Description

Technical Field

[0001] This utility model relates to the field of poultry processing technology, and in particular to a restraint device and poultry processing equipment. Background Technology

[0002] During poultry farming, poultry undergo treatments such as beak trimming and vaccination. When these treatments are performed, poultry must be restrained manually or mechanically to prevent stress and defensive actions that could lead to treatment failure and ensure treatment quality. In some techniques, a fork is used to hold the poultry by its head and transport it. However, during transport, the fork changes direction as it moves with the conveyor belt, making it easy for the poultry's head to detach from the fork, resulting in restraint failure and affecting the normal processing of the poultry. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a restraint device that can effectively restrain poultry and allow for normal handling.

[0006] The first restraining mechanism includes a hanging fork and a first driving element. The hanging fork has a hanging groove, with one end of the groove wall forming a hanging part and the other end forming an open hanging opening. The hanging part is used to hang the head of a poultry. The hanging fork has a first state in which the hanging opening faces a first direction and a second state in which the hanging opening faces a second direction. The first driving element is connected to the hanging fork and drives the hanging fork to flip, so that the hanging fork reciprocates between the first state and the second state. In the flipping direction of the hanging fork, the angle between the first direction and the vertical plane is greater than the angle between the second direction and the vertical plane.

[0007] The second restraint mechanism includes a pressure plate and a second driving element. The second driving element is connected to the pressure plate and drives the pressure plate to flip so that when the fork is in the first state, the pressure plate avoids the fork and when the fork is in the second state, it presses down on the rear side of the poultry.

[0008] The restraining device according to the embodiments of the present utility model has at least the following beneficial effects:

[0009] The fork in the first restraint mechanism and the pressure plate in the second restraint mechanism simultaneously restrain the poultry. When the fork flips from the first state to the second state, the poultry's head is always supported by the hanging part and limited by the wall of the hanging slot under the action of gravity. In addition, the orientation of the hanging opening gradually changes from horizontal to vertical during this process. Under the action of gravity, the poultry's head cannot be removed from the hanging slot, thus achieving effective restraint of the poultry and reducing the impact of poultry stress on the treatment effect.

[0010] According to some embodiments of the present invention, the second restraining mechanism further includes a fixed wing, which is installed at one end of the pressure plate and can rotate with the pressure plate. The fixed wing has two opposing wing portions and is used to restrain the wings of poultry at the rear of the fork when the fork is in the second state.

[0011] According to some embodiments of the present invention, the fixed wing is movably mounted on the pressure plate.

[0012] According to some embodiments of the present invention, when the hanging fork is in the first state, it is perpendicular to the vertical plane, and when the hanging fork is in the second state, it is parallel to the vertical plane.

[0013] According to some embodiments of the present invention, the hanging slot has a first slot and a second slot that are interconnected. The first slot is located between the second slot and the hanging opening. The opening of the second slot is smaller than the opening of the first slot. Along the hanging direction from the bird's head toward the hanging slot, the opening of the first slot first increases and then decreases.

[0014] According to some embodiments of the present invention, the fork has a recessed limiting groove, and when the fork is in the second state, the limiting groove is located on the rear side of the fork.

[0015] According to some embodiments of the present invention, the restraining device further includes a base, the base including a base, a first moving part and a second moving part, the first restraining mechanism being installed on the first moving part, the second restraining mechanism being installed on the second moving part, and both the first moving part and the second moving part being movably connected to the base.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] Reference Figure 1 and Figure 2 This utility model provides a restraining device, including a first restraining mechanism 100 and a second restraining mechanism 200. The first restraining mechanism 100 includes a fork 110 and a first driving element 120. The fork 110 has a hanging groove 111, which can accommodate the head and neck of poultry. Figure 3 The wall of the hanging groove 111 at one end forms a hanging part 112, and the opposite end forms an open hanging opening 113. The hanging part 112 is used to hang the head of the poultry. During the poultry restraint process, the head of the poultry is placed into the hanging groove 111 through the hanging opening 113. After the head of the poultry comes into contact with the hanging part 112, the head of the poultry is supported by the hanging part 112 and hung on the hanging fork 110.

