Abstract

This invention discloses a post-slaughter testing device for pigs, relating to the field of testing and sampling technology. To address efficiency issues, the device specifically includes a top plate. A limiting frame is bolted to the bottom of the top plate. The limiting frame contains a driving mechanism, and its inner wall is movably connected to multiple sets of hook mechanisms driven by the driving mechanism to suspend the pigs. A fixing frame is bolted to the bottom outer wall of the top plate. This fixing frame is connected to a sampling mechanism via a synchronization mechanism. The fixing frame cooperates with the hook mechanisms. This invention, by setting up the hook mechanism and using a synchronization mechanism to intermittently "transmit" the sampling mechanism and the hook mechanism, ensures that when the hook mechanism suspends the pig and moves to the sampling mechanism, the hook mechanism drives the sampling mechanism to move synchronously. This eliminates the need for stopping the transport and waiting, as well as the need to stop the pig's movement, thus shortening the ineffective time and greatly improving efficiency.

Description

Technical Field

[0001] This invention relates to the field of detection and sampling technology, and in particular to a detection device for pigs after slaughter. Background Technology

[0002] After slaughter, pigs are transported by hoisting. During this process, samples of the pork are taken and then tested to ensure the quality of the pork.

[0003] A search revealed a Chinese patent publication number CN 119023314 B, which discloses a real-time detection device for pork storage and transportation. The device includes components such as an adsorption element, a cutting element, and a suspended conveying device. It uses an adsorption element located on one side of the suspended conveying device to adsorb pork, then uses the cutting element to cut the pork, and finally places the cut sample into a storage box for subsequent pork testing.

[0004] The aforementioned patent has the following shortcomings: the positions of the adsorption and cutting components relative to the suspension conveying device are fixed, which means that the suspension conveying device needs to be stopped during sampling. However, since the pork is transported in a suspended manner, the pork will swing back and forth when the conveying stops. Positioning adsorption and cutting can only be performed after the swing stops, which wastes the time waiting for the pork to stop swinging and results in low sampling efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a post-slaughter testing device for pigs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A post-slaughter testing device for pigs includes a top plate. A limit frame is fixed to the bottom of the top plate by bolts. A drive mechanism is provided inside the limit frame, and multiple sets of hook mechanisms for suspending pigs are movably connected to the inner wall of the limit frame and driven by the drive mechanism. A fixing frame is fixed to the bottom outer wall of the top plate by bolts. The fixing frame is connected to a sampling mechanism for sampling through a synchronous mechanism. The fixing frame cooperates with the hook mechanisms.

[0008] The hook mechanism includes a movable frame and a hook. The hook is slidably connected to one side of the movable frame, and a sealing plate is fixed to the top outer wall of the hook by bolts. The bottom of the sealing plate is fastened to the movable frame by a spring, and a limit post is fixed to the bottom outer wall of the sealing plate.

[0009] The synchronization mechanism includes a sliding plate and a limiting plate. The sliding plate is horizontally slidably connected to the inner side of the fixed frame through a guide rod, and the limiting plate is longitudinally slidably connected to the inner side of the sliding plate. A second spring is sleeved on the outer wall of the guide rod. An inclined sliding groove is formed on the back of the fixed frame, and the rear side of the limiting plate is in rolling limit fit with the inner wall of the inclined sliding groove through a first roller.

[0010] Preferably: A collision sensor is fixed to the outer wall of one side of the limiting plate through a bolt. The collision sensor is communicatively connected to a control cabinet, and the control cabinet is controllably connected to the sampling mechanism.

[0011] Furthermore: The sampling mechanism includes a support frame, a displacement driving component, and a sampling component. The support frame is fixed to the outer wall of the bottom of the sliding plate through a bolt. Two symmetric support plates are fixed to the side wall of the support frame through bolts. The sampling component is arranged inside the support plates, and the displacement driving component is fixed to the support frame and is used to drive the sampling component to move linearly and rotate.

[0012] Based on the foregoing solution: The sampling component includes a housing, a negative pressure suction head, and a double-edged blade. The negative pressure suction head is fixed to the front side of the housing. The double-edged blade is rotatably connected to the outer wall of the housing through a rotating arm. A first motor and an air pump are arranged inside the housing. The output shaft of the first motor is fixed to the side wall of the rotating arm, and the air pump is connected to the negative pressure suction head through a pipeline.

