be achieved by increasing or decreasing the number of gaskets.
[0054] The restraining mechanism 100 also includes a fixing structure 240, which has a guide groove 241 extending along the injection direction. The injection rod 220 is slidably connected within the guide groove 241, which guides the sliding of the injection rod 220. A second restraining structure 120 is mounted on the fixing structure 240, and a second driving member 140 is connected to the fixing structure 240. The second driving member 140 drives the fixing structure 240 to reciprocate, thereby achieving the flipping of the second restraining structure 120. The injection structure also includes a third driving member 260 and an elastic member 250. The third driving member 260 is used to drive the injection rod 220 to move within the guide groove 241. The end of the injection rod 220 away from the injection needle 210 has a supporting portion 221. The two ends of the elastic member 250 are respectively connected to the supporting portion 221 and the fixing structure 240. During the injection process, the third driving member 260 presses down on the holding part 221 of the injection rod 220 along the injection direction, the injection rod 220 moves downward, and the elastic member 250 is compressed at the same time. The clamping part 230 moves with the movement of the injection rod 220 and simultaneously drives the injection needle 210 to move downward to realize the injection. After the injection is completed, the third driving member 260 removes the pressing force on the injection rod 220, the elastic force of the elastic member 250 is restored, the holding part 221 is pushed upward by the upward holding force of the elastic member 250, and at the same time the clamping part 230 drives the injection needle 210 to retract upward, and the injection needle 210 returns to the initial state.
[0055] It should be noted that, since the injection rod 220 is connected to the fixed structure 240, when the fixed structure 240 is driven to rotate by the second driving member 140, the injection rod 220 rotates synchronously with the fixed structure 240. In some embodiments, the third driving member 260 is always connected to the injection rod 220 and rotates synchronously with the injection rod 220. The third driving member 260 can be selected as a power component capable of outputting linear motion, such as a cylinder, an electric cylinder, or a linear motor. Alternatively, in other embodiments, the third drive member 260 and the injection rod 220 are configured to be relatively independent and separable from each other. The third drive member 260 does not need to rotate with the injection rod 220, which can reduce the load driven by the second drive member 140 and make the rotation of the second holding structure 120, injection needle 210, and injection rod 220 more stable. Specifically, the injection device also includes a base 300, and the third drive member 260 is mounted on the base 300. The output end 261 of the third drive member 260 can move relative to the supporting part 221. When the output end of the third drive member 260 extends, it can contact the supporting part 221 and push the supporting part 221 to move along the injection direction, so that the injection needle 210 performs the injection operation. After the injection is completed, the output end 261 of the third drive member 260 retracts and moves away from the injection rod 220. At this time, the output end 261 of the third drive member 260 and the supporting part 221 are separated from each other, so that the injection rod 220 can be rotated independently.
[0056] Specifically, the third drive component 260 is located above the injection rod 220, and the base 300 and the injection rod 220 have a certain gap in the front-to-back direction to ensure that the injection rod 220 will not collide with the third drive component 260 and the base 300 when it is flipped.
[0057] In one embodiment, the third driving element 260 is selected as an electromagnetic driving element, such as an electromagnet. This eliminates the need for numerous pneumatic and electric circuits, simplifying the structure of the injection device. Additionally, a heat dissipation structure 270 can be provided to cool the third driving element 260. The heat dissipation structure 270 is mounted on the base 300 and positioned opposite the third driving element 260. The heat dissipation structure 270 can be configured as a fan, heat sink fins, etc., to provide rapid heat dissipation and cooling for the third driving element 260.
[0058] Furthermore, the second restraining structure 120 is movably mounted on the fixed structure 240 and can move relative to the fixed structure 240 along the first and / or second directions to change the relative positions of the second restraining structure 120 and the fixed structure 240 in the first and / or second directions, so that the injection needle 210 can better cooperate with the guide portion 122. In a specific embodiment, the second restraining structure 120 is provided with a waist-shaped hole extending along the first direction, the second restraining structure 120 and the fixed structure 240 are arranged along the second direction, and a plurality of gaskets are provided between them. Threaded fasteners are inserted into the waist-shaped hole and into the gaskets and the fixed structure 240, locking the fixed structure 240 and the second restraining structure 120. By increasing or decreasing the number of gaskets, the relative positions of the second restraining structure 120 and the fixed structure 240 in the second direction can be changed. By changing the position of the threaded fasteners in the waist-shaped hole, the relative positions of the second restraining structure 120 and the fixed structure 240 in the first direction can be adjusted.
[0059] This utility model also provides a poultry processing device, including the aforementioned injection device and a beak trimming device 400.