[0039] like Figure 2 The fork 110 has a first state and a second state. When the fork 110 is in the first state, poultry are hung on the fork 110. When the fork 110 is in the second state, the poultry are restrained and can be processed accordingly. Specifically, when the fork 110 is in the first state, the hanging opening 113 faces the first direction; when the fork 110 is in the second state, the hanging opening 113 faces the second direction. The first driving element 120 is connected to the fork 110 and can drive the fork 110 to rotate, so that the fork 110 reciprocates between the first state and the second state. In the rotation direction of the fork 110, the angle between the first direction and the vertical plane is greater than the angle between the second direction and the vertical plane, so that the fork 110 is closer to the horizontal plane in the first state and closer to the vertical plane in the second state. When the fork 110 flips from the first state to the second state under the drive of the first drive element 120, the poultry head is always supported by the hanging part 112 and limited by the wall of the hanging groove 111 under the action of gravity. In this process, the orientation of the hanging opening 113 gradually changes from horizontal to vertical. Under the action of gravity, the poultry head cannot be removed from the hanging groove 111, so that the poultry head can always be restrained by the fork 110 and be handled stably.

[0040] like Figure 1 and Figure 4As shown, the second restraint mechanism 200 includes a pressure plate 210 and a second driving element 220. The second driving element 220 is connected to the pressure plate 210 and drives the pressure plate 210 to flip, so that when the fork 110 is in the first state, the pressure plate 210 avoids the fork 110, allowing the fork 110 to flip from the first state to the second state. When the fork 110 is in the second state, it presses down on the rear side of the poultry, so that part of the poultry's head is clamped between the fork 110 and the pressure plate 210, further strengthening the restraint of the poultry and reducing the impact of poultry stress on the treatment effect.

[0041] It should be noted that in this application, "front side" and "rear side" are based on the orientation of the poultry when it is being processed, with the orientation of the poultry's head being front and the orientation of the poultry's head being rear. For example, the processing device is located in front of the hanging fork 110, and the poultry's head is hung on the hanging fork 110. The hanging fork 110 is flipped from back to front, and the part of the poultry's head is located in front of the hanging fork 110 and moves toward the processing device. After the hanging fork switches to the second state, the poultry's head is limited by the hanging fork 110 and is convenient for processing.

[0042] Furthermore, refer to Figure 1 and Figure 6 The restraint device includes a base 300. A first restraint mechanism 100 and a second restraint mechanism 200 are both mounted on the base 300. The second restraint mechanism 200 is located above the first restraint mechanism 100. When the fork 110 flips upwards, it switches from a first state to a second state. At this time, the pressure plate 210 is located above the first restraint mechanism 100, avoiding the flipping of the fork 110. After the fork 110 switches to the second state, the pressure plate 210 flips downwards and moves to the rear of the fork 110, pressing down on the bird's head to restrain it, allowing other processing devices to handle it. After the bird has been processed, the pressure plate 210 flips upwards, returns to its original position, and avoids the fork 110. The fork 110 then flips downwards, returning from the second state to the first state, allowing the bird to be hung on the fork 110 again.

[0043] In one specific embodiment, when the fork 110 is in the first state, it is perpendicular to the vertical plane; when the fork 110 is in the second state, it is parallel to the vertical plane, that is, the first direction is parallel to the horizontal plane, and the second direction is perpendicular to the horizontal plane. Thus, when the fork 110 is in the first state, the bird's head is placed horizontally into the hanging slot 111 through the hanging opening 113. When the fork 110 switches from the first state to the second state, it flips upwards under the drive of the first driving element 120. During this process, the orientation of the hanging opening 113 gradually changes from horizontal to vertical. Under the action of gravity, the bird's head is stably supported by the hanging part 112. When the fork 110 is in the first state, the pressure plate 210 is located above the fork 110 and is simultaneously in a horizontal state. After the fork 110 flips to the second state, the pressure plate 210 flips to a vertical state under the drive of the second driving element 220 and is located behind the fork 110, simultaneously pressing down on the rear of the bird.

[0044] It should be noted that the terms "horizontal" and "vertical" in this application are not limited to absolute horizontal or vertical. Considering the influence of processing, assembly and other factors, a certain degree of angular deviation is allowed.

[0045] Furthermore, this application defines the angle between the first direction and the vertical plane as greater than the angle between the second direction and the vertical plane as follows: when the fork 110 switches from the first state to the second state, it has a tendency to flip from bottom to top. That is, the top of the fork 110 in the second state is necessarily higher than the top of the fork 110 in the first state. Based on this, the angle between the first direction and the second direction in the flipping plane of the fork 110 can be less than or equal to 90°.