[0013] In a better solution of the foregoing solution: Two horizontally arranged and parallel straight grooves are formed on the inner wall of the support plate. An arc groove is connected to the end of the straight groove at the bottom, and the center position of the arc groove coincides with the end of the straight groove at the top. The side wall of the housing is in movable limit fit with the straight groove and the arc groove through a "soil"-shaped rod.

[0014] As a further solution of the present invention: The displacement driving component includes a connecting rod and a telescopic rod. The telescopic rod is fixed to the rear side wall of the support frame through a bolt. The telescopic end of the telescopic rod penetrates through the support frame and then is rotatably connected to one end of the connecting rod. The other end of the connecting rod is rotatably connected to the side wall of the housing, and the hinge point of the housing and the connecting rod is lower than the height of the "soil"-shaped rod at the top. At the same time, the height of the telescopic rod is greater than the height of the housing.

[0015] Meanwhile, a slide rail is fixed to the bottom side wall of the support frame through a bolt. An electric slider is slidably fitted on the outer wall of the slide rail. A plurality of sample boxes for accommodating samples are arranged on the top outer wall of the electric slider.

[0016] As a preferred solution of the present invention: The driving mechanism includes multiple rows of chains, a second motor, and a sprocket. A limiting groove is formed on the inner wall of the limiting frame. The multiple rows of chains are in movable limit fit inside the limiting groove, and the multiple rows of chains are traction-connected to the side wall of the moving frame through a traction rope.

[0017] Meanwhile, an "L"-shaped frame is fixed to the inner side of the limiting frame by bolts, and the movable frame is limited and matched to the inner wall of the "L"-shaped frame by two rollers.

[0018] As a preferred embodiment of the present invention: the second motor is fixed to the side wall of the limiting frame by bolts, the sprocket is fixed to the outer wall of the output shaft of the second motor, and the sprocket meshes with the side wall of the multi-row chain.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention, by setting up a hook mechanism and a synchronization mechanism to intermittently "transmit" the sampling mechanism and the hook mechanism, achieves the following: Firstly, when the hook mechanism suspends a live pig and moves to the sampling mechanism, it can drive the sampling mechanism to move synchronously, thus eliminating the need for stopping the transport or waiting due to the swaying of the pork, shortening the ineffective time and greatly improving efficiency. Secondly, by cleverly utilizing the height difference, when the hook mechanism is not suspending pork, even if it moves to the sampling mechanism, it will not trigger synchronous movement, further improving efficiency. Thirdly, the entire process is fully automatically identified and carried out, increasing the degree of automation.

[0021] 2. In this invention, by setting up multiple sets of hook mechanisms, multiple hook mechanisms naturally form multiple workstations, thereby enabling other processing operations for pigs to be performed at other workstations besides the detection workstation, increasing the integration and compactness of the entire pig processing process.

[0022] 3. This invention, by setting up components such as a negative pressure suction head and a double-edged blade, uses adsorption to fix pork, and then uses the double-edged blade to cut it, thereby ensuring the reliability of sampling.

[0023] 4. In this invention, by setting the shell to be rotatable, it can rotate downwards before placing the sample, thereby ensuring the reliability of sample collection. In addition, the shell is connected to the support plate by using arc grooves, "E"-shaped rods and straight grooves, and the shell is driven by connecting rods and telescopic rods. Thus, through simple limiting and path guidance, the rotation and translation of the shell can be realized sequentially by using a single telescopic rod as the drive, simplifying the power layout and control logic.

[0024] 5. This invention, by setting up multiple sample boxes and coordinating with electric sliders and slide rails, enables the physical separation of different sample boxes by sliding the slide rails to switch their positions after a single sampling, facilitating identification and subsequent detection.

[0037] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0038] Embodiments of the present invention 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 the present invention, and should not be construed as limiting the present invention.

[0039] Example 1: A post-slaughter detection device for pigs, such as... Figure 1-11 As shown, the device includes a top plate 1. A limit frame 2 is fixed to the bottom of the top plate 1 by bolts. A drive mechanism 7 is provided inside the limit frame 2. The inner wall of the limit frame 2 is movably connected to multiple sets of hook mechanisms 6 that are driven by the drive mechanism 7 and used to suspend pigs. A fixing frame 3 is fixed to the bottom outer wall of the top plate 1 by bolts. The fixing frame 3 is connected to a sampling mechanism 5 for sampling through a synchronization mechanism 4. The fixing frame 3 cooperates with the hook mechanisms 6.