[0046] like Figure 1 As shown, the second restraint mechanism 200 also includes a fixed wing 230, which is installed at one end of the pressure plate 210 and can rotate with the pressure plate 210 to avoid the fork 110 when it rotates, and assist the pressure plate 210 in restraining the poultry when the fork 110 is in the second state. Specifically, the fixed wing 230 has two counter-extending wings 232, which are used to restrain the poultry's wings from the rear side of the fork 110 when the fork 110 is in the second state, reducing the poultry's wing movement margin during handling and enhancing the restraint effect.

[0047] Understandable, such as Figure 4The fixed wing 230 also includes a mounting part 231, which is connected to the pressure plate 210. Two wings 232 are respectively connected to opposite sides of the mounting part 231, and both wings 232 extend away from the mounting part 231. Along the extension direction of the wings 232, the wings 232 gradually bend towards the fork 110. When the fork 110 is in the second state, the ends of the wings 232 protrude towards the front of the fixed wing 230, thus further restricting the range of motion of the bird's wings and enhancing the restraint effect. When the fork 110 is in the second state, the fixed wing 230 flips downward with the pressure plate 210. When the pressure plate 210 covers the rear of the bird, the fixed wing 230 is located below the pressure plate 210, which can restrain the bird's wings.

[0048] The mounting part 231 is detachably connected to one end of the pressure plate 210. This detachable connection method is not limited to threaded connection, snap-fit, etc. In one embodiment, the mounting part 231 is installed on the pressure plate 210 by a threaded connection, and the threaded fastener passes through and locks the mounting part 231 and the pressure plate 210. The fixing wing 230 is hollow, and the threaded fastener can change its position in the mounting part 231, thereby adjusting the installation position of the fixing wing 230 on the pressure plate 210, so that the fixing wing 230 can be movably installed on the pressure plate 210 to match the restraint needs of poultry at different times or of different types. Furthermore, the threaded fastener can slide within the mounting part 231, enabling stepless adjustment of the position of the threaded fastener within the mounting part 231. Alternatively, the mounting part 231 and the pressure plate 210 can be connected to each other by a snap-fit. The mounting part 231 and the pressure plate 210 are respectively provided with snap-fit ​​buckles on their opposite sides. Multiple snap-fit ​​buckles can be provided on the mounting part 231 or the pressure plate 210 so that the mounting part 231 can change its mounting position on the pressure plate 210, and the fixed wing 230 can be movably mounted on the pressure plate 210.

[0049] For example, taking the mounting part 231 threadedly connected to the pressure plate 210 as an example, multiple threaded fasteners are simultaneously inserted through the mounting part 231 and the pressure plate 210, locking the mounting part 231 and the pressure plate 210 together. The multiple threaded fasteners locking the mounting part 231 and the pressure plate 210 together can strengthen the connection strength between the fixed wing 230 and the pressure plate 210, preventing the fixed wing 230 from rotating or shaking relative to the pressure plate 210.

[0050] like Figure 3 and Figure 5As shown, the hanging slot 111 has a first slot 1111 and a second slot 1112 that are interconnected. The first slot 1111 is located between the second slot 1112 and the hanging opening 113. The opening of the second slot 1112 is smaller than the opening of the first slot 1111. Along the hanging direction from the bird's head toward the hanging slot 111, the opening of the first slot 1111 first increases and then decreases, so that the first slot 1111 is thick in the middle and thin at the end. It should be noted that the hanging direction of the poultry's head toward the hanging slot 111 is the same as the arrangement direction of the hanging opening 113, the first slot 1111, and the second slot 1112. When the hanging fork 110 is in the second state, the hanging slot 111 extends through in the front-back direction so that the poultry's head can extend to the front side of the hanging fork 110, and part of the poultry is located on the rear side of the hanging fork 110, so that the poultry is hung on the hanging fork 110. The opening of the first slot 1111 and the second slot 1112 refers to the distance between two opposite slot walls of the first slot 1111 that are parallel to the horizontal plane and perpendicular to the hanging direction of the poultry's head toward the hanging slot 111 when the hanging fork 110 is in the second state, and the distance between two opposite slot walls of the second slot 1112 that are parallel to the horizontal plane and perpendicular to the hanging direction of the poultry's head toward the hanging slot 111.

[0051] When the bird's head is hung on the hanging fork 110, the bird's head is accommodated in the first groove 1111, and part of the neck is accommodated in the second groove 1112. The hanging part 112 supports the bird's neck. Since the opening of the second groove 1112 is smaller than the opening of the first groove 1111, the first groove 1111 and the second groove 1112 can respectively match the restraint requirements of the bird's head and neck, and limit the bird's head and neck.

[0052] Understandably, the opening of the hanging fork 110 at the hanging port 113 is greater than the opening of the first groove 1111, and the opening of the hanging port 113 gradually decreases in the direction of insertion of the poultry head into the hanging groove 111. The inner wall of the hanging port 113 guides the insertion of the poultry head into the hanging groove 111.

[0053] In addition, a recessed portion 114 is provided on one side of the hanging fork 110. The recessed portion 114 is located at the edge of the hanging groove 111. The surface of the recessed portion 114 is an arc surface or a curved surface. After the poultry head is hung on the hanging fork 110, the poultry head and neck come into contact with the surface of the recessed portion 114, which can reduce the discomfort caused by the pressure of the edge of the hanging fork 110 on the poultry head and reduce the stress on the poultry.

[0054] The fork 110 also has a recessed limiting groove 115. When the fork 110 is in the second state, the limiting groove 115 is located on the rear side of the fork 110 and below the hanging groove 111. The limiting groove 115 can accommodate part of the poultry's body. Under the pressing action of the pressure plate 210, the poultry can be closer to the fork 110. The pressure plate 210 and the fork 110 can stably hold the poultry and improve the restraint effect.

[0055] Furthermore, the limiting groove 115 and the recess 114 are located on opposite sides of the hanging fork 110. When the hanging fork 110 is in the second state, the recess 114 is located on the front side of the hanging fork 110, and the limiting groove 115 is located on the rear side of the hanging fork 110. Since the pressure plate 210 presses down on the rear side of the poultry, the poultry can be partially accommodated in the limiting groove 115 under the pressing action of the pressure plate 210.

[0056] The first restraining mechanism 100 includes a first connecting portion 130 and a plurality of forks 110. The first connecting portion 130 is connected to a first driving element 120. The plurality of forks 110 are arranged at intervals and installed on the first connecting portion 130. When the first driving element 120 drives the first connecting portion 130 to rotate, the plurality of forks 110 rotate synchronously with the first connecting portion 130 to simultaneously switch the states of the plurality of forks 110. In one embodiment, the first connecting portion 130 is configured as a rod-shaped member, and the plurality of forks 110 are arranged in a straight line and symmetrical with respect to the first driving element 120, so that the rotation of the forks 110 is more stable.

[0057] The second restraining mechanism 200 includes a second connecting portion 240 and a plurality of pressure plates 210. The second connecting portion 240 is connected to a second driving element 220. The plurality of pressure plates 210 are spaced apart and installed on the second connecting portion 240. When the second driving element 220 drives the second connecting portion 240 to rotate, the plurality of pressure plates 210 rotate synchronously with the second connecting portion 240. In one embodiment, the second connecting portion 240 is configured as a rod-shaped member, and the plurality of pressure plates 210 are arranged in a straight line and symmetrical with respect to the second driving element 220, so that the rotation of the pressure plates 210 is more stable.

[0058] Understandably, multiple fixed wings 230 are also provided. Each end of the pressure plate 210 is equipped with a fixed wing 230, and the number and position of the hanging forks 110 match those of the pressure plates 210. When the hanging forks 110 are in the second state, the back of the head of the bird on each hanging fork 110 is pressed down by the pressure plate 210, and the wings of the bird are restrained by the fixed wings 230, so that the bird is in a stable restrained state.