[0040] The hook mechanism 6 includes a movable frame 8 and a hook 11. The hook 11 is slidably connected to one side of the movable frame 8, and a sealing plate 9 is fixed to the top outer wall of the hook 11 by bolts. The bottom of the sealing plate 9 is fastened to the movable frame 8 by a spring 10, and a limit post 12 is fixed to the bottom outer wall of the sealing plate 9.

[0041] The synchronization mechanism 4 includes a slide plate 24 and a limiting plate 15. The slide plate 24 is laterally slidably connected to the inner side of the fixed frame 3 via a guide rod 14. The limiting plate 15 is longitudinally slidably connected to the inner side of the slide plate 24. A second spring 13 is sleeved on the outer wall of the guide rod 14. An inclined slide groove 25 is opened on the back of the fixed frame 3. The rear side of the limiting plate 15 is rolled and limited to the inner wall of the inclined slide groove 25 via a first roller 26.

[0042] In use, the slaughtered pig can be suspended using the hook 11. During suspension, the hook 11 descends under gravity, causing the sealing plate 9 to descend until the limiting post 12 contacts the bottom upper surface of the moving frame 8. Then, the drive mechanism 7 drives the moving frame 8 to move. When the moving frame 8 reaches the sampling mechanism 5, the edge of the limiting plate 15 contacts the edge of the sealing plate 9, limiting each other. This limiting action causes the limiting plate 15 to move synchronously, which in turn drives the entire sampling mechanism 5 to move synchronously via the sliding plate 24. During this movement, the sampling mechanism 5 performs sampling, while the sliding plate 24 slides laterally under the influence of the sealing plate 9. During the process, due to the cooperation between the inclined slide 25 and the roller 26, the height of the slide plate 24 will gradually increase until the sampling mechanism 5 completes the sampling. At this time, the slide plate 24 reaches the highest position. At this time, the limiting plate 15 and the sealing plate 9 no longer overlap in height. The limiting effect of the sealing plate 9 on the limiting plate 15 disappears. The slide plate 24 rebounds under the elastic force of the spring 13. At the same time, when the hook 11 moves to the sampling mechanism 5 and does not hang the pig, the sealing plate 9 is in the upper position under the elastic force of the spring 10. At this time, even if the sealing plate 9 moves to the limiting plate 15, it will not limit each other due to the height difference, and the sampling mechanism 5 will not take a sample.

[0043] This device, by setting up a hook mechanism 6 and a synchronization mechanism 4 to intermittently "transmit" the sampling mechanism 5 and the hook mechanism 6, allows the hook mechanism 6 to drive the sampling mechanism 5 to move synchronously when it suspends a live pig and moves to the sampling mechanism 5. This eliminates the need for stopping the transport or waiting due to the pork swinging, reducing ineffective time and greatly improving efficiency. Furthermore, by cleverly utilizing the height difference, the hook mechanism 6 will not trigger synchronous movement even when it moves to the sampling mechanism 5 when it is not suspending pork, further improving efficiency. In addition, the entire process is fully automatically identified and carried out, increasing the degree of automation.

[0044] In addition, by setting up multiple sets of hook mechanisms 6, the multiple hook mechanisms 6 naturally form multiple workstations, thereby enabling other processing operations for pigs to be performed at other workstations besides the inspection workstation, increasing the integration and compactness of the entire pig processing process.

[0045] To solve the problem of opening and closing sampling mechanism 5; such as Figure 3As shown, a collision sensor 23 is fixed to the outer wall of one side of the limit plate 15 by bolts. The collision sensor 23 is communicatively connected to a control cabinet, and the control cabinet is controllably connected to the sampling mechanism 5. In this embodiment, only the entire control process needs to be implemented, so the installation position and type of the control cabinet are not limited. It only needs to have functions such as signal reception, signal processing, and electronic component control. When the sealing plate 9 contacts the side of the limit plate 15, a collision vibration will occur. Taking the collision vibration as a signal, the control cabinet controls the sampling mechanism 5 to perform sampling.

[0046] To solve the sampling problem; as Figure 3 , 7 As shown in FIGS. 7 and 8, the sampling mechanism 5 includes a support frame 22, a displacement driving component 16, and a sampling component 17. The support frame 22 is fixed to the bottom outer wall of the slide plate 24 by bolts. Two symmetric support plates 21 are fixed to the side wall of the support frame 22 by bolts. The sampling component 17 is arranged inside the support plates 21. The displacement driving component 16 is fixed to the support frame 22 and the displacement driving component 16 is used to drive the sampling component 17 to perform linear movement and rotational movement.