[0059] Both the first driving element 120 and the second driving element 220 can be configured as power elements capable of outputting rotational motion, such as rotary motors or electric motors. Furthermore, depending on the layout requirements of the first driving element 120 and the second driving element 220 on the base 300, the output end of the first driving element 120 can be directly connected to one end of the first connecting part 130, or the output end of the second driving element 220 can be directly connected to one end of the second connecting part 240, so that the power of the first driving element 120 and the second driving element 220 is directly transmitted to the first connecting part 130 or the second connecting part 240. Alternatively, the first driving element 120 is connected to the middle of the first connecting part 130, and the second driving element 220 is connected to the middle of the second connecting part 240. The power of the first driving element 120 or the second driving element 220 is transmitted to the first connecting part 130 or the second connecting part 240 through the transmission structure. In this way, the fork 110 is located on both sides of the first driving element 120, and the pressure plate 210 is located on both sides of the second driving element 220. The flipping synchronization of different forks 110 or different pressure plates 210 is high, and the deformation of the first connecting part 130 and the second connecting part 240 during the transmission process can be reduced.

[0060] Specifically, the transmission structure is configured as a transmission mechanism capable of switching the direction of power transmission, such as a worm gear mechanism or a bevel gear transmission mechanism. For example, taking the transmission structure connected to the second drive element 220 as an example, refer to... Figure 7 The transmission structure includes two meshing bevel gears, one of which is connected to the first drive element 120, and the other is connected to the first connecting part 130. Through the power transmission of the two bevel gears, the direction of rotation output by the first drive element 120 is switched, allowing the first drive element 120 to transmit power simultaneously in different directions through the first connecting part 130, resulting in high driving efficiency. It is understood that the transmission structure connected to the second drive element 220 can be implemented using a similar structure.

[0061] like Figure 8 As shown, the base 300 includes a base 310, a first movable part 320, and a second movable part 330. Both the first movable part 320 and the second movable part 330 are movably connected to the base 310. The base 310 supports and fixes the first movable part 320 and the second movable part 330. The first restraining mechanism 100 is installed on the first movable part 320, and the second restraining mechanism 200 is installed on the second movable part 330. By changing the installation position of the first movable part 320 and the second movable part 330 on the base 310, the relative position of the first restraining mechanism 100 and the second restraining mechanism 200 can be adjusted, so that the first restraining mechanism 100 and the second restraining mechanism 200 can cooperate with each other to restrain poultry of different types and at different times.

[0062] Specifically, taking the first moving part 320 as an example, the first moving part 320 is mounted on the rear side of the base 310, and the first driving element 120 is mounted on the front side of the base 310. The first moving part 320 is mounted to the base 310 by a threaded connection. One of the first moving part 320 and the base 310 is provided with a slotted hole, and the other is provided with a mounting hole. Threaded fasteners pass through the slotted hole and the mounting hole, locking the first moving part 320 to the base 310, thus fixing the first moving part 320 to the base 310. In addition, the slotted hole extends in multiple directions simultaneously, allowing the first moving part 320 to be adjusted in different directions on the base 310; for example, the slotted hole extends in two mutually perpendicular directions within the plane of the base 310.

[0063] The movable connection between the first moving part 320, the second moving part 330, and the base 310 can also be achieved by providing a moving module on the base 310. Taking the first moving part 320 as an example, the moving module is installed on the base 310, and both the first moving part 320 and the first driving element 120 are connected to the moving module. The moving module is used to drive the first moving part 320 and the first driving element 120 to move in at least one direction, so as to change the position of the first moving part 320 and the base 310.

[0064] like Figure 6 As shown, this utility model also provides a poultry processing device, including the aforementioned restraint device and a beak trimming device 400. The beak trimming device 400 is used to trim the beak of poultry. When the fork 110 is in the second state, the beak trimming device 400 is located in front of the fork 110, and the pressure plate 210 is located behind the fork 110. The pressure plate 210 presses down on the rear of the poultry, causing the poultry to extend towards the front of the fork 110 and into the beak trimming device 400 for beak trimming. Under the limiting and pressing action of the first restraint mechanism 100 and the second restraint mechanism 200, the poultry is kept in a stable restraint state, which facilitates the beak trimming by the beak trimming device 400 and improves the beak trimming accuracy.

[0065] In addition, the poultry processing equipment also includes an injection device 500, which is used to inject poultry when the fork 110 is in the second state to achieve viral and disease immunization. At least part of the injection device 500 is connected to the pressure plate 210 and rotates synchronously with the pressure plate 210. Thus, when the pressure plate 210 rotates to press the rear of the poultry, the injection device 500 moves into position simultaneously, allowing for further injection of the poultry without the need for repeated repositioning of the injection device 500, which helps to improve the processing efficiency of poultry.

[0066] It should be noted that poultry processing equipment may also include other processing devices, such as insemination devices.