[0047] The sampling component 17 includes a housing 27, a negative pressure suction head 28, and a double-edged blade 32. The negative pressure suction head 28 is fixed to the front side of the housing 27. The double-edged blade 32 is rotatably connected to the outer wall of the housing 27 through a rotating arm 31. A motor 29 and an air pump 30 are arranged inside the housing 27. The output shaft of the motor 29 is fixed to the side wall of the rotating arm 31. The air pump 30 is connected to the negative pressure suction head 28 through a pipeline.

[0048] Two horizontally arranged and parallel straight grooves 37 are formed in the inner wall of the support plate 21. An arc groove 35 is communicated with the end of the straight groove 37 at the bottom. The center position of the arc groove 35 coincides with the end of the straight groove 37 at the top. The side wall of the housing 27 is movably and limitedly fitted to the straight grooves 37 and the arc groove 35 through a "soil"-shaped rod 36.

[0049] The displacement driving component 16 includes a connecting rod 33 and a telescopic rod 34. The telescopic rod 34 is fixed to the rear side wall of the support frame 22 by bolts. The telescopic end of the telescopic rod 34 penetrates through the support frame 22 and is rotatably connected to one end of the connecting rod 33. The other end of the connecting rod 33 is rotatably connected to the side wall of the housing 27. The hinge point between the housing 27 and the connecting rod 33 is lower than the height of the "soil"-shaped rod 36 at the top. At the same time, the height of the telescopic rod 34 is greater than the height of the housing 27.

[0050] When the control cabinet sends a control signal, the telescopic rod 34 first extends upon receiving the signal. At this time, both "E"-shaped rods 36 are engaged in the two straight grooves 37. Through the limiting of the straight grooves 37 and the "E"-shaped rods 36, the housing 27 moves laterally until the negative pressure suction head 28 contacts the sampling point of the pork. Then, the air pump 30 extracts the air from the negative pressure suction head 28, using the negative pressure inside the negative pressure suction head 28 to adsorb and fix the pork. Subsequently, the motor 29 starts and drives the rotating arm 31 to rotate, using the double-edged blade 32 to cut and separate the adsorbed pork. After separation, the telescopic rod 27 extends the telescopic rod 34 to the sampling point of the pork. When the retracting rod 34 retracts, in the initial stage of retraction, the two "earth"-shaped rods 36 are still engaged inside the two straight grooves 37, moving backward in a straight line until the two "earth"-shaped rods 36 reach the end of the straight grooves 37. Since the bottom straight groove 37 is connected to the arc groove 35, the bottom "earth"-shaped rod 36 will continue to move along the arc groove 35, while the top "earth"-shaped rod 36 stops. At this time, the housing 27 will rotate downward until it reaches the sampling angle. Then, the air pump 30 blows air onto the negative pressure suction head 28 to discharge the sample, completing one sampling operation.

[0051] This device, by setting up components such as a negative pressure suction head 28 and a double-edged blade 32, uses suction to fix pork, and then uses the double-edged blade 32 to cut it, thereby ensuring the reliability of sampling.

[0052] In addition, by making the housing 27 rotatable, it can rotate downwards before placing the sample, thus ensuring the reliability of sample collection. Furthermore, the housing 27 is connected to the support plate 21 by the arc groove 35, the "earth" shaped rod 36, and the straight groove 37. At the same time, the housing 27 is driven by the connecting rod 33 and the telescopic rod 34. Thus, through simple limiting and path guidance, the rotation and translation of the housing 27 can be realized sequentially by using a single telescopic rod 34 as the drive, simplifying the power layout and control logic.

[0053] This was originally intended to solve the collection problem, such as Figure 3 As shown, the bottom sidewall of the support frame 22 is fixed with a slide rail 20 by bolts, and an electric slider 19 is slidably fitted on the outer wall of the slide rail 20. The top outer wall of the electric slider 19 is provided with a plurality of sample boxes 18 for holding samples.

[0054] When the housing 27 rotates and the sample is discharged using the negative pressure suction head 28, the sample box 18 can be stored.

[0055] This device, by setting up multiple sample boxes 18 and cooperating with electric sliders 19 and slide rails 20, can switch the position of sample boxes 18 by sliding the slide rails 20 after a single sampling, thereby achieving physical separation of different samples, which is convenient for identification and subsequent detection.

[0056] In this embodiment, after slaughtering, the pig can be suspended using the hook 11. During suspension, the hook 11 descends under gravity, causing the sealing plate 9 to descend until the limiting post 12 contacts the bottom upper surface of the moving frame 8. Subsequently, the drive mechanism 7 drives the moving frame 8 to move. When the moving frame 8 moves to the sampling mechanism 5, the edge of the limiting plate 15 contacts the edge of the sealing plate 9 and mutually limits each other. This limiter drives the limiting plate 15 to move synchronously, thereby driving the entire sampling mechanism 5 to move synchronously through the sliding plate 24. At the same time, when the sealing plate 9 contacts the side of the limiting plate 15, a collision vibration will occur, thereby causing the sampling mechanism 5 to move synchronously. The impact vibration serves as a signal, prompting the control cabinet to issue a control signal. First, the telescopic rod 34 receives the signal and extends. At this time, both "earth"-shaped rods 36 engage with the two straight grooves 37. Through the limiting action of the straight grooves 37 and the "earth"-shaped rods 36, the housing 27 moves laterally until the negative pressure suction head 28 contacts the sampling point of the pork. Then, the air pump 30 extracts the air from the negative pressure suction head 28, using the negative pressure within the suction head 28 to adsorb and fix the pork. Subsequently, the motor 29 starts, driving the rotating arm 31 to rotate, using the double-edged blade 32 to cut and separate the adsorbed pork. After separation, the telescopic rod 34 retracts. In the initial stage of retraction, the two "earth"-shaped rods 36 engage with the two straight grooves 37. The "soil"-shaped rod 36 remains fitted inside the two straight grooves 37, moving backward in a straight line until the two "soil"-shaped rods 36 reach the ends of the straight grooves 37. Since the bottom straight groove 37 connects to the arc groove 35, the bottom "soil"-shaped rod 36 continues to move along the arc groove 35, while the top "soil"-shaped rod 36 stops. At this point, the housing 27 rotates downward until it reaches the sampling angle. Then, the air pump 30 blows air onto the negative pressure suction head 28, expelling the sample and storing it in the sample box 18, completing one sampling operation. Simultaneously, the sliding plate 24 slides laterally as it is driven by the sealing plate 9. With the cooperation of the inclined slide 25 and the roller 26, the height of the slide plate 24 will gradually increase until the sampling mechanism 5 completes the sampling. At this time, the slide plate 24 reaches the highest position. At this time, the limiting plate 15 and the sealing plate 9 no longer overlap in height. The limiting effect of the sealing plate 9 on the limiting plate 15 disappears. The slide plate 24 rebounds under the elastic force of the spring 13. At the same time, when the hook 11 moves to the sampling mechanism 5 and does not hang the pig, the sealing plate 9 is in the upper position under the elastic force of the spring 10. At this time, even if the sealing plate 9 moves to the limiting plate 15, it will not limit each other due to the height difference, and the sampling mechanism 5 will not take a sample.

[0057] Example 2: A post-slaughter detection device for pigs, such as... Figure 9 , 10As shown in Figure 11, in order to solve the driving problem, this embodiment makes the following improvements based on embodiment 1: The driving mechanism 7 includes a multi-row chain 39, a motor 43 and a sprocket 44. The inner wall of the limiting frame 2 is provided with a limiting groove 38. The multi-row chain 39 is movably limited and fitted inside the limiting groove 38, and the multi-row chain 39 is connected to the side wall of the movable frame 8 by a traction rope 40.

[0058] For details, please refer to Figure 10 The synchronization mechanism 4 adopts a four-row arrangement. One chain at the top and one chain at the bottom are limited by the limiting groove 38 of the limiting frame 2, while the two chains in the middle are relatively exposed. Therefore, the middle chain is used to connect the moving frame 8 and the sprocket 44.

[0059] The inner side of the limiting frame 2 is fixed with an "L"-shaped frame 42 by bolts, and the movable frame 8 is rolled and limited by rollers 41 to fit the inner wall of the "L"-shaped frame 42.

[0060] The second motor 43 is fixed to the side wall of the limiting frame 2 by bolts, and the sprocket 44 is fixed to the outer wall of the output shaft of the second motor 43, and the sprocket 44 is engaged with the side wall of the multi-row chain 39.

[0061] In this embodiment, when the second motor 43 is started, it can drive the sprocket 44 to rotate, thereby driving the multi-row chain 39 to move in the limiting groove 38 through meshing, and thus driving the moving frame 8 to move through the traction rope 40.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
